dissuade

1.dissuade（劝阻）后面现在接宾语和from，不接宾语和不定式，如I must dissuade you from your purpose和I must dissuade you from going。from going不可改作to go。

2.dissuade可能是“劝阻成功”，可能是“劝阻（而未必成功）”，通常必须看了上下文才能看出。例如：

• He dissuaded me from my purpose, without much difficulty. （成功）
• He dissuaded me from my purpose, but did not insist. （不成功）
• 用在被动语态总是指成功的。例如：I am thankful that I was dissuaded from my purpose.
