  GRE数学练习题及解析:

  The curvature of a circle is defined to be the reciprocal of the radius of the circle.

  A. The curvature of a circle with circumference 35π

  B. The curvature of a circle with circumference 36π

  题目翻译:圆的曲率的定义是圆的半径的倒数

  A.周长是35π的圆的曲率

  B.周长是36π的圆的曲率

  解答:curvature 曲率

  reciprocal 倒数

  radius 半径

  circumference 周长

  曲率是半径的倒数, --> 曲率和半径是反比关系, 半径和周长是正比关系, 所以曲率和周长是反比关系。周长越大,曲率越小~

  题中 A 的周长小,所以曲率大

  考点:对于单词的识认能力,对于新的概念的接受与学习能力。

  难点:应该跟着出题老师的思路走,在见到曲率这一新概念是应该能够立刻形成题中所要求的曲率与半径的数量关系。

  GRE词汇备考资料:

  1.antagonistic /æn,tæɡə’nɪstɪk/ adj. 敌对的;对抗性的

  【解词】ant-=anti-=against;agon-=struggle,挣扎;因此这个词的根本含义是“与敌对方挣扎的”,引申为“敌对的,对抗性的”。

  【例句】He was antagonistic to the government's reforms. 他对政府的改革持对抗态度。

  2.skeptical /‘skɛptɪkl/ adj. 怀疑性的,好怀疑的

  【解词】skep-=scop-=watch,看。怀疑,即上下打量。

  【例句】Not all theory that we read in this course is skeptical. 我们在这门课中提及的理论不全是怀疑性的。

  3.moderate /‘mɑdərət/ adj. 中等的, 适度的;温和的; 有节制的

  【解词】源自词根mod-=mode,模式,符合普通模式的,引申为“中等的,适度的”。

  【例句】Moderate exercise will benefit you. 适当的锻炼对你有好处。

  4.aggravate /‘æɡrəvet/ vt. 使恶化, 使更严重

  【解词】agg-=强调;grav-=heavy(如gravity 重力)。因此aggravate 表示“使恶化”。

  【例句】If he aggravates me any more I shall punish him. 如果他再惹我生气,我就要惩罚他。

  GRE写作备考资料:

  The following is a letter to the editor of the Atticus City newspaper

  "Former Mayor Durant owes an apology to the city of Atticus. Both the damage to the River Bridge, which connects Atticus to Hartley, and the traffic problems we have long experienced on the bridge were actually caused 20 years ago by Durant. After all, he is the one who approved the construction of the bridge. If he had approved a wider and better-designed bridge, on which approximately the same amount of public money would have been spent, none of the damage or problems would have occurred. Instead, the River Bridge has deteriorated far more rapidly over the past 20 years than has the much longer Derby Bridge up the river. Even though the winters have been severe in the past several years, this is no excuse for the negligence and wastefulness of Durant."

  Sample Essay

  The author of this letter concludes in his or her argument that former Mayor Durant should apologize to the city of Atticus because he is at fault for damage that has occurred over a twenty-year time span to the River Bridge. The author also blames Mayor Durant for long-time traffic problems on the bridge, stating that Durant actually caused these problems twenty years before because he approved the construction of the bridge and did not approve a wider and better-designed bridge. The arguer may have a personal vendetta against Mayor Durant but the elements stated in the argument do not support such an accusation.
