分析 文章介紹了3D電影電視技術(shù)的應(yīng)用及其原理.介紹了3D與2D的不同之處.另外有也解釋了一些人不適應(yīng)3D電影的原因.
解答 66.B細(xì)節(jié)理解題.根據(jù)文中第一段原句When you watch 3-D movies or TV,you have to wear a special pair of glasses.可以得知,我們觀看3D電視的時候需要佩戴一副特殊的眼鏡,也就是3D眼鏡.故選B.
67.A總結(jié)歸納題.文章第二段主要講述了3D技術(shù)的原理,以及我們的眼睛是如何看到立體的實物的.結(jié)合第二段中的原句Our eyes send the two images to our brain,and the brain puts them together.The small difference between the image from the right eye and the image from the left eye allows us to see depth.可以得知我們的左右眼從不同的角度看到事物,我們的眼鏡把兩個圖象傳回我們的大腦,大腦經(jīng)過分析把圖象合二為一,左右眼看到的圖象的細(xì)微的區(qū)別,可以使我們的眼睛看出深度.故選A.
68.D根據(jù)劃線詞出現(xiàn)的原句Because the pupils of a person's eyes are about 6.5cm apart.句中出現(xiàn)了of,表示一種從屬的結(jié)構(gòu),即the pupils 屬于a person's eyes,翻譯的時候從后往前翻譯,也就是人眼中的pupils距離是6.5厘米,可以推導(dǎo)出pupils在這里指的是人的瞳孔.故選D.
69.A細(xì)節(jié)理解題.根據(jù)文中第四段原句While watching 2-D films,we don't have to wear the special glasses.We see the pictures in two dimensions,each eye get the same information.可以得出當(dāng)我們觀看2D電影時,我們不需要帶特殊的眼鏡.我們看到的是二維的畫面,每個眼鏡得到了同樣的信息.故選A.
70.C分析判斷題.根據(jù)文中倒數(shù)第二段中的原句It uses two film projectors.One projects a left eye image and the other projects a right eye image.可以得知,3D電影需要兩個電影放映機(jī),一個負(fù)責(zé)放映左眼看到的圖象,另一個負(fù)責(zé)放映右眼看到的圖象.故C的表述是正確的.
點評 本文是一篇科普知識文章.介紹了3D電影電視技術(shù).文章中出現(xiàn)很多不常用的生詞,需要考生結(jié)合自己對3D技術(shù)的感受來理解.閱讀理解題,需要先讀題,理解清楚題目意思,接著帶著問題去文章中尋找、推斷答案.把握好細(xì)節(jié),注意推敲才能保證正確率.
