____more than 3000languages in the world
A there are thought to be
B it is thought to be
为什么选B呢?
____more than 3000languages in the world
要用there be 结构 应该这么用:there are more than 3000languages in the world
用 is thought to be 主语应该用it ,指代后面more than 3000languages in the world 这个事实.这里是省略了一个that:完整的是it is thought to be that more than 3000languages in the world
