高中英语必修2 教师用书 Unit 1

The world we live in is full of things that can't be explained even by today's science. They are mysterious because no satisfactory① answers have been offered② to explain them. Though these mysteries have puzzled people for a long time, they still show great interest in them.

The most famous one is the UFOs. UFO stands for③ Unidentified Flying Object. According to some witnesses, they are bright and move at a slow, steady speed with little noise. Yetis are famous too. The Yeti has been called the “missing link” — half-man, half-beast. It is supposed to④ live in the highest mountain in the world — Mount Qomolangma. Do you hear of the story of Crop Circles? Crop circles often appear in spring or summer when wheat, barley, rye⑤ or maize⑥ is growing in the fields. A crop circle is a large pattern created by the flattening⑦ crop. The first crop circle was discovered in England in 1647. They have been found in many places all over the world. Stonehenge is a monument of huge rock slabs⑧ in the southwest of England built in the Stone Age. It is believed that Stonehenge served some sort of religious purpose. Up to now nobody knows for sure⑨ how it came into being⑩.

There are many other unexplained things in the world, such as the pyramids in Egypt and the Great Wall in China. We believe that as the science and technology develops, the people in the world will find the answers to explain the mysteries.
