　　What is the main idea of the passage?

　　A Astronomers now feel certain that no life exists on the surface of any other planet in our solar system.

　　B It is realistic to send a spacecraft far beyond our solar system to search for E.T. life.

　　C There is no E.T. life on Mars.

　　D Using radio telescopes to listen out for message from E.T. life, scientists have discovered that the new equipment nay help in the development of new communication and medical technologies.

　　22 It is burning hot in Mali, an island country in Africa, where the highest temperature even reach 55℃, while the average temperature of the whole year there maintains above 45℃. But to our great surprise, the tourism there is getting very well. Nearly all the year round the tourists can be seen coming and going.

　　That is because there are a large number of In-the-Well Hotels in Mali. It means that first of all, people have dug a thirty-metre-deep well under very hot land surface, then in the wall of the well several empty caves, about two metres high each, are made. In these caves beds are arranged.

　　Obviously, In-the-Well Hotel, not as hot as it is out of the well, remains only about 12~20℃. In the cave rooms, tourists can find all the daily necessaries.

　　It not only frees the guests of the country from the hot weather but also gives them a new and fresh experience. So it is appealing to the tourists coming all parts of the world.
