近来帮我看看一段英语对不对
In January,the White House will be welcoming its first black host:Barack Obama; it’s a milestone that proves the achievement of integrating diverse races together which has been done by the government of The United States.
这句话通吗?或者有什么更好的说法?
In January,the White House will be firstly hosted by an African American:Barack Obama; it’s a milestone that proves the achievement of integrating diverse races together which the government of The United States has reached.
我采用了3楼第一句 我做了下修改麻烦看下这样行不？
