【当做主动词时，“be”在性质上属于接系动词(The Linking Verb), 后面要有名词、形容词、地方副词或短语作补足语(The Complement)。】例如： The man is a science teacher. 这个男子是一位科学教师。 Mary's new dresses are colourful. 玛丽的新衣服色彩鲜艳。 I havebeen there before. 我以前去过那里。 My motheris in the kitchen now. 我妈妈现在在厨房里。
★这四个都是陈述句，可以变成疑问句，方法简单，把主语和“be”或助动词对换位置即可： Is the man a science teacher? Are Mary's new dresses colourful? Have I been there before? Is mother in the kitchen now? ★当“be”要在祈使句中出现时，陈述句可借助助动词“do”，否定句必须在前加上助动词“don't”，如： Don't be silly! Do be obedient! Be careful! Don'tbe a fool! ★“Be”有两种缩写法，如下： He's not...../He isn't.... You're not...../You aren't... ★但“am + not”的缩写法只有一个： I'm not. 有人用“ain't”, 但这并不是标准英语。
