主语是物时,且动词作不及物动词时,用主动代替被动,这句话的主语是book,且return后有to,所以它在此处作不及物动词,那么不是应该填return吗,为什么是be returned 希望得到解答,

具体的情况有这么一些,楼主可以择而观之:
(1) 某些连系动词
(1) (如look,sound,smell,feel,taste,prove等)要用主动表被动,因为连系动词为不及物动词,它们没有被动语态形式：That dog looks dangerous.那只狗看起来很危险.Your idea sounds a good one.你的想法听起来很好.My advice proved to be wrong.我的意见证实是错的.
(2) 当open,shut,lock,move等用作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：The door won’t shut.这门关不上.The supermarket doors shut automatically.超级市场的门是自动关的.注：该用法的不及物动词通常与can’t,won’t 等连用,注意它与用被动语态含义不同：The window won’t shut.这窗户关不上.(说明主语的属性(——窗户有问题了)The window won’t be shut.这窗户将不用关上.(窗户本身没问题,只是不用关)有时可能用主动和被动形式均可,只是强调重点稍有不同：Suddenly the door opened.突然门开了.(不强调动作执行者)The door was suddenly opened.门突然被打开了.(强调动作执行者)
(3) 当read,wash,clean,cook,cut,wear,carry等用作不及物动词且表示主语的某种属性时,通常要用主动形式表示被动意义：The cloth washes well.这种布料好洗.The book sells quickly.这书销售得快.This cheese doesn’t cut easily.It’s too soft.这乳酪不容易切,太软了.This shirt will wear very long.这衬衫可以穿很久.注：该用法通常与well,easily,slowly,quickly等副词连用,并且在用于以上意思时通常不宜直接使用被动语态形式.不过在某些特殊情况下也可用被动语态,只是含义稍有不同(用主动形式表示主语的属性,用被动形式表示动作执行者所执行的动作)：The sentences read clearly.这些句子读起来很清楚.((即这句子没有歧义)The sentences are read clearly.这些句子被读得很清楚.(指读的人读得好)另外,以上用法有时也可能用于进行时态：The vegetables are cooking.蔬菜正在煮着.Is the book selling well?这书销售情况如何?
(4) 某些表示开始和结束的动词(begin,start,finish,end等),当主语为事物且不强调动作的执行者时,可用主动语态表示被动意义：When does the concert begin?音乐会什么时候开始?The play ended at ten o’clock.戏10点钟结束.
(5) 有的动词本身含有被动意味,通常用主动形式来表示被动含义：Where is the new film showing?这部电影在哪里放映?My skirt caught on a nail.我的裙子被钉子钩住了.Soon the house filled with people.很快房子就挤满了人.
