我們一起來看下面的例子：

　　My teacher gave interesting assignments and motivating the students.

　　很顯然，這屬于混用語法結(jié)構(gòu)的一個典型錯誤。這會使句子產(chǎn)生歧義：難道是說My teacher gave interesting and motivating assignments to the students? 因為本句中 interesting和motivating 是平行結(jié)構(gòu). 或者是My teacher gave interesting assignments and motivated the students? 因為亦可以理解成gave和 motivated是平行結(jié)構(gòu).所以錯誤使用語法會帶來許多意想不到的麻煩。

　　當我們重復(fù)使用一個短語或單詞的時候，不僅會給人以詞匯量過小的感覺，有時甚至也會造成誤解。我們來看一個例子：

　　My teacher wrote the assignment on the chalkboard. The assignment was on the chalkboard until the teacher erased the assignment after we had all done the assignment.事實上這句話的觀點會更加清晰，如果我們將重復(fù)的詞替換為其他表達的話。我們再來看看改進后的表達：

　　My teacher wrote the assignment on the chalkboard. She erased the board after we had all completed the task.

　　其中 assignment 被替換為 task; teacher 變?yōu)榱藄he; chalkboard 被改為了board. 不但句子顯得更加生動活潑不刻板，信息量也比原來要多了。

　　避免托�？谡Z語法的典型錯誤，能夠做到舉一反三，靈活應(yīng)用，相信托�？谡Z考試中的其他問題就能迎刃而解了。小編祝各位學子輕松攻破口語語法!
