That your friend didn’t offer you a gift on your birthday ________ that he will break away with you.

A.don’t mean

B.doesn’t mean

C.didn’t mean

D.hadn’t meant

答案及解析： B

解析：

本题考查主谓一致和时态。句意为：你朋友在你生日这天没有给你礼物并不意味着他和你断绝来往。从句作主语时谓语动词用单数，此句的主语是that your friend didn’t offer you a gift on your birthday；

根据后面的will break away可排除后两项。
