有关被动语态的几个重要考点
、■将语态与主谓一致结合起来命题
1. All the employees except the manager ______to work online at home.
A. encourages B. encourage C. is encouraged D. are encouraged
解析：主语是all the employees(复数) ，而不是the manager，排除答案A和C；又因all the employees与encourage是被动关系，要用被动语态，排除B，故选D。
2. A library with five thousand books _______to the nation as a gift.
A. is offered B. has offered C. are offered D. have offered
