把賓語(yǔ)用作被動(dòng)語(yǔ)態(tài)中的主語(yǔ);
注意人稱、時(shí)態(tài)和數(shù)的變化。
例：1. Bruce writes a letter every week. →A letter is written by Bruce every week. 2. Li Lei mended the broken bike this morning.→The broken bike was mended by Li Lei this morning.
He has written two novels so far.→Two novels have been written by him so far. 4. They will plant ten trees tomorrow.→Ten trees will be planted by them tomorrow. 5. Lucy is writing a letter now.→A letter is being written by Lucy now.
