暂时没想好怎么说英语

That's okay! It can be intimidating to speak a language that you're not completely comfortable with, but it's important to remember that everyone makes mistakes and that the most important thing is to just try your best.
Here are a few tips that might help:
Practice speaking English as much as possible, even if it's just to yourself. The more you practice, the more comfortable you'll become.
Use resources like dictionaries, translation apps, or language learning apps to help you find the right words and phrases.
Don't be afraid to ask for help or clarification if you don't understand something. It's better to ask than to try to guess and risk making a mistake.
Be patient with yourself. Learning a new language takes time and effort, so don't get discouraged if you don't see progress right away. Just keep practicing and you'll get there eventually.
I hope these tips are helpful! If you have any other questions, please don't hesitate to ask.
