Sleep is very important. A person who does not sleep dies faster than a person who does not eat. We spend about a third()of our lives in sleep. That’s about 121 days a year!
How much sleep do we need? We are all different. A baby needs 16 hours of sleep every day. Children of 6 to 12 years of age need an average(平均)of 10 to 12 hours of sleep. Teenagers need 9 to 10 hours of sleep. An adult needs an average of 7 to 8 hours a day. There are some people who need only 3 hours of sleep; others need 10 hours of sleep. After the age of 50, the average sleep time goes down to 6.5 hours a day. We need less sleep as we get older.
About one in three Americans has a problem with sleep. Many of these people cannot fall asleep. The name for this problem is insomnia. Some people say, “I didn’t sleep all night.” But that’s not really true. They may sleep lightly and wake up several times. In the morning, they only remember the time they were awake, so they think they were awake all night.
This is not a new problem. Many famous people in history had insomnia. Some of these people had special ideas to make themselves sleep. Benjamin Franklin had four beds. He moved from one to the other to fall asleep. Mark Twain had a different way. He lay on his side across the end of the bed!
小題1:How long do we spend in sleep a year?
A.Less than three months.B.More than five months.
C.About four months.D.Less than 2000 hours.
小題2:If you are thirteen years old, you need at least __________ hours of sleep.

When women sit together to watch a movie on TV, at the same time they usually talk about a lot of subjects, including children, men, careers and what’s happening in their lives. When groups of men and women watch a movie together, the men usually end up telling the women to shut up. Men can either talk or watch the screen---they can’t do both---and they don’t understand that women can. Besides(此外), women think that the point of all getting together is to have a good time and develop relationships--not just to sit there like couch potatoes staring (盯著) at the screen.
During the ad breaks, a man often asks a woman to explain the plot(the story that is told in a novel or play or movie etc.) and tell him where the relationship between the characters is going. He is unable, unlike women, to read the small body language signals that show how the characters are feeling emotionally(情緒上). Since women originally spent their days with the other women and children in the group, they developed the ability to communicate successfully because they want to keep relationships. For a woman, speech continues to have such a clear purpose: to build relationships and make friends. For men, to talk is to connect to the facts.
Men see the telephone as a communication tool for sending facts and information to other people, but a woman sees it as a way of keeping relationship. A woman can spend two weeks on vacation with her girlfriend and, when she returns home, telephone the same girlfriend and talk for another two hours.
There is no convincing(令人信服的)evidence that social conditioning, the fact that girls’ mothers talked them more, is the reason why girls talk more than boys. Psychiatrist Dr. Michael Lewis, author of Social Behaviour and Language Acquisition, conducted experiments that found mothers talked to and looked at baby girls more often than baby boys. Scientific evidence shows parents reply to the brain differences of their children. Since a girl’s brain is better organized to send and receive speech, we talk to them more. As a result, mothers who try to talk to their sons are usually pointed to receive only short complaints in reply.
小題1:While watching TV with others, women usually talk a lot because they ___________.
A.a(chǎn)re afraid of silence with their families and friends
B.can both talk and watch the screen at the same time
C.think they can have a good time and develop relationships
D.have to explain the plot and body language to their husbands
小題2:After a vacation with her girlfriend, a woman would talk to her again on the phone for hours so as to ___________.
A.experience the happy time again
B.keep a close tie with her
C.recommend her a new wonderful place
D.remind her of something forgotten
小題3:What does the writer want to tell us most?
A.Women’s brains are better organized for language and communication.
B.Women love to talk because they are more sociable than men.
C.Men do not like talking because they believe more in facts.
D.Social conditioning is not the reason why women love talking.
小題4:Which of the following would be the BEST title for the passage?
A.Women Are Socially Trained to Talk
B.Talking Keeps Relationships
C.Women Love to Talk
D.Men Talk Differently from Women

A lift is wonderful. It is really only a small room. Rooms usually stay in one place. Lifts travel up and down all day long.
Sometimes a worker stands in the lift. He or she operates it up and down. In modern lifts there is no worker. The people walk in. They know what floor they want. They push a button and the lift goes to that floor. It is all very fast and easy.
Lifts are very important to us. Why? Think about a tall building. Maybe it has twenty floors. Maybe it has fifty or more. Who can walk up all the stairs? Maybe people can climb them one time. Can someone climb thirty floors to an office every day? Can small children walk up to their room on the twenty-fourth floor? Can their mother and father carry food up all those stairs? Of course not.
We can have high buildings because we have lifts. We could not have all the beautiful tall buildings in the world without lifts. They are really wonderful.
小題1:Which of the following is true?
A.A modern lift has no buttons.
B.A modern lift has a worker to operate it.

When I was growing up, I had an old neighbor, Dr. Gibbs. He didn’t look like any doctor I’d ever known. He never invited us to play in his yard, but he was a very kind person.
When Dr. Gibbs wasn’t saving lives, he was planting trees. He owned a large field and wanted to make it a forest.
The good doctor had some interesting ideas about planting trees. He never watered his new trees. Once I asked why. He said that watering plants spoiled them, and that if you watered them, each baby tree would grow weaker and weaker, so you had to make things difficult for them and pick out the weaker trees early on.
He talked about how watering trees made for shallow(淺的)roots, and how trees that weren’t watered had to grow deep roots in search of water under the earth by themselves. Deep roots were very important.
So he never watered his trees. He’d planted an oak and, instead of watering it every morning, he’d beat it with a rolled-up newspaper. I asked him why he did that, and he said it was to get the tree’s attention.
Dr. Gibbs died several years after I left home. Every now and then, I walked by his house and looked at the trees that I watched him plant about twenty-five years ago. They’re very big and strong now. I planted some trees a few years back and carried water to them for whole summer.
After two years of caring too much, whenever a cold wind blows in, they shake a lot.
Every night before I go to bed, I check on my two sons. Mostly I pray(祈禱)that their lives will be easy. But lately I’ve been thinking that it’s time to change my prayer. I know my children are going to face difficulties. There’s always cold wind blowing somewhere, so what we need to do is to pray for roots that reach deep into the brave heart, so when the rains fall and the winds blow, we could face it strongly and won’t be beaten down.
小題1:We know from the passage the doctor           .
A.didn’t know how to plant trees at all
B.wasn’t good at his own medical job
C.had his own ways of planting trees
D.had nothing to do but plant trees
小題2:When Dr. Gibbs said “…pick out the weaker trees early on.”, he meant that          .
A.some weak trees would be easily found out at the beginning
B.he would choose the weak trees to water earlier
C.the weak trees would be sent to his patients later
D.he would not plant weak trees so early anymore
小題3:The passage tells us that the writer      .
A.should beat his trees with a rolled-up newspaper
B.didn’t often water his trees
C.didn’t have a large field
D.took too much care of his trees
小題4:Which can be the best title of the passage?
A.Watering trees
B.Growing roots
C.Doctor and his neighbor
D.Father and his children
