3 Don't forget to respond verbally too. Show an interest in what the other person is saying. If your new friend is interested in something you know nothing about, Shakespeare, for example, ask about it. Why was Shakespeare so famous? What plays did that guy write, again? What century did he live in? Convince yourself that you want to know, and soon you will be having a very engaging conversation.
积极回应对方的话题,如果确实不知道,可以请教对方,例如,如果对方说道莎士比亚,你可以问为什么他这么出名,他写过什么著作等等。
