That dog looks dangerous. My advice proved to be wrong.(2) 当open, close, shut, lock, move等用做不及物动词且表示主语的某种属性时,通常用主动形式表示被动意义。他们通常与can’t, won’t等连用。The door won’t shut.Suddenly the door opened. (不强调谁开了门)(3)当read, write, wash, sell, clean, cook, burn, draw, cut, wear等词与well, easily, quickly 等副词连用时,常用主动表被动。The cloth washes well. The poem reads smoothly. The book sells well. This cheese doesn’t cut easily. It’s too soft. This shirt will wear very long. The floor doesn’t clean easily. This kind of rice cooks more quickly than that kind.但是别的时候要看具体情况而定:This book sells well. So far, 200 books have been sold out.The sentence was read clearly by her.(4) 某些表示开始和结束的动作(begin, start, finish, end, etc.),当主语是事物且不强调动作的执行者时,可用主动表被动。When does the concert begin? The play ended at ten o’clock.2.非谓语动词主动表被动的情况:(1)不定式to blame, to let用做表语时,通常用主动表被动。Who is to blame?(该怪谁呢?) The house is to let. (此屋出租。)(2)在“be +形容词+to do”结构中的不定式通常……The question is difficult to answer. Do you think the water is safe to drink? (3) 不定式用于某些动词的(have, have got, get, want, need)宾语后做定语时:I have some letters to write. I want something to drink.但是注意:I have something to type.(我自己打) I have something to be typed. (请别人打)所以:当不定式的逻辑主语和句子的主语一致时就用主动表被动,若不一致,则需用被动表被动。I have a letter to post. (自己寄) I have a letter to be posted. (请别人寄)(4)be worth doing; need / want / require doing (to be done)结构中In all, the book is worth reading. This might be worth thinking about. The plants want watering / to be watered every day. The wall wants repairing / to be repaired.但是:be worthy to be done / of being doneThis book is worthy to be read / of being read.(2004高考 江苏卷) More patients _________in hospital this year than last year.
