prevent to 後接doing

prevent是及物動詞,可是直接帶賓語,表示阻止

例外還有許多短語與doing搭配的，如:keep doing堅持做某事

keep sb.doing使某人一直做某事

practise doing sth.練習做某事

enjoy doing喜歡做某事

finish doing完成做某事

be afraid of doing 害怕做某事

prevent sb (from) doing sth或prevent sb's doing sth。

漢語可說“阻止某人做某事”，但英語習慣上不能說prevent sb to do sth，遇此情況可改說prevent sb (from) doing sth或prevent sb's doing sth。如：

1、我們一定要防止疾病蔓延。

誤：We must prevent the disease to spread.

正：We must prevent the disease (from) spreading.

2、大雨使他不能來。

誤：The rain prevented him to come.

正：The rain prevented his (from) coming.

正：The rain prevented his coming.
