However, according to 阅读 1.according to按照;根据 (1)According to experts, Jupiter, which orbits the Sun like the Earth, is the largest planet in the solar system. ① a widely accepted theory②, the universe began with a “Big Bang” that threw matter in all directions. After that, atoms began to form and combine to create stars and other bodies. 没有人确切知道地球是怎样开始形成的,因为在很早很早以前它就形成了。然而,一种普遍为人们所接受的理论是:宇宙起源于一次大爆炸,这次大爆炸将物质投射到四面八方。然后,原子开始形成并结合 成恒星和其他天体。 For several billion years after the “Big Bang”, the earth was still just a cloud of dust. What it was to become was uncertain until between 4.5 and 3.8 billion years ago when the dust settled into a solid globe. The earth became so violent③ that it was not clear whether the shape would last or not. It exploded loudly with fire and rock. They were in time④ to produce carbon, nitrogen, water vapour and other gases, which were to make the earth’s atmosphere⑤. What is even more important is that as the 据专家介绍,木星是太阳系中最大的一颗行星,与地球一样环绕太阳运转。 (2)The Olympic Flame is lit by the High Priestess according to an ancient method, using the sun and a parabolic mirror.按照古代的方法,女祭司利用太阳和抛面镜来点燃奥运圣火。 2.theory n. 学说;理论 (1)American astronomer and mathematician who investigated double stars and developed the wave theory of gravitation.西易,托马斯 杰斐逊 杰克逊1866-1962美国天文学家和数学家,他观测了双星座并发展了万有引力波理论。 (2)Copernicus’ theory of the solar system were once dismissed as erroneous and had to win out over bitter opposition. 哥白尼关于太阳系的学说曾经被看作是错误的东西,曾经经历艰苦的斗争。 (3)Darwin spent more than twenty years working on his theory of evolution.达尔文花了二十余年时间研究他的进化论。 3.violent adj. 猛烈地;激烈的;强暴的 (1)Tornadoes are violent whirlwinds which vary in their width from a few yards to 1300 feet. 龙卷风是一种猛烈的旋风,其直径从几码到1300 英尺。 (2)Violent crime is only one of the maladies afflicting earth cooled down, water began to appear on its surface. 大爆炸后好几十亿年过去了,但地球还只是一团尘埃。随后它会变成什么没人能知道,直到38—45亿年前,这团尘埃才慢慢地形成一个固体的球状物。地球(开始)变得激烈动荡,不知道这个固体形状是否会继续存在下去。它(地球)猛烈的爆炸喷出了烈火与岩石,最终产生了碳、氮气、水蒸气和其他多种气体,从而形成了地球的大气层。更为重要的是,地球冷却了下来,地球的表面就开始出现了水。 Water had also appeared on other planets like Mars but unlike⑥ the earth, it had disappeared later. It was not immediately obvious that water was to be fundamental to the development of life. What many scientists believe is that the continued presence of water allowed the earth to dissolve harmful⑦ gases and acids into the oceans and modern society. 暴力犯罪仅仅是危害社会的弊病之一 [拓展] violence n. 暴力 violently adv. 暴力地;激烈地 (3)The violence and bad language in the program shocked many of the viewers. 节目中的暴力场面和难听的粗话使许多观众感到震惊。 (4)They have come into conflict, sometimes violently. 他们产生了矛盾,有时矛盾还非常激烈。 [典型例题] Hearing what I said, she became angry, went into her room and shut the door _____(violent). 【点拨】violently 所填的词修饰动词,所以用副词形式。violently猛烈地。 4.in time 迟早;早晚,相当于sooner or later; 及时;不迟 (1)If you work hard, you will succeed in time. 如果你努力工作,你最终会成功的。 (2)I intended to catch the early train, but I didn’t get up in time. 我本来打算赶早班的火车,但是我起晚了。 (3)Firemen reached the house on fire in time. 消防队员及时赶到那幢失火的房子。 seas. This produced a chain reaction, which made it possible for life to develop. 在火星这些其他行星上都出现了水,但和地球不同的是,这些水后来都消失了。水会对生命的发展起 关键作用,这一点在当时并不明显。很多科学家相信,由于地球上长期有水存在,它使得地球得以把有害气体和酸性物质溶解在海洋里。这就产生了一系列的反应,使得生命就有可能开始发展了。 Many millions of years later, the first extremely small plants began to appear on the surface of the water. They multiplied and filled the oceans and seas with oxygen, which encouraged the later development of early shellfish and all sorts of fish. Next, green plants began to grow on land. They were followed in time by land animals. Some were insects. Others, called amphibians, [拓展] in time for…后接名词 in time to do (4)I saved my bacon by arriving just in time for the meeting. 我刚好及时到会,才算没受责备。 (5)The car came to a halt just in time to prevent an accident. 汽车及时停下,避免了一场车祸。 5.atmosphere n. 大气层;气氛 (1)From these observations we conclude that the moon has little or no atmosphere. 由这些观察,我们确信月球很少或根本没有大气层。 (2)Spacecraft re-entering the earth’s atmosphere are affected by gravity forces. 航天器重返大气层是由於重力的作用。 6.unlike prep. 不同;不像 (1)In addition, observations of space around our Sun have revealed that unlike the rest of the galaxy, space near us has little interstellar gas in it. 此外,对太阳周围太空的观察还显示,与银河系的其他部分不同,我们周围的太空中星际气体很少。 (2)Jupiter is unlike the Earth in almost every way. 木星与地球几乎完全不同。 were able to live on land as well as in the water. Later when the plants grew into forests, reptiles appeared for the first time. They produced young generally by laying eggs⑧. After that, some huge animals, called dinosaurs, developed. They laid eggs too and existed⑨ on the earth for more than 140 million years. However, 65million years ago the age of the dinosaurs ended. Why they suddenly disappeared still remains a mystery. This disappearance made possible the rise of mammals on the earth. These animals were different from all life forms in the past, because they gave birth to(10) young baby animals and produced milk to feed them. [用法拓展] alike adj. 相似的;同样的; adv. 一样;以同样的方式 likely adj. 可能的; (3)These kittens look exactly alike how can you tell which is which? 这些小猫看上去一模一样--你怎么能分出哪个是哪个? (4)The boss treats everyone alike. 老板对大家一视同仁。 (5)John is likely to be in London this autumn. 今年秋天约翰可能在伦敦。 7.harmful adj.有害的 (1)Harmful radiations do not reach the earth because the atmosphere screens them out. 有害的辐射由于得到大气屏蔽无法到达地球。 (2)The Earth is a spacecraft too, our atmosphere acting as a shield against harmful radiation and space debris.地球跟宇宙飞船完全一样,其周围的大气对有害的辐射和宇宙碎片起到防护作用。 [用法拓展] harm n. 伤害;损害,常构成do harm to…或do sb. harm结构。 vt. 伤害;损害 (3)Strong sunlight can harm your eyes. 好几百万年以后,水的表面开始出现了极小的植物。它们繁殖起来就使得海洋充满了氧气,这为早期的贝类及其他各种鱼类后来的进化创造了条件。接着,绿色植物开始出现在陆地上。随后,陆地上出现了动物,其中有一些是昆虫,另外一些叫两栖动物,它们既能在陆上生活,也能在水里生存。后来,当植物长大成了森林的时候,爬行动物出现了。它们一般是通过孵蛋而繁衍后代的。再后来一些叫做恐龙的巨型动物出现了。它们也生蛋,在地球上生存了一亿四千多万年。然而,六千五百万年前,恐龙时代结束了。 Finally about 2.6 million years ago some small clever animals, now with hands and feet, appeared and spread all over the earth. Thus they have, in their turn(11), become the most important animals on the planet. But they are not looking after the earth very well. They are putting too much carbon dioxide into the atmosphere, which prevents(12) heat from escaping from the earth into space. As a result of this, many scientists believe the earth may become too hot to live on. So whether life will continue on the 强光对你的眼睛有害。 (4)The polluted air given off by cars will do great harm to our health.汽车排出的废气对人体有很大的伤害。 8. lay eggs 产卵;下蛋 (1)The old woman reckoned the number of eggs laid by the hens during the month. 老太太数了一下这个月里母鸡下了多少蛋。 (2)Do you know when animals which lay eggs appeared on earth? 你知道产卵的动物适合是在地球上出现的吗?

Don’t keep him waiting.我们快一点,不要让他等着。 [典型例题] Many fast-growing countries are less concerned with protecting ______(them) against climate change. 【点拨】themselves 句子的主语和所填的词指的是同一事物,所以用反身代词。protect oneself against/from保护自己免受……的侵害。 Reading中长难句 What it was to become was uncertain until between 4.5 and 3.8 billion years ago when the dust settled into a solid globe. a)本句的句式比较复杂,从句子的总体以结构看,这是一个含有时间状语从句的复合句。主句中有一个what引导的主语从句,what在从句中作become的表语,在时间状语从句中含有一个when引导的定语从句。 b) until是非常重要的连接词,其主要用法如下: ①用于否定句, 修饰非延续性动词, 表示该动作的开始时间。“not...until...”一般译为“直到……才……”。 Life didn’t appear until the earth was formed. 直到地球形成生命才出现。 ②用于肯定句, 修饰延续性动词,表示该动作或状态的终止时间。until有“直到”之意。 More and more water increased over the earth until they covered all the high mountains. 地面上的水越来越多,直到淹没了所有的高山。 ③强调肯定句中的until时间状语(从句), 一般套用“It is / was until... that...”句型;强调否定句中的until时间状语(从句), 可套用“It is/ was not until... that...”句型。 It was not until the sun set down that they got to the place. 直到太阳下山了他们才到达那个地方。 ④not until位于句首时,句子要用倒装语序。 Not until he read the book did he know something about astronomy. 直到他读了那本书,他才对天文学有所了解。 2. The earth became so violent that it was not clear whether the shape would last or not. a)该句是一个含有结果状语从句的复合句,在从句中含有一个主语从句,其中it是形式主语,whether引导的句子是真正的主语。 b)so…that…如此……以至于…… The light of the sun is so strong that we can’t look at it directly. 太阳的光太强了,我们不能直接观看。 3. What is even more important is that as the earth cooled down, water began to appear on its surface. a) 该句是一个含有表语从句的复合句,what引导的句子作主语,在that引导的表语从句中含有一个as引导的时间状语从句。 b) cool down冷却;平静 It took Charles a long time to cool down after the argument about the solar system. 有关太阳系的争论过后好久,查尔斯才得以平静下来。 He is too excited; we must do something to make him cool down. 他太激动了;我们得没法使他冷静下来。 4. This produced a chain reaction, which made it possible for life to develop. 句中的it是形式宾语,真正的宾语式不定是短语to begin to…。it作形式宾语时常用在find/make/think/consider+it+adj./n.+ to do结构中。 We find it impossible to climb to the top of the hill in such bad weather. 这么坏的天气,我们发现爬到山顶是不可能的。 He made it a rule to observe stars every evening. 他每天晚上观测星星已成了习惯。 We think it our duty to help you out of trouble. 我们认为帮助你摆脱困境是我们的责任。 [典型例题] Do you think ____ difficult to guess the meaning of the word without referring to the dictionary? 【点拨】it 在这里it是形式宾语,代替后面的不定式短语。 Comprehending理 解 1 Read the passage carefully and analyse its structure.

We visited the moon in our spaceship①! 1.spaceship n. 宇宙飞船 (1)The spaceship will soon be launched, and the people at control have already begun to count down. 宇宙飞船很快就要发射了,控制室的人已经开始在倒数了。 (2)The scientists are able to calculate accurately when the spaceship will reach the moon. 我的朋友李彦平是一位天文学家,上个月我有幸得到一个机会同他一起去太空旅行。我们乘宇宙飞船参观了月球。 Before we left, Li Yanping explained to me that the force of gravity would change three times on our journey and that the first change would be the most powerful. Then we were off. As the rocket rose into the air, we were pushed back into our seats because we were trying to escape the pull② of the earth’s gravity.(1) It was so hard that we could not say anything to each other. Gradually the weight lessened and I was able to talk to him. “Why is the spaceship not falling back to the earth? On the earth if I fall from a tree I will fall to the ground.” I asked. “We are too far from the earth now to feel its pull,” he explained, “so we feel as if there is no gravity at all. (2)When we get closer to the moon, we shall feel its gravity pulling us, but it will not be as strong a pull as the earth’s”. I cheered up③ immediately and floated weightlessly around in our spaceship cabin watching the earth become smaller and the moon larger(3). 科学家能准确地计算出太空船什么时候抵达月球。 2.pull n.拉力 vt. 拖;拉 (1)The moon’s pull affects the tides on earth. 月亮的引力影响地球上的潮汐。 (2)The lecture on solar pulled a great crowd. 有关太阳系的讲演吸引了一大群人。 (3)As an object gets away from the earth, the strength of the pull weakens. 当一个物体离开地球时,地球引力的强度就减弱。 [拓展] pull up (使)停下来;向上拉 pull down拆毁 pull over把……开到路边 (4)The driving instructor told me to pull up at the post office. 驾驶教练让我在邮局停车。 (5)Plans have been put forward to pull down and rebuild the area. 已提出计划,要把这个地区的房屋推掉重建。 (6)I shouted to the driver of the tractor to pull over and let me through. 我向拖拉机手喊,要他把拖拉机开到路边让我过去。 3.cheer up高兴起来;感到振奋 在启程以前,李彦平向我解释说,在我们的航行中会有三次引力的改变,而第一次的改变将是最强的。随后我们就启航了。随着火箭的升空,由于我们在努力挣脱地球的引力,我们被向后推在座位上。这种引力太强了,以至于我们彼此间都不能说话了。随后,这个力量慢慢减小,我才能够同他讲话。我问道:“为什么太空船不会向后朝地球的方向落下去呢?在地球上的时候,如果我从树上掉下来,总会朝地上落下去的。”李彦平解释说:“现在我们离地球太远了,感觉不到地球的拉力,所以我们感觉好像没有地球引力了。当我们更接近月球时,就会感到月球的引力在拉我们。但是,月球的引力不像地球的引力那么大。” 我立刻感到很高兴,由于失重我在太空舱里飘来飘去,我望着(身后的)地球越来越小,而(前方的)月球越来越大。 When we got there, I wanted to explore immediately, “Come on,” I said. “If you are right, my weight will be less than on the earth because the moon is smaller and I will be able to move more freely. I might even grow taller if I stay here long enough. I shall certainly weigh less!” I laughed (1)People all cheered up immediately when they saw the total solar eclipse.人们看到全日食后立刻高兴起来。 (2)Cheer up! I’m sure you’ll feel better tomorrow. 振作起来!我肯定你明天会好些的。 (3)Do something interesting to cheer yourself up. 做些有趣的事情让自己高兴起来。 4. now that由于;既然,引导原因状语从句,有时that可以省略。 (1)Now that I have nothing to do, I can enjoy music for a little while.既然我无事可做,我可以享受一会儿音乐了。 (2)Now you have grown up, you can make up your mind by yourself.你已长大了,可以自己作决定了。 (3)Now that you have got a chance, you might as well make full use of it.既然你得到了机会,你就应充分利用它。 [易混辨析]because, since, as, for与now that because 语气最强,一般指事情发生的直接原因,回答提问时,一般放在主句之后。 since 语气较弱,指双方都明确的原因或众所周知的原因,侧重主句,从句表示显然的或已知的理由。 and climbed down the steps from the spaceship. But when I tried to step forward, I found I was carried twice as far as on the earth and fell over. “Oh dear,” I cried, “walking does need a bit of practice now that④ gravity has changed.” After a while I got the hang of it and we began to enjoy ourselves. 我们到达月球时,我就想立即进行探测。“来吧,”我说,“要是你讲得对,我的重量就会比在地球上小,因为月亮比地球小,而我就能更自由地活动了。如果我在月球上呆的时间足够长的话,我甚至可能长得更高,我的体重肯定也会变得更轻!”我笑着从飞船的梯级上爬下来。而当我试着向前迈步的时候,我发觉我被送出去很远,步子的跨度竟是在地球上的两倍,因而我摔倒了。“天哪,”我大声说,“重力改变了,看来走路也的确需要练一练了。”过了一会儿,我才掌握了走路的诀窍,这才开始感到自如了。 Leaving the moon’s gravity was not as painful as leaving the earth’s. But returning to the earth was very frightening. We watched, amazed as as语气比because弱,所引导的从句表示的是显而易见的原因和理由,从句一般放在主句前。 for是并列连词,表示推断的原因,或对前一分句补充说明理由。 now that同since相似,语气较弱,强调人们已知的事实。 We couldn’t go out because it was too cold. 因为天气太冷,我们不能外出。 (4)Since you can’t answer the question, I’ll ask someone else.既然你回答不出这个问题,我就问别人了。 (5)It must be morning for the birds are singing.一定是清晨了,因为鸟儿在叫。 (6)As there was no answer, wrote him again. 鉴于他没有回复,我们又给他写了封信。 [典型例题] —Why didn’t you return Fred’s call? —I didn’t need to ____ I’ll see him tomorrow. 【点拨】because 回答why引导的问句要用because。 5.break fire broke out⑤ on the outside of the spaceship as the earth’s gravity increased. Again we were pushed hard into our seats as we came back to land. “That was very exhausting but very exciting too,” I said, “Now I know much more about gravity! Do you think we could visit some stars next time?” “Of course,” he smiled, “which star would you like to go to?” 摆脱月球引力不像摆脱地球引力那样痛苦;但是返回到地球的经历是非常吓人的。我们惊奇地看着,随着地球引力的增加,宇宙飞船的外层燃烧起火。当我们回到地面时,我们又感到被重重地推倒在座位上。我说道:“真是精疲力竭了,但也很激动人心。关于引力,我现在就懂得更多了。你认为下次我们可以上星球上去参观吗?”“当然可以,”他笑着说,“你想到哪颗星球上去呢?” out是固定短语,表示战争、火灾等的“爆发”,不能用于被动语态。 (1)A huge forest fire broke out after the lightning struck. 闪电打下来之后,突然引起一场森林大火。 (2)When the war broke out, the two countries broke off their diplomatic relations. 战争爆发后,两国间断绝了外交关系。 (3)If a war broke out, many other countries will be affected. 一旦战争爆发,许多国家都要受到波及。 [拓展] break up 解散;打碎 break down坏了;累垮了 break into闯入 break through突破 break away from脱离 break in打断谈话 [典型例题] I was still sleeping when the fire broke ____, and then it spread quickly. 【点拨】out 根据fire判断,要填out,break out爆发。 6.watch out当心;提放,后接名词时要加for。 (1)Watch out for cars when you cross the road. 过马路时当心车辆! (2)I advised them to watch out for slick spots on the sidewalk. 我叫他们当心人行道上路滑的地方。 (3)We have to watch out for fast traffic along here. 这里来往的车辆开得很快,我们必须小心。 [拓展] watch over监视;看守 on watch值班 on the watch留意;提防着 [典型例题] The building around the comer caught fire last night. The police are now watching _____the matter. 【点拨】over watch over监视。 Reading中长难句 1. “We are too far from the earth now to feel its pull,” he explained, “so we feel as if there is no gravity at all. a) too…to…太……而不…… Some of the stars are too far away for us to reach. 有些星球太远了,我们根本到达不了。 The stars in the sky are too many to count. 天上的行星太多了,数不过来。 b) as if好像;好似,引导表语从句或方式状语从句。 It looks as if it is going to rain. 看上去要下雨了。 In a spaceship, an astronaut feels as if he were floating in the air. 在宇宙飞船中,宇航员感觉就像在空中飘飘浮一样。 2. As the rocket rose into the air, we were pushed back into our seats because we were trying to escape the pull of the earth’s gravity. a)该句是一个含有时间状语从句的复合句,在主句中有一个because引导的原因状语从句。 b) as在此意为“随着;伴随着”。 As he grew older, he began to know more and more about the universe. 随着他的长大,他对宇宙里阿杰的越来越多。 As the plane was taking off, I felt as if my hearts would jump out of my mouth. 随着飞机起飞,我感到心要从嘴里跳出来。 3. I cheered up immediately and floated weightlessly around in our spaceship cabin watching the earth become smaller and the moon larger. watching the earth…是动词-ing形式构成的短语,在句中做伴随状语。 The boy lay on the ground, watching the stars in the sky. 小孩躺在那里,看着天上的星星。 The students sat quietly in the classroom, listening to the teaching explaining how life began. 学生们静静地坐着,听老师讲生命的起源。 [典型例题] Lots of rescue workers were working around the clock, (send)supplies to the flooded areas. 【点拨】sending send和workers有逻辑上的主谓关系,所以用动词-ing形式作状语。 Read the passage carefully and then describe the three ways in which gravity changed for Li Yanping and how his weight changed. 阅读短文,然后描述王艳平经历的地心引力改变的三种方式和他体重的变化。 Speaking and writing 口语和写作 1.

Music is nice, people seem to say, but not important. Too often it is viewed as mere entertainment, but certainly not an education priority(优先). This view is shortsighted. In fact, music education is beneficial and important for all students. ……………………………………………………………………………………………… ……………………………………………………………………………………………… The arts are forms of thought as powerful in what they communicate as mathematical and scientific symbols. They are ways we human beings “talk” to each other. They are the language of civilization through which we express our fears, our curiosities, our hungers, our discoveries, our hopes. The arts are ways we give form to our ideas and imagination so that they can be shared with others. When we do not give children access to an important way of expressing themselves such as music, we take away from them the meanings that music expresses. Science and technology do not tell us what it means to be human. The arts do. Music is an important way we express human suffering, celebration, the meaning and value of peace and love. So music education is far more necessary than people seem to realize. 70. According to the passage, the arts and science . A. approach the world from different angles B. explore different phenomena of the world C express people’s feelings in different ways D. explain what it means to be human differently [答案] A。本题属于间接信息题,需要根据文章中出现的信息综合考虑。文章的第四段中谈到“艺术是我们人类相互’交谈’的语言,是我们表达恐惧、好奇、饥饿、 发现、希望的文明语言等”,由此可以看出,人们通过艺术来展现整个世界,也就是说“艺术让我们从不同的角度来了解这个世界”。 2. 满分作文赏析 国际文化交流中心将组织一次由各国学生参加的“和平 · 友谊”夏令营活动,要求报名者提交英文个人简介。假设你是王姗,请根据下列信息写一篇个人简介。 注意: ( l )词数不少于 120。 ( 2)可根据内容要点适当增加细节,以使行文连贯。范文:I am a 16-year-old girl by the name of Wang Shan, and I’m currently studying in Beijing Sunshine Middle School.

An eclipse occurs in one of two ways: when the moon passes between the earth and the sun so that all or part of the sun cannot be seen for a time, or when the earth passes between the moon and the sun so that you cannot see all or part of the moon for a time. The first case is a solar eclipse or eclipse of the sun, which occurs as the earth enters the shadow of the moon. The second describes a lunar eclipse or eclipse of the moon, which happens when the moon enters the shadow of the earth. More than 60 percent of Nigerians are uneducated, and eclipses in some parts of the country in the past have caused commotions in which people have been killed and property destroyed. Some Nigerians believe an eclipse is punishment from the gods for evil doing. The March 29th eclipse would be the fifth in Nigeria’s history, and it is expected to last for 30 minutes — 9:15AM to 9:45AM, according to the official prediction. Nigeria witnessed eclipses in 1898, 1947, 1959, and 2001. The shadows in an eclipse have a central dark part called umbra, and a less dark external section called penumbra. In the umbra, all the sun’s light is cut off, and this is called total eclipse; while in the penumbra, only a part of the light from the sun is cut off from the moon, and it is called partial eclipse. Five Nigerian states — Oyo, Kwara, Niger, Zamfara, and Katsina — are expected to have total eclipse, while other parts of the country will experience partial eclipse. 21. This passage is mainly written to ________. A. predict a eclipse of the sun in Nigeria B. compare a eclipse of the sun with a eclipse of the moon C. provide information on a coming eclipse of the sun in Nigeria D. show that people in Nigeria receive little education 22. What does the underlined word “commotions” mean? A. Surprises. B. Disorders. C. Wars. D. Worries. 23. If this passage is taken from a newspaper, which section is the passage probably from? A. Entertainment. B. Economy. C. Education. D. Science. 24. The best title for this passage is ________. A. What Is an Eclipse B. How Foolish People in Nigeria Are C. Nigeria Expects Solar Eclipse D. Solar Eclipse Happens on March 29 B When people want to know about the weather, they usually go to there radios, TVs, newspapers, or to the Internet. However, you can also find many weather signs among wildlife, because of their highly developed senses. Drops in air pressure(压力) produce an effect on small animals in many ways. Mice and deer are good weather indicators. People who spend a lot of time outdoors have observed that, before a storm, field mice come out of their holes and run around, Deer leave high ground and come down from the mountains. Birds are especially good weather indicators because they also show the effect of a pressure drop in many ways. For example, some birds become irritable(急躁的)and quarrelsome and will fight over a piece of bread. Other birds chirp (叽叽喳喳) and sing just before a storm. It seems they know they won’t get another chance for an hour on two. Birds also seek safe places before a storm. You will sometimes see birds settling in trees or gathering together on a wire close to a building. Pre-storm low pressure makes the air so thin that birds have difficulty flying. It is unusual to see many birds flying overhead in the summertime, rather than during the periods in the spring or autumn. Watch for other weather signs if you see this. If they fly in the wrong direction, they may be flying ahead of a storm. By paying closer attention to some important signs in nature, we can become better prepared for any kind of weather. 25. The word “indicators” in paragraph I probably means . A. maps B. services C. signs D. stations 26. There will be a storm if birds . A. make more noise than usual B. fly in different directions C. come down from tall trees D. share a piece of bread 27. How can birds sense the coming of a storm? A. By feeling a drop in air temperature. B. By noticing the change of wind directions. C. By feeling a drop in air pressure. D. By noticing the movements of other animals. 28. The best title for the text would be . A. Signs of a Storm B. Drops in Air Pressure C. Animals’ Sharp Senses D. Nature’s Weather Signs C In June, 2010, a group of students from eight high schools in Winnipeg, the capital of Canada’s Manitoba province, will begin test-launching(试发射) a satellite the size of a Rubik’s cube. The one-kilogram Win-Cub satellite, named for its home city and its shape, will be put into low orbit. Once in space, it can perform for a few months or up to several years, communicating information that could help find the signs of earthquakes. There are 80 similar satellite projects worldwide, but this is the first high-school based program of its kind in Canada.30 Manitoba high school students are having a hand in designing and building the satellite, in cooperation with aerospace(航空航天的) experts and 10 students from the University of Manitoba, and with support from two other organizations. The Win-Cube project is not something that goes on a piece of paper; it is real-world engineering, allowing high school students to have an opportunity to learn more about the exciting world of engineering through their participation in this challenging program. It is also taken as a wonderful example of the unique partnerships within Manitoba. Designing, building and launching a satellite with high-school participation will bring this world-class educational project into reality and Manitoba closer to space. “These Manitoba high school students deserve congratulations for their enthusiasm, innovation(创新), and a strong love for discovery,” said Education, Citizenship and Youth Minister Peter Bjomson. “We want to make science more relevant, interesting and attractive to high school students by showing them how classroom studies can relate to practical experience in the workplace or, in this case, in space,” Bjomson added. The Win-Cube program is mainly named at inspiring a strong desire for discovery on the part of the students. It also shows Manitoba’s devotion to research and innovation and the development of a skilled workforce—all important drivers of knowledge-based economic growth. 29. According to the passage, the Win-Cube satellite is _________. A.named after Manitoba and its shape B.intended for international communication C.designed like a Rubik’s cube both in shape and size D.challenged by university students around the world 30. According to Mr. Bjomson, ___________. A.those Manitoba high school students are worth praising B.the study of space can be practically made in classrooms C.Manitoba high schools are famous for the study of space D.scientific research is too far away from high school students 31. The primary purpose of the project is to _________. A.find the early signs of earthquakes B.relate studies to practical C.help high school students study real-world engineering D.inspire a strong desire for discovery among the students 32. The best title for this passage may be ________. A.Manitoba School B.Win-Cube Program C.Space Co-operation D.Satellite Launching D Discover Newsmagazine of science devoted to the wonders an stories of modern science, written for the educated general reader.

After Tereshkova’s landmark mission, it would take another 20 years for the United States to send a woman into space. 38 Since then, a total of 57 women from nine different countries have blasted off. Chinese astronaut Wang Yaping heads for the launch site shortly before her mission to dock with a space lab on June 11. 39 NASA astronaut Karen Nyberg was aboard the International Space Station and China sent its second-ever female astronaut, Wang Yaping, to work on its orbiting space module. However, Tereshkova remained the only woman to complete a solo flight. In recent years, NASA has run into trouble with funding. 40 However, this new class of astronaut candidates suggests that NASA is looking ahead to the future of space exploration. The group includes the first female fighter pilot to become an astronaut in almost two decades, as well as a female helicopter pilot. A. Since then, many astronauts have conquered the space. B. Two women have been in orbit in recent years. C. However, her parents thought it dangerous to do so and tried to stop her. D. Currently, there are no American spacecraft that can carry humans to space. E. Astronaut Sally Ride became the first female American woman to leave Earth on June 18, 1983. F. Two years later another Russian cosmonaut, Yuri Gagarin, achieved the first piloted spaceflight in 1961. G.

C 主旨大意题。根据文章的第一句“About five states in Nigeria will experience a total eclipse (日蚀) of the sun on March 29”可知,该文主要介绍的是即将在尼日利亚发生的日食。 37. B 词义猜测题。根据下文的“people have been killed and property destroyed”可知,该词的意思是“动荡;骚扰”,所以选B。 38. D 推理判断题。文中很明确地介绍了日蚀是怎样发生的,以及日全食与日偏食的原因等,所以本文涉及的是日食方面的科普知识,故选D。 39. C 主旨大意题。该文主要介绍的是即将在尼日利亚发生的日食。所以用C项作标题准确反映了本文的主题内容。 B 【语篇解读】人们能从许多小动物的身上看到天气变化的迹象,因为气压的变化在许多方面对动物有影响。 40. C 词义猜测题。根据you can also find many weather signs among wildlife推测,该词指的就是signs。 41.

D 细节理解题。根据named at inspiring a strong desire for discovery on the part of the students可知,该项目的目的是为了及其学生发现的欲望,所以选D。 47.
