those gril's are,those are office?

问题描述:

those gril's are,those are office?
those grils are very lazy.
those are office assistants.
从语法上讲哪句是错的?为什么?
其实2个句子都是对的。只是我不清楚those grils are very lazy和those are grils very lazy有什么原理区别,those are grils very lazy不是和those are office assistants一样吗?但是课本说我的those are grils very lazy是错的。

those grils are very lazy.
those are office assistants.
的确都是对的.
都是系表结构的句子.BE动词是常见的系动词.表语由形容词和名词词组担任.就像上面两句一样.
those are grils very lazy是错的.因为very lazy是形容词短语.只能作定语或表语.定语是修饰名词的.所以这句只能改成 those are very lazy.或.those are very lazy girls.
建议你看两个东西.一个是句子成分.一个是系表结构.
