More than 100 students in that school abroad for further study so far.

A. are sent

B. were sent

C. had been sent

D. have been sent

答案：

A. are sent

B. were sent

C. had been sent

(答案→)D. have been sent

解析：考查时态。句意：到目前为止，那个学校已经有100多人被送往国外深造了。本题考查现在完成时和被动语态，so far常与现在完成时连用，student是和send是动宾关系，即，学生是被派往国外的，应该使用被动语态，故选D。
