Firstly, the function of sentences in different positions in the text is clarified from the structure:
1, the first sentence-leads to the full text, outlines, leads to the following, paving the way for the back-* *;
2, the last sentence-summary of the full text, deepen the theme, take into account the above, echo before and after, meaning endless, memorable.
3, into a sentence-connecting the preceding with the following, transition, undertaking the above, leading to the following;
4. Central sentence-point out the center and reveal the main idea;
5, the finishing touch-point out the center of the full text and lead the full text; The sentence is profound, thought-provoking and enlightening after reading.
6, emotional sentences-express strong inner feelings, express your chest directly;
7. Contradictory sentence-it is self-contradictory literally, but the author has profound meaning. Reveal profound connotations and express profound opinions.
There are several common types: parallel type, progressive type (in-depth type at different levels) and total type: (total-subtotal, total-subtotal, subtotal).
In fact, you can use any structure you want when writing a composition. It mainly depends on what kind of article you want to write and how you are going to write it. When teaching children to write, sunshine will not dictate what structure they must use in writing, nor will it teach them how to write. By guiding children's interest in writing and dispersing their thinking, children can write different compositions according to their own ideas. "
