新SAT官方Daily Practice每日一题写作题

The creation of today's animated films, frequently hailed for their lifelike artistry, relies heavily on mathematics. Animators use algorithms, orsequences of mathematical steps, to create, forinstance, the rounded shapes making up an oldman's knobby knuckles or a young girl's bouncy hair.One of the algorithms now considered an industry standard repeatedly subdivides a polygon bysplitting and averaging the midpoint of a line. Developed by Pixar Animation Studio's TonyDeRose, this algorithm exiled the problem of discernible edges of polygons by replacing themwith the seamlessly rounded curves of the parabolas that emerge as a result of the polygonsubdivision process. Innovations such as DeRose's depend on an understanding of appliedmathematics in areas such as geometry, linear algebra, trigonometry, and calculus.

A.NO CHANGE

B.eliminated

C.canceled

D.prohibited

重点单词：

animation [.æni'meiʃən] n. 活泼，有生气，卡通制作

algebra ['ældʒibrə]n. 代数学

artistry ['ɑ:tistri] n. 艺术性;艺术效果;艺术技巧;艺术工作;工艺

emerge [i'mə:dʒ]vi. 浮现，(由某种状态)脱出，(事实)显现出来

indicate ['indikeit]v. 显示，象征，指示v. 指明，表明

appropriate [ə'prəupriət]adj. 适当的，相称的vt. 拨出(款项)

discernible [di'sə:nəbl]adj. 可辨别的

animated ['æni.meitid]adj. 生气勃勃的，栩栩如生的，动画片的

calculus ['kælkjuləs]n. 微积分

答案：B

解析：

Choice B is the best answer because "eliminated" is acontextually appropriate way to indicate that DeRose's algorithm solved the problem of detectable lines.
