单元检测第一部分听力(略)第二部分阅读理解(共两节，满分40分)第一节(共15小题；每小题2分，满分30分)阅读下面短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。
AWith around 100 students scheduled to be in that 9：00 am Monday morning lecture，it is no surprise that almost 20 people actually make it to the class and only 10 of them are still awake after the first 15 minutes；it is not even a surprise that most of them are still in their pyjamas(睡衣)．Obviously，students are terrible at adjusting their sleep cycles to their daily schedule.All human beings possess a body clock.Along with other alerting(警报) systems，this governs the sleep/wake cycle and is therefore one of the main processes which govern sleep behaviour.Typically，the preferred sleep/wake cycle is delayed in adolescents，which leads to many students not feeling sleepy until much later in the evenings.This typical sleep pattern is usually referred to as the “night owl” schedule of sleep.This is opposed to the “early bird” schedule，and is a kind of disorder where the individual tends to stay up much past midnight.Such a person has great difficulty in waking up in the mornings.Research suggests that night owls feel most alert and function best in the evenings and at night.Research findings have shown that about 20 percent of people can be classified as “night owls” and only 10 percent can be classified as “early birds”—the other 70 percent are in the middle.Although this is clearly not true for all students，for the ones who are true night owls this gives them an excellent excuse for missing their lectures which unfortunately fall before midday.21．What does the author stress in Paragraph 1?A．Many students are absent from class.B．Students are very tired on Monday mornings.C．Students do not adjust their sleep patterns well.D．Students are not well prepared for class on Mondays.答案 C解析细节理解题。

课时作业(二十六)题型组合练——练规范(阅读理解＋语法填空＋短文改错＋书面表达)限时：55分钟Ⅰ.阅读理解A“De-extinction”，the idea that extinct (绝种的) animals can be brought back through cloning or genetic (基因的) engineering，has attracted the interest of a small group of scientists. The topic has made the cover of National Geographic Magazine. Supporters say they are doing it for moral reasons and because we “miss” the extinct animals. They blame human exploitation (such as trapping，hunting, habitat destruction ) of the extinct animals, but their plans, though they sound exciting, are exploitation in another form.Considering the imperfect science of cloning, de-extinction would cause animals suffering. Most animals born of such experiments would suffer serious diseases, dying soon after birth or having a shortened lifetime. Spanish and French scientists worked for years to bring the Pyrenean ibex, a species of wild goat, back from extinction by cloning. In 2009, they succeeded only in producing a sick baby goat that died 10 minutes after birth. For these animals to be born, other animals would live in captivity, in a lab or elsewhere, and serve as mother substitutes (代用品)，routinely having operations as part of the cloning process. For example, elephants would be kept in captivity to carry woolly mammoth (猛犸) babies for nearly two years. Such experiments often lead to other animals' unhappiness as well.If extinct animals are successfully brought back, where would they go? Their original habitats have developed and changed without them. They are unlikely to survive in the natural environment, but, if they do manage to survive, they will affect their environment in unpredictable ways, presenting a new threat to the ecological system. If the animals born through de-extinction are stuck in zoos and museums instead, what good is that? It is exploitation, not a solution.It would be better to apply creative thinking about protection to the real-life problems of today's world. De-extinction takes attention away from the difficult situation of endangered animals. Discussions about woolly mammoth cloning do nothing to stop the illegal killings of endangered wild African elephants. Money would be better used to prevent human conflict with wildlife and their ecosystems.Let's keep de-extinction in the world of science fiction, learn from our failed past, and protect wild animals and their habitats for the future.[语篇解读]本文为一篇议论文。

do，it作形式主语，符合题意，故填it．4．which．考查定语从句．根据句子结构分析，该句为非限制性定语从句，关系代词在从句中作makes的主语，故填which．5．various．考查形容词．根据句子结构分析，修饰名词用形容词，variety的形容词为various，故填various．6．a．考查冠词．由于谓语为is，所以此处用a，a

arriving at school， I discussed with some classmates that we could do． The next day， we got up early and preparing porridge at home． When we handed the cleaners the hot porridge and expressed us appreciation for their hard work， they looked a little surprisingat first． And then they took the porridge and thanked us happily．Since it was very cold，we all felt warm at that moment．解析：1．extreme→extremely．考查形容词与副词用法区别．形容词主要修饰名词，副词可修饰动词、形容词及副词．此处修饰形容词cold，应该用副词extremely．2．in→on．考查介词．in one's way表示"挡道，妨碍某人"．此处表示"在我去学校的路上"，应该用短语on my way to school．故将in改为on．3．cleaner→cleaners．考查名词的数．cleaner是可数名词，前面有two来修饰，应该用复数形式cleaners．4．去掉are．考查复合宾语．动词see后接复合宾语，see sb． doing看到某人在做某事．are是多余的，故去掉．5．在mind后加to．考查非谓语动词．make up one's mind 后面通常加动词不定式，即make up one's mind to do sth（下定决心要干某事），所以在mind后应加to．6．that→what．考查名词性从句的连接词．本句中从句作动词discuss的宾语，而连接词又在从句中作动词do的宾语，that在名词性从句中不承担句子成分，也没有实际意义，故将that改为what．7．preparing→prepared．考查动词形式．and连接两个并列的成分，前面 got up 是谓语动词，此处也应该是谓语动词．故将preparing改为动词的过去式prepared．8．us→our．考查代词．此处代词修饰名词 appreciation，应该用所有格形式，us是宾格，所有格是our．9．surprising→surprised．考查形容词．surprising（令人吃惊的、奇怪的），主要用来描述事或物本身所具有的性质或特征；surprised（惊奇的、感觉意外的）主要用来描述人的感受．此处描述清洁工的感受，应该用surprised．10．Since→Although/Though．考查从属连词．since当"既然、由于"讲，引导原因状语从句．此处为让步状语，应该用Although或Though．记叙文短文改错【解析】本文讲述了"我"和同学在寒冷的上早上为清洁工送热粥的故事．【解答】答案：It was extreme cold last Monday morning． While I was walking in my way to school，I noticed two street cleaner sweeping the street． Seeing them are working so hard on sucha cold morning， I was moved and made up my mind∧ do something for them． After arriving at school， I discussed with some classmates that we could do． The next day， we got up early and preparing porridge at home． When we handed the cleaners the hot porridge and expressed us appreciation for their hard work， they looked a little surprisingat first． And then they took the porridge and thanked us happily．Since it was very cold，we all felt warm at that moment．解析：1．extreme→extremely．考查形容词与副词用法区别．形容词主要修饰名词，副词可修饰动词、形容词及副词．此处修饰形容词cold，应该用副词extremely．2．in→on．考查介词．in one's way表示"挡道，妨碍某人"．此处表示"在我去学校的路上"，应该用短语on my way to school．故将in改为on．3．cleaner→cleaners．考查名词的数．cleaner是可数名词，前面有two来修饰，应该用复数形式cleaners．4．去掉are．考查复合宾语．动词see后接复合宾语，see sb． doing看到某人在做某事．are是多余的，故去掉．5．在mind后加to．考查非谓语动词．make up one's mind 后面通常加动词不定式，即make up one's mind to do sth（下定决心要干某事），所以在mind后应加to．6．that→what．考查名词性从句的连接词．本句中从句作动词discuss的宾语，而连接词又在从句中作动词do的宾语，that在名词性从句中不承担句子成分，也没有实际意义，故将that改为what．7．preparing→prepared．考查动词形式．and连接两个并列的成分，前面 got up 是谓语动词，此处也应该是谓语动词．故将preparing改为动词的过去式prepared．8．us→our．考查代词．此处代词修饰名词 appreciation，应该用所有格形式，us是宾格，所有格是our．9．surprising→surprised．考查形容词．surprising（令人吃惊的、奇怪的），主要用来描述事或物本身所具有的性质或特征；surprised（惊奇的、感觉意外的）主要用来描述人的感受．此处描述清洁工的感受，应该用surprised．10．Since→Although/Though．考查从属连词．since当"既然、由于"讲，引导原因状语从句．此处为让步状语，应该用Although或Though．Ⅵ.书面表达（满分25分）【答案】In recent years more and more high school students study abroad during the holidays．Studying abroad is beneficial to them．First of all，it will open their mind and enrich their experience．In addition，①it is a good chance to learn new cult ure and make new friends，②which can improve their communication skills（高分句型一）．However，it will take parents a lot of money to send their children abroad．And some students prefer traveling to learning．So it is a waste of money and absolutely not worthwhile．Personally，studying abroad can help students broaden their horizons and learn to be independent（高分句型二）．But I think it will be better for them to study abroad when they are old enough to support themselves financially（高分句型三）．开放类应用文阅读【解析】本文为议论文写作．人称以第一人称为主，时态为一般现在时．写作要点为：1．分析高中生出国游学的利弊；2．阐述你对此现象的看法．重要词汇：study abroad （出国留学）；be beneficial to（有益于）；in addition（另外，此外）；communication skills（交际能力，沟通能力）；prefer A to B（A与B相比，更喜欢A）；broaden ome's horizon（开阔某人的视野）； support（支持）高分句型：1．In addition，it is a good chance to learn new culture and make new friends，which can improve their communication skills．①it作形式主语，真正的主语为后面的不定式短语to learn new culture and make new friends；②which引导一个非限制性定语从句，关系代词which指代前一句中提到的事情．2．Personally，studying abroad can help students broaden their horizons and learn to be independent．非谓语动词studying abroad 在句中作主语．3．But I think it will be better for them to study abroad when they are old enough to support themselves financially．这句中用到了句式结构"it+be+（for sb）+to do sth"，其中it是形式主语，真正的主语是后面的不定式短语．【解答】In recent years more and more high school students study abroad during the holidays．Studying abroad is beneficial to them．First of all，it will open their mind and

Why not create a more ecofriendly house this year?

The 10 biggest energy users in your house are. Obviously, the best way to save energy is to buy new, energyefficient appliances.W2 Of course, this is not always practical. A few different tricks can still save you energy.Just switching out P1 your light bulbs can have an impact on P2 your home energy use. CFL Light Bulbs may be more expensive, but they last much longer and save 75 percent of the energy. If you have any air conditioner W3 window units that cannot be removed, try to cover the vents (排气孔), both inside and out. This will protect the unit and at the same time, remove any cold air that could be entering your home. This simple and almostcostfree solution is a great way to lowe r utility bills.Did you ever think that planting trees around your yard would help with energy efficiency? When the weather warms up, adding to P3 your landscaping is a beautiful way to cut energy for a relatively poorly insulated house. The leaves of trees, especially on the west side of your house, will block the sunlight that would warm your house, reducing the need for air conditioner.S During the winter, when tree branches are bare, more sunlight is let through, warming the house.Creating a more sustainable house is just one idea of how you can give back to our planet this year.
