应该是E，A 和E之间，用TO 和FOR表目的，都是可以的。但A有3大错误。 1 即使HOPE THAT 的引导词THAT可以省略，但从句中的主语是肯定不能省略的。就是hope STH will enable them to... 2 ENABLE用法请注意，ADVANCED OXFORD里的例子， The software enables you to access the Internet in seconds. Insulin enables the body to use and store sugar. 因此，ENABLE这里的动作发出者一定是NEAR.后面的them就是科学家。A缺少了最为关键的从句主语。在这个ENABLE用法上，A,B,D是错的。 有的认为改变了句意，但讲NEAR的目的就是要AND后面的内容。 C中用them指代NEAR，所以错了EVER 位置也不对。以上有人说有比较级就有THAN,这是GMAT严谨的地方。 最后答案是看来最长的E。用IT来指代NEAR。也许大家惊讶为啥用DID.可以从NASA美国宇航局网站看出，这是第二次NEAR的活动了。 http://solarsystem.nasa.gov/missions/profile.cfm?MCode=NEAR  | NEAR Shoemaker: NEAR was NASA's first Discovery Program spacecraft to be launched and the first spacecraft to orbit and on the surface of an asteroid. After a flyby and imaging run past asteroid 253 Mathilde in 1997, NEAR began orbiting asteroid 433 Eros on February 14, 2000. The spacecraft returned the highest resolution images made of an asteroid at the time, as well as measuring its size, shape, mass, mass distribution, gravity and magnetic field. On February 12, 2001, the spacecraft made the first controlled descent to the surface of an asteroid, snapping an incredible series of 69 close-up photos of the rocky surface. After landing, the spacecraft sent back data from the surface of Eros for two weeks. Read More About NEAR Shoemaker |
