not ....until 主从句的时态是如何

来源:www.bynmqn.com 2025-02-13

       依据下面的例句,你应该自己找到答案:

      I did not begin work until he had gone.  直到他走了我才开始工作。(从句动作先于主句动作,主句用一般过去时,从句用过去完成时)

      He didn't arrive until I returned. 直到我回来他才到。(主句、从句都用一般过去时)

      He didn't wait until I returned . 他没等到我回来。(不可以译为:直到我回来他才等。)(主句、从句都用一般过去时)

      I had not understood the problem until he explained it. 直到他对这个问题作知道释,我才弄了解。(从句用一般过去时,主句用过去完成时)

      I will not start until the rain lets up.我要等雨停之后才出发。(主句用一般以后时,从句用一般目前时)
