to be用法的总结

  动词不定式可以作以上各种成分,但它毕竟是动词,所以有动词的属性

  动词不定式及其短语还可以有自己的宾语、状语,虽然动词不定式在语法上没有表面上的直接主语,但它表达的意义是动作,这一动作一定由使动者发出.这一使动者我们称之为 逻辑主语,其形式如下:

  主动形式 被动形式

  一般式 (not) to make (not) to be made

  完成式 (not) to have made ( not) to have been made

  进行式 (not) to be making (not)to have been making

  (1)语态

  如果动词不定式的逻辑主语是这个不定式所表示的动作的承受者,不定式一般要用被动语态形式.如:

  It's a great honour to be invited to Mary's birthday party.(不定式作主语)

  It was impossible for lost time to be made up.(不定式作主语)

  I wish to be sent to work in the country.(不定式作宾语)

  Can you tell me which is the car to be repaired?(不定式作定语)

  He went to the hospital to be examined.(不定式作状语)

  在There be结构中,修饰主语的不定式可用被动,也可用主动.如:There are still many things to take care of (to be taken care of).但有时两种形式表达的意思不同,如:These is nothing to do now.( We have nothing to do now.) There is nothing to be done now.(We can do nothing now.)
