When we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.
People who are near-sighted can only see things that are very close to their eyes, and everything else seems blurry (="unclear)." Many people who do a lot of work, such as writing, reading and sewing become near-sighted.
People who are far-sighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm’s length. If they want to do much reading, they must get glasses, too.
Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people’s eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.
Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle. To prove this to yourself, look at an object out of one eye; then look at the same object out of your other eye. You will find the object’s relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.When things far away seem indistinct(模糊不清) , one is probably____.
| A．near-sighted | B．far-sighted |
| C．astigmatic | D．suffering from cataracts |
The underlined word suffer in the third paragraph probably means_____.
| A．experience | B．imagine |
| C．feel pain | D．are affected with |
Having two eyes instead of one is particularly useful for______.
| A．seeing at night | B．seeing objects far away |
| C．looking over a wide area | D．judging distances |
People who suffer from astigmatism have______.
| A．one eye bigger than the other |
| B．eyes that are not exactly the right shape |
| C．a difficulty that can be corrected by an operation |
| D．an eye difficulty that cannot be corrected by glasses |
Cleverness is a gift while kindness is a choice.Gifts are easy—they’re given after all.Choice can be hard.
I got the idea to start Amazon 16 years ago.I came across the fact that the Internet usage was growing at 2300 percent per year.I’d never seen or heard of anything that grew that fast，and the idea of building all online bookstore with millions of titles was very exciting to me. I had just turned 30 years old，and I’d been married for a year.I told my wife MacKenzie that I wanted to quit my job and go to do this crazy thing that probably wouldn’t work since most start-ups don’t and I wasn’t sure what to expect.MacKenzie told me I should go for it.As a young boy，I’d been a garage inventor.I’d always wanted to be all inventor，and she wanted me to follow my passion.
I was working at a financial firm in New York City with a bunch of very smart people and I had a brilliant boss that I much admired.I went to my boss and told him I wanted to start a company selling books on the Internet.He took me on a long walk in Central Park，listened carefully to me，and finally said，“That sounds like a really good idea，but it would be an even better idea for someone who didn’t already have a good job.”That 1ogic made some sense to me，and he convinced me to think about it for 48 hours before making a final decision.Seen in that light,it really was a difficult choice，but finally，I decided I had to give it a shot.I didn’t think I’d regret trying and failing.And I suspected I would always be haunted by a decision to not try at all.

Space is a dangerous place, not only because of meteors (流星) but also because of rays from the sun and other stars. The atmosphere again acts as our protective blanket on earth. Light gets through, and this is necessary for plants to make the food that we eat. Heat, too, makes our environment endurable. Various kinds of rays come through the air from outer space, but enormous quantities of radiation from the sun are screened off. As soon as men leave the atmosphere they are exposed to this radiation but their spacesuits or the walls of their spacecraft, if they are inside, do prevent a lot of radiation damage.
Radiation is the greatest known danger to explorers in space, The unit of radiation is called “rem” Scientists have reason to think that a man can put up with far more radiation than 0.1rem without being damaged; the figure of 60 rems has been agreed on. The trouble is that it is extremely difficult to be sure about radiation damage. A person may feel perfectly well, but the cells of his or her sex organs may be damaged, and this will not be discovered until the birth of deformed children or even grandchildren. Missions of the Apollo flights have had to cross belts of high radiation and , during the outward and return journeys, the Apollo crew accumulated(积累) a large amount of rems. So far, no dangerous amounts of radiation have been reported, but the Apollo missions have been quite short. We simply do not know yet how men are going to get on when they spend weeks and months outside the protection of the atmosphere, working in a space laboratory. Drugs might help to decrease the damage done by radiation, but no really effective ones have been found so far.In which way is the atmosphere necessary to man according to the first paragraph?
| A．It screens off the falling meteors. |
| B．It provides enough light for plants to grow. |
| C．It supplies the heat necessary for human survival. |
| D．It protects him against the harmful rays from space. |
We know from the passage that .
| A．exposure to even tiny amount of radiation is fatal( 致命的) |
| B．the effect of exposure to radiation is slow in coming |
| C．radiation is avoidable in space exploration |
| D．astronauts in spacesuits needn’t worry about radiation damage |
The underlined word “deformed” probably means .
| A．badly-shaped | B．weak |
| C．naturally-grown | D．ugly |
It can be inferred from the passage that .
| A．the Apollo mission was very successful |
| B．astronauts will have deformed children or grandchildren |
| C．protection from space radiation is no easy job |
| D．radiation is not a threat to well-protected space explorers |
Dear College Dean,
It is my understanding that this college has received a large donation to be used to enhance (improve) the quality of life for students: expand the bookstore or add computers to the computer lab. It is the tradition of this school to promote education and to be the pioneer of new technology. That is why I strongly argue in favor of the addition of more computers to the computer lab.
Although expanding the campus bookstore to include CDs, gifts, and a snack bar will give a nicer look to the college, we have to think about a greater goal and a more practical way to enhance the quality of life for students. What do we .want for our students and our college? Do we want our college to be known as a place with a great bookstore where you can find CDs and gifts, or as a place where the students can explore and research in their field using the best tools provided by technology? In addition, there are already several snack bars on campus, and there are music stores nearby, so students do not depend on the college bookstore for these things.
We live in a highly technological world and computers play an increasingly important role in how we live. As a learning institution, this college has the responsibility to offer its students the best technology to help them prepare for their future. Many students will be expected to be familiar with the latest software and other tools when they go on to work or to graduate school.
While they are in college, students find they are expected to use computers. Many professors expect students to use computers to do homework or to complete projects. Since students are competing for good grades, those who have limited access to computers are at a great disadvantage. Furthermore, being able to do projects using the computer enhances the process of learning.
If there are more computers, no more will students have to wait in line while scanning the room for an empty chair and computer.. No longer will they have to sit and wait while an outdated computer struggles to follow their commands. Having more new and faster computers available will enable students to finish their work more quickly.
The more computers are used in society, the more colleges will depend on them as a tool of teaching and learning. Making computers more available to students facilitates their learning process by making the process easier, more interesting, more engaging, and in the process enhancing their quality of life.From the passage we can infer that .
| A．present computers in the college cannot meet the demands of the students |
| B．computers in the college will be updated to meet the students’ demands soon |
| C．the college has the responsibility to help the students to prepare for their future |
| D．it is also necessary to expand the college bookstore by using part of the donation |
In paragraph 4，the author mainly wants to tell us that .
| A．computers are beneficial to students’ academic(学业) success |
| B．computers are helpful to students competition for success |
| C．students find it convenient to do assignments by using computers |
| D．students wish to use the money to buy more advanced computers |
Which of the following shows the organization of the passage?
CP: central point SP: sub-point(次要点) P: point C: conclusion
Louis Armstrong had two famous nicknames. Some people called him Bagamo. They said his mouth looked like a large bag. Musicians often called him Pops, as a sign of respect for his influence on the world of music.
Born in 1901 in New Orleans, he grew up poor, but lived among great musicians. Jazz was invented in the city a few years before his birth. Armstrong often said, “Jazz and I grew up together.”
Armstrong showed a great talent for music when he was taught to play the cornet (短号) at a boy’s home. In his late teens, Armstrong began to live the life of a musician. He played in parades, clubs, and on the steamboats that traveled on the Mississippi River. At that time, New Orleans was famous for the new music of jazz and was home to many great musicians. Armstrong learned from the older musicians and soon became respected as their equal. In 1922 he went to Chicago. There, the tale of Louis Armstrong begins. From then until the end of his life, Armstrong was celebrated and loved wherever he went. Armstrong had no equal when it came to playing the American popular song.
His cornet playing had a deep humanity and warmth that caused many listeners to say,“Listening to Pops just makes you feel good all over.” He was the father of the jazz style and also one of the best-known and most admired people in the world. His death, on July 6, 1971, was headline news around the world.Armstrong was called Pops because he .
| A．looked like a musician |
