The journey two divers made some time ago to the deepest point on the earth makes us realize how much of the world still remains to be studied. The two men went down seven miles to the bottom of the Pacific Ocean inside a small steel ball to find out if there are any ocean currents(水流) or signs of life.

It was necessary to set out early, so that the ball would come to the surface in daylight, and be easily found by the mother ship which would be waiting for it. The divers began preparations early in the morning and soon afterwards, when all was ready, the steel ball disappeared under the surface of the water.

The divers felt as if they were going down steps as they passed through warm and cold layers (层) of water. In time the temperature dropped to the freezing point. They kept in touch with the mother ship by telephone telling how they felt. Then, at a depth of 3,000 feet, the telephone stopped working and they were quite cut off from the outside world. All went well until some four hours later at 30,000 feet, the men were frightened by a loud, cracking noise. Even the smallest hole in the ball would have meant instant death. Luckily, though, it was only one of the outer windows that had broken. Soon afterwards, the ball touched the soft ocean floor raising a big cloud of "dust" made up of small dead sea creatures. Here, powerful lights lit up the dark water and the men were surprised to see fish swimming just above them quite untroubled by the great water pressure. But they did not dare to leave the lights on for long, as the heat from them made the water boil. Quite unexpectedly, the telephone began working again and the faint but clear voices of the divers were heard on the mother ship seven miles away. After a stay of thirty minutes the men began their journey up, arriving three hours later, cold and wet through, but none was worse for their experience.

A boy was walking home from school when he saw a large, tempting(诱人的)apple on one of the branches of an apple tree hanging out over a tall fence. The boy wasn’t much of a fruit-eater, a bar of chocolate if given the choice. , as the saying goes, the forbidden fruit can be tempting. Seeing the apple, the boy wanted it.

The Golden Gate Bridge in San Francisco,California is one of the world's most beautiful bridges. It is also one of the most visited places in the world. Vehicles cross the bridge an average of 41 million times each year. More than 1800 hundred million vehicles have used the bridge since it opened more than 70 years ago.

The bridge was painted “International Orange” because that color went well with the natural surroundings. The color also is easier to see in the heavy fog that often covers the area. But the Golden Gate Bridge was not named for its orange color. It was named for the body of water that it crosses,the Golden Gate Strait.

The Golden Gate Strait is the entrance to the San Francisco Bay from the Pacific Ocean. The Golden Gate Bridge links the city of San Francisco with Marin County,California. Planning for the bridge began in the 1920s when the area around San Francisco was growing. People living in the area needed another way to get to the city besides small ferries(渡船).

Joseph Strauss was the chief engineer for the project. Work began in 1934. Mr.Strauss demanded the strongest safety protections in the history of bridge building. These included the first use of “hard hats” to protect the workers' heads and special glasses to protect their eyes.

A special safety net was suspended(挂) under the bridge. This net saved the lives of 19 men during the construction. However,11 other workers were killed when they fell from the bridge through the net. Still, this was a new safety record for the time.

The Golden Gate Bridge opened in 1937.It extends 1,280 meters across the water. The total length is 2,737 meters. It was the largest suspension bridge(吊桥) in the world until 1964. That is when the Verrazano Narrows Bridge opened in New York City. Today,the Golden Gate Bridge is the ninth longest suspension bridge in the world.

1.The Golden Gate Bridge was named after ________.

A.the local climate

B.the color of a paint

C.the strait it crosses

D.its natural surroundings

2.The purpose of suspending a special safety net is to ________.

A.protect the environment

B.make construction easier

3.What do we know about Joseph Strauss?

A.He attached importance to the workers' safety.

B.His safety measures were not of practical value.

C.He built the first suspension bridge in the world.

D.He demanded strong measures to ensure the safety of the bridge.

4.The passage is written to ________.

A.invite readers to San Francisco

B.introduce the Golden Gate Bridge

C.describe how the Golden Gate Bridge was built

D.tell the story of an engineer called Joseph Strauss

The cultures of the East and the West really distinguish from each other a lot. This is because the culture systems are two ____ systems on the whole.

The origin of the eastern culture is mainly from two countries: China and India. Both of the two cultures are gestated(孕育) by ____. In China, the mother river is the Yellow River, ___ the Indian one is the Hindu River. These two cultures have ____ for several thousand years and formed their own styles. Then in Tang Dynasty of China, the Chinese culture ____ went overseas to Japan, ____ into the Japanese society and ____ the Japanese culture nowadays.

Long-time exposure to air pollution can lead to physical changes in the brain and cause trouble in learning and memory, and even anxiety. This is suggested by the results of new research on mice.

While other studies have shown the harmful effects of polluted air in the lungs and heart, this is the first to show the negative effect on the brain.

The team of Laura Fonken, Randy Nelson, from the Ohio State University, USA, has spread to the brain a previous line of research which found that fine particulate (微粒) matter floating in the air mainly because of air pollution caused by humans, causes swelling in much of the body, and may be related to high blood pressure problems, and some other diseases.

In the research Fonken and his colleagues exposed mice to polluted air for six hours each day, five days a week, over a period of 10 months, almost half the average life length of mice.

Polluted air contains fine particles created by cars, factories and natural dust. Fine particles of this kind are tiny, about 2.5 micrometers in diameter, or about one-thirtieth the width of a human hair. These particles can go deep into lungs and other organs.

The concentration of this particulate material to which they exposed mice is equal to the concentration at which people can be exposed in some polluted urban areas.

After a period of 10 months, the researchers got the animals to have a series of behavioral tests. Both the behavior of mice and the results of neurological(神经的) tests done to them show that those within the polluted air had more problems in learning and memory, and higher levels of anxiety.

The results suggest that long-time exposure to polluted air can have measurable negative effects on the human brain and can cause a variety of mental health problems. This could have important consequences for those living and working in polluted urban areas.

1.The results of new research on mice first suggest that polluted air mainly does harm to ________.

A. normal organsB. lungs and heart

C. mental healthD. blood pressure

2.The bad effects of tiny particles in polluted air are those except ________.

A. high blood pressure problems

3.From the last sentence we can infer that people living in polluted urban areas ________.

A. are likely to suffer from mental problems

B. can measure the negative effect on them

C. show little concern for air pollution

D. can be exposed to polluted air longer

4.Which of the following is the best title for the passage?

A. Long-time Exposure to Air Pollution

B. Evidence and Concern of Air Pollution

C. Measurable Effect on Human Brain

D. Mental Problems Caused by Air Pollution
