Tom refused ()(lend )me his pen The girl decided ()(do)it herself 2.动词不定式作宾补 (1)带to的不定式作宾补的动词有： ask,allow,permit,advise,expect,suppose,invite,encourage,teach,tell,want, wait for,wish,would like/love +sb +to do sth...

(2)不带to的不定式作宾补的动词：let/make/hear/see/notice/have/watch. +sb +do sth I noticed someone )(enter)the office last night. 注：省掉o的不定式的句子变被动语态时，需要还原to。 He often makes us )(laugh). We are often made )(laugh).
