My brother fell while he was riding his bicycle and hurt himself.这句话里面 hurt He hurt himself.这句话对吗 hurt是不是要加s he hurt himself by bike. 应该是he hurt himself 还是he hurts himself （luck）,he（ hurt） himself badly. 连词造句 himself,has hurt,he as a result of 和 because of 的用法区别是什么?he hurt himself as a result of his careless.==he hurt himself because of his careless.这两句话语法上应该都没有错误吧?但是如果选择题有as a result of 和because of两个选 he himself buit a science lab和he built a science lab himself这句话对吗 When he was playing football,he hurt himself 句型转换转成：He hurt himself_________ __________ ____________. -----(luck),he hurt himself sadly横线上填什么 he hurt himself yesterday 改为否定句和疑问句 he (hurt himself ) in the long jump提问 he hurts himself改一般疑问句和否定句和he hurt himself有区别吗? he himself saw the accident这句话的解释 如何理解这句话：he cut himself badly 怎么理解这句话He tried to calm himself,forcing.
