初中系动词总复习定义系动词亦称连系动词（Link Verb），作为系动词，它本身有词义，但不能单独用作谓语，后边必须跟表语（亦称补语）（形容词），构成系表结构说明主语的状况、性质、特征等情况。
说明：有些系动词又是实义动词，该动词表达实义时，有词义，可单独作谓语，例如：He feels ill yesterday.他昨天病了。
（feel是系动词，后跟补足语，说明主语情况。
）]分类1）状态系动词用来表示主语性质或状态，只有be一词，例如：He is a teacher. 他是一名教师。
（表示主语的身份－－性质）He is ill. 他病了。
（表示主语的状态）2）持续系动词用来表示主语继续或保持一种状况或态度，主要有keep, rest,remain, stay, lie, stand, 例如：He always kept silent at meeting. 他开会时总保持沉默。
This matter rests a mystery. 此事仍是一个谜。
3）表像系动词用来表示"看起来像"这一概念，主要有seem, appear, look, 例如：He looks tired. 他看起来很累。
He seems (to be) very sad. 他看起来很伤心。
4）感官系动词感官系动词主要有feel, smell, sound, taste, 例如：This kind of cloth feels very soft.这种布手感很软。
This flower smells very sweet.这朵花闻起来很香。
5）变化系动词这些系动词表示主语变成什么样，变化系动词主要有become, grow, t urn, fall, get, go, come, run.例如：He became mad after that. 自那之后，他疯了。
She grew rich within a short time. 她没多长时间就富了。
6）终止系动词表示主语已终止动作，主要有prove, turn out, 表达"证实"，"变成"之意，例如：The rumor proved false. 这谣言证实有假。
The search proved difficult. 搜查证实很难。
His plan turned out a success. 他的计划终于成功了。
（turn out 表终止性结果）]注意事项系动词本身有一定的词义，不能单独作谓语，后面必须与表语连用。
复习系动词时，必须注意以下几个问题：1. be是最重要的系动词，主语不同，be的形式也不同，且有时态的变化。
通常表示主语的特征、状态和身份等，后面接形容词、副词、名词、介词短语、不定式、v-ing、过去分词及表语从句作表语。
特别要注意“由be+过去分词”所构成的系表结构与“由be+过去分词”所构成的被动语态的区别。
前者侧重于表示主语的特征或所处的状态，通常没有由by引导的介词短语。
如：The door was closed.后者侧重于强调主语是谓语动词所示动作的承受者，表示动作；句中可以用由by引导的介词短语。
如：The door was closed by me.还要注意“由be+ V-ing所构成的系表结构与“由be+ V-ing”所构成的进行时态的区别。
前者侧重于说明主语具有的特征或存在的状态，也可说明主语是什么。
如：My job is teaching English.后者侧重于强调主语正在做某事。
如：Mr Wang is reading an evenin g paper now.2. 要注意由行为动词转化成的系动词。
表示人体感官的系动词有sound，taste，look，feel，smell等，后面接形容词；表示主语从一种状态转变到另一种状态的系动词有become，get，go，t urn，run，grow，come，fall，prove等，后面接形容词、名词或 to be+形容词，become后面接单数名词时，名词前要用不定冠词，turn后面接单数名词时，名词前不用不定冠词；表示主语继续或保持某种身份、特征或状态的系动词有continue，kee p，remain，stay，stand lie，rest，stay等，后面接表示状态的形容词；表示判断的系动词有seem和appear，后面接形容词、to be+名词或形容词、that-clause、不定式等。
3. 要注意系动词的固定搭配。
常见的有come true, fall asleep, fa ll ill, go bad, come right, run wild, wear thin, turn nasty等。
4. 要特别注意某些动词既可以做系动词，又可以做实意动词的用法。
系动词部分主要注意：其后要求接形容词，而不是副词做表语。
遇到这种情况，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做出正确判断和选择。
以taste一词为例：The newly-invented soft drinking tastes quite unique.（这种新研制的软饮料尝起来挺独特的。
注意：在这句话里，taste做系动词，不能使用进行时，后面接形容词。
）The chef is tasting the fish carefully.（厨师长正在品尝这道鱼。
注意：在这句话中，taste做实意动词，可以使用进行时，并且后面接副词做状语。

最常用的连系动词为be（是）动词，即完全连系动词，另外还有look，turn，feel，get，become，sound，smell，stand，go，remain等半连系动词。
无论是完全连系动词还是半连系动词、后面都有表语。
由于半连系动词是由实意动词变来的，那如何分辨该动词为实意动词还是半连系动词呢？这对初学英语的中学生来说会感到有点困难，我在教学中尝试用比较法和替换法，使学生较能接受。
1．比较法比较下列各组句子(1) A． Please look at the blackboard．请看黑板。
B． He looked a perfect fool．他看上去是个十足的傻瓜。
(2) A．Turn to Page 16．翻到 16页。
B．He turned traitor to his country．他背叛了祖国。
A．He felt it his duty to help others．他认为帮助别人是自己的责任。
B．I felt very hungry after a long walk．走了一段长路，我感到很饿。
