be和do怎么区分用法?
什么时候该用be,什么时候该用do我就没闹明白过,请高手给予直接明了的辨析和使用办法.
例句:1.Theories centering on the individual suggest that children engaged in criminal behavior because they (were not)sufficiently penalized for previous misdeeds.
2.Since you (are not)interested,I won't tell you about it.为什么用are,不用don't啊?
这俩词都各自在什么时候用啊.
答
1.be
1）be + adj./ n.adj./ n.做表语
2）be + V.PP(动词过去分词）一般现在时的被动语态
2.do
1）在一般现在时的否定句、一般疑问句里用作助词.否定句里do后面直接加动词原型.
其他的建议你多背背词组,比如be interested in ...
