He decided to spend a week's holiday in a quiet village where he could go swimming or fishing. He got off at a small railway station and soon got to a quiet village. He took a room hotel and went to sleep as soon as he had a good meal.At first Mr. Zhang enjoyed himself there. He could do everything he wanted and went wherever he liked.

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.(1).British people _______ invite friends to their home.A.oftenB.alwaysD.never(2).If your British friend invites you to his home, you can ____.A.see anything you likeB.ask how much his house isC.ask the cost of any of the items in itD.only see the downstairs that you are invited into(3).When you show your interest and pleasure in American people’s house, they may be __.A.angryB.happyC.sadD.worried(4).What does the underlined “engage in” mean in Chinese?A.陷入B.参与C.回避D.限制(5).What’s the main ide a of the passage?A.Some manners on visiting British and American people’s home.B.Different table manners between British and American people.C.Different ideas about the home between British and American peopleD.Different ideas about how to get along well with neighbors between British and American people正确答案: (1).C (2).D (3).B (4).B (5).A4. If you’re into sports, you’ve seen it happen—tennis players jump over the net to shake hands after a hard match; football players exchange jerseys（运动衣）after ninety minutes of knocking each other around; even boxers touch gloves at the beginning of each round. Players in every event, from spelling bees to golf，act in this way. It’s all part of sportsmanship（体育精神），a great tradition in sports and competition. It means playing and being calm all through the match.Everyone feels great when they win. In the last few years, you might see some players celebrate a goal with a long victory dance or talk big about their ability. However, it’s always hard for people to say in public that they made a bad play. Good sportsmanship is what they really need. It’s the golden rule of sports.Good sportsmanship means that you play by the rules, talk politely to everyone during games and stay cool even when you lose the game. At the school sports meeting, for example, it’s more important for you to know how to work as part of a team and cheer your teammates on. That may help you enjoy more success at your future work. In competition—as in life—you may not always win, but believe me, sportsmanship will help you get through, and there is always the next match.(1).What match do you know will last ninety minutes?A.TennisB.FootballC.GolfD.Spelling(2).The underlined word “bees” in the passage means ______.A.flypetitionC.guessD.research(3).Why do you think good sportsmanship is really important?A.It’s all part of sports.B.It’s all part of celebration.C.It’s the golden rule of sports.D.It’s how to stay cool.(4).Winning the game will make it possible for players to _______.A.celebrate a goalB.exchange jerseysC.shake handsD.feel great(5).The passage mainly tells us that sportsmanship gets you through no matter whether _______.A.you win or loseB.you play or learnC.you are happy or notD.you feel hard or not.正确答案: (1).B (2).B (3).C (4).D (5).A。
