當(dāng)數(shù)量概念作主語(yǔ)時(shí)主語(yǔ)一致的用法 1. 表時(shí)間長(zhǎng)度、錢數(shù)、速度等的詞組作主語(yǔ)時(shí),通常將其視為整體,謂語(yǔ)動(dòng)詞用單數(shù)。如: Twenty years is a long time. 20年是很長(zhǎng)的時(shí)間。 Ten dollars is all I have left. 我只剩下10美元。 2. “分?jǐn)?shù)(百分?jǐn)?shù))+of+名詞”結(jié)構(gòu)作主語(yǔ)時(shí),謂語(yǔ)動(dòng)詞的數(shù)與其中名詞的數(shù)保持一致。如: About 20 percent of the pupils were absent that day. 那天大約有20%的學(xué)生未到。 Three-fourths of the surface of the earth is covered by sea. 地球表面的四分之三是海。 注:在現(xiàn)代英語(yǔ)中,有時(shí)即使該結(jié)構(gòu)中的名詞為復(fù)數(shù),其謂語(yǔ)也可用單數(shù)(即將其視為整體)。如: Over eighty per cent of families own [owns] a television. 百分之八十以上的家庭已擁有電視機(jī)。 3.“one in [out of]+復(fù)數(shù)名詞”作主語(yǔ)時(shí),謂語(yǔ)動(dòng)詞通常用單數(shù)。如: Only one in ten students has passed the examination. 只有十分之一的學(xué)生通過(guò)了考試。 One out of twelve bottles was broken. 每12個(gè)瓶子中有一個(gè)破了。 注:在非正式文體中有時(shí)也用復(fù)數(shù)謂語(yǔ)。如: Nationwide, one in five adults are illiterate. 就全國(guó)范圍而言,五個(gè)成年人中有一個(gè)是文盲。 4. “all of (some of, none of, half of, most of, lots of, plenty of)+名詞”作主語(yǔ)時(shí),謂語(yǔ)動(dòng)詞的數(shù)與其中名詞的數(shù)保持一致。如: Half of the apple is bad. 這個(gè)蘋果有一半是壞的。 Half of the apples are bad. 這些蘋果當(dāng)中有一半是壞的。 Half of our money goes on food. 我們有一半的錢花在食物上。 5.“one and a half+復(fù)數(shù)名詞”與“a+單數(shù)名詞+and a half”作主語(yǔ)時(shí),國(guó)內(nèi)不少書(shū)認(rèn)為,這兩個(gè)結(jié)構(gòu)作主語(yǔ),謂語(yǔ)均用單數(shù)。如: One and a half months has passed. / A month and a half has passed. 已經(jīng)過(guò)去了一個(gè)半月。 但是,國(guó)外一些詞書(shū)則認(rèn)為,謂語(yǔ)動(dòng)詞的數(shù)取決于這兩個(gè)結(jié)構(gòu)中名詞的數(shù)。如: One and a half months have passed. / A month and a half has passed. 已經(jīng)過(guò)去了一個(gè)半月。 6.“the [a] number of+名詞”作主語(yǔ)時(shí),該結(jié)構(gòu)若用定冠詞,其后謂語(yǔ)用單數(shù);若用不定冠詞,其后謂語(yǔ)用復(fù)數(shù)。如: The number of people invited was fifty, but a number of them were absent for different reasons. 有50人被邀請(qǐng)參加,但是很多人因?yàn)楦鞣N原因而缺席。 |
