你的句子不宜添加 how。句意：As time passed, people learned to accept the changes. 随着时间的推移，人们学会了接受这些改变。一般说来，当表示有意识地学习做某事时，后面的不定式有没有how都可以。如：She learned (how) to weld. 她学会了焊接。Later on I learned (how) to read music. 后来我学会了识谱。She learned (how) to turn a cartwheel. 她学会了如何做侧手翻。he finally learned (how) to drive at the grand old age of 70. 她最终在70岁高龄学会了开车。但当表示无意识地学习做某事时，后面的不定式通常不用how。如：I must learn to bite my lip. 我必须学会不乱说话。Very early in life when the baby feels the pangs of hunger, she learns to scream. 当新生儿感到饥饿时，就学会了喊叫。Since I had the accident, I’ve learned to take each day as it comes. 自从出了那次事故后，我就学会了一切顺其自然。

dollar 应改用复数，因为这样用的 dollar 是可数名词：Can I pay in US dollars? 我可以用美元支付吗？又如：The price of oil is given in US dollars. 石油的价格是以美元标价的。The borrowings were denominated in US dollars. 借款以美元结算。
