求真正英文文法高手15分

１．i had never heard a voice like that in my life
呢句用o既係 past perfect tense，咁只要有 had 同一個動詞o既過去分詞就得。
二樓o既同學仔，應該都好幾用心上課o既，佢記得用呢個 tense 時係有一件較佢遲發生o既往事。但係咁代唔代表一定要o係同一句之中有呢件事並列，等你睇到佢地o既時間關係？
當然係唔駛啦。一個故事之中，成個用 past simple，但當你突然插敍一件往事，咁基準時間就係故事中o既「當時」，而插敍o既事就用 past perfect。隨便用 google 搵 "had never seen"，搵到呢篇文：〔http://ajr.org/article.asp?id=2600〕，第五段就有以下一句：
The World Trade Center, we had never seen anything like this.
作者o既基準時間係九一一發生後，由上文下理可知。
你引出o黎問人o既一句，冇上文下理，唔睇文章其他部份，冇人知係唔係要用 past perfect tense。既然係咁，就冇理由認為你應該轉做 present perfect，更加冇理由要加個 at that moment。
２．but most of the americans still don't know who i am
第一，americans 係講緊所有美國人，yahoo 博士同其他答者都冇睇到應該係用複數。
第二，most 係指「多數」，既然講緊人，就要一個個數，所以 之後o既動詞就要好似跟複數名詞咁，唔應該有 s。
第三，回應一樓：如果 a voice 要註明係 good / bad，咁 He is a boy 呢句係咪都必定要加形容詞？
第四，回應二樓：don't 或 didn't 都冇錯，問題係當時講者意思係乜野。你舉例 I was not listening，自己跟住就將語境講埋出o黎。但 I am not listening 又唔係唔o岩架喎，只係語境唔同之嘛（如以 present continuous 作決定之意）。所以不能武斷用 didn't 較好，都係要睇返原句上文下理。

i Have-caux it never happened before but doesn't means it will never again,off course if u means it never happened before and will not happen in the fure,then u should use Had

Don't caux it's plural

其實上面位朋友或許忽略了一些東西，雖然我們沒有前後文，但發問者卻早已指出：”我明明聽到是ｄｏｅｓｎ’ｔ”，所以，我們可以看到，I have never heard a voice like that in my life並不是從文章來，是從說話來，也因未有說到另一個動作，故參考的時間就是說話者的現在，因此，雖無前後文，但也可知要用

Present perfect tense

1. i had never heard a voice like that in my life

好明顯上面咯個Yahoo 博士係岩既. 用had 的時候的時態一定要是過去的時候先可以用架. 你都冇話係以前既時候, 你點可以用 had 呀. 如果要用 had. 就要是, i had never heard a voice like that until that moment. 而 that moment還要是以前的時候, 再清楚既係. i had never heard a voice like that before i was 10 years old. 一定要係過去的時候先可以用架....還有其實好似用 the voice好d囉不過我都好似見過有d會用 a voice. 意思我相信是更強烈掛. 不過我知都應該係岩既.

2. 我肯定 most of the American still doesn't know who i am 是錯的.
一定是 most of the American still do not know who i am or most of the American still did not know who i am. 因為 most of the American 係複數, 點可以用doesn't 單數既東西呀. 而我自己會選擇用後者 most of the American still did not know who i am. 唔好問點解, 你睇多英文就知道點解架啦. 就好似, i was not listening. 我沒有聽你說的, 為何是過去式, 因為我剛才沒有聽到你在說什麼, 而不是現在.

那麼most of the American still did not know who i am.它們不知道你是誰, 是以前不是現在.

你話你冇聽錯, 咁就一定係佢講錯. 如果咯個係鬼佬, 我都係話佢錯...錯錯錯....

I had never heard a voice like that in my life <--what thing do you say?good voice ? bad voice?

You can say;
I had never heard a good voice in my life until i heard it .[it describes with a good voice]
or
I had never heard a bad voice in my life until i heard it .[it describes with a bad voice]

Most of the american still don't know who i am.




我可能唔岩...Just for sharing.
