為什麼這篇would could should意思鄉民發文收入到精華區：因為在would could should意思這個討論話題中，有許多相關的文章在討論，這篇最有參考價值！作者enterobacter (only one)看板Eng-Class標題Re: [文法] 請問如...
※ 引述《tonyxie (123)》之銘言：
: 請問如何區分，使用以上的助動詞 ?
: 像是will/would 常搞不清楚
: 例如: 離婚將會影響小孩的發展
: 該寫: Divorce will affect Children's development.
: 或 : Divorce would affect Children's development.
: 請教各位高手，謝謝
應該是用will.......畢竟這是一個未來可能會發生的事情!!
首先我們分成兩個層面探討助動詞,一個層面是基本用法
另外一個層面是慣用語法(這部分 有空我會PO上來)
~~~~~~~~~~~~~~~~~~~~~表格分隔線~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
will would
1. 表示未來式 will的過去式
ex:I said I would do it.
(因為前面動詞以表過去 後面應該用過去式would)
2. 打算;想
ex: I won't make the same mistake again.
3. 有~的習慣 表示過去的習慣
ex : He will often stay up ex: He would often get up early.
all night.
4. 請你......好嗎?? 表示客氣的請求
ex:Would you come in???
(請進好嗎??)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
can的用法:
1.表示能力: ex: He can swim = He is able to swim
PS:在此特別強調 並不是所有的can都可替換成be able to
ex: The book is able to be finish in an hour.........(X)
^^^^^^^^
關鍵在於be able to 的適用對象是"人"或"動物"
2.表示強烈懷疑: ex: Can it be true??? 中文翻成可能....的嗎???
3.用於否定推測:can't ,對於過去否定的推測(即表示當時不可能怎樣....)
cannot have + p.p
ex: He cannot have said so. (他是不可能這樣說的)
4.表示客氣的請求: Could
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
另外一提的是should/ought to
1.當作應該的意思, ought to (should)+ 原形動詞
2.若ought to (should)+完成式,即表示當時應該怎麼作 ,但是"沒有做"
ex: He ought to have come yesterday, but he didn't.
(他昨天應該要來的,可是他並沒有來)
3.ought to 表否定時的位置: ought "not" to +原形動詞
ex: You ought not to be cruel to animals.(你不應該虐待動物)
4.ought to表疑問時: ought + 主詞 + to +原形動詞
ex: Ought I to go??(我應該去嗎??)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
呼........很長喔!!看起來眼睛酸了沒.....該休息一下了^___^
