You can watch more English news on CCTV9. . Try to understand English movies without Chinese subtitles. . You can practice by watching BBC press releases every day. . This is English, mainly a matter of interest. As for science, I think doing problems is the key. For weak disciplines, sort out the knowledge structure and fill the loopholes. The connection between junior high school and senior high school is very important. Many junior high school students think differently. It is very helpful for senior high school students to exercise logical thinking. Thank you.
