文章结论:动词"teach"的过去式是"taught",过去分词同样是"taught"。在英语中,teach是一个动词,其基本含义是传授知识或技能,可以指教学、教授,甚至教训他人。作为及物动词,teach可以接名词、代词、动名词或从句作为宾语,也可以接双宾语,还可以接动词不定式或动名词作宾补。例如,"It taught her to ride a bicycle" 表示教某人做某事,"His parents employed a tutor to teach him Greek" 则是说雇佣教师教授课程。过去分词"taught"可以用于被动语态,如"She was taught French by her mother",表示被教。
此外,teach也可用作不及物动词,后接"sb. to do sth."结构,表示使某人学会做某事。例如,"Teach your child to read" 意为教孩子阅读。需要注意的是,teach后的动词不定式有时会用作原因状语,如 "He was taught not to waste time",表示因被教导而避免某种行为。
