一、關於since，你應該知道的用法有

adv.

此後；後來

約6,000 人被捕，後來其中的幾百人又被釋放了。

conj.

1.從...以後；自...以來

自打出生，我就住在這兒。

2.因爲；由於；既然

prep.

自...以後；從...以來

幾年前她得了神經衰弱，自那以後就變得十分靦腆。

二、詞義辨析：哪些詞彙能表示原因

as, because, for, since

這些連詞均含有“因爲”之意。

as從屬連詞，語意較because, since弱，着重在主句，所表示的原因或理由是“附帶的”。

because從屬連詞，語意強，着重直接的原因或理由，所引出的從句是全句的重心，用以回答why提出的問題。

for並列連詞，語氣較弱，所引出的句子一般放在後面，表示附帶說明的理由或推斷理由。

since語意比because弱，但比as強，一般用於表示“由於大家已知的事實”。

三、最後，做個填詞遊戲吧

It's twenty years ______ I've seen her.
我已經二十年沒見她了。
