Trees are useful to man in three very important ways：they provide him wood and other products;they give him shade;and they help to prevent drought(干旱)and floods.
Unfortunately，in many parts of the world，man has not realized that the third of these services is the most important.In his eagerness to draw quick profit from the trees，he has cut them down in large numbers Two thousand years ago，a rich and powerful country cut down its trees to build warships，with which to gain itself an empire It gained the empire but，without its trees，its soil became bare and poor.When the empire fell to pieces，the country found itself faced by floods and starvation.
Even where a government realizes the importance of a plentiful supply of trees，it is difficult sometimes to make the people realize this.They cut down the trees but are too careless to plant and look after new trees So，unless the government has a good system of control，or can educate the people，the forests slowly disappear
This does not only mean that there will be fewer trees.The results are even more serious：for where
there are trees，their roots break the soil up，allowing the rain to sink in， and also bind the soil.This prevents the soil from being washed away.But where there are no trees，the rainfalls on hard ground and flows away on the surface，and this causes floods and the rain carries away the rich topsoil in which crops grow When a11 the topsoil is gone.nothing remains but worthless desert.
41.Trees are useful to man mainly in three ways，the most important of which is that they can ____
A. keep him from the hot sunshine
B.enable him to build warships
C.make him draw quick profit from them
D .protect him from droughts and floods
42.It’s a great pity that ____
A.man is only interested in building empires
B.man is eager to profit from trees
C.man hasnt realized the importance of trees to him
D. man hasnt found out that he has lost all trees
43.Sooner or later the forests will disappear ______.
A. unless a country has a plenty supply of trees
B.unless people stop cutting down their trees
C.unless aIl people are taught the importance of planting trees
D.unless the government punishes those who cut trees instead of planting them
44.The word“bind”in Paragraph 5 means“____”
A.to wash away
B.to make wet
C.to make stay together
D.to improve
45. When there is a heavy rain.trees can help to prevent floods.as they can.
A.keep rain from falling down to soft ground
B，cause the soil to allow rainwater to sink in
C.prevent the soil from being washed away
D .make the topsoil stick together

Passage 3
树木对于人来说有3个重要益处：树木给人类提供木材和其他产物;树木可以让人们乘凉;树木可有效地防止旱涝灾害。
可惜的是，在世界上许多地方，人类没有认识到以上三个作用中，第三个是最重要的。人们急切于从树木上快速的谋取利益，于是大量的砍伐森林。
两千年之前，有一个富裕和强大的国家。为了建立帝国，砍倒了树木来造战舰。帝国建立了，但是，没有树木的土地变得荒芜和贫瘠。当帝国四分五裂的时候，整个国家发觉自己面临的是水灾和饥荒。 就算在政府认识到足够的树木储备的重要性时，有时却很难让人民也意识到这点。人们砍倒了树木，却疏于种植和照料树苗。因此，除非政府建立一套体制来控制或者教育人们，否则森林就会渐渐消失。
森林的消失不仅仅意味着树木的减少，还有更严重的后果。在有树的地方，树根不仅把土壤粉碎成小块，便于雨水的渗入，还可以牢牢的抓住泥土，防止泥土被冲刷走。但是在没有书的地方，雨水直接落在坚硬的地面，在土地表面流走。这不仅会导致洪水，雨水还会带走庄稼赖于生长的肥沃的表层土。当所有的表层土被冲走之后，除了毫无价值的沙漠之外，什么也没有了。
The global population is living longer，and getting older，阅读理解答案
The global population is living longer，and getting older，which presents new challenges. “The question becomes：who will take care of everyone While people will always be the best caregivers for people，there just aren’t enough people. That’s where robot17教育网：ic technology can really make a difference,” says Professor Maja Mataric at the University of Southern California.
Her group is developing robots to work with stroke (中风) patients and elderly people. The research team has found that people react well to a robot gym instructor，and seem to get less frustrated with it than with instructions given on a computer screen. The robot can act as a perfect trainer，with infinite(极大的) patience.
“People say things like ‘I prefer this robot to my husband!Can I take it home’” according to Professor Mataric. “In fact there’s a really important point here. As we create these care giving technologies，we’re helping not only the people that need the care，but also the people caring for them. We can give them a break，and help them avoid burnout.”
People are going to have to like，and importantly trust robots before they welcome them into their homes，and several groups around the world are working on making it easier to communicate with them.
Much of human communication takes place through body language. Gestures， eye contact , and concepts of personal space are all things that robots are being taught. In learning about how people interact(互动) with machines，researchers are also discovering new roles for robots in our lives. Robots can communicate with humans in ways that other technologies can not.
“If someone finds the robot to be more persuasive and more reliable，that’s going to affect how they interact with it,” says Dr Cynthia Breazeal, director of the Personal Robots Group at the Massachusetts Institute of Technology. “We can now start to think about fields where it’s the social interaction，which is the main means by which a robot helps someone.” Dr Breazeal says that means robots could be used in education，learning，and health care，where social support is important.
9.Professor Maja Mataric mainly focused on robots’ function of ________.
A.teaching B.exploring
C.making things D.giving care
10.Why can robots be wonderful trainers in the gym
A.Because they are more clever.
B.Because they give correct instructions.
C.Because they cost less money.
D.Because they are more patient.
11.The underlined word “burnout” in Paragraph 3 probably means “________”.
A.feeling tired B.feeling angry
C.getting hurt D.becoming disappointed
12.The scientists are presently working hard to help robots .
A.to use less electricity B.to communicate better
C.to react more quickly D.to have more functions

全球人口的寿命越来越长，年龄越来越大，这带来了新的挑战。“问题变成了：谁来照顾每一个人，而人们永远是最好的照顾者，只是人太少了。这就是机器人的问题。”教育网：南加州大学的Maja Mataric教授说，IC技术真的能起到作用。
她的团队正在开发用于治疗中风的机器人(中风) 病人和老年人。研究团队发现，人们对机器人健身教练的反应很好，而且似乎对机器人健身教练的失望程度比对电脑屏幕上给出的指令要低。该机器人可以作为一个完美的教练，具有无限的灵活性(极大的) 耐心
马塔里克教授说：“人们会说‘比起我的丈夫，我更喜欢这个机器人！我能把它带回家吗’。”。“事实上，这里有一个非常重要的观点。当我们创造这些护理技术时，我们不仅帮助了需要护理的人，也帮助了护理他们的人。我们可以让他们休息一下，帮助他们避免精疲力竭。”
人们在欢迎机器人进入自己的家之前，必须喜欢机器人，更重要的是要信任机器人。世界各地的几个组织正在努力让机器人更容易与它们沟通。
人类的大部分交流都是通过肢体语言进行的。手势、眼神交流和个人空间的概念都是机器人学习的内容。了解人们如何互动(互动) 有了机器，研究人员也发现了机器人在我们生活中的新角色。机器人可以用其他技术无法实现的方式与人类通信。
麻省理工学院个人机器人小组主任辛西娅·布雷泽尔博士说：“如果有人发现机器人更具说服力、更可靠，这将影响他们与机器人的互动方式。”。“我们现在可以开始思考社会互动的领域，这是机器人帮助他人的主要方式。”布雷泽尔博士说，这意味着机器人可以用于教育、学习和医疗保健，而在这些领域，社会支持非常重要。
英语阅读答案
Here’s something to think about the next time you ask your teacher for help：trying hard to do schoolwork on your own can help you learn.According to a recent study，the more you try while you are learning new information，the better you can remember it later.
This might surprise you.When teachers are presenting new information，they often give students lots of help.But a new study shows this may not be the best way to support learning.“Don’t be too quick to get help when learning something new，”education expert Ma Kapur said.“Try to work on it yourself even if it means trying different ways.’’
Kapur came up with the idea that trying hard can lead to better learning.Then he tested it out on students in Singapore.He separated students into two groups.In the first group，students were asked to solve math problems with the teacher’s help.In the second group，students were asked to solve the same problems by helping one another，instead of getting help from the teacher.
With the teacher’s help，students in the first group were able to find the correct answers.Students in the second group did not solve the problems correctly.But they did come up with a lot of good ideas.
The students were then tested on what they had 1earned.The group without any help from a teacher scored much higher than the group who had help.Kapur said working to find the answers helped students understand the process(过程)，not just the solution.
Kapur’s advice for kids is to put a 1ot of effort(努力)into learning something new rather than going to your teacher for help.“Simply doing a little work or nothing at all won’t work.”says Kapur.“Try to solve a problem in as many ways as possible.’’
13.What is the best title for the text
A.Work Your Mind
B.Practice Makes Perfect
C.The Best Way to Learn
D.Teachers’ Role in Schoolwork
14.Manu Kapur holds that _______ .
A.it’s necessary for students to ask for teachers’ help
B.students should try to solve problems by themselves
C.students with teachers’ help have more good ideas
D.students in the first group are cleverer than those in the second group

下次你向老师求助时，有件事需要考虑：努力自学可以帮助你学习。根据最近的一项研究，你在学习新信息时尝试得越多，你以后就能更好地记住它。
这可能会让你大吃一惊。当老师在介绍新信息时，他们经常给学生很多帮助。但一项新的研究表明，这可能不是支持学习的最佳方式。教育专家马卡普尔说：“学习新东西时，不要太快寻求帮助。”。“试着自己动手，即使这意味着尝试不同的方式。”
卡普尔提出了努力学习可以带来更好的学习的想法。然后他在新加坡的学生身上进行了测试。他把学生分成两组。在第一组中，学生们被要求在老师的帮助下解决数学问题。在第二组中，学生们被要求通过互相帮助来解决同样的问题，而不是从老师那里得到帮助。
在老师的帮助下，第一组的学生能够找到正确的答案。第二组的学生没有正确地解决问题。但他们确实想出了很多好主意。
然后对学生们所学知识进行测试。没有老师帮助的组比有老师帮助的组得分高得多。卡普尔说，努力寻找答案有助于学生理解这个过程(过程)，不仅仅是解决方案。
卡普尔给孩子们的建议是付出更多的努力(努力)学习新东西，而不是向老师寻求帮助。“简单地做一点工作或什么都不做是行不通的。”卡普尔说。“尽可能多地解决问题。”

I never thought 34 that marijuana (大麻) had a bad effect on those things. Maybe my coming to class high (神智恍惚) was the reason why I was failing or coming home late. As I continued to smoke marijuana, I began to notice that I would always have the strong desire to smoke and that I would get 35 cigarettes if I smoked those, but I don’t. 36 I have learned more about marijuana, I have 37 the amount of marijuana that I use. I don’t want marijuana to be the most important in my life. I’m not smoking every day, and not spending as much money. Since I have 38 on my habit, I am 39 more money.

A. tell B. explain C. regret D. share Part three :阅读理解 A 篇 There are hundreds of expressions of words using “hand” in the English language. Let us examine some of the expressions that use “hand”. We will get a hand in this way. “To get a hand in” is to begin a job, to begin to know something about it. When we learn completely, we will be able to do it hands down. If we do the job well, we may end up with the upper hand. On the other hand, if the situation gets out of hand, it is out of control. We must consider another way of expressing phrase---- to hand it to someone. For example, I must hand it to you for understanding what we have discussed this far. You can also lend a hand to someone but without really giving up your hand. You lend a hand when you help someone. If someone is kind enough to lend us a hand then we surely do not want to bite the hand that feeds us. We do not want to repay his kindness by treating him badly. Now, we have a free hand to continue examining other “hand” expressions. It means you are free to act without getting permission from someone else. Maybe you can find a friend who wants to take a hand in our project. It would have to be someone who was interested in these expressions. Your friend may want to work hand in glove with us. That is good because that means he wants to work as closely with us as a glove covers the hand. Of course, there is a danger that he may look at our project and decide to take it in hand. That means he wants to tale it over. If that happens, we may throw up our hands because the situation seams hopeless. In fact, we may decide that it is time for us to end this project to wash our hands of “ hand” expressions. 46.We are ready to do a certain job, we may say; Let’s ______________. A. get out of hand B. get a hand in C. lend a hand D. take a hand in 47.Which of the following has an unpleasant meaning? A. Hands down B. bite the hand that feeds us C. take a hand in D. hand in glove 48.Something is so easy to do. So you can do it____________. A. hands down B. on the other hand C. the upper hand D. hand in glove 49.What is the writer’s purpose in writing the passage? A. To tell us the fact that there are many phrases with “hands”. B. To prove the importance of the word “ hand ”. C. To tell us some phrases with “ hand ”. D. To make us laugh. B篇 If there is one thing I’m quite sure about, it is that in a hundred years from now we still be reading newspapers. Not those newspapers are a necessity. Even now some people get most of the news from the television or have the radio switched on in the background or in the car. Many buy a paper only on Saturday or Sunday. But for most people a newspaper has become a habit passed down from generation to generation. The basic British character won’t change, and one of the characteristics of the British is that we don’t much like talking to each other when we get up. So what better way is there to keep yourself thinking in the morning than to wrap yourself in a newspaper? Over the past couple of centuries, human beings have developed a close relationship with the newspaper. It has become as natural as breathing or enjoying the sun. And it is not just the British who love newspapers. On suburban trains in Calcutta, for instance, just one person in the whole car will buy a newspaper and read aloud the best bits to his fellow passengers, much to everybody’s enjoyment. The nature of what is news may change. What essentially (本质上) makes news is what affects our lives and the big political stories, the coverage of the wars, earthquakes and other disasters, will continue much the same. I think there will be more coverage of scientific research, though. It’s already happening in areas that may directly affect our lives, like genetic engineering. In the future I think there will be more coverage of scientific explanations of why we feel as we do, whether it’s love or depression. We develop a better understanding of how the brain operates and what our feelings really are. It’s quite possible that in the next century newspaper will be transmitted electronically from the national equivalents of Fleet Street (伦敦的舰队街，以报馆集中而著称) and printed out in our own homes. In fact, I’m pretty sure that that is how it will happen in future. You’ll be probably selecting from a menu, making up your own bespoke newspaper by picking out the things you want to read and say. You might even have an intelligent screening device (装置) to do the job for you. I think people have got it wrong when they talk about the competition between the different media. They actually have a relationship, feeding off each other. It was once predicted that television would kill off newspapers, which hasn’t happened. What is read on the printed page is more enduring (持久的) than pictures on a flickering screen or sound lost in the sky. And as for the Internet, it’s never really satisfying to read something just on a screen. 50. The author of the passage is most probably from _______________. A. Russia B. India C. Britain D. America 51. According to the passage, the future of newspapers ____________. A. will be mainly connected with scientific research B. will report more important political activities C. will directly cover more on scientific research D. will build a bridge between different people 52. The underlined part “bespoke newspaper” of the passage probably refers to _____________. A. a newspaper which dares to report the truth B. a newspaper edited to one’s own interest C. a newspaper edited and published for the public D. a newspaper which only covers the life of family members 53. Which of the following is TRUE according to the passage? A. It was centuries ago that newspapers came into being . B. Televisions have taken the place of newspapers . C. The Internet will gradually take the place of newspapers. D. The nature of news may remain the same over generations. 人教版高三英语选修6 Unit 3测试试卷答案 1-5 ADDDA 6-10.CAADC11-15.DDCBB16-20BAACA 21-25 ACAAA 26~45 BACDA BDABC CABDC AACCD46-53 BBAC CCBA看了人教版高三英语选修6Unit 3测试试卷及答案的人还看： 1. 高中英语完形填空试题及答案 2. 高中英语阅读专项试题 3. 2016年高考英语全国Ⅰ卷试题及答案 4. 高中英语完形阅读练习题及答案
