单选题. It is hard to imagine life without Arabic numerals (数字). No other number system ever invented has a simple way to write a number like 1984. In Roman numerals, it comes out like this: MCMLXXXIV. Imagine how difficult it would be for a school pupil to remember it! The Arabs, however, call their numbers "Indian numerals". This is probably because they got the original idea a long time ago from India. There were no printed newspapers or scientific magazines then, so mathematics traveled along the same routes that silk did, as businessmen sold and bought goods. The Arabs took the new numbers and made improvements that quickly led to advances in technology. The achievement of Arabic technology can be seen from a passage in a 10th-century book about an Arabic city: "The neighboring country, showed the results of careful work in agriculture, trade, and industry. Rice and many other plants were grown in fields with water supplied by Arab engineers. The city included 900 public baths, stone-covered streets, fountains, and beautiful buildings." At this time, London was a small town with dirty streets, and Berlin was a farming village. In fact, cities outside the Arab world did not reach the same level of social development until centuries later.1. This passage tells us that the Arabs were a people ______.

单选题. People and the sources of air pollution are found in the same places. This means that cities with large populations have the biggest problem of dirty air. Air pollution is caused by many different things. A major source of air pollution is the gas fumes (烟) from cars. Another major source of dirty air is the burning of coal and oil for energy. This energy is needed to make electricity. Of course, much more electricity is used in the city than in the country. On the average, we throw away more trash and garbage than the year before. The burning of garbage leads to air pollution. Many major industries are also the cause of the dirty air in and around the cities. The fumes from iron, steel, chemical, and petroleum production add particles(粉尘) to the air. The effects of air pollution range from mild headaches to death. The levels of pollution found in heavy traffic may cause headaches for loss of clear sight. Wherever coal and oil are used for fuel, fumes may kill trees and plants. In some of the larger cities, these fumes endanger the lives of human beings by leading to lung diseases and causing early death.1. From the passage, we know that ______.
