13.A scientist responsible for finding signs of life on other planets has warned that human beings should probably think twice before making contact with aliens(外星人).
Professor Matthew Bailes is based at Swinburne University and is leading Australia's efforts to find signs of extra-terrestrial (外星的)life.But he warned that making contact with aliens capable of transmitting powerful signals to earth over tens of thousands of light years could lead humans into disaster,because they're likely to be so much advanced."The history of weak civilizations contacting more advanced civilizations is not a happy one!"he said.
Prof Bailes was recently put in charge of the Breakthrough Prize Foundation's $100m to search for alien life,which is being financed by Russian billionaire Yuri Milner and is backed by Professor Stephen Hawking.The team working on the project will use the Parkes radio telescope,one of the largest in the world,to scan the universe.
Prof Bailes told the news media that accurate computers would have to be installed at Parkes to sort through as many as a billion samples a second to try to detect patterns or likely signals."There is no manual(指南) on how to find aliens.We'll have to imagine the sort of transmissions an alien race might send."
The computers,he warned,would take a year to build,and the project has five years to run.But he said that the signal,if and when it arrives,would likely be quite weak after travelling across such vast distances.He said that scientists hope that aliens will send a pattern human beings would be able to recognize,such as prime numbers.But he warned that we might all be"long dead and buried"before we could work out how to reply and the aliens could get an answer.

分析 短文主要講了科學家認為外星人對我們還是存在一定的危險,提醒人類要慎重與外星人接觸.
解答 32.D,細節(jié)理解題,根據(jù)句子A scientist responsible for finding signs of life on other planets has warned that human beings should probably think twice before making contact with aliens(外星人).可知,科學家提醒人類不要經(jīng)常聯(lián)系外星人,故答案為D.
33.B,細節(jié)理解題,根據(jù)句子But he warned that making contact with aliens capable of transmitting powerful signals to earth over tens of thousands of light years could lead humans into disaster,because they're likely to be so much advanced可知,外星人的文明發(fā)展可能比人類更先進,故答案為B.
34.D,推理判斷題,根據(jù)句子Prof Bailes told the news media that accurate computers would have to be installed at Parkes 可以推測,Parkes的設(shè)備那時還沒被安裝,故答案為D.
35.C,態(tài)度觀點題,根據(jù)句子The history of weak civilizations contacting more advanced civilizations is not a happy one!可知,Bailes認為人類跟外星人接觸的結(jié)果是不好的,故答案為C.
