A.divides B.will divide C.is dividing D.will be divided 【讲透例题】 1. 句意:他被要求五点前回电话,可是他忘了。本题考查动词的被动语态。分析句子结构可知,主语“He”与ask之间存在被动关系,应用被动语态;由“he forgot"可知,此处陈述的是过去发生的动作,应用一般过去时。因此空格处应用一.般过去时的被动语态。故选D。 2. 句意:这个蛋糕将被分成十块,这样每个人都可以尝一下。本题考查动词的被动语态。主语“cake"和“divide"之间存在被动关系,要使用被动语态。根据句意及“can taste"可知此处需用将来时,故选D。 【讲透考点】 (1) 解题技巧 ①找到主语 ②确定主语与谓语动词的关系(主动或被动) ③确定时态,选出正确答案 (2) 考点总结 ①Sb be asked to do sth 某人被要求做某事,be跟随时态变化而变化 ②Sth will be done 某事将要被做 【相似题练习】 1.- All food to students for free in our dining hall on the School Celebration Day. -Great!
