1.No permission has __for anybody to take photos here. A.given B.been giving C.be giving D.been given 2.I shall go to Las Vegas before you__back next week. A.will come B.came C.would come D.come 能帮忙解决下吗？谢谢。

第一题：No permission has __ for anybody to take photos here.考察你的被动语态和现在完成时的用法。permission和give是动宾结构，所有用given。本句译为“到目前，没有人被允许在这里拍照。”用现在完成时。所以选D 第二题：I shall go to Las Vegas before you__back next week.考察一般将来时的用法，before在一般将来时中遵循“主将从现”的规则。
