We know more about the surface of the planet Mars than we know about what is at the bottom of Earth’s oceans.
Until recently, scientists had mapped only about 20 percent of the sea floor. But our knowledge of the deep seas is changing because of information from satellites. Scientists have produced a new map that provides a detailed picture of the oceans. The map is expected to help oceanographers, industry and governments.
The new map is twice as detailed as the map made 20 years ago. David Sandwell is a geophysics professor at the Scripps Institution of Oceanography at the University of California. He and other scientists worked on the mapping project. He says they turned to space to look deeper into the ocean. He spoke to VOA on SKYPE.
“The way we’re doing that is to use a satellite altimeter(高度计), a radar to map the topography(地貌) of the ocean surface. Now that seems sort of strange that you’d map the topography of the ocean surface when you really want to get at the sea floor. But, the ocean surface topography has these bumps and dips due to gravitational effects that mimic what’s on the sea floor.”
The scientists collected and studied information from two satellites. Some of the data came from the European Space Agency’s Cryo-2 satellite. It was placed in Earth’s orbit to watch sea ice. The other satellite is the American space agency’s Jason-1. It is studying the surface of the oceans. Scientists combined the satellite data with images gathered by sonar equipment on ships. Sonar works by sending sound waves through the water. When the sound waves hit an object, its presence is confirmed.
“That enables us to look at smaller-scale features and also features that are buried by sediments in the ocean basins.”
The new map shows the sea floor as it has never been seen before. It shows thousands of underwater mountains and places where continents pulled apart. It shows where earthquakes were active many years ago. They all are buried deep underneath the ocean floor.
In one place, three mountain ridges join at the same area. Huge tectonic (构造的) plates can be seen clearly there.The passage is likely to ______________________.

Norman Cousins was a businessman from the United States who often traveled around the world on business. He enjoyed his work and traveling.
Then, after returning to the United States from a busy and tiring trip to the Union of Soviet Socialist Republics( USSR)，Mr. Cousins got sick. Because he had pushed his body to the limit of its strength on the trip, a chemical change began to take place inside him. The material between his bones became weak.
In less than one week after his return, he could not stand. Every move that he made was painful. He was not able to sleep at night.

Americans think that travel is good for you. Some even think it can help to solve one of the country ’ s worst problems ~: crime (犯罪）.
Crime worries a lot of people. Every year, the number of crimes is up and up. And many criminals (罪犯）are young. They often come from sad homes, with only one parent or no parents at all.
There are many young criminals in prison，but prison doesn ’ t change them. Six or seven in ten will go back to crime when they come out of prison.
One man ,Bob Burton, thought of a new idea. In the old days, young men had to live a difficult life on the road. They learned to be strong and brave, and to help their friends to be strong and brave, and to help their friends in time of danger. This helped them grow into men. So Bob Burton started “Vision Quest. “ He takes young criminals on a long ,long journey with horses and wagons (马车）， 3,000 miles through seven states. They are on the road for more than a year.
The young people in Vision Quest all have bad problems. Most of them have already spent time in prison. This is their last chance.
It’s hard work on the road. The day starts before the sun comes up. The boys and girls have to feed the horses. Some of them have never loved anyone before but they love their horses. That love can help them to live a new life.
Not all the young people on Vision Quest will leave crime behind them. Three or four in ten will one day be in prison again. Bob Burton is right. Travel can be good for you. Even today, Americans still say, “ Go west, young men. ”In the last paragraph “leave crime behind them" means .
| A．no longer do a crime | B．leave people who do a crime |
| C．don’t do all the crimes | D．leave criminals behind |
Why is Bob Burton right?
| A．Because he can help to solve crime. |
| B．Because three or four is better than six or seven. |
| C．Because the young criminals have a hard life on the road. |
| D．Because he can stop crime in the country. |
Form the passage we may infer that .
| A．getting up before the sun rises can help out of crime |
| B．we can hardly find a person who has no love for anybody or anything |
| C．travelling can help all criminals out of prison |
| D．young people can do anything freely |
On “ Vision Quest" .
| A．young people have bad problems |
| B．young people grow tall very fast |
| C．young people often help their friends in time of danger |
| D．all of the above |
Americans still say, "Go west, young men. ”because .

| B．in the west there is a prison |
| C．there they have to live a hard life to grow into men |
| D．prison doesn’t change them |

Who are these people rushing by you on the street? More than 250 million people now call America" home" , but most of them can trace their families back to other parts of the world. If you, look at the names on shop windows, you will see that Americans come from many different lands. The idea that these people, who once were strangers to the United States，have lost the customs and cultures of their original countries and have become "Americans"is really not true. In fact, what exists in America is - more often a kind of “ side - by - side" living in which groups of people from other countries often have kept many of their own customs and habits. They join the general American society only in certain areas of their lives such as in schools，business，and sports一but they keep many of their own native customs and manners socially and at home. This “ side - by - side" living has both advantages and disadvantages. Sometimes it may cause disagreements to develop between groups whose ways of life are very different from one another. However, there are also great advantages that come from the variety of cultures brought by settlers from other lands. There is great freedom of choice among ideas ’ dress, food, and social customs in America. Everyone can find some part of his or her own familiar world in the United States, in churches, music, food, national groups, or newspaper.More than 250 million people call America ”home" because .

The bar-tailed godwit （斑尾鷸）has just broken its own record for the world’s longest non-stop flight, including humans in planes, according to a report made by Lund University Press. The bird can fly non-stop for eight days, while the most impressive man-made airplane can only remain in the sky for 82 hours without a stop.
The bar-tailed godwit’s journey, from Alaska to New Zealand, covers over 6,835 miles. It completes this trip twice a year, in autumn going to New Zealand, and in spring back to Alaska. The tireless bird ends the trip without stopping once for food or rest. All other birds can only finish trips that are twice as short as what the bar-tailed godwit travels.
One reason for the bar-tailed godwit’s success is that it has made the best use of its fuel, which is only 0.41 percent of its body weight over each hour of any given long flight. Hedenstrom, a professor from Lund University, says, “This figure is extremely low compared with other birds.” The bird also has a special body shape that helps it fly easily. It stores body fat and protein to manage its trips. It also travels fast, compared to other birds and animals.
Many questions remain about this bird record holder that never gets lost in the air. Researchers wonder whether it has an inside compass (指南针) that helps it to know the direction. Please watch how beautiful bar-tailed godwits look as they come in for a landing, along with other birds.For the flight from Alaska to New Zealand, the bar-tailed godwit__________
| A．doesn’t need to stop to eat |
| B．is afraid of hot weather |
| C．seems very tired at last |
| D．should fly less than 7,000 meters |
The main reason why the bar-tailed godwit can break the record is that it ______.
| A．eats little food every hour |
| B．has a special body shape |
| C．stores much water in its body |
| D．has very light body weight |
The last paragraph tells us that _________.
| A．researchers have understood the bird very well |
| B．the bird has a very good sense of direction |
| C．there are still many who doubt the bird’s ability |
| D．the bird has an inner compass |
