Add a black English book, whose name is forgotten. It's black, and the bookstore will definitely have it. The grammar in this book is very complete, sometimes the grammar in the grammar book is very complete, and sometimes there are grammars that are not tested in the simulation questions. Very suitable for single grammar breakthrough, very comprehensive and the number of questions is absolutely enough.

If you can't do it, I can give you all the answers, only grammar questions, especially single choice and correction.

Mathematics is hard to buy, just do the basic questions, and the college entrance examination must be above 100. Remember not to be too difficult.
