在之前的节目中我们谈到过如何进行预约，那么今天来我们来看看如何取消或改变：

A:I'm calling about your appointment.Mr.Smith has to cancel all his appointments because he's got something urgent to attend to. (现在打电话是预约的事，史密斯因为有事处理不得不取消所有约会.)

B:When can I go to see him? (我什么时候可以去见他呢?)

A:Anytime except today.Please give him a call before you come. (除了今天什么时候都行,来都给他打个电话.)

B:OK. (可以.)

Notice：当你和别人约好做一件事情，但是后来又想取消，该怎么说呢？Scratch这个词可以帮你的忙。Scratch在词典里的解释是"用指甲或是爪子去刮；涂鸦、随手乱画"。在口语上，scratch something便衍生为"取消"或"删除"原来的计划。再说得简单一些，scratch这个用法跟我们常讲的forget这个词十分类似。例如本来约好明天要去看电影，但你临时想取消，这时你可以说，"Let's forget it."或是换句话说"Let's scratch the plan."

A:Will you be available on Saturday or Sunday?(你星期六或星期天有空吗？)

B:Scratch the Saturday thing. I'll be available only on Sunday evening. (星期六我不行，我只有星期天晚上可以)

这句话完全就等于"Forget about Saturday. I'll be available only on Sunday evening."

接下来提供大家一些改变约会的常用句型：
