I'd like to tell you about the table manners __ you should know when you visit Korea.

问题描述:

I'd like to tell you about the table manners __ you should know when you visit Korea.
A.which B,who C.what D,how
选哪个关系词,为什么

A 【you should know 】是一个定语从句,mannners在定语从句中作宾语,原选项中,只有which可以在定语从句中做宾语.
欢迎追问.但是答案是what,你的不对啊(⊙v⊙)嗯我确定选A答案错了
