It is interesting to observe that, whereas all display questions are convergent, referential questions may be either convergent or divergent.
我们发现一个有趣的现象，即尽管所有展示型问题都是聚合型问题，但是参考型问题可以使聚合也可以是发散的。
Majority of teacher's questions are seeking for confirmation, but no referential questions and usually learners' respond with "yes" or repeat after teacher;
大多数老师的问题是寻找证实，但是没有参考性提问，学生解答通常用“是”或跟着老师；
This implies that we should consider increasing the use of referential (real) questions, and of divergent questions in class.
这可以说明我们在课上，应该多使用参考(真实)型和发散型问题。
The Relationship Analysis results in a detailed output showing the referential integrity of key identifiers and the consistency (or redundancy) of domains. It should answer the following questions.
关系分析产生一个详细的输出，显示键标识符的引用完整性和域的一致性(或冗余)。
