A rich man was once riding along the road and saw an old man digging in his garden. On the ground lay a young tree, ready to be planted. The rich man called out to the old man, “What kind of tree are you planting there, my good man?”

“This is a fig(无花果) tree, sir. ” He said.

“A fig tree?” the rich man was very surprised, “Why, how old are you, may I ask?”

“I am ninety years old.”

“What!” cried the rich man, “You’re ninety years old. You are planting a very young tree now and it’ll take years to give fruit. You certainly don’t hope to live long enough to get any fruit from this tree. ” The old man looked around the garden. Then he said with a smile, “Tell me, sir. Did you eat figs when you were a boy? ”“Sure,” the man did not know why he asked this question. “Then tell me this,” he said, “Who planted the fig trees?” “Why-why? I don’t know.” “You see, sir.” went on the old man,“Our forefathers(祖先) planted trees for us to enjoy and I am doing the same for the people after me.”

The rich man was quiet and said, “You are right，my good man. We should do some things for the people after us. Thank you very much.”　 Then he rode away.

6. When do many students pay back their loans from the government?

They pay them back_______________.

B

Some people want to be shot into space after their death, others want to lie deep under the sea. But most people want to go into the freezer(冷藏库).These are believers in cryogenics(低温冷冻学).

Now some diseases can’t be cured, but they may be cured sometime in the future. So some people hope that their bodies can be frozen after they die. When a cure is found, warm up his or her body, bring it back to life and take the cure. Once the body is frozen, it is kept in liquid nitrogen(液态氮) at a temperature of 328 degrees below zero.

Now around a thousand people are going to take cryogenic treatment(处理), though most scientists say it won’t work. If we freeze huge creatures(生物) like humans, every one of their cells(细胞) will be broken. Can they be brought back to life in the future?
