II.例题

例1 I haven't got a chair ____.

A to sit B for to sit on C to sit on D for sitting

解析：该题选C。不定式to sit on在句中作定语，修饰名词chair. 因为不定式和它所修饰的名词间是\动宾关系\，所以不定式必须是及物动词，故此处on不能省略。

例2 He was made ____. A go B gone C going D to go

解析：该题选D。make sb. do sth. 如果是被动形式，不定式do前的to不能省略。

例3 A new factory is ____ very soon.

A to be built B built

C to build D to building

解析：该题选A。is to be built意为\将要被建\。
