帮我把下面句子改成被动语态,
He often helps Tom when he in trouble
We saw a small boy lying on the ground
We heard her sing at the party last Sundy
We should speak to old men politely
We will plant millions of trees this year

第一句我觉得句子本身应该是 when he is in trouble 吧 是漏打了还是怎么样?
第二句 The small boy was seen lying on the ground by us .
第三句 Her sing was heard by us at the party last Sunday.
第四句 Old men should be spoken politely.
第五句 Millons of trees will be planted by us this year.
