“Billy! It is February 25, 2099, seven o'clock. Time to get up and go to school，” said the clockrobot in a mental voice. Then the kitchenrobot gave him toast and eggs. Billy was amazed. While he was eating, the whole wall became a TV screen and Billy thought that it was great having robots to do everything for him. Billy ate his meal, watching a TV show. When he finished eating, the clothesrobot gave him his clothes very fast and dressed him. Then Billy went off to school.
When Billy went outside, he saw a car with no driver waiting for him. The car said, “Hello, I will be driving you to school every day. Now would you please show your school ID card？” said the car.

The plan: turn Mars into a blue world with streams and green fields, and then fill it with creatures(生物) from the earth.This idea may sound like something from a science fiction (科幻小说), but it is actually being taken seriously by many researchers.
This suggested future for the “red planet” will be the main topic for discussion at an international conference hosted by NASA (美国宇航局) this week.Leading researchers as well as science fiction writers will attend the event.It comes as NASA is preparing a multibilliondollar Mars research programme.“Turning Mars into a little earth has long been a topic in science fiction，”said Dr Michael Meyer, NASA's senior scientist for astrobiology (太空生物学)．“Now, with scientists exploring the reality, we can ask what are the real possibilities of changing Mars.”
Most scientists agree that Mars could be turned into a little earth, although much time and money would be needed to achieve this goal.
But many experts are shocked by the idea.“We are destroying our own world at an unbelievable speed and now we are talking about ruining another planet，” said Paul Murdin, of the Institute of Astronomy, Cambridge, UK.Over the past months, scientists have become increasingly confident they will find Martian life forms.Europe and America's robot explorers have found proof that water, mixed with soil, exists in large amounts on the planet.
In addition, two different groups of scientistsannounced on March 28 that they had found signs of methane (甲烷) in the Martian atmosphere (大气)．The gas is a waste product of living creatures and could be produced by microbes (微生物) living in the red planet's soil.
But scientists such as Dr Lisa Pratt, a biologist at Indiana University, say that these microbes will be put in danger by the little earth project.“Before we have even discovered if there is life on Mars, we are talking about carrying out projects that would destroy all these native life forms, all the strange microbes that we hope to find buried in the soil，” said Dr Pratt.This view is shared by Monica Grady, a planetary scientist at the Natural History Museum, London.“We cannot risk starting a global experiment that would wipe out the precious information we are looking for.” she said, “This is just wrong.”
20．The passage is about________.
A．a plan turning Mars into a little earth
B．the necessity of changing Mars
C．Mars supporting life
D．finding water in the Mars
21．Which of the following is NOT the reason why some scientists are against the plan?
A．The project would wipe out all the native life forms on the Mars.
B．The project will cost too much money and work.
C．We would ruin Mars.
D．We are destroying our own world at an unbelievable speed.
22．We can infer from the passage that________.
A．water is a crucial factor for life
B．the project will have little effect on the native life forms supposed to live on the Mars
C．Monica Grady is in favour of carrying out the little earth project
D．the idea turning Mars into a little earth is nothing but a science fiction
23．Which of the following supports the conclusion of microbes living in the Mars soil?
A．Scientists found liquid water in the Mars.
B．Scientists found signs of methane in the Martian
atmosphere.
C．Scientists found a lot of good soil on the Mars.
D．Scientists found some creatures living on the Mars.
答案
课时作业(二十三)
Ⅰ.1.B 考查交际用语。句意：“好啦，亲爱的，我得起程了。”“千万小心点，愿上帝保佑你在利比亚平平安安。”此题很容易错选送行时的常用语：have a nice trip。但要去的地方是利比亚，一个充满动乱、很危险的地方，因此他(她)不可能是去游玩享乐的，因此A、C两项都不恰当。后者在送行时最应该说的是祝前者在利比亚平平安安。
2．C 考查介词短语搭配。句意：火车以每小时120公里的速度行驶。在表达“以……的速度”时候．应用at a/the speed of。
3．C 考查非谓语动词。句意：要说出来真的很令人害羞，但是在会上受到老板责问时我说谎了。 “when＋分词”作状语，question为及物动词，意为“对……提出疑问”，故应用过去分词形式表示其与主语之间有被动含义。
4．D 考查状语从句的省略。句意：当问到当今最大的问题之一时，许多人说正面临能源危机，并且它也正威胁着人类的生存。D项在此处表被动，相当于when they are asked。
5．C 考查动词短语辨析。句意：在医科大学学习了五年后，简在乡村从事医生的工作。take up意为“从事”，可根据as a doctor判断。
6．D 考查名词辨析。句意：他脸上的表情向我表明他生气了。impression “印象，印记”；appearance “外貌，露面”；expression “神色，表情，表达”，此处是指他脸上的表情。
7．B 考查非谓语动词。句意：托尼既惊讶又高兴，站起来接受了这个奖项。分析句子结构以及and后的并列词happy可以看出，此处是需要形容词作状语，说明主语托尼目前的心理状态。
8．A 考查非谓语动词。句意：大部分被邀请参加聚会的艺术家来自南非。此处是过去分词作后置定语，表示完成和被动。这里艺术家是被邀请的，故用invited。
9．D 考查连词。句意：格拉斯哥的生活花销在英国是最低的，但是生活的质量可能是最高的之一。根据句中的among the lowest in Britain和probably one of the highest可知前后的意义存在对比，while用作并列连词，可用于对比的情况，意为“而，但是”。
10．B 考查名词性从句与强调句式。句意：不是你所说的而是你所做的让我生气。本文第一空为与not what you said并列的主语从句；第二空为强调句的that，强调并列的主语从句not what you said but what you did。
11．A 考查动词短语辨析。句意：充足的蔬菜和水果会加快你的康复。speed up加快，加速；sweep up打扫；put up举起，张贴，建起。
12．A 考查介词短语搭配。句意：一瞬间，他想到了曾让他伤心的爱。for an instant 瞬间。
13．C 考查consider的用法。句意：你知道是谁被认为发明了电话吗？由于consider表示“考虑，打算”，其后接动名词，本题易误选A或B。但是这里的consider“认为”用作被动语态，其后应是补充说明who的。由于invent的动作在consider之前发生，故应用不定式的完成式。
14．A 考查动词的时态。句意：我们很久未收到戴安娜的来信了。你认为她会发生什么事呢？ happen后接to，此题应用现在完成时态表示与现在有关的情况。本题是一特殊句型，为双重疑问句，做题时也可把do you think看作插入成分。
15．C 考查冠词用法。句意：从一万米高的地方跳出飞机是一次非常令人兴奋的经历。前一空格中不定冠词与可数名词单数形式连用表示类别；因本题中experience被exciting修饰，表示“一次经历”，其前应该用不定冠词。
Ⅱ.A
未来的生活会是什么样的呢？文章通过一个学生未来的生活，向我们展示了一个全自动化的未来世界。
16．C 主旨大意题。文章所叙述的是，在未来社会机器人帮助我们人类处理日常事务的故事。
17．C 事实细节题。由第一段的Then the kitchenrobot gave him toast and eggs.可知。
18．B 事实细节题。由第二段可知。
19．C 事实细节题。由最后一段可知，作者并没有说上课的老师也是机器人，所以C项错误。
B
本文是议论文，描绘了把红色火星改造成蓝色的“生命天堂”的宏伟规划，综述了科学家对这个火星改造工程所持的不同观点。
20．A 主旨大意题。根据第一段第一句The plan: turn Mars into a blue world with streams and green fields, and then fill it with creatures from the earth.可知这篇短文主要讲的是火星改造计划的设想。
21．B 细节理解题。根据短文所述，科学家反对这个设想的理由有：“We are destroying our own world at an unbelievable speed and now we are talking about ruining another planet”和that would destroy all these native life forms。因此B项不是反对的理由。
22．A 推理判断题。根据第四段…scientists have become increasingly confident they will find Martian life forms.Europe and America's robot explorers have found proof that water, mixed with soil, exists in large amounts on the planet.的内容，我们知道科学家越来越相信火星上存在生命，因为有证据表明火星土壤中存在大量的水，故可断定水是生命存在的关键要素。
23．B 推理判断题。根据倒数第二段…The gas is a waste product of living creatures and could be produced by microbes living in the red planet's soil.可知，火星大气层中存在甲烷的迹象，而甲烷是活着的动物产生的废物，据此科学家推断这可能是生活在火星上的微生物产生的。故可得出结论：火星上可能存在微生物，主要证据是在火星大气层中发现了甲烷的迹象。
