A.being built B.to be built C.built D.building

优质解答

The bridge ___ next year will be very long. A. being built B. to be built C. built D. building
选B
因为有next year
所以应该表示将来
所以用不定式
另外桥是被造的,所以用不定式的被动语态
有不会的可以再问我

追问：

为什么表将来用不定式？是不是也可以这么说The bridge which will be built next year...

追答：

那是定语从句啊 这边用的是非谓语 这边没有定语从句的选项 因为后面有了谓语动词【will be】所以只能用非谓语
