用法辨析
- prevent的基本意思是“止”,可表示“阻止”(某計(jì)劃或意圖)、“防止”(已有兆頭的險(xiǎn)事、惡事)、“制止”(某人做某事)等,強(qiáng)調(diào)做好預(yù)先的防備或準(zhǔn)備,含有“阻止成功”的意味。
- prevent主要用作及物動(dòng)詞,可接名詞、代詞或動(dòng)名詞作賓語(yǔ),不接不定式作賓語(yǔ)。用作prevent賓語(yǔ)的動(dòng)名詞前常有物主代詞或者名詞,人稱代詞賓格表示其邏輯主體。prevent可用于被動(dòng)結(jié)構(gòu)。prevent偶爾也可用作不及物動(dòng)詞。
- 表示“阻止做某事”,可用prevent sb/sb's v -ing,也可用prevent sb from v -ing,這幾種用法在意義上沒(méi)有明顯的區(qū)別。
- prevent指“阻止成功”,如果阻止了,但是沒(méi)有成功,不可用prevent。如果說(shuō)她阻止他去,實(shí)際上他的確沒(méi)有去,可以說(shuō)She prevented him from going.但是他不聽(tīng)勸,還是去的話,要說(shuō)She tried to prevent him from going, but he still went;
- prevent加賓語(yǔ)時(shí),賓語(yǔ)后不可接不定式。She prevented him to go. 該句是錯(cuò)誤的表達(dá)。
v. (動(dòng)詞)
英漢例句
- We shall come tomorrow if nothing prevents.
如沒(méi)有什么阻礙的話,我們明天來(lái)。 - Business has prevented me.
