答案详解

1.[A]【解析】only if...意为“只有……才”，放在句首，主句需倒装；if only意为“只要，要是……多好”。

2.[D]【解析】这是虚拟语气中的混合条件句。从句与过去事实相反，且将and提前，采用倒装形式，而主句与现在事实相反，所以用would be。

3.[C]【解析】listened和read为一般过去式，demonstrate所表示的动作发生在listen和read之前，且是一个持续动作，因此用过去完成进行时。

4.[C]【解析】than前后所比较的对象应该保持一致，anyone else意为“任何别的人”，为一个整体，在else后加's的所有格形式。

5.[C]【解析】固定搭配cannot/can't（help）but表示“不能不，只能”，but后接不带to的不定式。
