Unfortunately，he couldn’t understand me but seemed very friendly.I showed him the room card with all the information of the Friendship Hotel in Chinese characters.He looked at it，and then his eyes moved quickly to the carriage subway map.Next，he raised three fingers of his right hand.‎ In Australia，raising fingers at someone is not usually nice，but this man wasn’t smiling.At the next station he showed me two fingers.Now in Australia，that’s really rude，but I got the message.When we stopped at the third station，he didn’t just point to the door，but got up，took me out of the train，and led me to the top of the stairs，and out onto the street.Then he stopped a taxi and told the driver where to take me.‎ All this came from a man who couldn’t speak my language，and I couldn’t speak his.I was now speechless，especially when he refused my offer of money.I felt a little embarrassed having even thought he would accept a tip.‎ This experience made it clear that I had to learn some Chinese quickly or my adventures might start turning into bad luck.‎ 语篇解读　作者讲述了自己在北京的一次冒险经历。‎ ‎24．The author decided to take the subway because .‎ A．he lived near the city center B．the network covered most of the stops C．he believed in his ability to deal with the trip D．he had a good impression of its cleanliness 答案　C 解析　细节理解题。根据第一段第一、二句可知，作者相信自己能处理好这次旅程。故选C。‎ ‎25．Having been shown the room card，the young man .‎ A．understood the author well B．still remained puzzled C．answered the author directly D．pointed at the subway map 答案　A 解析　推理判断题。根据第二段最后两句可知，年轻人看到房卡后就看车厢的地图，然后伸出三根手指头。说明年轻人已经知道作者的意思。故选A。‎ ‎26．Which of the following can NOT be used to describe the young man?‎ A．Helpful. B．Rude.‎ C．Warmhearted. D．Caring.‎ 答案　B 解析　推理判断题。根据文章内容可知，年轻人虽然不会说英语却亲自送作者出站，为他叫了出租车，并告诉出租车司机作者要去的地方，由此可判断选项A、C、D都是正确的。故选B。‎ ‎27．The author’s purpose of writing this passage is mainly to .‎ A．prove the importance of being careful B．appreciate the kindness of the young man C．complain some cultural misunderstanding D．describe one of his adventurous experiences 答案　D 解析　写作目的题。通过对整篇文章的理解可知，作者讲述了自己在北京的一次冒险经历。故选D。‎ C Next time you hear a funny joke you’d better not laugh too hard.According to a paper published by the British Medical Journal，laughter isn’t always the best medicine.Sometimes it can even be harmful.Professor Robin Ferner from the University of Birmingham，one of the authors of the study，found that bad things could happen to people who laughed too much.He says，“We found people with heartbeat problems which had stopped their hearts，we found people who had fainted(昏倒)，and we found people who’d dislocated their jaws or burst their lungs.”‎ It seems that laughing can be no laughing matter.But it’s not all doom and gloom.Professor Ferner says there are benefits to laughing when you want to lose weight，for example.Yes，that’s right: laugh and be slimmer! Professor Ferner explains that，“You use energy when you laugh，you move your diaphragm(横隔膜)，you expand your lungs，and both those things can be helpful.”‎ According to the research，laughing for a quarter of an hour can burn 40 calories，and if you laughed all day you’d use up about 2,000 calories，which is what most people consume in a day.But don’t do that or you might end up with a painful jaw.Ouch! Or ‎ you might find people looking at you in a funny way.‎ But I don’t want to finish this article leaving you feeling desperate.Laughter comes naturally for most of us.Babies begin to laugh at around 3－6 months.So give in to your sense of humour and keep smiling.Life is short anyway.‎ 语篇解读　笑对人有益吗？有的认为有好处，有的认为没有好处。‎ ‎28．Laughing too much may cause the following harmful results EXCEPT .‎ A．heart stop B．diaphragm movement C．lung burst D．jaw dislocation 答案　B 解析　细节理解题。根据第一段最后一句“He says，‘We found people with heartbeat problems which had stopped their hearts，we found people who had fainted(昏倒)，and we found people who’d dislocated their jaws or burst their lungs.’”可知，笑得太多的危害性有：心脏骤停、昏倒、下巴脱臼以及伤到肺。B项没有提到。‎ ‎29．The underlined phrase “doom and gloom” in Paragraph 2 probably means “ ”．‎ A．hopeless B．funny C．painful D．nervous 答案　A 解析　词义猜测题。根据第二段提到“好像笑并不是玩笑的事情，但它也不是无用，费尔纳教授说，当你想减肥时，笑是非常有效的”。故选A项。‎ ‎30．How many calories can you use if you laugh for half a day?‎ A．About 40. B．About 1,000.‎ C．About 2,000. D．About 2,040.‎ 答案　B 解析　数字计算题。根据第三段提到“if you laughed all day you’d use up about 2,000 calories，which is what most people consume in a day”可知，一天消耗大约2 000卡路里，那么半天就消耗大约1 000卡路里。故选B项。‎ ‎31．What is the author’s attitude towards laughing in the last paragraph?‎ A．Uninterested. B．Disapproving.‎ C．Worried. D．Favorable.‎ 答案　D 解析　观点态度题。根据最后一段提到“So give in to your sense of humour and keep smiling.Life is short anyway.”可知，作者认为不要放弃幽默，保持微笑，毕竟生命是短暂的。故选D项。‎ D Soccer is not a violent game.But players can hit the ball with their heads to purposely change the direction of the ball.In the sport，this move is known as a “header”．Besides，they may sometimes collide(碰撞) with other players，the ground and goal posts(门柱)． ‎ Catherine McGill is an expert at the Children’s National Health System in Washington，D.C.She examines many children who have suffered concussions(脑震荡)．Concussions are the most common brain injury when children are playing soccer.Her research shows that concussions from soccer and other youth sports are increasing these days.‎ Catherine McGill says，“On the one hand，we are getting better.That means parents，coaches and medical providers are getting better at recognizing and responding to that injury.They are paying more attention to the safety of their children.On the other hand，kids are getting bigger，faster，and stronger across the sports，so more injuries will happen simply because of that.”‎ Catherine McGill spoke at a recent meeting on ways to make soccer safer for young players.The meeting was held recently in Washington，D.C.She said，“Researchers are examining the influences of soccerrelated head injuries.They want to know whether repeated hits to the head can cause CTE.” CTE is a brain disease which will become worse and worse as a person ages.‎ She said she was often asked by parents about at what age children should start “heading” or whether there should be “heading” at all.She thinks that this is a very individual decision.The age for one child may be very different from the age for another.‎ 语篇解读　研究发现用头击球可能会引起头部受伤。‎ ‎32．We can learn from the first two paragraphs that playing soccer .‎ A．needs many different skills B．belongs to a very violent game C．may cause brain injuries to children D．is not good for little children 答案　C 解析　细节理解题。根据文章前两段内容可知，孩子们在踢足球的时候常常用头顶球，还可能和别人发生碰撞，这些都可能导致孩子们的脑部受伤。‎ ‎33．The underlined word “that” in Paragraph 3 means “ ”．‎ A．more and more children enjoy playing sports B．young players are becoming stronger and faster C．parents pay more attention to their children’s safety D．teachers protect children from suffering brain injuries 答案　B 解析　代词指代题。根据画线词所在的上文可知，因为孩子越来越高大、强壮，跑得也越来越快了，因此踢球时更容易发生碰撞而导致脑损伤。‎ ‎34．In Catherine’s opinion，kids should start “heading” .‎ A．according to their own situations B．when they are stronger C．from an early age D．when they are faster 答案　A 解析　推理判断题。根据最后一段最后两句“She thinks that this is a very individual ‎ decision.The age for one child may be very different from the age for another.”可知，由于每个人的情况不同，因此凯瑟琳建议孩子根据自己的情况来决定是否用头击球。‎ ‎35．What is the main idea of this passage?‎ A．How to make soccer safer for children.‎ B．Why more children choose to play soccer.‎ C．“Heading” is harmful to children who play soccer.‎ D．The advantages and disadvantages of playing soccer.‎ 答案　C 解析　主旨大意题。文章主要介绍专家的研究发现：孩子们踢足球的时候用头顶球可能会给他们的头部带来伤害。‎ 第二节　(共5小题；每小题2分，满分10分)‎ 根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。‎ People have always wanted to know what the future will look like.Then，how can we know what the future will look like？ 36 The world has changed a lot in the past 150 years，but we humans are driven by the same basic needs as we were 150 years ago，such as food，sleep，the feeling of being appreciated and loved.‎ ‎ 37 No.In addition，generally speaking，the inventions for the last 150 years have been a human effort for freedom and communication，to be able to get in control of the time and world.Since there is still much to do in this area，this will be the focus at least for the next 150 years.‎ But why do we need to predict the future？Predicting the future is important for two reasons：first we need to start to think about what kind of future we’d like for ourselves and to pass on the next generation. 38 ‎ How about the virtual worlds？It might be possible in the future to experience the sand between your toes，and hear the waves，just lying in your bed at home. 39 So，even if a great invention is there for an affordable price，it’ll never take the place of the common experience if it’s not real.‎ ‎ 40 What we’ll see in the next 50 years is the transition from an oildependent society to a new society.Here there’ll be new medicine，continued exploration of space，challenges in the climate change，and new inventions that make life a little easier.‎ A．So what will the future look like then?‎ B．Will this change in the next 150 years?‎ C．Predicting the future can help us in many ways.‎ D．However，you’ll never get the feeling of being there.‎ E．Well，to understand the future，you must know the past.‎ F．However，no matter how real the experience will feel，it doesn’t happen for real.‎ G．Then we need to know what decisions we need to make today that will give the best result in the future.‎ 语篇解读　人们总是好奇我们的未来会是什么样，本文作者向我们展示了我们预测未来的原因及未来50年有可能会发生的变化。‎ ‎36．答案　E 解析　根据第一段中空格前的句子“Then，how can we know what the future will look like？”和空格后的句子“The world has changed a lot in the past 150 years...”可知空格处讲的是过去和未来的关系，所以E项(为了更好地理解未来，我们必须知道过去)符合语境。‎ ‎37．答案　B 解析　根据空后的“No.”可知此处应该为一般疑问句，又根据本段的意思可知空格处的意思是：在接下来的150年，这些会改变吗？故选B。‎ ‎38．答案　G 解析　根据本段中“Predicting the future is important for two reasons：first we need to start to think about...”可知，空格处应该是第二个原因，故用then来引出句子，即然后我们需要知道今天需要做什么样的决定，会给未来带来最好的结果，故选G。‎ ‎39．答案　F 解析　根据空格前句可知躺在家里的床上感受到的一切再真实也不是现实，因为现实中没有发生这样的事情，故选F。‎ ‎40．答案　A 解析　本段主要谈论了未来会是什么样子。根据空格后的“What we’ll see in the next 50 years is the transition from an oildependent society to a new society.”可知选A。‎
