if you come to visit our home i will offer you

问题补充：

if you come to visit our home,i will offer you

答案：

如果你写的没有错误,那么我只能说是你的老师有问题.A是口语里特别常见/常听到的说法.而B如果改成some Chinese food还好,something Chinese food 连逻辑都不对,谈何语法?

======以下答案可供参考======

供参考答案1:

I will offer you something to eat.

I will offer you some Chinese food to eat.

供参考答案2:

A:是一些中国的什么东西

B：是中国的食品，

依题意，应当选B
