Question

She has set a new record, that is, the sales of her latest book ________ 50 million.

1. A.
   have reached
2. B.
   has reached
3. C.
   are reaching
4. D.
   had reached

Answer 1

A
解析：
因为that is意为“换句话说，即 (="in" other words, which means)”，而前句中的谓语has set是现在完成时，后一句的谓语动词也应用现在完成时，排除C和D；
又因主语the sales是复数，选出正确答案A。
