[单项选择]Only computer scientists understand the architecture of personal computers, and only those who understand the architecture of personal computers appreciate the advances in technology made in the last decade. It follows that only those who appreciate these advances are computer scientists.
Which one of the following most accurately describes a flaw in the reasoning in the argument
A. The argument contains no stated or implied relationship between computer scientists and those who appreciate the advances in technology in the last decade.
B. The argument ignores the fact that some computer scientists may not appreciate the advances in technology made in the last decade.
C. The argument ignores the fact that computer scientists may appreciate other things besides the advances in technology made in the last decade.
D. The premises of the argument are stated in such a way that they exclude any possibility of drawing any logical conclusion.
E. (E) The premises of the argument presuppose that everyone understands the architecture of personal computers.

Lately social scientists have begun to ask if culture is found just in humans, or if some animals have a culture too. When we speak of culture, we mean a way of life a group of people have in common. Culture includes the beliefs and attitudes we learn. It is the patterns of behaviour that help people to live together. It is also the patterns of behaviour that make one group of people different from another group.
Our culture Lets us make up for having lost our strength, claws, long teeth, and other defenses. Instead, we use tools, cooperate with one another, and communicate with language. But these aspects of human behaviour, or "culture", can also be found in the lives of certain animals. Animals Can Make Tools
We used to think that the ability to use tools was the dividing line between human beings and other animals. Lately, however, we have found that this is not the case. Chimpanzees can not onl
A. A chimpanzee can learn to use sign language to make sentences.
B. Other animals can invent tools.
C. Sharing and cooperating are no longer signs of only human behaviour.
D. The line dividing human culture from animal culture is not as clear as we might think.

[单项选择]Invented by American computer scientists during the 1970s, the Internet has been embraced around the globe. During the network’s first three decades, most Internet traffic flowed through the United States. In many cases, data sent between two locations within a given country also passed through the United States.
Engineers who help run the Internet said that it would have been impossible for the United States to maintain its hegemony (统治权) over the long run because of the very nature of the Internet; it has no central point of control.
And now, the balance of power is shifting. Data is increasingly flowing around the United States, which may have intelligence--and conceivably military--consequences.
American intelligence officials have warned about this shift. "Because of the nature of global telecommunications, we are playing with a tremendous home-field advantage, and we need to exploit that edge," Michael V. Hayden, the director of the Central Intelligence Agenc
A. the Internet was invented by American scientists
B. most Internet traffic flowed through the United States
C. the internet has to be under the control of a central point
D. the United States shared their roads for Internet traffic with other countries

[简答题]The computer scientists delegation from Britain ____________(在机场受到了热烈的欢送).

[简答题]

Thirty-five years after computer scientists at UCLA linked two bulky computers using a 15-foot gray cable, testing a new way for exchanging data over networks, what would ultimately become the Internet remains a work in progress.
University researchers are experimenting with ways to increase its capacity and speed. Programmers are trying to imbue Web pages with intelligence. And work is underway to re-engineer the net- work to reduce spam and security troubles.
(46) All the while threats loom: critics ware that commercial, legal and political pressures could hinder the types of innovations that made the Internet what it is today.
Stephen Crocker and Vinton Cerf were among the graduate students who joined UCLA professor Len Kleinrock in an engineering lab on Sept. 2, 1969, as bits of meaningless test data flowed silently between the two computers. By January, three other "nodes" joined the fledgling network.
