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.

A. But what if your pants or jacket or bag could charge your phone, or laptop or anything else?

B. The fabric is developed by Intelligent Textiles.

C. Imagine having jeans that charge your phone just by putting it in your pocket.

D. It is a lot different from having to remember to plug in your phone.

E. And that's all great, but would this ever be made it into your home, and charge your phone or laptop someday?

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.
