As is known to all, China is a developing country( )( )(属于)the Third World.

问题描述:

As is known to all, China is a developing country( )( )(属于)the Third World.

填现在分词belonging to,修饰country,做后置定语.
关于belong还有另外考点值得注意:
belong to作谓语时,不可以用于被动语态,也不能用于进行时.那这题可以写belongs to绝对不可以。如果用定语从句,可以说which belongs to但不直接填belongs to
