Good morning, everyone. Hard things with you. I hope you're all feeling well. I'll show you some special pictures at the beginning of this lesson. Do you know what their names are? Let's read 1A and choose a right picture for paragraph.

我们在进行图文配对的时候，可用排除法来解决问题。如我们可以看出图 a 中的是一种交通工具，图 b 中的是某种火车，而图 c 并不能确定它的名字。通过刚才的阅读，我们可以先从最后一段的 train 一词为切入点，确定最后一段描述的是ToB，然后根据第三段的名词 vehicle 确定它的描述是图a，那么最后就可判断出第二段描述的是图c，问题就迎刃而解了。

除了借助词汇进行判断，我们还可以借助语言环境来进行判断。请同学们看下面一组词汇和图片，我们可以根据 a 中的 rain 确定它与第三幅图片相匹配， as is the rain 酸雨。至于 b 和 c 两个名词，短语和名词，我们要根据语言环境来进行选择了。
