It's simple. As far as my personal experience is concerned, it is to read more and recite more. To choose what to read and recite, you usually recite some useful and classic sentences, including famous sayings and aphorisms, and some personal comments. More memorization broadens your knowledge. Why did you choose that sentence? Because such sentences are often not very long and easy to recite, they are often remembered in daily life, so they will not be forgotten so quickly. In other words, reciting such sentences will be easier than other sentences.

Another thing is the feeling I have from time to time in my life. Try to translate two or three sentences into English, then take them to the teacher to help me correct them, and then memorize them. This is a very common and practical way to absorb knowledge. This is your own idea, easy to remember. Furthermore, sentences such as feelings are often used in compositions, such as: I think XXX is not good. Personally, it is not good for society. Secondly, it hurts the feelings between people. As long as you translate your similar feelings into English before, what I said above can be applied to your composition as long as you change the similar sentences before. To put it bluntly, English composition and Chinese composition are not much different, they are all a routine, expressing opinions, arguments and endings. Read more model essays, pay attention to methods, and don't just read them. You should find a way to write that proposition according to the requirements of the topic. Just write down the central sentence, then summarize the outline of the model essay and compare the differences between your own outline and the model essay outline.

Pay attention to collocation and common phrases in the model essay. Often some eye-catching sentences must be memorized for their own use, which can make the composition by going up one flight of stairs.

There is also about typos. Don't write wrong words. I would rather use simple words than write disyllabic words that I am not sure about. I think there's nothing more to say. I believe that if you keep practicing like this, the writing level of your composition will not be too bad. Good luck, Jill.
