阅读下面一篇短文,判断下列句子是否符合短文内容,符合的用“A”表示,不符合的用“B”表示。

     Clean water is not only important for people to produce food, but necessary for our life. However, many

people in Asia and Africa don't have enough clean water to use. The World Health Organization reports that

almost 4,000 children die each day of dirty water or lack (缺乏) of water.

     Farmers use 70-85% of the world fresh water to produce food. People usually don't pay much attention to

how much water industry (工业) uses, but you may be surprised to know that industry uses 59% of the water

in developed countries.

     Home use takes up (占据) only 8% in the world. But as cities grow, more water will be used. The local

government has to try to make people use less water.

     In 60% of European cities, people are saving water by using less. They even keep waste wafer for other

use. In Australia, the government has encouraged people to collect rainwater and recycle water from showers

for a second use.

     The US Environmental Protection Agency has made a water saving program to encourage families and

businesses to check their water use and save more water. Scientists and the UN are looking for good water

management as the key to solving the problem. We can all work together to protect our fresh water in our

daily life.

( )1. In developed countries, most water is used by industry.
