until 作介詞
作介詞的until 的英文解釋是up to a specified time (直到某一時(shí)刻)或up to the time of a specified event (直到發(fā)生某事).但注意觀察下列句子,我們還可留意到until 在具體運(yùn)用中的細(xì)微之處.
1. 用于肯定句中：
1) It may last until Friday. 這可能要延續(xù)到星期五.
2) He will be working until 5 o'clock. 他將一直工作到五點(diǎn)鐘.
3) She was a bank clerk until the war, when she trained as a nurse. 她戰(zhàn)前是個(gè)銀行職員,戰(zhàn)時(shí)受訓(xùn)當(dāng)了護(hù)士.
不難看出until 用于肯定句中,表示句子的動(dòng)作一直持續(xù)到until短語所表示的時(shí)間為止,即表示動(dòng)作的終點(diǎn).一般可譯為“直到……時(shí)(為止)”或“在……以前”.在這種用法中,句子的謂語動(dòng)詞必須是持續(xù)動(dòng)詞(非瞬間動(dòng)詞),如live, wait , last, love, like, stay, work, continue 等.
2. 用于否定句中：
1) The secret was never told until after the old man's death. 這個(gè)秘密在老人去世后才說出來.
2) Don't open it until your birthday. 等到你過生日那天再打開.
3) She didn't sleep until eight. 她八點(diǎn)鐘才睡覺.
不難看出until用于否定句中,表示句子的動(dòng)作直到until短語所表示的時(shí)間才開始發(fā)生,即表示動(dòng)作的起點(diǎn).一般譯為“直到……才”或“直到……之前(……還不)” .
until作連詞
以同樣的方式分析作連詞的until的用法.作連詞用的until的英文釋義是up to the time when(直到……時(shí)為止).
1. 用于肯定句中：
1) Heat can be conducted from a hot body to a cooler one until both are at the same temperature.熱可以從一個(gè)熱的物體傳到一個(gè)較冷的物體,直到兩者溫度相同為止.
2) Continue in this direction until you see a sign. 一直朝著這個(gè)方向走就會(huì)看見指示牌了.
3) He ran until he was breathless. 他一直跑到氣喘吁吁才停下.
不難看出,作連詞的until用于肯定句中,表示主句的動(dòng)作一直持續(xù)到從句動(dòng)作發(fā)生或狀態(tài)出現(xiàn)時(shí)為止.一般可譯為“……直到……為止”.在這種用法中,主句的謂語動(dòng)詞必須是持續(xù)動(dòng)詞(非瞬間動(dòng)詞),如live, wait , last, love, like, stay, work, continue 等.
2. 用于否定句中：
1) I hadn't realized she was foreign until she spoke. 她不說話我還一直不知道她是個(gè)外國人.
2) I won't stop shouting until you let me go. 你不放我,我就一直喊叫.
3) Among the great mathematicians there are about as many who showed mathematical talents in childhood as there are those who showed none at all until they are older. 在偉大的數(shù)學(xué)家中,童年就顯露數(shù)學(xué)才華的人和直到相當(dāng)年齡才顯露才華的人差不多一樣多.
不難看出,作連詞的until用于否定句中,表示主句的動(dòng)作在從句的動(dòng)作發(fā)生之前尚未發(fā)生,或者說主句的動(dòng)作在從句的動(dòng)作發(fā)生之后才開始.一般可譯為“直到……才”.
