连系动词是不是就是系动词?

连系动词本身有一定的词义,但不能独立作谓语,必须与表语一起构成谓语。一、 连系动词的类型有：1。"存在"类:表示存在或具有某种特征或状态。这类连系动词强调"存在"。常见的有:be(是),look(看起来),feel(摸上去),seem(似乎是),appear(似乎、显得),prove(证明是),smell(闻起来),taste(尝起来),sound(听起来)等。例如:The story sounds true。Those oranges taste good star。2。"持续"类:表示某种情况或状态的持续。这类连系动词强调"持续"。常见的有:remain(依然),keep(保持),stay(保持),continue(继续、仍旧),stand(处于某状况或情形)等。例如:Why don't you put the meat in the fridge?It will stay fresh for several days。3。"变化"类:表示由一种情况或状态变化成另一种情况或状态。这类连系动词强调"变化"后的情况或状态。常见的有:become(变成),turn(变成),grow(变得),get(变得)等。例如:Put the fish in the fridge,or it will go bad in hot weather。二、注意事项1。有些连系动词通常不用于被动语态和进行时态中。如:feel,taste等词。例如:-Yes,it feels very soft。2。一般情况下,连系动词主要跟形容词或分词作表语。例如:Be careful when you cross this very busy street。If not,you may get run over by a car。3。能跟名词作表语的连系动词常见的有:be,become,appear,seem,prove,remain和turn等。注意:turn后跟(表示主语身份的)名词作表语时,不加冠词。例如:Twenty years later,he turned teacher。The population growth in China remains a problem。4。连系动词也可跟不定式(to do / to be),常见的有:appear,seem,remain,prove,look等。例如:Having a trip abroad is certainly good for the old couple,but it remains to be seen whether they will enjoy it。On the long journey,Peter proved to be a most interesting guide。We all had a wonderful time。表语是用来说明主语的身份、性质、品性、特征和状态的,表语常由名词、形容词、副词、介词短语、不定式、动词的-ing、从句来充当,它常位于连系动词（be,become,appear,seem等）之后。例子:Africa is a big continent。非洲是个大洲。
