    Ⅰ、 一般现在时

  注:be about to do 不能与tomorrow, next week 等表示明确的将来时间状语连用。

  ★ 一般现在时表将来

  1)下列动词come, go, arrive, leave, start, begin, return的一般现在时可以表示将来,主要用来表示在时间上已确定或安排好的事情。例如:

  The train leaves at six tomorrow morning. 火车明天上午六点开。

  When does the bus star? It stars in ten minutes. 汽车什么时候开?十分钟后。

  ★ 比较一般过去时与现在完成时

  1)一般过去时表示过去某具体时间发生的动作或单纯叙述过去的事情,强调动作;现在完成时则强调过去发生的动作对现在的造成影响,强调的是结果。

  2)一般过去时常与具体的时间状语连用,而现在完成时通常与模糊的时间状语连用,或无时间状语。

  句子中如有过去时的时间副词(如yesterday, last, week, in 1960)时,不能使用现在完成时,要用过去时。

  (对)Tom wrote a letter to his parents last night.

  Ⅷ、 过去完成时:

  过去以前 过去 现在

  例:She said (that)she had never been to Paris.
