  [联想发散] 想一下与have no alternative but to do sth.意思相同的短语还有哪些?

  ①have no choice but_to_do_sth.

  ②can't do sth.but_do_sth.

  ③can/could do nothing but_do_sth.

  2.(教材P57)If only there were more people donating money to charities!

  但愿有更多的人给慈善机构捐款!

  ★if only 只要,但愿,要是......就好了

  if only表示"要是......就好了",指一种不能实现或难以实现的愿望,用于虚拟语气,表示对过去、现在或将来的虚拟。常用于以下几种情况:

  (1)if only表示过去不能实现的愿望,含有后悔、惋惜之意,谓语动词使用had done形式。

  ①If only you had come to help us yesterday!

  你要是昨天来帮我们就好了。

  (2)表达现在不能实现的愿望,谓语动词用一般过去式(be用were)。

  ②If_only_I_were_a_little_younger,_I could travel around the world.

  要是我再年轻一点,我就能环游世界了。

  (3)表达将来难以实现的愿望,谓语动词用"would/could/might+动词原形"。

  ③I am so tired.If only I could take the day off tomorrow.

  我太累了,如果明天能请假该多好!

[名师点津] only if意为"只有,只要",引导条件状语从句,only起强调作用,当only if位于句首时,主句要倒装。
