D. But 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 equivalent to half a day’s pay for the average worker…………In this way, the envelope of a light bulb is made by a single machine at the rate of 66,000 an hour, as compared with 1,200 a day produced by a team of four glassblowers.
本段一二句话题出现为由大到小,由泛指到具体,本段主旨可以是泛泛而谈的非ultra-modern科技,也可以是具体的light bulb,通过最后一句没有提到此类科技,所以确定主题为后者。
E. The secret of the versatility of glass lies in its interior structure. Although it is rigid, and thus like a solid, the atoms are arranged in a random disordered fashion, characteristic of a liquid………….. This looseness in molecular structure gives the material what engineers call tremendous “formability” which allows technicians to tailor glass to whatever they need.
本段一二末三句话的话题一直保持一致,那么本段主旨极为interior structure导致多样性。
F. 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…………Mike Davies’s vision may indeed be on the way to fulfillment.
首句提出两个话题,但是后文只说了一个,有效话题只是后者。因此本段的话题也就是architect
