A kiln (窑) is a type of oven or furnace used to cure (加工处理), harden, or burn certain materials. Depending on which materials are heated in it, a kiln may be square, tunnel shaped, or beehive shaped, and usually made of brick or stone. It may be set as low as sixty-five degrees to cure grain or as high as 3,200 degrees to transform limestone to quicklime (熟石灰).
They have a variety of purposes. The cement (水泥) industry uses revolving kilns to heat and separate raw materials. Bricks, pottery, and china made from clay must be fired, or hardened, in kilns. Certain kinds of coal and wood must be kiln-dried （在窑里烘干的）before they can be used. Hobbyists use small kilns to fire a variety of ceramic (陶瓷) objects.
There are two main types of kilns. A periodic kiln, used to fire certain kinds of delicate china, is raised to a high temperature and then completely cooled before its contents are removed. A continuous, or tunnel kiln contains several chambers, or zones, which heat, bake, and cool a product. Stacks of clay bricks move through a tunnel kiln on tracks
Gas, oil, and coal are all used to heat modern kilns But for special jobs, where cleanliness and careful heat（绝热）are important, kilns must be heated by electricity oven though it is more expensive. Small kilns used in the home or in craft shops are also heated electrically because electricity is clean and convenient.
When ancient people discovered that heat hardened some materials, they were able to make durable household objects such as jugs and bowls. Today our museums display many kinds of ancient statues and art objects that have lasted because they had been kiln-dried. They come from lands as far apart as China and Greece.
A. Its temperature may vary.
B. Then they come out, hardened, and cooled.
C. Kilns are used in industry and in craft-making.
D. Kilns have been in use for thousands of years.
E. An electric kiln is a heating chamber used to transform materials.
F. Most manufacturers use whichever material is cheapest in their area.
G. Clay, when heated properly, becomes hard enough to form bowls and plates.
A. It's not a simple matter to determine the nature of talent. B. Sports team owners spend millions of dollars attracting top talent C. The group interaction and its effect drew the researchers' attention. D. Stars apparently do not follow this basic principle of sportsmanship. E. Several recent studies examined the role of talent in the sports world. F. Building up a dream team is more complex than simply hiring the best talent. G. This task interdependence distinguishes baseball from football and basketball. |
Much of the work in today's world is accomplished (完成) in teams. Most people believe the best way to build a great team is to gather a group of the most talented individuals. {#blank#}1{#/blank#} Companies spend millions hiring top business people. Is their money well spent?
{#blank#}2{#/blank#} They focused on football, basketball and baseball. The results are mixed. For football and basketball, adding talented players to a team proves a good method, but only up to the point where 70% of the players are top talent; above that level, the team's performance begins to decline. Interestingly, this trend isn't evident in baseball, where additional individual talent keeps improving the team's performance.
To explain this phenomenon, the researchers explored the degree to which a good performance by a team requires its members to coordinate (协调) their actions. {#blank#}3{#/blank#} In baseball, the performance of individual players is less dependent on teammates. They conclude that when task interdependence is high, team performance will suffer when there is too much talent, while individual talent will have positive effects on team performance when task interdependence is lower. If a basketball star is, for example, trying to gain a high personal point total, he may take a shot himself when it would be better to pass the ball to a teammate, affecting the team's performance. Young children learning to play team sports are often told, "There is no I in TEAM." {#blank#}4{#/blank#}
Another possibility is that when there is a lot of talent on a team, some players may make less effort. Just as in a game of tug-of-war (拔河比赛), whenever a person is added, everyone else pulls the rope with less force.
{#blank#}5{#/blank#}. An A-team may require a balance-not just a players, but a few generous B players as well.
