來源:網(wǎng)絡(luò)資源 文章作者:奧數(shù)網(wǎng)整理 2018-02-07 09:23:46

  1) 有些動詞用一般現(xiàn)在時代替完成時:

  hear, tell, learn, write , understand, forget, know, find , say, remember.

  I hear (= have heard) he will go to London.

  I forget (=have forgotten) how old he is.

  2) 句型 " It is … since…"代替"It has been … since …"

  3) It is (= has been) five years since we last met.
