英文過去式的用法

Question

wasn't, weren't, didn't 這三個都是過去式，但是wasn't / weren't 與 didn't 怎區別？我常常搞混了他們的用法捏！能不能提供一個清楚且易懂的理解方式呢？感激不盡！

Answer 1

wasn't = was not
weren't = were not

給個表:
現在式 --> 過去式
am --> was
is --> was
are --> were
前兩個是配合單數
後者是配合複數
而這些都是be動詞的變化
後面常接名詞,形容詞,界係詞等
最簡單的意思會像是: 過去/之前/從前不是怎樣的
例句:
I wasn't fat. 我過去不胖
He wasn't a teacher. 他之前不是個老師
You wrern't at home. 你之前不在家.

didn't = did not

did是助動詞 所以後面一定有一般動詞(像是eat, run, fly...等)
助動詞幫助一般動詞形成過去式.
例句:
I didn't eat anything. 我啥都沒吃
He didn't go to school. 他沒上學
You didn't like her. 你不喜歡她

基本上你會be動詞和助動詞 這些就會了

阿 上面例句打錯 sorry
應該是 You weren't at home.

另,一個句子怎會沒有動詞?!?!?!?!?!?!?!

be動詞就是動詞 因為他有時態
助動詞後接原形動詞, 所謂原形動詞就是沒有時態的

Answer 2

千萬千萬要記得!!!
wasn't 和 weren't 是用在沒有動詞的句子上，而且是用在過去否定喔!!
舉例: He wasn't a farmer before . (他以前不是個農夫。)
They weren't happy last Friday . (他們上禮拜五很不開心。)
以上兩個句子皆沒有動詞，所以要用wasn't OR weren't !!!
而didn't 是 don't 和 doesn't 的過去式。只要在過去簡單式看到有動詞，那就要用didn't 囉!!(記得did 是助動詞，所以要加原形動詞喔!!)
舉例: I didn't take any pictures in America . (我在美國沒有拍任何一張照片。)
這樣會了嗎??
有問題再問吧!!
