yī lǎng伊朗xià tiān夏天hěn很rè热，shuǐ水wēi jī危机biàn变yán zhòng严重
This summer, the weather in Iran is very hot, and many places have power outages.
The government has closed some public offices and may declare a nationwide week-long holiday to save electricity.
Many places in Iran are experiencing water shortages, especially the capital Tehran and Alborz Province, where water is the scarcest.
The water in reservoirs is much less than last year.
The government is asking everyone to use less water.
Experts say that if people do not save water, Tehran might experience long periods without water, similar to Hamadan.
Because there is less rain and snow, the snow on the mountains cannot slowly turn into water.
Many people are digging wells to get water, and underground water is decreasing rapidly; in some places, the ground is sinking quickly.
Tehran has many people, and everyone uses too much water, so saving water is very important.
There is currently no good solution to this problem.
If the situation does not change, Tehran may often have water restrictions in the future.
