1. what - Which
2. cats 和 climbs不单配， 可以改为： cats - cat
3. dresses - dresses up
4. write - writing
5. boys - boy
1、what→which【“哪一个”都用which】
2、cats→cat或者climbs→climb【第三人称单数考察，cat单数搭配climbs，cats搭配climb】
3、dresses→dressed up【小孩的妈妈已经给小孩穿好衣服了，所以小孩才能开起来很酷。所以这里是过去式，不能用一般现在时。】
4、write→writing【finish doing sth固定搭配】
5、boys→boy，在comes前面加个who【1、第三人称单数考察。因为后面的系动词为is，说明前面的boy是一个人。2、come和is在这一句话中，共用主语是不行哒~必须要改成从句的形式~who comes for shanghai就成为了定语从句，表示“从上海来的那个”】
希望对您有所帮助~
