Topic 77: perfect tense 六種轉換法

上一講說過，不規則動詞（irregular verbs) 轉過去分詞 (past participle) 有六種方法：

Method 1: i -> a -> u 🧐
E.g. swim - swam - swum
Method 2: present form + -n/en/ne 🧐
E.g. give - gave - given
Method 3: past form + -n/en/ne 🧐
E.g. tear - tore - torn
Method 4: same as the past form 🧐
E.g. buy - bought - bought
Method 5: unchanged 🧐
E.g. hit - hit - hit
Method 6: special cases* 🧐🧐

所謂特殊例子 (special cases)，就是指不適用於上述任何一個方法，小學生常用的有附圖幾個。只要掌握了這六大方法，小朋友或會發現，原來學perfect tense 又不是太難了！💪💪
