  2. hope 和 wish 的连系与区别

  hope 一般侧重于表达有可能实现的愿望,故常译为“希望”。

  Wish 一般侧重于表达不大可能实现或根本不考虑是否可能实现的愿望,故常译为“但愿”。


  1) 表示“想”、“希望”时,均接不定式做宾语。如:

  I hope (wish)to come tomorrow。我希望(但愿)明天能来。

  2)均可与 for 连用。如:

  Let’s hope for the best。让我们尽量往好处想。

  He wishes for a dictionary。他想得到一本词典。


  1) hope 和 wish均可接宾语从句。Wish常用虚拟语气,表示一种无法实现的或不真实的愿望;而hope 用陈述语气,表示很有把握实现或得到。如:

  I wish I were bird 。但愿我是一只

  I hope she won’t come together 。我不希望她今晚来。

  2)wish 后通常接“宾语+不定式(宾补)”,而hope 不行,如:

  My parents wish (不用hope)me to grew up quickly 。我父母希望我快快长大。

  3) wish 可接双宾语,表示“祝愿”,而hope 不能。如:

  I wish (不用hope)you well and happy。我祝你健康幸福。

  4)作简略回答时,hope 后可用替代词so 或not ,而wish 不能。如:

  ——will it be fine tomorrow?明天会是晴天吗?——I hope so。我希望是(晴天)。
