高中英语复习课如何上

高中英语复习课如何上 在传统的英语复习课中，老师肯定比平时更忙。一是课前要忙于准备大量的课件，二是课中还要高速、大容量地满堂灌。课前课中皆辛苦，苦来苦去苦自己，这又何苦呢？其主要的原因就是没有转变复习课的角色和没有改变复习的方式方法。如果能在这两个方面尝试同时改变的话，感觉和效果就完全不同了。 1.复习课的几种类型：1）单元复习课2）期中、期末考复习课 2.复习课的主要内容：1）重点词汇（话题重点词汇、重点动词、 重点形容词、重点名词、重点副词、常用高频词） 2）重点短语：（动词短语、介词短语、形容词短语、其它短语）3）重点句型（结构、特征、关键词、使用场合）4）语法（功能、特征、使用场合） 3.复习课的基本思路： 以教师为主导，以学生为主体，分类复习（输入），巩固练习（初步输出），综合练习（高级输出） 4.复习课的基本操作程序： 1）充分利用学生资源，以学生为主体，以小组合作复习为基本活动方式：由于复习的内容都是学生学过的，所以老师完全没有必要再简单地重复所学的内容。首先要转换角色，让学生来充当复习课的主角，让学生承担复习课的责任。要让每个学生都充分认识到：复习与考试都是自己的事，自己的事要尽量由自己去做。其次，要改变复习的方式。复习的主要活动方式是从个体过渡到复习共同体（合作学习小组）。 2）明确复习主要内容、考试题型和复习时间安排，指导科学有效的复习方法，提供简要的操作（练习设计、考试题型）示范：一是明确复习课的重点内容，二是合理安排复习课的时间（参考时间：学生个体复习归纳（2课时）；小组组内交流、改进（1课时）；全班复习成果展示（1课时），三是为学生提供可以具体操作的复习方法与示范（表格归纳法、思维导图法、结对比较法、分类汇总法等）以及练习、考试题型示范。 3）学生个体尝试自主完成基本任务（基础知识部分复习任务：重点词汇、短语、句型、语法分类整理归纳）（个别学困生也可以与同伴合作完成） 4）小组合作完成拓展性或挑战性复习任务 小组合作设计基础测试常见题：

高二下学期期末考试英语试题 第二部分：阅读理解（共两节，满分40分） 第一节（共15小题；每小题2分，满分30分） 阅读下列短文，从每题所给的四个选项（A、B、C、D）中，选出最佳选项。 A Hotel rooms come in a variety of styles and price ranges. Despite differences m decoration and price, one thing most hotels have in common is a set of rules. Failure to obey these rules can result in fees or fines to cover hotel room damages, removal from the hotel or possibly even arrest. Smoking Some hotels are completely non-smoking. Some hotels designate smoking and non-smoking rooms. If you smoke in a non-smoking room, you will likely be fined hundreds of dollars and possibly asked to leave. Number of Guests Most regular hotel rooms are designed for two adults. If you have more than two people staying in the room, the hotel will likely charge an additional fee for each extra guest, though some hotels let children stay free. Do not put more than four adults in the room unless the hotels policy permits that many people. Or you might be fined or removed from the hotel Hotel Reservations Requirements Most hotels require a major credit card to reserve the room. You can pay cash at the end of your stay, but do not be surprised if there is a temporary charge on your card for a few days after your stay. Most hotels authorize a security deposit on your card to cover any possible damages to the room. Once the hotel confirms that the room is undamaged and that you do not break any hotel policies, your security deposit will be refunded. Breaking the Law You cannot break the law in your hotel room, just as you cannot break the law in your own home or in public. Do not do drugs or commit any other criminal act in the hotel room. If you do, you will likely be arrested. Noise Most hotels have a noise policy you must obey. If you are being too loud you will usually get a warning. If the noise continues and more complaints are issued, you will likely be kicked out of the hotel, regardless of what time it is. 21. What is the main purpose of this passage?

高二英语的期末复习计划-学习计划.

高二英语的期末复习计划-学习计划 2020-04-09 期末考试即将来临，为了更好的复习迎考，外语组全体教师通过讨论，针对学生的实际情况，结合考试的各个题型，特制定期末复习指导计划如下： 一、考试的第一个题型是听力题。 我们每周力争做到有三次听力专项训练，要有质量，有效率。指导学生在听时，要排除外界可能出现的各种干扰，将整个身心投入到解题中，要充满自信和勇气，如做一道题后仍在回想刚才所听的对话，考虑自己的'选择是否正确，势必贻误更多机会，造成后面的题目无法听懂。其次，要想听得懂，必须自己读的准，在记单词、读课文时，要求学生大声朗读，注意语调、连读、重读、弱读。 二、单项选择题。 单项选择是通过设计特定的语言情景，在考查语法、词汇和习语知识的同时，考查学生对语言的初步运用能力的常规题型。指导学生在做此题时，用以下几条思路： A、读出暗示的语言信息，抓住关键词句。 B、利用排除法，各个击破。 C、认真推敲，在比较中选出正确答案。 D、结合语法知识，注意句子结构。 E、分析句子，排除思维定式。 F、注意英语习惯表达，排除母语干扰。此外，要求学生建立一个错题集，也就是记录错题的本子，积极总结，考试前看看容易错的题，提高自己做题的正确率。 三、完型填空题。 有以下几个解题步骤指导学生做此类题型： 首先要重视首句，把握开篇。其次要速读全文，掌握大意。如速读一遍后仍抓不住中心，再读一遍，直到明白大意，掌握梗概，总体把握全文内容、结构、时态、语态变化、情节的展开、结果的形成，然后再答题。 四、阅读理解题。

英语阅读理解是一个复杂而综合性强的思维过程，在这一过程中，我们要通过视觉去辨认读物中的词语，寻找理解的线索，准确地掌握有效信息，对阅读的内容进行总结归纳，做出正确的推断。完成这一思维过程，需有较强的阅读能力，阅读面要广。只有通过大量的阅读，才能准确地把握词语的作用。此外，还要帮助学生纠正不良的阅读习惯，例如反复阅读，低声阅读或注意力不集中等，这些习惯会对学生产生负面影响，大大妨碍阅读的效率。 五、翻译和写作。 翻译和写作是相辅相成的，翻译做得好，就不会差。各年级备课组成员根据每个单元的重点词汇，每人负责一个单元的翻译训练命题，让学生每天坚持做5-10句翻译，要求学生尽量把做过的句子背出来。同时加强写作指导。作文要想得高分有四条对策： 1、写好开篇交待句和末尾总结句，增强文章的照应性。 2、写好常识性语句，增强文章的连贯性。 3、巧用过渡性词汇，增强文章的逻辑性。 4、巧用高级语法词汇，提高文章的表达档次。 把本学期所学的重点语法和词汇归类整理，编出针对性强的复习卷给学生进行训练，备课组成员每人负责出一套卷。此外各年级以备课组为单位，针对学生的实际情况，对如何进行具体的期末复习进行讨论，并于6月12号前制定出可行的计划，复习课按计划进行。

高一英语期末复习及答案

1 高一英语下学期期末综合测试题 卷一 I. 阅读理解： A. Do you know about Dolly, a famous sheep? She was created by cloning more than ten years ago in Scotland. Cloning is famous throughout the world. It is an experiment to make an animal that is exactly like its parent. So far, scientists have cloned rabbits, sheep, cows, mice, pigs and some other animals. But what is used in cloning? It’s DNA. There is DNA in most living things, including human beings. Your DNA is the same in every part of your body. For example, your fingernails have the same DNA as your hair. Y ou have your own DNA, which is similar to your parents’ , but not exactly the same. However, Dolly’s DNA is exactly the same as that of the sheep she was cloned from. No doubt cloning can help save those animals in danger. And it can also benefit human beings. The cloning technology has been used in human organs. With its help, scientists are able to explore more ways to treat many serious diseases such as heart disease, AIDs and cancer. However, cloning could be used in some ways to harm society. All governments should make laws to make sure it can be used properly. 1. When and where was Dolly created? A. More than one hundred years ago, in the USA. B. More than fifty years ago, in Scotland. C. More than ten years ago, in Scotland. D. More than fifty years ago, in China. 2. According to the passage, which one hasn’t been cloned by scientist? A. cows B. mice C. rabbits D. giraffe 3. Which of the following is true according to the passage? A. Cloning is an experiment to make an animal that is different from its parent. B. Your our fingernails don’t have the same DNA as your hair. C. Your DNA isn’t exactly the same as your parents. D. Cloning won’t be used in any ways to harm society. 4. The cloning technology____________. A. is not famous throughout the world B. has been used in human organs C. has been used properly D. is useless 5. The best title for passage is ____________ A. Dolly B. Society C. DNA D. Cloning 答案： CDCBD B The new book Harry Potter and the Half-Blood(哈利·波特与混血王子) is warmly welcomed by the children in China. It sells well across China. You can see and hear the advertisements about the book here and there. Why is the book so popular? After reading it, I was attracted(吸引) by the magic world. I can,t help asking: where is our own Harry Potter? China has a long history and colorful culture. However, why are our present books not as good as those foreign ones? Firstly, many children’s books are written for teaching, and they’re not interesting. Reading them, children often have a feeling of being “educated”. Certainly, they don't like them. Secondly, fewer children like the same stories, but most Chinese books are usually the same. They know the ending when they read the beginning. Finally, the writers hardly ever think about children’s needs. First-class Reading, for children should be interesting, and written in their language. 41. Harry Potter and the Half-Blood is a book about________. A. the magic world B. history C. advertisements D. education 42. About our present Chinese children's books, which is NOT right? A. Many of them are not interesting. B. Our writers hardly ever know children’s needs. C. Most of them are the same. D. They are all better than foreign ones. 43. Harry Potter is so poplar, because________. A. it’s the same as Chinese books B. it can lead children into a wonderful world C. it's not written in children’s language D. it has many advertisements 44. Th e Chinese meaning of the underlined phrase “First -class Reading” is_______. A. 第一批读物 B. 一节课的阅读 C. 一流的读物 D.基础的阅读 45. Which is the best title of the passage? A. Ways to read books B. A magic boy, Harry Potter C. Books and advertisements D. Our children need better books ADBCD C Our children and grandchildren may not have a chance to visit many of the most famous places around the world. War, weather, age, traffic and pollution damage these famous places. Looking after these places often costs more than one country can afford. In the early 1970s, world governments decided that if they joined together, they would be able to preserve our history. If every country paid some money, they said, it would be possible to look after important historic places. Also, if they discovered that a monument needed urgent help, they would have money for repairs. For these reasons, countries around the world united to form the World Heritage Organization in 1972. Today, the organization helps to maintain and restore the most important places from our history. However, one of the biggest problems for historic places is vandalism. People sometimes enter the sites and destroy or damage the buildings. At some sites, such as Stonehenge(巨石阵) in England, governments have built high fences to protect the site from vandals. There are many different ideas about how to solve the problem of vandalism. Stone
