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. Everything else seems blurry. 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 distances as people with two eyes.We should take good care of our eyes________. .
| A．only when we can see well |
| B．only when we cannot see perfectly |
| C．even if we can see wel |
| D．only when we realize how important our eyes are |
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 blurry in the second paragraph probably means_______.
| A．obvious | B．possible | C．clear | D．unclear |
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 |
I have been very lucky to have won the Nobel Prize twice. It is, of course, very exciting to have such an important recognition of my work, but the real pleasure was in the work itself. Scientific research is like an exploration of a voyage of discovery. You are continually trying out new things that have not been done before. Many of them will lead nowhere and you have to try something different, but sometimes an experiment does work and tells you something new and that is really exciting. However small the new finding may be, it is great to think “ I am the only person who knows this” and then you will have the fun of thinking what this finding will lead to and deciding what will be the next experiment. One of the best things about scientific research is that you are always doing something different and it is never boring. There are good times when things go well and bad times when they don’t. Some people get discouraged at the difficult times but when I have a failure, my policy has always been not to worry but to start planning the next experiment, which is always fun.
It is very exciting to make a new discovery. Some people will do the strangest things for this excitement, such as going round the world in a balloon or walking to the North Pole. There are not many new places to explore but there is a lot of new information to be discovered in science and a journey into this unknown area can be much more worthwhile and just as exciting.
I am sometimes asked, “What do you have to do to win a Nobel Prize?” My answer is: “I don’t know. I have never tried.” But I know of one way not to win one. There are some people whose main reason for doing science is to win prizes and they are always thinking about how to do it. Such people don’t succeed. To do good science you must be interested in it and enjoy doing experiments and thinking out problems. And, of course, you must be prepared to work hard and not to be too discouraged by failure.In the writer’s eyes his greatest pleasure in all his lifetime is _______.
| A．to win the Nobel Prize for the first time |
| B．to be awarded the Nobel Prize for the second time. |
| C．in the work itself |
| D．to have a much more important recognition of his work. |
Why did the writer think scientific research to be one of the best things?
| A．You will be able to win the Nobel Prize through the scientific research |
| B．You can make as much money as possible by doing the scientific research. |
| C．You may continue doing with something different and exciting, so you can never be tired of doing the scientific research. |
| D．You can get much more chances of promotion by making the scientific research. |
What would the writer do when he had a failure?
| A．He would forget this failure and start the next experiment. |
| B．He used to be worried about it for several days and never forget it. |
| C．He always gave up his study as the result of the failure. |
| D．He used to think out the reasons and then continue to do it again. |
Which of the following is true according to the passage?
| A．The writer could still keep calm when he heard the news that he had won the Nobel Prize. |
| B．The writer always gave up his courage when he met with some difficulties in the course of his scientific research. |

| D．There are still many exciting places to explore in the world. |
A traveler lost his way and got off the highway to see where he was. As he drove by, he saw rows and rows of pigpens and pigs running in fields. Suddenly, his eyes caught something really strange. It looked like a pig with a wooden leg.
He drove up into the arm, where he met the farmer. “ Excuse me, ” the traveler said. “ I was just driving by and looking at all your pigs, and I just had to stop and ask about it. Tell me, is there really a pig out there with a wooden leg?” The farmer smiled. “ Oh, that would be old Caesar you saw. He’s the finest pig I’ve ever had ---and smart! Well, let me tell you a little about that pig.”
“ One night a couple of years ago I got to drinking and I guess I had more than I should have. I fell down and knocked over a lamp. That started a fire in the house and old Caesar smelled the smoke. He came in the back door, got the wife and kid out, roused me up and got me out. There is no question about it ---- that night old Caesar saved all our lives. You know that I’m not going to forget it too easily.”
“ Why,” the traveler said, “ this is amazing! I have never heard of a pig like this before! This is fantastic! But tell me, how did he get that wooden leg?”

Over a period of time, many habitats (栖息地)change with respect to the types of plants and animals that live there. This change is known as succession.
Succession occurs because plants and animals cause a change in the environment in which they live. The first weeds and grasses that appear on a bare field, for example, change the environment by shielding the soil from direct sunlight. As these plants spread, the ground becomes cooler and more moist than it was originally. Thus, the environment at the ground surface has been changed. The new surface conditions favor the sprouting（产生）of shrubs. As shrubs grow, they kill the grasses by preventing light from reaching them and also enhance (增加)the soil. Pine seedlings (苗)soon take hold and as they grow, they in turn shade out the shrubs. They are not able to shade out oak and hickory (山核桃)seedlings, however, that have found the forest floor suitable. These seedlings grew into large trees that eventually shade out the pines.The best title of this passage is _____.
| A．The Importance of Weeds and Grasses |
| B．The Success of Oak and Hickory |
| C．How Environmental Habitats Change |
| D．Animal and Plant Habitats |
It can be inferred (推理) from the passage that ______.
| A．oak and hickory trees grow taller than pines |
| B．weeds and grasses prefer cold climate |
| C．pines and grasses can exist together |
| D．birds encourage the growth of shrubs |
Which of the following is a stage of succession as described in the passage?
| A．A forest cut down to build an airport. |

My father was Chief engineer of a merchant ship, which was sunk in World War II. The book
Night of the U-boats told the story.
Memories
In September, 1940, my mother, sister and I went to Swansea, where my father’s ship was getting ready to sail. We brought him a family photograph to be kept with him at all times and keep him sail.
Then I remember my mother lying face down, sobbing. She had heard from a friend that the ship had been sunk by a torpedo(鱼雷).
I can remember the arrival of the telegram(电报),which in those days always brought bad news. My grand- mother opened it. It read, “Safe, Love Ted.”
My most vivid memory is being woken and brought down to sit on my father’s knee, his arm in a bandage.
He was judged unfit to return to sea and took a shore job in Glasgow for the rest of the war. For as long as I can remember, he had a weak heart. Mother said it was caused by the torpedoes. He said it was because of the cigarettes. Whichever, he died suddenly in his early 50s.
Ten years later I read Night of the U-boats and was able to complete the story.
Torpedo
One torpedo struck the ship. Father was in the engine room, where the third engineer was killed. He shut down the engines to slow the ship making it easier for it to be abandoned.
By the time he got on deck (甲板) he was alone. Every lifeboat was gone except one which had stuck firm. When he tried to cut it free it swung against the ship, injuring his hand and arm. He had no choice but to jump—still with the photograph in his pocket.
Three days later, he and other survivors were safe in Glasgow. All 23 with him signed the back of the photograph.
In my room is the book and the photograph. Often, glass in hand, I have wondered how I would have dealt with an explosion, a sinking ship, a jump into a vast ocean and a wait for rescue? Lest（以免）we forget, I have some more whisky and toast the heroes of the war.We can infer(推断) that the mother and children went to Swansea ________.

To Chinese immigrants, in the mid-1800s, California was “The Land of the Golden Mountain.” In their homeland they had heard the words, “There’s gold in California.” They sailed 7,000miles to join the gold rush and strike it rich. Between 1849 and 1882, more than 30,000 Chinese came to California. Most were men. They had been farmers in China. They came here to be miners and laborers. They ended up doing many other jobs, too.
Like many other immigrants, they did not plan to stay in America. They came because of their ties to their homeland and their families. They planned to return to China with their fortunes and help their families.
Only a few Chinese gold miners struck it rich. Most picked over the areas that had been mined already. But still, white miners resented the Chinese. Slowly, they drove the “yellow peril” from the mining camps.
By the end of the 1850s, many Chinese returned home. Those who stayed found other jobs.
Few women had come west in the gold rush. The Chinese saw a good business opportunity. They began doing the jobs women would have done. Many became house servants. Many more opened laundries.
The Chinese opened restaurants. Chop suey and show mein are popular Chinese-American dishes. The Chinese probably created these dishes to serve to the white miners. Other Chinese became fishermen, farmers, and even cigar makers. Why did Chinese go to America in the mid-1800s?
| A．Because they could find good jobs there. |
| B．Because they had found gold there. |
| C．Because they could open laundries and restaurants there. |
| D．Because they heard there was gold there. |
The underlined word “resented”(L.2,Para.3 ) mean “________”.
| A．liked | B．helped | C．hated | D．served |
Which should be the title of the passage?
| A．Early Chinese immigrants in America |
| B．Dream to strike it rich |
