托福語法:表示時(shí)間的介詞to,till/until

字號(hào):

to和till/until
    to可以用于時(shí)間和地點(diǎn)之前;till/until只用于時(shí)間之前。可以用from…to或 from…till/until結(jié)構(gòu):
    They worked from five to ten/from five till ten.
    他們從5點(diǎn)工作到10點(diǎn)。(注意勿與at five to ten混淆,后者意為9點(diǎn)55分。)
    但如果句中沒有from,就要用till/until而不用to:
    Let’s start now and work till dark.
    讓我們現(xiàn)在開始工作一直到天黑。(這里不能用to。)
    till/until常常和否定意義的動(dòng)詞連用,以表示強(qiáng)調(diào)時(shí)間晚了:
    We didn’t get home till 2 a.m.
    我們一直到凌晨兩點(diǎn)鐘才到家。
    He usually pays me on Friday but last week he didn’t pay me till the fol-lowing Monday.
    他一般在星期五付給我錢,但上星期他一直到第二周的星期一才把錢給我。
    till/until也常用做時(shí)間連詞:
    We’ll stay here till it stops raining.
    我們將要呆在這里一直到雨停了。
    Go on till you come to the level crossing.
    一直走到火車道口的地方。   注意:如果省略了 you come to,那么就要由 to來代替till:
    Go on to the level crossing.
    一直走到火車道口的地方。
    after, afterwards(副詞)
    after是介詞,后面必須接名詞、代詞或動(dòng)名詞:
    Don’t bathe immediately atrer a meal/after eating.
    不要飯后/吃飯后就游泳。
    Don’t have a meal and bathe immediately after it.
    不要就餐之后立即游泳。   如果我們不想用名詞、代詞或動(dòng)名詞,就不能用after,但可以用 afterwards(= after that)或者 then:
    Don’t have a meal and bathe immediately afterwards.
    (譯文同上)
    They bathed and afterwards played game/played games afterwards./They bathed and then played games.
    他們游了泳,然后做游戲。
    afterwards可以位于句首或句末并且可以由soon,immediate- ly,not long等修飾:
    Soon afterwards we got a letter.
    不久之后我們收到了一封信。
    We got a letter not long afterwards.
    (譯文同上。)   after也可以作連詞用:
    After he had tuned the piano it sounded quite different.
    他給鋼琴校過音之后,鋼琴的聲音完全不同了。
