Early to bed, early to rise, makes a man healthy, wealthy and wise.
This is an old English saying. Do you know it before It says that we must go to bed early and get up early in the morning. Then we should be healthy. We should also be rich (wealthy) and clever (wise).

The body also needs exercise. Walking, running, jumping, swimming and playing games are all exercise. Exercise keeps the body strong.
Exercise also keeps the blood (血液) moving around inside the body. This is very important. Our blood takes food to all parts of our body. The head also needs blood. Exercise helps us to think better!

I'm sure you all know how important recycling is. Recycling is when you take old things and turn them into new things. It sounds like magic. But it's actually very scientific.
Material The first thing you have to do is to collect items that can be recycled. Only certain materials can be recycled. These include things made out of paper, metal, glass and plastic.
Daily things Can you think of everyday items made of these materials Soda cans are a good example. They are made out of metal. Magazines and newspaper are made out of paper. So are cereal boxes. Some bottles of juice are made out of glass. Bags and yogurt containers are made out of plastic. There are many things that can be recycled.
Loop These things are usually stamped with the recycling loop. It has 3 arrows that go in a triangular (三角形) circle. This shows that cycle (循环) continues. Items are thrown away but continue their lives as something else.
Process Let's go back to the process of recycling. ①The items are put in a recycling bin. ②A truck carries the items to a recycling plant. ③The materials are separated and squashed (被压扁成) into square cubes. ④Companies buy and turn them into new products.
19. What is "recycling" according to the passage

How can we protect the Earth One problem to solve is climate (气候) change. You might wonder about climate change. What is it, exactly
Gases surround the Earth. _____24_____ Sunlight passes down through the gases. The gases trap (储存) the sun's heat and act like a blanket. Without these gases, the Earth would be very cold. The trouble comes when humans add too many gases to the atmosphere. The gases build up and trap even more heat. This causes changes in climate. The Earth becomes too warm.
_____25_____ There's another gas causing climate change. No one talks about it as much. It is nitrous oxide (氧化亚氮). Many call it laughing gas. Dentists may give patients nitrous oxide so they will not feel pain. The atmosphere has small amounts of nitrous oxide. But nitrous oxide can stay in the atmosphere more than 100 years which can change the climate a lot.
Nitrous oxide forms naturally. _____26_____ Bacteria are living organisms (生物) made of single cells. Farmers use nitrogen fertilizer (氮肥) to help grow bigger crops. The bacteria in the soil take the nitrogen from the fertilizer and make more nitrous oxide with it.
So how can we help "Number one is to not waste food," Wagner Riddle, a scientist from Canada, said. _____27_____ That number comes from a U. S. university study. "There is a lot that goes into making food", Wagner Riddle says. "So then if it's wasted, it's for nothing."
24. A.That's the reason for climate change.
B.It comes from bacteria (细菌) that live in the dirt.
C.Carbon dioxide (二氧化碳) is one gas that traps heat.
D.More than one-third of all food created in the U. S. is wasted.
E.These gases reach high into the sky and are called the atmosphere (大气层).
25. A.That's the reason for climate change.

四、阅读理解-阅读回答问题（共1小题；共8分）
Once upon a time, there was a king who had gone to visit neighboring kingdoms. He was gifted a pair of baby parrots by the king of the last kingdom where he was visiting. They were the most beautiful birds that he had ever seen. So, after returning to his kingdom, he called for a bird trainer and asked him to train parrots.
The king also set up a place in the palace garden for the parrots. He often looked at them from his palace window. As time passed, one day the trainer came to the palace and told the king that though one of the parrots was flying high in the sky, the other one was not moving from its branch since the day it had arrived.
When hearing this, the king summoned the best trainer from all his land and the nearby kingdoms. They came quickly and tried their best, but none of them could make the parrot fly! He even asked his courtiers to try to find a good way to make the parrot fly but they all failed. The parrot was not moving from his branch at all. Finally, after trying everything, the king thought to himself: "Perhaps I need someone who may be more familiar with natural habitat." He asked his courtier to get a farmer from the countryside and take him to the parrot to see if he could understand the problem with the parrot.
The next morning, the king was surprised to see the parrot flying high above the palace gardens. He asked his servant to call that farmer to meet him. The servant quickly went and found the farmer. The farmer came and stood before the king. The king asked him, "How did you make the parrot fly " With his hands folded with respect, the farmer said to the king, "It was very easy. I just cut the branch where the bird was sitting."
28. ( )Why did the king like the parrots so much
A. Because they could talk to him.
