There are no grammatical errors in my English writing, but I often make mistakes when speaking English. What should I do?

1. Do more reading and memorize more articles. Develop English thinking instead of translating while thinking, and don’t be nervous when speaking.

2. Write down the summary first. If necessary, memorize it and remember it.

3. Correct bad habits in spoken language, such as confusion between "he" and "she", do not use the plural for the third person, forget to conjugate verbs in sentences that are not present tense...

4. Speak bravely and don’t be afraid of being wrong. If you are timid, you can talk to yourself. If you have the chance, speak more English and don't care about other people's jokes. It is better to be laughed at now than later. What's more, many people are not necessarily better than you.
