They plan to be the first to arrive at the yard-sales. What are these yard-sale shoppers looking for? Secondhand things, of course. Yard-sale shoppers aren’t the only people who like used goods. From Australia to the USA, westerners love to buy other people’s things. E2 the rich people look for an antique (古玩) among used goods. Some people buy used goods to save money, others do that to c3 antiques.

How old is old?

For those in Asia. 5, 000-year-old antiques sit in museums. Western antiques are not so old. But American goods even more than twenty years old have value. An ice-cream maker from the 1920s could be $50.S4 from World War I could sell for $4,000 or more.

Some people own old things because they want to make money from them. They go to classes and read books to learn which goods will have more value or are liked by collectors. Others simply buy old things they think interesting. Those who do not want to make money from the old goods say, “Don't buy it u5 it's useful.”

Where to find them?

Secondhand goods can be found in a variety of places. Saturday morning yard sales are the r6 places for those who start to take up the hobby. The flea(跳蚤)market is another place. You won't find fleas, but you may find a wide variety of old things.

Shopping at a flea market for the first time is not easy. You have to look t7 things patiently and carefully to find something you really want.

【题目】 A group of scientists from Sweden have unlocked one of nature's biggest secrets. The scientists have worked out how spiders make such strong silk when they build their webs. The silk that spiders make is strong and even tougher than steel. Being able to produce man-made spider silk has long been a dream of many scientists. Now, researchers from the Swedish University of Agricultural Sciences have, step by step, developed a method that works. They've found that the materials for webs arc in a spider's silk gland (丝腺) as protein. The gland has a level of acidity (酸度) that helps make the protein into very strong silk. The researchers reported that they could produce man-made spider silk by copying the process.

The new man-made silk could be very useful to humans. Doctors are interested in it. They think it can help people get well after a bum. Some doctors believe the new silk could be used to take the place of the torn ligaments (撕裂的韧带) in the body. Plane makers and makers of protective clothing also see many uses for the new silk.

Senior researcher Anna Rising spoke about how the new discovery could be. She said, "This is the first successful example of copying spider silk-making process. In the future, this may allow industrial production of man-made silk, which can be used in many fields and make our life much better. The silk could become a valuable material for us."
