Re: [文法] 現在完成式：關於明確時間點的定義

[memorabilia (美麗研究所)]

請教一句

I haven't seen him since he left. 這句是OK的

I haven't seen him since he left two years ago. 這句就是技術上不正確嗎？




※ 引述《IOann ()》之銘言：
: http://www.antimoon.com/forum/t16354.htm
: The issue is that "since" is a preposition, and it requires a noun as an
: object, but "two weeks ago" is an adverbial phrase. You can say "I've seen
: you three times since that event two weeks ago", but "I've seen you three
: times since two weeks ago" is technically incorrect.
: 我覺得網頁中的這個說法比較合理。
: 劉毅《文法寶典》P.493 也特別強調 since five months ago 是錯誤的用法。

推 IOann:第二句是錯的。所謂的技術上不正確其實就是文法不對。
推 IOann:since 在這邊是介系詞，它需要接一個名詞。而 two years ago
→ IOann:卻是一串形容詞。
推 IOann:"Use the past tense, not the present perfect, with  ago"
→ IOann:這是前幾篇文章中 longman 字典的解釋。
→ zofloya:你這是自打嘴巴嗎
推 IOann:sorry...第二句是對的，我說錯了。因為 since 後面是一個過
→ IOann:去式的句子。
→ memorabilia:等一下下...我有點搞混,, since 不能和ago 連用,
→ memorabilia:但第二句的since he left two years "ago"就可以是嗎
推 hansi:(x)have + ago
