题目

请高手来看看include,included,including的用法
看看第3句有没有错.
1.fifteen persons were killed in the traffic accident,including a boy and a woman.
2.fifteen persons were killed in the traffic accident,a boy and a woman included .这句的included是不是一个BE+过去分词表被动的用法?
3.fifteen persons were killed in the traffic accident,includs
a boy and a woman.
主要是看第3句有没错呀

答案

是的.
一个男孩和一个妇女“被包括”在里面...
被动.
