When you’re invited to have dinner in a foreigner’s home, please remember the following:At table, when the hostess （女主人）picks up her napkin（餐巾），you may pick up yours and put it on your legs.If a servant（佣人）passes food around, he will pass the dish to you at your left hand so that you can easily serve yourself with your right hand. Never serve yourself while the dish is on your right; it is then the turn of your neighbour on the right.Do not reach across the table or in front of someone to get something---that is not polite. Ask him or her to pass it to you.There are things in the middle of the table, such as bread, butter, and candies. You shouldn’t take any until the hostess tells the servant to pass them to you.Do not leave your seat without saying anything. If you need to leave the table to go to the washroom or do something else, you should say “Excuse me for a moment, please.”41. You should put your napkin on your legs before the hostess picks up hers.42. The dish is passed to you on either of your sides.;43.

But they are quite different from almost all land animals. Their brain（大脑）is as big as men’s and they live a long life---- at least 20 or 30 years.Like some animals, dolphins use sounds to help them find their way around. They also use these sounds to talk to each other and to help them find food. They do not use their ears to receive sounds, but use the jaw--- the lower part of the mouth.It is strange that dolphins are friendly to men, and for thousands of years, there are many stories about dolphins and men. In the 19th century, in a dangerous part of the sea near New Zealand, there was a dolphin. The seamen liked him very much and gave him a very good name, Jack. From 1871 to 1903, Jack met every boat in the area and showed it the way. In 1903 a passenger on a boat with the name of The Penguin shot and hurt Jack. Luckily the dolphin didn’t die, and after a long time he was well again. He guided the ships through the area for nine more years, but he refused to help the boat The Penguin.Today, some people still kill dolphins, but many countries in the world now protect them. In these places, people are not allowed to kill them.46. The word jaw means _______ in Chinese.…A. 下颚B. 嘴巴C. 嘴唇D. 鼻子47. How do dolphins find their wayA. They use their noses to smell the way.B.

People always laughed at him. No one showed kindness to him.His only friend was a dog named Tige. He gave his dog enough to eat and drink, but sometimes he was not polite to it. He didn’t know that an unkind work sometimes could cut one’s heart like a knife.(One day as he walked down the street, a young lady was walking in front of him. Suddenly one of her bags dropped from her arms. As she stopped to pick it up, she dropped other bags. He came to help her. “Thank you, dear! You are a nice little boy!”she said kindly, smiling.A special feeling came to him. These were the first kind words he had ever heard. He watched her until she went far away, and then he whistled （吹口哨）to his dog and went directly to the river nearby.“Thank you, dear! You are a nice little boy!”he repeated（重复）the woman’s words. Then in a low voice he said to his dog, “You are a nice little dog!”Tige raised its ears as if it understood.“Uhum! Even a dog likes it!”he said, “Well, Tige, I won’t say unkind words to you any more.”Tige waved its tail happily.The boy thought and thought. Finally he looked at himself in the river. He saw nothing but a dirty boy. He washed his face carefully. Again he looked. He saw a clean nice boy. He was amazed. From then on, he had a new life.After telling this, the businessman stopped for a while, and then he said,“Ladies and gentlemen, this is the very place where that kind woman planted in me the first seed（种子）of kindness. All of us should learn about kindness. What a great power（力量）it has!”51. The boy repeated the words “Thank you, dear! You are a nice little boy!”, because _______.A. he was thinking about the wordsB. he didn’t understand the wordsC. he wanted to talk to his dog。
