SAT語法考點之流水句.

　　在SAT語法題中，流水句的問題非常難以辨別。因為流水句是漢語中特有的一類復(fù)合句，漢語句子的信息容量沒有語法形式上的限制，彈性很大，一句接著一句。只需要用逗號連接，恰似流水，可以無限制地擴展下去。但英語句子有各種語法形式要求，不接受這種表達方式。因此受漢語的影響，類似的逗號使用錯誤和無標(biāo)點句是中國學(xué)生英語寫作中普遍出現(xiàn)的問題。以下是流水句的主要考試形式：

　　流水句考點小結(jié)

　　→流水句的典型結(jié)構(gòu)：SVO, (adv.) SVO.

　　→流水句的變形結(jié)構(gòu)：SVO, VO.

　　一、考點詳解

　　1. 流水句的典型結(jié)構(gòu)：SVO, (adv.) SVO.

　　簡單來講，流水句就是錯誤地將兩個獨立分句合寫在一個句子里面，沒有正確地用標(biāo)點或連詞加以分離。流水句本質(zhì)上體現(xiàn)了英語中連詞與分句的數(shù)量關(guān)系要求：即兩個分句有且只有一個連詞，三個分句有且只有兩個連詞，以此類推。只要把握住該原則，流水句的問題就不難被發(fā)現(xiàn)。

　　閱讀以下例句，找出其中語法錯誤。

　　例句1：Many students fool around after school and on weekends, consequently they do not have much time for doing their homework.

　　例句1是由兩個分句構(gòu)成：第一個分句為Many students fool around after school and on weekends, 第二個分句為consequently they do not have much time for doing their homework. 兩個分句之間沒有任何連詞，而使用逗號是不可以連接兩個分句的。

　　閱讀以下例句，找出其中語法錯誤。

　　例句2：My grandfather never learned to use a calculator, as he shops he can accurately compute his grocery bill in his head to within a dollar.

　　例句2是由三個分句構(gòu)成：第一個分句為My grandfather never learned to use a calculator, 第二個分句為he shops, 第三個分句為he can accurately compute his grocery bill in his head to within a dollar. 而連接三個分句中只有一個連詞as，不符合連詞與分句的數(shù)量關(guān)系要求。

　　2. 流水句的變形結(jié)構(gòu)：SVO, VO.

　　以上兩個流水句的形式用句子結(jié)構(gòu)分析方法可以抽象為SVO, (adv.) SVO(例句1); SVO, conj. SVO SVO.(例句2)，這類句子都是典型的流水句結(jié)構(gòu)。除了上述流水句結(jié)構(gòu)之外，還會出現(xiàn)下面這種變形情況。

　　閱讀以下例句，找出其中語法錯誤。

　　例句3：The beaver is the largest rodent in North America, has a large, flat, nearly hairless tail, webbed hind feet, and short front legs with hairy claws.

　　例句3是由一個完整分句The beaver is the largest rodent in North America, 一個不完整分句(缺少主語)large, flat, nearly hairless tail, webbed hind feet, and short front legs with hairy claws構(gòu)成，即SVO, VO.結(jié)構(gòu)，該結(jié)構(gòu)依然是流水句。

　　在SAT語法考題中，處理流水句，一般會采取以下幾種方法：

　?、俣禾栕?yōu)榫涮?，兩分句獨立成完整的句子?/p>

　?、诙禾柡笥貌⒘羞B詞連接兩分句

　?、圩兌禾枮榉痔?可以使用連接副詞體現(xiàn)邏輯關(guān)系，如：therore, thus, however furthermore, nevertheless)

　?、苤饕志渥髦骶?，其它分句變成從屬結(jié)構(gòu)(從句或詞組，強調(diào)主句所表達的意義，弱化從屬結(jié)構(gòu)所表達的意義)

　　二、真題再現(xiàn)

　　1. The beaver is the largest rodent in North America, it has a large, flat, nearly hairless tail, webbed hind feet, and short front legs with hairy claws.

　　A) The beaver is the largest rodent in North America, it

　　三、難點講解

　　流水句的難點在于連接副詞和連詞的區(qū)別：在英語中，有很多連接副詞，如however, therore，它們只能在意義和邏輯上連接兩個分句，而不能在語法上連接分句，所以需要對容易混淆的連接副詞和連詞重點掌握。
