1.There was a place it's called "pollybee".

1.There was a place called "pollybee".there was a place 和it's called pollybee 分别是两句完整的句子不能没有连词连接,要么当中加逗号and ,要么就改成主从复合句2.Beijing is the city that I most want to go to. go 是不即物动词,要在后面加to 才能接宾语,因此这里漏了to ,或者改成…the city where I most want to go .因为where 可以替代to which 这个介词宾语结构

删除 it's
后置定语，也就是修饰语 called "pollybee".
用来修饰place的
go.后面加to
把句意理我最想去的城市是北京，再吧句子倒过来翻
I most want to go to the place is beijing.
that I most want to go to也是后置定于，（修饰语）用来修饰the city

1.There is a place called "pollybee"
2.Beijing is the most city that I want to go to.

1 it's去掉
直接called 。。。就行了
2that去掉
还有，那个is你打反了
