(不幸福的) important adj.(重要的)—unimportant adj.(不重要的) dis- appear v.(出现)—disappear v.(消失) like v.(喜欢)—dislike v.(不喜欢) order n.(秩序)—disorder n.(紊乱) en- courage adj.(勇气)—encourage v.(鼓励) rich adj.(丰富的)—enrich v.(使丰富) mis- understand v.(理解)—misunderstand v.(误解) 常见后缀见下表： 后缀 例词 -er/-or write v. (写作) —writer n. (作者) act v. (表演) —actor n. (男演员) -ment develop v. (发展) —development n. (发展) -ion/-tion/-ation discuss v. (讨论) —discussion n. (讨论) explain v. (解释) —explanation n. (解释) -ful care n.
