past tense 好難

學習英文的tense，要付出努力、時間，不能一步登天。但……不難的，肯學一定學會。

用英文past tense，首先要知道所指的是過去時間所發生的事。其次要能認出屬於past tense的字眼，如

yesterday，the day before yesterday，last week, last year…， ago，this morning之類的字眼。

其次要懂得轉「動詞 verb」變成 past tense (似乎是你的弱點)，但這部分是須打開任何一本較好的英文字典(如牛津高階)，後頁附錄(Appendix)都有一些不規則動詞表(Irregular verbs)，初學者撰一些常用字(如 do . did . done)，背了它已大致可以行走天下，有時間才慢慢精心鑽研其餘部份。

除了這些不規則動詞外，其餘的都是動詞後加ed(如play . played)，或減去y加ied(如study . studied)。

買一本字典，慢慢用心學吧。加油!

前面有past tense後前就不要past tense。例如:He could do up him buttons by himself。但有but、when、and then和so的字眼,後面要就加past tense。例如:I can comb my hair by myself when i was three!
