(2) suggestion 的搭配有：make a helpful / timely suggestion 作出有益（適時）的建議。act on / at one\'s suggestion = act on / at the suggestion of sb 按照某人的建議做。
(3) suggestion , advice 和 opinion
advice 多指根據自己的學識和經驗提出來的供人參考的意見。suggestion 指為改進工作、解決問題而提出的建議，比 advice 委婉。opinion 是日常用語，指對某事的觀點、想法。另外，advice 是不可數名詞。
advice is seldom welcome . (諺語) 忠言逆耳。
