表示过去的过去不是该用过去完成时吗? 但为何在 until+过去的时间点(到过去某个时间点为止)的句型中却不用呢? 这是摘自GWD的几个正确语法句子, Until the passage of the Piracy and Counterfeiting Amendments Act in 1982, a first-time charge of copyright infringement was merely a misdemeanor charge. 后半句描述的是1982年以前的情况,为何不用had been a misdemeanor呢? 同理: 1. until about 25 years ago miners did not realize that bacteria take an active part in the process. 2. Barbara Jordan did not become a nationally recognized figure until 1974. 我觉得这几个句子都用had done 才好呀,
望NN解惑 |
