Phrases and key sentence patterns

I'm reviewing by myself

It is a very common topic to ask "how about?" in English, which involves different meanings and sentence patterns. Only by using appropriate sentence patterns to adapt to different meanings, can "authentic" English be embodied
1、 "What (how) about..." can be followed by a noun, gerund or pronoun
I'm going to fly a kite this afternoon.What about you?
I'm going to fly a kite this afternoon. How about you?
What about playing chess now?
2、 To inquire about the present situation of someone or something (such as physical condition, learning condition, etc.), use the sentence pattern "how is (are)..."
How's everything there?
How is everything there?
How's your father?Is he much better now?
How's your father? Is he better now?
3、 To inquire about a person's appearance, morality (especially the objective impression) or weather conditions, use the sentence pattern of "what's... Like..."
What's the weather like today?= How's the weather today?
What's the weather like today?
— What's his mother like?
— She's tall and thin.
What does his mother look like?
She is tall and thin
4、 How do you like
How do you like the cartoon film “Mickey And Mouse”?
What do you think of the cartoon movie "Mickey Mouse and Donald Duck"?
How do you like Hangzhou?
What do you think of Hangzhou?
5、 What do you think of
What do you think of the supergirls?
What do you think of super girls?

Speed. Thank you

I think class listen to the teacher's content, in which the details must be the key. Pay attention to the summary, it is best to prepare an English notebook
come on!

If the parabola y = x2 + BX + C is shifted 3 units to the right and 2 units to the down, the analytic expression of the image is y = x2-3x + 5, then ()
A. b=3，c=7B. b=6，c=3C. b=-9，c=-5D. b=-9，c=21

Y = x2-3x + 5 = (x-32) 2 + 114, move it up 2 units, get y = (x-32) 2 + 194. Then move it left 3 units, get y = (x + 32) 2 + 194 = x2 + 3x + 7. So B = 3, C = 7. So a

Can you tell me the amount of stone per cubic meter of asphalt concrete

It depends on the ratio of asphalt to stone. You can calculate the density, the ratio of asphalt to stone and the content of mineral powder by yourself. The density is about 2500kg / m2. Except 5% asphalt and 8% mineral powder (the content can be changed), it is about 2200kg. The details also depend on these three parameters

Is n-4 / M + n a monomial or a polynomial

N-4 / M + n is a polynomial

A problem of solving the curvilinear integral of high number to coordinate with high score
Solve ∮ XDY YDX, where l is a closed broken line ABCA with vertices a (0,0), B (1,0), C (1,2)

A: Method 1: it is divided into three parts: l = l 1 + L 2 + L 3, where l 1 is y = 0, L 2 is x = 1, L 3 is y = 2x ∮ XDY YDX = ∫ 0 to 10 DX + ∫ 0 to 21 dy + ∫ 0 to 1 XD (2x) - 2xdx = 0 + 2 + 0 = 2. Method 2: Using Green's formula: let P = - y, q = x, then ∮ XDY DX =: ∫ D (δ Q / δ X - δ P / δ y) DXDY = 2 ∫ D

Junior high school physics in the first lesson of length unit conversion [km, m, cm, mm, um, NM] did not understand, ask the teacher to explain

Based on M M
1m=0.001km=100cm=1000mm=1 000 000um=1 000 000 000nm
K = 1km = 1000M
Cm 1cm = 0.1M
Mm = 0.01M
Um micron 1um = 0.000 001m
Nm, nm, 1nm = 0.000m

Multiplicative distributive law, associative law, commutative law, additive associative law, commutative law

Multiplicative distributive law a (B + C) = AB + AC
Association law AB + AC = a (B + C)
Commutative law AB = Ba
Association Law (a + b) + C = a + (B + C)
Commutative law a + B = B + A

A straight line passing through the focus of parabola y = 2px (P > 0) intersects with the parabola. The ordinates of the two intersections are Y1 and Y2 respectively
The square of the parabola y = 2px (P > 0) is the intersection of a straight line on the focus and the parabola. The ordinates of the two intersections are Y1 and Y2 respectively. The proof is: Y1 times the square of y2 = - P

Given that the focus is on the x-axis and is (P / 2,0), then simply let the linear equation: y = K (X-P / 2)
By combining with the parabola y ^ 2 = 2px (P > 0), we get the formula: y ^ 2 = 2p (Y / K + P / 2), and then we know that y1y2 = - P ^ 2 (here according to the Weida theorem ~)
