英语可说prevent sb to do sth吗汉语可说“阻止某人做某事”，但英语习惯上不能说 prevent sb to do sth，遇此情况可改说 prevent sb (from) doing sth或prevent sb’s doing sth。如：■我们一定要防止疾病蔓延。误：We must prevent the disease to spread.正：We must prevent the disease (from) spreading.■大雨使他不能来。误：The rain prevented him to come. 正：The rain prevented his (from) coming. 正：The rain prevented his coming.
