中考英语阅读理解解题技巧：猜词
在阅读的时候，常常会遇到一些生词，影响我们的阅读速度，其实大部分生词的意思都可以通过上下文的关系猜出来，下面就介绍一些猜词的技巧：
1. 通过因果关系猜词
通过因果关系猜词，首先是找出生词与上下文之间的逻辑关系，然后才能猜词。有时文章借助关联词(如because ，as ，since ，for ，so ，thus ，as a result，of course，therefore 等等表示前因后果。例如：You shouldn't have blamed him for that，for it wasn't his fault.通过for 引出的句子所表示的原因(那不是他的错，可猜出blame 的词义是" 责备" 。
2. 通过同义词和反义词的关系猜词
通过同义词猜词，一是要看由and 或or 连接的同义词词组，如happy and gay，即使我们不认识gay 这个词，也可以知道它是愉快的意思；二是看在进一步解释的过程中使用的同义词，如Man has known something about the planets
Venus ，Mars ，and Jupiter with the help of spaceships. 此句中的Venus(金星、Mars(火星、Jupiter(木星均为生词，但只要知道planets 就可猜出这几个词都属于" 行星" 这一义域。通过反义词猜词，一是看表转折关系的连词或副词，如but ，while ，however 等；二是看与not 搭配的或表示否定意义的词语，如：He is so homely ，not at all as handsome as his brother.根据not at all...handsome我们不难推测出homely 的意思，即不英俊、不漂亮的意思。
3. 通过构词法猜词
在阅读文章时，我们总会遇上一些新词汇，有时很难根据上下文来推断其词意，而它们对文章的理解又有着举足轻重的作用，此时，如掌握了一些常用的词根、前缀、后缀等语法知识，这些问题便不难解决了。
4. 通过定义或释义关系来推测词义
例如：But sometimes，no rain falls for a long，long time. Then there is a dry period，or drought. 从drought 所在句子的上文我们得知很久不下雨，于是便有一段干旱的时期，即drought ，由此可见drought 意思为" 久旱" ，" 旱灾" 。而a dry period 和drought 是同义语。这种同义或释义关系常由is ，or ，that is，in other words，be called或破折号等来表示。
5. 通过句法功能来推测词义
例如：Bananas ，oranges ，pineapples ，coconuts and some other kind of fruit grow in warm areas. 假如pineapples 和coconuts 是生词，我们可以从这两个词在句中所处的位置来判断它们大致的意思。从句中不难看出pineapples ，coconuts 和bananas ，oranges 是同类关系，同属fruit 类，因此它们是两样水果，准确地说，是菠萝和椰子。
6. 通过描述猜词
描述即作者为帮助读者更深更感性地了解某人或某物而对该人或该物作出的外在相貌或内在特征的描写。例如：The penguin is a kind of sea bird living in the South Pole. It is fat and walks in a funny way. Although it cannot fly，it can swim in the icy water to catch the fish.从例句的描述中可以得知penguin 是一种生活在南极的鸟类。后面更详尽地描述了该鸟类的生活习性。

Students: Class 4 Grade 3 Teacher: Lai Ruiwen 一教学分析 1.教学内容简述 该课是一堂专项阅读训练课，具体介绍在高中英语阅读理解中的猜词技巧。―猜测词句意义‖题型在高考阅读中占有一定的份量，每年的高考题中有2-3题，也就是每篇阅读基本上有1题，占了一定的份量。而我们学生在这方面的技能显得薄弱，猜词能力比较差，猜词没有具体的系统的方法，因此，针对此题型的训练就显得很有必要。在必要时，做些语法分析，通过词与词的关系，确定其词性；有时根据常识和生活经验或构词法知识，完全可以对那些从未见过的生词的词义作出正确的推测。做这种题时，特别要注意的是，对于那些我们熟悉的词千万不要妄自、草率下结论，一定要结合上下文判断它在文中的意思。 2 教学对象分析 高三的学生到了高三下学期，积累了一定的词汇量，具备了一定的语篇分析能力，通过一定的练习，掌握了一些阅读理解解题技巧，但是学生普遍基础薄弱，句子分析能力差，不知道联系上下文，阅读能力实属一般，很多同学甚至都是凭感觉在做题，并无系统的解题方法。因而，希望通过此节课使学生的阅读理解能力有所提高。 二．教学目标分析 1.

Her task： to destroy the ships supplies from the United Statesto war-tornEngland. The British had feared such a task. No warship they had could match theBismarckin speed or in firepower. TheBismarckhad eight 15-inch guns and 81 small guns. She could move at 30 nautical(海上的) miles an hour. She was believed to be unsinkable. However, the British had to sink her. They sent out a task force headed by their best battleship Hood to hunt down theBismarck. On May 24, the Hood found theBismarck.

高考英语阅读理解的猜词技巧 猜测词义，是指在阅读过程中根据对语篇提供的信息、行文逻辑、背景知识及语言结构等的综合理解去猜测或推断某个生词、难词、关键词的词义。英语词语的意义非常丰富，语境不同，词义也就不同。所以解决此类题目要掌握一定的猜词策略。 I.根据上下文语境进行猜测 任何一篇文章中的句子在内容上都不是绝对孤立的，都跟句子所在的段落及整篇文章有关。利用上下文提供的情景和线索，进行合乎逻辑的综合分析而推测词义，是阅读过程中的一大关键，也是高考的热点。如： 例1.(2002年全国卷，B篇)“Organic produce is always better，”Gold said，“The food is free of pesticides(农药)，and you are generally supporting family farms instead of large farms. And more often than not it is locally(本地)grown and seasonal，so it is more tasty.”Gold is one of a growing number of shoppers buying into the organic trend，and supermarkets across Britain are counting on more like him as they grow their organic food business 62.What is the meaning of “the organic trend”as the words are used in the text？ A.growing interest in organic food B.better quality of organic food C.rising market for organic food D.higher prices of organic food 例2.(2003年全国卷,C篇)Fermat's Last Theorem(定理).First put forward by the French mathematician Pierrede Fermat in the seventeenth century，the theorem had baffled and beaten the finest mathematical minds，including a French woman scientist who made a major advance in working out the problem，and who had to dress like a man in order to be able to study at the Ecole Polytechnique. 65.Which of the following best exp lains the meaning of the word “baffle” as used in the text？ A.To encourage people to raise questions. B.To cause difficulty in understanding. C.To provide a person with an explanation. D.To limit people's imagination. 例3.If he thinks he can invite me out, he is all wet. I don’t like to be with him. A. drunk B. sweating C. happy D. mistaken 练习：1.A deaf and dump guy went into a hardware store to ask for some nails. 2. The climate of the west coast is the most moderate in Canada, summers are cool and fairly dry and winters are mild, cloudy and wet. Even in mid-winter, the temperature is usually above freezing. 3. All the houses in the city collapsed during the earthquake. 4. For people who live within a stone’s throw from the office to be late to work is unforgivable. 5. The conflagration was so fierce that with just a few second one could see towering flames where the house had stood and the smoke which filled the sky could be seen for miles and miles. （二）根据定义或解释猜测词义 有些阅读文章，尤其是新闻报导及科普类文章中的有些生词，往往在其后有对该词进行解释说明性的短语或句子，如to be, that is , mean, stand for, namely, to refer to, to mean ,in other
（英语）中考英语阅读理解专项训练及答案 一、英语阅读（日常生活类） 1．阅读下列短文，从每题所给的A、B、C三个选项中选出最佳答案。 If you look at the top of your phone, you'll usually see a little symbol that says 3G or 4G. The "G" stands for the "generation" （代）of your mobile network. But the symbols will become things of the past after 5G networks fully arrive. On March 30, Shanghai vice-mayor Wu Qing made the first 5G video call on a Huawei Mate X Smartphone. Shanghai has also become the first city in China to start testing 5G networks. About 100 times faster than 4G networks, 5G will let people download and upload data（数据） faster than ever before. But 5G won't just bring faster mobile internet. People can use it for many other things as well. For example, 5G will help to make self-driving cars safer. Today's self-driving test cars have one problem-lag（延迟）. When the car "sees" an obstacle（障碍物）, it sends this information to a data center and receives instructions, However, it will be some time before it sends and receives this information. With this kind of lag, the cars might crash because they don't receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer. 5G could also be used to power the internet of things （IoT）, that is, a large online network that connects all things and people. Fast internet speeds will be the key to developing this technology. The IoT could be used in a lot of ways. For example, with IoT, your refrigerator could automatically （自动地） place an order online for eggs when it finds that there are no eggs left inside. （1）Which city was 5G tested for the first time? A. Beijing. B. Shanghai. C. Shenzhen. （2）What can we infer（推测） according to the passage?. A. 5G is widely used in China now. B. 5G networks will make our lives more convenient. C. There are no symbols at the top of our phones. （3）The writer uses self-driving cars as an example to . A. explain how 5G's fast speed can be helpful B. warn about the possible dangers of self-driving cars C. explain how self-driving cars work （4）What is IoT according to the passage? A. A robot that can do housework. B. An online store where you can buy anything. C. A large online network that connects things and people. （5）Which sentence is right according to the passage? A. 5G will help us buy eggs quickly. B. Robots can help us buy eggs online. C. Our refrigerator can order eggs online for us. 【答案】（1）B
