we could have had it all 的文法?

１．歌詞，詩詞　的語句本來就可以不照文法形式的．為神？很簡單！因為美麗，意境，對稱　在這些地方　比文法正確　要重要多了！難道你不知道語言就是醬子嗎？還是　不考試　掛帥就是不習慣呢？

２．但是很不幸的，這一句話不但美麗，而且文法還超正確的：

他是一句＜與事實不符的敘述句＞
他的意思是＜我等本來是可以擁有一切的＞．因為事實上我等是沒有擁有一切，所以說是與事實不符．
它的結構是：

＜主詞＞＋＜助動詞　　＞＋＜完式　助動詞＞＋＜過去分詞＞＋＜受詞＞＋＜受詞捕魚＞
＜ｗｅ＞＋＜ｃｏｕｌｄ＞＋＜ｈａｖｅ　　＞＋＜ｈａｄ　＞＋＜ｉｔ＞＋＜ａｌｌ　　＞

３．他例：
I could have married him .　　　 = 我本來要嫁給他的．（蛋是沒有）
He could have bought the car.　 = 他本來可以買下那隻車子的．（蛋是沒有）
I could have had burger for lunch = 我本來可以午餐吃肉餅的．（蛋是沒有）

4. 相關變形：

We .................have it all. =　天下都是我們的了．
We ........ have had it all. =　天下已經都是　我們的了！
We could have had it all. = 天下本來可以都是我們的！

＜主詞＞＋＜助動詞　　＞＋＜完式　助動詞＞＋＜過去分詞＞＋＜受詞＞＋＜受詞捕魚＞
＜ｗｅ＞＋＜ｃｏｕｌｄ＞＋＜ｈａｖｅ　　＞＋＜ｈａｄ　＞＋＜ｉｔ＞＋＜ａｌｌ　　＞
為什麼不是>>>>>>>>>>>>>>>>>>>>>>>>>> ＜Ｈａｖｅｎ＞???

［文法］英文中有多種容易混淆的虛擬語氣
could have，would have，should have和must have
1.sb could have done sth 某人本可以做某事（卻沒做）
2.sb would have done sth 某人本來將做某事（卻沒做）
3.sb should have done sth 某人本應該做某事（卻沒做）
4.sb must have done sth 某人應該已經做好某事了
前3種是假設，實際沒做，最後一種是推測

［本句］
①we could have + done 我們本可以
②have it all 擁有一切 have → had
①+②=we could have had it all.
我們本可以擁有一切（卻沒有）。

［例句］
1.She could have become a great singer-songwritter like Adele,but she didn't.
她本可以成為像愛黛兒這樣的創作歌手，但她沒能做成。

2.she would have released her virgin studio album but she chose not to.
她本來將發行她的首張錄音室專輯，但她未選擇這麼做

3.she should have won the award but only earned several mentions
她本應該贏得大獎，但只獲得數項提名

4.she must have got the recording contracts by the independent label.
她應該已經得到獨立廠牌給的唱片合約了
