2...to give handshake to each other
第五题感觉怪怪的,但不知道哪里错了

句子要符合结构,主谓一般只有一个,除非具有从句.修改如下.
1.这应该时两个句子,不能仅用逗号隔开,应该改成Joe is polite,and he greets everybody politely.或者 Joe who is polite greets everybody politely.(从句)
2.同样道理,应该改成In fact,the children don't like to give a handshake to each other,and they usually hug each other when they meet.
或者In fact,the children don't like to give a handshake to each other.They usually hug each other when they meet.
