A.　Goods for auction (拍卖) sales
　　B.　Definition of bidding
　　C.　Way to sell more goods by auction
　　D.　Auction sales in history
　　E.　Brief introduction to auctions
　　F.　Making a larger profit as an auctioneer
【小题1】______
Auctions are public sales of goods, conducted by an officially approved auctioneer. He asks the crowd assembled in the auction-room to make offers, or “bids”, for the various items on sale. He encourages buyers to bid higher figures, and finally names the highest bidder as the buyer of the goods. This is called “knocking down” the goods, for the bidding ends when the auctioneer strikes a small hammer on a table at which he stands.
【小题2】 ______
The ancient Roman probably invented sales by auction, and the English word comes from the Latin auction, meaning “increasing”. The Romans usually sold in this way the goods taken in war. In England in the eighteenth centuries, goods were often sold “by the candle”: a short candle was lit by the auctioneer, and bids could be made while it stayed alight.
【小题3】 ______
Practically all goods whose qualities vary are sold by auction. Among these are coffee, skins, wool, tea, furs, silk and wines. Auction sales are also usual for land and property, furniture, pictures, rare books, old china and similar works of art.
【小题4】 ______
An auction is usually advertised beforehand with full particulars of the articles to be sold and where and when they can be viewed by potential buyers. If the advertisement cannot give full details, catalogues are printed, and each group of goods to be sold together, called a “lot”, is usually given a number. The auctioneer need not begin with Lot 1 and continue in the order of numbers: he may wait until he notices the fact that certain buyers are in the room and then produce the lots they are likely to be interested in.
【小题5】 ______
The auctioneer’s services are paid for in the form of a percentage of the price the goods are sold for. The auctioneer therefore has a direct interest in pushing up the bidding as high as possible. He will not waste time by starting the bidding too low. He will also play on the opponents among his buyers and succeed in getting a high price by encouraging two business competitors to bid against each other.

“They believe self-criticism is what keeps then in line（符合常规的）.

E.Here are some tips you can follow to change your self-critical habits.
F.If you care about yourself, treat yourself really strictly.
G.Then write down how this weakness makes you feel inside.

某校组织学生到涪江河某段测量两岸的距离，采用了两种方案收集数据．
方案一：如图，从C点找准对岸一参照点D，使CD垂直于河岸线l，沿河岸行走至E点，测出CE的长度后，再用电子测角器测出CE与ED的夹角α；
方案二：如图，先从河岸上选一点A，测出A到河面的距离h．再用电子测角器测出A点到对岸河面的俯角β．

（1）学生们选用不同的位置测量后得出以下数据，请通过计算填写下表：（精确到0.1米）
方案一：

测量次数	1	2	3
EC（单位：米）	100	150	200
α	76°33′	71°35′	65°25′
计算得出河宽 （单位：米）

方案二：

测量次数	1	2	3
EC（单位：米）	14.4	13.8	12.5
β	1°24′	2°16′	1°56′
计算得出河宽 （单位：米）

（参考数据：tan1°24′=0.0244、tan2°16′=0.0396、tan1°56′=0.0338、tan76°33′=4.1814、tan71°35′=3.0032、tan65°25′=2.1859）
（2）由（1）表中数据计算：
方案一中河两岸平均宽为米；
方案二中河两岸平均宽为米；
（3）判断河两岸宽大约为米；（从下面三个答案中选取，填入序号）
①390～420        ②420～450         ③350～480
（4）求出方案一的方差S₁²和方案二的方差S₂²，判断用哪种方案测量的误差较小．（精确到1）
