很简单，finished是非谓语动词中不定事作形容词，但由于finish后如果接动词的话应接动词的-ing形式，所以我们可以把be finished doing sth看做是一个固定词组，译为“结束做某事”

不正确。be finished表示被动。Xiaomin是finish这个动作的发出者，即Xiaomin还未读完这本书，所以因该用主动形式。因改为： He wants to borrow her book，but Xiaomin has not finished reading it.

is 改成has,一般完成时否定式(has/have not done sth.)表示动作尚未做完,finish + doing sth.表示完成某事.全句的意思由but这一个转折可知,xiaoming书还没看完.

不正确。后一句应改为:but she has not finished reading it.

have/has+动词的过去分词.系动词不能直接跟行为动词!

我英语不好，不过好象不太顺口
热心网友
好
热心网友
but xiaomin has not finished reading it
热心网友
不正确，后句应改成But Xiaomin has not finished reading it.因为xiaomin是read这个动作的执行者，不能用原句所使用的被动语态，且finish加了ed,所以“还没读完”只能用完成时
热心网友
but xiaomin has still not finished reading it.

不正确。后一句应改为but xiaomin has not finished reading it.
