核心句型：
Such a plan could cut both ways.
這個方案有利有弊。
cut both ways 字面意思是：“兩面都砍”，這就如同在說事物既有好的一面，也有其壞的一面；有有利的一面，也有不利的一面。這個習(xí)語的正確意思是：“有利有弊”。因此，當美國人說"Such a plan could cut both ways."時，他/她要表達的意思就是:"This plan has its pros and cons."、"Such a plan has its advantages and disadvantages."、"The plan has two different effects at the same time."。
