AOne day, a little monkey and a little fox went out to play. They sawan apple tree on the other side of the river. There were many big and red apples on it. But there was no bridge over the river. The monkey thought hard and had an idea. They pulled down a tree and put it over the river as a bridge.The monkey said, “My old friend, you go there first.” But after the fox went to the other side, he kicked(踢) the tree into the river and ran to the apple tree. “How can I get there without the tree?” cried the monkey. The fox laughed and said, “You just stand there and watch me eating the apples.” The monkey was very angry.Suddenly it began to rain. The water level(水位) in the river rose and the tree flew away with the water.“You can eat all the apples. But you can’t come back,” shouted the monkey.The fox stopped eating and looked at the monkey sadly.1.The little monkey and the little fox wanted to on the other side of the river.A.build a bridgeB. eat the applesC. pull down a treeD. play games2.The fox kicked the tree into the river because he wanted to .A.eat all the apples by himselfB.share the apples with the monkeyB.get the apples first D. play a joke on the monkey3.The fox could not come back because .A.the monkey took away the treeB. the tree flew awayC. it began to rainD. he was angry with the monkey4.The fox was sad because .A.the monkey was laughingB. he couldn’t reachthe applesC . he couldn’t go back D. the monkeywent home first5.The story tells us that .A.the fox was strongB. the monkeyshould go firstB.the fox was clever than the monkey D. one shouldn’t care abouthimselfBEarthquake may happen anywhere on the earth. When some plates(板块) of the earth move suddenly, an earthquake happens. Many earthquakes begin under the sea. They often happen near the mountains, too.During an earthquake, the shakings make rocks rise suddenly and even crack(断裂) open. Houses fall, people are killed and hurt, and sometime the whole villages or cities are destroyed.Can we do something to keep ourselves safe from earthquakes? Scientists have studied earthquakes and made maps that show the “earthquakebelts”. In areas in these belts, it’s possible for earthquakes to happen. In these areas we should build strong houses to fight against (对抗) earthquakes.In the future, scientists will be able to tell when and where an earthquake will be before they happen. They can also tell people what to do and how to do it.6.The reason for an earthquake is .A.that some plates move suddenlyB. that the sea is too deepC. rocks’cracking openD. that the mountains are too high7. A lot of earthquakes often happen .A. in the areaB. next to mountainsC. at nightD. in the morning8. A map showing the earthquake belts will tell people .A. what kind of houses to buildB. what kind of houses can stay up in an earthquakeC. where earthquakes may happenD. when earthquakes may happen9. Which of the following is TRUE according to the passage?A. During an earthquake few people are killed or hurt.B. The scientist can tell when and where an earthquake is now.C. We should build strong houses to fight against earthquakes.D. Earthquakes all happen near the mountains.10. In the future, we’ll be no longer so afraid of earthquakes .A. with the help of scientists’ exact prediction(预测)B. because of a map showing the “earthquake belts”C. because we can guess the date and place of earthquakesD. because no earthquakes will happen around usCHow can you buy a meal for lunch without any money in your pocket?Students in Class 9, Grade 8 at Mountain and Lake Middle School in Chengdu, Sichuan, have their ways. They give out flyers(传单), draw portraits(人物素描) and work as waiters.The class, working in eight groups, finished the activity, Experiencing Life for Seven Hours, on March 18. “ I found students waste their food in the canteen,” the class teacher, Deng Guirong, told Teens. “ So I held this activity to help them understand how hard it is make money.”Jiang Yao, 15 and his group members stood in the streets giving out flyers for about two hours and got the money for their lunch. Then they worked as waiters in a pizza restaurant--cleaning the floor and toilets and getting food for guests. “We were busy all along, so we were terribly exhausted after the day’s hard work,” said Jiang. “We each got a pizza as a prize, which tasted much better than one I ate with my parents before.”When Xie Ni’s group didn’t make any money in three hours, the members became nervous about their lunch. The 14--year-- old girl came up with the idea of drawing portraits to sell, “ I sold four portraits and one tourist even paid us 100yuan for his portrait.” said Xie.Xie realized that life is really hard. “We have to work hard to get the money to pay foe even a simple meal.” Xie said, “ We must value the happy life today.”On top of making money, each group was asked to do at least five good deeds during the seven hours. Students helped the old cross the road, gave directions to tourists and turned in a lost bus card.11.From the teacher’s words, we can see that the students .ually waste food on their daily lifeB.realize life is really not easyC.know it’s hard to make moneyD.have their own ways to get food without money12.The underlined word “exhausted” in Paragraph 3means .A.HappyB. crazyC. tiredD. boring13.In order to make money, the students have done allexcept .A.help the old cross the roadB. give outflyersC. draw portraitsD. work as waiters14.
