18、Responding to the public's fascination with-and sometimes undue alarmover-possible threats from asteroids, a scale developed by astronomers ratesthe likelihood that a particular asteroid or comet may collide with Earth.
A. a scale developed by astronomers ratesthe likelihood that a particular asteroid or comet may B. a scale that astronomers have developedrates how likely it is for a particular asteroid or comet to C. astronomers have developed a scale torate how likely a particular asteroid or comet will be to D. astronomers have developed a scale forrating the likelihood that a particular asteroid or comet will E. astronomers have developed a scale thatrates the likelihood of a particular asteroid or comet that may.
google了一下原文，NYTIMES上的，我认为还是d，c 从语法说没错，尤其是be likely to do的用法，但是感觉rate how likely不如rate the likelyhood自然,d 更贴近原作者的表达。
Astronomers Adopt Doomsday Index By ANAHAD S. O'CONNOR Published: July 27, 1999 SIGN IN TO E-MAIL PRINT
To help deal with public fascination -- and sometimes undue alarm -- about possible threats from asteroids, astronomers have adopted a scale that rates the likelihood that a particular asteroid or comet will collide with Earth.
A 0 indicates that there is no chance of impact and a 10 means certain catastrophe on the scale, which was endorsed on July 22 by the International Astronomical Union.
The scale was created by Dr. Richard P. Binzel, professor of Earth, Atmospheric and Planetary Sciences at the Massachusetts Institute of Technology and is named the Torino Impact Hazard Scale, after the Italian city in which it was first proposed.
The major benefit to the scale is that it can be used by both the scientific community and the public in determining the likelihood of an impact, Dr. Binzel said. ''Scientists haven't done a very good job of communicating to the public the relative danger of collision with an asteroid,'' he said, adding that he hoped the scale would help astronomers ''clearly inform but not confuse or unnecessarily alarm the public.''
我选C 首先分句以resonpding开头，很显然，主句要找到它的逻辑主语，排除A,B E也很好排除，that从句做定语修饰asteroid or comet，使得句子变成了asteriod or comet的概率，而不是他们撞击地球的概率，改变逻辑意思。 C选项正确，to do表达目的时比D选项的for doing要清晰，并且这里will be to不是连在一起看的，是(how likely the asteroid or comet will be) to....相当于sth/sb is likely to do的用法。
