Are you free on Sunday?

想要约会别人，首先要问别人有没有空?你可说：Are you available? / Are you free? / Are you busy? 都是‘你有空吗?’的意思，如果要问星期天有没有空，就是：Are you free on Sunday? 如果你有空，可以回答：I have no plans. (我没有任何计划)、I'm free. / I'm available.(我有空)、 I'm not busy.(我不忙)，如果不太肯定，可说：Let me check. (让我查查看) 或 I'll check my schedule. (让我查查看我的时间表)。

对话

A：(on the phone) Ok, see you on Sunday. Bye. Ricci, are you free on Sunday?

B：Yes, I don't have any plans yet. What do you have in mind?

A：Aunt Amy has invited us to her house for a weekend party.

B：Sounds great. I'd love to meet your family.

甲：(电话中)好的，星期天见，再见。丽琪，你星期天有空吗?

乙：有啊，我没有任何计划，你有何建议?

甲：艾美阿姨邀请我们这个周末到她家开派对。

乙：听起来不错，我也想认识一下你的家人。

约会的用语，前面我们有简单谈过了，现在不妨详细一点介绍应邀或婉拒的用语。 接纳人家的邀请，说话一定要显得雀跃，例如：I'd like nothing better.(再好没有了)、I'd like to very much. / I'd love to very much / With pleasure / Why yes, that would give me the greatest of pleasure.(我高兴之至)、That would be great fun.(那将是一大乐事)。Nothing better、the greatest of pleasure、great fun等说法颇为夸张，正是客气的表现。

假如答应赴约，但须迟一点到达或早一点离去，则可在上述说法之后补上一句：....but I may be a bit late.(但我可能会迟一点)、....but I have to go by X o'clock.(但我X点之前就得离去)。

又假如不能肯定能不能赴约，那么可用以下说法：I'll try my best to come. / I'll try to make it. / I'll come if possible.(我会尽量抽身前来)。

婉拒人家的邀请最是困难，但一般可用以下理由：What a pity! I have another engagement/appointment.(真可惜，我已约了别人)、Oh, shame! I have something else to do./ I'm otherwise engaged.(啊，真可惜，我有其它事情要办)、I'm afraid I can't. There's lots of work to do.(我恐怕不能来了，有很多工作要做)。What a pity、shame、I'm afraid. 等，当然也都是客气说法，表示不是不想而是不能赴约。
