Thanks for ___ (ask) us to come to your brithday party.

问题描述:

Thanks for ___ (ask) us to come to your brithday party.

因为for是介词,介词for的后面可以用名词作宾语,也可以用动名词形式作宾语,所以答案应为:Thanks for asking (ask) us to come to your brithday party.

Thanks for asking (ask) us to come to your brithday party.

for 是介词,后面接名词或者动名词,所以是asking
