定语从句通常由关系代词that/ which/ who/ whom/ which/ as或关系副词when/ where/ why引导，这些词既指代主句中要说明的名词或代词, 又充当从句中的某个句子成分。

定语从句可分为：限制性定语从句和非限制性定语从句。

定语从句一般都紧跟在它所修饰名词后面，所以如果在名词或代词后面出现一个从句，根据它与前面名词或代词的逻辑关系来判断是否是定语从句。

Unit1 Grammar 同步练习Grammar：句子成分和句子结构一．句子成分句子成分的定义：构成句子的各个部分叫做句子成分。

句子成分有主要成分和次要成分；主要成分有主语和谓语；次要成分有表语、宾语、定语、状语、补足语和同位语。

1. 主语主语是一个句子所叙述的主体，一般位于句首。

但在there be结构、疑问句（当主语不疑问词时）和倒装句中，主语位于谓语、助动词或情态动词后面。

主语可由名词、代词、数词、不定式、动名词、名词化的形容词和主语从句等表示。

指出下列句子中的主语及它的性质：①During the 1990s, American country music has become more and more popular.②often speak English in class.③One-third of the students in this class are girls.④To swim in the river is a great pleasure.⑤Smoking does harm to the health.⑥The rich should help the poor.⑦When we are going to have an English test has not been decided.【答案】①country music （名词）②We （代词）③One-third （数词）④To swim （不定式）⑤Smoking （动名词）⑥The rich （名词化的形容词）⑦When we are going tohave an English test （主语从句）2．谓语谓语说明主语所做的动作或具有的特征和状态。

动词在句中作谓语，一般放在主语之后。

谓语的构成如下：1、简单谓语：由一个动词或动词短语构成。

如：He practices running every morning.2、复合谓语：（1）由情态动词或其他助动词加动词原形构成。
