II. Reading comprehension Part A
Directions: Read the following passages, and choose the correct answers. (30 points)
Passage 1
Conservationists (资源保护者) may get a wrong number of the threatened animals such as elephants, say African and American researchers. The error takes place because of a weakness in the way they estimate animal number from the piles of dung (粪便) the creatures leave behind.
The mistake could lead researchers to think that there are twice as many elephants as there really are in some regions, according to Andrew Plumptre of the Wildlife Conservation Society (WCS) in New York. Biologist (生物学家) Katy Payne of Cornell University in Ithaca, New York, agrees. “We really need to know elephant number and the evidence (证据) that we have is quite indirect,” says Payne.
Counting elephants from planes is impossible in the vast rainforests of Central Africa, so researchers often estimate elephant number by counting dung piles in a given area. They also need to know the rate at which dung decays (腐化). Because it's quite difficult to decide these rates, however, researchers counting elephants in one region are likely to rely on standard decay rates set up elsewhere.
But researchers at the WCS have found that these decay rates differ from region to region depending on the weather and environment. Using the wrong number can mislead the census (统计), says Plumptre.
He and his colleague Anthony Chifu Nchanji studied decaying elephant dung in the forests of Banyang Wildlife Sanctuary (避难所) in southeast Cameroon. They found that the dung decayed between 55 and 65 percent more slowly than dung in the rainforests of neighboring Gabon. If researchers use decay rates from Gabon to count elephants in Cameroon, they would probably find more elephants than there are actually around.
This could mean estimates in Cameroon are at least twice as high as those got from decay rates calculated locally, says Plumtre. He says that similar problems may also exist in other animal census studies that rely on indirect evidence.
26. The word “threatened” (Line 1, Para. 1) could be best replaced by____.
A. endangered
B. frightened C. spoiled D. angered
27. Why do researchers count elephants in an area by counting dung piles?
;.
A. Because elephants are difficult to catch.
..
B. Because it is not possible to count elephants from a plane. C. Because it is impossible to follow the track of elephants.
D. Because they think dung piles are most reliable for counting elephants.
28. Piles of dung can't be relied upon when it comes to estimating elephants number because _____.
A. they are different in size
C. they are different in rate of decaying
B. they scatter all over the region D. they are difficult to be identified
29. Suppose the number of elephants got in Cameroon is 1000 by using the decay rates set up in Gabon, then
the actual number maybe about _______.
A. 500
B. 2000 C. 400 D. 2500
30. Which of the following is not a useful factor in estimating elephant number in one region?
A. Dung piles number. C. Climate and environment.
B. Rates of dung decaying. D. Wildlife sanctuary.
Passage 2
I was in a chat room, as most online romances happen. I had been on the Internet and chatting for almost three years. I was bored one afternoon, so I decided to go into a chat room. I had been in this particular room many times before, and met some very interesting people in it. While I was in there, I noticed two guys talking. One was married and had kids, and the other was asking questions like what it was like to be a father, etc. I was most interested in him, he sounded so sweet. So I decided to start chatting with him. We didn't get to chat long, because of the 6-hour time difference, but it was a wonderful chat. He was a few years older than me, but I figured age didn't matter if we had a good chat.
We got to talking about many things, mostly music though. Before he had to leave he gave me his e-mail address and I gave him my AOL (美国在线服务公司) Instant Messenger screen name. A few days later while I was online someone greeted me, and it was him. He told me who it was and we started chatting. Like most people, we had many things in common. We had similar views on life, etc.
After many conversations, I realized I was really starting to like this guy. I had promised myself before that it's just not right for people over the Internet to be “in love”, and that I'd never do such a thing. It just didn't seem right to me. Since, I thought, you never knew whom you are really talking to. Well, my opinions started to change, very quickly too.
Weeks later our relationship really started to get serious. I felt ashamed at first, because it was on the Internet, but I don't worry about it now. All I have to say is that I have never loved someone so much before.
31. We can safely say that _____________.
;.
A. both the guys were married
..
B. both the guys had children
C. one of the guys had children but the other hadn't any
D. one of the guys was married but the other had never had a girlfriend

33. From the first paragraph we know that the narrator and the guy _____________.
A. lived in the same city
B. lived very far away
C. both lived in the United States
D. often went together to the same room to have a talk
34. The word “it” in Paragraph 2 refers to ________________.

B. the narrator's screen name D. the guy
35. The narrator felt ashamed at first because ________________.

Passage 3
Nowadays it is understood that a diet which contains nothing harmful may yet result in serious disease if certain important elements are missing. These elements are called “vitamins (维生素).” Quite a number of such substances are known and they are given letters to identify (识别) them, A, B, C, D, and so on. Different diseases are associated with (与……有关) a lack of particular vitamins. Even a slight lack of Vitamin C, the vitamin most plentiful in fresh fruit and vegetables, for example, is thought to increase significantly our susceptibility (易感性) to colds and influenza (流感).
The vitamins necessary for a healthy body are normally supplied by a good mixed diet, including a variety of fruit and green vegetables. It is only when people try to live on a very restricted (限定) diet, say when trying to lose weight, that it is necessary to have a special supply to make up the missing vitamins.
Another example of the dangers of a restricted diet may be seen in the disease known as “beriberi” (脚气病), from which large numbers of Eastern peoples who lived mainly on rice used to suffer very much. In the early years of this century, a Dutch (荷兰的) scientist called Eijkman was trying to discover the cause of beriberi. At first he thought it was transmitted by a germ (细菌). He was working in a Japanese hospital,
