题目内容
________ we had read your letter _____the true state of affairs.
| A.It was until… that we understood | B.It was not until…that we understood |
| C.Until …did not we understand | D.Not until… we understood` |
B
解析这题考查强调句的用法:It’s not until…that…“直到…才”,句意是:直到我们读了你的信,我们才知道事情的真实情况。如果用not until在句首,从句需要倒装,所以D是错的。选B。
