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% 0f the world freshwater 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 useless water. In 60% of European cities, people are saving water by using less. They even keep waste water 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.

    Many years ago, there was a very popular sport in America. Who invented the sport more than 3,000 years ago? We don't know. But everyone thinks it was the Olmecs(奥梅克人）made it popular.

    People don't have the same rules about the game all over the world. People in different parts of the world play the game in different places at different times. If we want to bring back the sport, we need to have two teams of players standing on each end of a court. When the game begins, the two teams need to pass a ball from one side of the court to the other. The players can't touch(触) the ball with their hands and feet. But they can use their elbows(肘) and other parts of their bodies hit it. If a player does not pick up the ball in time and lets it fall to the ground, that team loses a point. But if a player makes the ball through a hoop(环),that team scores a point. The team with the most points wins the game.

    A new App has been used in South Africa to benefit (有助于)the relationship between wildlife and humans.

    Roadwatch, created by the Endangered Wildlife Trust (EWT),is designed to let drivers   record any roadkill they see on the country's highways.

    It may seem like a strange idea, but EWT says that it could become the perfect platform for receiving important information. Information on where endangered species (物种）are living and the danger that they are under from traffic can help to inform decisions on conservation of matters (物质守恒）in the future.

    People can use the App through Facebook, WhatsApp, SMS and Linkedin to report the   species, location, time and date of the creature that has been seen on the road.

    Wendy Collinson field officer at EWT suggested that it could lead to more people taking care on the roads and paying more attention to animals that may be trying to cross the roads. One of the biggest problems is with reptiles (爬行动物）and snakes, which she believes people hit on purpose, as they are generally seen as scary. However, they are important to the health of ecosystems, just as all creatures are and also need to be protected.

    Emily Taylor from EWT said, “Roadkill simply hasn't been studied here. The road ecology and how many endangered species are being killed, is something we need to know more about. We want people to report as much as possible.”

    There have been some other Apps to use in relation to wildlife spotting in South Africa, but most of them are about animals that have not been knocked down, including those helping to collect information of where certain species have been seen, such as in parks.

    Water is very important to us. Every day we drink water, cook with water, take a shower in water, and have many other activities with water. Let's read and learn more about it!

    70percent of an adult's body is water. And about 80percent of a baby's body is water.

    Drinking too much water q{#blank#}1{#/blank#} can cause water intoxication (醉).

People should have about eight c{#blank#}2{#/blank#} of water every day.

    By the time you feel thirsty, your body has l{#blank#}3{#/blank#} over one percent of its water.

    About 80percent of the Earth's surface is covered with water.

    Only one percent of this water is fresh, 97percent is salt water and two percent is f{#blank#}4{#/blank#} in glaciers (冰川).

    And now, it's time to s{#blank#}5{#/blank#} water!
