"四個x;一個是x, 一個是x..."的英文表示

這有許多種表示法。最簡潔也最符合現代語法的寫法:
(註:以下都是大致的句型,實際應用會有些變化,詳細可以看下方的例子)

...four something: a, b, c, and d.
...four something; they are a, b, c and d.


以下這些是在Google Books上找來的(當然還有其他寫法,只是Google Books上許多例子無法顯示最後一或兩項,遇到這情況我就沒辦法收錄那些句型...)
(還 有一點就是這些句型只代表有此文字記錄而已,並不代表「一定正確」或是「好」。有空我再問native speakers of English)
1. ...four something.(*1) One is a, another is b, the third is c, and the fourth is d.
2. ...four something. One is a, another is b, one is c, and the last is d.
3. ...four something. One is a, another is b, another is c, and the fourth is d.
4. ...four something. One is a, another is b, another is c, and the last is d.

------
5. ...four something. One is a, the other is b, the other is c, and the fourth (one) is d.
6. ...four something. One is a, the other is b, the third is c, and the fourth is d.


(*1)可以是連接詞,然後把前後子句連在一起。後 面的句子裡的個別子句也可以拆開成獨立句子。詳細的可以看下列的例子。
