【題目】閱讀理解
On a cold winter day, many years ago, a French art teacher named Pierre Chevalier got on a train in Lyon to go to Paris. When he started his journey, he didn't know that it was the beginning of almost 40 years of accidents and near death experiences.
During the journey, the train fell into an icy river, killing 12 passengers. Chevalier managed to swim back to the river bank. He only had a broken leg.
Two years later, Chevalier was on a plane from Paris to Moscow when a door suddenly opened and he fell out. A few minutes later, the plane crashed(墜毀); 27 people were killed. Chevalier was so lucky that he landed in a haystack(干草堆).
A few years later, he was hit by a bus, but again had no serious injuries. Then a year after that, he was driving on a mountain road when he saw a truck coming straight at him. He drove the car off the road, jumped out, landed in a tree—and watched his car fall 100 metres down the mountain.
“There are two ways you can look at it,” Chevalier said. “I'm either the world's unluckiest man, or the world's luckiest.” When a reporter asked Chevalier what he thought, he chose the “l(fā)uckiest” one.
Two years ago, aged 71, Chevalier bought his first lottery ticket(彩票) in 50 years and won more than 2 million.
After this, a TV company in America said they wanted him to make an advertisement. At first he accepted, but then he changed his mind. Chevalier said he wouldn't fly to Los Angeles for the filming, because he didn't want to push his luck. Who knows? If he had accepted the invitation, maybe he would have had another accident. But Mr Chevalier is a lucky man. If he'd had another accident, he probably would have survived that too!
（1）In the train accident many years ago, Chevalier ________．
A.didn't get injured at all
B.was lucky enough to be alive
C.was finally pulled out of the river
D.was the only passenger to survive
（2）Why did Chevalier refuse to make the advertisement?
A.Because he had won 2 million.
B.Because he didn't want to leave home.
C.Because he didn't want to risk his life.
D.Because he didn't like the TV company.
（3）The text mainly talks about ________．
A.a man with nine lives
B.the unluckiest man in the world
C.a man who traveled around the world
D.a man who earned 2 million in a lottery

One of the most important things in the world is friendship. In order to have friends, you have to be a friend. But how can you be a good friend at school?
Listen — Listen when they are talking. Don't say anything unless they ask you a question. Sometimes it's not necessary for you to have anything to say; they just need someone to talk to about their feelings.
Help them — If your friend is ever in need of something, be there to help them. You should try to put them first, but make sure you don't do everything they want you to do. Try to take an extra (額外的) pencil or pen with you to classes in case (以防) they forget one. Have a little extra money in your pocket in case they forget something they need.
Be there for them — Try to make something for your friend to help make them feel better in hard times. Making cards and encouraging them are among the nicest things you can do for a friend. Marilyn Monroe, a famous U.S. actor, once said, “I often make mistakes. Sometimes I am out of control. But if you can't stay with me at my worst, you are sure not to deserve (值得) to be with me at my best.” Always remember this! If you don't want to stay with your friends when they're in hard times, then you don't deserve to be with them when they're having a good time!
______ — Try to make plans with your friends. Go shopping, go for ice cream, have a party, go to a movie and so on. Take time to know each other even better by doing something you both enjoy. By planning things together, you both can have a good time. And you'll remember these things when you're all old!
（1）While your friend is talking to you about his or her feelings, you should _____.
A.give him or her some advice
B.just listen unless asked

D.share your feelings as well
（2）When we provide help for our friends, we should _____.

C.change their bad habits first
D.ignore their faults
