我认为您们应该给工程投永久性和临时性的保险。

I suppose you should have both the permanent and temporary works insured.

非永久性的收入增长（失业保险肯定就不是永久性收入来源）诱使人们相对增加了开销，从而导致了财政刺激的失败。

The stimulus failure is due to the relatively small increase in spending induced by non-permanent increases in income (as unemployment insurance is certainly not permanent source of income).

世上没有“保险单”保证你们的关系能够维持永久，但是跟随你大脑的理智而非心跳的冲动，你将会有更好的成功机会。

There are no guarantees that a relationship will last forever. But by following you head rather than your heart, you will have a better chance of success.
