问题描述：
he described it as a very agreeable situation located within two small hills in the midst of which flowed a great river.
这句话里面的 in the midst of which中这个which是指hills吗?如果是的话是指其中一起hill还是2个hill,which可以指复数形式吗?
还有 in the midst of这里的mindst和middle有什么区别,如果写成in the middle of which可以吗?这2个词区别在哪呢?
答
which指代的是two smal hills, 假如是其中一个,会表述称in the midst of one of which
which 可以指代复数；
几乎没有区别,midst 更强调正中间within是表示在hills之内对吗？ 那可以用in吗宽泛来看是可以的，细细品味略有不同。in 表示在。。里面，而within 含有夹在。。里面的意思
