【题目】Man still has a lot to learn about the most powerful and complex part of his body — the brain.

It may be surprising to learn that it isn’t age that makes you lose your memory. The reason could be that you have a "lazy" memory, not an old one. Like your body your memory improves with exercise. Once given plenty of exercise, the brain keeps its power. Before discussing how to improve the memory, let’s look at how the brain works. There are two sides to the brain, the left and the right. The right side deals with the senses (what we see, hear, feel and smell). It's the creative and imaginative side. The left side is concerned with logic. It analyzes information and puts it in order.

Some recent research suggests that we remember everything that happens to us. The problem most of us has is recalling events. Most forgetting takes place immediately after learning. An hour after learning something new, more than 50% has been forgotten. After a month, 80% has been forgotten, and so on.

This shows revision is very important. If you revise new material you have learnt, you remember much more. So it's of vital importance to revise newly learned material often, and have frequent breaks. We best remember what we learn at the beginning of a learning period and at the point where we stop. After the break, revise what was learned before the break and then continue learning the new material. These breaks should happen every 20 or 45 minutes.

Other experiments have shown the brain needs time to "digest" what has been learned. The time necessary for this is 5 to 10 minutes. After the break, the memory will have absorbed what it has just learned, and more will be remembered. During this period it is important to exercise the right side of the brain, because the left side is used during the learning period. Therefore you should relax. Listening to music, breathing in fresh air, and looking at a picture are all ways of using the other side of the brain. So when you are studying alone, make a plan which shows when to have breaks and to revise newly learned material immediately before you begin studying again. If you do in this way, your memory will improve.

1According to the text, you lose your memory by ________.

A. getting too old B. hardly using your brain

C. working too hard D. using your brain too much

2To fight forgetting effectively, we're advised to ________.

A. go back to what was learned regularly

B. break down materials into small pieces

C. focus on both ends of a learning period

D. take breaks to give the brain a good rest

3During the learning process the brain need breaks to ________.

A. use the right side of the brain

B. revise newly learnt materials

C. take in what has been learnt

D. relax the left side of the brain

4Where is this text most probably taken from?

A. Science fictions. B. Students’ literature.

C. An advertisement. D. A science report.

【题目】Too many people want others to be their friends, but they don't give friendship back. That is why some friendships don't last very long. To have a friend, you must learn to treat your friend the way you want your friend to treat you. Learning to be a good friend means learning three rules: be honest; be generous (宽宏大量的); be understanding.

Honesty is where a good friendship starts. Friends must be able to trust one another. If you do not tell the truth, people usually find out. If a friend finds out that you haven't been honest, you may lose your friend's trust. Good friends always rely on one another to speak and act honestly.

Generosity means sharing and sharing makes a friendship grow. You do not have to give your lunch money or your clothes. Naturally you will want to share your ideas and feelings. These can be very valuable to a friend. They tell your friend what is important to you. By sharing them, you help your friend know better.

Sooner or later everyone needs understanding and help with a problem. Something may go wrong at school. Talking about the problem can make it easier to solve. Turning to a friend can be a first step in solving the problem. So to be a friend you must listen and understand. You must try to put yourself in your friend's place so that you can understand the problem better.

No two friendships are exactly alike (相同的). But all true friendships have three things in common. If you plan to keep your friends, you must practice honesty, generosity and understanding.

【1】Some friendships don't last long because _____.

A. there are too many people who want to make friends

B. those who give others friendship receive friendship from others

C. some people receive friendship but don't give friendship back

D. they don't know friendship is something serious

【2】According to the passage, honesty is _____.

A. something countable

B. the base of friendship

C. as important as money

D. more important than anything else

【3】In the third paragraph, the underlined word 'they' refers to (指) _____.

A. generosity and friendship

B. generosity and sharing

C. your ideas and feelings

D. your clothes

【4】The best title of this passage is _____.

A. How to Be a Friend

B. Honesty Is the Best Policy

C. A Friend in Need Is a Friend indeed

D. Three Important Points in Life

Four Ways to Be a Great Roommate

Having a roommate can be one of the best experiences in college or, easily, one of the worst.

1 Follow these tips to avoid the common mistakes that turn good roommate relationships sour.

◇Talk things out.

Communication is key. If something happens, sit down with your roommate and have a face-to-face conversation. I've seen roommate relationships fall apart because something happens and, instead of talking to each other, the two start complaining about their roommates behind their backs. 2

◇Don't expect to be best friends.

Some roommates become the best of friends, and some don't. Don't put pressure on yourself or your roommate, especially when you first meet. 3 And if your roommate doesn't end up being your best friend, don't worry.

◇Ask before you take.

This applies to food, clothes and anything else. If you want to keep a relationship going, show your roommate that you have respect for what is his or hers by asking first. 4

◇Clean up after yourself.

This should do without saying. Don't be lazy. Or, at least, don't bury your roommate in your clothes and garbage. Most people I've come across in college are messy. 5 But being considerate with where you put your stuff will help you avoid conflict.

A. So you need to think twice before you help your roommates out.

B. This creates nothing but awkward situations and unhappiness.

C. Even if you both agree to share everything, you should still ask.

D. You don't have all the time to clean your room and keep it organized.

E. It all starts with you to have a good relationship with your roommate.

F. Sometime you get stuck with someone who has tons of negative energy.

G. Remember, you're trying to make a new friend, not to scare your roommate away.

【题目】When I lived in Spain, some Spanish friends of mine decided to visit England by car. Before they left, they asked me for advice about how to find accommodation. I suggested that they should stay at “bed and breakfast” houses, because this kind of accommodation gives a foreign visitor a good chance to speak English with the family. My friends listened to my advice, but they came back with some funny stories.

“We didn’t stay at bed and breakfast houses,” they said, “because we found that most families were on holiday.” I thought this was strange. Finally I understood what had happened. My friends spoke little English, and they thought “VACANCIES” meant “holidays”, because the Spanish word for “holidays” is said “vacaciones”. So they did not go to house where the sign outside said “VACANCIES”, which in English means there are free rooms. Then my friends went to houses where the sign said “NO VACANCIES”, because they thought this meant people who owned the house were not away on holiday. But they found that these houses were all full. As a result, they stayed at hotels.

We laughed about this and about mistakes my friends made in reading other signs. In Spanish, the word “DIVERSION” means “fun”. In English, it means that workmen are repairing the road, and that you must take a different road. When my friends saw the word “DIVERSION” on a road sign, they thought they were going to have fun. Instead, the road ended in a large hole.

English people have problems too when they learn foreign languages. Once in Paris when someone offered me some more coffee, I said “Thank you” in French, I meant that I would like some more, however to my surprise the coffee pot was taken away! Later I found out that “Thank you” in French means “No, Thank you”.

【1The author’s Spanish friends wanted advice about _______.

A. some funny English stories

B. finding places to stay in England

C. driving their car on English roads

D. going to England by car

【2】The author suggested that they stay at “bed and breakfast” because _______.

A. it would be convenient for them to have dinners and live

B. it would be much cheaper than staying in hotels

C. they would be able to practice their English in the house

D. there would be no problem about finding accommodation there

【3“NO VACANCIES” in English means _______.

A. no free rooms B. free rooms

C. not away on holiday D. they don’t live

【4】If you see road sign that says “Diversion” in England, you will _______.

A. take the road and you will be excited

B. have a lot of fun and enjoy yourself

C. find that the road is blocked by crowds of people

D. have to take a different road
