英语句子用法错误分析

下面的三句话每一句都有错误，你能把错误找出来吗（答案写在文末）：
 

1. Did you know how to go to the restrooms?

2. He has been married since two years ago.

3. I don't have some.
    
   

   
    
   正确答案
    
   1.
    
   ❌Did you know how to go to the restrooms?

✔️Do you know how to go to the restrooms?
 
Did you know 和 Do you know 在中文里没有区别，但在英文中却可以表示不同的意思。

Do you know 是一个真正的提问。提问者一般不知道问题的答案。

而 Did you know 是用来作为一个新闻或段子的开场白，提问者本身已经知道问题的答案了。如：
 
Did you know a lobsters blood is colorless but when exposed to oxygen it turns blue。你知道龙虾的血液是无色的，但遇到氧气会变成蓝色吗?
 
本道题"Did you know how to go to the restrooms?"（ 你知道怎么去洗手间吗？）明显是一个真正的提问，所以应把 Did you know 改为 Do you know .
 
2.
 
❌He has been married since two years ago.

✔️He has been married for two years.

✔️He was married two years ago.
 
since 和 ago 一般不能同时使用。
 
ago+时间段，一般用于过去时。

Since + 时间点，通常用于完成时态。

For + 时间段。可以用于任何时态。
 
"结婚两年了"属于"一段时间"而不是某个具体的"时间点"。因此修改时可以保留ago去掉since，或者替换为 for 也是正确的。
 
3.
 
❌I don't have some.

✔️I don't have any.
 
Some 用在肯定句和疑问句中。表示不确定数量的人或物。如：

I have some money in my pocket.

或：

Would you like some ice cream?
 
但 some 不能用在否定句中做宾语。原句应替换为 any。
