They sat there and talked the whole day. Once the three ladies quarreled(争吵). One of them said. “Look, how white and beautiful my hands are!”Another one said, “My hands are more beautiful.” The third one said, “Mine are the most beautiful ones.” An old beggar（乞丐）woman came up to them. “Beautiful ladies,” she said, “I’m hungry. Please give me something to eat.”But the three ladies gave her no thing. They only asked, “Tell me, old woman, which one of us has the most beautiful hands?”A peasant（农民）woman was also sitting by the river. She was poor and her hands were rough（粗糙的）because of hard work. The old woman came up to her and said, “I’m hungry. Please give me something to eat.” The peasant woman took out her only cake she had and gave her a half.The old woman ate it and drank some water.

Now a new study suggests it really brings lasting health advantages. Those who had a hard time getting over daily troubles had more physical health problems ten years later.If you are likely to think over daily troubles--running through every "what if" and "if only"-- it makes you feel that's a big deal. Maddux said, “You probably find you feel even worse after a night of thinking. If that cycle is repeated over time, it will wear you down."The study results are based on 1,155 people who took in a national health study. Each day, the people described their feeling changes over the past 24 hours. During the 10-year mark, only 17 percent of the people have no physical health problems, and only 20 percent are satisfied with their physical strength. But those who always say they have negative feelings because of daily troubles are more likely to have the physical problems, the finding showed.People can be likely to have bad feelings for a longer time for many reasons. For some people, worries or anger could drive it. Many others naturally have a more nervous feeling or are likely to think over and over again. But even if you are born to be negative, that can be changed."Yes, it's hard to 'let go'," Leger said. But people can develop that skill through practice, in which you train the mind to pay attention to the present, rather than worries about the past."Paying attention to the present, especially on things you are grateful for, has been shown to have several advantages, "Leger said.1．What does the study result show us?'A．1, 155 people say they have physical health problems.B．During 24 hours, people never change their feelingsC．Only 17% of the people have no physical health problems.D．Only 20% don’t feel quite good about their physical strength.2．The underlined expression "that skill" in Paragraph 5 refers to _______.A．asking "what if”B．letting it goC．caring about the past D．thinking over and over3．The purpose of the passage is to _______.A．introduce different kinds of negative feelings.B．help people know about the national health studyC．teach readers the ways to let the negative feelings goD．ask people not to think over too much about the daily troubles4．Which part of the magazine is the passage most probably from ?A．Technology Part B．Advertisement Part.C．Health Study Part D．Chemical Research Part.D16、Do you know why different animals or pests (昆虫) have their special colors? Colors in them seem to be used mainly to protect themselves.Some birds like eating locusts (蝗虫), but birds cannot easily catch them. Why? It is because locusts change their colors together with the change of the colors of____When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color as crops have. Some other pests with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.If you study the animal life, you’ll find the main use of coloring is to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters (猎人).

I have never seen her angry at anything and never heard her say a harsh (苛刻) word to anyone or about anyone.Happy and her husband Ben, 70, have a huge garden. They spent many happy hours together working on it. Most of the neighbors watched interestingly as Ben doubled the size of their garden. As the cost of food climbed faster than Ben’s beans, we all wished we also had such a large garden. As the rest of us spent our dollars at the market, Happy could beseen picking beans in her back yard.Last month, Happy and Ben invited most of the neighborhood over for an “all-day food fes t”. We were told to bring gloves and arrive very early in the morning. We didn’t know what was about to take place.By 9:00 am, there were nine of us in the garden picking tomatoes, beans, okra, and squash. By 10:00 am, there was lots of laughter. We share d a lot of stories. By five o’clock, everyone was a little drunk from the wine and beer. After dinner, we played games. As we were leaving, Happy and Ben handed each of us a shopping bag filled with the bounty（收成）of the day, already packaged and frozen. What a delightful gift!Well, the point wasn’t so much about the food. The true gift was a day of friends enjoying one another’s company. None of it would have happened if it had been for Happy and Ben’s garden. Now they have a blog about gardening in case w e decided to plant a garden.

B．It was wonderful.C．It was not as good as he thought. D．It was too terrible.C15、What will you do if you are in trouble on a lonely island? Surely you need to find a way to get in touch with the outside world. Your best chance of doing this is to attract the attention of a passing plane.Body languagePilots(飞行员) from different countries understand body languages if they have the correct training. When you put your arms up and down in a straight line, it means, “yes”. When you point down and swing (摇摆) your arm from side t o side, it means “no”. If you want the pilot to know that it’s safe to land, push your hands out in front of you andbend(弯下) your knees. If you want to say that it’s not safe to land, put your arms up in the air and move them to oneside.Start a fireThe smoke from a fire can be seen from far away, so it's a good way to attract attention. If the weather is dry, it isn’t hard to start a fire. Remember, however, that fires can be very dangerous if they lose control. Never light a tire unless you’re sure that it can’t spread. If the ground is dark, light smoke can be seen more easily. Green grass and leaves produce light smoke.Ground- to- air marksIt’s a good idea to make some marks, too. Use large pieces of wood to make the marks. If you can’t find any wo od, use earth. Some useful marks are:F :“I need food and water”II:“I need medicine.”I:“I am badly hurt.”X:“I can’t move from here”So next time, if you meet this problem and can’t get away from the island, try the advice above.1．Which of the following means “It’s not safe to land”?A．A B．B C．C D．D2．If you are hungry and thirsty, you should draw_________ on the ground.A．F B．II C．I D．X3．From the passage, we can learn that ___________.A．Putting up and down your arms in a straight line means “No”B．Y ou should start a fire when you are sure it will spreadC．It’s a good idea to use flowers and grass to make marks on the groundD．Y our body language, smoke and ground marks are helpful to save you out4．The passage is mainly about _______.A．ways of living on a lonely islandB．ways of asking for help on a lonely islandC．body languages on an islandD．the importance of making marks on an islandD16、Long long ago, an elephant and a monkey lived in the same forest. They were good friends, but both of them were very proud. The elephant thought of himself strong, and the monkey felt himself quick.One day they went to ask the old bird, “Can you tell us which one of us is more important?” The old bird didn't give them the answer at once. However, he asked them to get some bananas on the other side of the river and bring them to him.So the elephant and the monkey went to the river, but the water ran so fast that the monkey was afraid.“Get on my back, Monkey,” said the elephant, “I shall take you there. I'm big and strong, and I can swim across the river.”Soon they got to the other side. The elephant tried to reach the bananas, but they were too high. “Wait a minute, please.I can climb,” said the monkey. He quickly ran up the tree and gave the bananas to th e elephant.Then they came back happily to the old bird and showed him the bananas. “Now, you see, the elephant is strong,” said the old bird with a smile, “but he couldn't get the bananas; the monkey is quick, but he couldn't, either. Only you two could do the work well when you helped each other.”1．Both the elephant and the monkey are ______ in the story.A．quick B．proud C．strong2．According to the story, ______ is more important.A．the monkey B．the elephant C．neither3．Picture ______ shows the right position of the banana tree.A．B．C．4．They should ______ to get the bananas.A．first swim across the river and then come backB．first climb up the tree and then swim across the riverC．first swim across the river and then climb up the tree5．The best title for the story is “______”.A．Teamwork is important B．An elephant and a monkey C．Strong or quickE17、I grew up in New Hampshire, a small town in South Canada, where in my father’s words for the seasons were “Spring, Summer, Fairtime and Winter!”At that time, a week-long fair was held in the town every autumn. Thousands of people from other towns came to sell and buy things. It was the busiest time of the year.When “Fairtime” came, my grandma became the busiest person of the fami ly. Grandma was a kind old lady. She was good at cooking. All her relatives liked the food she cooked. During “Fair time”, they would come to live in her house and have meals there. Grandma was always happy to look after them.Year after year, many people moved to big cities. There was no longer “Fairtime”. Grandma became very old and was gradually going blind. My parents and I moved to live with Grandma. We did our best to make her life comfortable.I was at high school then. What I often did at home was to help Grandma with the daily newspaper’s crossword puzzle. However, she didn’t look happy. She often sat in her room for hours, without saying a word.To attract（吸引）people to move back, the Town Hall decided to reopen the fair. One day, when I came back from school, I saw Grandma wearing her glasses, washing the dishes in the kitchen. With a big smile on her face, she looked much younger. She told me that her two nieces(侄女) would come. “They said the food I cooked was very delicious and they wanted to s tay in my house again,” Grandma said happily. “They will stay here for one week and we can have a big party. That must be the busiest week I’ve had in years!”I suddenly realized that Grandma didn’t want to be looked after. She wanted to be “useful” and he lpful.根据短文内容，选择最佳答案。
