After the Experiment B B My first day of school was very interesting and couldnt be easily forgotten. I went to my science class in the morning and found a seat in the back. I waited there for 15 minutes before the bell rang. The science teacher told us about some class rules. No one talked to me and I didnt talk to anyone else. I was one of those very shy girls. After the science class, I had an English class. I thought it would be boring but later I found it very funny. When the classes of the morning ended I went to lunch. I sat outside the dining room with no one to talk to and no food because I was too nervous to join the lunch line. I kept looking around hoping to see someone I knew but I never saw anyone. Lunch ended and I went to have my art class. I was the first one there and not even my teacher was there yet. So I sat at my desk and started drawing some pictures. I didnt notice the rest of the class walking in or the girl that was standing behind me till I was surprised by the voice, “So what are you drawing?“ It was a girl who had really long hair. She ended up being my best friend and one of the kindest and liveliest girls I know. In the next class meeting, the teacher asked us to talk about the past holiday. I was glad to make some new friends in the class. The first day of high school was hard for me but I got through it. 61. What do we know about the writers science class? A.

C C If youre ever apart from your children, a new study says just talking on the phone will help just as much as a hug(拥抱). If youre a parent who spends long hours on the job, you probably feel sorry for spending so much time away from your kids. But the results of a new study show that a mothers voice alone can be just as comforting to an anxious child as physical contact(接触). In an experiment, researchers from the University of Wisconsin Madison asked a group of girls between the ages of 7 and 12 to solve math problems in front of judgesa stressful situation for anyone. Before the girls were set to give their answers, the researchers measured their levels of two hormones(荷尔蒙): cortisol, which goes up during stressful periods, and oxytocin, the “love“ hormone, which goes down at the same time. After the girls finished the problems, some of them got to meet up with their mothers right away. The moms came in and hugged the girls. Another group of the girls didnt see their mothers, but received phone calls from them, in which their mothers told them how well theyd done. The final group had no contact with their mothers, but instead watched an animal movie, March of the Penguins. Finally, the girls hormone levels were measured again. Although the movie was interesting, it did nothing to reduce the childrens anxietybut, surprisingly, both the physical contact and phone calls from their mothers had the same effect on reducing the girls stress levels. So, no matter how old you are, if youre feeling stressed about something in your life, a phone call to Mom might be just the key to help you feel better. 66. If a girl is under stress, . A. she cant solve math problems B. she will have high levels of hormone 8 C. oxytocin will remain at a high level D. cortisol will go up with oxytocin down 67. Which of the following is the right order in which the study was carried out? a. The girls levels of hormones were measured again. b. The girls solved math problems. c. The girls levels of hormones were measured. d. The girls were divided into three groups. A. b-c-d-aB. d-b-c-aC. c-b-d-aD. d-c-b-a 68. From the passage, we can infer that . A. it is easy for girls to solve math problems B. the girls who had watched the movie remained anxious C. mothers should hug their kids as often as possible D. older girls have higher cortisol than younger ones 69. Whats the main idea of the passage? A. A mothers voice can comfort her anxious kids. B. Mothers should often hug their kids. C. Mothers should spend enough time caring about their kids. D. Scientists discovered why kids become stressed when having tests. D D A fish that lives in America can live out of water for months at a time, similar to how animals got used to land millions of years ago, a new study shows. The Mangrove Rivulets, a kind of little fish, lives in small pools of water. When their living place dries up, they live on the land, said Scott Taylor, a researcher in Florida. The fish can grow as large as three inches. They group together and breathe air through their skin before they can find water again. The new scientific discovery came during a trip. “We were travelling for fun. And one day I kicked over a log (圆木) and the fish came out.” Taylor told reporters by telephone. He said he would make his study on the fish known to the public in an American magazine early next year. In lab tests, Taylor said he found the fish can live up to 66 days out of water without eating. Some other fish can live out of water for a short period of time. The walking catfish found in Southeast Asia can stay on land for hours at a time, 9 while lungfish(肺鱼) found in Australia, Africa and South America can live out of water, but only in a not active(活跃的) way. But no other known fish can be out of water as long as the Mangrove Rivulets and keep active, according to Patricia Wright, a biologist at a Canadian University. More studies of the fish may tell how animals changed over time. “These animals live in conditions similar to those millions of years ago, when animals began to move from water onto land.” Wright said. 70. The Mangrove Rivulets is a type of fish that . A. lives on land in Africa B. can stay alive for months out of water C. prefers living in dry places D. is the longest living fish on earth 71. Who will write a report on Mangrove Rivulets? A. Scott Taylor.B. Some reporters. C. Patricia Wright.D. Scientists from Europe. 72. According to the passage, lungfish can . A. breathe through its skinB. be found in Asia C. keep alive out of waterD. keep alive and walk on land 73. Which one of the sentences below is not true? A. The Mangrove Rivulets fish can live out of water as long as other animals if it has something to eat. B. Millions of years ago, animals began to live onto land from water. C. Lungfish found in Australia, Africa and South America can live out of water in a not active way. D. The walking catfish found in Southeast Asia can stay on land for hours at a time. 74. What can we say about the discovery of Mangrove Rivulets? A. It was made by Scott Taylor, a researcher in New York. B. It was helped by an American magazine. C. It was helped by Patricia Wright. D. It was made by a researcher while travelling. 七、短文七、短文 7 7 选选 5(55(5 选选 5 5 等等) ) 10 Imagine a boy from a small village in East Africa. He has been looking after cows from a very early age. At twelve, he knows more about cows than most of us. 75. Has this boy ever had any education? Education is discovering about ourselves and about the people and things around us. All the people who care about usour parents, brothers, sisters, friendsare our teachers. 76. We start learning on the day we are born, not on the first day we go to school. Every day we have new experiences, like finding a birds nest(巢), discovering a new street in our neighborhood and making friends with someone we didnt like before. 77. Encouragement from the people around us makes it possible for us to discover things as much as possible. As we grow up, we begin to find out what we are able to do. We may be good at cooking, or singing or playing football. 78. Just thinking about cooking doesnt tell us if we are good at it. We learn so much just in our daily life. 79. Of course we can learn some things better at home than at school, like how to do the shopping, and how to help old or disabled people who cant do everything for themselves. At school, teachers help us to read and write. With their help, we begin to see things in different ways. A. To share new experiences with other people is even more fun. B. In fact, we learn something from everyone we meet. C. We find this out by doing these things. D. However, he has never been to school. E. So why is school important? 八、阅读与表达八、阅读与表达( (问答式问答式) ) Last month I got the chance to take part in an underwater research project in an area of the Gulf of Mexico called the Flower Gardens. A team of professional researchers were trying to learn more about the fish and other animals that live in this part of the sea. The Flower Gardens are a long way from the shore(海岸) and we spent three days on a boat. The team used a piece of underwater equipment to collect information. This underwater equipment is called a Remotely Operated Vehicle (ROV). The ROV could measure water depth and temperature and it also had a camera that sent live film back to the boat. The ROV was great fun. It was controlled by a computer on the boat, and I was allowed to operate it a few times. 11 However, the thing I enjoyed most was diving into the water. At first, I was quite frightenedmainly because I couldnt see land in any direction. But as soon as I jumped into the water, I wasnt afraid anymore. It was amazing to see the colourful fish swimming around and I could see all the way to the Flower Gardens,
