系动词又称连系动词，不单独作谓语，必须与表语连用构成系表结构。系表结构可表述主语的状况，而我们对主语情况的了解和描述角度各不相同，因此对主语的表述就因说话人的角度不同，而使用不同的系动词。现就初中课本中的系动词小结如下：
1、 以肯定的语气叙述主语状态时，要用系动词be，后接n（名词）,adj（形容词）,p.p（分词）,inf（不定式）， adv（副词） ,prep. Phr.（介词短语）作表语。
如：（1）He is honest.
(2) She is a teacher.
(3) The film is moving.
(4) He is out.
2、表示说话人所感知的主语的特征或状态时，系动词用look, feel, sound, taste, smell等，后常接n（名词）,inf（不定式）,p.p（分词）,adj（形容词）等作表语。
如：（1）Her voice sounds sweet.
(2) It sounds a good idea.
(3) It looks the right thing for her birthday gift.
3、表示主语状态变化时，系动词用become ,get, grow, come , turn (若跟名词不加冠词) ，fall (asleep, ill, silent)等，后面大多数接形容词作表语。但become, turn亦可接名词作表语。
如：（1） He turns doctor.
(2) He becomes a doctor.
(3) My dream has come true.
(4) The baby fell asleep.
(5) The leaves turned yellow.
4、表示主语的持续时，系动词用remain, stay , keep, continue等。
如：(1) The door keeps open.
(2) The problem remains unsolved.
5、从印象的角度说明主语所处的状态和特征时，系动词用appear to be (常用于书面)，seem (to be)。
如：（1）You don’t seem to be quite yourself today.
(2) You seem right.
(3) It seems as if it’s going to snow.
系动词的使用应注意如下：
1、 其后要求接形容词，而不是副词作表语。要特别注意的是有些动词既可以作系动词，又可作实意动词的用法。遇到这种情况时，只能先根据其意思判断清楚到底是前者还是后者，然后再对后面的词性和词义作出判断和选择。以taste一词为例：
The soft drinking tastes quite sour.(注意：在这里，taste作系动词，不能使用进行时，后面接形容词。)
The chef is tasting the fish carefully.(注意：在这里，taste作实意动词，使用进行时，并且后面接副词做状语。)
2、 这类词不用进行时。
3、系动词无被动式。
