The World Expo_____in Shanghai now.A.being had B.is having C.is holding D.is being held 为什么选D

The World Expo_____in Shanghai now.A.being had B.is having C.is holding D.is being held 为什么选D
选D.
原因有两个
1,因为是被动语态,“世界博览会被召开”,所以需要用被动形式.
2,因为句尾有now,所以要用进行时,“世界博览会正在被召开”
所以结合起来要用“被动进行时”----is being held.
)

D 被动的进行时 D D.is being held 被动语态的现在进行时

首先这个世博会是被人们举办的，要用被动语态，其次这里的名词后要有谓语动词，应为是单数所以要有is，c是主动形式，a缺少谓语is，b也是主动形式。只有选D。
希望能帮到你

被动式加进行时。

d
现在进行时的被动语态
