　　In the atmosphere,carbon dioxide actd rather like a one-way mirror or the glass in the roof of a greenhouse which allows the sun's rays to enter but prevents the heat from excaping.
　　According to a weather expert's prediction,the atmosphere will be 3 warmer in the year 2050 than it is today, if man continues to burn luels at the present rate. If this warming up took place,the ice caps in the poles would begin to melt,thus raising sea level several meters and severely flooding coastal cities.Also，the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere(半球),psooicbly resulting in an alteration of earth's chief food growing zones.
　　In the past,concern about a man - made warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet.But the weather experts are now paying more attention to West Antarctic,which may be affected by a warming on the scale that will possibly take place in the next fifty years from on burning of fuels.
　　Satellite pictures showthat large areas of Antarctic ice are already disappearing.The evidence available suggests that a warming has taken place.This fits the theory that carbon dioxide warms the earth.
　　However,most of the fuel is burnt in the northern hemisphere,where temperatures seem to be falling.Scientists conclude,therefore,that up to now natural influences on the weather have exceeded those caused by man.The question is:Which natural cause has most effect on the weather?
　　One possibility is the variable behavior of the sun.Astronomers at one research station have studied the hot spots and cold spots(that is,the relatively less hot spots) on the sun. As the sun rotates(旋转),every 27.5 days,it presents hotter or colder faces to the earth,and different aspects to different parts of the earth.This seems to have a considerable effect on the distribution of the earth's atmospheric pressure,and consequently on wind circulation.The sun is also variable over a long term:its heat output goes up and down in cycles,the latest trend being downward.
　　Scientists are now finding mutual relations between models of solar weather interactions and the actual climate over many thousands of years ,including the last Ice Age.The problem is that the models are predicting that the world should be entering a new Ice Age and it is not.
　　One way of solving this theoretical difficulty is to assume a delay of thousands of years while the solar effects overcome the inertia(不活动，惰性) of the earth's climate.If this is right,the warming effect of carbon dioxide might thus be serving as a useful counter balance to the sun's diminishing heat.
　　68.It can be concluded that a concentration of carbon dioxide in the atmosphere would ___.
　　　A.mean a warming - up im the Arctic
　　　B.raise the temperature of the earth's surface
　　　C.prevent the sun's rays from reaching the earth's surface
　　　D.account for great changes in the climate in the northern hemiphere
　　69.Although the fuel consumption is greater in the northern hemisphere,temperatures there seem to be falling.This is _______.
　　　A.mainly because the levels of carbon dioxide are rising
　　　B.partly due to variations in the output of solar energy
　　　C.possibly because the ice caps in the poles are melting
　　　D.exclusively due to the effect of the inertia of the earth's climate
　　70.On the basis of their models,scientists are of the opinion that ________.
　　　A.the climate of the world should be becoming cooler
　　　B.the new Ice Age will be delayed by the greenhouse effect
　　　C.the man - made warming effect helps to increase the solar effects
　　　D.it will take thousands of years for the inertia of the earth's climate to take effect

“I grew up on Jackson’s music and I still have all his stuff on My iPod. I think that Michael Jackson will go down in history as one of our greatest entertainers. His brilliance as a performance also was paired with a tragic and in many ways，sad personal life.”

Michael Jackson was a singer，songwriter，dancer and celebrity icon with a vast catalog of hit records and countless awards to his credit. Beyond that，he had transfixed the world like few entertainers before or since. As a solo performer，he had enjoyed a level of superstardom previously known   ——Barack Obama

only to Elvis Presley，the Beatles and  Frank Sinatra.

Michael Jackson was unquestionably the biggest pop star of the 80s’，and certainly one of the most popular recording artists of all time.

Michael Joseph Jackson was born on August 29,1958.The fifth and youngest son of steelworker Joe Jackson，Michael displayed a talent for music and dance from an extremely young age. His father began to organize a family musical group around his three eldest sons in 1962，and Michael joined them the following year，quickly establishing himself as a dynamic stage performer. Dubbed the Jackson 5，the group signed to Motown in 1968 and issued their debut single in October 1969，when Michael was just 11 years old. I Want You Back，ABC，The Love You Save and I’ll Be There all hit number one in 1970，making the Jackson 5 the first group in pop history to have their first four singles top the charts. Later in 1972，Jackson had his first number one solo single，Ben. In 1977，he met producer/composer Quincy Jones for the first time. With Jones producing，Jackson recorded his first solo album as an adult，Off the Wall.

Released（发行） in 1982，the Quincy Jones produced Thriller refined the strengths of Off the Wall：the dance and rock tracks were more driving，the pop tunes and ballads softer and more soulful，and all of it was recognizably Michael. There was no surprise that Thriller was a hit；what was a surprise was its staying power .Jackson’s duet with McCartney，The Girl Is Mine，was a natural single choice，and it peaked at number two；then Billie Jean and the Van Halen track Beat It both hit number one，for seven and three weeks respectively.

Michael Jackson died from heart disease on June 25 at age 50.

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

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.

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.

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.

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.

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.
