高一英語：知識點總結Unit7-8(7)
【考點3】prevent 的用法
▲ 搭配：prevent...from...妨礙;阻礙;防止;預防
▲ 句型：
① prevent sth 阻止……，預防……
② prevent sb's doing sth
③ prevent sb / sth (from) doing sth = stop sb / sth
(from)doing sth = keep sb / sth from doing sth 阻
止/防止某人干……
▲ 注意：在prevent sb / sth from doing sth和stop sb /
sth from doing sth中，from在主動句中可省略，在被動
句中不能省略;keep sb / sth from doing sth 中 from 的
不可省略。
▲ 辨析：prevent; protect
兩詞意義相近，但用法和意思略有差別。protect常用
于protect sb / sth from / against sth 結構中，from或
against 后常接名詞.不接動詞-ing形式。而prevent常
用于prevent sb / sth from doing sth 結構中，而且只能
與from連用，不能與against搭配.from后常接動詞一
ing形式，也可接名詞。例如：
My parents are trying to prevent me from going abroad.
我父母極力阻止我出國。
His advice prevented me from making a serious mis-
take. 他的忠告使我免于犯下嚴重的錯誤。
He raised his arm to protect his face from the blow. 他
伸出胳臂護住臉部免受被拳擊打。
