There is a CD in the back of the book I bought, and there is an activation code in the CD. If it belongs to the school computer room and the school purchases it in a unified way, ask the school administrator. The activation code can only be used once, and repeated use is invalid, so you must have that new book. Advanced teaching concept: the teaching process is fully considered in the compilation of teaching materials, the innovation of teaching content, teaching mode, teaching methods and teaching means is emphasized, the principle of classified guidance and individualized teaching is followed, and the combination of classroom teaching and autonomous learning is advocated to improve language ability and cultivate learning strategies.

English:

English is a branch of West Germanic language, which was first used by Britain in the Middle Ages and became the most widely used language in the world because of its huge colony. The Anglo tribe, the ancestor of the British, is one of the Germanic tribes that later moved to the island of Great Britain and were called England. Both names come from Angeria in the Baltic Peninsula. This language is closely related to Frisian and Lower Saxon, and its vocabulary is influenced by other Germanic languages, especially Nordic languages, and it is mainly written in Latin and French.
