Learning strategies: use the right language. A nation's culture exists in its language. It's not enough to know the right grammar. It's also important to know how to choose the right language for each occasion
Can you lend me your pen?
Asking for information or help is a very common and necessary activity, especially when we visit a foreign country. Therefore, it is very important to know how to make a request politely, But sometimes it's not enough. We need to learn how to be polite when we ask
Like Chinese, in English, we talk to different people in different ways. The expression you use depends on who you talk to or how familiar I am with them. If you say to your teacher, "where's my book?" it sounds rude. But if you say, "excuse me, Mr. West, Do you know where my book is? "Your question sounds much more polite. On the other hand, in some situations, it's OK for someone who is very familiar with you to say," where's my book? "
And you don't usually say, "Peter, lend me your pen!" a very direct command like this in English sounds rude. Usually polite questions in English are long, including extra words like, "please Or: "can I ask "Peter, lend me my pen, will you?" sounds more polite. Sometimes we may even need to spend more time before making a request. For example, if you meet a stranger on the road, we should say, "excuse me, I want to know if you can help me" or "I'm sorry to disturb you, but …”
It seems that speaking politely is more difficult than expressing directly, and it's true to some extent. However, in order not to take the risk, learning about language etiquette is just as important as learning grammar or vocabulary. And doing so also helps you to master English better, or any other language you want to speak
3A 1. "Where is the public toilet?" 2. "I want to go to the library. Where is it?" 3. "How much is that football?"
3b 1. A teenager wants to stay out late and ask his parents about it. 2. A foreign friend is interested in your new dictionary and asks about it. 3. Some students want to hand in their homework later than the teacher asks. 4. You want to change the time when you invite a friend to your home for dinner

Living, working, learning and playing? Robert Qian, a Chinese Canadian, already has. Now in China, he finds that his family is like a tall tree with long roots
Robert is a young overseas Chinese who came to visit his ancestral home as part of the search Roots summer camp program. The program was initiated by the local government of Guangdong Province. The program started in 1980 and has so far enabled thousands of overseas Chinese students to find their family roots. Young people are usually 16 to 25 years old. At most, like Robert, it is difficult to speak Chinese, I have never been to China before
During the two-week camp, they learn Chinese culture, see the changes taking place in the area, and visit the scenic spots of interest. Taking their ancestral village is often the most exciting part of the trip, The villagers look at their daily activities
Katie chin, a young American student, said, "thanks for looking for roots, I began to understand my Chinese roots, and who I am. It was a great trip and I had so many memories to take with me“
The leaders of the program firmly believe in the program and say its aim is to give young overseas Chinese a chance to learn more about themselves. "I really like traveling," Robert said so far. "It's a big step and I'm looking forward to getting more about my roots here

If the function image passes through points (1,2), find the function image after translation
The analytic formula of the first question: y = - 2X-4
It is known that y is positively proportional to x + 2, and when x = 1, y = - 6
(1) Find the functional relationship between Y and X
(2) If the function image passes through points (1,2), find the analytic expression of the function after translation

1/2 = k/4
So k = 2
B(2,1)
The slope of the first-order function after translation is still 1 and passes through point B
So the linear function after translation is y '= X-1
So the coordinate of the intersection of the image of the first-order function after translation and the x-axis is (1,0)

If the surface area of a cuboid is 130 square centimeters, the bottom area is 20 square centimeters, and the perimeter of the bottom surface is 18 centimeters, how many cubic centimeters is its area?
''''''''''''''''''

Let length be a, width B and height C
2*（a+b）=18
a*b=20
2*(a*b+b*c+a*c)=130
The results are: a = 5, B = 4, C = 5
Volume = a * b * C = 100

Let a (2.0) be a certain point on the plane, and the graph of moving point P (sin (2t-60 °), cos (2t-60 °) be c,
When t changes from 30 ° to 45 ° find the area of line AP sweeping graph C

The graph C of moving point P (sin (2t-60 °), cos (2t-60 °) is a circle: x ^ 2 + y ^ 2 = 1
When t = 30 ° P is at P1 (0,1),
When t = 45 °, P is located at P2 (1 / 2, √ 3 / 2), and P2a is tangent to the circle;
So the part of line AP that sweeps through figure C is an arch

How many square meters is one ton of 0.8mm thick copper plate equal to?

V=m/ρ=1000kg/8900kg/m3=0.112m3 h=0.8mm=0.8*10 -4m S=V/h=0.112m3/0.8*10 -4=140m2

The circumference of the rectangle is 36cm. If the length is reduced by 4cm and the width is increased by 2cm, the rectangle will become a square. If the original length is xcm, the equation is ()
Dear friends, as long as the equation, not the result! This morning we just finished the final exam. What I wrote was, but some other students said X + 4 = 36 / 2-x + 2. What should I do? I've made this kind of mistake several times. I've come here to check it carefully several times. Alas
I wrote x + 4 = 18-x + 2

After the simplification of other students' x + 4 = 36 / 2-x + 2, your equation x + 4 = 18-x + 2 is the same
Don't worry, you will get good results and have confidence in yourself!

It is known that hyperbola y = K / X and parabola y = ax ^ 2 + BX + C intersect at three points a (2,3) B (m, 2) C (- 3, n)
1. Find the analytic formula of hyperbola and parabola
2. Point a, point B, point C in the plane rectangular coordinate system, and calculate the area of △ ABC

1. Substituting a into hyperbola y = K / X3 = K / 2K = 6, the analytic formula of hyperbola is: y = 6 / x, substituting two points of BC into hyperbola, we can get two-point coordinates. 2 = 6 / m m m = 3B (3,2) n = 6 / (- 3) n = - 3C (- 3, - 2) substituting ABC into parabola 3 = 4A + 2B + C2 = 9A + 3B + C-2 = 9a-3b + Ca = - 1 / 3B = 2 / 3C = 3, the analytic formula of parabola is: y = - 1 / 3
