教育类： 第1组：通才VS专才 （6，14，96，116） A nation should require all of its students to study the same national curriculum until they enter college. 在进行大学教育以前，国家应该要求所有的学生学习统一的国家课程。 （13，46，70，102，112，140） Universities should require every student to take a variety of courses outside the student's field of study. 大学应该要求每个学生选修自己专业以外的各种学科。 （24，29，52） The best way to teach is to praise positive actions and ignore negative ones. 教育的最佳方式是赞扬积极的行为，忽视消极的行为。 37 Society should identify those children who have special talents and provide training for them at an early age to develop their talents. 社会应该甄别那些天资聪颖的孩子，并且年幼的时候就开始提供训练培养它们的才能。 54 In order to become well-rounded individuals, all college students should be required to take courses in which they read poetry, novels, mythology, and other types of imaginative literature. 为了成为全面发展的个体，应该要求所有的大学生选择可以阅读诗歌、小说、神话等想象力文学的课程。 （82，97，100，124） Colleges and universities should require their students to spend at least one semester studying in a foreign country. 学院或大学应该要求学生在国外至少留学一个学期。 142 Claim: Colleges and universities should specify all required courses and eliminate elective courses in order to provide clear guidance for students. Reason: College students—like people in general—prefer to follow directions rather than make their own decisions. 结论：为了给学生提供一个明确的方向，学院和大学应该指定所有的必修课程，移除选修课程。 原因：和大众一样，大学生更喜欢按部就班，不喜欢自己做决定。

三年高考试题分类汇编：名著阅读（2017-2019年) 【2019年高考】 一、【2019年高考江苏卷】下列有关名著的说明，不正确的两项是（5分）（选择两项且全答对得5分， 选择两项只答对一项得2分，其余情况得0分） A．《三国演义》中，张飞在长板桥上睁圆环眼厉声大喝，吓退曹兵，然后迅速拆断桥梁，以阻追兵，可见张飞十分勇猛，又很有智谋。 B．《家》中，许倩如倡导女子剪发，带头剪掉自己的辫子，还以梅的遭遇来激发琴拒绝包办婚姻，鼓励琴做一个跟着时代走的新女性。 C．《狂人日记》中，狂人说将来的社会“容不得吃人的人”，最后喊出“救救孩子”，作者借此表达了对社会变革的强烈渴望。 D．《欧也妮·葛朗台》中，夏尔在父亲破产自杀后，不愿拖累心上人安奈特而写了分手信给她，这一良善之举让偷看信件的欧也妮发誓要永远爱他。 E．《老人与海》中，圣地亚哥经过生死搏斗最终将大马林鱼残骸拖回港口，有游客把它当成了鲨鱼骨，这一误会让小说结尾更意味深长。 【答案】AD 【解析】本题考查识记和理解名著的能力。解答本题，平时一定要熟读名著，识记其中的人物和情节。对于大纲要求的篇目，有时间时就要反复读，只有熟到一定的程度，类似题目才能应对自如。A项，“迅速拆断桥梁”“有智谋”错误。如果不拆断桥，曹军害怕其中有埋伏不敢进兵。现在拆断了桥，曹军会料定张飞心虚，必定前来追赶。故A项错误。D项，“这一良善之举让偷看信件的欧也妮发誓要永远爱他”表述错误。欧也妮发誓要永远爱夏尔的原因不止是这一点，还有信中夏尔表达的对欧也妮的好感和赞美。故D项错误。B、C、E项正确。故选AD。 二、【2019年高考江苏卷】简答题（10分） （1）《红楼梦》“寿怡红群芳开夜宴，死金丹独艳理亲丧”一回中，群芳行令，宝钗摇得牡丹签，上云“任是无情也动人”。请结合小说概括宝钗的“动人”之处。（6分） （2）《茶馆》第三幕，在得知来到茶馆的“老得不像样子了”的人是秦仲义时，王利发对他说：“正想去告诉您一声，这儿要大改良！”这里的“大改良”指的是什么？这句话表达了王利发什么样的情感？（4分）
