14.Terraforming (Earth-forming) other planets,also known as planetary engineering (行星工程),seems like a task still centuries away for mankind to accomplish.However,it is a vigorous topic that attracts both popular and scientific interest.Why should the possibility of terraforming other planets be studied when it may be centuries before we know enough to even decide if it's a good idea?Mankind is getting more and more hard facts about other planets.The atmosphere of Venus has been explored; robots have surveyed the surface of Mars; Mercury,Jupiter and Saturn have been studied by spacecraft. Speculations have been answered;new questions have been raised,and enough hard data is right now becoming available to allow us to make the first attempt of planetary engineering.
In the past,people with excellent ideas about terraforming have kept them to themselves,or buried them in a desk drawer because they did not realize that anyone else was interested.But now,a wide circle of people has begun to do this kind of work.For instance,NASA funded a project on transforming Mars.
There are several strong reasons which demand that the possibilities of terraforming be studied carefully.First,it's an exciting idea of a possible future for human beings.Such thinking has a valuable role in providing options for our future directions.Secondly,the techniques of terraforming will also help contemporary technologies in weather and climate control.Thirdly,such study may assist us in detecting any possible existence of extraterrestrial(地球外的)intelligence and alien civilizations on other planets.
Though the mission is far beyond our reach at the moment,we should at least keep our options open.Through debate and study on this subject,the possibility of rebuilding other planets to make them suitable homes for people may come true some day in the future.
84.According to the context,what's the meaning of the word"Speculation"in paragraph 2?C
A.The act of discussing something with a group of people.
B.The act of studying and researching.
C.The act of guessing without knowing all the facts about something.
D.The acting of writing letters to a certain organization.
85.Why did people keep the idea of terraforming to themselves in the past?A
A.They thought no one else would show interest in the idea.
B.They gradually came to find the idea crazy.
C.They thought the idea would never come true.
D.They had few resources for further study on this topic.
86.Which is NOT the reason to support the study of terraforming?D
A.Even if we don't succeed in terraforming,such study may help us to better understand technologies such as climate and weather control.
B.Such study may explore a new direction of development for human beings.
C.Such study may enable us to find the lives on other planets.
D.As the resources on Earth are being drained,it's very urgent to study how to migrate to other planets.
87.What's the main idea of the article?B
A.It's highly possible that terraforming other planets will come true so we should increase investing in this program.
B.Even if the idea of terraforming other planets may take centuries to realize,we have many reasons to support such studies.
C.Terraforming other planets is the best option for human being's future.
D.More and more people are taking planetary engineering as their occupation.
分析 文章主要讲述了关于为什么要改造其他行星的理由,以及主张大家支持改造其他行星.
解答 84.C 词意猜测题.根据文章内容,Speculations have been answered;new questions have been raised,and enough hard data is right now becoming available to allow us to make the first attempt of planetary engineering.在什么都不清楚的情况对某些事物进行猜测已经被回复了,新问题已经被提出,足够的数据已经成为可能…结合选项,故选C
85.A 细节理解题.根据文章第三段"In the past,people with excellent ideas about terraforming have kept them to themselves,or buried them in a desk drawer because they did not realize that anyone else was interested."可知在过去,那些对地球改造有很好的想法的人把他们自己放在了自己的地方,或者把他们埋在书桌的抽屉里,因为他们没有意识到其他人也很感兴趣.故选A.
86.D 细节理解题.根据文章第四段内容可知支持地球话研究的原因有:1、更好地了解气候和天气控制等技术.2、为人类探索一条新的发展方向.3、可能使我们能够找到其他行星上的生命.结合选项故选D.
87.B 细节理解题.根据文章最后一段第一句"Though the mission is far beyond our reach at the moment,we should at least keep our options open."即使改造其他行星可能需要几百年才能实现的想法,我们有很多理由来支持这样的研究.故选B.
点评 本文是科教类阅读理解.做这类题材阅读理解时要求考生对文章通读一遍,做题时结合原文和题目有针对性的找出相关语句进行仔细分析,结合选项选出正确答案.推理判断题也是要在抓住关键句子的基础上合理的分析才能得出正确答案,切忌胡乱猜测,一定要做到有理有据
