Water problem in the future will become more intense and more complex. Our increasing population will tremendously increase urban wasters, primarily sewage. On the other hand, increasing demands for water will decrease substantially the amount of water available for processing wasters. Rapidly expanding industries which involve more and more complex chemical processes will produce larger volume of liquid wasters, and many of these will contain chemicals which are noxious. To feed our rapidly expanding population, agriculture will have to be intensified. This will involve ever-increasing quantities of agricultural chemicals. From this, it is apparent that serious steps must be taken immediately to develop corrective measures for the pollution problem. There are two ways by which this pollution problem can be settled. The first relates to the treatment of wastes to decrease their pollution danger. This involves the processing of solid wasters prior to disposal and the treatment of liquid wasters to permit the reuse of the water or minimize pollution upon final disposal. A second approach is to develop an economic use for all or a part of the wastes. Farm manure(肥料)is spread in fields as a nutrient or organic supplement. Wastes from sewage disposal plants are used in some areas both for irrigation and for the nutrients contained. Wastes from other processing plants may also be used as a supplemental source of water. Many industries, such as meat and poultry processing plants, are currently converting former waste products into marketable byproducts. Other industries are exploring potential economic uses for their waste products.

Toronto's third City Hall, now known as Old City Hall, was designed by Edward James Lennox and declared open on Sept. 18, 1899. Created to provide more space for city officials, it turned out to be the largest building in the city and the largest city building in North America at the time. Lennox took three years to design the City Hall and it took 11 years to build it. Contemporaries believe that the odd carvings(雕刻) above the Queen Street entrance were actually caricatures(漫画) of councilors at the time. Lennox even included himself in the caricatures, on the west side of the central arch (拱门), and left a strange signature in the stonework of the link portions of the building. The third City Hall was originally used as councilors' offices and legal offices, but it is used only as a courthouse today. When the fourth City Hall (the one we know today) was declared open in 1965, Old City Hall was threatened to be pulled down. It was saved by a group of people called the "Friends of Old City Hall." The clock tower stands parallel with the middle of Bay Street, rather than with the center of the building. The bells in the tower were not installed until the building opened. Old City Hall was declared a historical site in 1989. (80)The entire structure cost more than $2. 5 million to build at the time. This is equal to $ 53 million today.

"Equal pay for equal work" is a phrase used by the American women who feel that they are unfairly treated by society. They say it is not right for women to be paid less than men for the same work. Some people say men have more duties than women. A married man is thought to earn money to support his family and to make the important decision, so it is right for them to be paid more. Some are even against married women working at all. When wives go out to work, they say, the home and children are given no attention to. If women are encouraged by equal pay to take full-time jobs, they will be unable to do the things they are best at doing: making a nice home and bringing up children. Women who disagree say they want to escape from the limited place which society wishes them to fill and to have freedom to choose between work and home life, or a mixture of the two. Women have the right not only to equal pay but also to equal chances.

Jarden Zinc (锌) Products, a large zinc plant a few miles outside Greeneville, Tennessee, has a special claim. Since 1982, it has been the only supplier of penny blanks for the U. S. Mint (铸币厂). It's a good business for Jarden—since 2000, the company has earned more than $ 800 million. But it may not be a good deal for the U. S. The value of the penny has been dropping for years. In 2006, it began to cost more than a penny to make a penny. It now costs 2 ￠ to produce a 1 ￠coin. Many countries have stopped using pennies. Is it time for the U. S. to do the same? Jarden and the zinc industry are fighting to keep the penny. Since 2006, Jarden has given $1.2 million to Americans for Common Cents (ACC). The group' s mission is to keep the penny in use. Mark Weller is ACC' s executive director. He argues that there are three main reasons for keeping the penny: Without it, we would become more reliant on the five-cent coin, which also has problems: charities(慈善机构)that depend on penny drives would not be able to raise as much money: and a 2012 survey shows that 67% of Americans want to keep the penny. Many people surveyed said they feared they would end up paying more for products. Many experts disagree with ACC. They point to the dozens of countries that have gotten rid of their lowest-value coins without raising prices for consumers. And charities don' t seem too concerned either. President Barack Obama says the mint could explore using cheaper metals to make pennies. Steel is less expensive than zinc. Pennies are 97.5% zinc and 2.5% copper. But no matter what it is made of, the penny's days may be numbered. Most in-store purchases are now made with credit cards, not cash. Is it time for a change?

During his life, J. S. Bach was not as popular as Beethoven and Mozart during their lifetimes. His music was considered hard to understand and even harder to play. Although Bach wrote more than 1,000 pieces of music, very few were published while he was alive. An employer originally rejected one of Bach' s most famous works, the Brandenburg Concertos. Bach composed the piece in 1721 as part of a job application. He never even got a response, let alone the job he wanted. More than 100 years later, the piece was finally published. Today, you can hear orchestras all over the world playing Bach' s Brandenburg Concertos, which offers just one example of how public opinion of Bach has changed. Now the composer is considered one of the most brilliant minds of Western Civilization. Bach' s music is very complex. During his lifetime no one could imitate him. Instead of writing just one melody(旋律)into his music, he often used two. The two melody lines are kept separate throughout the music, like two voices having a conversation. But they are also precise, like a mathematical equation set to sound. To the skilled listener, Bach's complexity adds endless depth. Bach studied hard and expected his students to do the same. He once said, " I was obliged to be hard-working: whoever is equally hard-working will succeed equally well." Bach was a very patient and kind teacher. Bach combined the notes from different instruments in a new way. More than anything, he wanted to invent. He was always experimenting with new patterns of music. He did not worry that others did not like his music. He just said, "If you cannot please all by your art or your work, satisfy the few. To please many is bad." Bach had a great influence on many of the composers who came after him.
