5 阅读理解。 A man went to a barbershop to have his hair and beard cut as always. He started to have a good conversation with the barber who attended him. They talked about so many things on various subjects. Suddenly, they touched the subject of God. The barber said," I don"t believe that God exists as you say so."" Why do you day that?" asked the client (顾客)." well, it"s so easy; you just have to go out in the street to realize that God does not exist.""Oh, tell me."" If God existed, would there be so many sick people? Would there be so many abandoned children? If God existed, there would be neither suffering nor pain. I can"t think of God who permits all of these things." The client stopped for a moment thinking but he didn"t want to respond so as to prevent an argument. The barber finished his job and the client went out of the shop. Just after he left the barbershop, he saw a man in the street with long hair and beard. Then the client again entered the barbershop and he said to the barber," Knowing what? Barbers do not exist." " How come they don"t exist?" asked the barber,"Well I am here and I am a barber.""No!" the client exclaimed,"They don"t exist because if they did there would be no people with long hair and beard like that man who walks in the street." "Ah, barbers do exist, what happens is that people do not come to me." "Exactly!" affirmed the client. "That"s the point. God does exist, what happens is that people don"t go to him for help.

9 阅读理解。　Our boat floated on, between walls of forest which were too thick to allow us a view of the land we were passing through, although we knew from the map that our river must from time to time be passing through chains of hills which crossed the jungle plains. Nowhere did we find a place where we could have landed: where the jungle did not actually spread down into the river, banks of soft mud prevented us going ashore. In any case, what would we have gained by landing? The country was full of snakes and other dangerous creatures and the jungle was so thick that one would be able to advance only slowly, cutting one"s way with knives the whole way. So we stayed in the boat, hoping that when we reached the sea, a friendly fisherman would pick us up and take us to civilization. 　　 We lived on fish, any fruit and nuts we could pick up out of the water. As we had no fire, we had to eat everything, including the fish, raw. I had never tasted raw fish before, and I must say I did not much enjoy the experience: perhaps sea-fish which don"t live in the mud are less tasteless. After eating my fish, I lay back and dreamed of such things as fried chicken and rice, and ice cream. In the never-ending heat of the jungle, ice cream was a particularly frequent dream.　　 As for water, there was a choice. We could drink the muddy river water, or die of thirst. We drank the water. Men who have just escaped what had appeared to certain death lose all worries about such small things as diseases caused by dirty water. In fact, none of us suffered from any illness as a result. One day we passed another village, but fortunately nobody saw us. We did not wish to risk being taken prisoners a second time: we might not be so lucky as to escape in a stolen boat again. 1. The only thing that they could see in the boat was _______. 　　 A. chains of hills 　　　　 B. high walls C. vast land 　　　　　　　 D. tall trees 　 2. They were prevented from landing because they could not _______. 　　 A. find the place marked on the map 　　　　 B. go through the thick forest 　　 C. go across the soft mud 　　　　　　　　　 D. see the plains 　 3. This passage is mainly about ______. 　　 A. the problem of landing 　　　　 B. a terrible experience 　　 C. walls of forest　　　　　　　　 D. the fishermen"s worries 　 4. Which of the following is NOT true according to the passage? 　　 A. The author and his partners were trapped during scientific exploration. 　　 B. They were floating on a small boat in the jungle without help. 　　 C. The dirty water they drank didn"t threaten their lives. 　　 D. They had no food or drinking water prepared.
