參考答案：C
參考解析： 參考譯文
1994年7月，太陽系最大的行星，丘位元，被一個彗星的21個碎片撞擊了。當碎片在這個巨型行星的南部著陸時，科學家在地球上就可以看到這些爆炸。但是如果我們的地球被彗星撞擊的話，後果是什麼呢?
這件事將發生在2094年。據宣佈，一個彗星正朝地球執行。它的大部分碎片會與地球擦肩而過，但是有兩片可能會撞到地球的南部。這條訊息引起了人們的恐慌。
在7月17號，伴隨一聲巨大的爆炸，一個四公里寬的碎片進入了地球的大氣層。大約一半的碎片被大氣層的摩擦燃燒掉。但是碎片的大部分殘留了下來。它以200倍的聲速撞擊了南大西洋。海洋沸騰了，導致了巨大的海浪，並開始蔓延。水牆以每小時800公里的速度向南非逼近。非洲沿岸的城市完全被破壞，數百萬的人被淹死。海浪衝進印度洋，並且向亞洲襲來。
在地球的南部已經有數百萬的人死亡，但是北部的人們也不會逃脫厄運太久。爆炸將數噸重的.碎片拋向大氣層，太陽被灰塵遮蔽，世界溫度幾乎降到零度。農作物被毀壞，國家之間為了爭奪食物發生戰爭。一年之後，人類文明蕩然無存。倖存的人不超過一千萬。
這真可能發生嗎?事實上，在地球的歷史上，已經發生過數次。恐龍在地球上生存了一億六千萬年。然後，在六千五百萬年前，它們突然消失了。許多科學家們認為地球被一個宇宙碎片撞擊了。恐龍不能在隨後的寒冷氣候下倖存下來，所以他們滅絕了。我們會重複同樣的結束嗎?
答案及解析
C【解析】推理判斷題。作者在這篇科幻小說中描述了2094年7月17日彗星撞擊地球后的情形。在倒數的第二段作者說，A yearlater civilization has more than l0 million people havesurvived.而不是人類在地球上滅絕了。extinct意為“滅絕”。所以正確的答案為C。

閱讀下列短文,回答{TSE}題目.
Some people make you feel comfortable when they are around. These people have something in common. And once we know what it is we can try to do it ourselves.
How is it done? Here are several skills that good talkers have. If you follow the skills, they' 11 help you put people at their ease, and make friends with them quickly. First of all, good talkers ask questions. Almost anyone, no matter how shy he is, will answer a question. And how he answers will let you know how far you can go.
Second, once good talkers have asked questions, they listen to the answers. And to find out what sort of person you are talking to, you really have to listen carefully and attentively.
Real listening at least means some things. First it means not to change the subject of the con- versation. Real listening also means not just listening to words but to tones of voice. If the voice sounds dull, then, it' s time for you to change the subject.
Finally, good talkers know well now to deal with the occasion of parting. If you want to see that person again, don' t keep it a secret. Let people know what you feel, and they may walk away feeling as if they' ve known you half their life.

閱讀下列短文,回答{TSE}題目.
Thousands of years ago man used handy rocks for his surgical operations. Later he used sharp bones or horns, metal knives and more recently, rubber and plastic. In the 1960s a new tool was developed, one which was, first of all, to be of great practical use to the armed forces and indus- try, but which was also to revolutionize the art and science of surgery.
The tool is the laser and it is being used by more and more surgeons all over the world. As we all know, light is hot, and any source of light will give warmth. But light is usually spread out over a wide area. The light in a laser beam, however, is concentrated. This means that a light with no more power than that produced by an ordinary electric light bulb becomes intensely strong as it is concentrated to a pinpoint-sized beam.
Experiments with these pinpoint beams showed researchers that different energy sources pro- duce beams that have a particular effect on certain living cells. It is now possible for eye surgeons to operate on the back of human eye without harming the front of the eye, simply by passing a laser beam right through the eye-ball. Operations which once left patients exhausted and in need of long period of recovery time now leave them feeling relaxed and comfortable.
The rapid development of laser techniques in the past ten years has made it clear that the future is likely to be very exciting. Perhaps some cancers will be treated with laser in a way that makes surgery not only safer but also more effective.
{TS} Which of the following would be appropriate to describe the instruments of surgical opera- tions up until 1960s?
itional.
licated.
rkable.
lutionary.
參考答案：A
參考解析： 參考譯文
幾千年前人們就用身邊的石頭做外科手術。後來人們開始使用骨頭或者角、鐵刀，現在在用塑料和橡膠。20世紀60年代，發明了一種新工具，這種新工具首先應用在軍事以及工業上，後來也漸漸地用於改善手術技術及外科學上。
這種新工具就是鐳射，全世界越來越多的人在使用它。我們都知道，任何種類的光都是熱的，都會散發熱量。但是光都會散發得很廣闊。然而鐳射束的光是集中的。這就意味著由普通電燈泡發出的光所產生的能量由於被集中到一起而變得十分巨大。
對這些精尖光束的實驗還表明不同的能源產生的光束能夠對活細胞產生不同的效應。現在眼科醫生僅僅通過讓鐳射束通過眼球就能在後眼球上做手術而不傷害到前眼球。曾經一度讓患者疲憊不堪，並且術後恢復時間漫長的手術現在讓患者變得很輕鬆很舒服。
鐳射技術在過去十年中的迅速發展清楚顯示了鐳射技術的未來還是很樂觀的。也許一些癌症也能夠用鐳射來治療，使得手術不僅更安全而且更有效。
答案及解析
A【解析】事實細節題。題乾的意思是“以下哪個單詞能夠確切描述20世紀60年代以前的手術工具?”A選項的意為“傳統的”;B選項意為“複雜的”;C選項意為“非凡的”;D選項意為“革命的”。原文第一段提到幾千年前人們用石頭、牛角等做手術，由此可以推斷出選項A是正確的。
第28題單選修改

參考答案：D
參考解析：D【解析】事實細節題。題乾的意思是“20世紀60年代鐳射取得發展後我們可以發現什麼?”根據原文第一段最後一句可知“鐳射為外科手術帶來革命性的變化”，故選D。
第29題單選修改
The reason why the laser beam is very strong is that_______
A. it is artificially illuminated
is made up of a concentrated beam of light
sends out heat in all directions
heat is increased by the heat of the sun
參考答案：B
參考解析：B【解析】事實細節題。題乾的意思’是“為什麼鐳射束的能量比較強?”根據原文第二段最後一句可知“能量被集中到一起而變得強大”。故答案為B。
第30題單選修改

e their patients with negative effects
treat only human eye diseases
little damage to their patients
their patients need a long time to recover
參考答案：C
參考解析：C【解析】事實細節題。題乾的意思是“使用鐳射束做手術時醫生可以。文中第三段提到“曾經一度讓患者疲憊不堪，並且術後恢復時間漫長的手術現在讓患者變得很輕鬆很舒服”，可以排除A和D。由文中最後一句“也許一些癌症也能夠用鐳射來治療”可知B選項不正確。C選項意思為“使患者受到很小的傷害”。所以正確答案為C。
