be是英语动词中比较特殊的一类动词,其使用频率很高,牵涉到各种句型、时态和语态等用法,今天就跟大家分享一下be动词的各类用法。
系动词be作为系动词(也叫连系动词,link verb)的be,是英语学习者接触最早的用法,而且其用法也很多。其基本含义为“是”,基本用法结构为“主语+be+表语”,也就是常说的主系表结构,其中的表语一般都由名词、形容词、数词或表地点、时间等的短语来充当。
要看语句的时态:
如果是一般过去时,就用was/were
如果是一般现在时,就用am/is/are
如果是一般将来时,就用will be
如果是现在完成时,就用have/has been
如果是过去完成时,就用had been
