Use it as an illustrative method of comparison to introduce things

Comparison is an explanatory method that compares two kinds of things and phenomena of the same or different categories to illustrate the characteristics of things. Explain some abstract or relatively unfamiliar things, and compare them with concrete or familiar things, so that readers can get a concrete and distinct impression through comparison. The characteristics of things also tend to be revealed in comparisons.

When making comparisons, it can be like the same kind or different comparisons, and things can be "sideways" or "vertical".

7. Comparison is an expository text.

This is an explanatory method that compares two types of things or phenomena that are the same or different in order to illustrate the characteristics of things.

The role is to highlight a certain characteristic of the thing.

Make a comparison expository sentence as follows:

1. "The Sun": "When we look at the sun, we think it's not big, but in fact it's so big that 1.3 million earths can be worth one sun." "Comparing the Earth with the Sun highlights the size of the Sun.

2, "There is Only One Earth": "Compared with the vast universe, the earth is small, it is only so big, it will not grow again." Here we use the technique of comparison to write more vividly that the earth is small.

3. Many people have seen elephants and say that elephants are very big animals. In fact, there is an animal that is much larger than an elephant, and that is the whale.

4. The rain in spring is delicate and soft, and the rain in summer is rough and warm.

Writing ideas: Start by pointing out the item to be introduced, introduce the characteristics of the item (such as color, shape, function, etc., choose one or two of the features to focus on, and use the explanation method appropriately), and write why you like it. In this process, the uniqueness of things is highlighted.

Here's an example: I have a rectangular tin spray stationery box, which is 20 cm long, 5 cm wide and 2 cm high. Except for the pattern, Chinese characters, and English, the rest are light blue, which is beautiful and generous. The delicate pattern on the box surface is even more eye-catching:

The lively little red rabbit was "smiling" at me. There are also some mischievous little oranges, with different expressions: some laughing, some dumbfounded, and some sad faces, which are very funny.

The stationery box is not only realistic and beautiful, but also novel in style and easy to use. If you open the gate of the "Stationery Castle", you will find that there is a lot of stationery including "living".

The box is divided into two layers, the upper layer has a straight pen and a few ordinary pencils, all of which are sharpened and placed there, silently, as if sleeping soundly.

A black triangular watercore pen is also lined up there. Since the words written with a fountain pen cannot be erased with an ordinary eraser, the correction paper has also "joined" the ranks of the "stationery team".

Because this stationery box is not very large, I had to "embed" the correction paper on the lid. Lifting the lower level, the lower layer is divided into several compartments: in the thin and long compartment, there are "lived" mechanical pencils and lead cores; Next to the mechanical pencil are two more "houses" of similar size, the "owners" are the planer and the eraser.

They all "lie" on the ruler in obscurity, motionless, without saying a word, "sleeping sweetly" on the ruler. To the west of their house, there is also a compartment, which is my folder, which is dedicated to holding notices, "small data" and other items.

Yes! Stationery box, you keep my school supplies day after day, year after year, at my service. Thank you and may you spend a wonderful time with me, you will always be my good friend.
