A: This is something I've never seen. What is it used for?

B: It's used for water. It helps my family use only half as much water as we used to.

A: Wow, that's great! Where can I buy one?

B: You can't get one . Because my father invented it .

A: Really? Your father must be very creative then.

B: Yes. And he believes that water is important. He says we should do something to save water. How do you save water?

A: Well, I save water using shower water to clean the toilet.

B: That good. I think I'll do the same thing as you later.

    Nowadays we can see more and more electric bikes in the street. Electric bikes (be) easy to ride. They run fast and make no (pollute). They become very popular, the electric bikes also cause more traffic accidents. So China plans (make) a new rule for the electric bike riders. If an electric bike is than 40 kilos and can go faster than 20 kilometers an hour, its rider must get a license. It means riders have to pass driving tests before they ride (them) electric bikes on the road.

    People have different ideas after (hear) the plan. Some welcome the plan. A bus driver said happily," a good plan! I think it will make the street much safer." Some are not happy with the new rule at all. One rider said sadly," I don't want to get a license. That's not convenient me to get one." Some don't care about it. A young rider said calmly, "I prefer to use sharing- bikes are popular in many big cities of China now. I hope they can come to Loud earlier!"

We must walk or take the bus to work to air pollution.
