二、阅读理解：阅读下面的短文，根据文章内容从A、B、C三个选项中选出一个最佳选项。

Man is 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 impressive. 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 (开采).

Fish farming promises to be a good way to produce large quantities of food. The culture of fish and shellfish is an ancient skill practiced in the past mainly by Oriental people.

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 (水流) 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 2000 the problems that prevent us from exploiting fully the food, minerals, and energy sources of the sea will be largely solved.

1. The major things that the sea offers man are {A; B; C}.

A. fish and oil

B. warm temperature and ocean currents

C. the food, energy sources, and minerals

2. The sea serves the needs of man because {A; B; C}.

A. in provides man with food

B. it supplies man with minerals

C. all of the above

3. We can conclude from this passage that {A; B; C}.

A. the sea resources have largely been used up

B. the sea, in the broad sense, has not yet been developed

C. the problems that prevent us from using the food, minerals, and energy sources of the sea have already been solved.

4. The underlined words _Oriental people_ in the fourth paragraph probably mean {A; B; C}.

A. the people in Asia

B. African people

C. European people

5. The best title for this passage is {A; B; C}.

A. Sea Harvest

B. Technology for Exploiting the Sea

C. Man and the Sea

正确答案是：

二、阅读理解：阅读下面短文，选择合适的内容将短文补充完整。

_____ That's what this material does. It is developed for the British Army. The fabric is made of yarn. The yarn can conduct electricity from a battery pack to anywhere in your clothing. It can charge your gadgets on contact.

_____ It can carry either power or data through a soldier's clothes, helmet, or backpack. It can gear that otherwise needs separate power sources. The materials have been field tested. But they still need to be weather-proofed.

_____ Right now, charging up a battery still involves wires, chargers, and sockets. Inductive charging is developing. But you can not just put your phone down on any surface and start powering up.

_____  And what if that could be hacked together with some kind of inductive charging? You'd be able to almost totally cut the cord with your gadgets. Yes, you'd need to charge up whatever power source you're using now and then. But keep a pair of khakis plugged in while they hang in the closet. _____
