Basically the teacher is explaining the contents of the book.

Sometimes I do listening exercises.

English learning content:

Besides the books and listening exercises, there is also grammar.

Grammar learning content:

tense

Gerund and noun. infinitive

Interrogative words+infinitive

Indirect interrogative sentence

conjunction

Comparative amount

Indefinite pronoun

Nouns without articles

Conditional sentence (type 0-3)

modal verb

The learning content of mathematics:

1. rational number and irrational number (if any number can be written as a fraction of a/b, where a and b are integers and b is not equal to 0, then this number is called rational number; A number system that cannot be expressed by a fraction is called an irrational number.

2. Law of Integer Exponent (Positive Integer Exponent, Zero Exponent and Negative Integer Exponent, Counting System and Binary and Hexadecimal Numbers)

3. Approximation and error (the concept of significant figures, the meaning and understanding of scientific notation, and the calculation of various errors)

4. The application of trigonometric ratio and triangle (1) (using sin, cos and tan to find the angle, gauge and moment of triangle, and the application of sine, cosine and tangent of acute angle θ)

5. Area and volume (find the volume and surface area of pyramid, cone and sphere, compare and distinguish the dimensions of length, area and volume, line segments corresponding to similar solids, the ratio of corresponding area to volume and the relationship between them).

6. Measurement of concentration trend (find the average, median, mode and mode array from a set of established non-grouped data or grouped data; Comparison of average values, construction of data sets by using average values, application of average values, etc. )

7. Binary linear equation (learn simultaneous binary linear equation, substitution method, elimination method and the application of simultaneous equation, etc. )

8. Unary linear inequality (learning unary linear inequality, number line and inequality and the application of inequality, etc.). )

9. Quadrilateral (learn the definition, midpoint theorem and tangent theorem of parallelogram, rectangle, diamond and square)

10. Coordinate geometry of straight lines (learn the distance formula between any two points on the coordinate plane, the concept and formula of slope, the slope relationship between parallel lines and vertical lines, the intercept formula and the midpoint formula of line segments).

1 1. trigonometric ratio and application of trigonometry (2) (learn to express trigonometric ratios of special angles such as 30, 45 and 60 with roots, find trigonometric ratios with right triangles, and operate by using the relationship of trigonometric ratios. The problems related to trigonometric ratios include slope, elevation angle and depression angle, and azimuth angle on the plane, including compass azimuth angle and true azimuth angle).

12. Simple concept of probability (learn the meaning and application of probability, analyze the possible results of random events, so as to find out the differences and connections among probability, theoretical probability and experimental probability, and calculate the meaning of theoretical probability and expected value by listing all possible results and numbers)
