Ⅲ补充语法:

  定语、状语和补语。 常用来表示未来要做的事,以及愿望、打算、决心等

  例句:Anyone wanting to understand the industry of the future will have to know about robotics.

  (另外不定式还可以作一些形容词的宾语,如:able, unable, afraid , willing, sure, free, please, sorry , ready , glad, eager)

  4.定语

  不定式作定语一定要放在所修饰的中心词之后。

  (1)With the ability to “see”, robots can identify and inspect one specific class of objects out of a stack of different kinds of materials.

  (2)These future robots, assembled with a sense of touch and ability to see and make decisions, will have plenty of work to do.

  注意:I notice him leave the classroom.(宾语补语可省略不定式符号to)

  He is noticed to leave the classroom.(主语补语不可省略不定式符号to)

  表示感觉类的词,后面的宾语补语可以省略,但这类词所在的句子如果变为被动语态,
