定語從句和非謂語動詞一直是SAT/ACT語法，甚至是理解閱讀文章中長難句的重點，也是困擾很多考生的難點之一。下面是小編收集整理的定語從句和非謂語動詞的相關內容，希望對您有所幫助!
定語從句和非謂語動詞解析：
熟悉非謂語動詞的同學們應該都知道，非謂語動詞包括to do, doing和done，這三類動詞的特別之處就在於它們可以在句子裡面充當除謂語以外的任何成分，其中一個非常重要的用法就是位於名詞後作為名詞的後置定語，比如：
The semiarid lands bordering the deserts exist in a delicate ecological balance and are limited in their potential to adjust to increased environmental pressures.
以上例句裡的非謂語動詞的短語“bordering the deserts”就是用作定語來修飾前面的`名詞短語“the semiarid lands”。
很多同學很熟悉定語從句，而對非謂語動詞的用法總是有種望而卻步的感覺。
但是細心的同學肯定會發現，其實在語法家族裡，當將非謂語動詞用作後置定語的時候，它與定語從句的用法是一樣的，兩者是名副其實地長相不同，但卻有血緣關係的“遠房表親”。比如，上面的例子我們就可以改寫成定語從句：
The semiarid lands which border the deserts exist in a delicate ecological balance and are limited in their potential to adjust to increased environmental pressures.
再如以下帶有非謂語動詞短語的句子：
Theorist adopting the psychodynamic approach hold that inner conflicts are crucial for understand human behavior, including aggression.
我們可以改成定語從句：
Theorist who adopt the psychodynamic approach hold that inner conflicts are crucial for understand human behavior, including aggression.
又如，以下的兩個句子的意思是相同的：
audience came to see was the magic made possible by trick photography and manipulation of the cinema.
audience came to see was the magic that was made possible by trick photography and manipulation of the cinema.
在很多情況下，學生更容易理解定語從句。所以，下次在處理包含非謂語動詞短語的長難句時，不妨將其改寫成定語從句，方便我們理解長難句。
那麼問題來了，定語從句和作定語的非謂語動詞之前是否有某種特定的對應關係呢?答案是有的，關係如下：
Which be to do = to do(表主動/將來)
Which do... = doing...(表主動)
Which be done... = done...(表被動)
為方便大家記憶，哈耶普的老師為大家準備了一個“玫瑰凋謝理論”：
roses to be planted in the garden are fading away.
roses which are to be planted in the garden are fading away.
roses growing in the garden are fading away.
roses which grow in the garden are fading away
roses planted in the garden are fading away.
roses which are planted in the garden are fading away
