【选择】much
 
【解析】
 
    在 than 比较结构中不能用双重比较级.more 是 much 的比较级,safer 是 safe 的比较级,两个不同词汇的比较级用在一起如同一山出现了二虎.
 
    比较级可以用副词修饰,强调比较程度的大小.用在比较级前常用的副词有 much,even,still,far,slightly,a little,a bit,如:
much safer 安全得多 // much more 多得多
even safer 甚至更安全 // even more 甚至更多
still safer 还要安全 // still more 还要多
far safer 远远得安全 // far more 远远地得多
slightly safer有点安全// slightly more 有点多,多那么一点儿,略微多一些
a little/bit safer稍微安全一些,// a little/bit more (同slightly more)

答Much,因为后面Safer已经是比较级了。不能再用More了

用much,已经有safer比较级了,不需要加more

这里应该用much
解析:much修饰比较级,而more本身就是比较级了,much more中much就是修饰more。
题中safer是比较级,所以只能用much来修饰。
