2017年高考英語(yǔ)備考：現(xiàn)在進(jìn)行時(shí)的被動(dòng)語(yǔ)態(tài)具體用法

　　現(xiàn)在進(jìn)行時(shí)的被動(dòng)語(yǔ)態(tài)

　　例如：

　　The sports meeting is being held in our school.

　　我校正在舉行運(yùn)動(dòng)會(huì).

　　Another bridge is being built over the Changjiang River.

　　長(zhǎng)江上正在修建另一座大橋.

　　構(gòu)成：be being 過(guò)去分詞

　　例如：

　　A number of Dongfeng trucks are being shipped abroad.

　　一批東風(fēng)卡車正被運(yùn)往國(guó)外.

　　用法：

　　1)“be being done” 中的動(dòng)詞be應(yīng)隨主語(yǔ)(sing./ pl.)作相應(yīng)的變化.

　　2)將現(xiàn)在進(jìn)行時(shí)的主動(dòng)語(yǔ)態(tài)變?yōu)楝F(xiàn)在進(jìn)行時(shí)的被動(dòng)語(yǔ)態(tài)的關(guān)鍵是：把be doing變?yōu)閎e being done.

　　例1.The students are cleaning the classroom now.

　　→The classroom is being cleaned now.

　　現(xiàn)在學(xué)生們正在打掃教室.(are cleaning變?yōu)閕s being cleaned)

　　例2.The boy is counting some eggs.

　　→Some eggs are being counted.

　　那男孩正在數(shù)蛋.(is counting 變?yōu)?are being counted)

　　你也可以給他們對(duì)比講一下：現(xiàn)在完成時(shí)
