It is 4039 meters above sea level(平面).The team built a station there to study the changes of the weather, to get ice samples(标本) from 150 meters to 200 meters below, and to do other studies. So far, the team has got nearly 100-meter-long ice samples from a place about 300 meters under the icecap peak.It is the first time that people have been able to get samples from the icecap peak in Antarctic and it is very important for people to study the weather changes and environmental changes in this area.The Chinese scientists also built a weather study system at the peak. The system can send out information about temperature, how strong the wind is, and many other things about the weather.The Antarctic icecap makes up (组成) 70% of the earth’s fresh water(淡水). By studying Dome A, scientists can get the lowest temperature of the earth and other information about the world’s weather changes. We can’t get this information from other places on the earth because Dome A is the best place for this kind of studies. So it is very important to land on the peak of Dome A.28. According the passage, which of the following sentences is CORRECT?A. The Chinese team was the first to land on the Antarctic.B. The team built a station there to change the world’s weather.C. Dome A is the best place for scientists to study the world’s weather changes.D. The Chinese team isn’t the first to get ice samples from the ice cap beak in Antarctic.29.

Please!” the tiger called. “Please, let me out.” “No,” said the good man. “If I do, you will eat me.” “I will not eat you,” the tiger said. “Please let me out.”The good man believed the tiger. He opened the door of the cage. The tiger jumped out. “How silly you are,” the tiger laughed. “Now I am going to eat you.” “Wait!” the man cried. “You ought not to eat me. Let us ask others what they think.” “You may ask three others. ” the tiger said.The good man asked a tree. The tree said, “I give shade (树荫). And yet I am cut down. Let the tiger eat you.”Next, the good man asked a bird. The bird said, “I hurt no one. Yet people hunt and kill me. Let the tiger eat you.”The last one that the good man asked was a road. The road said, “I don’t care if the tiger eats you. People could not get along too well without me. Yet all day and all night people step on me without even a ‘thank you’.”The tiger was ready to eat the good man. Just then a dog came by. “What is happening?” asked the dog. The man told the dog th e whole story.“I don’t understand,” said the dog. “The tiger wants to eat you because you put him in a cage?”“No, no,” said the man. “Some other men put him in a cage.”“Oh,” the dog said. “He is going to eat you because you do not have a cage.”“Silly dog!” the tiger cried. “Don’t you understand? I was in the cage. This man let me out.”“Oh, I see,” the dog said. “When the man was in the cage, you let him out.”“I was in the cage!” the tiger cried. “In this way!” with that, he jumped back into the cage.At once, the dog closed the door of the cage. “Oh,” the dog laughed. “At last I understand!”The good man and the dog walked off. The tiger looked sad in the cage. If he waited long enough, perhaps another good man would come by.32.

Do you want to eat every delicious food in the world? Then do you watch the popular program?“A Bite of China(舌尖上的中国)” is a documentary on Chinese delicious food which has been broadcasted by Chinese central television. Is there any holiday that isn't celebrated with a special festival food? Here are several traditional Chinese foods:Eggs hold a special meaning in many cultures, and China is no exception(例外). The Chinese believe eggs mean producing something new. After a baby is born, parents may hold a "red egg and ginger party," where they pass out eggs to announce the birth. In some areas of China the number of eggs represents the sex of the child, for example, an even number(1,3,5,---) for a girl, and an odd number(2,4,6---) if a boy has been born.Noodles are a symbol of longlife in Chinese culture. They are as much a part of a Chinese birthday celebration as a birthday cake with lit candles is in many countries. Since noodles represent long life, it is considered very unlucky to cut it off.Although westerners sometimes may be very sorry to see fish lying on a plate, in China a whole fish is a symbol of richness. In fact, at a party it is traditional to serve the whole fish last, pointed toward the valued guest. Fish also has a special meaning because the Chinese word for fish, yu, sounds like the word for richness or plenty, and it is believed that eating fish will help your wishes come true in the year to come.A very popular dish during the Dragon Boat Festival is Zongzi. This tasty dish is made of rice dumplings with meat, peanut or other delicious food in bamboo leaves. The tradition of Zongzi is meant to remind us of a great man, Qu Yuan. The 50-minute program tries to bring something new by presenting more cultural elements(元素),such as eating habits and the quality of eating.1．A bite of China is _______________.A．a book B．a documentaryC．a guide book D．a newspaper2．How many kinds of traditional food are mentioned in the passage?A．two B．threeC．four D．five3．A girl has been born in Mr. Li’s home. How many red eggs may he pass out to his friends according to Chinese tradition?A．two eggs B．noneC．three eggs D．six eggs4．Which of the following is RIGHT according to the passage?A．We can cut birthday noodles off in China if we think they are too long.B．It is impolite to server a whole fish last at a party in China.C．The program lasts for one hour.D．There are many kinds of Zongzi during the Dragon Boat Festival.5．What does the writer mean in the last paragraph?A．The writer thinks the program is too long.B．The writer thinks the program has more meanings inside than the story itself.C．The writer thinks everyone can have a good eating habit after watching the program.D．The writer thinks the program has brought many kinds of delicious food to us.C15、When you cough or sneeze, please turn your head away from others and cover your mouth with the full part of your hand. And then, you should say, “Excuse me.” This is a rule I set for my studentsIt is so simple, but many kinds have never been told to do this. In fact, I notice adults cough and sneeze in public without putting a hand over the mouth. I hate traveling by subway in New York during cold and flu season, because it is certain that someone is going to stand right behind me and cough or sneeze on my neck.One important thing I point out to the kids is that after they sneeze or cough on their hand, they should wash their hands as soon as possible. Or they will be passing those germs (病菌) along to everything and everyone they touch.In order to help the kids remember this rule, I tell them about an old story. It says that when you sneeze, evil spirits (幽灵) jump into your b ody. If you don’t cover your mouth, the spirits will enter, but if you cover your mouth, you will keep them out, We say “God bless you” (上帝保佑你) when someone sneezes, and in Germany you should say “Gesundheit” (祝你健康). That means “Good health to you.” Both expressions are said just in case you didn’t cover your mouth in time and the spirits were able to enter your body. The kids love finding out the origins (起源) of these expressions and it encourages them to put the advice to use more often.1．What does the u nderline word ‘this” mean?A．Don’t cough or sneeze in front of people.B．Don’t stand beside someone who coughs or sneezes.C．Cover your mouth when coughing or sneezing and say sorry.D．Many people cough or sneeze on the underground train.2．After coughing or sneezing on their hand, students are advised to ______.A．say “God bless you” B．wash their hands as soon as possibleC．go to see a doctor as soon as possible D．go home and have a good rest3．Why does the writer hate traveling by subway in New York during cold and flu season?A．Because many people cough or sneeze on the underground train.B．Because it’s too crowded.C．Because people like coughing or sneezing there.D．Because there are too many germs.4．According to the article, the writer would like the kids ______.A．to be polite to adults B．to be in better healthC．to do well in exams D．to have good manners5．From the passage, we can infer (推断) that the writer must be ______.A．a reporter B．a doctor C．a teacher D．a studentD16、News ReviewLearn to swim. Do you want to study in Tsinghua(清华) University? If your answer is yes, you need to be able to swim or get prepared to learn to swim from now on. Recently, the university has made a new rule that students must pass the50-meter swimming test to finish school. This rule has been brought into a broad discussion. Some agree with it because it can help students do more sports, but others disagree. They believe that it doesn’t respec t their personal wishes. It shouldn’t be a must for graduation. What’s your opinion?______________________“Thomas Edison was an great inventor in the US. When he was seven, her mother caught a serious illness so she had to receive an operation（手术）in time. However, the room was too dark. So Edison brought a mirror and an oil lamp to light the room. How smart he was.” This story comes from the Chinese textbook forGrade-two students in the primary school. But recently, many people believe it was not true because the first operation about that illness in the world took place in 1886. Edison reached seven years old in 1854. Some people wonder why the story appears in the textbook. Maybe that’s because the editor(编辑) cares too much about the educational meaning without checking whether it was true or not.Paper books never disappear With the development of E-books, many people prefer to read on the Internet. Some experts worry that paper books may die down as time goes by. However, a recent study has shown a rising enthusiasm of paper books all over the world, especially among young people of 16 to 24. Just in last month, 7% more paper books have been sold in the UK and E-book sale has fallen in a row by 4% in total over the month. Also, a survey made by Voxburner says that 60% of 16-to-24-year-olds prefer paper books. The most popular reasons given were, “ I love the feeling of holding the books and the smell of the paper, and I won’t end up with headache and sore eyes.1．According to the first paragraph, students in Tsinghua University must ____________ to finish school.A．do some sports B．pass a swimming test C．learn to discuss D．respect each other2．The blank in the second paragraph should be filled in “ _____________.”A．Thomas Edison’s childhood B．Some good stories in the textbookC．Textbooks are not true D．Educational meaning in Edison’s story3．The Chinese meaning of the underlined word “enthusiasm” in this passage is “________”.A．热情B．厌恶C．危机D．成本4．To explain why paper books never disappear, the writer does all the following things EXCEPT___________.A．list some numbers B．give us some reasonsC．show a survey result D．tell a story of his ownE17、A famous study was done in a school by a professor from a university. At the start of the school year, the teachers were given the names of five children. They were told that these five were the most excellent students in the class. But the fact was that these students were only average，and they were not the best students at all. Well, guess what? At the end of the year, all the five average students scored among the highest in the class.What made these average students change so much to become top students？The only difference was the change in their teachers’ attitude. Because the te achers believed that these five kids were the top students，they expected more from them. And so these five average students began to believe and expect more from themselves. So they worked harder to do as well as they could.Do you know why? If you expect the best from people, they’ll usually want to give you their best. A great leader said, “Treat a person just how he appears to be on the outside, and you’ll make him even worse. But treat a person like he’salready a success，and you’ll help make him the best he can be.”Like the true story of 7-year-old Johnny, his teacher got so angry with him that one day she said，“Johnny，you’re the naughtiest boy in this class. I’m sure you’ll never change.” The next year Johnny had a new teacher. And on the first day of class，she met with Johnny after school and said，“Johnny, I’ve heard a lot about you! But do you know that I don’t believe a word of it.” And every day after that, this new teacher treated Johnny as if he was one of the smartest students even when Johnny did naughty things. Later on, Johnny became a school leader. Because that’s the power of our belief and attitude toward children.1．The professor started his research by _______.A．teaching the five children himselfB．asking the five children to find a new teacherC．telling the five students to work harder than ever beforeD．telling the teacher the five students were the best in the class2．The five average students became top students mainly because of ________.A．the professor’s study B．the teachers’h ard workC．the change in the teachers D．the change in the teachers’ attitude3．What does the passage mainly tell us？A．Attitude and belief can change a person.B．Only teachers can make you a top student.C．A professor’s study can help you score highest.D．If you want to get more，you should have new teachers.F18、Advertising means to draw people’s attention to something.
