( C)

It is a safe energy.

It is a green energy.

It may cause pollution to the air.

It is endless.

As long as the sun shines, the earth will not run out of energy. The sun pours more energy on earth than we can ever use. Most of that energy comes to us as heat and light. Energy from the sun is called solar energy.

Anything to do with the sun is called "solar". The word began with the Roman word for the sun and their god of the sun, who was called Sol. Solar energy is a safe kind of energy. It doesn't make pollution or have dangerous leftovers. That is why scientists and investors are experimenting with ways of harnessing（治理利用）the sun to do some of the jobs fossil fuels have been doing. But to make the sun do work like that, they have to solve some problems. They have to collect the sun's energy. Collecting sunshine is not easy, unless you are a plant. Sunshine is not easy to store, either. You can't fill a tank with it or put it in the wood box. You can not move it through a pipe or a wire. You can not just turn it on.

( D)

A story is told about a soldier who was finally coming home after having fought in Vietnam. He called his parents from San Francisco. "Mom and Dad, I'm coming home, but I've a favor to ask. I have a friend. I'd like to bring him home with me."

"Sure," they replied, "we'd love to meet him."

"There's something you should know," the son continued, "he was injured pretty badly in the fighting. He stepped on a land mine（地雷） and lost an arm and a leg. He has nowhere else to go, and I want him to live with us."

"We're sorry to hear that, son. But, maybe we can help him find somewhere to live."

"No, Mom and Dad, I want him to live with us."

"Son," said the father, "you don't know what you're asking. Someone with such a handicap would be a terrible burden to us. We have our own lives to live, and we can't let something like this interfere with our lives. I think you should just come home and forget about this guy. He'll find a way to live on his own."

At that point, the son hung up the phone. The parents heard nothing more from him. A few days later, however, they received a call from the San Francisco police. Their son had died after falling from a building. The police believed he had killed himself.

The grief-stricken（悲痛欲绝的） parents flew to San Francisco and were taken to the city morgue（太平间） to identify the body of their son. They recognized him, but to their horror they also discovered something they didn't know, their son had only one arm and one leg.
