A.fill B.filled C.are filled D.were filled
答案 C 句意:这些蛋糕里面装满了巧克力,请尝一块。本题考查时态和语态。主语These cakes与动词
fill之间为被动关系,由此可知本空用被动语态。又因为本句陈述的是客观事实,故本空应用一般现在时态,
故本题选择C。
2
一般过去时的被动语态
一般过去时的被动语态(主语 + was / were + done)
The building was built ten years ago. (肯定句)
→The building wasn’t built ten years ago. (否定句,在was, were 后加not)

A.buys B.bought C.is bought D.was bought
答案 D 句意:他五年前买了这辆车,但是它看起来相当新。本题考查时态和语态。根据时间状语five
years ago可知应用一般过去时;主语His car和动词buy之间为被动关系,应用被动语态,故选D。

一般将来时的被动语态 (will/shall/would + be + done)
(1)A new school library will be built next year. (肯定句)

A.replace B.replaced C.will be replaced D.were replaced
答案 C 句意:咱们等着看未来书是否会被网络代替。本题考查动词时态和语态。主语books与replace之间为被动关系,又因为指的是将来,所以用一般将来时的被动语态“will+be+动词的过去分词”。故选C项。
