Essentially, there were reports that Trump felt that McMaster would be lecturing to him and maybe talking down to him.

基本上来说，有报道称特朗普认为麦克马斯特会给他上课，可能会用居高临下的语气对他说话。

When someone is talking down to someone else, the person talking is treating the other person as if they were lower than them, less important than them, or, again, not quite as smart as them.

当某人对别人说话时，说话的人对待对方的态度就好像他们比他们低， 不如他们重要， 或者再说一遍， 不如他们聪明。
