Toilet waters, colognes （科隆水）and perfumes all have pleasing aromas （香味）. When purchasing them at a store, however, you will find that each of the three has a different price range. Their aromas are created by perfume oils. These can be very costly. Toilet water, which is the least expensive, contains about two percent perfume oil. Cologne, which is slightly more expensive, has three to five percent perfume oil. Perfume, containing from ten to twenty percent perfume oil, is the most expensive.Perfume oils, also called "essential oils", provide the special odors of perfumes. These oils come from the flowers, leaves, stems, roots, and seeds of plants. One of the most desirable essential oils comes from the jasmine. Attar is one of the most expensive oils. It is obtained from a unique rose. This special flower grows only in Bulgaria and Turkey.Another ingredient of perfume is called a fixative——a substance that makes the aroma of the essential oils long-lasting. The best fixatives are quite expensive. This is because they can be obtained only from certain animals. Musk comes from the scent gland of the musk deer that lives in Asia. Castor comes from beavers, and civet is taken from civet cats. Ambergris, the rarest of fixatives, is a substance sometimes found in sperm whales.The last two ingredients in perfumes, however, are not costly. Almost all perfumes contain synthetic substances that are obtained from coal tar or chemicals. All perfumes also contain alcohol, in which the other ingredients are dissolved. The greater the amount of synthetic materials and alcohol, the cheaper the perfume is to make.Some perfumes, therefore can be very expensive, while others can cost less. The more expensive ones are used for cosmetics: lipsticks, powders, lotions, and of course, the fragrant liquid dabbed or sprayed on the body. The less expensive ones are used in industry. They are key ingredients in the making of paper, plastics, paint, and rubber products, which otherwise would have unpleasant odors.1.Toilet waters, colognes and perfumes are different in prices because （ ）.2.The major ingredients of perfumes are （ ）.3.The best fixatives are very expensive because （ ）.4.The function of alcohol in perfumes is to （ ）.5.People use perfumes in paper-making in order to（ ）.

Three years ago, French entrepreneur Gary Cige was helping a friend hang a mirror in his country house when they realized they needed a drill. But where to get one? Buying one would cost 150 Euros, a huge waste considering they needed it for only half an hour. And since it was Sunday, every rental shop would be closed. Yet as Cige realized, they were likely surrounded by drills. Odds are, at least one of his friend’s neighbors had a drill that was sitting idle. Why wasn’t there some easy way to find a drill to rent — for just a few bucks?Propelled by that idea, Cige cofounded Zilok, a startup that offers precisely this service: People post possessions they’re willing to rent out, along with a price. Cige’s Web site processes the fee, tracks the reputation of your renting partner, and— in France — even issues insurance for your item. After two years in business, Zilok has 150,000 items listed, with 6, 000 transactions a month, and it’s the fastest-growing renter of cars in France.Peer to peer renting — and similar services— has boomed in the past few years. Some work like Zilok, while others let people exchange things they own (such as book and CDs at Swaptree). A few even let you take advantage of space that’s lying fallow, like Shared Earth, where land owners hook up with gardeners.In essence, we’re seeing a new relationship to property — where access trumps ownership. We’re using bits to help us share atoms. The genius of these sites is that they make a virtue of modern society’s ecological sin: oversupply. In developed countries, we’re prosperous but horribly wasteful. We buy tons of things we use rarely —and which sit unused in basements and storage lockers.Peer renting and sharing is, of course, an old idea. But it never took off before, for logistical reasons; it was too hard to connect millions of renters to owners. The Internet’s Bayesian ability to make markets solved that problem. The net also provides crucial glue, as the new startup Zimride proves. Ride-sharing systems have historically petered out because it can be kind of creepy to pick up strangers. So instead, Zimride lets people share rides with friends of friends from Facebook through either Facebook Connect or networks it sets up for individual organizations. “The limiting factor before was trust,” Zimride cofounder Logan Green says, “and Facebook solved that.”Besides the environmental benefits, there are economic ones. Some users of Zilok make more than $1,000 a month circulating their possessions. Granted, it’s not enough to quit your day job, but a little extra dough for almost no effort never hurts.As peer-to-peer renting and swapping evolves, tools like geolocation and micropayments could make it even smoother and more ubiquitous. Rachel Botsman, coauthor of What’s Mine Is Yours — a new book that documents “collaborative consumption”— envisions a world in which everyone’s stuff reports its status in real time: Where is the right now? Is it available for use by someone else?Your property could circulate for days or months, making your money instead of molding in your garage “We’re facing a revolution in the way we think of ownership,” Botsman says. Or, to put it other way, your drill may be my drill, too.
