“get＋賓語＋to do”句型意為“使……去做某事”,其中g(shù)et為使役動詞,不定式作賓語補足語,且to不可少；能用于該結(jié)構(gòu)的使役動詞還有make,let,have,但此時作賓補不定式中的to應省略.例如：
You must get them to come over here．你得想法讓他們到這兒來.
Let them go away．讓他們走開.
find sb doing sth意思是發(fā)現(xiàn)某人正在做某事.
主句的謂語動詞為感官動詞see,hear,watch或find等時,賓語從句常簡化成“感官動詞find＋賓語＋賓語補足語”結(jié)構(gòu),此時賓語由從句的主語轉(zhuǎn)化而來,而賓語補足語多為不帶to的不定式或V-ing形式.如：
I found that some children were playing in the park.→I found some children playing in the park.
