stand up to是什么意思？
例句：
I am very disappointed in the quality of the product; it doesn't stand up to your advertisement.
stand up to sb/sth
经得起；抵抗；勇敢地面对
英文解释：
to defend yourself against a powerful person or organization when they treat you unfairly当一个有权势的人或组织不公平地对待你时，要保护自己to not allow yourself to be treated badly, especially by someone in authority不允许自己被不公平地对待，尤其是那些有权有势的人to refuse to accept unfair treatment from a person or organization拒绝接受个人或组织的不公平待遇。
例句：
Milly alone was brave enough to stand up to her.只有米莉有足够的勇气反抗她。He’ll respect you more if you stand up to him.如果你勇敢地面对他，他会更尊重你。He hit me, so I hit him back–the first time in my life I'd stood up to him.他打了我，所以我也打了他——这是我平生第一次反抗他。
这几个主流词典中的英文解释，主要偏向了“反抗，抵抗”的意思，即：
If you stand up to someone, especially someone more powerful than you are, you defend yourself against their attacks or demands.
如果你stand up to某人，尤其是比你更强大的人，你是为了保护自己免受他们的攻击或要求。
最后在柯林斯词典中找到了比较符合篇首例句中stand up to的解释：
If something stands up to bad conditions, it is not damaged or harmed by them.
如果某样东西经得起恶劣条件的考验，它就不会被这些条件破坏或伤害。
现在重新来看这句话：
I am very disappointed in the quality of the product; it doesn't stand up to your advertisement.
大概意思是：我对产品的质量非常失望，它与你的广告不符，你的广告经不起考验。
拓展：
stand up to和stand up for相差一个单词，意思却完全不同！
stand up for sth/sb：支持，坚持；拥护
英文解释：
to defend or support a particular idea or a person who is being criticized or attacked捍卫或支持某一观点或某一被批评或攻击的人
例句：
You have to learn to stand up for yourself.你必须学会维护自己。/你要学会自立。You have to stand up for your rights - you can't let them walk all over you.你必须捍卫自己的权利——你不能让他们践踏你。
