I have just immigrated to the United States for a month, and I will be a senior one in a few days. My English is not good. What should I do? I will get extra points for my good answer.

Read big books, watch movies and TV series, soon. My daughter went to America at the age of six and a half. For the first three months, she was dizzy and didn't understand. After this stage, she heard that reading and writing are very good. I think it's because she spends a lot of time reading, watching movies and watching TV. This is a shortcut, and we must cultivate a sense of language first. Play with native speakers. Experience things together to learn well in context! Good luck!
