1.oranges are sold in the shop.2.oil is not produced in America.3.How many TV sets are sold by you last week?4.Helen was sent by her parents to school when she was nine.5.the same mistake cannot be made by us twice.第12题因为是泛指 所以by them 和by people 可以省略哈.======以下答案可供参考======供参考答案1:1.Oragnes have been sold in the shop.2.Oil is not produced in America.3.How many TV sets were sold by you last week?4.Helen was sent to school when she was nine.5.The same mistake can't be made by us twice.供参考答案2:Oranges are sold in the shop.Oil isn't produced in America.How many TV sets were sold last week?Helen were sent to school by her parents when she was nine.The same nistake can't be made twice.供参考答案3:the oranges in the shop are sold oil is not produced in Ameticahow many tv sets were sold last week?Helen was sent to school by her parents when she was nine.the same mistake can't be made twice. 1.2的确是泛指，第三句不要by you因为1.很少有这种说法，2.这句是疑问句，直接问当事人，不会有歧义的。关键被动语态也不强调人的能动性啊。。。。还有第四句的by的位置，我觉得我这种说法最舒服。最后一句可以说是一句名言，坚决不要by us。而且即使不是名言。by us的用法也很怪异供参考答案4:1.Oranges are sold in the shop by them.2.Oil aren't produced by people in America.3.How many TV sets were sold by you last week?4.Helen was sent to shool by her parents when she was nine.5.The same mistakes can't be maken twice.供参考答案5:1. Oranges are sold (by them) in the shop.2. Oil is not produced(by people) in America.3. How many TV sets were sold by you last week?4. Helen was sent to school by her parents when she was nine.5. The same mistake can't be made (by us) twice.括号里面是动作发出的对象，语法上正确，但加上会读起来很怪。
