单选题In the United States, the first day nursery, was opened in 1854. Nurseries were established in various areas during the 1 half of the 19th century; most of 2 were charitable. Both in Europe and in the U.S., the day nursery movement received great 3 during the First World War, when 4 of manpower caused the industrial employment of unprecedented (前所未有) numbers of women. In some European countries nurseries were established 5 in munitions (军火) plants, under direct government sponsorship. 6 the number of nurseries in the U.S. also rose 7 , this rise was accomplished without government aid of any kind. During the years following the First World War, 8 , federal, State, and local governments gradually began to exercise a measure of control 9 the day nurseries, chiefly by 10 them. The 11 of the Second World War was quickly followed by an increase in the number of day nurseries in almost all countries, as women were 12 called up on to replace men in the factories. On this 13 the U.S. government immediately came to the support of the nursery schools, 14 $6,000,000 in July, 1942, for a nursery school program for the children of working mothers. Many States and local communities 15 this Federal aid. By the end of the war, in August, 1945, more than 100, 000 children were being cared 16 in daycare centers receiving Federal 17 . Soon afterward, the Federal government 18 cut down its expenditures for this purpose and later 19 them, causing a sharp drop in the number of nursery schools in operation. However, the expectation that most employed mothers would leave their 20 at the end of the war was only partly fulfilled.

单选题If you intend using humor in your talk to make people smile, you must know how to identify shared experiences and problems. Your humor must be relevant to the audience and should help to show them that you are one of them or that you understand their situation and are in sympathy with their point of view. Depending on whom you are addressing, the problems will be different. If you are talking to a group of managers, you may refer to the disorganized methods of their secretaries; alternatively if you are addressing secretaries, you may want to comment on their disorganized bosses. Here is an example, which I heard at a nurses" convention, of a story which works well because the audience all shared the same view of doctors. A man arrives in heaven and is being shown around by St. Peter. He sees wonderful accommodations, beautiful gardens, sunny weather, and so on. Everyone is very peaceful, polite and friendly until, waiting in a line for lunch, the new arrival is suddenly pushed aside by a man in a white coat, who rushes to the head of the line, grabs his food and stomps over to a table himself. "Who is that?" The new arrival asked St. Peter. "Oh, that"s God," came the reply, "but sometimes he thinks he"s a doctor." If you are part of the group which you are addressing, you will be in a position to know the experiences and problems which are common to all of you and it"ll be appropriate for you to make a passing remark about the inedible canteen food or the chairman"s notorious bad taste in ties. With other audiences you mustn"t attempt to cut in with humor as they will resent an outsider making disparaging remarks about their canteen or their chairman. You will be on safer ground if you stick to scapegoats like the Post Office or the telephone system. If you feel awkward being humorous, you must practice so that it becomes more natural. Include a few casual and apparently oK-the-cuff remarks which you can deliver in a relaxed and unforced manner. Often it"s the delivery which causes the audience to smile, so speak slowly and remember that a raised eyebrow or an unbelieving look may help to show that you are making a light-hearted remark. Look for the humor. It often comes from the unexpected. A twist on a familiar quote "If at first you don"t succeed, give up" or a play on words or on a situation. Search for exaggeration and understatements. Look at your talk and pick out a few words or sentences which you can turn about and inject with humor.

单选题You wouldn't expect an Information Age company like Intel to get on the wrong side of environmentalists, but the company's recent 42 billion expansion at Rio Rancho, New Mexico, plunged the world's largest semiconductor maker into an age-old Western problem: water rights. Chip plants consume millions of gallons of water a day, mainly to wash microscopic dirt from the surface of chips. That's a problem in the dry West, where, as Twain remarked, whiskey is for drinking, water is for fighting about. During construction of the new 1.3 million-square-foot chip-making plant, which starts production this month, residents and activists complained that the company's expanding thirst would be too great a drain on local supplies. After weeks of public hearings, the state of New Mexico last year granted Intel 72% of the water it requested. The strife at Rio Rancho is the most intense the industry has faced. "I think it sensitized us, " says Howard High, spokesman for Intel. "We have a lot of efforts under way to try and minimize the amount of water we use. " Current conservation efforts may not work for an industry that in North America is expected to double in size to $ 75 billion in sales in the next three years. The trend is to reuse treated wastewater from chip cleaning in places such as cooling towers and air-conditioning systems. Motorola employs such methods in Phoenix and Austin. Recycling water for chip cleaning is the most logical approach. But the technology to make ultra-pure water for such a closed-loop system is still too costly. New technologies could eventually take the water out of chip cleaning. One company, Radiance Services, a six-person start-up based in Bethesda, Maryland, holds patents for a new "dry cleaning" method. Using laser light and inert gas (惰性气体) to lift impurities (杂质，不洁物) from surfaces of a chip, Radiance claims its process can clean as effectively as the current water-based methods.

They are made from a variety of materials, such as wax and glass, so skillfully that they can scarcely be distinguished from natural flowers. In making such models, painstaking skill and artistry are called for, as well as thorough knowledge of plant structure. The collection of glass flowers in the Botanical Museum of Harvard University is the most famous in North America and is widely known throughout the scientific world. In all, there are several thousand models in colored glass, the work of two artists-naturalists, Leopold Blaschka and his son Rudolph. The intention was to have the collection represent at least one member of each flower family native to the United States. Although it was never completed, it contains more than seven hundred species representing 164 families of flowering plants, a group of fruits showing the effect of fungus diseases, and thousands of flower parts and magnified details. Every detail of these is accurately reproduced in color and structure. The models ate kept in locked cases, as they are too valuable and fragile for classroom use.

单选题Higher demand from developing countries and oil producers is offsetting the lower demand of wealthy countries. Consumption in these countries will rise 3 percent in 2008, or 1.2 million barrels a day, projects the International Energy Agency. Many of these countries subsidize fuel so that final customers are insulated from price increases. Gasoline is about 25 cents a gallon in Venezuela and about 60 cents in Saudi Arabia, Kuwait and Iran. There"s been a huge transfer of power to oil producers. Even at $100 a barrel, Saudi Arabia, Kuwait and the United Arab Emirates will earn almost $8 trillion in oil revenues between now and 2020, estimates the McKinsey Global Institute. More troubling are the political implications. "This has really strengthened the Iranians, Russians and Venezuelans to be more provocative in the world," says Larry Goldstein of the Energy Policy Research Foundation. Although governments control crude supplies, private companies have dominated distribution. Anyone can buy oil at a price. Now oil could become a political commodity, used by governments to cement their alliances, offered to friends at a discount; withheld from rivals. How can we retrieve some of our lost power? The first thing is to get out of denial. Stop blaming oil companies, "speculators" and other scapegoats for a situation not of their making. Next, we need to expand oil and natural-gas drilling in the United States, including Alaska. No, we can"t "drill our way" out of this problem. But we can augment oil supplies and lessen price strains on global markets. It might take 10 years or more, because new projects are huge undertakings. But delay will only aggravate our future problems, just as past errors aggravate present problems. Finally, we need to let high prices work. Aside from encouraging fuel-efficient vehicles and disciplining driving habits, they may also stimulate development of new biofuels from wood chips, food waste and switch grass. Production costs of these fuels may be in the range of $1 a gallon. If true, that"s well below today"s wholesale gasoline prices. To assure new producers that they wouldn"t be wiped out if oil prices plunged, we should set a floor price for oil of $50 to $80 a barrel, about 40 percent to 60 percent of today"s levels. It"s a worthy idea and can be done with a standby tariff. It would activate only if prices hit the threshold. We know that oil prices are unpredictable, and should a price collapse occur, Americans wouldn"t be deluded into thinking we"ve returned permanently to cheap energy. We"ve made that mistake before.
