Lucy is my friend. She _________in this school since she came here.

A. has studied B. will study C. am studying D. studied

【答案】

A

【解析】

解析：句意：露西是我的朋友。自从她来到这里，她就在这所学校学习。A. has studied现在完成时；B. will study一般将来时；C. am studying现在进行时；D. studied一般过去时；since引导的时间状语从句，从句用一般过去时，主句要用现在完成时。现在完成时的构成为：have/has+动词的过去分词，主语是she，助动词用has，study的过去分词为studied；结合选项，故选A。
