The complete interpretation of the textbook, as a synchronous teaching aid, will be revised every year, because the reprint needs a certain revision rate. For example, changing the new question types and redistributing the proportion of key knowledge according to the annual syllabus and examination requirements, if the text of the textbook is changed, the whole chapter will be changed, which is more common in Chinese.

In addition to the above, there have been great changes this year. For example, there is a knowledge structure diagram in front of the previous book, and now it is Xueba notes, which is a summary of the test sites of the whole textbook.

Then there is the section inside, because Baidu can't post a website to say a link, so it can't watch the e-book display, so I cut a few pictures for comparison.

After adjusting the chapters inside, the left and right examples in the left and right columns can be completely corresponding, which is easy to read.

At the bottom of each page, some famous sayings, epigrams and small knowledge points are added to expand reading. The following exercises are divided into two parts: academic examination and college entrance examination, aiming at the detection of different levels of college entrance examination and college entrance examination.

Then there is the answer. The answer of the title itself and the answer of the after-school exercises corresponding to the textbook are set into a booklet.

There are also some concepts such as module setting and ability improvement, such as "525", which is explained on the cover, and you will know what it means corresponding to the contents in the book.
