Wow!There are so many cars in the street.We will be late unless the bus ____fly.
A.is able B.will be able C.is able to D.will be able to
这个又选啥?是什么语法!谁教教我!

so 表示的意思是如此,非常的意思,它是一个副词,用来修饰形容词；such是一个形容词,用来修饰名词,题目中的 hard time 是一个名词词组,所以首先选用such,而不是so.time 是一个不可数的名词,但是之间加了一个冠词a,这是一个习惯性的用法,可能很多英语爱好者在这个语法上不理解,有许多这样用的情况,例如：have a good time,a heavy rain,a strong wind,a big smile,etc.
Wow!There are so many cars in the street.We will be late unless the bus ____fly.
A.is able B.will be able C.is able to D.will be able to
这个题的答案应该是D.首先是考察 be able to 这个结构.然后就是虚拟语气了.
