不是的。
句子出现
be动词,通常有下了几种情况:
1,
主系表结构,这时,表语是名词,代词,
动名词或形容词或
表语从句,如;I am a student。You are not the one..My job is teaching you English.He is tall.My question is how we will get there.
2,进行时态。这是,行为动词用ing形式。如:He is working very hard.I am playing tennis.
3,
被动语态。这时,be 后面是
过去分词。如:The tent was set up just now.The book was written by him.
4,固定短语be going to 这时,这个短语与后面的动词一起组成复合谓语
5, 固定短语be able to,这个短语与后面的动词一起组成复合谓语
6,固定短语 be used to /be accustomed to“习惯于。。。”
7,其它be +adj+介词结构,如,be interested in,be good at 数不胜数。这时,整个短语做复合谓语。
