One day, an old couple around the age of 70 walked into a lawyer’s office. They were there to get a divorce(离婚). The lawyer(律师) was very puzzled. A  1  having a chat with them, he got their story.
This couple had been quarrelling in their 40 years of marriage and nothing ever seemed to go right. They stayed together because of their children. Now all their children have grown up and have their o  2  families. There’s nothing else the old couple have to w  3  about. All they want is to live their own life, so both have agreed on a divorce.
The lawyer was having a hard time trying to get papers done. He couldn’t understand why the old couple w  4   a divorce. While they were signing the papers, the wife told the husband, “ I really love you, but I really can’t carry on any more.”
“It’s Ok, I understand,” said the husband. Looking at this, the lawyer suggested a d   5   together, just the three of them. The wife thought, why not, since they were still going to be f  6  .
The first dish was roasted chicken. At once, the old man took the chicken leg and gave it to the old lady. “Take this, it’s your f  7  .
Looking at this, the lawyer thought maybe here was a chance, but the wife looked
u  8   when she answered, “This is the problem. You always think so highly of yourself and never think about how I feel. Don’t you know that I h  9  chicken legs?”
Little did she know that, over the years, the husband had been trying many d  10  ways to please her; little did she know that chicken legs were her husband’s favourite.

Have you ever wondered?

1.      Why do airplanes take longer to fly west than east?

It can take five hours to go west-east from New York (NY) to London but seven hours to travel east-west from London to NY. The reason for the difference is an atmospheric phenomenon (大气现象) known as the jet stream (气流). The jet stream is a very high altitude (=" above" sea level) wind which always blows from the west to the east across the Atlantic. So the planes moving at a constant air speed go faster from the west to the east when they are moving with the wind than in the opposite.

2.      What would happen if the gravity on Earth was suddenly turned off?

Supposing we could magically turn off gravity. Would buildings and other structures（建筑物）float away? What happened would depend on (依靠) how strongly the things were attached (吸附) to the earth. The earth is moving at quite a speed, moving at over a thousand miles per hour. If you turn something around your head on a string, it goes around in a circle until you let go of the string. Then it flies off in a straight line. ‘Turning off’ gravity would be like letting go of the string. Things not attached to the earth would fly off in a straight line. People in buildings would suddenly shoot upwards at a great speed until they hit the ceiling (=" top" surface of a room). Most things outside would fly off into space.
