可以接带to的动词不定式作宾语的动词主要有:要求选择同意(ask,choose,agree),期望决定学习(expect,hope,decide,learn),宁可假装知道(prefer,pretend,know),希望想要愿意(wish,want,wouldlike/love)
如:1)Wedecidedtotalktosomestudentsaboutwhytheygothere
2)Hepreferstoeatwhitebreadandrice
3)I’dlovetovisitMexico
4)Hepretendedtobehappy

2)Itgivesadviceonwhattodoinlotsofdifferentsituations
3)Wehavedecidedwheretogo
