[求助]自己觉得比较重要的关于比较的问题~请帮助下,共同进步!

我在看整理的语法ＮＯＴＥＳ的时候，关于比较方面，发现了一点不懂的地方，大家可以一起讨论一下，都是ＧＷＤ的，相对来说还是比较重要的．

1.Traffic safety officials predict that drivers will be as likely to exceed the proposed speed limit as they are the current one.划线句是将什么和什么比呢？

as likely to exceed the proposed speed limit as they are likely to exceed the current speed limit

2.The fitness program would serve more employees who are out of shape than it would employees who are fit.这个到底是省了哪个部分呢？感觉怪怪的．．

than it would serve employees

3.as little risk as one chance in a million of causing cancer....这个到底是把什么和什么相比呢？

把little risk和one chance in a million比。risk很小，小到只有百万分之一
