The Forbidden City, or the Palace Museum, has been considered a great old museum for a long time.     16     Nowadays, such cultural and creative products have been one of the hottest topics and they are popular among Chinese people.

Since 2007, the Palace Museum has come up with more than 9,600 products. The products include notebooks with embroidery (刺绣) covers and dolls of emperors and empresses.     17     It was reported that the products were sold for about 1 billion yuan in 2016.

Besides the products, the Palace Museum also created an app called A Day of an Emperor.     18     Users will be guided to learn about a day of life and work of an emperor of the Qing Dynasty.

Several years ago, a documentary called Masters in Forbidden City became popular online.     19     They say that they can learn a lot about Chinese history and culture by watching the documentary. The documentary also makes them want to work at the museum.

The Great Pyramid of Giza is one of the wonders of the ancient world. It was     21     more than 4,000 years ago in Egypt. It is so     22     that millions of tourists from around the world come to visit it every year.

In Egypt there are about 100 pyramids and the     23     one is the Great Pyramid of Giza. It     24     on the west bank of the Nile. In fact, all the pyramids along the Nile are on the west bank. The ancient Egyptians compared the rising of the sun to the beginning of life and the setting of the sun to the end of life. That is     25     their dead bodies were buried (埋葬) on the west bank of the Nile.

You can     26     imagine how huge the Great Pyramid of Giza is. It has over 2 million stones. Some are as heavy as five school buses.     27     they were heavy, workers were able to put a block into the pyramid every three minutes.

The workers—Egyptian men and women worked in teams. The teams had different     28    . Some dug up the stones. Some moved them. Some cut the stones. The last team put the stones into the pyramid. There were so many different teams, but the pyramid is perfect. No stone is in the     29     position.

But how did the Egyptians move those heavy stones to the top     30     any modern machinery (机械)? No one knows for sure. Many things about the Great Pyramid of Giza are still a mystery.

We are staying in Hunan Province. I’m having a wonderful time here in Zhangjiajie, a city     31     is famous for the strange shapes of its mountains and rocks. Some of the rocks look like humans while others look like wild animals. Last night, we     32     woken up by some noise. We came out silently and found it was from a hungry monkey.

This morning,     33     I was walking along the river, I pulled some leaves off a tree. Lingling said it was wrong. I apologized and promised not     34     do that again. Tomorrow we’re going to Dongting Lake,     35     second largest freshwater lake in China. I can’t wait to fly there!
