Unit 3 一、词汇复习（一）单句语法填空1 _(ignore) the difference between the two research findings will be one of the worst mistakes you make. 答案：Ignoring设空处位于句首，考虑句中可能缺少主语或状语，再分析句子成分，句中已有谓语动词will be，句中缺少的是主语，再根据句意可知应用动名词形式。句意为：忽视这两种研究结果的差异将是你所犯的最严重错误之一。分析句子结构可知，句子的谓语部分是will be，one of the worst mistakes是表语，you make是省略关系代词的定语从句，修饰mistakes。很显然，_ the difference between the two research findings是主语部分，结合语境可知设空处用动名词作主语。答案为Ignoring。2(2015课标全国，70)Abercrombie & Kent，a travel pany in Hong Kong，says it regularly arranges quick getaways here for people _ (live) in Shanghai and Hong Kong. 答案：living分析句子结构快速找到谓语动词arranges，从而判断此处应填非谓语动词；再根据句意可知，逻辑主语people与live之间为主动关系，最后确定填现在分词形式。句意为：香港的一家旅游公司Abercrombie & Kent说，他们经常在这儿为上海人和香港人安排方便的度假。该句的谓语动词是arranges，所以此处应是非谓语动词；people和live之间是主动关系，故填living作后置定语。3(2015北京，21改编)_(catch) the early flight，we ordered a taxi in advance and got up very early. 答案：to catchto catch在此作目的状语。句意：为了赶上早航班，我们提前订了出租车并且起得很早。4(2015北京，23改编)The park was full of people，_(enjoy) themselves in the sunshine. 答案：enjoyingenjoying为现在分词作伴随状语，与people形成逻辑上的主谓关系。句意：公园里人山人海，他们在沐浴着阳光愉快地玩耍。5(2015天津，5改编)_(absorb) in painting，John didnt notice evening approaching. 答案：Absorbed动词absorb有“使专心”之意，常见短语be absorbed in，所以用过去分词作原因状语。（二）英汉互译1. cigarette n. _2. alcohol n. _3. alcoholic adj. _4. abuse n. & vt. _ 5. fitness n. _6. sexual adj. _7. stress n. vt. _8. stressful adj. _9. obesity n. _10. adolescent n. adj. _11. adolescence n. _12. ban vt. n. _13. due adj. _14. due to _15. tough adj. _16. addicted adj. _17. addicted to _18. nicotine n. _19. accustom vt. _20. accustomed adj. _21. accustomed to _22. withdrawal n. _23. bad-tempered adj. _24. automatic adj_. 25. automatically adv. _26. mental adj. _27. mentally adv. _28. quit vt. _29. effect n. _30. lung n. _31. pregnant adj. _32. abnormal adj. _33. breathless adj. _34. unfit adj. _35. strengthen vt. vi. _36. resolve n. _37. decide on _38. packet n. _39. feel like (doing) _40. relaxation n. _41. desperate adj. _42. chemist n. _43. gum n. _44. chewing gum _45. disappointed adj. _46. weaken vi. vt. _47. ashamed adj. _48. prehension n. _49. in spite of _50. take risks (a risk) _51. get into 陷入；染上_52. etc (et cetera) adv. _53. appendix(复数-dixes, -dices）n. _ 54. illegal adj. _ 55. pill n. _56. robbery n. _57. slippery adj. _ 58. at risk _59. immune adj_. 60. survival n. _61. sex n. _62. fluid n. _63. inject vt. _64. injection n. _65. needle n. _66. spill （spilt, spilt） vi. vt. _ 67. male adj. n. _ 68. female adj. n. _69. condom n. _70. homosexual n. adj. _71. prejudice n. _ 72. judgement n. _ abortion n. _73. cigar n. _74. embarrassed adj. _75、awkward adj. _二、阅读理解ARecent months have seen a revival of the humble(普通的)bike across China, with an increasing number of people choosing pedaling(骑车)instead of driving to school, to workplaces or to do sightseeing. The introduction of bike-sharing systems, services in which bicycles are made available for shared use to individuals who do not own them and pioneered by start-ups like Ofo and Mobike, has brought the trend to a new level.Washington D. C. has one of the biggest bike sharing systems in the US with 3, 700 bikes and 440 stations. The UK, France and Germany all have growing programs. However, China, so far, outdoes(超过)them all by operating three out of four of the worlds shard bikes.People can unlock the shard bikes by simply using their smartphone. The bikes are equipped with GPS and users of Chinas versions can leave bikes anywhere in public for the next user. Theyre popular among many Chinese people as they provide an effective solution to the “last mile” problem, which refers to the final leg of a persons journey.However, the Chinese programs have also led to problems such as illegal parking, vandalism(故意破坏)and theft. In fact, these problems are also shared by bike-sharing programs abroad. Launched in 2007, Vilb is a large-scale public bike sharing system in Paris. At its early stage of operation, it also suffered from problems of vandalism or theft. By Oct 2009, a large number of Vlibs initial bikes had to be replaced due to vandalism or theft, according to The New York Times.To deal with these problems, the pany came up with the idea of encouraging people to return the bikes to stations by rewarding free time for their next rides. Now, Chinese service operators are also trying to address these problems. For example, Mobike sets a 100-point credit score for each user, with points taken in the case of bad behavior. Once a score drops below 80, bike rental is increased to 100 yuan per 30 minutes, up from 0. 5-1 yuan.1.What can we learn about bike sharing systems?A. They offer free bike rides.B. They are running perfectly.C. China operates the biggest system.D. France was the first to launch the system.2.As a means of transportation, bike-sharing can be best described as _.A. promising but expensive.B. convenient and eco-friendly.C. eco-friendly but ineffective.D. troublesome and meaningless.3.What can be a suitable title for the text?A. Shared Bikes Pedal into Style.B. Problems with Bikes in China.C. Shared Bikes Attract Young People.D. Transportation Changes with the Times.【文章大意】本文为说明文。讲述的是共享单车成为一种新的趋势，并介绍了它的优缺点。2.B 【解析】推理判断题。根据第三段可知共享单车方便而且环保，故选B。3.A 【解析】主旨大意题。纵观全文可知本文讲的是共享单车成为一种新的趋势，与A项一致，故选A。BBees play a vital role in the world. Unfortunately, bees are dying by the second. The main purpose of bees is to make honey. Honey, shockingly, does not exist for human consumption; it is essential to the insects. Honeybees store honey in their hives(蜂箱) in order for the bees to have energy for their flight muscles and for heating the hives during the winter period. They collect pollen(花粉) which supplies protein for young bees to grow.According to National Honey Board, the increased production and quality of agricultural crops as a result of honeybee pollination are valued at more than $14.6 billion per year. These insects are responsible for over 70 of the fruits and vegetables we eat today, including apples, grapes, coffee, beans, and broccoli.So if they are so valuable to agriculture, why do they keep dying off? A key suspect seems to be pesticides(农药). Honeybees who are exposed to pesticides result in the damage to their neurological(神经系统的) functions, specifically memory or behavior. And thats why the majority of worker bees disappear and leave behind a queen, plenty of food and a few nurse bees to care for the remaining immature bees and the queen. There are several other causes of the decline of bees, including the destruction of natural habitats, like woodlands, forests, and other habitats for bees. Climate change is also a factor in the decline of the wild bee population. Actually, there are a variety of methods to help the bee population grow. One way is to start your own organic garden by planting beefriendly plants. Pesticides are used in both industrial practices and even in your home, so it is best to find organic seeds and weed killers.【解题导语】本文是一篇说明文。蜜蜂在生物世界里起着重要的作用，但是由于农药的滥用，蜜蜂正在大批死亡。本文给出了增加蜜蜂数量的方法和建议。1Why do honeybees store honey in their hives?ATo provide enough honey for humans to consume.BTo draw protein out of honey for young bees.CTo help attract other insects and make hives stronger.DTo strengthen bee muscles and heat hives in winter.D解析：细节理解题。根据第二段的第三句“Honeybees store honey in their hives(蜂箱) in order for the bees to have energy for their flight muscles and for heating the hives during the winter period.”可知，蜜蜂储藏蜂蜜是为了增强飞行肌肉的力量，在冬天为蜂箱加热，故D项正确。2Apples and beans are mentioned in the third paragraph to show that Abees supply human beings with basic foodBbees mainly live on these agricultural cropsCbees are of great importance to fruits and vegetablesDbees can bring in more money for farmers every yearC解析：细节理解题。根据第三段的“These insects are responsible for over 70 of the fruits and vegetables we eat today, including apples, grapes, coffee, beans, and broccoli.”可知，该段提及苹果和豆类旨在说明蜜蜂对水果和蔬菜的重要作用，故C项正确。3What is most likely to cause the worker bees to leave their hives behind?AThe lack of food.BThe abuse of pesticides.CThe fighting among bees.DThe destruction of the habitats.B解析：细节理解题。根据第四段的“Honeybees who are exposed to pesticides.And thats why the majority of worker bees disappear”可知，农药的滥用导致了工蜂离开蜂箱，故B项正确。4What would the author probably discuss in the paragraph that follows?AAnother way to save bees.BOther tips for choosing seeds.CMore methods to plant green organic fruits.DCauses of the decline in the wild bee population.A解析：推理判断题。根据第五段的第一、二句“Actually, there are a variety of methods to help the bee population grow. One way is to start your own organic garden by planting beefriendly plants.”可知，该段主要介绍了帮助蜜蜂增加数量的方法之一：种植对蜜蜂无害的植物。据此可以推断，下文将介绍其他的帮助增加蜜蜂数量的方法，故A项正确。三、七选五The Science of Risk-SeekingSometimes we decide that a little unnecessary danger is worth it because when we weigh the risk and the reward, the risk seems worth taking. 1 Some of us enjoy activities that would surprise and scare the rest of us. Why? Experts say it may have to do with how our brains work.The reason why any of us take any risks at all might have to do with early humans. Risk-takers were better at hunting, fighting, or exploring. 2 As the quality of risk-taking was passed from one generation to the next, humans ended up with a sense of adventure and a tolerance for risk.So why arent we all jumping out of airplanes then? Well, even 200,000 years ago, too much risk-taking could get one killed. A few daring persons survived, though, along with a few stay-in-the-cave types. As a result, humans developed a range of character types that still exists today. So maybe you love car racing, or maybe you hate it. 3 No matter where you are on the risk-seeking range, scientists say that your willingness to take risks increases during your teenage years. 4 To help you do that, your brain increases your hunger for new experiences. New experiences often mean taking some risks, so your brain raises your tolerance for risk as well. 5 For the risk-seekers, a part of the brain related to pleasure bees active, while for the rest of us, a part of the brain related to fear bees active.As experts continue to study the science of risk-seeking, well continue to hit the mountains, the waves or the shallow end of the pool.A. It all depends on your character.B. Those are the risks you should jump to take.C. Being better at those things meant a greater chance of survival.D. Thus, these well-equipped people survived because they were the fittest.E. This is when you start to move away from your family and into the bigger world.F. However, we are not all using the same reference standard to weigh risks and rewards.G. New brain research suggests our brains work differently when we face a nervous situation.【语篇解读】这是一篇说明文，作者讲的是有关冒险的科学的探索方面的内容。1.F 【解析】选项F中的weigh risks and rewards与上文的weigh the risk and the reward相呼应，故F项符合语境。2.C 【解析】选项C中的Being better at those things与上文的were better at hunting, fighting, or exploring相呼应，因此选C。3.A 【解析】前文说人们有各种不同的性格，因此你可能喜欢赛车，或者讨厌赛车，故A项这完全是由你的性格决定的符合语境。4.E 【解析】根据上文的your willingness.teenage years及下文的hunger for new experiences.可知E项符合语境。5.G 【解析】根据空后的For the risk-seekers.bees active可知，此处讲的是面对紧张的局面时我们的大脑会有不同的反应，故G项符合语境。
