The plane took off from an airport（飛機場）in Switzerland. It slowly rose above the fields and into the sky. “There has never been an airplane of that kind that could fly—never an airplane so big, so light, using so little energy.” said Bertrand Piccard, a leader of the project. During the 90minute flight （飛行）, the plane did several turns. It climbed nearly 1. 6 km above the countryside. Engineers（工程師） plan to test a night flight（飛行）before July. Then they will use the results（結(jié)果）of the tests to build a second plane. They plan to travel around the world in that plane in 2012. “We want to fly it day and night with no fuel（燃料）,” Piccard said. Piccard and pilot （飛行員）Andre Borschberg will take the plane around the world. They will make a few stops to change places and rest after a long time in the airand to show off their airplane. The plane will fly at 70 km per hour on average（平均）. That is faster than a bike and slower than a car. The pilots will keep the plane in the air for up to five days at a time. （1）The passage is probably taken from .A.a postcard（明信片）B.a newspaperC.a ic bookD.an advertisement（2）The solarpowered plane .A.is big and heavyB.uses much energyC.passed the first flight testD.will have a night flight after July（3）How long will it take the solarpowered plane to travel 140 km?A.About a day and a night.B.About 5 days.C.About 2 hours.D.About 90 minutes.（4）Which of the following is NOT mentioned（提到） in the passage?A.During the 90 minute flight, the solarpowered plane reached a height of 1. 6 km.B.The solarpowered plane is slower than a car and faster than a bike.C.Maybe the solarpowered plane will fly with no fuel.D.It took a long time to build the solarpowered plane.13．閱讀理解 Do you know the whales in the sea? There are many relatives（親屬） in the whale family and they always live together with whales. Few people know dolphins（海豚） are part of the whale family. Dolphins are not fish. They are mammals（哺乳動物）. They breathe air, and they have babies and feed them with milk. Dolphins are famous for their wonderful shows. They can jump high out of the water and show turns in the air. These jumps give the dolphins time to breathe. Porpoises（鼠海豚） are also in the whale family and are quite like dolphins. But they are different in the size and shape of the mouth. The dolphin39。s mouth is long and thin, but the porpoise39。s is short and thick. Dolphins are also more talkative than porpoises. Dolphins make sounds to talk with each other under water. But porpoises do not do this. Both of them are smart and friendly to humans. Not all the members of the whale family are friendly. Big whales are much easier to be angry than smaller dolphins or porpoises. An angry whale can be dangerous. Perhaps this helped to create the story of Moby Dick that sank （使下沉） a ship and made all the people on it die in the sea.（1）According to the passage, the porpoise . A.is a kind of mouseB.is friendly to humansC.is much bigger than the dolphinD.has a longer nose than the dolphin（2）What can we learn from the passage? A.Dolphins and porpoises have great differences in their habits.B.Whale families often like swimming and living in groups.C.Porpoises make sounds to municate with one another under water.D.Dolphins jump high out of the water to have fun.（3）The underlined part Moby Dick in the last paragraph is probably . A.a shipB.a dolphinC.a porpoiseD.a whale（4）Which is the best title for the passage? A.Food that Whales EatB.Whales39。 Eating HabitsC.Members of the Whale FamilyD.Differences Between Dolphins and Porpoises14．閱讀理解 When I was in primary school, I got into a big argument（爭吵）with a boy in my class. I forgot what the argument was about, but I will never forget the lesson I learned that day. I thought that I was right and he was wrong – and he thought that I was wrong and he was right. The teacher decided to teach us a very important lesson. She brought us to the front of the class and asked him to stand on one side of her desk and me on the other. In the middle of her desk was a large, round ball. I could clearly see that it was black. She asked the boy what color the ball was. White, he answered. I couldn39。t believe he said the ball was white, when it was obviously（明顯地）black! Another argument started between us, this time about the color of the ball. The teacher told us to change places and then asked me what color the ball was. I answered: White. It was a ball with two differently colored sides, and from his side it was white. Only from my side it was black. Sometimes we need to look at problems from the other person39。s view in order to（為了）truly understand his or her perspective（觀點）.（1）What happened to the writer in the beginning?
