situational discourse的用法和样例：
例句
- Each text contains a short essay and several situational dialogues, which are to be learned complementarily to achieve an accelerated result.
课文包括短文和情景会话两部分，交叉学习，事半功倍。 - If you read any situational English book and try to collect all the useful words and sentence patterns from it, you'll know what I am saying here is definitely correct!
这并非无废话哦，不妨找本情景会话英语书仔细看看，并把每个情景的常用的句型和词汇摘录就可知道我所说的是否属实了。
