51. The two thieves have been disappeared. disappear 为不及物动词,因此不能用于被动语态。所以把 been去掉。
52. The building built now will be our teaching building. 表“现在正在建的”应用被动语态的正在进行时,因此在built 前加being。
53. He is being operated by the famous doctor. 主动语态变为被动语态时,应注意短语动词的完整性,别忘了介词或副词。“给…做手术”应为operate on sb,所以在operated 后加上on。
54. I wonder if the doctor has been sent. 原因同上,应在sent 后加上for。
55. The book written by him is sold well. 说一本书畅销是指书本身的属性,因此不用被动语态。本句应改为:The book written by him sells well.
56. This history book is worthy reading. “值得被做”可以有如下几种说法:be worth doing; be worthy of being done; be worthy to be done. 因此本句应该为:This history book is worthy to be read. |
