【3】Some flowers were bought for him by Mary.

【4】That set of keys was looked for by them just now.

【解析】

【1】賓語(yǔ)two books是復(fù)數(shù)，變?yōu)橹髡Z(yǔ)，謂語(yǔ)wrote是一般過(guò)去時(shí)，故改為被動(dòng)形式的謂語(yǔ)用復(fù)數(shù)形式were written。故為Two books were written by Mr. Green last year.

【2】賓語(yǔ)them變?yōu)橹髡Z(yǔ)they，謂語(yǔ)用復(fù)數(shù)形式，根據(jù)saw可知此處用一般過(guò)去時(shí)，故為were seen。故為They were seen to come into the room by her.

【3】賓語(yǔ)some flowers變?yōu)橹髡Z(yǔ)，是復(fù)數(shù)形式，謂語(yǔ)bought是一般過(guò)去時(shí)，故變?yōu)楸粍?dòng)形式為were bought。故為Some flowers were bought for him by Mary.

【4】賓語(yǔ)that set of keys是單數(shù)，變?yōu)楸粍?dòng)形式，作主語(yǔ)，謂語(yǔ)looked for是一般過(guò)去時(shí)，變?yōu)楸粍?dòng)形式為was looked for。故此處為That set of keys was looked for by them just now.

【5】賓語(yǔ)a radio變?yōu)楸粍?dòng)形式，作主語(yǔ)，謂語(yǔ)用單數(shù)。謂語(yǔ)動(dòng)詞brought是一般過(guò)去時(shí)，故此處的被動(dòng)形式為was brought。故為A radio was brought to school by him today.
