Early one morning, more than a hundred years ago, an American inventor called Elias Howe finally fell asleep. He had been working all night on the design of a sewing machine but he had run into a very difficult problem: It seemed impossible to get the thread to run smoothly around the needle. Though he was tired, Howe slept badly. He turned and turned. Then he had a dream. He dreamt that he had been caught by terrible savages whose king wanted to kill him and eat him unless he could build a perfect sewing machine. When he tried to do so, Howe ran into the same problem as before. The thread kept getting caught around the needle. The king flew into the cage and ordered his soldiers to kill Howe. They came up towards him with their spears raised. But suddenly the inventor noticed something. There was a hole in the tip of each spear. The inventor awoke from the dream, realizing that he had just found the answer to the problem. Instead of trying to get the thread to run around the needle, he should make it run through a small hole in the center of the needle. This was the
simple idea that finally made Howe design and build the first really practiced sewing machine.
Elias Howe was not the only one in finding the answer to his problem in this way.
Thomas Edison, the inventor of the electric light, said his best ideas came into him in dreams. So did the great physicist Albert Einstein. Charlotte Bronte also drew in her dreams in writing Jane Eyre.
To know the value of dreams, you have to understand what happens when you are asleep. Even then, a part of your mind is still working. This unconscious(无意识的), but still active part understands your experiences and goes to work on the problems you have had during the day. It stores all sorts of information that you may have forgotten or never have really noticed. It is only when you fall asleep that this part of the brain can send messages to the part you use when you are awake. However, the unconscious part acts in a special way. It uses strange images which the conscious part may not understand at first. This is why dreams are sometimes called “secret messages to ourselves”. ( ) 40. According to the passage, Elias Howe was________.
A. the first person we know of who solved problems in his sleep
B. much more hard-working than other inventors
C. the first person to design a sewing machine that really worked
D. the only person at the time who knew the value of dreams ( ) 41.The problem Howe was trying to solve was________.
A. what kind of thread to use
B. how to design a needle which would not break
C. where to put the needle
D. how to prevent the thread from getting caught around the needle
( ) 42.Thomas Edison is spoken of because________.
A. he also tried to invent a sewing machine
B. he got some of his ideas from dreams
C. he was one of Howe’s best friends
D. he also had difficulty in falling asleep
( ) 43. Dreams are sometimes called “secret messages to ourselves” because___.
A. strange images are used to communicate ideas
B. images which have no meaning are used
C. we can never understand the real meaning
D. only specially trained people can understand them

Soon computers and other machines will be able to remember you by looking at your eyes! The program works because everyone’s
eyes are different. So in the future you won’t have to remember a number when you want to use a machine or take money out of a bank. You’ll just have to look at the machine and it will be able to tell who you are.
The eye-recognition (眼睛识别)program is already being tested in shops and banks in the USA, Britain, Spain, Italy and Turkey. Soon this technology (技术)However, scientists are also working on other systems(系统). Machines will soon be able to know you from the shape of your face or hand or even your smell! We already have machines that can tell who you are from your voice or the mark made by your finger.
Eye-recognition is better than other kinds because your eyes don’t change as you get older, or get dirty like hands or fingers, and even twins have different eyes. So the eye-recognition program can be up to 94% correct, depending on how good the technology is. Some programs may only be right 51% of the time. In Britain, it was found that 91% of people who had tried it said that they liked the idea of eye-recognition.
In the future your computer will be looking you in the eye. So smile!
( ) 44. How does the eye-recognition program work?
A. You write your number.
B. You show your ID card.
C. You look at the machine.
D. You say your name.
( ) 45. Why can the program be up to 94% correct?
A. Because eyes never change.
B. Because hands or fingers can get dirty.
C. Because people like the idea of the program.
D. Because the program is widely used around the world.
( ) 46. Which of the following is true?
A. The program is being tested in Japan.
B. Machines with other systems can also tell who you are.
C. 91% of people like the idea of the program.
D. Computers can remember you by looking at your clothes. ( ) 47. What does the underlined phrase “take the place of” in paragraph 2 mean?
A. 拿走
B. 取代
C. 发生
D. 安置

The greatest recent changes have been in the lives of women. During the twentieth century there was an unusual shortening of the time of a woman’s life spent in caring for children. A woman marrying at the end of the 19th century would probably have been in her middle twenties, and would be likely to have seven or eight
children, of whom four or five lived till they were five years old. By the time the youngest was fifteen, the mother would have been in her early fifties and would expect to live a further twenty years, during which custom, chance and health made it unusual for her to get paid work. Today women marry younger and have fewer children. Usually a woman’s youngest child will be fifteen when she is forty-five and is likely to take paid work until retirement at sixty. Even while she has the care of children, her work is lightened by household appliances and convenience foods.
This important change in women’s way of life has only recently begun to have its full effect on women’s economic position. Even a few years ago most girls left school at the first opportunity and most of them took a full-time job. However, when they married, they usually left work at once and never returned to it. Today the school-leaving age is sixteen, many girls stay at school after that age, and though women tend to marry younger, more married women stay at work at least until shortly before their first child is born. Many more after wads, return to full or part-time work. Such changes have led to a new relationship in marriage, with both husband and wife accepting a great share of the duties and satisfaction of family life, and with both husband and wife sharing more equally in providing the money and running the
home, according to the abilities and interest of each of them. ( ) 48.We are told that in an average family about 1890________.
A. many children died before they were five
B. the youngest child would be fifteen
C. seven of eight children lived to be more than five
D. four or five children died when they were five
( ) 49. When she was over fifty, the late 19th century mother________.
A. would expect to work until she died
B. was usually expected to take up paid employment
C. would be healthy enough to take up paid employment
D. was unlikely to find a job even if she is now likely
( ) 50. Many girls, the passage says, are now likely to ________.
A. marry so that they can get a job
B. leave school as soon as they can
C. give up their jobs for good after they are married
D. continue working until they are going to have a baby
( ) 51. According to the passage, it is now quite usual for women to ________.
A. stay at home after leaving school
B. marry men younger than themselves
C. start working again later in life
D. marry while still at school

WINTER break! Two whole weeks without homework -two whole weeks of heaven. Two weeks to relax. I imagined myself getting plenty of sleep. I planned on reading "The Giver", which I hadn't had time to read.
But soon I noticed something: I couldn't sleep. It would be 12:30 am and I would be trying to fall asleep. I would begin thinking that I haven't done anything today!
This happened the next night, and the night after. During the day, when I had free time, I would be pacing (踱步) around the room moaning (抱怨) that I had nothing to do! I was eating when I wasn't hungry. I was playing a computer game even though it was boring.
The truth, I concluded(总结), is that relaxation doesn't mean doing nothing. Relaxation means doing something enjoyable. I planned to swim at the local high school. I set up a practice schedule of an hour and a half per day. I decided to read two books that my friend had recommended (推荐) to me. I planned to do a little community(社区) service work, volunteering to help at the nearby old people's home for two hours every day. After doing those things, writing e-mails to my friends, watching DVDs
and sleeping 12 hours a day, my days are full. And I'm truly enjoying myself relaxing.
Of course, some of my earlier wishes have come true. Being free from schoolwork has taken a load off my mind, helped me to get in perspective (洞察力) and brought me back in touch with my family and myself. Getting so much sleep has done wonders for my state of mind.
After each past winter break, I haven't been able to say what I did, how I used my time. This winter break will be different. I am relaxing by working.
( ) 52. According to the passage, the writer had his/her vacation .
A. for a month
B. for one week
C. for two weeks
D. for six weeks ( ) 53. What was the writer's problem after a few days?
A. He had no books to read.
B. He couldn't fall asleep at night.
C. He played too many computer games.
D. He was always hungry.
( ) 54. What did the writer do at first during his/her winter vacation?
A. He/She paced around the room.
B. He/She moaned and ate.
C. He/She played a computer game.
D. All the above.
( ) 55. What does relaxation mean to the writer finally?
A. Doing nothing at all.
B. Getting 15 hours of sleep every day.
C. Filling the days with fun things.
D. Reading books all day long.
