We use it in many ways. In our daily life, we need 31 (drink) water to stay healthy. But do you know how much water we should drink every day? A lot of people think they should drink eight glasses of water a day. But in fact, the amount of water we need 32 (depend) on many factors, such as our age, weight and activity level. For example, if you are very active and do a lot of sports, you need 33 (drink) more water. You should also drink more water in hot weather. However, not everyone has enough clean water 34 (use). In some places, water is very scarce. People there don’t have 35 (much) water for daily use. We should save water. We can start from small things. For example, when we brush our teeth, we should turn 36 the tap. We can also use 37 (reuse) water to water plants. In addition, water pollution is a big problem. Factories and farms often put 38 (harm) chemicals into rivers and lakes. This makes the water undrinkable. We need to protect water resources and stop 39 (pollute) water.
