【问】 “Are you done with the book I gave you?”
 “Not quite. I’ve read all____the last chapter.”
 A. but B. until C. just D. yet(TOEFL，70.6)
 上面的are you done with是我无法理解的。句中的主语难道不是施动者，而是受动者吗?
 【答】 在一般的句子里，be done的主语是受动者，例如：
 1. She interrupted him before his speech was dome.(MD)
 他尚未结束发言，她就打断了他。
 2. He arrived after dinner was done. (MD)
 饭做好后他才到达。
 3. Work waiting for them back on the prairies when the fun was done. (ECWO)
 嘻笑之事一结束，大草原上还有工作等待他们回去做。
 4. The job is finally done. (ECD)
 那项工作终于完成了。
 英语里还有一个have done(with)结构，在这个结构里，主语是施动者：
 1. When you have done，come back!(LDCE)
 你干完了就回来。
 2. Tom keeps asking me for an opinion on his book so I’d better read it and have done withit. (LDPV)
 汤姆老是征求我对他写的那本书的意见，所以我最好还是读一遍，了却这件事。
 3. Let us have done with it.
 让我们把这件事干完吧。
 be done with是一个特殊结构，它的主语并不是受动者，而是施动者。这是跟其语法结构相矛盾的。这种情况并不仅仅限于be done with。be finished等也是如此(参见finish)。
 下面再列举一些be done with的例句：
 1. Are you done with the newspaper?
 你读完那份报纸了吗?
 2. I wish to be done with my task.
 我希望把我的工作干完。
 3. I am done with writing him letters asking him to pay his bill;now I am going to turnthe matter over to my attorney.
 我已经写过信向他讨帐;现在我要把这件事交给我的律师去办理。
