▲辨析：advise；suggest；persuade

三词均表示"建议"，但advise只表示建议，不涉及是否

(one's)doing sth；advise sb that + 主语 + (should) do；

advise sb wh- to do / wh-clause。suggest只表示建议，

不涉及是否成功，常用于下列结构：suggest sth / sb

(that) + (should) do ∥(one's) doing sth ∥ to sb sth

(sth可为that从句)。persuade 劝说成功，常用于下列

结构：persuade sb to do sth (= into doing sth)；per-

suade sb not to do sth(= out of doing sth)；persuade

sb that clause。劝而不服时，采用try to persuade sb to

do sth 结构。例如：

days. 他们建议我们不要在"十·一"长假期间出去旅

游。

carrying it out at once. 他们建议再讨论一下该汁划，但
