单选题 Which of the following sentences is CORRECT?

A、 I read five English novels by the end of last year.
B、 It's the first time she goes to a museum.
C、 The couple have been busy preparing for their wedding lately.
D、 Since we met last night, there has been no need for me to introduce myself.

【正确答案】 C

【答案解析】时态题。分析四个选项可知，C项使用现在完成进行时，表示到目前为止持续在做的事情，语法正确，故为答案。A项中，时间限定为by the end of last year，谓语动词应使用过去完成式；B项中，It's the first time...句型中，谓语动词应使用现在完成式；D项since意为“既然”，引导原因状语从句，主句应使用一般现在时。
