How the people of the whole country are acting in the drought in the south

This is a broad but sharp question.

There is no doubt about the cohesion of the Chinese people, as can be seen from the Wenchuan** and the floods in the south.

First of all, what we can do as individuals is to save water, contribute, and be prepared for danger in times of peace. Because I don't know the cycles and characteristics of climatic and geological disasters. Now all major ** have relevant links to donations, such as: Red Cross, NetEase, Netlink Alipay and Tenpay.

Secondly, the state and local governments should intervene, mobilize materials, and invest manpower, material and financial resources to care for the people in the disaster areas. We call on the people of all ethnic groups across the country to contribute their love to the compatriots suffering from the drought and at least ensure normal drinking water.

Thirdly, the relevant institutions and units of national disaster prevention and control should attach great importance to the climatic and geological disasters such as floods, droughts, and snowstorms that have occurred in recent years, so as to prevent them from happening. Study the underlying causes behind disasters. For example, climate anomalies, the influence of the subtropical high, and the atmospheric circulation in the Indian Ocean.

Finally, schools, schools, and schools should carry out charity activities. Promote water conservation and care for the environment.

Because in the blood, everyone is the motherland.

Donate, donate, do what you can, save water, don't overdraw the resources of our future generations, if you have Alipay or Tenpay, you can donate to the Red Cross Society of China.

1. Donate, disaster relief, and help the people in the disaster area; 2. Start from yourself, start from small things, protect the environment, care for water resources, and save water. 3. Fight against the phenomenon of environmental pollution.

Effective measures should be taken.

Be prepared for danger in times of peace, and prepare plenty of water to prevent drought**.

Drought is a natural disaster that is prone to occur during the non-rainy season. Therefore, during the rainy season, we should take measures to store water and open the reservoir. In normal times, it is necessary to plant more trees and forests to prevent desertification of the land.

The first thing is to protect the environment, but also to increase the vegetation cover, and at the same time people to stop littering and to conserve water.

If you want to prevent drought**, then the local authorities should be prepared, according to the weather conditions, you can manually carry out rainfall, and you can also use some water trucks to help some people in need.

In fact, it is also possible to make a ** of the climate of the whole country in advance, and the analysis in place can also be prevented in advance.

When taking a shower, drench it from head to toe with a spray head, then scrub your whole body with soap or body soap and rinse off one last time. When washing your face and brushing your teeth, try to use a basin and a cup, and don't let the faucet run loudly.

Wash when the washing machine is full of clothes. Also, save the water from the last rinse as the washing water for the next batch of clothes.

If you feel that the toilet tank is too large, you can put a full Coke bottle in the tank to reduce the amount of water you need to flush each time.

Try to use more than one water. Wash dishes and chopsticks with rice washing water and boiling noodle water, which not only removes oil but also saves water; Use vegetable washing water, laundry water, and dishwashing water to water flowers and wash cars; After using the face wash, you can wash your feet and flush the toilet.

When washing your hands, washing in a basin is more water-efficient than washing with a long stream of water, and the same is true when washing vegetables and fruits or washing dishes. Used water can be stored and reused.

The washing machine in the family consumes a lot of water, and in order to save water, manufacturers and researchers have made great efforts to save water as much as possible on the premise of ensuring that the clothes are clean.

Not a flood? Drought began again???

1) The amount of water discharged by A can be calculated from the decrease of water in 5 days from the image of function A;

2) The first rise can be seen from the image, after 10 days, the water storage of reservoir B begins to increase, and the coordinates of point A are obtained from the analytic formula of the function of the straight line ab, and the water storage capacity of reservoir B at this time is obtained.

3) The analytic formula of the linear AD requires the coordinates of point D, and the discharge volume of A is the water inflow of B, then the abscissa of D is 15, and the ordinate of D is 15 according to the equivalent relationship "the water storage of B after 15 days = the original water volume of 10 days + the amount of water injected by A - the amount of water discharged by itself" is calculated from the ordinate of point D, and then the analytical formula of the function is found Answer: Solution: (1) The daily discharge of reservoir A is (3000-1000) 5=400 (10,000 meters for 3 days).

2) On the 10th day, the water from reservoir A will be injected into reservoir B.

Let the analytic formula of the straight line ab be: y=kx+b b(0,800),c(5,550).

b=800 5k+b=550

k=-50 b=800

The analytic formula of the straight line ab is: yab = -50x+800

When x=10, y=300 The storage capacity of reservoir B is 300 (10,000 m3).

3) The amount of water discharged from reservoir A is the same as that of reservoir B at the same time, and the loss of land is not counted.

The intake time of reservoir B is 5 days.

The storage capacity of reservoir B after 15 days is: 300 + (3000-1000) - 50 5 = 2050 (10,000 m3).

a（0，300），d（15，2050）

Let the analytic formula of the straight line ab be: y=k1x+b1 10k1+b1=300 15k1+b1=2050

k1=350 b1=-3200

The analytic formula of the linear ad is: yad=350x-3200
