(阅读理解) 1: Mr. Green and his wife had a dog. When they went out, they always left the dog inside the house. One evening they wanted to go to the cinema, so they left the dog in the house and locked the door and their garden gate. They went off in their car.
When the film was finished, they went home. They opened the gate and put the car away. When they came to the front door, they found that the glass in the door was broken. The door was not locked and it was open. A robber! They went in and quickly looked in all the rooms to see if the robber had taken their things. However, everything was in the right place and nothing at all was missing.
The dog was sleeping in the sitting-room. The wife was angry with the dog.“Why didn’t you guard the house?”she said. The dog was pleased to see Mr. and Mrs. Green. It began to wag(摇)its tail and then it went to a comer of the room and picked up something in its mouth. It went to the wife and dropped the thing at her feet. When she went to pick it up, she was very surprised. Can you guess what the dog’s present was? It was a man’s finger!
The end of the story is this. Mr. Green telephoned the police and told them everything. Three days later the police caught the robber. They found him easily.
正确答案:
(阅读理解) 2: Eating out is more popular in Britain today than it has ever been. It is reported that British people spend more eating out than cooking for themselves and eating at home. It seems that many British people are becoming more and more interested in how good their food tastes, and also how healthy it is.
However, eating out can also be expensive, so British people do not eat out every night.
When having a date with friends, or having a birthday, many people like to go to a restaurant, and people often also eat in a restaurant before going to the cinema or the theater.
As in all cultures, there are many rules of manners about eating. The knife and fork should be used in the correct way. It is also impolite to speak with your mouth full when you are eating.
Most British cities have a large collection of food as well as British food, from the very cheap to the very expensive－ French, Italian, Indian, Chinese, Thai, Japanese and many, many more.
When people are too tired to cook after work, they often get a “takeaway”. This means that they order from a take－out restaurant by telephone, and then go to get it. Many take-out restaurants also send it to your house. All you have to do is to open the door, pay and eat!
正确答案:
(阅读理解) 3: For the British, the home is private place in which he or she goes to hide away from the troubles of life. It is very seldom that one would be invited to a British person’s home. It is rude to knock on a person’s door if you are not invited. If you are invited, don’t ask to see more than the downstairs that your British host invites you into. Never ask how much the house or any of the items in it cost.
To the American, most of them want their home to be a place where they can entertain (款待) and share their lives with their friends. They may be delighted to give you a full tour of their houses. They may also be pleased when you show your interest and pleasure in their houses.
Both British and American people will engage in quite a bit of chat and a drink or two before the meal is served. After the first mouthful, you should say how delicious the food is and ask something about it. Remember, never eat with your mouth open and make very little noise while eating. It would be nice of you to help your host in any way. Maybe offer to pour some drinks or clear up after the meal.

(阅读理解) 4: Some people think only school children do not agree with their parents, however, it is not true.
Communication is a problem for parents and children of all ages. If it’s hard for you to communicate with your parents, don’t worry about it. Here are some advice for you to bridge the generation gap (代沟).
Don’t argue with your parents. Don’t get to your parents when you are angry. Your parents probably won’t consider your ideas if you are shouting at them. And you can’t express yourself well if you are angry. Go some place to cool off. Make sure you understand why you are unhappy. Then think about what you want to say to your parents. If you don’t think you can speak to them at the moment, try writing a letter.
Try to reach a compromise (和解). Perhaps you and your parents disagree on something. You can keep your disagreement and try your best to accept each other. Michael’s mother didn’t agree with him about buying a motorcycle. They argued over it. But they finally came to a compromise. Michael bought the motorcycle, but only drove it on certain days.
Of course, your parents might refuse to compromise on something. In these situations, it is especially important to show love and respect to them. Showing respect will keep your relationship strong.
Talk about your values. The values of your parents are probably different from those of your own. Tell your parents what you care about, and why. Understanding your values might help them see your purposes in life.
A good relationship with your parents can make you a better and happier person. It is worth having a try!
