Naturally I was curious, so I went towards the truck when I noticed that there was a small_little_goat that wasn't even an adult yet. I asked my dad and he said that he bought the goat from his friend and decided to mention that he was going to kill it twenty minutes after he brought it home so that we would have_a_big_meal. My sister was there too and she was strongly for my view. We found_out we got really mad at my dad and told him not to kill it. After about 10 minutes of complaining we finally convinced my dad not to kill it because we told him that there was no reason for him to kill the goat himself when he could just buy goat meat at a store. My parents know some friends that we visit sometimes and their family really likes animals so we decided to give it to them. For about a month, they had the goat as a pet and they also had the same problems we had because the dad wanted to kill it and eat it but the rest of the family didn't want it to die. They also were able to persuade him not to do so. They ended up sending the goat to a family member's farm where it would grow up happily. Another thing that has happened to influence my belief is that I have a neighbor that really likes hunting. One day he hunted a deer and brought the body home, but he decided to leave it outside his house for everyone to see. He just left it there as if it were some kind of award that he just won. Sadly little kids started to make fun of the body and pretended to ride on it. They laughed at it and felt no_problem with there being a dead deer just laying there. 注意:1.所续写短文的词数应为150左右; 2.至少使用5个短文中标有下划线的关键词语; 3.续写部分分为两段,每段的开头语已为你写好; 4.续写完成后,请用下划线标出你所使用的关键词语。 Paragraph 1: I felt sick by what was happening and left because of what I had just witnessed. Paragraph 2: It amazes me how we have changed from hunting to survive to hunting for sport. [写作步骤] 第一步:速读全文 文本大意:作者一直认为将猎捕来的动物作为食物是不可取的,并且在家中经历了小羊的事件之后,作者从中得到了更多。 叙述意图:文章告诉我们要保护好自然界中的每个生灵。呼吁人们从我做起,保护动物。 第二步:细读全文 1.所给短文情景模式分析。 who I, my dad, my sister, a neighbor, little kids what My dad wanted to kill a small little goat and we persuaded him not to do so. A neighbor hunted a deer and brought the body home. when one day where at home why There was no reason for him to kill the goat himself when he could just buy goat meat at a store. 2.对原文所提供的下划线词语进行分类。 ★人物/动物:small little goat, animal, neighbor ★事件:have a big meal ★动作与心理描写:kill, find out, hunt, award, fun, no problem 第三步:精心谋篇 1.Paragraph 1:I felt sick by what was happening and left because of what I had just witnessed. 我对所发生的一切感到恶心,并因我刚刚目睹的一切而离开。 [情节分析] 从续写段首句及所给短文的结尾部分可知,故事要围绕作者对于虐待动物的厌恶情绪写起;同时也要考虑与下一段的衔接,即为了好玩而狩猎。 2.Paragraph 2:It amazes me how we have changed from hunting to survive to hunting for sport. 让我惊讶的是,我们是如何从为生存狩猎到为好玩而狩猎的。 [情节分析] 注意关键词hunting for sport,再根据所给短文中提到的作者保护动物的做法看,作者对于“hunting for sport”是持反对态度的。这里会呈现反对的理由:猎杀动物会造成动物灭绝;不要以为杀死一只动物就没有错。最后是呼吁人们从我做起,保护动物。 第四步:初写成文 Paragraph 1: 1.那里的大多数人看不出刚才发生的事情有什么问题。 The_majority_of the people there saw no problem with what was happening. 2.他们不认为自己做错了,也不应该为此受责备。 They didn't think they were doing wrong and that they were to_blame_for that. 3.一个月后,我发现邻居的女儿当长大时想去打猎,因为她觉得这很“有趣”,这使我很烦恼。 A month later, I found out that my neighbors' daughter wanted to hunt when_she_got_older because she thought it was “fun”, and this bothered me greatly. Paragraph 2: 4.我只是觉得没有任何理由为了好玩而杀死一个动物。 I just don't think there is any reason to kill a living thing for_fun. 5.这只会导致人们猎杀动物,甚至小山羊也会濒临灭绝。 This just leads to people hunting_animals,_and even the small little goat is endangered. 6.人们开始认为,只要不是人,杀死一条生命就没有错。 People start to think that there's nothing wrong with killing a life as_long_as_it's_not_a_human. 7.如果我请求你做一件事,那就是对动物持开明的态度,而不仅仅是对人类。 If there's one thing I ask you to do, it's to be_openminded_towards animals not just humans. 8.不要为了好玩而杀害动物。 Don't kill for_sport. 第五步:润色升级 1.用定语从句改写要点3。 A_month_later,_I_found_out_that_my_neighbors'_daughter_wanted_to_hunt_when_she_got_older_because_she_thought_it_was_“fun”,_which_bothered_me_greatly. 2.用because合并要点5和要点6。 This_just_leads_to_people_hunting_animals,_and_even_the_small_little_goat_is_endangered_because_people_start_to_think_that_there's_nothing_wrong_with_killing_a_life_as_long_as_it's_not_a_human. 3.用高级词汇替换要点7中的ask。 ask→beg 第六步:复查定稿 Paragraph 1: I felt sick by what was happening and left because of what I had just witnessed. The majority of the people there saw no_problem with what was happening. They didn't think they were doing wrong and that they were to blame for that. A month later, I found_out that my neighbors' daughter wanted to hunt when she got older because she thought it was “fun”, which bothered me greatly. Paragraph 2: It amazes me how we have changed from hunting to survive to hunting for sport. I just don't think there is any reason to kill a living thing for fun. This just leads to people hunting animals,_and even the small_little_goat is endangered because people start to think that there's nothing wrong with killing a life as long as it's not a human. If there's one thing I beg you to do, it's to be openminded towards animals not just humans and don't kill for sport. 一、复现单元考点——增强备考信心 Ⅰ.高考中的语法填空 1.(2018·全国卷Ⅰ)Ten years after my chess class with Ashley, I'm still putting to use what he taught me: The absolute (absolutely)most important skill that you learn when you play chess is how to make good decisions. 2.(2017·浙江高考)Alia Baker is a librarian in Iraq.

This map shows the chances of an earthquake in each part of the country. The areas of the map where earthquakes are most likely to occur are called earthquake belts. The government is spending a great deal of money and is working hard to help to discover the answers to these two questions: [2]Can we predict earthquakes? [3]Can we control earthquakes? [4]To answer the first question, scientists are looking very closely at the most active fault (断层) systems in the country, such as the San Andreas fault in California. A fault is a break between two sections of the earth's surface. These breaks between sections are the places where earthquakes occur. Scientists look at the faults for changes which might show that an earthquake was about to occur. But it will probably be many years before we can predict earthquakes correctly. And the control of earthquakes is even farther away. [5]However, there have been some interesting developments in the field of controlling earthquakes. The most interesting development concerns the Rocky Mountain Arsenal earthquakes. Here water was put into a layer of rocks 4,000 metres below the surface of the ground.Shortly after this injection (注射) of water, there was a small number of earthquakes. Scientists have decided that the water which was injected into the rocks worked like oil on each other. [6]When the water “oiled” the fault, the fault became slippery and the energy of an earthquake was given out. Scientists are still experimenting at the site of these earthquakes. They have realized that there is a connection between the injection of the water and the earthquake activity. They have suggested that it might be possible to use this knowledge to prevent very big, dangerous earthquakes, that is, scientists could inject some kind of fluid like water into faults and change one big earthquake into a number of small, harmless earthquakes. 语篇解读:为了提高人们对地震的防范意识,美国政府加大了在防震、预测方面的投入,他们甚至在努力采取措施控制地震的发生。 1.Earthquakes belts are_________. A.maps that show where earthquakes are likely to occur B.zones with a high probability of earthquakes C.breaks between two sections of the earth's surface D.the two layers of earth along a fault 解析:选B 细节理解题。根据第一段的第三句可知,地震多发地带被称为earthquake belts。 2.The San Andreas fault is_________. A.an active fault system B.a place where earthquakes have been predicted correctly C.a place where earthquakes have been controlled D.at the foot of the Rocky Mountain 解析:选A 细节理解题。根据第四段首句可知,该断层是比较活跃的断层系统。 3.What did scientists learn about earthquakes at the Rocky Mountain Arsenal? A.They occur at about 4,000 metres below ground level. B.The injection of water into earthquake faults prevents earthquakes from occurring. C.They are usually caused by the oil in the faults. D.Harmful earthquakes could be prevented by causing harmless earthquakes. 解析:选D 细节理解题。根据最后一段尾句可知,科学家通过向断层注入水之类的液体可以把危害的地震转变成若干个无害的地震。 4.What can be said about the experiments at the Rocky Mountain Arsenal? A.They have no practical value in earthquake prevention. B.They may have practical value in earthquake prevention. C.They are certain to have practical value in earthquake prevention. D.Nothing is told about their practical value in earthquake prevention. 解析:选B 推理判断题。根据科学家的试验,通过向断裂带注水可以引发小地震,从而使地震的能量得到释放,因此也就降低了大地震爆发的可能。 学习目标 ——题后把脉规律,练后得法理解更透 细节理解技法(8)——两步攻克事实询问题 事实询问题,这类试题通常以疑问词what/who/when/where/why/how引导的特殊疑问句,就文章中某一词语、某一句子、某一段落或某一具体细节和事实进行提问。 解答此类试题的两个步骤:(1)首先要弄清题目和每一个选项的含义;(2)然后按题目要求寻找与之相关的细节,正确估计答案来源。同时要注意题目和文章中的暗示。 例如上文第3小题,根据文章最后一段的表述,可知D项符合题意。查看更多
