• The longest bull run in a century of art-market history ended on a dramatic note with a sale of 56 works by Damien Hirst, Beautiful Inside My Head Forever, at Sotheby's in London on September 15th, 2008．All but two pieces sold, fetching more than ￡ 70m, a record for a sale by a single artist. It was a last victory. As the auctioneer called out bids, in New York one of the oldest banks on Wall Street, Lehman Brother, filed for bankruptcy.

  The world art market had already been losing momentum for a while after rising bewilderingly since 2003．At its peak in 2007 it was worth some $ 65 billion, reckons Clare McAndrew, founder of art Economics, a research firm-double the figure five year earlier. Since then it may have come down to $ 50 billion. But the market generates interest far beyond its size because it brings together great wealth, enormous egos, greed, passion and controversy in a way matched by few other industries. In the weeks and months that followed Mr Hirst's sale, spending of any sort became deeply unfashionable. In the art world that meant collectors stayed away from galleries and salerooms. Sales of contemporary art fell by two-thirds, and in the most overheated sector, they were down by nearly 90% in the year to November 2008．Within weeks the world's two biggest auction houses, Sotheby's and Christie's, had to pay out nearly $ 200m in guarantees to clients who had placed works for sale with them. The current downturn in the art market is the worst since the Japanese stopped buying Impressionist at the end of 1989．This time experts reckon that prices are about 40% down on their peak on average, though some have been far more fluctuant. But Edward Dolman, Christie's chief executive, says: "I'm pretty confident we're at the bottom. " What makes this slump different from the last, he says, is that there are still buyers in the market. Almost everyone who was interviewed for this special report said that the biggest problem at the moment is not a lack of demand but a lack of good work to sell. The three Ds--death, debt and divorce-still deliver works of art to the market. But anyone who does not have to sell is keeping away, waiting for confidence to return. In the first paragraph, Damien Hirst's sale was referred to as "a last victory" because______. A．the art marker had witnessed a succession of victories B．the auctioneer finally got the two pieces at the highest bids C．Beautiful inside My Head Forever won over all masterpieces D．it was successfully made just before the world financial crisis

• Building a house costs quite a lot of money. Suppose you plan to build a house. Your first step is to find a right piece of land. Your choice(选择) will depend on many different things. You will probably try to find a sunny place with pleasant surroundings(环境) near shops and bus stops not too far from your friends and the place where you work.

  Next you will find a good builder and together with the builder you will work out a plan. The builder will draw the plan. It will show the number of rooms their position and size and other parts such as windows doors and electric outlets(电插座). The builder will work out how much money is needed to build your house. He will work out the cost of the wood bricks the glass and everything else that must be used in building the house. Later on when he starts to build this estimate(预算) must be corrected and revised(修订). His estimate is based on existing prices but prices of such things may change and many other things may happen between the time when he makes the estimate and the time when he builds the house. When the builder gives his estimate you may wish to change your plan. (You may also wish to change your builder if his estimate is too high!) You may find that the house you wanted at first costs too much or that you can spend a little more and add something to your plan. The builder&39;s estimate depends on the plan but the final plan depends on the builder&39;s estimate. 1.The best title of this passage is_______. A.Building a House Costs Much Money B.Estimate Is Important C.Planning a House D.Depend on the Builder 2.The first thing for a person to build a house is_______. A.to get as much money as possible B.to find a suitable piece of land C.to work out a plan D.to make an estimate 3.The underlined phrase "draw the plan" in this passage means_______. A.drawing a picture of a building or a room B.making a plan C.working out a solution D.taking a picture out of a room 4.What is the relationship(关系) between the estimate and the plan？ A.The plan depends on the estimate. B.The estimate depends on the plan. C.The plan has nothing to do with the estimate. D.The estimate and the plan depend on each other.
