我国高考英语改革发展史
1958—1965年的高考英语试卷采用的主要测试形式有: 英译汉;汉译英;阅读测验;回答问题;用所给单词完成句子。
1977年的高考试题由各省、自治区和直辖市自行命制, 各地在英语试卷中采用的主要题型有: 写出单词的变化形式;用英语回答问题;用动词的适当形式填空;补全句子;英译汉(短文);汉译英;单句填空;阅读短文回答问题;命题作文;语态变化;介词填空;词组造句;句子分析;句型转换;改错;连词成句;英汉单词或词组互译等。
1978年恢复全国统一命制高考试题,当年的高考英语试卷中主要采用了以下测试形式:选择填空;句型转换;汉译英;短文填空;阅读理解;英译汉。
阅读理解试题开始采用提供四个选项的选择题。
1978—1984年期间的高考英语试卷中出现的测试形式有: 选择填空;短文填空;阅读理解(选择、填空、回答问题);汉译英;英译汉;动词填空;正误辨认;拼写单词;改错;句型转换;连词成句;单词辨音;完成句子;词类转换;单词释义;综合填空。
1984年高考全国卷各大题的排列设计如下:1单词辨音;2词类转换;3单词释义;4完成句子;5选择答案;6动词填空;7综合填空;8阅读理解(附加题) ;9综合填空。
1985年,广东省开始进行MET标准化测试的试验工作;同年,原国家教委批准上海市进行高中毕业会考与会考后高考科目改革的试验,上海开始单独命制高考试题。
1989年,MET标准化测试在全国推,按照标准化测试要求命制的高考英语学科试卷基本成形。
以下为1989年全国普通高等学校招生统一考试英语试卷的题型结构:1991年,原国家教委在《关于印发< 高中毕业会考后普通高校招生全国统一考试工作方案(试行) > 的通知》中第一次对高考明确定性:“会考后的高考,在考查基础知识的同时,注重考查能力”。
这一要求成为高考各学科命题的指导思想。
同年,原国家教委有关部门对高考各科试卷设计明确提出了以下要求:1、考试时间由120分钟增加为150分钟;2、分值由10分提高到150分;3、试卷难度由0. 55降低为0.65;4、试卷内容要有新意1992年,原国家教委决定英语学科的考试时间由150分钟减为120分钟,全卷分数仍为150分。

For college students, graduation signals an exciting new beginning. 16 Many students wonder: What do I do now? What career is best for me? Most expert advice on choosing careers boils down to the following points.Knowing YourselfWhat are your interests? Abilities? Skills? 17 The results may surprise you! These can be useful, but they’re not the last word.InvestigatingInvestigating occupations is much more difficult. For most people, there isn’t just one ‘right’ job, but several that could be satisfying. 18 Talk to people who have occupations that interest you. Find out what they like and dislike about their job.19Many people choose their careers because they believe strongly in a particular cause. Some might choose to work in areas like medicine, charity or environmental protection. Some have a strong interest in history or a love for the arts. 20 So in cases like these, the field is often chosen first, rather than the occupation itself. So if you’ve chosen a field, self-assessment will help you find your place in it. Invest some time and effort, and find the right career for you.A. Try a self-assessment quiz.B. Search through books and Web sites.C. Finding your place.D. But it can also bring a lot of uncertainty and confusion.E. Serious research helps narrow the possibilitiesF. Research your chosen field carefully. What work needs to be done? What training is needed?G. Then they might think about education, museums or art production.第二部分英语知识运用(共两节,满分45分)第一节完形填空(共20小题;每题1.5分,满分30分)阅读下面短文,从短文后各题所给的四个选项(A, B, C和D)中,选出可以填入空白处的最佳选项,并在答题卡上将该项涂黑。
高考题选编
高考题选编1、给下面三段文字加上标点符号。
(1978年高考题)(1)实现机械化要靠人的思想革命化有了革命化才有机械化机械化不是一口气吹出来的要通过一番困难奋战才能成功要把揭批四人帮的斗争进行到底要肃清他们的流毒促进人们的思想革命化一个软懒散的领导班子是挑不起这付重担的。
(2)国际形势如何样国内形势如何样涉及政策性的问题该如何办不该如何办应该经常给大伙儿讲讲但是从来不讲这岂不让大伙儿败兴。
(3)白天战士们坚守住差不多占据的阵地夜里战士们向敌人发起新的进攻。
答案:(1)实现机械化(也可加逗号)要靠人的思想革命化。
有了革命化,才有机械化。
机械化不是一口气吹出来的,要通过一番困难奋战才能成功。
要把揭批“四人帮”的斗争进行到底,要肃清他们的流毒,促进人们的思想革命化,一个“软、懒、散”(这三个字不加引号不算错)的领导班子,(也可不加逗号)是挑不起这付重担的。
(2)国际形势如何样,国内形势如何样,涉及政策性的问题该如何办,不该如何办,应该经常给大伙儿讲讲。
(用逗号或分号也不算错)但是从来不讲。
这岂不让大伙儿败兴!(用句号或问号也不算错)(3)白天,战士们坚守住差不多占据的阵地;夜里,战士们向敌人发起新的进攻。
2、给下面两段文字加上标点符号。
(6分)(1979年全国高考题)(1)艺术家要面对人民而不是只面对领导这是不是主张反对领导呢不是的领导在政治上有权提意见要政治挂帅但政治挂帅要紧是看它是香花依旧毒草是否反党反社会主义政治上的敏捷要放在那个方面(2)现代自然科学的进展趋势是一方面学科的划分越来越细另一方面各学科之间互相渗透和交错在学科的进展上互相促进这种情形在物质结构天体演化和生命起源这三大基础理论上表现得专门突出答案:(1)艺术家要面对人民,而不是只面对领导。
这是不是主张反对领导呢?不是的。
领导在政治上有权提意见,要政治挂帅,但政治挂帅要紧是看它是香花依旧毒草,是否反党反社会主义,政治上的敏捷要放在那个方面。
