What is 3D printing? | 3D printing is a process of making three-dimens ion objects out of a digital file. An object created with 3D printing (71)consistsof a number of layers of material. |
How does 3D printing (72)work? | The first (73)stepis to make a virtual design of your (74)desire\wanted\targetobject. A(75)prepared3D model is slictxl into a hujzc number of layers with software or some (76)toolfor a certain 3D printer. The sliced model is (77)fedto a 3D printer The 3D printer (78)forme\makesthe layers into an entire object step by step. |
What else do you need to know? | The (79)sizeof what you intend to make is a factor in your choice of a 3D printer, Prim speed is associated with print (80)quality. |
分析 本文主要給我們講述了3D打印機的工作原理以及如何使用它.
解答 71.consists 題解題.第三段中"..an object is created by laying down successive (連續(xù)的 ) layers of material until the object is created."這句話告訴我們,3D打印機打印出來的物體是由多個層次的材料組合而成的.由..組成:consist of
72.work 細節(jié)題. 閱讀文章第四段到第八段,這部分在講述3D打印機是如何工作的
73.step 細節(jié)題. 第四段中3D printing starts with making a virtual design of…由此可知,making a virtual design of…是3D打印的第一個步驟
74.desired/Wanted/target 細節(jié)題.第四段中‘…the object you want to create.'即…所想要打印的物件,因此可以用wanted desired 或者target 作定語來修飾object
75.prepared 推理題.第五段中"You will have to prepare a 3D model before it is ready to be 3D printed.."告訴我們,打印前要先準備3D模型,然后再將其切割.題中概述里用prepared 作定語來修飾3Dmodel,與原意吻合.
76.tool 細節(jié)題.第五段末說明切片是通過軟件實施的,第六段進一步說明有的3D打印機通過某種切片工具( a certain slicing tool)來進行切片.題中的some與文中的certain同意.故用tool單數形式.
77.fed 細節(jié)題.由七段"…you are ready to feed it to your 3D printer"轉換成被動語態(tài)
78.forme/makes 細節(jié)題.該題是對第八段的概括.即3D打印機逐步將許多的層片組成一個完整的物體.由此得出答案
79.size 細節(jié)題.根據文中內容,consider how big the objects you might want to create 考慮你要創(chuàng)造的物體的大小,即尺寸
80.quality 細節(jié)題.根據文中內容,As with ordinary printers,print speed also depends on how well it prints.打印速度和你的打印質量是密切相關的
點評 題目涉及多道細節(jié)理解題,做題時結合原文和題目有針對性的找出相關語句進行仔細分析,推理判斷題也是要在抓住關鍵句子的基礎上合理的分析才能得出正確答案,切忌胡亂猜測,一定要做到有理有據.
