2019高考英语语法考点聚焦：动词不定式(6)
不定式的完成时的特殊用法。
①表示不定式中谓语动词发生的动作先于主句的谓语动词发出的动作。
The novel was said to have been published.
I regret to have been with you for so many years.
seem、appear、be said、be supposed、be believed、be thought、be known、be reported等动词常用于上面句型。
此外，glad、happy、satisfied、sorry、surprised、disappointed后也接完成时，但要注意与一般时的区别。
I’m sorry to keep you waiting for a minute.对不起，请稍等。(说话时还未等)
I’m sorry to have kept you waiting.对不起，让你久等了。(说话时已等了很久)
②不定式的完成时还可表示“过去本想做某事但未做”的虚拟语气。(A)should like to / would like to / would love to + 不定式的完成时。(B)was / were to + 不定式的完成时，表示该做某事或想做但未实现。(C)expect / hope / mean / promise / suppose / think / want/ wish + 不定式完成时，表示过去未曾实现的愿望。
