Questions 16-20 are based on the following passage:
Lazy? Shy? Live in a cave? Those might not be positive attributes for the average human, but they sure are good for animals trying to survive in a changing environment. According to a new study, beasts that hibernate (冬眠) or crawl into holes are less likely to be listed as endangered than those that don't.
Following up a previous study on extinct animals, which showed that species exhibiting "sleep or hide" (SLOH) behaviors did better than others, the researchers wanted to see if the same was true of modern creatures like moles and bears. To find out if our more timid animals have a leg up in the survival game, researchers made a master list of 443 sleep-or-hide mammals.
With their list in hand, the team compared their 443 to the "red list" of endangered species published by the International Union for Conservation of Nature. As suspected, a sleepy or hiding animal was less likely to be on the red list than a regular animal, and a red-list animal was also less likely to be a SLOH-er.
This makes a lot of sense, as animals that hide away in a cave or a tree hole are protected by their physical shelters from a variable environment outside, while hibernators enjoy a flexible metabolism (新陈代谢) that can help them adapt to a changing climate.
16. On the list of extinct animals studied, there were _____________.
A. fewer SLOH-ers than regular animals
B. more SLOH-ers than expected
C. as many SLOH-ers as regular animals
D. hardly any SLOH-ers

C. a fight
D. a chance
18. The study of modem creatures ___________.
A. is unrelated to the study of extinct animals
B. finds evidence missing in the study of extinct animals
C. has findings similar to those of the study of extinct animals
D. reveals a different pattern from the study of extinct animals
19. According to the passage, red-list animals are more likely to ____________.
A. be lazy
B. be timid
C. live long
D. sleep less
20. In the last paragraph the author ____________.
A. compares the behaviors of sleepers and hiders
B. offers an explanation for the survival of sleepers and hiders
C. analyzes how a changing environment affects SLOH-ers
D. emphasizes what can be learned from SLOH-ers [NextPage]
Questions 21-25 are based on the following passage:
In computing, passwords are commonly used to limit access to official users. Yet the widespread use of passwords has serious drawbacks. Office workers now have to remember an average of twelve system passwords. In theory they should use different passwords for each site, but in reality these would be impossible to remember, so many people use the same password for all.
An additional problem is that the majority use simple words such as "hello", or names of family members, instead of more secure combinations of numbers and letters, such as 6ANV76Y. This permits computer hackers to download dictionaries and quickly find the word that allows them access.
When system users forget their passwords there is extra expense in supplying new ones, while if people are forced to change passwords frequently they often write them down, making systems even less secure. Therefore, it is clear that the idea of passwords, which have been used as security devices for thousands of years, may need rethinking.
One possible alternative has been developed by the American firm Real User, and is called "passfaces". In order to access the system a worker has to select a series of photographs of faces from a randomly (随机地) generated sequence. If the pictures are selected in the correct order, access is granted. This concept depends on the human ability to recognize and remember a huge number of different faces, and the advantage is that such a sequence cannot be told to anyone or written down, so is more secure. It is claimed that the picture sequence, which used photographs of university students, is easier to remember than passwords, and it has now been adopted for the United States Senate.
21. What is the disadvantage of passwords as mentioned in Paragraph 1 ?
A. They do not ensure security.
B. They are difficult to remember.
C. They have to be changed frequently.
D. They limit computer accessibility.
22. One can make a password safer by _____________.
A. inserting pictures between numbers
B. avoiding the use of letters altogether
C. setting up a firewall against computer hackers
D. using complicated combinations of numbers and letters
23. "Passfaces" is a method to get access to a system through ___________.
A. remembering a large number of faces
B. selecting photographs of faces one likes
C. recognizing a sequence of face pictures
D. showing one's face in front of the computer
24. One advantage of "Passfaces" over a password is that ____________.
A. it is easier to remember
B. it is more complicated
C. it takes less time to log in
D. it allows one to write less
25. What does the author think of the password?
A. R is an old system that needs improvement.
B. It provides as much security as before.
C. R should be abandoned by computer users.
D. It has developed to an advanced stage. [NextPage]

Part Three Cloze
Directions:
There are ten blanks in the following passage. For each numbered blank, there are four choices marked A, B, C and D. Choose the best one and mark your answer on the ANSWER SHEET with a single line through the center.
Fueled by weather, wind, and dry undergrowth, uncontrolled wildfires can burn acres of land—and consume everything in their way—in mere minutes.
31 , more than 100,000 wildfires clear 4 million to 5 million acres of land in the U.S. every year. A wildfire moves at speeds of up to 23 kilometers an hour, consuming everything—trees, bushes, homes, even humans—in its 32.
There are three conditions that need to be 33 in order for a wildfire to burn: fuel, oxygen, and a heat source. Fuel is any material 34 a fire that will burn quickly and easily, including trees, grasses, bushes, even homes. Air supplies the oxygen a fire 35 to burn. Heat sources help spark the wildfire and bring fuel to 36 hot enough to start burning. Lightning, burning campfires or cigarettes, hot winds, and even the sun can all provide 37 heat to spark a wildfire.
38 often harmful and destructive to humans, naturally occurring wildfires play a positive role in nature. They 39 nutrients to the soil by burning dead or decaying matter. They remove diseased plants and harmful insects from a forest ecosystem (生态系统). And by burning 40 thick trees and bushes, wildfires allow sunlight to reach the forest floor, enabling a new generation of young plants to grow.
