问题补充：

By now, more than 100 photos back to the earth by Chang’e-3.

A. had been sent

B. has been sent

C. have been sent

D. will be sent

答案：

A. had been sent

B. has been sent

(答案→)C. have been sent

D. will be sent

解析：句意：到现在，超过 100 的照片由嫦娥 3 传回地球。 By now 到现在为止，用于现在完成时中，该句主语是动作的承受者，应用被动语态，故选C。

考点: 考查动词时态和语态的用法。
