指示代词This与That的前指与后指

　　关于指示代词this与that的前指与后指，请注意以下两点：

　　1. 如果是前指（即回指前文提到的事情），可用that或this。如：

　　She married Jim， and this [that] surprised me. 她嫁给了吉姆，这使我感到很吃惊。

　　John had a bad cold. That [This] was why he didn't turn up. 约翰患了重感冒，这(那)就是他没有来的原因。

　　It was always said of the Princess that she had the common touch and that [this] was why she was so well loved by the people. 人人都说王妃平易近人，也正是因为这一点她才会如此深受民众的爱戴。

　　注：回指上文的 that 在译成汉语时，通常也译为“这”。如：

　　That's where you are wrong. 这就是你不对的地方。

　　2. 如果是后指（即指后文叙述的事情），则通常只用 this。如：

　　I want to know this: is he healthy? 我想知道这一点：他是否很健康。

　　Answer me this: how did they know we were here? 回答我这个问题：他们怎么知道我们在这儿？
