高起专英语复习指南 篇1

文言文如何复习?

文言文阅读在成人高考里面不考语法，不考字词，但是有一道划线部分的句子翻译，这道翻译题也只是要求考生能够说出大概意思就可以。

考生在做这道题的时候注意：按照划线部分的标点符号逐一大致译成白话文，不要求字词的完全准确，但是也不可以把它们合并成一个大概意思，用一句话概括，这个占6分。其余两道题主要有：作品里边反映的思想内容和作者的主观评价。

诗歌阅读如何复习?

诗歌阅读一般考的都是唐宋作品，四句诗、八句诗为主，考生首先要了解一些有关诗歌的文体知识。比如说考律诗，大家应该知道律诗是八句，中间四句两句分别对照。如果问其中的两句用了什么修辞手法，就应该不犹豫的写出有对偶。

如果让分析颈联两句的意思，大家应该知道是找五、六句。如果这点知识都错了，就是看懂了，分析错了句子也要丢分。

做病句题应当注意什么?

成人高考病句列出来的是以下几种，这几种是成分残缺或赘余、语序不当、搭配不当、结构混乱、表意不明、不合逻辑。考生要掌握这些病句的类型，能够辨识并修改。从技巧上来说，考生最好看出每种类型常常出现的形式。比如说搭配不当，经常以一个动词带两个宾语，中间往往会有一个“和”字。例如：人们以敬佩的目光注视着和倾听着这位受人尊敬的长者。目光就不能倾听，这种病句总是有一个搭配，有一个不搭配。注意这个“和”字就应该每个都相应的去分析一下，很容易找出这样的病句。

高起点《语文》备考建议

个人觉得从复习来讲，首先要踏踏实实的抓好基本功的落实。这里的基本功、基本知识，一个是对字的正确理解，一个是字音正确的读，还有一个是义。另外建议大家多关注一些成语。因为考试出题，不论是改病句还是其它的也好，往往成语出现频率比较高。因为成语是一个固定的词组，往往能够体现出很多语言现象，所以请大家要把这方面基本落实。除此之外，因为牵扯到后面的知识，就要多关注一下生活。因为现在的作文应该是有一定的现实意义。再有，要联系实际，写出真情实感来。至于分析题，主要是要通过我们的基本课文，通过参加一些考前辅导，来增强自己的语感，也就是语言的感悟能力，能够提炼出文章主要的意思。总之，还是要踏实的下基本功，在考试中没有任何的捷径，只有勤奋才能使大家成功。

高起专英语复习指南 篇2

一、了解书面表达评分原则

充分了解全国高起专成人高考英语书面表达的评分原则, 有利于考生把握作文的得分要点和阅卷的尺度, 对自己的写作起到一定的指导作用。评分原则如下:

1.本题总分为30分, 按5个档次给分。

第五档 (很好) : (25~30分) 完全完成了试题规定的任务。覆盖了所有内容要点;应用了较多的语法结构和词汇;语法结构或词汇方面有些许错误, 但为尽力使用较复杂结构或较高级词汇所致;具备了较强的语言运用能力;有效地使用了语句间的连接成分, 使全文结构紧凑, 完全达到了预期的写作目的。

第四档 (好) : (19~24分) 完全完成了试题规定的任务。虽漏掉一两个次重点, 但覆盖所有主要内容;应用的语法结构和词汇能满足任务的要求;语法结构或词汇方面应用基本准确, 些许错误主要是因尝试较复杂语法结构或词汇所致;应用简单的语句间连接成分, 使全文结构紧凑, 达到了预期的写作目的。

第三档 (适当) : (13~18分) 基本完成了试题规定的任务。虽然漏掉一些内容, 但覆盖所有主要内容;应用的语法结构和词汇能满足任务的要求;有一些语法结构或词汇方面的错误, 但不影响理解; 应用简单的语句间连接成分, 使全文内容连贯。整体而言, 基本达到了预期的写作目的。

第二档 (较差) : (7~12分) 未恰当完成试题规定的任务。漏掉或未描述清楚一些主要内容, 写了一些无关内容;语法结构单调, 词汇项目有限;有一些语法结构或词汇方面的错误, 影响对写作内容的理解;较少使用语句间的连接成分, 内容缺少连贯性。信息未能清楚地传达给读者。

第一档 (差) : (1~6分) 未完成试题规定的任务。明显遗漏主要内容, 写了一些无关内容, 原因可能是未理解试题要求;语法结构单调, 词汇项目有限;较多语法结构或词汇方面的错误, 影响对写作内容的理解;缺乏语句间的连接成分, 内容不连贯。信息未能传达给读者。

0分:未能传达给读者任何信息 ;内容太少, 无法评判;写的内容均与所要求的内容无关或所写的内容无法看清。

2. 评分时 , 先根据文章的内容和语言初步确定其所属档次, 然后以该档次的要求来衡量, 确定或调整档次, 最后给分。

3.词数少于80和多于120的, 从总分中减去2分。

4.评分时 , 应注意的主要内容为 : 内容要点、应用词汇和语法结构的丰富性与准确性, 上下文的连贯性及语言的得体性。

5.拼写与标点符号是语言准确性的一个方面, 评分时, 应视其对交际的影响程度予以考虑。英、美拼写及词汇用法均可接受。

6.如果书写较差 , 以至影响交际 , 那么将分数降低一个档次。

从以上评分原则, 我们可以了解到书面表达侧重的是:要点内容的覆盖率, 篇幅的长短, 语法的准确性、丰富性, 上下文的连贯性, 拼写、标点符号的正确使用, 以及书写的美观程度, 这样考生对阅卷老师心目中的好作文有了全面了解, 写作时便可以有的放矢。

二、书面表达试题特点分析

笔者归纳了2009—2012年全国高起专成人高考英语书面表达试题, 从中可以发现近几年全国高起专成人高考英语书面表达试题的特点:

1.以电子邮件或书信体裁为主;

2.写作试题均有中文或图表提示;

3.写作内容日常化、广泛化;

4.写作的词数要求都是100左右;

5.都是以第一人称书写;

6.以现在时和将来时态为主;

7.电子邮件或书信的开头和结尾都已给出。

三、书面表达解题策略

从书面表达的上述评分原则与题型特点分析, 考生要做好书面表达题, 可按以下解题策略进行:

1.认真审题。考生拿到试题不要慌张, 要花几分钟时间耐心、细心地读题, 包括中文说明、提示、图表、生词等, “注意”事项也要认真阅读, 真正读清楚写作的内容、要求, 以及确定本文的人称、时态等。

2.列出框架。 考生根据所给的中文提示和说明等, 在草稿纸上用铅笔列出几条要点, 也就是写作的基本框架。

3.构思初稿。考生按照自己列出的基本框架, 构思初稿。先运用自己熟悉的、已掌握的、最简单的英语表达方式写出各条要点内容, 切记不能纯粹地把要点翻译就了事, 一定要加入合适的连接词或词组, 这样能够使作文的结构更加紧凑、通顺。

4.落笔书写。考生根据初稿, 用黑色水笔或钢笔把作文誊写到答题纸上, 注意书写规范、字迹清晰, 这样会给阅卷老师留下良好的印象, 在评定档次时会有所考虑。

5.反复诵读。首先通读自己所写的作文 , 对照自己列出的作文框架, 看是否覆盖了所有要点, 评分原则中对要点遗漏的扣分比重较大, 其次细读文章, 看自己所写的短文的标点符号是否运用正确, 单词拼写是否有错误, 语法是否前后一致等。

为提升自己的书面表达水平, 考生还可以从以下方面着手:

1.熟练掌握常用的英语词汇和五个基本句型。

2.加强阅读, 每天坚持看一些简单的英语小故事或新闻。

3.多练习一些模拟试卷中针对性较强的作文 , 切记一定要先自己试着写, 然后查看参考答案, 找出自己的不足之处, 在下次写作中改进。

4.选择一些比较好的书面表达范文, 试着背诵, 在平时练习写作时加以运用。

In ancient times wealth was measured and exchanged in things that could be touched: food, tools, and precious metals and stones、Then the barter system was replaced by coins, which still had real value since they were pieces of rare metal、Coins were followed by fiat money, paper notes that have value only because everyone agrees to accept them、Today electronic monetary systems are gradually being introduced that will transform money into even less tangible forms, reducing it to a series of “bits and bytes”, or units of computerized information, going between machines at the speed of light、Already, electronic fund transfer allows money to be instantly sent and received by different banks, companies, and countries through computers and telecommunications devices、61、Which of the following would be the most appropriate title for the passage?

Passage Three

The water we drink and use is running short in the world、We all have to learn how to stop wasting our limited water、One of the steps we should take is to find ways of reusing it、Experiments have already been done in this field、Today in most large cities, fresh water is used only once, then it runs into waste system、But it is possible to pipe the used water to a purifying factory、There it can be filtered and treated with chemicals so that it can be used again, just as it were fresh from a spring、But even if every large city purified and reused its water, we still would not have enough、Then we could turn to the oceans、All we’d have to do to make use of the seawater on earth is to get rid of the salt、This process is called desalinization, and it is already in use in many parts of the world、71、The way to stop wasting our limited water is to ________、A、do experiments with water B、purify the used water and reuse it

Some people hate everything that is modern、They cannot imagine how anyone can really like modern music;they find it hard to accept the new fashions in clothing;they think that all modern painting is ugly;and they seldom have a good word for the new buildings that are being built everywhere in the world、Such people look for perfection in everything, and they take their standards of perfection from the past、They are usually impatient with anyone who is brave enough to experiment with new or to express himself or the age in materials original ways、It is, of course, true that many artists do not succeed in their work and instead produce works that can only be considered as failures、If the work of art is a painting, the artist’s failure concerns himself alone, but if it is a building, his failure concerns others too, because it may damage the beauty of the whole place、This does sometimes happen, but it is completely untrue to say, as some people do, that modern architecture is nothing、We can’t judge every modern building by the standards of the ancient time, even though we admire the ancient buildings、Technologically, the modern buildings are more advanced、The modern architect knows he should learn from the ancient works, but with his greater resources of knowledge and materials, he will never be content to imitate the past、He is too proud to do that、76、Some people hate everything that is modern because _______、A、they are aged B、they find it hard to accept modern things

C、they take their standards of perfection from the Greek

D、they look at things by the standards of the past77、The writer of the passage thinks that ________、it is true to say artists fail in their work

it is untrue to say artists fail in their work

it is true to say some artists fail in their work

it is true to say only painters fail in their work78、The writer thinks the failure of a building _______、A、means nothing B、concerns others

C、concerns only the artist D、concerns all the people in the world79、The writer thinks that _________、we can’t judge buildings by the ancient standards

发电厂电气部分(高起专) 篇6

1、水力发电厂可分为几类？

答：（1）按集中落差的方式分：堤坝式水电厂、引水式水电厂混合式水电厂；（2）按径流调节的程度分：无调节水电厂、有调节水电厂。

2、为何电流互感器在运行时二次绕组严禁开路？

....答：由磁势平衡方程式：I1N1I2N2I0N0，可知当二次开路时，I2＝0，一次磁势完全用于励磁，使得铁芯严重饱和，且磁通为平顶波（由磁化曲线得）

1）二次电势：e2N2d/dt，对于平顶波，在过零时，会出现成千上万伏的尖顶电势，使得互感器本身、表计、继保、自动装置以及连接导线的绝缘有被击穿的危险，也会危急人身安全。2）（由于铁芯严重饱和），铁芯严重发热，铁片中间、铁芯与一次、二次绕组间的绝缘受热有被破坏的危险

3）剩磁使得误差增大，使得设备磁化。所以电流互感器在运行时二次绕组严禁开路。

二、论述题

1.大电流导体周围钢构为什么发热？其有什么危害？减少大电流导体周围钢构发热，常采用哪些措施？

答：大电流导体周围会出现强大的交变电磁场，使其附近钢构中产生很大的磁滞损耗和涡流损耗，钢构因此发热，若有环流存在，发热还会增多。钢构温度升高后，可能使材料产生热应力而引起变形，或使接触连接损坏。混凝土中的钢筋受热膨胀，可能使混凝土发生裂缝。

为了减少大电流导体周围钢构发热，常采用下列措施：

（1）加大钢构和导体间的距离，进而减弱磁场，因此可降低磁滞和涡流损耗；

（2）断开钢构回路，并加上绝缘垫，消除环流；（3）采用电磁屏蔽；（4）采用分相封闭母线。

2.什么是导体固有频率？导体电动力计算时为什么要考虑振动？什么时候考虑？怎样解决？

答：导体具有质量和弹性，当受到一次外力作用时，就按一定频率在其平衡位置上下运动，形成固有振动，其振动频率称为固有频率。

由于受到摩擦和阻尼作用，振动会逐渐衰减。若导体受到电动力的持续作用而发生震动，便形成强迫振动，电动力有工频和2倍工频两个分量。如果导体的固有频率接近这两个频率之一时就会出现共振现象，甚至使导体及其构架损坏。

凡连接发电机、主变压器以及配定装置中的导体均属重要回路都需要考虑共振影响。

为了避免导体产生危险的共振，对于重要的导体，应使其固有频率在危险范围之外。

3.发电厂的控制方式有哪些？论述其各自的特色。答：

1、主控制室控制方式。早期发电厂单机容量小，常采用多机对多炉（如四炉对三机）的方式，机炉电相设备的控制采用分离控制，即设立电气主控制室、锅炉分控制室、和汽机分控制室。主控制室为全厂控制中心，负责起停机和事故处理方面的协调和指挥，因此要求监视方便，操作灵活，能与全厂进行联系。

2、机炉电集中控制方式。对于单机容量20万及以上的大中型机组，一般将机炉电设备集中在一个单元控制室简称集控室控制。现代大型发电厂，大机组的锅炉与汽机之间采用一台锅炉对一台汽轮机构成独立单元系统的供气方式，不同单元系统之间没有横向的蒸汽管道联系，这样管道最短，投资最少，且运营中锅炉能够配合机组进行调节，便于机组起停和事故处理。

三、计算题

1、某发电机端电压为10.5kV，额定电流为1500A，装有2×（100×8）mm2矩形铝导线，短路电流I28kA，I20kA。继电保护动作时间为0.3S，断路器全断开时间0.2S，正常负荷时母线温度为46°，试计算短路电流热效应和母线的最高温度。（注：温度46°时，16）A0.3510ΩJ/m(4)解：

此母线最高温度未超过允许值，能满足热稳定要求。
