promote和improve在语意上是有区别的，不容易混淆。

1.promote促进，推进，升职，如：You don't have to sacrifice environmental protection to promote economic growth不必为了促进经济增长而牺牲环境保护。He was promoted last year.他去年升职了。

2. improve提高，改善如：improve my English proficiency，提高我的英语熟练度。Both the texture and condition of your hair should improve你头发的发质与健康状况都应改善。
