求详解~~
答：本题考查make作复宾动词的用法.
make sth. +adj. 意为使.变得.,其中的adj.为宾语的补足语.
当sth. 为不定式（包括其复合结构for sb. to do sth.) 及 名词性从句（如that-从句）时,必须将其后置,并用形式宾语it来代替它.这个大家比较熟悉,如：make it possible (for sb.) to do sth.
一般情况下,作宾语的名词不后置,如：We plant trees to make our campus beautiful.
但是如果这个作宾语的名词较长（通常带有自己的定语）时,为避免头重脚轻,可将其后置.
本题即属于这种情况,make的宾语为一名词性短语,其中心词为public transportation,如果没有后面的这个定语（介词短语between the urban area and the rural area）,则说：make public transportation convenient. "使公共交通变得便利” 就可以了.但是它后面再加上一个between短语,如说：make public transportation between the urban area and the rural area convenient. 就不仅宾长补短语不平衡（作补语的形容词convenient相对较短, 离宾语中心词太远）,且及容易产生误解（有make sth. +介词短语作宾补的情况）.
但同时,却没有用形式宾语it来代替名词短语,而将真正的作宾语的名词短语后置的情况.
所以这一题选A不选B.
我们汉语可以这样也必须这按排语序：
磁悬浮列车已使得城乡之间的公共交通变得便利.
另外,如果这一题选B可以,那C也行.一题不能有两个答案.所以也可以判断B不是正确答案.
PS：这个句型由形式主语it,真主（不定式、名词性从句）后置演变而来.思维方式相同.
提醒一下,不是所有的名词性从句都可以用形式主语it来代替而“幕后指挥”的.
如：What we should do next is still a problem. 我们一下步该怎么办仍是一个问题.
-->It is still a problem what we should do next.
What he said is right. 他说的是对的.
却不可以说成：It is right what he said.
因为这个what从句,是相当于一个名词+定语.没有疑问的意味.不象前者,那个what是由疑问代词变来的.
举一个类似的例子,你就明白了.如:
The book is interesting.
The book that you lent me the day before yesterday is interesting. 你前天借给我的那本书很有趣.
想一想,可以说成：It is interesting the book that you lent me the day before yesterday. 吗?
不行的吧?
同理,我们可以说：I find the book interesting.
可以说：I find the book that you lent me the day before yesterday interesting.
但不说：I find it interesting the book that you lent me the day before yesterday interesting.
是同一个道理.
