Of all the 40 students in this class,20 students are girls,20 students are boys and all have toys

问题描述:

Of all the 40 students in this class,20 students are girls,20 students are boys and all have toys
从语法角度讲这句话对吗?怎么改呢
重点是20 students are girls,20 students areboys 这两句话各是个完整的句子啊。能这样用吗?

首先,20 students are boys是多余的.前面部分已经暗含了这一句的意思在内了,一个人不是男的,就是女的,不可能有第3种情况存在.
去掉多余的部分后,剩下的两个分句用and连接,就更容易让人接受.后面分句最好加上they做主语.
