Question

【題目】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 (科幻小說), but it is actually being taken seriously by many researchers. This suggests the future for the "red planet" will be the main topic for discussion at an international conference hosted by NASA (美國宇航局) this week. Leading researchers as well as science fiction writers will attend the event.

Turning Mars into a little earth has long been a topic in science fiction,” said Dr Michael Meyer, NASA's senior scientist for astrobiology (太空生物學(xué))．“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 from 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.

【1】The passage is about________.

A. Mars supporting life

C. are asking for advice on how to carry it out

D. realize that it’s not easy to achieve their goal

【3】What’s Paul Murdin’s attitude to the plan?

A. He is for the idea.

B. He is active in the idea.

C. He is against the idea.

D. He doesn’t care about it.

【4】What can we know about the scientists from the last paragraph?

A. They have no idea about the plan.

B. They will find Martian lives very soon.

C. They may achieve their goals some day.

D. They have found much proof of Martian lives.

Answer 1

【答案】

【1】C

【2】D

【3】C

【4】C

【解析】

試題分析：本文是議論文，描繪了把火星改造成藍色的“生命天堂”的宏偉規(guī)劃，綜述了科學(xué)家對這個火星改造工程所持的不同觀點。

【1】C主旨大意題。根據(jù)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.可知這段短文主要講的是火星改造計劃的設(shè)想。故C正確。

【2】D 推理判斷題。根據(jù)文章第四段Most scientists agree that Mars could be turned into a little earth, although much time and money would be needed to achieve this goal.可知同意這個計劃的科學(xué)家也認為要想實現(xiàn)這個目標(biāo)要花掉很多的時間和金錢，并不是一件容易的事情。故D正確。

【3】C 觀點態(tài)度題。根據(jù)第五段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,"可知Paul Murdin認為我們正在毀滅地球，還要計劃去毀滅火星。這一觀點說明他反對這個計劃。故C正確。

【4】C 推理判斷題。根據(jù)文章最后一句Europe and America's robot explorers have found proof that water, mixed with soil, exists in large amounts on the planet.歐美科學(xué)家以后在火星上發(fā)現(xiàn)了水的存在。而水是生命存在必要的元素，也許未來科學(xué)家真的能夠?qū)崿F(xiàn)他們的目標(biāo)。故C正確。
