The men of Symi dug out the earth to make the ponds. Over each pond is a low cover. It is made of glass that you can see through. At night, sea water is taken into the ponds. The next day, the hot sun shines through the covers. The sun light turns the water into vapor and the vapor goes up from the ponds. The salt is left behind. As it goes, the vapor became mist. On the inside of each cover, the little drops of mist run together to make big drops. These drops run down the sides of the cover, filling other ponds with fresh water. The salt left in the ponds is washed out each night. Then more sea water is taken in. The factory is ready for the next day's work. The covers and other parts of the factory cost very little. Sea water and sun cost nothing. Most people of Symi are poor. So to them this new way of getting fresh water seems wonderful. Question: The men of Symi dug some long ponds _ . Answer:

Read the following article and answer the question. Article: Online shopping is growing fast in China, and more and more Chinese are buying books online. At the same time, traditional bookstores are facing new challenges. A bookstore in Beijing is going out of business . All of its books are on sale. Bookstore owner Wang Jian says hot sales of books on the Internet pushed him to change the way he did business. China has the highest online book buying rate in the world. More than years ago, dangdang.com became the first online bookseller, and now becomes very important in the Chinese online book market. Facing this challenge, the Xinhua Bookstore also built its online store a few years ago. Zhang Jian, CEO of the Xinhuabookstore.com, says now they are enlarging their online services. A "price war "is taking shape between traditional bookstores and online bookstores. Faced with the low-cost advantage of online bookstores, traditional ones can do nothing but lower their prices. At the same time, online bookstores are also starting price wars between each other. Now some traditional bookstores are trying their best to attract buyers in their own way. They exhibit books better and provide a very relaxed reading environment in the bookstore. Even though, traditional bookstores can hardly compete with some of the advantages of online bookstores, for example 24-hour service. Question: What made Wang Jian change the way he did business? Answer:
****
A:
The small sales of his books.
