■用法詮釋
連詞是一種虛詞,它不能獨(dú)立充當(dāng)句子成分,而只能連接單詞、短語(yǔ)、句子或者從句,起的是“穿針引線”的作用。
連詞按其性質(zhì)可分為并列連詞和從屬連詞兩大種類?,F(xiàn)結(jié)合2018年各地中考試題,談?wù)勥\(yùn)用連詞時(shí)的易錯(cuò)點(diǎn)。
一、并列連詞
并列連詞用于連接并列的單詞、短語(yǔ)或句子。最常用的并列連詞有“獨(dú)身型”的and、 but、or、so和“伙伴型”的both...and、 either...or、neither ... nor、not only... but also等。其中極易出錯(cuò)的有以下這些:
1.and與but
考查并列連詞的試題常以and、but、so、or作為選項(xiàng)。and通常用于表示對(duì)前面意思的“對(duì)應(yīng)延續(xù)”,而but則表示前面意思的“轉(zhuǎn)折”,因此解題時(shí)必須仔細(xì)推敲前后句意,否則就會(huì)誤選and或but。例如:
我想要買一臺(tái)電腦,可沒(méi)有足夠的錢。
I want to buy a computer, and I don?蒺t have enough money. (×)
I want to buy a computer, but I don?蒺t have enough money. (√)
2.and與or
“祈使句+and+陳述句”與“祈使句+or+陳述句”的用法辨異,是近幾年來(lái)出現(xiàn)最頻繁的連詞考點(diǎn)之一。在這兩種句型中,“and+陳述句”表示前面祈使句的“對(duì)應(yīng)結(jié)果”,而“or+陳述句”則表示前面祈使句的“相反結(jié)果”,即“否則就會(huì)……”。因此解題時(shí),必須依照其中祈使句和陳述句表達(dá)的對(duì)應(yīng)含義來(lái)判斷是填and還是填or。例如:
努力學(xué)習(xí),你會(huì)取得更大的進(jìn)步。
Work harder, or you will make greater progress. (×)
Work harder, and you will make greater progress. (√)
快點(diǎn),否則你會(huì)上學(xué)遲到。
Hurry up, or you will be late for school. (√)
3.so
so連接的句子表示結(jié)果。注意:表示因果關(guān)系時(shí),“一山不容二虎”。即同一句中用了so就不能再用because。同樣,用了because也不能再用so。例如:
因?yàn)樗矚g雞肉,所以她經(jīng)常吃。
Because she likes chicken, so she eats it very often. (×)
Because she likes chicken, she eats it very often. (√)
She likes chicken, so she eats it very often. (√)
4.both...and, either...or, neither...nor, not only ...but also
辨別both...and, either...or, neither...nor和not only ...but also的用法時(shí),我們不但要注意它們自身的含義和句意,還要注意句中謂語(yǔ)的表達(dá)形式。
both...and意為“兩個(gè)都……”,句子的謂語(yǔ)要用復(fù)數(shù)形式。例如:
約翰和彼得正在操場(chǎng)上玩。
Both John and Peter is playing on the playground. (×)
Both John and Peter are playing on the playground. (√)
either...or意為“或者……或者……”,句子的謂語(yǔ)依據(jù)or后面的主語(yǔ)而定。例如:
明天我或者你去那里。
Either you or I are going there tomorrow. (×)
Either you or I am going there tomorrow. (√)
neither...nor...意為“……和……都不”或者“既不……也不……”。通常連接兩個(gè)對(duì)等的成分,用于否定兩者。連接主語(yǔ)時(shí),句中的謂語(yǔ)通常與nor連接的主語(yǔ)保持人稱和數(shù)的一致。例如:
Neither he nor his younger brother is at home today.今天他和他弟弟都不在家。
not only...but also各引導(dǎo)一個(gè)主語(yǔ)時(shí),句子的謂語(yǔ)通常依據(jù)but also后面的主語(yǔ)而定;not only...but also各引導(dǎo)一個(gè)句子時(shí),not only所在的句子要用倒裝語(yǔ)序。例如:
不但學(xué)生而且他們的老師也喜歡那部影片。
Not only the students but also their teacher are enjoying the film. (×)
Not only the students but also their teacher is enjoying the film. (√)
二、從屬連詞
從屬連詞用來(lái)引導(dǎo)名詞性從句和狀語(yǔ)從句。連詞用于引導(dǎo)從句以形成句子的一部分或修飾句子的構(gòu)成要素。
英語(yǔ)的從屬連詞較多,有表示假設(shè)的if和unless,有表示讓步的though和although,有表示原因的because, as, why,有表示時(shí)間的when, while, as, before,
after, since, until, as soon as。另外還有表示目的的so that,表示結(jié)果的so、so that等。
在中考英語(yǔ)試題中,考點(diǎn)主要圍繞表示“假設(shè)、讓步、原因、時(shí)間”的連詞來(lái)設(shè)置,其中極易出錯(cuò)的有以下這些:
1.if與unless
if和unless都可用來(lái)引導(dǎo)條件狀語(yǔ)從句。if表示“如果”,與主句形成“正向假設(shè)”關(guān)系;unless表示“如果不;除非”,相當(dāng)于if not,與主句形成“反向假設(shè)”關(guān)系。解答含if和unless用法的試題,易錯(cuò)點(diǎn)在于能否準(zhǔn)確理解從句與主句之間的邏輯關(guān)系。例如:
如果你不抓緊,就會(huì)錯(cuò)過(guò)最近的火車。
You will miss the last bus if you hurry up. (×)
You will miss the last bus unless you hurry up. (√)
You will miss the last bus if you don?蒺t hurry up. (√)
2.though / although
though / although連接的句子表示讓步概念。漢語(yǔ)中我們可以說(shuō)“雖然……但是……”,但在英語(yǔ)中不行,though / although和but也是“一山不容二虎”。即同一句中用了though / although就不能再用but。同樣,用了but也不能再用though / although。例如:
雖然他退休了,但是他還努力工作。
Though / Although he has been retired, but he still works hard. (×)
Though / Although he has been re+6X/EX9jwTmYgXWO1U+0avboekLU1+/pwOgMgeJPzMM=tired, he still works hard. (√)
He has been retired, but he still works hard. (√) 3.because與 because of
解答考查“原因”的試題時(shí),because的最大干擾項(xiàng)是because of。because屬連詞,引導(dǎo)的是從句,而because of是介詞短語(yǔ),后面接的是短語(yǔ)而不是句子。解答這類題關(guān)鍵是看所接的是句子還是短語(yǔ)。
因?yàn)槟抢餂](méi)有水,所以他非??省?/p>
He was very thirsty because of there was no water there. (×)
He was very thirsty because there was no water there. (√)
4.until與before
在考查until用法的單項(xiàng)選擇題中,常以before作為干擾項(xiàng)。尤其是表示“在……之前”時(shí),考生在until 和before 兩個(gè)選項(xiàng)中極易出錯(cuò)。解答這類試題時(shí),應(yīng)特別注意until的兩種含義:一是until與延續(xù)性或狀態(tài)性動(dòng)詞連用時(shí)表示“直到……”,二是until與瞬間動(dòng)詞連用時(shí)表示“在……之前(不要…… / 沒(méi)有……)”,此時(shí),主句的謂語(yǔ)是否定式或句子含有否定概念。例如:
邁克直到爸爸回來(lái)才去睡覺(jué)。
Mike went to bed until his father came back. (×)
Mike didn?蒺t go to bed until his father came back. (√)
