Can exercise during childhood protect you against memory loss many decades later?Exercise early in life seems to have lifelong benefits for the brain,in rats at least.

“This is an animal study,but it shows that physical activity at a young age is very important—not just for physical development,but for the whole lifelong track of cognitive（认知的）development during ageing,”says Martin Wojtowicz of the University of Toronto,Canada.“In humans,it may delay the appearance of Alzheimer's symptoms（阿茨海默氏症）,possibly to the point of preventing them.”

Wojtowicz’s team divided 80 young male rats into two equal groups,and placed running wheels in the cages of one group for a period of six weeks.Around four months later—when the rats had reached middle age—the team taught all the rats to connect an electric shock with being in a specific.When placed in the box,they froze with fear.

Two weeks later,the team tested the rats in three situations: exactly the same box in the same room,the same box with the room arranged differently,and a completely different box in a different room.

The rats without access to a running wheel when they were young now froze the same percentage of times in each of these situations,suggesting they couldn't remember which one was dangerous.But those that had been able to run in their youth froze 40 to 50 percent less in both changed box settings.

"The results suggest the amount of physical activity when we're young,at least for rats,has influence on brain and cognitive health—in the form of better memories—when we're older,"says Arthur Kramer of Northeastern University in Boston,who has found that,in humans,exercise promotes the growth of new brain cells.

1.The study shows that_____.

A. physical activity is important for physical health

B. using the running wheels is of benefit to the rats’ growth

C. physical activity can prevent human’s Alzheimer's symptoms

D. the more exercise a rat has when young,the better memory it will possess when older

2.How are Paragraph 3 and 4 mainly developed?

A. By analyzing causes. B. By giving an example.

C. By describing the process. D. By showing differences.

3.What does the underlined word "it" in Paragraph 2 refer to?

A. Exercise. B. Development.

C. Benefit. D. Study.

4.What is the author's attitude towards the animal study?

A. Negative. B. Objective.

C. Critical. D. Doubtful.

Biologists believe that love is fundamentally a biological rather than a cultural construct, because the capacity for love is found in all human cultures and similar behavior is found in some other animals. In humans the purpose of all the desire is to focus attention on the raising of offspring. Children demand an unusual amount of parenting, and two parents are better than one. Love is a signal that both partners are committed, and makes it more likely that this commitment will continue as long as necessary for children to reach independence. But what does science have to say about the notion of love at first sight?

In recent years the ability to watch the brain in action has offered a wealth of insight into the mechanics of love. Researchers have shown that when a person falls in love, a dozen different part of brain work together to release chemicals that trigger feelings of euphoria, bonding and excitement. It has also been shown that the unconditional love between a mother and a child is associated with activity in different regions of the brain from those associated with pair-bonding love.

Passionate love is rooted in the reward circuitry of the brain—the same area that is active when humans feel a rush from cocaine. In fact, the desire, motivations and withdrawals involved in love have a great deal in common with addiction. Its most intense forms tend to be associated with the early stages of a relationship, which then give way to a calmer attachment form of love one feels with a long term partner.

What all this means is that one special person can become chemically rewarding to the brain of another. Love at first sight, then, is only possible if the mechanism for generating long-term attachment can be triggered quickly. There are signs that it can be. One line of evidence is that people are able to decide within a second how attractive they find another person. This decision appears to be related to facial attractiveness, although men may favor women with waist-to-hip ratio of 0.7, no matter what their overall weight is. (This ratio may indicate a woman’s reproductive health.)

Another piece of evidence comes from work by a psychologist at Ben-Gurion University, who found in a survey that a small percentage (11%) of people in long-term relationships said that they began with love at first sight. In other words, in some couples the initial favorable impressions of attractiveness triggered love which sustained a lengthy bond. It is also clear that some couples need to form their bonds over a longer period, and popular culture tells many tales of friends who become lovers.

One might also assume that if a person is looking for a partner with traits that cannot be quantified instantly, such as compassion, intellect or a good sense of humor, then it would be hard to form a relationship on the basis of love at first sight. Those more concerned with visual appearances, though, might find this easier. So it appears that love at first sight exists, but is not a very common basis for long-term relationships.

1.When a person falls in love, _____________.

A. he feels as if he were addicted to cocaine.

B. he will be committed to the beloved as long as necessary.

C. he will experience complex feelings brought on by different regions of his brain.

D. he will experience a calmer attachment form of love before he feels the extreme love.

2.We can infer from the passage that ________.

A. pair-bonding love comes from a long stable friendship.

B. the mechanism for creating long-term attachment ensures love at first sight

C. it is impossible for those ordinary-looking people to fall in love at first sight.

D. men may be attracted by a girl whose figure suggests her admirable reproductive capacity.

3.The underlined word “traits” in the last paragraph probably means ______.

A. characteristics

B. something typical in your temper

C. particular quantities in your personality

D. attitudes that show your moral standards

4.Which of the following may be the best title of the passage?

A. The stages of passionate love

B. The science of love at first sight

C. The biological construct of pair-bonding

D. The mechanism for generating long-term love

One evening I went out with my friends Wang Yi for a meal in a country pub. We left at 9:30 and I was offered to take Wang Yi home.

This morning on my way to school I was deep moved by what I saw outside a bank.An old man was counting his money in the front of the bank.Suddenly a young man came running and knocked him down.To make things bad,his money was lying in all direction.In no time the people around rush to pick the money up while the old man stood there,not know what to do.Surprisingly,everyone gave back the money they had just picked.The old man counted the money again and found that not a single bill was missed.To my great joy,there are now a lot of nice people in your life.It’s true what honesty is more important than money!

In America,when the eighth graders leave the middle school,they are often worried about moving to the high school.It is a hard time for them,but it can be an exciting one as well.To make it easier,students need to get familiar with their school.

Even though they’ve done this already in the middle school,it’s still important to find where their classrooms are.Most schools take students to the high school for a visit at the end of their eighth grade year.And,most schools also have a freshman (新生)speech for parents and students before the first year begins.Sometimes the main office will give away a map of the school.This can help students and parents to find different places in the school.

One way to know your high school more and make new friends is to join a club or play a sport.Schools often offer chances to join different clubs and sports.Fall activities begin in August before the first day of school.If you are not interested in sports,there are clubs for any interest,such as drama,dance,chess,photography,community service,etc.These clubs allow students from different grades.By joining an activity,students can find new friendships,not to mention improving their chances in future college applications(申请).The school office will have a list of activities offered at the school and information on how to join them.

This may be sad to hear, but the number of Britain’s famous red telephone boxes has been falling for decades. The phone box is iconic (标志性的) to foreign fans of Britain and visitors to the country. There are still many left to enjoy, however.

There is deep feeling for the bright red iron-and-glass boxes with the Queen’s coat of arms. The places that still have the red box are mostly small and in the countryside. In these places, the phone box may be a symbol of community, as well as a landmark.

But there are still several cities, including London, that still have original red phone boxes in place.

For tourists, they probably make the perfect background for a selfie (自拍照). Visit London any day in the summer and you’ll see people with their smart phones taking photos with the red box behind them. People who receive the photo will have no trouble guessing where the selfie was taken.

Ever since mobile phones became more widespread, there has been less and less point in public phones. But although the red boxes are no longer popular places to make a call from, new uses are being found for them all the time. The famous design created by Giles Gilbert Scott back in 1924 lives on, but in ways the British architect would never have imagined.

Some of the new ways the phone boxes are being used are quite unusual. For example, some have been changed into tiny coffee shops. Others are hat stores. In one remote area of the country, a red box that had not been used for a long time has been turned into a small lending library.

Even back in their heyday in the last century, phone boxes were put to other uses. Some people even used them as toilets in an emergency.

But for many, they were a safe place to hide if you were caught up in the rain. Britain’s weather is unpredictable: sun one moment, heavy rain the next. So if you are planning to visit the UK and want the perfect British selfie, standing inside a red telephone box in a rainstorm may be your best bet.

1.According to the author, the red phone boxes in Britain are special because .

A. they can be put into different kinds of use

B. they are only found in the British countryside

C. they hold great meaning to some British communities

D. they have a deep connection with the royal family

2.We can learn from the article that British red phone boxes .

A. are mostly made of wood and glass

B. first appeared in big cities such as London

C. were designed by a British architect in the 1930s

D. are not used much for phone calls these days

3.The underlined word “heyday” in the second to last paragraph probably means .

A. a popular time B. a bad time

C. an unusual time D. a happy time

4.The purpose of the last paragraph is to .

A. explain how to deal with Britain’s changeable weather

B. describe a common way of making use of a red phone box in the UK

C. advise visitors to take a selfie standing inside a red telephone box

D. show how to use a red phone box in the case of an emergency
