单元测评(三)Unit 3Under the sea(时间：90分钟满分：110分)第一部分阅读理解(共两节；满分30分)第一节(共10小题；每小题2分，满分20分)阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。AIf you travel to a new exhibit at the San Francisco Greenhouse of Flowers, you will have a chance to see some meateating plants. Take bladderworts, a kind of such plant, for example. They appear so small and grow in a quiet pool. But these are the fastestknown killers of the plant kingdom, able to catch a small insect in 1/50 of a second using a trap (陷阱) door!Once the trap door closes on the animal falling into it, the enzymes (酶) similar to those in the human stomach slowly digest the insect. When dinner is over, the plant opens the trap door and is ready for trap again.Meateating plants grow mostly in wet areas with soil that doesnt offer much food value. In such conditions, these amazing plants have developed insect traps to get their nutritional (营养) needs over thousands of years. North America has more such plants than any other continent.Generally speaking, the traps may have attractive appearance to fool the eye, like pitcher plants, which get their name because they look like beautiful pitchers( a container like a bottle) full of honey.The Asian pitcher plant, for example, has bright colors and an attractive halfclosed cover. Curious insects are attracted to come close and take a drink, then fall down the slippery wall to their deaths.Some of these pitchers are large enough to hold two gallons(7.5 liters). Meateating plants only eat people in science movies, but sometimes a bird or other small animals will discover that a pitcher plant isnt a good place to get a drink.语篇解读本文是说明文。大自然千奇百怪，人们对食肉的动物并不陌生，但你见过食肉的植物吗？本文将为你介绍一二。1From Paragraph 1, we can know that meateating plants can _.A. catch 50 small insects in a secondB. catch an insect in the shortest timeC. be found floating on a quiet lakeD. notice an insect in 1/50 of a second答案与解析B细节理解题。第一段最后一句以bladderworts为例，它能在1/50秒内将昆虫捉住，说明这种植物捕捉昆虫的速度很快，B项符合文意。2What does it mean if the trap door of a meateating plant is closed?A. The plant is fooling insects into taking a drink.B. The plant is producing honey.C. The plant is attracting insects to come close.D. The plant is enjoying a dinner.答案与解析D推理判断题。第二段中讲到昆虫落网后，酶开始消化食物，吃完后叶子张开准备再次捕捉昆虫，因此可推知，叶子关闭说明植物正在享受大餐。3Meateating plants can grow in wet and poor soil because they _.A. can get nutrition from animalsB. dont need much food valueC. can make the most of such conditionsD. have developed digestive enzymes答案与解析A细节理解题。根据第三段可知，湿地的土壤不能提供给植物足够的营养。因此，食肉植物从落网的昆虫身上汲取营养，以维持生命。4We learn from the text that meateating plants _.A. are big and tallB. like to grow in dry landC. look bright and beautifulD. are usually covered with hair答案与解析C细节理解题。根据文中倒数第二、三段可知，食虫植物一般有迷人的外形，鲜亮的颜色，因而很容易吸引昆虫。BSetting up wildlife reserves is not just a matter of building a fence around an area and letting it grow “wild” First the area that is suitable for the creation of a reserve has to be identified and delimited (确定界限). This requires surveys to collect data on key species. A legal framework may need to be set up to control human activities in the area and in its immediate surroundings. (e.g. hunting, fishing, agriculture, industry and tourism) Policing the area may also be necessary. If part of the area has been worse due to bad land use it may need restoring. (e.g. 90% of tourists do not wander more than 100m from their cars, so the placing of car parks can greatly influence the impact of visitors.) Constant management will be needed to maintain the habitat of the species being conserved.What are the advantages and disadvantages of in situ conservation?In situ means conserving species where they are naturally found. This is preferable for several reasons： The species will have all the resources that it is adapted to (species in captivity have to adapt to special diets and artificial environments) In situ species have more space. Bigger breeding populations can be kept in situ. It is cheaper to keep an organism in situ.However there are problems. In situ it is difficult to control illegal exploitation (非法开发) In situ the environment may need restoring and species belonging to other different area or country are difficult to control.语篇解读本文是说明文。文章介绍了动物自然保护区的建立条件、其优势和劣势、一些注意事项和笼中动物饲养的区别。5Which one has nothing to do with building a wild life reserves?A. Doing surveys to collect data on key species.B. Setting up a legal framework to resist the humans activities.C. Maintaining the habitat of the species being conserved.D. Parking the cars everywhere in order to have an easy life.答案与解析D细节理解题。根据文章第一部分介绍建立自然保护区的条件，对比可知D项是和人类生活相关，但和建立自然保护区没关系。6What will be found in situ conservation?A. The species will have all the resources made by machine.B. The species will have a usual life just like their wild life.C. The species will be trapped in different cages.D. The species will be fed with manmade food.答案与解析B细节理解题。文章第二部分介绍动物可以吃到已经习惯的自然界的食物，有足够的空间，自由繁殖等，所以生活和野生基本一样。7Whats the main idea of this passage?A. The reason why we should set up reserves.B. The method of setting up reserves.C. The conditions of setting up reserves.D. Something about reserves and in situ conservation.答案与解析D主旨大意题。全文介绍了自然保护区的条件和in situ各方面的情况。CA Day of HopeA Day of Hope is a studentrun nonprofit (非营利性的) organization that sends baskets of food for Thanksgiving to poor families in Northern California.

I _19_ to work immediately, dropping hints (暗示) to my father about it.My first job was to tell him about how the steering (操纵杆) on my old car didnt _20_， but he just blamed the problems on my bad _21_.My next plan would have to be more _22_. “Look at this, Dad, the truck with controller and battery pack all for only $250! You cant _23_ to miss out on this bargain！”His _24_ was that he certainly could afford to miss this _25_ and for $250 you could buy _26_ educational like a telescope. “A telescope? To look at the moon? Ill look at it when Im 97 years old and living in a _27_ home! This is my youth! I am supposed to run about.”I went to my room, _28_ at how mean my father was. It was obvious that he didnt _29_ that I would die if I did not get the Pumpkin radiocontrolled truck.When I _30_ on Christmas morning I wasnt excited. I had been _31_. I opened all my presents until there was just one big package _32_. “The telescope，” I thought. I _33_ the packaging and I looked at the top of the box it was a Pumpkin truck.

I could _35_ get an A in English class.16A. pain B. attempt C. joy D. shyness17A. housing B. fishing C. car D. fashion18A. mind B. idea C. opinion D. head19A. get B. set C. searched D. went20A. operate B. run C. start D. work21A. riding B. driving C. thinking D. keeping22A. strong B. practical C. ideal D. obvious23A. afford B. pay C. allow D. stand24A. talk B. expression C. face D. response25A. truck B. telescope C. chance D. bargain26A. one B. something C. everything D. nothing27A. heating B. loving C. nursing D. finding28A. pleased B. good C. expert D. angry29A. say B. believe C. care D. learn30A. went off B. woke up C. rang up D. found out31A. worried B. instructed C. warned D. defeated32A. opened B. wrapped C. left D. faded33A. recovered B. refused C. reopened D. removed34A. won B. done C. beaten D. failed35A. ever B. already C. still D. even答案与解析语篇解读本文是记叙文。圣诞节快到了，作者想让爸爸送他一辆他看中很久的遥控车，可是爸爸无论如何都不同意。16A通览全文可知，作者为了得到这辆遥控车既经受了痛苦又付出了努力。17C联系上下文可知作者一直关注着遥控车的信息。18A根据上下文可知作者终于下定决心要那辆遥控车，make up ones mind为固定短语，意为“下决心”。19B由上文可知作者下定决心后就立即着手开始行动了。set to work“开始行动起来”。20D作者的第一步行动便是告诉爸爸旧车的操纵杆失灵了。work在这里意为“工作；有效”。21B联系上文可知，作者找的理由是旧车的操纵杆坏了，因此这儿与之相应的动词应当是“操作(drive)”。22D由于作者的第一步行动只是找了个借口，结果失败了，因此可以推知作者的第二步行动更“直白；明确(obvious)”了。23A由下一段第一句“. that he certainly could afford to miss .”可知本处应选A项。24D根据上下文可知，本句意为：“他的回应(response)是他的确不想买遥控车”。25D根据上一段最后一句“You cant _ to miss out on this bargain！”可知此处应选D项。26B联系下文可知，爸爸认为250美元可以买一些有教育意义的东西，one指代的是前文提到过的东西，something代替某种东西，故选B项。27C根据文化背景常识可知，作者觉得97岁应该在“养老院(nursing home)”里待着。28D根据前文讲到的作者多次提到买车均被爸爸拒绝，以及后文“how mean my father was”可推知作者此时的心情应该是“愤怒的(angry)”。29C前文讲到作者很愤怒，因此觉得爸爸根本不“在乎(care)”他的心情。30B根据后文“on Christmas morning”可知此处填woke up符合语境。go off意为“睡着；入睡”，ring up意为“给打电话”，find out意为“查明；弄清”，均不符合语境。31D根据前面作者认为爸爸根本不会给他买遥控车，以及前文“I wasnt excited”可知此时作者的心情应是“挫败(defeated)”的。32C根据前文“I opened all my presents”可推测，此时只剩最后一个包裹。33D联系上下文可知作者拆开了包裹，由下文可知package是包在box外面的，因此应该用remove, reopen意为“重开业；恢复”。34A联系上文的“I had been defeated”可知，作者在得到遥控车之后的心情应是觉得自己成功了，故选A项。35D联系上文可知作者在得到遥控车之后十分兴奋，觉得自己能做任何事情，“甚至(even)”可以在英语课上得A。第二节语法填空(共10小题；每小题1.5分，满分15分)阅读下面短文，在空格处填入适当的内容(每空不多于三个单词)或使用括号中单词的正确形式填空，并将答案填写在相应位置上。Woman: Welcome to our program. Today we 36._ (invite) Fred Watson, a driving instructor with over 20 years experience to talk to us about learning to drive. Well, Fred, 37._ you think its getting more expensive to learn to drive these days?Man: Well, 38._ depends. If you come to 39._ private instructor like me, its 40._ (probable) going to be a bit less expensive than going to a big school. The thing is, people have usually heard of the big schools and trust them, while I get customers through personal connections.Woman: Does that mean you have to try 41._ (hard) to get customers?Man: Not now. When I started I had to, but at the moment Im fully booked as my prices are quite competitive.Woman: Learning to drive is usually a nervous experience for 42._ (begin). What do you think?Man: Well, it can be! But I try to get them 43._ (sit) quietly in the drivers seat for a few moments with their eyes 44._ (close). Youd be surprised how it changes some people. They feel much more ready to drive if they have had a few quiet moments.Woman: Yes, I suppose some people are more nervous 45._ others.答案与解析36have invited所给词在句中作谓语且表已发生的动作，应用现在完成时。37do该空填助动词do引导一般疑问句式。38that/itThat/It depends.“看情况而定”。39a该空填不定冠词a，表“一个”。40probably所给词在句中作状语修饰动词going，应填副词形式probably。41harder这里指“要更努力寻找顾客”，应用比较级，填harder。42beginners所给词在句中作介词for的宾语，且根据句意“对于初学者而言学习驾驶通常是个紧张的经历”可知该空填beginners“初学者”。43to sit根据get sb. to do sth.“让某人做某事”结构可知该空填to sit。44closed所给词在句中作补语， close与其逻辑主语their eyes为被动关系，用其过去分词形式作补语。45than根据空格前的比较级more nervous可知该空填than。第三部分写作(共两节，满分35分)第一节短文改错(每小题1分，满分10分)英语课上，老师要求同桌同学相互修改作文。假设以下短文为你同桌所写，请你对其进行修改。文中共有10处错误，每句中最多有两处。错误涉及一个单词的增加、删除或修改。增加：在缺词处加一个漏词符号()，并在此符号下面写出该加的词。删除：把多余的词用斜线()划掉。修改：在错的词下划一横线，并在该词下面写出修改后的词。注意：1.每处错误及其修改均仅限一词。2只允许修改10处，多者(从第11处起)不计分。3必须按答题要求做题，否则不给分。Today my class went to large park to help collect rubbish. The park was dirty than we had expected. There were a great many of plastic shopping bags and plastic bottles. We spent about one hour clear away these things. Seeing so much rubbish, I began to understand why we are called up to protect the environment. Nowadays, it is being damaged by various type of pollution, but people hadnt realized the serious consequences. Many people just throw rubbish around casua
