For example, fatigue vs. fatigue, explosion vs. explosion, reduction vs. reduction, etc.

2. Long complex sentences) vs simple sentences.

For example, "Although the current economy is very strong, some experts predict that a recession is coming."

Form: the economy is quite strong at present; However, some experts predict the coming recession.

Informal: The economy is very strong now, but some experts say we will have a reception soon.

Phrasal verbs vs phrasal verbs, slang, idioms and chat language (slang, idioms and spoken language) are widely used.

We often find that we can study textbooks well, but we just can't understand English in movies and TV plays. Why? Because there are a lot of slang and idioms in movies and TV plays, even if the vocabulary is up to standard, it is still a little difficult to fully understand them. After all, we won't learn this in books.

4. Personal pronouns and passive forms are commonly used, and the first and second personal names and active forms are commonly used.

When writing papers abroad, professors usually ask students to make statements in impersonal or passive forms, and avoid using the first or second person to call me/you/us and active forms. Although these words are widely used in informal language and spoken language, they are usually considered too personal and too casual in formal academic writing. For example:

Official: I believe this problem will be solved in the future.

Informal: We believe this problem will be solved in the future.

5. Avoid abbreviations)+Focus on grammar vs Use abbreviations+Give up perfect grammar.

When using formal English, you should avoid using abbreviations whether you have obsessive-compulsive disorder again or not. For example, in formal papers and exams, commonly used it's must be written as it is. Relatively speaking, informal English likes to communicate with the fastest speed, pays little attention to grammar and does not require perfection. As long as there are no mistakes, the other party can understand and feel free. For example:

Officer: Have you finished your work?

Informal: Have you finished your work?

Officer: Can you help me?

Informal: Help me!
