Thousands of years ago, the kings of Egypt built strong tombs for (they). Over these tombs they built pyramids. They thought their bodies would be well kept in these tombs they could come back to life.

There are about 80 pyramids in Egypt. But the Great Pyramid is (big) of all. It is nearly 5,000 years old. It (make) of 2,300,000 huge stones. Some weigh as much as fifteen tons. It (take) more than 100,000 men twenty years to build it.

When you look at the pyramids, you can't help wondering how the Egyptians (be) able to build them thousands of years ago. Scientists have studied the pyramids, but nobody can tell just the Egyptians built them so long ago.

Inside the pyramids are the rooms for the bodies of the kings and queens with wonderful treasures. Thieves  (break) into some of the pyramids and taken away many of the treasures to foreign countries. They have even stolen the mummies. When the kings had the pyramids built them, they perhaps never, (think) this would happen.

The next time you look up at the sky and see a cloud that looks like Mickey Mouse or your favorite fruit，look again. It may not be a cloud，but a Flogo-a logo that flies. It's a new form of advertising in the sky that's never been used before. It's a different way to market your products，logos，and events.

These funny logos are made with soap bubbles mixed with a little helium（氦气），which makes them lighter than air and float in the sky. Special machines are used to make these new funny Flogos. The machine, which can be rented for $2,500 a day, can make a Flogo every 15-25 seconds.

Flogos can fly much higher or lower if needed. They can last from a few minutes to an hour anywhere in the sky, depending on the weather conditions. Though they can fly up to 20,000 feet, they usually float around at 300-500 feet. Flogos are only white now, but people hope to have more colorful Flogos in the near future.

Flogos are green, 100% environmentally safe, because the soap used to make the Flogo comes from plants and leaves. So this fun way of advertising is healthy and good for the environment.
