Grammar - Infinitives 二、动词不定式作宾语补足语 Grammar - Infinitives 1 不定式作宾语补足语，与宾语构成复合宾语（名词 / 代词 + 不定式），形成逻辑上的主谓关系。常见的接不定式作宾语补足语的动词有 advise, allow, ask, consider, expect, force, invite, like, persuade, want, wish 等。 His fans expected him to be the winner of the singing contest. The famous singer invited many friends to come to her wedding. Grammar - Infinitives 2 在有些动词之后的宾语补足语结构中，不定式符号 to 必须省略。 A. 在 have, let, make 等使役动词之后的复合宾语中用不带 to 的不定式。 The interviewer made Peter wait outside. B. 在 feel, hear, notice, see, watch 等感官动词之后的复合宾语中用不带 to 的不定式。 Mother didn’t see Christine come in and go upstairs. 但使役动词和感官动词为被动语态时，其后仍用带 to 的不定式，试比较： 1) They often hear Tom sing. 2) Tom was often heard to sing this song. 2.
