Is that how the question works? What should I do when it comes to the question?

Reading the map, it can be seen that (1) the project is to transport natural gas from the Tarim Basin of Xinjiang Uygur Autonomous Region to the middle and lower reaches of the Yangtze River through pipelines, and the end point of the "eastward transmission" is Shanghai (2) The topographic areas through which the project passes include the Tarim Basin, the Hexi Corridor, the Loess Plateau, the North China Plain, and the middle and lower reaches of the Yangtze River Plain The project crosses the Yellow River three times and crosses the Yangtze River once, and the amount of work is very arduous However, the construction area of 28 meters wide is strictly stipulated during the construction process, and its purpose is to protect the ecological environment along the line (3) The project is divided into south, north, The terminus of the southern line of the three transmission lines is the Pearl River Delta Industrial Base (4) The project is a south-to-north water diversion project, which mainly transfers water from the Yangtze River to the northwest and north China regions where water is scarce (5) The railway in the project is the Qinghai-Tibet Railway According to the title

Therefore, the answer is: (1) Xinjiang Uyghur; Tarim; Natural gas; Shanghai; (2) Hexi; Loess; North; Yellow; protect the ecological environment along the route; (3) Pearl River Delta; (4) South-to-North Water Diversion; Yangtze; (5) Qinghai-Tibet

No, the final empty space is not 1:19, but 1:9.

Many, many are not long or short&i, they all tell me that the holiday Phoenix City V second bureau is crapped.

Calculate the x value of the intersection of the two lines first:

y1 = y2

x^2 + 2 = -(x-1)^2

x = 1/2

According to the title, the shadow area is made up of two parts.

Part I: Is the part of x from 1 2 to 1 S1 = (y2-y1) on x (1 2,1) Part II: is the part of the calculation of the value of x corresponding to x from 1 to y2 = 0:

y2 = -(x-1) 2 + 2 = 0x = 1 + root number 2

s2 = the final shadow area of the integration of y2 on x (1,1 + root number 2) = s1+s2

Diagnosis. Wrong.

**。The laws of arithmetic are not clear.

If the single digit is not wise enough to reduce the ruler, it should be reduced from the top ten to the top one. **。

2 Calculation method. 22-18=4, a gap of 4 squares.

The cat jumps 3 squares once, the mouse jumps 2 squares once, 1 more square, and each time the gap narrows by 1 square to catch up with the mouse, it actually makes the gap 4 squares become 0, which takes 4 times.

Starting from cat 22, you need to jump to the position of 22-(3 4)=10.

The mouse is 4 blocks in front of the cat.

The cat jumps 1 block more than the mouse at a time.

So, after 4 jumps, I caught up.

At this time, it is 22-3 4 = 22-12 = 10
