The expression "a thirst for knowledge" may soon have a new meaning for millions of people who have no way to get clean water. Researchers have developed a book with specially treated pages that can turn dirty water into clean and drinkable water. They say their invention could improve the lives of many in the developing world. About 700 million people around the world are at risk of disease or even death because their drinking water is not clean. The water is polluted by harmful bacteria. The book contains 25 pages. Each page is about one millimeter thick. The pages contain very small particles   of silver. The pages can be used as filters to remove harmful microorganisms   that can pollute drinking water. The filter kills the organisms that pass through it. Pictures on the pages show the dangers of dirty water and how to use the book for those unable to read. The pages are made of filter paper. They are designed to be torn from the book. Water can be poured through the paper to be cleaned. Ms. Dankovich, the inventor, says each page can treat up to 100 liters of water. She recently presented her invention at the meeting of the American Chemical Society in Boston, Massachusetts. She was asked whether she had considered adding classic literature on the book's pages. "The idea of classic texts--that's of interest maybe later. We have discussed a little bit more exciting text. But we really haven't had the time to go through _ " she says. Teri Dankovich and another researcher tested the drinkable book in Bangladesh, Ghana and South Africa. The tests proved to be successful. Water for Life, a non-governmental organization, has provided financial support for the project. What do we learn about the book from the text? A) It sells well around the world. B) It has pages with several functions. C) It is about environment protection. D) It can treat about 100 liters of water.

(Question)
Bean and other seed shoots are also known as sprouts  . The dry bean seeds contain a store of nutrients just waiting to be released when they sprout. Under the right conditions they will germinate  .  As they grow, the food value of the seeds is multiplied into vitamins, minerals   and other nutrients. This happens almost overnight! It is easy to grow your own sprouts, but you need to buy your seeds from supermarkets or health food stores. Seeds for planting in the garden are often powdered with chemicals, so when becoming sprouts they are not safe to eat. Try growing sprouts from a variety of beans and seeds. You will find different sprouts at different stages. Bean sprouts are best when they are about three centimeters long. Wheat and sunflower sprouts taste best when the sprouts and the seeds are of the same length. If the sunflower sprout is too long it leaves a funny stinging feeling in the throat after eating. Alfalfa sprouts are best when their small leaves are well developed. Pea and soybean sprouts are good long or short. If you leave your sprouts in filtered sunlight for a few hours, the leaves will turn green as chlorophyll   is added. Eating sprouts with green leaves benefits your blood, cells, and the digestive system. Which of the following is NOT true according to the passage? A) Sprouts of seeds for planting in the garden may not be safe to eat. B) Alfalfa sprouts taste best when their small leaves are more fully grown. C) All sprouts taste best during the early stage of their growth. D) Sunlight will make the leaves of sprouts green.

Ques: We have recently heard a great deal about the effects of computers on our social and economic organizations. In industry, computers mean automation , and automation means unemployment. Computers in the prefix = st1 /United Stateshave already begun to take the place of workers whose tasks are simple. The variety of jobs, done only by humans in the past, which the machine can perform more rapidly, accurately and economically, increases with each new generation of computers. If we follow this trend, we will be faced with mass unemployment for all but a handful of highly trained professionals who will be more powerful and overworked than they are now. What can we do about it? It is foolish to dream of making history backwards. We cannot pass laws forbidding the advancement of science and technology. The computing machines are here, and they will grow because engineers want to build them, and politicians want their help in the process of government. In short they will develop and become popular because they enable us to complete tasks that could never before have been done, no matter how many unskilled laborers we might have set to work. Computers will continue to increase our intelligence for just the same reason that engines continue to strengthen our muscles. The question we must ask is not whether we shall have computers or not have computers, but rather, since we are going to have them, how we make the most humane and intelligent use of them. In the article, the author believed that computers will continue  _  . A) to have had effects on social economy B) to cause mass employment C) to develop in the future D) to have good effects on social organizations

On the first day of school I brought my camera to school. I gave the students a piece of 8 x11 cardboard , and asked them to write their names on both sides. As they finished, I asked them to get into groups of three to four students and took photographs of them holding their name cards. After school, I developed the film and printed two sets of photos. That evening, I started to match the names with the faces. I kept one set of pictures at home for about a week so that I could review their names each night. On the second day of school, I put up the other set of photos as a bulletin board  , with a title such as "Presenting Room 108, ..." The kids loved it! After I had learned all of their names I brought the second set back to school and stuck them onto an 8 x11 sheet of paper. I placed it in the classroom for other teachers. The cardboard name cards that were made on the first day were collected and put on a shelf. From time to time, they were given back to the students and placed on their desks so that guests or supply teachers   could identify all of the students. I've been doing this with my grade 7 students for the last nine years and they liked it. It's fun to bring the photos out again at the end of the school year to see how much they have all changed in ten months. Why did the writer leave the second set of the photos at home? A) To memorize the students' names at home. B) To make cardboard name cards for supply teachers. C) To make a bulletin board in the classroom. D) To match the students' names with their faces
