Since 引導從句

Yang Li: 大家好歡迎收聽BBC英語教學節目《你問我答》,我是楊莉。這是一個互動的教學欄目,你提問我們解答,通過大量例句來說明英語的使用規則和習慣用法,幫助大家提高進取。本周我選擇的問題來自Lona,請我的同事Finn帶讀。


Question
I'm quite confused about the meaning when the word "since" introduces a clause. What do the following sentences mean?
? I've known her since I've lived here.
? I've known her since I arrived here.
And could you show some more examples for a better understanding? Many thanks!
Yang Li: Lona 提的問題是在since 這個詞引導一個從句的時候,它是什么意思?
我們現在就來看看Lona列舉的兩個句子都是什么意思:
? I've known her since I've lived here.自從我住在這里之后就認識她了。

? I've known her since I arrived here. 自從我到了這兒就認識她了。


Yang Li: 這兩句話里面的since 都是自從的意思。Since是連詞,引導一個時間狀語從句。在漢語里就是從什么時候開始。下面我們再看更多例句:
Examples
We have been friends since we went to school together.
I have been helping Maya ever since she came to study in London.


Yang Li: 第一句話的意思是,自從我們一起開始上學的時候我們就是朋友了。這二句話的意思是,從Maya 來倫敦學習后我就一直在幫助她。

注意在since引導的從句里,動詞必須是過去時:went to school; came to study in London. Let's listen again:
Examples
We have been friends since we went to school together.

I have been helping Maya ever since she came to study in London.

Yang Li: Since 除了可以引導一個從句之外它后面也可以跟一個具體的時間,比如年月日等等:
Examples
We have been friends since 1995.
Jack has not seen his son since last month.
I have been waiting here since 8 o'clock.

Yang Li: 最后我想提示大家since 有兩個主要的意思,除了"自從"這個意思之外,它也可以作為介詞,表示,"由于,因為"。比如:
Example
Since it's the Chinese New Year, let's go to a Chinese restaurant.

Yang Li: 因為是中國的新年咱們還是去一家中餐館吧。
Example
We decided to stay indoors since it was raining.

Yang Li: 由于下雨我們決定呆在家里面。這兩句中的since 都是因為的意思,表示原因。
最后我來揭曉本網頁上的測試題答案:以下幾句話里哪些since 表示時間,哪些表示原因?
? Since it was Sunday, I stayed in bed longer. 因為(reason).
? Since he arrived, everything has been different.自從(time).
? We have been friends since 1995.自從(time).
? We decided to stay indoors since it was raining. 因為(reason).
? I've known her since I arrived here.自從(time).
? Since it's the Chinese New Year I took her to a Chinese restaurant. 因為(reason).
