A tourist visits places for pleasure.印刷工印刷书籍和报纸。发明家发明新事物。游客为了乐趣而游览各地。 这三个后缀加在动词或名词后，构成表示“人”的名词。 -er：最常用，通常直接加在动词后（如 teach → teacher）；以不发音e结尾去e加-er（dance → dancer）；重读闭音节双写末尾辅音加-er（win → winner）。 -or：多用于以-t, -te, -ct, -ss等结尾的动词后（invent → inventor; visit → visitor），部分词属于固定搭配需单独记忆（manager）。 -ist：常加在学科、艺术或乐器类名词后（piano → pianist; science → scientist; art → artist），注意拼写变化（science去e加-ist）。 2.win → winner; dance → dancer; piano → pianist; science → scientist （获胜→获胜者；跳舞→舞者；钢琴→钢琴家；科学→科学家） 添加后缀并非总是直接拼接，需遵循三条核心拼写规则： ① 重读闭音节且末尾只有一个辅音字母时，双写该辅音再加后缀（win-n-er）； ② 以不发音的e结尾时，先去掉e再加后缀（danc-er, scienc-ist）； ③ 以-o结尾的乐器/学科词直接加-ist（pian-ist），但需注意个别例外。掌握这些规则是正确拼写派生词的关键。 Exercise 选择题 Which of the following words is formed correctly with the suffix -er?
