正确讲法应该是这样:
My English is a little weak.
更可以这样说:
Please forgive me if I make any errors; my English is a little weak.
(如果有任何错误,请多多包涵;我的英文不太好。)
如果要向别人解释自己英文不好,绝对不要使用“poor”这个字,因为这是错误用法,你可以有其他说法,例如:
1. My English isn't very good.(我的英文不太好。)
2. My English is pretty basic.(我只会简单的英文。)
3. My English is pretty limited.(我懂的英文非常有限。)
My English is poor.
I don't speak English well.
My English is not very good.
I can't speak English very well.
My English is bad.
My oral English is not well。
