could you tell me if he_______finish the work on time?A.could B.was able to C.is able to D.would be able选哪个?为什么?
C
Could 用于句首表示一种委婉的语气,不表示过去时,所以排除 A,B,D,
另外,if 引导的条件状语从句 用一般现在时 表示将来.进一步确定选C.
开心.

A
首先D可以排除掉，be able to, to 不可省略。再者，看句子就知道是过去时态，所以可以排除C。然后这是一般疑问句，询问某人的能力水平一般用can 或者could. be able to 在表达某人能够做什么的时候，一般不用于疑问句当中，而是陈述句比较多。
希望能对你有帮助。什么a啊，答案都选c，我只是想确认一下...

C could 表示请求，此句是一般现在时，if 引导的是宾语从句，译为“是否”。而不是条件状语从句。这个句子译为“你能告诉我他是否能按时完成工作？”。
