The engineers had __ trying to solve the mechanical problems of the railway system
the engineers had____trying to solve the mechanical problems of the railway system
a such hard time
b such a hard time
c so hard time
d a so hard time
为什麼呢?
首先so 和such的区别:a/an+so+形容词+名词;such+a/an+形容词+名词.
例如a so beautiful girl= such a beautiful girl 如此漂亮的一个女孩
第二点:在这里hard time 相当于一件困难的事情,一段难捱的时间,是可以加冠词a的
相当于我们经常说的have a good time 玩得高兴
