13.A.Glass art crafts are becoming popular. B.The physical feature of glass. C.Technology made glass bulbs affordable. D.Scientists'dreams cost millions. E.Architectural experiments with glass. F.The wide use of glass. |
Glass,in one form or another,has long been in noble service to humans.As one of the most widely used of manufactured materials,it can be as impressive as a telescope mirror the width of a tennis court or as small and simple as a marble rolling across dirt.The uses of this adaptable material have been broadened dramatically by new technologies.
77.C
Not all the glass technology that touches our lives is ultra-modern.Consider the simple light bulb; at the turn of the century most light bulbs were hand blown,and the cost of one was equal to half a day's pay for the average worker.In effect,the most light bulbs were hand blown,and the cost of one was equal to half a day's pay for the average worker.In effect,the invention of the ribbon machine by Corning in the 1920s lighted a nation.The price of a bulb plunged.
78.B
The secret of the adaptation of glass lies in its interior structure.Although it is hard,and thus like a solid,the atoms are arranged in a random disordered way,characteristic of a liquid.In the melting process,the atoms in the raw materials are disturbed from their normal position in the molecular (分子) structure.This looseness in molecular structure gives the material what engineers call tremendous"formability",which allows technicians to tailor glass to whatever they need.
79.A
The use of glass as art,a tradition dates back at least to Roman times,is booming.Nearly everywhere,it seems,men and women are blowing glass and creating works of art."I didn't sell a piece of glass until 1975,"Dale Chihuly said,smiling.For 18years he has become one of the most financially successful artists of the 20th century.He now has a new commission,a glass sculpture for the headquarters building of a pizza company---for which his fee is half a million dollars.
80.E
Today,scientists continue to experiment with new glass mixtures and building designers test their imaginations with applications of special types of glass.A London architect,Mike Davies,sees even more dramatic buildings using molecular chemistry."Glass is the great building material of the future,"he said.Think of how the tall buildings in New York could perform a symphony of colors as the glass in them is made to change colors instantly.Mike Davies's vision may indeed be on the way to fulfillment.
分析 玻璃,以一种或是另一种形式,长久以来高尚的服务于人类.今天光学纤维被用在获得比栽植前任何时刻还小的东西的清晰的图象-甚至是细菌病毒.
解答 76-80 FCBAE
76.F.考查的是上下文的语境理解能力.通过分析第二句As one of the most widely used of manufactured materials,it can be as impressive as a telescope mirror the width of a tennis court or as small and simple as a marble rolling across dirt.可知,这一段主要介绍了玻璃的广泛用途;故选F.
77.C.考查的是上下文的语境理解能力.通过句中and the cost of one was equal to half a day's pay for the average worker.以及最后一句The price of a bulb plunged可知玻璃的价格在下降,常人可以消费得起;故选C.
78.B.考查的是上下文的语境理解能力.通过Although it is hard,and thus like a solid,the atoms are arranged in a random disordered way,characteristic of a liquid可知,说明尽管它是刚性的,并且因而像固体,原子分布却是随意混乱的方式,有液体的特性.这是介绍的玻璃的外部特征;故选B.
79.A.考查的是上下文的语境理解能力.通过开头一句The use of glass as art,a tradition dates back at least to Roman times,is booming可知,这主要描述的是玻璃工艺品的流行,故选A.
80.E.考查的是上下文的语境理解能力.最后一段Today,scientists continue to experiment with new glass mixtures and building designers test their imaginations with applications of special types of glass描述的是玻璃用作建筑业的实验;故选E.
