Script: The Internet is now playing an essential role in the interpersonal connection and communication. Letters, telephone calls, telexes, faxes, etc. are no longer the only ways to communicate.
Instead, one can have contact with others by e-mail, net chat, BBS, IRC, MAVEN, CU-SeeMe and so on with the help of the Internet. For example, during the period of SARS, students in Beijing had to be sent away from school. As a result, their school education was forced to be cut off. However, a new flavor helped solve the problem. Do you know how? Thanks to the Internet, a new system called "Education On-line" was being carried out. With their PCs at home, students cruised around their school websites
merely by inputting the IP addresses. Here, sufficient lectures, materials, exercises and homework are available on-line.
Part II Reading Comprehension ( 25 minutes )
Section A
Directions: In this section, there is a passage with several blanks. You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. You may not use any of the words in the bank more than once.

Section B
Directions: There are several passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B),
C) and D). You should decide on the best choice.
•Passage One
Questions 31 to 35 are based on the following passage.
In the 1950s, the pioneers of artificial intelligence (AI) predicted that, by the end of this century, computers would be conversing with us at work and robots would be performing our housework. But a
s useful as computers are, they're nowhere close to achieving anything remotely resembling these early aspirations for humanlike behavior. Never mind something as complex as conversation: the most powerful computers struggle to reliably recognize the shape of an object, the most elementary of tasks for a ten-month-old kid.
The problem, the scientists say, is that AI has been trying to separate the highest, most abstract levels of thought, like language and mathematics, and to duplicate them with logical, step-by-step programs. A new movement in AI, on the other hand, takes a closer look at the more roundabout way in which nature came up with intelligence. Many of these researchers study evolution and natural adaptation instead of formal logic and conventional computer programs. The results of these early efforts are as promising as they are peculiar, and the new nature-based AI movement is slowly but surely moving to the forefront of the field.
Imitating the brain's neural network is a huge step in the right direction, says computer scientist and biophysicist Michael Conrad, but it still misses an important aspect of natural intelligence. "People tend to treat the brain as if it were made up of color-coded transistors," he explains. "But it's not simply a clever network of switches. There are lots of important things going on inside the brain cells themselves."
Right now, the notion that conventional computers and software are fundamentally incapable of matching the processes that take place in the brain remains controversial. But if it proves true, then the efforts of Conrad and his fellow AI rebels could turn out to be the only game in town.
The author says that the powerful computers of today ____ .
31.
A) are capable of reliably recognizing the shape of an object
3d综合版
B) are close to exhibiting humanlike behavior
C) are not very different in their performance from those of the 1950's
D) still cannot communicate with people in a human language
•正确答案：D
The new trend in artificial intelligence research stems from _____ .
32.
A) the shift of the focus of study on the recognition of the shapes of objects
B) the belief that human intelligence cannot be duplicated with logical, step-by-step programs
C) the aspirations of scientists to duplicate the intelligence of a ten-month-old child
D) the efforts made by scientists in the study of the similarities between transistors and brain cells
•正确答案：B
Conrad and his group of AI researchers have been making enormous efforts to_____ .
33.
A) find a roundabout way to design powerful computers
B) build a computer using a clever network of switches
C) find out how intelligence develops in nature
D) separate the highest and most abstract levels of thought
•正确答案：C
What's the author's opinion about the new AI movement?
34.
A) It has created a sensation among artificial intelligence researchers.
B) It's a breakthrough in duplicating human thought processes.
C) It's more like a peculiar game rather than a real scientific effort.
D) It may prove to be in the right direction though nobody is sure of its future prospects.

Which of the following is closest in meaning to the phrase “the only game in town” (in Para.4)?
35.
A) The only approach to building an artificially intelligent computer.
B) The only way for them to win a prize in artificial intelligence research.
C) The only area worth studying in computer science.
D) The only game they would like to play in town.
•正确答案：A

Passage Two
Questions 36 to 40 are based on the following passage.
It is a devastating prospect. Terrorists electronically break into the computers that control the water supply of a large American city, open and close valves to contaminate the water with untreated sewage or toxic chemicals, and then release it in a devastating flood. As the emergency services struggle to respond, the terrorists strike again, shutting down the telephone network and electrical power grid with just a few mouse clicks. Businesses are paralysed, hospitals are overwhelmed and roads are gridlocked as people try to flee.
This kind of scenario is invoked by doom-mongers who insist that stepping up physical security since the September 11th attacks is not enough. Road-blocks and soldiers around power stations cannot prevent
