Water is very important for us. We should try our best to save water in many ways. Here are some tips for you. First, turn off the tap. Just turn off the tap while you brush your teeth in the morning and before bedtime. The same is true when you wash dishes. Second, save water when taking a shower. To save even more water, keep your shower under five minutes long. Put a clock in the bathroom when you want to take a shower next time. Third, water your garden at a good time.The best time to water your garden is in the early morning or late evening when it’s cool outside. Watering when it’s hot and sunny is wasteful because most of the water disappears before the
plants have time to drink it.
