Please help with the study method problem and ask for advice on the study problem

First of all, there are many differences between high school and junior high school learning, and it can basically be said that they have been restarted, such as mathematics, and the connection with junior high school is not so big. So bad grades in junior high school don't mean that high school continues to be scum, as long as you are willing to work hard, nothing is impossible.

With only one week left, you can pick the more important subjects. But the effect of self-study is not so good, sometimes reading the textbook many times is not as good as the teacher's summary and sublimation, so it is not a wise choice to preview too much and become a fat person in one bite.

If the English in junior high school is relatively weak, it is recommended to memorize more words, vocabulary is very important. At the same time, you can take a look at more literary books, now that Chinese is paying more and more attention to literary literacy, and reading some classics is essential, such as "Dream of Red Mansions". In mathematics, the first chapter should be sets, which are relatively simple compared to functions, so after understanding sets a little, you can do some function-related problems, and then summarize them yourself.

In politics and history, I think we still pay attention to the content of the teacher's lectures, and you can watch some documentaries.

Physicochemical biology can memorize basic concepts and formulas or something, but as a liberal arts student, I really don't know much about this, sorry.

Basics: Learn the simple.

I think you can still enjoy your current vacation, the main problem of the first year of high school is the problem of the connection of teaching materials, the things learned are obviously different from junior high school, of course, the biggest difference is the difference in thinking, the first year of high school, you can't learn anything that has a significant impact on the third year of high school, the most important thing is to enjoy the life and experience of the first year of high school, and find the basic ideas and principles of each subject, probably that is, what is the type of college entrance examination question in a certain subject, how to answer in order to give points, what are the methods and rules of answering questions in a certain subject, This is best to form a system in the first year of high school, and the real system is formed in the second year of high school at the latest, and the third year of high school is the practice of finding loopholes and learning some individual questions.

If you study literature, it's good to memorize things in the second semester of the second semester of high school, and the first year of high school should be regarded as quality education, and you know some basic worldviews and concepts. Theoretically, the things in the first year of high school will be a little uncomfortable, but you still have to adapt, although the requirements are not high, but every concept must be understood and analyzed.

Something like this.

1.The kilopascal unit of pressure is a thousand times the SIU of pressure pa-pascal, the unit of pressure. 1kPa (kilopascals) = 1000pa

2.The freezing point is the temperature at which the crystalline solidifies, and different crystals have different freezing points. At a certain pressure, the freezing point of any crystal is the same as its melting point.

With the same crystal, the freezing point is related to the pressure. The freezing point of crystals that expand in volume during solidification decreases with the increase of pressure. When solidifying, the freezing point of crystals that shrink in volume increases with increasing pressure. During the solidification process, the liquid transforms into a solid while emitting heat.

So the temperature of the substance will be in the liquid state when it is higher than the melting point; When it is below the melting point, it is in a solid state. Amorphous substances have no freezing point. The higher the concentration of liquid-solid coexistence, the lower the freezing point The process by which a liquid becomes a solid is called solidification The freezing point refers to a temperature at which the liquid will tremble and gradually become a solid.

The freezing point of various liquids is not the same. The freezing point of alcohol is , and when the temperature is below , alcohol is solid. The freezing point of mercury is:

Kerosene has a freezing point of less than -30. The freezing point of water is 0°

4.Smell refers to the taste perceived by the sense of smell.

K for thousand, and pa for Pa (a unit of pressure). The freezing point refers to the temperature at which the liquid dust wheel becomes a solid, such as the freezing point of water is 0 degrees Celsius. Sodium hydroxide is NaOH. Nahuai smell is perceived through smell, and taste is perceived through tasting.
