这篇文章的原文是：Last week I went to the theatre. I had a very good seat. The play was very interesting.I did not enjoy it. A young man and a young woman were sitting behind me. They were talking loudly. I got very angry. I could not hear the actors. I turned round. I looked at the man and the woman angrily. They did not pay any attention. In the end, I could not bear it. I turned round again. ‘I can't hear a word!’I said angrily. ‘It's none of your business,’the young man said rudely. ‘This is a private conversation!’[hjmAdHolder]

         图标释义：一个椭圆加上下面的两只腿表示人。人头中的字母I表示“我”，M和W上下相对表示课文中的那对男女，时钟图符表示与时间有关的单词，叉表示“否定”，耳朵表示“听”，嘴巴表示“说、吵”，两口相对表示“谈话”。

       首先从图中左上角的实心圆点开始念。曲线从实心圆点出发后，遇到了时钟图符，表示这里有一个与时间有关的单词。对照图形下面的课文，得知这个单词是“last week”。然后，曲线又遇到人形图符，表示这里有一个与人有关的单词。对照课文，这个单词是“I”。继续沿曲线走，就会发现“go to”和“theatre”。于是，上述的这几个单词就组成了课文的第一个句子：Last week I went to the theatre。

        注意需要把图形中的go to变为正确的时态went to，而且theatre前的冠词“the”也被省略了。所以，在图中出现的单词，被称为课文的关键词。当熟悉这个图形后，即使不给出关键词，也能很快看图复述整篇课文。没有关键词的思维导图，称为“纯思维导图”。
