?用連詞“穿針引線”時的易錯點

■用法詮釋

連詞是一種虛詞，它不能獨立充當句子成分，而只能連接單詞、短語、句子或者從句，起的是“穿針引線”的作用。

連詞按其性質可分為并列連詞和從屬連詞兩大種類。現結合2018年各地中考試題，談談運用連詞時的易錯點。

一、并列連詞

并列連詞用于連接并列的單詞、短語或句子。最常用的并列連詞有“獨身型”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。and通常用于表示對前面意思的“對應延續”，而but則表示前面意思的“轉折”，因此解題時必須仔細推敲前后句意，否則就會誤選and或but。例如：

我想要買一臺電腦，可沒有足夠的錢。

I want to buy a computer，and I don't have enough money.(×)

I want to buy a computer，but I don'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，是近幾年來出現最頻繁的連詞考點之一。在這兩種句型中，“and+陳述句”表示前面祈使句的“對應結果”，而“or+陳述句”則表示前面祈使句的“相反結果”，即“否則就會……”。因此解題時，必須依照其中祈使句和陳述句表達的對應含義來判斷是填and還是填or。例如：努力學習，你會取得更大的進步。

Work harder，or you will make greater progress.(×)

Work harder，and you willmake greater progress.(√)

快點，否則你會上學遲到。

Hurry up，or you will be late for school.(√)

3.so

so連接的句子表示結果。注意：表示因果關系時，“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：

因為她喜歡雞肉，所以她經常吃。

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，我們不但要注意它們自身的含義和句意，還要注意句中謂語的表達形式。

◆both...and意為“兩個都……”，句子的謂語要用復數形式。例如：

約翰和彼得正在操場上玩。

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……”，句子的謂語依據or后面的主語而定。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……”。通常連接兩個對等的成分，用于否定兩者。連接主語時，句中的謂語通常與nor連接的主語保持人稱和數的一致。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各引導一個主語時，句子的謂語通常依據but also后面的主語而定；not only...but also各引導一個句子時，not only所在的句子要用倒裝語序。例如：

不但學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

從屬連詞用來引導名詞性從句和狀語從句。連詞用于引導從句以形成句子的一部分或修飾句子的構成要素。

英語的從屬連詞較多，有表示假設的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，表示結果的so、so that等。

在中考英語試題中，考點主要圍繞表示“假設、讓步、原因、時間”的連詞來設置，其中極易出錯的有以下這些：

1.if與unless

if和unless都可用來引導條件狀語從句。if表示“如果”，與主句形成“正向假設”關系；unless表示“如果不；除非”，相當于if not，與主句形成“反向假設”關系。解答含if和unless用法的試題，易錯點在于能否準確理解從句與主句之間的邏輯關系。例如：

如果你不抓緊，就會錯過最近的火車。

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't hurry up.(√)

2.though/although

though/although連接的句子表示讓步概念。漢語中我們可以說“雖然……但是……”，但在英語中不行，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 retired，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，because的最大干擾項是because of。because屬連詞，引導的是從句，而because of是介詞短語，后面接的是短語而不是句子。解答這類題關鍵是看所接的是句子還是短語。

因為那里沒有水，所以他非常渴。

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用法的單項選擇題中，常以before作為干擾項。尤其是表示“在……之前”時，考生在until和before兩個選項中極易出錯。解答這類試題時，應特別注意until的兩種含義：一是until與延續性或狀態性動詞連用時表示“直到……”，二是until與瞬間動詞連用時表示“在……之前（不要…… /沒有……）”，此時，主句的謂語是否定式或句子含有否定概念。例如：

邁克直到爸爸回來才去睡覺。

Mike went to bed until his father came back.(×)

Mike didn't go to bed until his father came back.(√)
