Unit 2 Working the land Period 4 Using Language課后閱讀作業(yè). 閱讀理解APeople used to think that wetlands were wasted land. Developers would drain them with ditches(水溝), fill them in with tons of soil, and build houses, schools, and parking areas on them. Then scientists began to realize the important role wetlands play in the environment. Wetlands act like giant sponges(海綿)during storms. They soak up extra storm water and afterward release it slowly back into the water cycle. This helps prevent flooding. Towns where people have drained wetlands have found that in a big storm, their streets and homes are often flooded because there are no wetlands to soak up the excess water. Wetlands also act as giant filters where pollutants are absorbed and dissolved over time. Though wetlands can become polluted from dumping, wastewater, and fertilizer runoff from farm fields, they are able to process some pollutants over time because of all the microorganisms and plants living there. Wetlands are especially important for providing homes and breeding grounds to millions of birds, fish, and amphibians worldwide. Many wetlands have become national wildlife refuges(避難所), where you can go to take pictures and look at birds and animals. The Everglades are a huge wetland that once covered more than four million acres of southern Florida. Sometimes called the“river of grass”, the Everglades are a shallow sheet of water that slowly flowed across a grassy plain. In the late 1800s people began draining parts of the Everglades for development. Roads were built and towns sprang up. The Everglades shrank to half its original size. Cities like Miami grew up where once there was a thriving wetland. Sewage and waste from the cities were pumped into the remaining wetlands. Over time scientists began to see the importance of the Everglades. Even with its smaller size, the Everglades filtered the pollutants coming from the cities, absorbing the worst of it like a sewage treatment plant. During storms the Everglades protected the cities from storm surge flooding. They also are just a great place to visit and see wildlife. 【語篇概述】本文講述了濕地的重要性。1.

Regrettably, mosquitoes can do more than cause an itchy(發(fā)癢的)wound. Some mosquitoes spread several serious diseases, including Dengue, yellow fever and malaria. Over one million people worldwide die from these diseases each year. New research now shows how mosquitoes choose who to bite. Mosquitoes need blood to survive. They are attracted to human skin and breath. They smell the carbon dioxide gas, which all mammals breathe out. This gas is the main way for mosquitoes to know that a warm-blooded creature is nearby. But mosquitoes also use their eyes and sense of touch. Michael Dickinson is a professor at the California Institute of Technology. His research shows how these small insects, with even smaller brains, use three senses to find a blood meal. Michael Dickinsons team used plumesa material that rises into the air of carbon dioxide gas into a wind tunnel. They then used cameras to record the mosquitoes. The insects followed the plume. Then, the scientists placed dark objects on the lighter colored floor and walls of the tunnel. Mr Dickinson said, at first, the mosquitoes showed no interest in the objects at all. “What was quite striking and quite surprising is that the mosquitoes fly back and forth for hours. These are hungry females and they completely ignore the objects on the floor and wall of the tunnel. But the moment they get a bit of CO2, they change their behavior quite obviously and now would become attracted to these little visual blobs(斑點). ”This suggested to the researchers that a mosquitos sense of smell is more important in the search for food. Once mosquitoes catch a smell of a human or animal, they also follow visual signals. 【語篇概述】本文解釋了蚊子叮人的依據(jù)。文章中通過實驗證明了蚊子主要依據(jù)二氧化碳來追蹤叮咬目標。5. What do mosquitoes mainly use to find their targets? A. Sense of smell. B. Sense of touch. C. Sense of sight. D. Smart brains. 【解析】選A。細節(jié)理解題。根據(jù)第三段最后一句可以得出蚊子依靠嗅覺叮人。6. The first response of the mosquitoes to the objects in the experiment is_. A. to fly to the dark onesB. to catch and stick to themC. to take no notice of themD. to attach themselves to them【解析】選C。細節(jié)理解題。根據(jù)第六段第二句Mr Dickinson said, at first, the mosquitoes showed no interest in the objects at all. 可以得出本題答案C。7. How can we avoid being attacked by mosquitoes according to the text? A. Dont let them see us. B. Use dark objects to stop them. C. Make them fly back and forth for hours. D. Attract them to objects full of carbon dioxide gas. 【解析】選D。推理判斷題。根據(jù)倒數(shù)第二段最后一句當蚊子感受到二氧化碳時候, 蚊子很明顯改變其行為, 被二氧化碳源頭所吸引, 因而可以推斷出蚊子對CO2很敏感, 可以用CO2誘騙蚊子。8. What can be the best title for the text? A. How Do Mosquitoes Survive? B. Why Do Mosquitoes Need Blood? C. How Do Mosquitoes Choose to Bite You? D. Why Do Mosquitoes Attack the Human Being? 【解析】選C。主旨大意題。根據(jù)第二段最后一句New research now shows how mosquitoes choose who to bite. 可以得出本文大意蚊子怎樣選擇叮人。. 完形填空Dear editor, Im a student in a common agricultural university. As you know, few people think1of an agricultural university, especially which is not2. It is ten times3difficult for a graduate from our university to4a satisfactory job than for those who5more respected subjects at a famous university. Most graduates from our university can6to be treated coldly. Last year a7from our university attended a talent fair(人才招聘會)8in Guangzhou.

Yours, Li Hua【語篇概述】招聘時, 用人單位是看重大學的名氣還是更注重專業(yè)技能呢? 閱讀本篇, 感受一個農業(yè)大學畢業(yè)生的困惑吧! 1. A. lowlyB. highlyC. littleD. greatly【解析】選B。固定搭配題。聯(lián)系全文我們可以知道, 人們對農業(yè)大學, 尤其是非名牌農業(yè)大學并不看重, 空前的few決定了其他答案不能入選。think highly of看重。2. A. well-knownB. beautifulC. importantD. skillful【解析】選A。邏輯推理題。從第三段中的“Sorry, if you had graduated from Peking University, we would take you on. ”我們得知, 招聘者看重的是大學的名氣, 而不是技能的重要性。從全文來看可排除其他選項。3. A. greaterB. lessC. fewerD. more【解析】選D。邏輯推理題。本空承接上句而來, “很少有人看得起農業(yè)大學, 尤其是非名牌農業(yè)大學”, 因此我們大學的畢業(yè)生找工作更加困難。A、C不能修飾形容詞。B項與語意相反。4. A. acceptB. findC. changeD. follow【解析】選B。固定搭配題。find a job意思是“找工作”。通讀全文, 我們可以知道, 作者談論的是大學生找工作難的問題, 而不是接受工作或改變工作, 因此A、C不合題意。5.

A. giveB. shareC. letD. hand【解析】選D。固定搭配題。聯(lián)系上下文我們可以得知, 這名畢業(yè)生要參加求職面試, 因此他首先要遞交(hand in)他的面試推薦表。give in意思是“屈服, 投降”; share in意思是“分擔”; let in意思是“讓進入”, 都不符合題意。10. A. timeB. turnC. chanceD. interview【解析】選B。邏輯推理題。由前文的He joined a queue. . . 我們知道, 他是站在求職者的隊伍中排隊等候, 因此作者說“當輪到他時”。11. A. addressB. telephoneC. nameD. number【解析】選C。前后照應題。從后文“What?
