分析 篇短文主要介紹了3D打印技術(shù)的發(fā)明不僅對(duì)于人們是有幫助的而且如果被壞人利用也有可能是危險(xiǎn)的.
解答 61.A細(xì)節(jié)理解題.根據(jù)文中第三段原句The first 3-D printer was invented in 1986 by an American,Charles Hull.故選A.
62.B歸納理解題.根據(jù)第二段All the user has to do is to design(設(shè)計(jì)) an object on the computer and choose a material(材料) to print in.The printers print in hundreds of different materials including glass,sugar and even skin!When the user presses"print",the 3-D printer spreads the material layer(層) by layer and like magic the object is produced.可知第一設(shè)計(jì)一個(gè)物體,二是選擇材料,三是按下打印按鈕,四打印機(jī)傳輸材料.故選B.
63.C詞義猜測(cè)題.結(jié)合上下文,根據(jù)like them指的是像上文中制造提款機(jī)盜刷器的人一樣的人,故是罪犯,故選C.
64.D推理判斷題.根據(jù)文中倒數(shù)第二段原句It is terrible to think that criminals like them might one day use a 3-D printer to print a gun.有一天罪犯可能會(huì)用3D打印機(jī)打印槍,可知還沒(méi)有打印,故選D.
65.B推理判斷題.根據(jù)文中倒數(shù)第二段原句But like a lot of new technologies,if 3-D printing gets into the wrong hands,it can be dangerous.可知作者認(rèn)為3D技術(shù)也是危險(xiǎn)的,故選B.
點(diǎn)評(píng) 閱讀理解題,需要先讀題,理解清楚題目意思,接著帶著問(wèn)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.
