Question

【题目】If they 　　　　earlier than expected, they 　　　　here now.

A. had started; would be B. started; might be

C. had started; would have been D. will start; might have been

Answer 1

【答案】A

【解析】考查虚拟语气。句意：如果他们比预期早出发，他们现在就在这里。这是一个混合虚拟语气的句子，从句是对过去的假设，故要用had done；主句中有now，是对现在的假设，故要用would/could/might do。故选A。
