there are two zooes in my city.这个句子对吗?

1.there are two zooes in my city.这个句子对吗?
解析 zooes-----zoos
2.I have been to three three times.( )
解析 to 后面要加一个地点
3.sydney is famous for CN tower.( 对 )
4.My cousin comes from the USA.( 对 )
5.some childrens are playing in the park.( )
解析 childrens ---- children

zoo的复数直接加s就可以了吧

zoo的复数 是 zoos 而不是zooes

第一个three 改为 there

CN tower 是加拿大的，改为 sydney opera house 悉尼歌剧院

the USA 改为 USA

children 本来就是child的复数形式，所以，childrens 改为 children
