unit4 TV programmers
before, after, until 都可以用作時(shí)間連詞 ，我們可以用它們來(lái)引導(dǎo)一個(gè)時(shí)間狀語(yǔ)從句，這些連詞可以放在句首，也可以放在句中。放在句首時(shí)，要用逗號(hào)和主句分開(kāi)。
before “比……早一點(diǎn)的時(shí)候”，“在……之前”；
after “比……遲一點(diǎn)的時(shí)候”，“在……之后”。
e.g. before the awards start, we will interview some of the most famous stars.頒獎(jiǎng)活動(dòng)開(kāi)始之前，我們將采訪幾位著名的歌星。
simon went to play basketball after he finished his homework.
until “直到……的時(shí)候”。
e.g. let’s wait until the train stops. 讓我們等火車停下來(lái)吧。
until可以和till互換，但till一般只位于句中，不能位于句首。
e.g. i won’t go to bed until / till those two programmers finish.
not …until… 直到…才…
e.g. you won’t find out the answer until the end of the film.
你要到電影結(jié)束才能發(fā)現(xiàn)答案。
