5. Passage Twenty-TwoThough some people have suggested that women should return to housework in order to leave more jobs for men， the idea has been rejected by both women and men in public opinion polls (民意测验).Lately some union officials have suggested that too many women are employed in type of work more suitable for men and that women should step aside to make way for unemployed young men.They argue that women—especially women in their childbearing years actually delay economic development and result in lower productivity， poor quality and inefficiency.To solve the problem， they have suggested that the working women stay at home while their husbands or brothers were given double wages.They argue that under these circumstances， families would retain their same level of income， and women could run the house and raise children much better.The suggestion has been rejected by 9 out of 10 people polled.A hundred persons in a big city were questioned last summer.Out of 50 women， 46 said they were unwilling to leave their jobs， no matter what the situation was.The other 4 said they would like to return home if their jobs could be taken by their sons or daughters.Of 50 men polled， only 6 said they would like to see their wives give up their jobs， if it meant higher wages for themselves.Some other people have suggested another way called “phased employment theory”.The theory suggests that a woman worker take leave from her job when she is seven months pregnant (妊娠)and stay off the job until her baby reaches the age of 3.It suggests that women on leave receive 75 percent of their normal salary and be allowed to return to work after the 3-year period.This will benefit children， women， their families and the society.Some of those polled， both women and men， felt the idea is a good one.It definitely seems to be more acceptable than the suggestion that women return to home forever.According to the “phased employment” theory， during a woman’s leave from her job ().

34. Questions 31 to 35 are based on the following passage.To write his 2010 book， The 5-Factor World Diet， nutritionist Harley Pasternak traveled to the healthiest countries around the world to learn more about what made their meals extra nourishing.He noted that Japanese people ate a wonderful variety of seaweeds， and that Chinese people tried to include at least five different colors in every meal.Pasternak also came away with some valuable observations about how different the North American way of life was， compared with many other countries.For starters， Americans eat much bigger portions than people in other countries.“We don’t prioritize eating seasonally or locally， and we also add lots of salt， sugar and thickening agents to our foods，” explained Pasternak.Contrast that to the healthy Mediterranean， Nordic and Okinawan diets listed in Pasternak＇s book.They all seem to stick to the ethos (特质)of regional， seasonal produce.For example， a traditional Mediterranean diet includes fruits， vegetables， whole grains， nuts and olive oil as the main components of nutritional intake.Fish， chicken and red wine make moderate appearances， while red meat， salt and sugar are used much less often.The benefits of a traditional Mediterranean diet have been studied since the 1970s， and researchers have found that living that olive oil life can help people lose weight， lower their heart disease risk and reverse diabetes.Most other healthy eating cultures also make meals an event—say， multiple courses around the family table， or a glass or two of red wine at a long lunch—opposed to hastily wolfing down handfuls of cereal above the kitchen sink and calling it dinner.Each of the healthy eating cultures has its own unique feature.But Pasternak did take note of one unifying factor in all of the healthy societies he observed.“The only overlapping feature in most of these healthy countries is that they all walk way more than the average American，” said Pasternak.“So really， regardless of what you’re eating， if someone’s walking four miles more than you each day， they are going to be a lot thinner and live a lot longer than you.”What do people in most healthy eating cultures have in common?

A. 　They get the whole family to eat at a table.

B. 　They eat their meals regularly and punctually.

C. 　They consume plenty of cereal for breakfast.

D. 　They attach great importance to their meals.

2. Passage SeventeenNo one knows how man learned to make words.Perhaps he began by making sounds like those made by animals.Perhaps he grunted like a pig when he lifted something heavy.Perhaps he made sounds like those he heard all round him——water splashing， bees humming， a stone falling to the ground.Somehow， he learned to make words.As the centuries went by， he made more and more new words.This is what we mean by language.People living in different countries made different kinds of words.Today there are about fifteen hundred different languages in the world.Each contains many thousands of words.A very large English dictionary， for example， contains four or five hundred thousand words.But we do not need all these.Only a few thousand words are used in everyday life.The words you know are called your vocabulary.You should try to make your vocabulary bigger.You’re supposed to read as many books as you can.There are plenty of books written in easy English for you to read.You will enjoy them.When you meet a new word， you should find it in your dictionary.Your dictionary is your most useful book.The number of different languages spoken is about ().

38. Questions 36 to 40 are based on the following passage.Some people have said aging is more a slide into forgetfulness than a journey towards wisdom.However， a growing body of research suggests that late-in-life learning is possible.In reality， education does an aging brain good.Throughout life， people’s brains constantly renovate themselves.In the late 1960s， British brain scientist Geoffrey Raisman spied growth in damaged brain regions of rats through an electron microscope; their brains were forging new connections.This meant brains may change every time a person learns something new.Of course， that doesn’t mean the brain isn’t affected by the effects of time.Just as height usually declines over the years， so does brain volume: Humans lose about 4 percent every decade starting in their 40s.But that reduction doesn’t necessarily make people think slower; as long as we are alive and functioning， we can alter our brains with new information and experiences.In fact， scientists now suspect accumulating novel experiences， facts， and skills can keep people’s minds more flexible.New pathways can strengthen our ever-changing mental structure， even as the brain shrinks.Conventional fixes like word puzzles and brain-training apps can contribute to mental durability.Even something as simple as taking a different route to the grocery store or going somewhere new on vacation can keep the brain healthy.A desire for new life challenges can further boost brainpower.Research about aging adults who take on new enterprises shows improved function and memory as well as a reduced risk of mental disease.Openness—a characteristic defined by curiosity and a desire for knowledge—may also help folks pass brain tests.Some folks are born with this take-in-the world attitude， but those who aren’t as genetically gifted aren’t necessarily out of luck.While genes can encourage an interest in doing new things， a 2012 study in the journal Psychology and Aging found completing reasoning tasks like puzzles and number games can enhance that desire for novel experiences， which can， in turn， refresh the brain.That’s why brain scientist Richard Kennedy says “It’s not that old dogs can’t learn new tricks.It’s that maybe old dogs don’t realize why they should.”What is one thing that helps maintain the health of our brain even as it shrinks?

A. 　Doing daily routines by conventional means.

B. 　Avoiding worrying about our mental durability.

C. 　Imitating old dogs’ way of learning new tricks.

D. 　Approaching everyday tasks in novel ways.

5. Passage ElevenDoctors say anger can be an extremely damaging emotion， unless you learn how to deal with it.They warn that anger can lead to heart disease， stomach problems， headaches， emotional problems and breast cancer.Anger is a normal emotion that we all feel from time to time.Some people express anger openly in a calm and reasonable way.Others burst with anger， screaming and yelling.But still others keep their anger inside.They cannot or will not express it.This is called (repressing)anger.For years some doctors claim that both repressing and expressing anger can be dangerous.They say that in both situations the brain of an angry person releases the same hormones (荷尔蒙).They spend the heart rate， raise blood pressure or sugar level in the blood.As a result， the angry person feels excited and is ready to react.The violent reaction may lead to high blood pressure.However， some other doctors argue that repressing anger is more dangerous to a person’s health than expressing it.They believe that those who keep their anger inside may face a greater danger of heart disease.Most doctors agree that it is important to learn how to deal with anger.They say the first step is to admit that you are angry and recognize the real cause of the anger， then decide if the cause is serious enough to get angry about.If so， you should not express your anger immediately and try to wait until your anger has cooled down， so that you are able to express yourself calmly and reasonably.They also believe that a good way to deal with anger is to find humor in the situation that has made you angry.After all， it is much healthier to laugh than to get angry.We can conclude from the passage that the cost and the quality of a university are ().

3. Passage Twenty-NineHow can we get rid of garbage (垃圾)? Do we have enough energy sources to meet our future energy needs? These are two important questions that many people are asking today.Some people think that man might be able to solve both problems at the same time.They suggest using garbage as an energy source， and at the same time it can save the land to hold garbage.For a long time， people buried garbage or dumped (倾倒)it on empty land.Now， empty land is scarce.But more and more garbage is produced each year.However， garbage can be a good fuel to use.The things in garbage do not look like coal， petroleum， or natural gas; but they are chemically similar to these fossil fuels.As we use up our fossil-fuel supplies， we might be able to use garbage as an energy source.Burning garbage is not a new idea.Some cities in Europe and the United States have been burning garbage for years.The heat that is produced by burning garbage is used to boil water.The steam that is produced is used to make electricity or to heat nearby buildings.In Paris， France， some power plants burn almost 2 million metric tons of the city’s garbage each year.The amount of energy produced is about the same as would be produced by burning almost a half million barrels of oil.Our fossil fuel supplies are limited.Burning garbage might be one kind of energy source that we can use to help meet our energy needs.This method could also reduce the amount of garbage piling up on the earth.According to the passage， which of the following is NOT true?
