From the very beginning, water has furnished man with a source of food and a highway to travel. The first civilizations arose (76) water was the dominant element in the environment, a challenge (77) man’s ingenuity. The Egyptians invented the 365-day calendar (78) the Nile’s annual flooding. The Babylonians (79) were among the most famous law-makers in ancient times, invented laws (80) water usage. Water inspired the Chinese to build a 1,000 miles’ canal, a complex system (81) , after 2,500 years, remains particularly in use and still commands the astonishment of engineers. But the ancients never found complete solutions (82) their water problem. The Yellow River is also known as "China’s Sorrow". It is so unpredictable and dangerous (83) in a single flood it has caused a million deaths. Floods slowed the great (84) of the Indus River Valleys, and innumerable damages ruined much of its land. Today, water dominates man as it always has done. Its presence continues to influence the location of his homes and cities; its violent variability can (85) man or his herds or his crops; its routes link him to his fellows; its immense value may add to the already dangerous political conflicts. There are many examples of this in our own time.

Electronic Teaching The potential of closed-circuit television and other new electronic teaching tools is so great that it is fascinating to visualize "the school of tomorrow" Televised lessons will originate from a central building having perhaps four or five master studios. The lessons will be carried into classrooms all over a city, or even an entire country. After a televised lesson has been given, the classroom teacher will take over for the all-important "follow-up" period. The students will ask any troublesome questions, and difficult points will be cleared up through discussion. The teacher in the classroom will have additional electronic tools. On the teacher’s desk, the traditional chalk and erasers will have been replaced by a multiple-control panel and magnetic tape player. The tape machines will run pre-recorded lessons which pupils will follow by headphones. The lessons will be specifically geared to the students’ levels of ability. For instance, while the class as a whole studies history, each student will receive an individual history lesson, directed to his particular level of ability. Should question arise, the students will be able to talk directly to the teacher on individual "intercoms" without disturbing the rest of the class. In this way, the teacher will be able to conduct as many as three classes at the same time. With the rapid development of computer science, students will be aided with specially prepared multimedia software to study their subjects better. Homework will possibly be assigned and handed in via electronic mail system. Students can even take examinations on their computer linked with the teacher’s and get the score instantly. They will get certificates or diplomas if they pass all the required examinations. Experts believe that this type of education will be very popular in the years ahead. After a televised lesson, which will not happen
