四.考研英语到底考什么?(阅读能力) 1.观念转变和方法转变(close reading 细读)考研考察细读、辨别能力。 2.阅读的重要性 3.考研文章类型的分析(来源、内容、体裁) ①来源:西方大学的一二年级课本、西方报刊杂志 ②从内容角度把44篇文章分类:社会科学为主,自然科学为辅,新的趋势是人文科学的文章。 文章的分类: (1) 社会科学(SocialScience) 包括:政治学、经济学、社会学、传播学、教育学、心理学、历史学、人类学、文化学等分析:政治学,因为西方和东方的意识形态存在差异性,避开敏感话题,没有出过;经济学,教育学,传播学,这些主题要关注。 总结:泛读的重点——经济学、教育学、传播学、心理学。 (2)自然科学(Natural Science),纯而有纯的自然科学很少,命题集中在科学史方面。 出题的原则:一般性原则,公正性原则。 总结:泛读自然科学的文章,少读纯自然科学的文章,多读简介科学史的文章。 (2) 人文科学,包括:文学、历史、哲学 (3)文学评论—未来主义诗歌; (4)散文—雄心壮志; (5)散文—我这个人的一段心路历程;(1)讲幽默,题目有迷惑性。 总结:人文科学出题有抬头趋势。 ④从体裁角度把文章分类:议论文、说明文、记叙文、应用文。 多读:议论文、说明文。 ④从语言上,以美国英语为主。突显美国英语与美国文化,应该多了解一些美国的基本概况。最好有一幅美国地图。 4.新大纲中对于阅读理解的总体要求 ①阅读速度: 每篇文章略有增加,但增加不大。要求文章读得更细了,用close reading(细读)的方式击破考研阅读。 比较适合的阅读速度为:45-50/分 ②八点阅读要求: (1)能够抓住文章中的主旨大意、 (2)理解文章中的具体信息, (3)理解概念性的含义(concept), (4)进行有关的判断、推理和引申的能力(解体思路应尽量适应命题专家) (5)根据上下文推测生词含义, (6)理解文章的谋篇结构及段与段、句与句的逻辑关系, (7)理解作者的意图、观点、态度, (8)区分论点和论据 ③新大纲提出的三点要求: (1)词语的概念性含义 (2)理解文章的谋篇结构 (3)区分论点和论据 5.新大纲的特点(3个): ①放慢作题速度(close reading仔细阅读),阅读速度要求我们读得更细更慢了; ②词的变化(passage变成了text),重视文章总体结构的把握,这要求从结构的角度来读文章; ③命题范围没有任何变化。 强调时效性。考研阅读“赶时髦”,与当今形势联系较紧,多看一些时文(经济方面)。

分享 Polls close in eastern Ukraine amid allegations of fraud and double-voting
912726421 2014-5-12 10:52
Donetsk, Ukraine (CNN) -- Polls closed Sunday after voters streamed into polling stations in eastern Ukraine to vote in controversial referendums held by pro-Russian activists eager to declare independence from Kiev, an official said. Voters in the city of Donetsk faced this question on the ballot: "Do you support the Act of Independence of the People's Republic of Donetsk?" The options are "yes" or "no." A similar question is being put to voters in Luhansk. Many of the voters were not on the outdated registration lists but were allowed to vote after showing identification documents. There also seemed to be no system in place to prevent one person from voting at multiple polling stations. A CNN crew saw several people vote twice at one polling station, where the ballot boxes were decorated with new Donetsk independence flags. Photos: Crisis in Ukraine Russian military pride on full display Pro-Russian militants plan to defy Putin GPS: Did Putin plan the Crimea invasion? There was also a report of video showing three men arrested near Slovyansk with boxes of "yes" ballots in their car. But in a Sunday afternoon news conference, the head of the People's Republic of Donetsk Central Election Committee, Boris Litvinov, disputed reports that people were voting twice in some areas. Litivinov said the lines were so long that many people had a hard time voting once, let alone twice. He also denied the report about ballot fraud. Litvinov said there was no reason for pro-Russian activists to cheat because voter turnout was so high. The polls were told to stay open for 14 hours, rather than the usual 12, to allow time to add people to the voter list if necessary, the election committee said, adding that access to the most recent electoral rolls has been barred by Kiev. Litvinov was the official to announce that polls had closed. Results are expected later. Two incidents heightened tensions at polling places Sunday. Rubber bullets were fired into the air at a station in Donetsk, said election committee member Sergey Tretyakov. Tretyakov also said police in Krasnoarmeysk tried to prevent people from voting. The central government in Kiev has declared the polls illegal. Russia's mixed messages The message coming from Moscow on the referendum appears mixed. Russian police officers oversaw voting at a Moscow polling station erected for expat Ukrainians to vote in the Donetsk and Luhansk referendums. But last week, Russian President Vladimir Putin also urged the pro-Russian sympathizers to delay the referendum to give dialogue "the conditions it needs to have a chance." Putin's unexpected call appears to have dented the confidence of some pro-Russian activists. However, representatives of the pro-Russian groups in Donetsk and Luhansk voted to go ahead with it. Meanwhile, in Slovyansk, a Russian government-controlled TV channel was periodically showing a banner along the bottom of the screen that told viewers where they can vote in Sunday's referendum. That channel, Russia 24, is available over the air to residents of Donetsk, who can access it in their homes. The banner listed the location and voting hours and advised voters to bring a passport. The banner was shown only on the Russia 24 channel, not on other channels.
