An introduction is just an introduction, and it better be good.

Absurd and irrelevant, not only will it not lead students into the text, but it will become the interference information of teaching.

2, blind and random, lack of purpose

I don't understand the textbook, the intention of the editor, the teaching value of teaching, and the learning situation, which leads to the arbitrary and rough design.

3, old-fashioned, dull and boring

The lead should be as novel and interesting as possible, reasonable and unexpected.

Simply instruct students to "turn to a page" and "let's learn a lesson", and students will get bored over time.

4. Too big and improper, but not advanced.

This kind of guidance often States a teaching goal to students in general, which makes them confused and at a loss.

5. The teacher sings solo, usurping the host's role.

Teachers are broad-minded and endless, trying to exaggerate things, which gives leaders many unbearable functions and virtually ignores the existence of students.

cite

The opening remarks can also directly quote other people's words to pave the way for your speech and set off the theme.

As a material cited in the introduction, there are generally two basic conditions:

First, the cited materials have strong generality, persuasiveness and appeal.

Secondly, the quoted materials come from authorities, celebrities or people familiar to the audience, and the speaker uses the authority effect or the relatives and friends effect to attract the attention of the audience.

In some cases, the speaker doesn't even need to explain the source of the quoted material.
