Mars is the obvious first choice for travel to other planets. Of all the other planets in the Solar System, Mars even with its present

21、s it closer to Earth, and its presence in the night sky is a constant reminder of what might be.

In c
22、ontrast, Mars is pleasantly cool, from about 200 degrees below zero right up to freezing. From the presence of water and relatively temperate climate comes another powerful attraction. “The fascination with Mars centers around the issue of life,” Dr. Zubrin said. “Mars is key to answering that criti
23、cal question, is there life somewhere other than Earth?” Dr. Louis D. Friedman, executive director of the Planetary Society, said, “The fundamental question people want answered is Where am I from and where am I going?” He added, “Mars can tell us about the origin of life and the destiny of life. Fi
24、nding evidence of past or present life, even if only primitive microbes, would mean that life did not occur only on Earth”, he said. “And”, he said, “Mars is the only planet we know of that humans have a chance of colonizing to prove they will not be forever Earth-bound.” “Mars becomes the experimen
25、t,” Dr. Friedman said. “If we cant make it on Mars, then Earth is our limit and we are going to have to re-examine our relationship to our home planet.” (1)Mars is the obvious first choice for travel to other planets, because_. 本题2分 正确答案：B (A) Mars is cold and hostile (B) The environment of Mars is

(3)According to Dr. Zubrin, people are fascinated with Mars because _. 本题2分 正确答案：C (A) Mars has water beneath

For over a decade, the technique of distraction has been researched and successfully applied in clinical practice in order to reduce pain associated with certain medical procedures. Distraction techniques are based on the patients limited cap
31、acity for attention, resulting in a reduction in the patients attention to the stimulus and therefore a reduction in the stimulus itself. It was assumed that the ideal distracter would require an optimum amount of attention involving various senses (visual, auditory and kinesthetic), an active emoti
32、onal involvement, and participation from the patient to compete with the signals of the harmful stimuli. The advanced distraction techniques (ADTs) recently developed use 3D images combined with dynamic audio stimuli, making the techniques more likely to meet the requirements of an ideal distracter
33、than the traditional distraction methods such as watching a film or playing a simple computer game. The ADTs simulate real-life situations, and the possibilities are infinite. For example, until now users could choose between taking a flight, driving, downhill skiing, exploring buildings and many mo
34、re activities. In this study, peer-reviewed publications on ADTs and pain have been reviewed to determine the clinical effectiveness and importance of using these techniques as an analgesic. The results suggest that the ADTs can significantly reduce the pain associated with medical treatment. The us
35、e of such analgesia was clinically revealed in most cases, especially in patients with very high or unbearable levels of pain. It was found that levels of anxiety were reduced during the exposure, and the side effects, such as simulator sickness, were hardly observed at all. We can conclude that ADT
36、s are very useful as analgesia, and can reduce the amount of analgesic administered. This new field of study can begin to move forward beyond its current initial phase by placing more emphasis on methodology and psychological aspects. (1)Which is NOT the reason why distraction techniques can reduce
37、the patients pain? 本题2分 正确答案：A (A) Because distraction techniques can remove the pain out of the patients body. (B) Because distraction techniques are based on the patients limited capacity for attention. (C) Because distraction techniques can cause a reduction in the patients attention to the stimu
38、lus and therefore a reduction in the stimulus itself. (D) Because distraction techniques would require various senses, an active emotional involvement, and participation from the patient to compete with the signals of the harmful stimuli. (2)That ADTs is better than the traditional distraction metho
39、ds because _. 本题2分 正确答案：C (A) ADTs include watching a film or playing a simple computer game. (B) ADTs require people to take a flight, driving , downhill skiing, exploring buildings, etc. (C) ADTs use 3Dimages combined with dynamic audio stimuli. (D) ADTs are used in real-life situations. (3)Accord
40、ing to Para. 4, when ADTs are used, which of the following will NOT happen? 本题2分 正确答案：A (A) The pain associated with medical treatment has completely gone. (B) Levels of anxiety were reduced during the exposure. (C) The side effects, such as simulator sickness, were hardly observed at all. (D) ADTs
41、can significantly reduce the pain relevant to medical treatment. (4)From the last paragraph, we know that_. 本题2分 正确答案：B (A) The effect of ADTs are the same as that of analgesia. (B) We can reduce the amount of analgesia with the help of ADTs. (C) We can replace analgesia with ADTs. (D) We have alrea
42、dy achieved success in the study of distraction techniques. (5)This passage mainly talks about_ 本题2分 正确答案：A (A) distraction techniques that help ease pain during medical treatment. (B) the relation between ADTs and traditional distraction methods. (C) the advantages of using ADTs over analgesic. (D)
43、 the difference between ADTs and traditional distraction methods. 43. How can we get rid of garbage (垃圾)? Do we have enough energy sources to meet out future energy needs?
