Dear Jennifer,

    Thanks for your letter. In your letter, you ask me what subjects we like best. There are differences between boys' and girls' favorite subjects in school. Many young girls like math, music, and languages (语言). Most young boys like physical education. But many sixteen-year-old boys like science and math. Many sixteen-year-old girls like foreign language, but science and math is not their favorite subjects. Why do girls and boys have different favorite subjects? We don't know.

—English.
