Question

5．Some wonderfully creative uses of X-rays have been in the world of art．But the m ost impressive one is to uncover what has bee n covered up．Details unfolded by an X-ray of a painting can't be seen any other way．For example，in the past，paintings were often repaired if small pieces of paint fell off the canvas （帆布）． These repairs cannot be seen just by looking at the painting．It takes an X-ray to discover where the repairs have been made．
An X-ray of a painting is one of the best ways to tell if it was created by a famous painter or if it is a forgery．If there is a question as to whether an old master has painted a certain painting or not，X-rays are made and compared to those of paintings that are known to be original．If the brushstrokes （筆跡），for example，are shown to be totally different than in other work done by a certain artist，then the painting is proved to be a fake copy．
Since modern paints are usually made from different materials than paints of hundreds of years ago，the image they leave on an X-ray film looks different．This is another way X-rays can be used to spot a forgery．A modem artist will try to make a forgery look hundreds of years old by painting dirty vamish on it or by using artificial means to get the varnish to look cracked．To the naked eye the forgery may look ol d，but when a careful study of the X-ray image is made，the deception is obvious．
It was common many years ago for an artist to finish a painting，decide it wasn't any good，and paint a completely different picture on top of it．Or artists would paint over others'work-it was their version of recycling．Taking an X-ray is the only way to find out if there is a picture underneath the picture you see with your eyes．Sometimes museums will be more interested in the painting beneath than the one on top，and will restore the older one by having the top layer painstakingly removed．

Answer 1

分析 本文是一篇科教類閱讀，一些有創(chuàng)意的X-ray的應(yīng)用在藝術(shù)上，文章以此展開(kāi)，主要通過(guò)介紹X-ray在油畫辨別偵察方面的作用，說(shuō)明現(xiàn)代科技X-ray是如何以獨(dú)特的方式應(yīng)用于生活．

解答 63．答案：C．主旨大意題．縱觀全文，文章通過(guò)介紹X-ray在油畫辨別方面的作用，就是解釋說(shuō)明現(xiàn)代科技是如何以獨(dú)特的方式應(yīng)用于生活．AD答案都只是X-ray在油畫方面的一個(gè)作用，無(wú)概括性，B沒(méi)提及．故選C．
64．答案：B．細(xì)節(jié)理解題．從第二段An X-ray of a painting is one of the best ways to tell if it was created by a famous painter or if it is a forgery可知 X-ray被用來(lái)藝術(shù)作品的真假．故選B，A答案in the past 與原文不符．故選B．
65．答案：C．詞義猜測(cè)題．根據(jù)本句句意，裸眼看一個(gè)贗品，看似舊的，但只要仔細(xì)研究制作的X-ray影像，其中的端倪就顯而易見(jiàn)．故選trickery．花招．故選C．
66．答案：A．主旨大意題．文章通過(guò)介紹X-ray在油畫辨別方面的偵探作用，故A符合．BC答案擴(kuò)大化，D答案中心詞Techniques表達(dá)錯(cuò)誤．故選A．

點(diǎn)評(píng) 文章所設(shè)試題主要考察細(xì)節(jié)查找，做題關(guān)鍵是找出原文的根據(jù)，認(rèn)真核查題支和原文的異同，常犯錯(cuò)誤有：絕對(duì)化語(yǔ)言，范圍擴(kuò)大或縮小，以偏概全，張冠李戴等．尤其是最后一題選項(xiàng)中設(shè)題運(yùn)用范圍擴(kuò)大來(lái)干擾答題．
