“鱼和熊掌不可兼得”用英语怎么说

中国有句古话“鱼和熊掌不可兼得”，本意不是说二者必然不可兼得，而是强调当如果不能兼得的时候，我们应当如何取舍。

英文中也有相类似的表达，但是这个句子和鱼，还有熊掌都没有什么关系。英文的表达为：

You can"t have your cake and eat it, too.

例句：

You can"t have your cake and eat it - if you want more local services, you can"t expect to pay less tax.

你不能二者兼得——想获得更多的地方服务就不能指望少付税金。

You"re never going to save enough money to buy a house if you keep buying expensive appliances and cars. You can"t have your cake and eat it, too.

如果你继续买昂贵的家电和汽车，你永远攒不够买房子的钱。二者不能兼得。

Too many people want to have their cake and eat it, demanding all sorts of social benefits from the government but being unwilling to pay any taxes to fund them.

太多人想鱼和熊掌兼得，要求政府的各种社会福利，但是又不愿意交税。
