do certain things．And so，people thought that each part of the brain does a different job．But modern research has discovered that this is not so，for it is not easy to show exactly what each part of the brain does．In the past fifty years there has been a great increase in the amount of research done on the brain．Scientists have found out that the way the brain work is not so simple as people in general may think．Chemists tell us that about 1 00 000 chemical changes take place in the brain every second．Some recent researches also suggest that we can remember everything that happens to us．We may not be able to think of the things we have heard and seen，but it is all kept there in the storehouse of the human mind．Earlier scientists thought that the power of one’s brain got weaker and weaker as one grew older．But it is now thought that that’s not true．As long as the brain is given plenty of exercise，it keeps its power．It has been proved that an old person who has always been active in the mind has a quicker mind than a young person who has only done physical work without using much of his brain．( )1．In the last century，scientists found that a person would lose the power to do certain things————．A．when he had drunk too much B．if certain parts of his brain were hurtC．after he did a quite different job D．if he had been greatly frightened( )2．Scientists today are still unable to show exactly——．A．how many chemical changes take place in the brain each secondB．whether each part of the brain does the same workC．what each part of the brain is doing ．D．which part of the brain is the most important( )3．It has been found that the brain usually works ．A．in a fairly complicated(复杂)way B．a little now and a little thenC．without any rest all day long D．in a very simple way( )4．Which of the following is not true“——．A．Scientists are working hard to solve(解决)the mysteries of the brainB．As many as six million changes take place in the brain every minuteC．A young man doing physical labor is sure to have a much slower mindD．Even an old man may have a quick mind only if his brain is given much exercise( )5．The more work our brains have，——．A．the less result we will gain B．the more

精编高一英语(人教版)作业手册：必修2Unit4 Wildlife protection Word版含答案
课时作业(九)[必修2Unit 4 Wildlife protection](限时：30分钟)Ⅰ.阅读理解AThe secret of carrier pigeons' unbelievable ability to find their way home has been discovered by scientists; the feathered navigators follow the roads just like we do.Scientists now believe the phrase “as the crow flies” no longer means the shortest most direct route between two points.They say it is likely that crows and other birds also choose AA-suggested routes, even though it makes their journeys longer.Scientists at Oxford University spent 10 years studying homing pigeons using global positioning satellite(GPS) and got a surprising result.The birds often don't use the sun to decide their directions.Instead they fly along motorways, turn at crossing and even go around roundabouts(绕道), adding miles to their journeys.“It really has knocked our research team sideways to find that after a decadelong international study, pigeons appear to ignore their inbuilt directional instincts(本能) and follow the road system，”said Prof Tim Guilford, reader in animal behaviour at Oxford University's Department of Zoology.Guilford said pigeons use their own navigational system(导航系统) when doing long distance trips or when a bird does a journey for the first time.“But once homing pigeons have flown a journey more than once, they can fly home on a habitual route, much as we do when we are driving or walking home from work，” said Guilford.“In short, it looks like it is mentally easier for a bird to fly down a road.They are just making their journey as simple as possible.”1．What would be the best title of the passage?A．How pigeons find their ways homeB．Why pigeons can fly the long distanceC．Birds follow roads as we doD．Why crows fly the shortest distance2．Scientists used to think that homing pigeons often find their directions________．A．by global positioning satelliteB．by the sunC．by the road systemD．by following other birds3．Why do homing pigeons tend to follow the road system during their journey?A．Because they don't have their inbuilt directional instincts now.B．Because their own navigational system doesn't work.C．Because it is too hard to use their own navigational system.D．Because it is easier to make journey simple by following the road system.BAn idea that started in Seattle's public library has spread throughout America and beyond.The concept is simple：help to build a sense of community in a city by getting everyone to read the same book at the same time.In addition to encouraging reading as a pursuit(追求) to be enjoyed by all，the program allows strangers to communicate by discussing the book on the bus，as well as promoting reading as an experience to be shared in families and schools.The idea came from Seattle librarian Nancy Pearl who launched the “If All of Seattle Read the Same Book”project in 1998.Her original program used author visits，study guides and book discussion groups to bring people together with a book，but the idea has since expanded to many other American cities，and even to Hong Kong.In Chicago，the mayor appeared on television to announce the choice of To Kill a Mockingbird as the first book in the “One Book，One Chicago” program.As a result，reading clubs and neighbourhood groups sprang up around the city.Across the US，stories emerged of parents and children reading to each other at night and strangers chatting away on the bus about plot and character.The only problem came up in New York，where local readers could not decide on one book to represent the huge and diverse population.This may show that the idea works best in medium-sized cities or large towns，where a greater sense of unity can be achieved.Or it may show that New Yorkers missed the point，putting all their energy and passion into the choice of the book rather than discussion about a book itself.Ultimately，as Nancy points out，the level of success is not measured by how many people read a book, but by how many people are enriched by the process，or have enjoyed speaking to someone with whom they would not otherwise have shared_a_word．4．What is the purpose of the project launched by Nancy?A．To invite authors to guide readers.B．To encourage people to read and share.C．To involve people in community service.D．To promote the friendship between cities.5．Why was it difficult for New Yorkers to carry out the project?A．They were too busy to read a book.B．They came from many different backgrounds.C．They had little interest in reading.D．They lacked support from the local government.6．According to the passage，where would the project be more easily carried out?A．In large communities with little sense of unity.B．In large cities where libraries are far from home.C．In large towns where agreement can be quickly reached.D．In mediumsized cities with a diverse population.7．The underlined words “shared a word”in Paragraph 5 probably mean “________”．A．discussed the meaning of a wordB．exchanged ideas with each otherC．gained life experienceD．used the same language8．According to Nancy，the degree of success of the project is judged by ________．A．the number of people who benefit from readingB．the careful selection of a proper bookC．the growing popularity of the writersD．the number of books that each person readsⅡ.语法填空A: Hello.

Unit 4 Wildlife Protection Language points课时作业[高考题型练习提能力]Ⅰ.阅读理解AThe Bike Experience is a charity that teaches and advises motorcyclists who have been disabled how they can ride again，through the provision ofan adapted and modified motorcycle，which will allow them toride in a safe environment using a logical stepbystep process.The Bike Experience was formed in April 2011，as therewas no project in existence that taught disabled motorcyclists how to ride.Over a period of five years，the initial idea has become a registered charity.Over 75 disabled motorcyclists have learned to ride again and the concept has started to influence the motorsport world.In March，2003，Talan SkeelsPiggins，the founder of the charity，was knocked off his motorcycle and thrown under the path of the oncoming traffic.The accident left him paralyzed (瘫痪的) from the chest down and he thought he would never ride a motorcycle again.Eight years later，Talan was back riding a motorbike on UK track days and felt the importance of teaching others how to do the same.Talan says，“When I am riding，I do not feel disabled.I feel free from my wheelchair，and I enjoy the sense of excitement and independence just as I used to.Getting to this point has been a struggle，but it has been worth it.I wanted to help other disabled motorcyclists have the fantastic feeling of being back on a bike，without the falls and setbacks I suffered，so The Bike Experience Charity was established.”In addition to getting riders back on two wheels，The Bike Experience charity aims to：●Help the individuals who take part develop a positive attitude.●Advise participants how to buy their own bike，adapt it and ride independently and safely.●Improve the participant's physical health，balance，coordination，strength and stamina(耐力)．●Evolve attitudes in the motorcycling world so that disabled motorcycle riding motorcycles can be considered possible，feasible and acceptable.【语篇解读】本文主要介绍了慈善机构The Bike Experience Charity为残疾人提供特殊的摩托车，以便他们能再次安全地驾驶。

北部白犀牛小嘴狐猴Extinction is for ever!As almost everyone knows，to become extinct is to be gone for ever.Even before man's arrival on Earth，species became extinct quite naturally.Natural extinction happens when a species decreases in numbers gradually but steadily at the end of its evolutionary period on Earth.The length of this period depends on how well a species can get used to changes around it.This process of extinction can take a very long time—sometimes several million years—and the extinction of one species is immediately followed by the appearance of another in a continuous cycle.The case of the dinosaurs is the most well－known example of natural extinction.They appeared on Earth about 200 million years ago and dominated （统治）both land and sea for almost 100 million years.It is not certain why the dinosaurs became extinct，but their disappearance was a natural one and new species of animals evol ved to replace them.The rate of extinction has speeded up unnaturally over the last 400 years，rising sharply since 1990.This increase in the rate of extinction is directly related to the increase in the human population over the same period of time.The great number of humans has caused great damage to the planet，as wild habitats have been taken over，forcing animals and plants into smaller and smaller areas，until some of them have become extinct.We have also polluted some habitatswith chemicals and waste，making them unfit for wildlife.These causes of extinction are known as indirect destruction.Animals may also become extinct through direct destruction.This includes the hunting and catching of animals.Man has always hunted and killed wildlife but whenearly humans lived more in harmony with nature，they killed animals for essential food and clothing.When firearms were invented，great destruction of species was possible.Animals have been，and still are，killed for meat，clothing，medicines，feathers，eggs—and sometimes just for amusement.Some species are still caught in the wild for the live pet trade，even though their numbers are decreasing.The extinction of at least 500 species of animals has been caused by man.Today there are about 5，000 endangered animals and at least one species dies out every year.There are probably many more which become extinct without anyone knowing.【词海拾贝】1．extinction n．灭绝；绝种2．steadily adv.平稳地3．continuous adj.连续不停的；不间断的4．habitat v．栖息地5．destruction n．破坏【问题思考】阅读短文，判断正(T)误(F)。

课时作业(十四)Unit 4 Wildlife protectionSection ⅡWarming Up & Reading—Language PointsⅠ.单句语法填空1.He came to my class every week, but his attitude suggested that he was (be) not really interested in it.2.The protection (protect) of wildlife is not anything to be left to the government. Everyone should be concerned about it.3.As is known to all, the panda is a(n) endangered (danger) species on the earth.4.Many young people risk hearing loss (lose) as a result of loud music on portable (便携式的)devices.5.Much to his relief (relieve), his father has recovered from his illness.6.The picture quality is not good because the TV signal isn't powerful (power) enough.7.We are collecting money for the areas affected (affect) by the floods.8.Linda has found it hard to_employ (employ) enough workers with these skills.9.Carol's negative response (respond) suggested that she did not want to go camping with them.10.After the boat's motor failed, they were at the mercy of the weather.Ⅱ.阅读理解Animals are natural resources that people have wasted all through our history.Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.Why should people care? Because we need animals. And because once they are gone, there will never be any more.Animals are more than beautiful or interesting or a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems.For example, when farmers killed large numbers of hawks (鹰), the farmers' stores of corn and grain were destroyed by mice. Why? Because hawks eat mice. With no hawks to keep down their numbers, the mice multiplied quickly.Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger.Quite a few countries have passed laws. These laws forbid the killing of any animal or plant on the danger list. Slowly, the number of some animals in danger is growing.【文章大意】本文是一篇关于动物保护的说明文。
