Man, a land animal. But he is also closely tied to the sea. Throughout history the sea has served the needs of man. The sea has provided man with food and a convenient way to travel to many parts of the world. Today, nearly two-thirds of the world’s population live within 80 kilometers of the sea coast.
In the modern technological world, the sea offers many resources to help mankind survive. Resources on land are beginning to be used up. The sea, however, still can be hoped to supply many of man’s needs.
The list of riches of the sea yet to be developed by man’s technology is big. Oil and gas explorations have been carried out for nearly 30 years. Valuable amounts of minerals exist on the ocean floor ready to be mined.
Fish farming promises to be a good way to produce large quantities of food. The culture of fish and shellfish (贝类动物) is an ancient skill practised in the past mainly by Oriental people, including people in China.
Besides oil and gas, the sea may offer new sources of energy. Experts believe that the warm temperature of the ocean can be used in a way similar to the steam in a steamship. Ocean currents and waves offer possible use as a source of energy.
Technology is enabling man to explore ever more deeply under the sea. The development of strong, new materials has made this possible.
The technology to harvest the sea continues to improve. Experts believe that by the year 2020 the problems that prevent us from exploiting（开发） fully the food, minerals, and energy sources of the sea will be largely solved.

| A．fish and oil |

| C．the problems that prevent us from using the food, minerals, and energy sources of the sea have already been solved. |
| D．by the year 2020, the technology will be good enough to exploit all the sea resources |
A．the people in Asia | B．African people |
| C．European people | D．American people |
| A．Sea Harvest | B．Sea Food |

e years ago if you made a trip to the local library and searched for articles on globing warming, you’d probably come up with a few from the leading magazines in the world. As an Internet search on global warming now shows, the subject has become as rooted in people’s mind as Madonna or microwave cooking.
With the possible exception of another world war, a giant planet, or an incurable disease, global warming may be the largest danger to our planet. For decades human factories and cars have sent billions of tons of greenhouse gases into the atmosphere, and the climate has begun to show some signs of warming. If steps are not taken soon to reduce the amount of carbon dioxide sent into the atmosphere, the result could terribly affect human life. We have already seen growing destruction, such as drought and death in Sudan, flooding in Asia, bush fires in Indonesia, and fierce winter storms in central Europe.
The Republic of Maldives is barely above sea level. Its 250, 000 citizens are scattered across 1,200 islands in the Indian Ocean. A strong typhoon could spell the end for the entire country, as sea levels could continue rising. The entire population would have to be moved away as the country disappears under the sea.
The greenhouse effect is a naturally occurring phenomenon that keeps our planet at a comfortable temperature averaging 60°F. Since the mid-nineteenth century, however, carbon dioxide in the atmosp
here has increased nearly 30% because of the increased use of fossil fuels to run cars, heat homes and power factories. Without controlling, the amount of carbon-dioxide by 2100 may increase by 30%-150% and could lift the average global temperature by up to 2.5° F the next 50 years.
【小题1】.
With the first paragraph, the author intends to .
| A．scold people for not paying enough attention to global warming |
| B．draw people’s attention to global warming |
| C．how to search for the articles on global warming |
| D．point out the serious effect of global warming |
Global warming could affect human life in the following ways EXCEPT .
| A．producing more greenhouse gases | B．causing more floods |
| C．making winter storms fiercer | D．starting more bush fires |
The Republic of Maldives .
| A．has moved away their citizens |
| B．will be more likely to be destroyed by a strong typhoon than by the rising sea level |
| C．is mostly likely to be destroyed by the rising sea level |
| D．will have to move away most of their population |
. Why is the Republic of Maldives especially mentioned in the passage?
| A．Because smaller countries are easier to be affected by global warming. |
| B．Because seaside countries are in danger of disappearing. |
| C．Because it’s necessary to rescue a country before the sea level rises. |
| D．Because the serious result of global warming could end a whole country. |
