然而，刺激经济的财政政策在亚洲比在美国或欧洲更有效，因为亚洲家庭不承担巨额债务。 所以税收减免或现金补助更可能用于支出而不是储蓄。

with huge debts, so tax cuts or cash handouts are more likely to be spent than saved.

我要给你写封感谢信，但是我还得给另外两个人写信，只需要写一封信，同时发给他们，这样更有效率，因为还没给他们写，所以也没给你写。

I have a thank you letter I need to write but there are two more people I need to send a letter to also and it would be efficient to send them at the same time.

她说：“女性可能在选择与之生育后代的伴侣时需要更有效地识别能力，所以她们在繁衍过程中具备了优于男性的某种能力。”

She said: "Women perhaps need to be more discriminating when they choose who to mate with to produce offspring, as they invest more than males in the reproductive process."

The z effective is lower, so we have to put less energy in to get an ion out.

它的有效核电量更低，所以我们只需要更少的能量就能打出一个离子。

The reason it's aluminum is because aluminum has a lower z effective, so it's not being pulled in as tightly by the nucleus, and if it's not being pulled in as tightly, you're going to have to put in less energy in order to ionize it, so that's why it's actually going to have the smaller ionization energy.

原因是,铝的有效核电量更少，所以没有被原子核束缚得更紧，而如果没有被束缚得更紧，你为了电离它所需要注入的能量也就更少，这就是,它的电离能会更低的原因。
