（Da Wei comes across Li Lei, who is studying, in the school library.）
A: Hi, Li Lei. Are you busy with your homework now?
B: Oh, yeah, Da Wei. And you?
A: I'm here for a book. Hey, Li Lei. Have a break! We should be outside in the fresh air. It's good for us.
B: Sorry, I can't. I must hand it in tomorrow.
A: Oh, I see. But we can't always stay indoors. We must often take exercise.
B: Never. I hardly have time now. A sea of homework almost takes up all my free time. It's sad but that's life.
A: You mean my life? In fact, I'm also very busy like you. But you know I like sports. Whenever I have a little time, I will try them.
B: No wonder you are so energetic.
A: Yeah, better health, better grades.
B: Yes, you are right. It sounds as if I should also try to exercise often in the future. Da Wei, shall we play basketball for a while now?
A: OK. Let's go!
The pyramids in Egypt are thought one of the Seven Wonders of the Ancient World.
There are 80 pyramids in Egypt. The three great pyramids at Giza were built 4, 000 years ago. And Khufu's Pyramid is the biggest one, it was built with more than 2. 3 million rocks. It was built on a square base. The base is about 230 metres long. The original height of the Pyramid was 146. 5 metres when it was first built, but over the years, it has lost about 9 metres, so today it is only 137 metres high.
The pharaohs (法老) set out to build pyramids as tombs (陵墓)for themselves. They are the wonders of the world. The pyramids show not only the buildings for us, but also the human's knowledge in ancient times. The pyramids belong to Egypt, but the pyramids also belong to the world.
Many people in modern times want to know how the ancient Egyptians set up them? It's still a puzzle now. Many scientists haven't found out the answer to the problem.
