There are not many advanced vocabulary for high school students. Appropriate use can make the composition more outstanding. As for using advanced vocabulary, it is the same as using common vocabulary. Of course, you need to make sure your spelling is correct, otherwise it will be counterproductive. For example, if you want to write about celebrating a holiday, you can use a very direct translation, happily greet, but you can also use a single word, celebrate.

Writing like this is not a very direct translation, but it is more authentic and can naturally show your English skills. By the way, I would like to give you a little suggestion. For high school composition, the first thing you need is correct grammar and spelling. One point will be deducted for every mistake.

Secondly, you can make the article less bland by using some clauses that you are sure to know. This is very simple, just memorize a few more sentences at ordinary times.

The third thing is to use some advanced vocabulary~? 1. Pay attention to using phrases and idioms to replace some words to increase literary talent. For example, use make use of instead of use, use catch sight of instead of see, etc. .Read more articles of the corresponding level, the better if you can memorize them, and the more you read them, you will find that the wording is not advanced, but authentic. 2. Use some very "foreign" words. Such as Thank you for sharing the time with us. (Use share instead of spend)

The way he views the world is very practical. (Use view instead of look at)

The noise nearly drove me mad. (Use drive instead of make)

3. Avoid using the same word or phrase repeatedly. For example, I like reading while my brother enjoys (without likes) watching TV.
