謂語動詞指的是在句子中可以單獨作謂語的動詞，主要由實意動詞充當。另外，某些動詞短語也可以是謂語動詞。以下是yjbys爲大家推薦的2017英語六級語法:謂語動詞的重要性，希望對大家有所幫助。
The Greeks assumed that the structure of language had some connection with the process of thought, which took root in Europe long before people realized how diverse languages could be.
首先我們來劃分一下這個句子：
(1)The Greeks assumed that the structure of language had some connection with the process of thought;
(2)the structure of language had some connection with the process of thought;
(3)which (the structure of language had some connection with the process of thought)took root in Europe long;
(4)before people realized(how diverse languages could be) ;
(5)how diverse languages could be;
在五個小句中，各有一個謂語動詞以保證句子的完整度，分別爲：assumed，had，took root in，realized及 could be，如果考生在選取謂語動詞時有困難的話，就會想一下在之前的文章中我們所提到的就如何從複雜的英語句子中去選取謂語動詞;接下來，考生來看一下，既然劃分出五個句子，也就意味着在這個長難句中嵌套了4個從句或小句：
主句的`謂語動詞爲assume，其意思是猜測，在assume後接着一個由that引導的賓語從句;
在assume後的賓語從句中，其謂語從此爲had，意思爲有;
have connection with：與……有關係
(3)逗號隔開的非限制性定語從句中的謂語動詞爲took root in 動詞搭配;
(4)before作爲介詞，經常出現在與時間相關的從句中;(考慮到定語從句中when的使用頻率也較高，故在之後的文章中去區分when在時間狀語從句和定語從句間的區分);
(5)how一詞置於realized之後，作爲賓語從句，且這個句子的謂語動詞爲could be;
句式切分成這樣，考生是不是對句子及意羣間的關係有所瞭解了!那麼接下來，考生可以參看整個句子的句式劃分情況：
主句 The Greeks // assumed // 賓語從句that 從句的主句the structure of / language // had some connection with // the process of / thought, // 定語從句which // took root in Europe // 時間狀語從句long before // people // realized // 賓語從句how diverse // languages // could be.
