北京科技大学考博英语题型分析

2015北京科技大学考博英语历年真题 一、招考介绍 从整体上看,由于博士生招生形势的不断发展各院校博士生入学考试的难度越来越大,对考生的外语水平要求也越来越高,特别是听、说能力。攻读博士学位的学生,一方面应该具备坚实的专业理论基础和扎实的科研能力,另一方面还应该具备较高水平的外语能力。 二、北京科技大学考博英语题型 Part1:词汇20题10分; Part2:完型20题10分; Part3:阅读理解5篇25题40分(四篇常规阅读20题30分,一篇用英语解释原文句子5题10分); Part4:翻译20分(英译汉10分,汉译英10分); Part5:作文20分; 三、考博英语必备参考书 育明考博教研部主编,河北大学出版社出版的《考博英语真题解析》和《考博词汇》是考博人必备的两本书。在当当网,亚马逊和全国各大书店均有销售,也可以联系我们直接购买。 四、联系导师 在初步定好考博学校之后,就要和所报考院校中意的老师取得联系,询问是否有招生名额,能否报考,这是我们考博成功的关键第一步。 大多数考生会在九月中下旬与导师取得联系。因为太早,学校里面直博名额什么的还没有确定,报考的导师也不清楚是否有名额;太晚的话,怕别的学生比你早联系就不好了。一般情况下,导师对一个学生很中意的话,后来联系的学生,导师一般也不会答应其报考了。在此说点题外话,联系导师的过程中,如果读研期间的导师有关系,可以尽量利用。如果没有,也没关系,凭着自己的本事也是可以和考博导师很好的沟通的,这就要看自己了。 通常跟导师初次联系,都是发邮件。导师回复邮件的情况一般有几种: (1)、欢迎报考。这种答复最笼统,说明不了问题。我们可以接着努力和老师多沟通,看看具体的进展,避免出现初试之后却没有名额的情况。

北京科技大学考博英语真题常见分词及其解析

北京科技大学考博英语真题常见分词及其解析 一、分词的否定式 分词或分词短语表示否定意义时,将not置于分词之前,不能放在分词之后。 例句:Equipment not conforming to official safety standards has all been removed from the workshop.(2001年第24题) 分析:该句是简单句。not conforming to official safety standards 是分词短语作后置定语修饰equipment。 译文:凡是不符合官方安全标准的设备都已经搬出了车间。 例句:Not having been destroyed by the heavy snow,our houses at last were kept perfect during last winter. 分析:该句是简单句。Not having been destroyed by...在句中作状语表示原因,相当于because our houses had not been destroyed by...。 译文:由于没有遭到大雪的破坏,去年冬天我们的房子最终完好无损。 二、独立主格结构(Absolute Construction) 分词作状语时,分词的逻辑主语要与句子主语保持一致,即句子的主语便是它的逻辑主语,否则就会出现悬垂或荡空结构(前面已讲过),但有时分词有其独立的逻辑主语,即分词的逻辑主语与句子主语不一致,这就是独立主格结构。需要各大院校历年考博英语真题及其解析请加扣扣七七二六七八五三七或二八九零零六四三五一,也可以拨打全国免费咨询电话四零零六六八六九七八享受考博辅导体验。 (一)独立主格结构公式 逻辑主语A+分词(短语)+主B谓 在上述公式中,其中(逻辑主语+分词短语)属于独立主格结构,主谓是
