Systematic grammar learning can deepen students' understanding of the target language, consolidate students' language knowledge and lay a good foundation for the language, which is conducive to improving students' ability to use English.

Students can not only broaden their horizons, but also increase their knowledge in the long-term reading process, thus improving their reading ability. More importantly, reading can cultivate students' ability to analyze and solve problems, which is conducive to students' strong self-study ability.
