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 (海洋学家), 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 University of California. He and other scientists worked on the mapping project. He says they turned to space to look deeper into the ocean.

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 (声波定位仪) equipment on ships. Sonar works by sending sound waves through the water. When the sound waves hit an object, its presence is confirmed.

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.

David Sandwell says the map is a powerful tool for fisheries, those interested in protecting the environment and for oil exploration.

“The petrol exploration industry is interested in how to reconnect the continents, bring them back together tectonically so you can map the basins on one continental edge—say, Africa—and use that to establish where the similar basin would be on the other continental edge in South America.”

If scientists know that information, they may be able to find oil fields. The new data also will help scientists improve their estimates of ocean depths. This information can help ships travel safely and improve military operations and scientific projects worldwide.

Mr. Sandwell thinks scientists will make many more discoveries as they examine the new map and the information it provides.

1.Which one is not mentioned about the benefits brought by the new map?

A. Fisheries.　　 B. Scientific projects.

C. Ship manufacture.　　 D. Oil exploration.

2.What can we know about the new map?

A. It shows where earthquakes will happen.

B. It will be helpful to industry and governments.

C. It is three times as detailed as the old one years ago.

D. It shows the sea floor as it has ever been seen before.

3.The text is likely to appear in _________.

A. a newspaper　　 B. an advertisement

C. a science magazine　　 D. a finance report

4.Which of the following can be the best title for the text?

A. The detailed picture of the oceans

B. Underwater mountains and places

C. More discoveries about the oceans

D. Scientists create new maps of ocean floor

Buses are celebrating their 100th anniversary. About 80 percent of all public-transport passengers worldwide are carried by buses.

The bus is a very efficient mode of transport, being cheap, flexible, comfortable and, in many cases, tailored to the needs of users both in terms of capacity and speed. Buses operate in mixed traffic, and are easy to put in service.

From an economic, environmental and social point of view, the bus remains the best solution to the problem of achieving balanced and environmentally-friendly urban development. Indeed, the bus is the only mode of public transport in many of the world’s cities, and plays a key supporting role in cities with rail transport.

Over the past decades, increased use of roads by private cars has contributed to terrible traffic problems, affecting the speed of buses as well, and hence their service quality, reliability, energy consumption, and economy. In such circumstances, the efficiency and performance of buses depends heavily on special lanes. Various forms are possible----from a mere painted mark on the road to more expensive variants such as elevated lanes, movable barriers, and “bus locks”.

A related trend is to look beyond vehicle technology alone and to consider the wider system, of which buses are a part, such as the infrastructure(基础设施)and other operational aspects of city. This is commonly known and promoted as the “bus-system approach”. Other key innovations(革新) include clean engines, alternative fuels, and guidance devices. In terms of the designs of buses, much of what has happened to light rail can be transferred to them, including the shapes of the vehicles themselves.

The energy consumption of a bus per passenger is one-sixth that of a car, and buses are only responsible for about 5% of the CO₂ emissions generated by vehicles at present.

1.From this passage we learn that ________ .

A. buses are the most environmentally-friendly of all motorized vehicles

B. buses were first used more than a century ago

C. most passengers prefer trains to buses

D. a bus has a much larger capacity than any other vehicle

2.What has affected the service quality of buses?

A. Unsuitable infrastructure.               B. Private cars.

C. The increasing population of cities.

D. Very rapid urban development.

3.Which of the following is an approach to improving bus service?

A. Improving the speed of buses.

B. Reducing the number of private cars.

C. Setting up special lanes for buses.

D. Increasing the number of buses.

4.From the passage we can infer that in the future________.

A. there will be more buses than today

B. bus engines will need no power

C. buses will be replaced by other means of transport

D. the appearance of buses will change
