What are the big grammar items in senior high school English?

1. Nominal clauses (subject, predicative, object and appositive clauses)

2. Attributive clauses (restrictive attributive clauses and non-restrictive attributive clauses)

3. Adverbial clauses (reasons, results, purposes, conditions, concessions, ways, comparative adverbial clauses)

These are the clauses, tenses, parts of speech, etc. Look and collect some information! Baidu, you will get a lot of unexpected things!
