V. 阅读理解  

Thousands of years ago, Shennong, who had an ox (牛) head and human body, lived in the south of ancient China. Seeing that local people were suffering from disease, he built ladders (梯子) and houses on a high mountain to store medical plants. To remember him, people named the place Shennongjia.

The story makes Shennongjia in Hubei an inviting place for tourists. Traveling there is a quite different experience, as you can see sceneries (风景) of the four seasons from different height. “When the bottom of the mountain is summer, the top is spring and while the foothill is autumn, the top is covered with ice,” local people say of the special climate of Shennongjia.

Shennongjia is also home to 5,000 kinds of animals and plants. Many rare animals live there, such as the golden monkey and the Asian black bear.

One interesting thing about Shennongjia is its story of wild men. Some people said that they saw big foot marks. Yet so far, scientists haven’t proved (证实) it is true and some say they are just bears.

The beautiful place has recently received a new title. It was added to United Nations World Heritage (遗产) list as a natural site. China now has 50 world heritage sites, only less than Italy in the world.

A. had an ox body   B. grew medical plants for people     C. helped people with illness

22. In Shennongjia, __________.

A. there are 50,000 kinds of animals and plants

B. people can experience four seasons up the mountain

C. people can climb ladders and get to the houses on a high mountain

23. “Rare animals” are animals which are __________.

A. big and dangerous   B. smart and expensive      C. not often seen

A. the story of Shennong

B. the truth of wild men in Shennongjia
