不定式的完成时与一般现在时有什么区别
还有 不定式怎么表示将来

Answer 1

1.不定式的一般式表示当作有时与谓语动词表示的动作同时发生,也有时发生在谓语动词表示的动作之后,如：
①He seems to know this.
②He hopes to see you again.
③(87高考) He is preparing _A___ to the seaside.
A. to go B. to have go C. to be going D. to have been going
2.不定式的完成式表示动作发生在谓语动词表示的动作之前,如：
①I’m sorry to have given you so much trouble.
②(93高考) Charles Babbage is considered C the first computer.
A. to invent B. inventing C. to have invented D. having invented
3.现在分词做定语表进行, 过去分词做定语表完成,而不定式做定语表将来,如：
①The house _A__ in 1949 is still in use at the present time.（过去分词表完成,表示修建于1949年的房子）
②The house __B___ now will be used as our library.（现在分词表进行,表示是现在正在修建的房子）
③The house __C___ next year will be 5 storeys high.(动词不定式表将来,表示是明年将会建造的房子)
A. built B. being built C. to be built D. was built
