I have two brothers 我有两个兄弟
学习 11 到 100 的数字(eleven~hundred)和复数 -s。许多语言不强制标记复数,学习者常漏掉 -s。英语在数字后的名词必须用复数:不是 two brother,而是 two brothers。还有一个不规则:child → children。
Dialogue
Two Brothers — 两个兄弟
- Emma Minsu, do you have brothers? 民秀,你有兄弟吗?
- Minsu Yes! I have two brother. 是的!我有两个兄弟。(错误:数字后要用复数——brothers)

- Minsu My brothers are twelve and fifteen. 我的兄弟一个十二岁,一个十五岁。
Dialogue
One Hundred Students — 一百个学生
- Jack Minsu, are these your friends? 民秀,这些是你的朋友吗?

Grammar
复数名词:-s
Explanation
英语用名词加 -s 来表示"不止一个":one brother → two brothers,one book → three books。大于 1 的数字后面,名词总是复数——不能说 "two brother"。大多数只加 -s,常见的不规则只有一个:child → children。很多语言不标记复数,所以容易漏掉 -s,但在英语里,数字后面的 -s 不是可有可无的。
Examples
- I have two brothers. 我有两个兄弟。
- She has three friends. 她有三个朋友。
- They have five books. 他们有五本书。
- I have one child. They have two children. (irregular) 我有一个孩子。他们有两个孩子。(不规则)
