Unit8 A green world Task Reading test In most situations, light helps us to see. But nowadays humans are using too much of it so that it is in fact a kind of pollution. According to scientific research, about 2,500 stars can be seen by the human eyes without any special equipment (装备). But because of light pollution, you can only see 200 to 300 stars from today’s countryside, and no more than ten stars from a city. Light pollution affects more than just our view of sky. Research shows that lots of night-time light can harm wildlife, too. When birds fly to another place over cities, they sometimes get lost by the brightness and fly in circles until they drop from tiredness. Sea tortoises need dark beaches for laying eggs, but they can’t find their ideal places because of those bright lights. Too much light at night may even affect human health, but scientists are not sure of that. They are still learning more. ( )How many threats(威胁) of light pollution are mentioned in the passage?

Recycling is a great way to save energy, space and money. Many things can be recycled, such as glass, plastic, old clothes and shoes. However, we must remember that recycling is not the only way to protect the environment. For example, we can save energy by turning off the tap when we brush our teeth and taking shorter showers. We can also save water by reusing it if possible. It is important for us to take our own shopping bags to the supermarket and use reusable bottles for drinks. Moreover, if we always remember to turn off the lights when we leave a room and turn off the power when our TV or computer is not in use, we can save a lot of energy. It is time for us to take action to make the Earth a better place. So I really hope to join you. Further thinking Have you made up your mind to protect the earth?
