在及物动词begin,cease,choose,continue,decide,expect,fail,forget,happen,hate,help,hope,intend,like,love,manage,mean,offer,plan,prefer,prepare,promise,refuse,remember,try,want,wish 等后边常用不定式作宾语.
动词不定式也可作介词but,except,save（除.以外）的宾语,但在词组can not but （不由得,只好）,cannot help but（不得不）,do nothing but（别无它法只有.）后面,接不带 to 的不定式.在except,save 后可带to也可不带 to.
有些动词如allow,advise,ask,beg,believe,can’t bear,call,choose,cause,command,determine,enable,expect,fail,feel,find,force,get,have,hear,help,know,invite,lead,let,like,make,notice,order,prove,request,set,see,teach,tell,think,want,warn,watch,wish等后面常跟动词不定式作宾语补足语.
有些动词如consider,prove,think,know,feel,suppose,discover,imagine,find 等也可跟
“宾语 + to be”的形式,使用中应注意.
学习中要注意积累,我这些仅为参考.加油!
