高中英语
必备单词（二）
知识梳理
01
词根词缀记忆法
词根词缀记忆法是最高效的一种单词记忆方法。想要在短时间内记忆大量单词，高中生要采用词根词缀记忆法。很多单词都是由词根词缀组成的，词根词缀就像是汉字的偏旁部首，知道了偏旁部首，我们就能大致知道汉字跟什么有关。英语单词也是一样，知道了词根词缀，我们就算不认识单词，也能大致了解单词跟什么有关。
比如con是一个前缀，表“一起”的意思，tract是个词根，表“拖、拉”的意思，contract表跟对方一起拖、拉，这样的东西就是合同、合约。此外还有很多前缀，如contro表相反的，mis表错误、dis表否定……。
音型结合法
音型结合法也是非常好用的一种方法，这种方法把单词的音与型结合起来，拼写按照音节来拆分，适合长期学英语的同学。比如peach、reach、teach、beach等单词，这些单词当中都有each。each发音为[i：t]。peach 发音为[pi：t]，reach发音为[ri：t]，记住了each的发音，其它相似单词的发音也就记住了。
同类单词记忆法
同类单词记忆法其实非常好理解，就是把相似的单词或者同一类的单词放在一起记忆。比如表示方位的单词：east、west 、south 、north；表星期的单词，Monday、Tuesday、 Wednesday、Thursday、Friday；表季节的单词spring、summer、autumn、winter。记忆单词的时候，同学们把同类单词放在一起记忆，能够加深印象，快速记住同类单词。
联想法
联想法也是很多学生常用的一种单词记忆方法。如果一个单词怎么也记不住，同学们可以使用联想法。联想法就是把单词联想成一个小故事。比如ambulance是救护车的意思，我们可以跟发音 ['mbjlns] 结合起来，联想成：“俺不想死”。再比如scarf是围巾、丝巾的意思，我们可以联想成一个S型的美女围着围巾开着小汽车。
艾宾浩斯遗忘曲线记忆法
艾宾浩斯遗忘曲线记忆法不仅可以用在记忆单词上，还适用各科知识点的记忆。艾宾浩斯遗忘曲线告诉我们：人的遗忘是有规律的，遗忘的进程先快后慢，呈负加速状态。这条曲线告诉我们，想要记住知识点，我们学习之后要频繁的记忆，刚开始复习的频率快一些，慢慢地降低复习频率，这样单词通过多次反复记忆，就深深的记住了。
单词是句子的基础，我们不认识单词，就不知道句子的意思，就可能选错答案。记住英语单词是学习英语的基础。高考之前，高中生要牢记3500单词。为了更快更牢地记住单词，高中生要采用一些单词记忆方法。比如词根词缀法、音型结合法、同类单词记忆法等。每天早晨的时候，同学们可以先记忆一些单词，然后利用琐碎时间巩固记忆的单词，晚上再复习一遍，这样一天当中至少记忆了三遍单词。在多次记忆当中，单词就记住了。
正反意思背单词
看到一个单词的时候，可以联想到它的同义词或近义词，通过对比辨析，掌握它们的用法；看到一个单词的时候，可以联想到它的反义词，一正一反，成双成对，让你一石二鸟，一箭双雕！用这种对比法来记忆单词，印象会更加深刻！
通过句子背单词
孤立地背单词只能是“背了记、忘了背、背了又忘”！所以，一定要通过实用的句子背单词。在句子中记单词才是有生命的单词，才能牢记单词的意思和用法，才能与之建立感情，才会让你刻骨铭心，永难忘怀！更重要的是，通过脱口而出句子来背单词，你不但在积累单词量，更在积累句子量！句子量比单词量更重要！

Noise-cancelling audio instruments have been around for a while now，but one Berlin-based designer believes that blocking “visual noise” is as important，if not more so，as cancelling out unwanted sounds．To this end he has created a simple accessory called the Focus Cap．
Open work spaces definitely have their benefits，but they come with the drawback of offering employees little to no control over visual distractions(干扰)．With so many people around and so much going on，some of us can easily get disturbed by this information overload and lose focus in what’s really important．That’s where the Focus Cap comes into play．
“As we are still cavemen or mammals kept in an unnatural environment，I believe that only by reclaiming(收回) the normal，stress-free human state through simple tools and techniques can we finally release our actual creative potential and create our meaningful work for a brighter future，”says German designer Hannes Greblin，inventor of the Focus Cap．
After looking at other products designed at minimizing visual distractions，Greblin decided that most of them were either too expensive or too uncomfortable to become mainstream，so he decided to go with something much simpler —a simple cap with a retractable visor(可伸缩的帽沿)．
Greblin’s Focus Cap is really straightforward．You just wear it like a regular cap’ with the sides of the visor retracted，and just collapse the sides whenever you need to focus on what’s ahead of you．Whether you’re trying to focus on a task in an open work office．Trying to study at university，or practicing yoga in a park and trying to ignore stares from strangers，the Focus Cap can help．
To be honest，this whole project sounds like a joke，but the Focus Cap does have its own website where people interested in this unusual accessory can actually sign up for updates on when it will go on sale．Greblin claims it will cost 30 euros($37)plus shipping．
32. Which of the following can be the best title for the text
A. When to use the Focus Cap
B. How to operate the Focus Cap
C. The Focus Cap—an ordinary accessory
D. The Focus Cap—a visual-cancelling accessory
33. Why did Greblin create the Focus Cap
A. To help people focus． B. To develop intelligence．
C. To make people comfortable． D. To release creative potential．
34. What do we know about the Focus Cap
A. It’s expensive． B. It’s simple． C. It’s delicate． D. It’s complex．
35. From the text we can infer that ________．
A. The Focus Cap simply blocks unwanted sounds
B. The Focus Cap can only be used in the office
C. Greblin is confident about the future of his product
D. The Focus Cap has been on sale in quantity
【答案】32. D 33. A 34. B 35. C
【解析】本文是一篇说明文。本文主要介绍了The Focus Cap——一款消除视觉污染的帽子。
32. 主旨大意题。由最后一段To be honest，this whole project sounds like a joke，but the Focus Cap does have its own website where people interested in this unusual accessory can actually sign up for updates on when it will go on sale.可知，这篇文章主要介绍了The Focus Cap——一款消除视觉污染的帽子，选D。
33. 细节理解题。由第二段With so many people around and so much going on，some of us can easily get disturbed by this information overload and lose focus in what’s really important．That’s where the Focus Cap comes into play．可知，Greblin发明这款帽子是为了帮助人们集中精力，选A。
34. 细节理解题。由倒数第三段a simple cap with a retractable visor(可伸缩的帽沿)可知，这款帽子很简单，选B。
35. 推理判断题。由最后一段To be honest，this whole project sounds like a joke，but the Focus Cap does have its own website where people interested in this unusual accessory can actually sign up for updates on when it will go on sale．Greblin claims it will cost 30 euros($37)plus shipping．可推知，Greblin对他的这款产品的未来很有信心，选C。

英语单词记忆技巧
好多同学临近高考了英语还是很差，就非常的焦虑，现在和大家分享几个我自己的记忆方法吧！
1. 创造联系
将单词与其他事物联系起来，可以帮助您更容易地记住它们。例如，将“apple”（苹果）与您最喜欢的苹果派联系起来，并想象自己在享用这个美味的派时记住了这个单词。
2. 使用联想法
使用联想法也是一个很好的方法。例如，将“important”（重要）与“importance”（重要性）联系起来，并尝试将它们放入一个句子中使用。
3. 分类记忆法
将单词按照主题分类，比如动物、食物、交通工具等等，然后在每个分类下进行记忆。这样不仅可以帮助你更好地理解单词之间的联系，还能够提高你的主题词汇量。
4. 图像联想法
将每个单词与一个形象生动的图像联系起来。例如，将“apple”（苹果）与一个红色苹果图像联系起来。这种方法可以帮助你更好地记住单词，并且在需要用到这个单词时可以很容易地想起来。

As self — driving cars come closer to being common on American roads, much of the rhetoric (说辞) promoting them has to do with safety. About 40,000 people die on U. S. roads every year, and driver errors are linked to more than 90 percent of crashes. But many of the biggest advocates of autonomous vehicles aren’t car companies looking to improve the safety of their existing products. Huge backing for self - driving technologies is coming from Silicon Valley giants like Google and Apple.
Those of us who have studied the relationship between technology and society tend to look more carefully at the motivations behind any technological push. In this case, it’s clear that in addition to addressing safety concerns, Silicon Valley firms have a strong incentive (动机) to create a new venue for increasing the use of their digital devices. Every minute people spend on their mobile phones provides data - and often money - to tech companies.
At present, digital devices and driving are in conflict: There are serious, often fatal, consequences when drivers use smartphones to talk or to text. Regulators and safety advocates look to resolve dial conflict by banning phone use while driving - as has happened in virtually every state. But the tech companies are taking a different approach. The obvious answer for Silicon Valley is creating an antomobile in which continuous cellphone use no longer poses a threat to anyone.
In recent years, the amount of time adults spend on their mobile devices has grown rapidly. At the moment, it’s around four hours a day for the average adult in the U. S. However, that rapid growth is likely to slow down as people run out of time that ’ s available for them to use their devices. Unless, of course, there’s a new block of time that suddenly opens up. The average American now spends about 48 minutes in a car every day, a sizable opportunity for increased cellphone use.
So as the public conversation around autonomous cars highlights the safety advantages, don’t forget the tech industry ’ s powerful desire for more profits, which goes well beyond simply saving us from ourselves.
12. Who are responsible for most traffic accidents in America
A. Car companies. B. Tech companies.
C. Drivers. D. Self - driving cars.
13. What is Silicon Valley’s motive for promoting self - driving technologies
A. To make more money. B. To reduce traffic accidents.
C. To limit the use of digital devices. D. To support car companies.
14. What is the present - day solution to the conflict between digital devices and driving
A. Teaching people traffic rules. B. Improving self-driving technologies.
C. Fixing digital devices in cars. D. Banning phone use while driving.
15. What does the underlined phrase “a new block of time” possibly refer to
A. The working time. B. People’s spare time.
C. The time spent in the car. D. The time spent on mobile devices.
【答案】12. C 13. A 14. D 15. C
【解析】这篇文章主要对未来无人驾驶汽车的详细情况进行了介绍。
12. 细节理解题。由About 40,000 people die on U. S. roads every year, and driver errors are linked to more than 90 percent of crashes.可知在美国，司机是造成大多数车祸的原因，故选C。
14. 细节理解题。由Regulators and safety advocates look to resolve dial conflict by banning phone use while driving - as has happened in virtually every state.可知现在处理电子设备和驾驶的冲突之间的方法是开车时，禁止使用手机，选D。
15. 词义猜测题。由The average American now spends about 48 minutes in a car every day, a sizable opportunity for increased cellphone use.可知“a new block of time”指的是花费在汽车上的时间，选C。

必备单词（三）
知识梳理
01
高中英语单词记忆方法有抓住最佳记忆时间、找一个安静的环境记单词、用谐音记忆法记忆、在英语课堂尽量使用英语、合理开展强化练习。可以把单词的原文和汉语解释分别写在卡片的正反面，用橡皮筋扎住卡片的一头，经常翻阅背诵。要不断将已记住的单词挑出来，补充新单词，这样可以分批分类，区别对待，提高识记效率，便于随身携带，可利用零碎时间背记。
1、抓住最佳记忆时间
单词记忆效率的提高不仅取决于科学而有效记忆单词的方法，还取决于一天中记忆单词的时间。大量实验结果表明：上午8～10点钟和晚上8～10点钟是记忆单词的时间。
2、找一个安静的环境记单词
如果在一个室内狭窄而又十分嘈杂的环境中记单词，那些来自外界的噪声干扰会给大脑的正常记忆活动造成紊乱。相反，如果在景色宜人、空气清新的自然环境中记忆单词，人的大脑当然是处于一种清醒冷静的状态中，记忆单词的效果自然好于前一种情况。
3、用谐音记忆法记忆
尽管有些语言学家认为，用这种谐音记忆法记忆单词不科学，对学习者正确掌握发音不利，但学习外语的实践证明。在初学外语时，尚未掌握外语的构词特点和记词规律的初学者来说，采用谐音法记单词确实能有效地记住一部分难记的单词。
4、在英语课堂尽量使用英语
一般的英语老师在英语课堂上都是尽可能地利用英语来组织教学，无论老师说多说少，同学们都可以把这当成练习听力的好机会。在听得不大明白的情况下，要仔细听上下文，从老师前后的语言中来猜测、判断语意，或是根据老师的手势、眼神、动作等来分析，千万不要因为听不大懂而放弃。如果能利用好老师的课堂上的语言，对你的听力会有不少的帮助。
5、合理开展强化练习
在泛听的基础上，必须安排一定的时间进行专项、综合和强化性听力训练。选择难易适度的材料，先易后难，先慢后快地进行。
通过发音背单词
掌握单词拼写与发音之间的规律，发好每一个音标，读准每一个单词；还可以把包含同一元音的单词归为一类(如mistake，change，pain，gain，amazing…)集中操练，读起来朗朗上口，特别过瘾！通过发音背单词不但很快就能记住单词，更能练出地道发音！
跟着录音背单词
导致中国人背单词失败的最根本原因就是：发音不过关，单词读不准。所以一定要跟着标准的录音背单词。把音量开到最大，反复听录音并跟着大声朗读单词。这时候你的眼睛、耳朵、嘴巴全部用起来了，不断刺激大脑，印象也特别深刻！
三最法背单词
“默默无闻”地背单词效果极其低下！一定要用“三最法”狂读狂背每个单词。背单词的时候，一定要做到最大声、最清晰、最快速。当你用“三最法”操练单词时，你的注意力会高度集中，记忆的效率会大大提高，你不仅记住了单词，还锻造了国际口腔肌肉
单词家族背单词
英语中有很多单词都有整个家族，名词、动词、形容词、副词，加上不同的前缀、后缀就有不同的词性变化、意思变化。要想彻底掌握一个单词，我们要做的就是：整个家族一锅端！家族内所有的单词全部消灭！通过单词家族可以大大提升背单词的效率。

Robotic surgery is one thing, but sending a robot inside the body to carry out an operation quite another, which has long been a goal of some researchers to produce tiny robotic devices being capable of traveling through the body to deliver drugs or to make repairs without the need for a single cut, the possibility of which has just got a bit closer.
However, unlike the plot of one film—which featured a microscopic crew and submarine traveling through a scientists bloodstream — this device could not be inserted into blood vessels (管) because it is too big. While other types of miniature swallowable robots have been developed in the past, their role has mostly been limited to capturing images inside the body. In a presentation this week to the International Conference, Daniela Rus and Shuhei Miyashita of the Massachusetts Institute of Technology described a robot they have developed that can be swallowed and used to collect dangerous objects accidentally taken in.
To test their latest version, Dr Rus and Dr Miyashita designed a robot as a battery hunter, which might seem to he an odd task, but more than 3,500 people in America alone, most of them children, swallow the tiny button cells used in small electronic devices by accident every year. To start with, the researchers created an artificial esophagus (食道) and stomach made out of silicone (硅胶). It was closely modeled on that found in a pig and filled with medical liquid; the robot itself is made from several layers of different materials, including pig intestine (肠), and contains a little magnet. This is folded up and encased in a 10mm×27mm capsule of ice. Once this reaches the stomach the ice melts and the robot unfolds which is moved and guided with the use of a magnetic field outside the body. In their tests, the robot was able to touch a button battery and draw it with its own magnet, and during dragging it along, the robot could then be directed towards the intestines where it would eventually be gotten rid of through the anus(肛门). After it, the researchers sent in another robot loaded with medication to deliver it to the site of the battery bum to speed up healing.
The artificial stomach being transparent on one side, the researchers were able to see the batteries and visually control the robots. If not, that will require help with the help from imaging system, which will be a bit more of a challenge, but Dr Rus and Dr Miyashita are determined to succeed.
8. According to the passage, the robot operation will probably be able to ________.
A. travel through a scientist’s bloodstream
B. photograph the body to convey to the doctor
C. enter the body to deliver drugs or make repairs
D. operate on a person outside the body completely
9. We learn from Paragraph 3 that ________.
A. the researchers did the experiment on a chosen animal
B. one robot took necessary drugs besides a little magnet
C. digesting the swallowed batteries is difficult for children
D. the actual size of the robot may he larger than the capsule of ice
10. What may the experiment mean to the medical world
A. The surgeries will cost patients much money.
B. Patients will suffer less for sonic surgeries.
C. Fewer children will swallow the button cells.
D. A robot will be invented travelling blood vessels.
11. Which can be the most suitable title for the passage
A. An Experiment on Robot
B. Tiny Robot, Great Researchers
C. The Exploration of Robot Technology
D. The Fantastic Robotic Voyage
8. Ｃ
推理判断题。根据第二段第句“unlike the plot of one film—which featured a microscopic crew and submarine traveling through a scientists bloodstream — this device could not be inserted into blood vessels (管) because it is too big.”根据内容可知，电影里的情节，特点把一组显微镜进入科学家的血液流动，因为太大而不能进入血管，可知A是错误的。根据“While other types of miniature swallowable robots have been developed in the past, their role has mostly been limited to capturing images inside the body.”可知B是错误的。D项文中没有提及。文章提到研究学者长久以来希望可以研制出能够灵活穿梭于人体的小型机器人设备，用以输送药物，或无须动刀就能完成治疗。此项技术研发明已小有突破。Rus和Miyashita博士设计了一款用于取回人体内电池的机器人。通过被折叠并包裹于胶囊内，被吞下进入人体，在体外磁场的操控下工作，引导电池通过肛门排出。再由另一个装有药物的机器人送到电池灼烧处，加快伤口愈合。。最后一段说这将是一个更大的挑战，但Rus博士和宫崎骏博士志在必得。由此可知机器人手术进入人体运送药物或修复是有可能的。即C项是正确的。
9. Ｄ
【解题剖析】此题属于推理判断题中的（4）根据事实细节，推断合理信息。答案需要从文章的his is folded up and encased in a 10mm×27mm capsule of ice. Once this reaches the stomach the ice melts and the robot unfolds which is moved and guided with the use of a magnetic field outside the body.进行推断。
【答案定位】根据第三段中的“This is folded up and encased in a 10mm×27mm capsule of ice. Once this reaches the stomach the ice melts and the robot unfolds which is moved and guided with the use of a magnetic field outside the body.” 这是被折叠和包裹在一个10mm×27毫米冰胶囊里。一旦到达胃部，冰胶囊融化，机器人打开，利用体外的磁场移动和引导操控机器人。因为它进入人体时是被折叠的，到了胃部冰融化后机器人打开，由此可判断机器人的实际大小比冰胶囊大。。
10. Ｂ
推理判断题。本实验是测试最新版本的机器人用于取回人体内的异常物。在第三段中提到在测试中机器人可通过被折叠在冰胶囊里被吞下进入人体，通过体外操控把异物拖到肠道通过肛门排出，再由另一个装有药物的机器人送到电池灼烧处，加快伤口愈合。如果没有，这将需要帮助的成像系统的帮助，这将是一个更大的挑战。由此可判断这个实验会让病人减少超声手术之痛。分析选项可知B项正确。
11. Ｄ
主旨大意题。机器人手术是一回事，但是要将机器人送入人体做一台手术，输送药物，或无须动刀就能完成治疗。此项技术研发现已小有突破。Rus和Miyashita博士设计了一款用于取回人体内电池的机器人。通过机器人被折叠并包裹于胶囊内，被吞下进入人体，在体外磁场的操控下工作，引导电池通过肛门排出。再由另一个装有药物的机器人送到电池灼烧处，加快伤口愈合。由此可知这是一件多少令人不可思议的人体旅行。分析选项可知D项作为题目最好。故选D项。
