it is reported that a new house _ _ ( build )at present in the disaster area为什么答案是 is been built?而不是 is being built

问题描述:

it is reported that a new house _ _ ( build )at present in the disaster area
为什么答案是 is been built?
而不是 is being built

be doing 是现在进行时;be done 才是表被动态的,此处用后者,表房子被建

不会吧亲
答案一定是错了
就应该是is being built

答案错了,正确答案应该是is being built,is been built有明显语法错误,应该是has been built.
