Over the past several decades, the U.S., Canada, and Europe have received a great deal of media and even research attention over unusual phenomena and unsolved mysteries. These include UFOs as well as sightings and encounters with “nonhuman creatures” such as Bigfoot and the Loch Ness monster. Only recently has Latin America begun to receive some attention as well. Although the mysteries of the Aztec, Mayan, and Inca civilizations have been known for centuries, now the public is also becoming aware of unusual, paranormal phenomena in countries such as Peru.The Nazca “lines” of Peru were discovered in the 1930s. These fines are deeply carved into a flat, stony plain, and form about 300 intricate pictures of animals such as birds, a monkey, and a lizard. Seen at ground level, the designs are a jumbled senseless mess. The images are so large that they can only be viewed at a height of 1,000 feet-meaning from an aircraft. Yet there were no aircraft in 300 B.C., when it is judged the designs were made. Nor were there then, or are there now, any nearby mountain ranges from which to view them. So how and why did the native people of Nazca create these marvelous designs? One answer appeared in 1969, when the German researcher and writer Erich von Daniken proposed that the lines were drawn by extraterrestrials as runways for their aircraft. The scientific community did not take long to scoff at and abandon von Daniken’s theory. Over the years several other theories have been put forth, but none has been accepted by the scientific community.Today there is a new and heightened interest in the Nazca lines. It is a direct result of the creation of the Internet. Currently there are over 60 sites dedicated to this mystery from Latin America’s past, and even respected scientists have joined the discussion through e-mail and chat rooms.Will the Internet help explain these unsolved mysteries? Perhaps it is a step in the right direction.1. Which of the following statements is INCORRECT?2. According to the passage, the Nazca lines were found（）.3. We can infer from the passage that the higher the lines are seen, the（）images they present.3. There has been increasing interest in the Nazca lines mainly because of（）.5. The author is（）about the role of the Internet in solving mysteries.

The ideal companion machine — the computer — would not only look, feel, and sound friendly but would also be programmed to behave in a pleasant manner. Those qualities that make interaction with other people enjoyable would be imitated as closely as possible, and the machine would appear to be charming, and easygoing. Its informal conversational style would make interaction comfortable, and yet the machine would remain slightly unpredictable and therefore interesting. In its first encounter it might be somewhat hesitant, but as it came to know the user it would progress to a more relaxed and intonate style. The machine would not be a passive participant but would add its own suggestions, information, and opinions; it would sometimes take the initiative in developing or changing the topic and would have a personality of its own.Friendships are not made in a day, and the computer would be more acceptable as a friend if it imitated the gradual changes that occur when one person is getting to know another. At an appropriate time it might also express the kind of affection that stimulates attachment and intimacy. The whole process would be accomplished in a subtle way to avoid giving an impression of over-familiarity that would be likely to produce irritation. After experiencing a wealth of powerful, well-timed friendship indicators, the user would be very likely to accept the computer as far more than a machine and might well come to regard it as a friend.An artificial relationship of this type would provide many of the benefits that people obtain from interpersonal friendships. The machine would participate in interesting conversation that could continue from previous discussions. It would have a familiarity with the user’s life as revealed in earlier contact, and it would be understanding and good-humored. The computer’s own personality would be lively and impressive, and it would develop in response to that of the user. With features such as these, the machine might indeed become a very attractive social partner.1. Which of the following is NOT a feature of the ideal companion machine?2.

Translate the following text into Chinese. Write your translation on the ANSWER SHEET.Many believe that science is merely a collection of facts, that it develops by the gathering of these facts and slowly approaches the truth about nature. According to this view, the so-called scientific method is the basis for scientific development. The scientific method is said to have three steps.The first step is that of careful observation—often involves looking for relationships among different kinds of events. If a specific relationship seems to be true in a number of cases, without any exceptions, then it may be hypothesized that the relationship holds in general. The second step of the scientific method may be the formulation of such a general hypothesis. Or it may be an attempt to explain phenomena by theorizing the existence of a deeper reality. The third step, the testing of the theory, may involve further experimental testing of hypothesized relationships. Or it may be experimental verification of new phenomena predicted by a new theory.
