誤區(qū)三 誤用語(yǔ)言規(guī)則
1. 表示時(shí)間、距離、金錢(qián)、重量、數(shù)量等名詞作主語(yǔ)
?、賂en years are quite a long time. (×)
?、赥en years is quite a long time. (√)
【解析】 表示時(shí)間、距離、金錢(qián)、重量、數(shù)量等名詞的復(fù)數(shù)作主語(yǔ)時(shí)看作一個(gè)整體,謂語(yǔ)動(dòng)詞要用單數(shù),容易錯(cuò)誤理解為復(fù)數(shù)而出現(xiàn)第①句的錯(cuò)誤。
2. 由and連接的并列主語(yǔ)
?、賂he twentieth lesson and last lesson are very easy for students. (×)
?、赥he twentieth lesson and last lesson is very easy for students. (√)
【解析】 the twentieth lesson and last lesson是表示同一概念,譯為“第20課即最后一課”,因此謂語(yǔ)動(dòng)詞應(yīng)該用單數(shù)。同學(xué)們?nèi)菀族e(cuò)誤理解“第20課和最后一課”,如果表示兩課,應(yīng)該表達(dá)為“the twentieth lesson and the last lesson”。
特別提醒 由and連接的并列主語(yǔ)表示同一概念時(shí),謂語(yǔ)動(dòng)詞用單數(shù),表示不同的概念時(shí)謂語(yǔ)動(dòng)詞用復(fù)數(shù)。
3. 就近原則
?、貼either you nor he have been to Beijing. (×)
②Neither you nor he has been to Beijing. (√)
【解析】 neither . . . nor連接的并列主語(yǔ)(you , he)雖然表示兩個(gè)人,但根據(jù)語(yǔ)言規(guī)則,當(dāng)它連接并列主語(yǔ)的時(shí)候,謂語(yǔ)動(dòng)詞根據(jù)就近原則,該由he決定,因此第②句正確。
特別提醒 類(lèi)似的還有either . . . or, not only . . . but also, not . . . but, 以及there be之后的并列主語(yǔ),謂語(yǔ)動(dòng)詞的確定都根據(jù)“就近原則”。
4. this kind of, a piece of, this pair of等短語(yǔ)作主語(yǔ)
?、賂his pair of trousers are very new, but Tom’s trousers are very old. (×)
②This pair of trousers is very new, but Tom’s trousers are very old. (√)
【解析】 trousers作主語(yǔ)時(shí),謂語(yǔ)動(dòng)詞用復(fù)數(shù),但當(dāng)它被this pair of修飾時(shí)謂語(yǔ)動(dòng)詞由pair的單復(fù)數(shù)確定。因此第②句正確。
特別提醒 this kind of, a piece of, a bag of, a box of等,這類(lèi)短語(yǔ)作主語(yǔ)時(shí)謂語(yǔ)動(dòng)詞的單復(fù)數(shù)由這些短語(yǔ)中的名詞決定,而與它們所修飾的名詞無(wú)關(guān)。
5. the rest of,half of等短語(yǔ)作主語(yǔ)
?、貶alf of the students have finished most of the work. The rest of it are very difficult. (×)
?、贖alf of the students have finished most of the work. The rest of it is very difficult. (√)
【解析】 根據(jù)句意和句子結(jié)構(gòu)可以判斷the rest of it中的it,指the work,而work是不可數(shù)名詞,因此第②句正確。
特別提醒 all of, most of, half of, the rest of,以及a lot of, some, any+名詞作主語(yǔ)時(shí),要根據(jù)后面的名詞確定謂語(yǔ)動(dòng)詞的單復(fù)數(shù)。
6. 一句話(huà)提示
?、俸铣刹欢ù~(如something,anybody等)作主語(yǔ),謂語(yǔ)動(dòng)詞用單數(shù);
?、趧?dòng)名詞、不定式、從句作主語(yǔ)時(shí),謂語(yǔ)動(dòng)詞用單數(shù);
?、踑 number of + 名詞(復(fù))作主語(yǔ),謂語(yǔ)用復(fù)數(shù),the number of + 名詞(復(fù))作主語(yǔ),謂語(yǔ)用單數(shù);
?、躰one of . . . 作主語(yǔ)時(shí),謂語(yǔ)動(dòng)詞可用單數(shù),也可用復(fù)數(shù)。
