GWD-26-Q17

Responding to the public’s fascination with-and sometimes undue alarm over-possible threats from asteroids, a scale developed by astronomers rates the likelihood that a particular asteroid or comet may collide with Earth.

A.     a scale developed by astronomers rates the likelihood

that a particular asteroid or comet may

B.     a scale that astronomers have developed rates how

likely it is for a particular asteroid or comet to

C.    astronomers have developed a scale to rate how likely

a particular asteroid or comet will be to

D.    astronomers have developed a scale for rating the

likelihood that a particular asteroid or comet will

E.     astronomers have developed a scale that rates the

likelihood of a particular asteroid or comet that may.

Answer is C. I can't understand"will be to", and some guys choose D

偶不是NN，个人认为：答案应该是D。E有问题，改变原句修饰的重心（likelihood of有问题）；C也应该不对，动词rate后应优先使用名词，C中用的是从句；

再者will be to 表示主观意原，按XDF对be to do 解释be to do =be going to do表主观色彩的将来。

OG10-134中will的用法及OG84中的C、D的错误项可能对will be 的理解有一定的帮助。
