上海市高考英语专题冲刺-十一选十 解题策略与练习巩固

上上上2020届上上上上上上上上上四上—— 十一选十(小猫钓鱼)一、题型特征及考点十一选十只考察四类实词,即:名词、动词、形容词、副词。
做题看所给词汇时,我们要么在内心谨记题目中所给的十一个词中每个词的多种词性和意思,只可惜有时候你可能会很难做到这一点,所以还是老老实实花个一两分钟左右仔细看清每一个单词,记住都有谁,并在每个单词旁边按注其含有的词性及诸如现在分词、过去分词、动名词以及各种分词式的形容词这类非词性方面的语法层次的特征(只出现在分词中)。
这样接下来在面对某一个空格时,只要根据上下文的语法结构或逻辑关系不再是从10个词中去选1个答案了,可以是4选1甚至2选1,从而缩小了选择的范围,提高做题的准确率。
1、选词填空的特点1) 文章长度一般350字左右;2) 第一句是主题句,一般均不设空(各种题型第一句话几乎均不设空);3) 每隔15-30个词有一个空,共10空;4) 方框中词汇兼顾一词多性、一词多义、派生【即前缀、后缀】、合成词、引申义等方面综合考察;5) 文章略低于完形填空、阅读理解C篇的难度。
2、选词填空的考点1)词汇方面:考察4类实词,即:名词、动词、形容词、副词;2) 语法方面:考察词性之间关系和句子结构分析的能力;3) 逻辑方面:考察上下文逻辑分析及语篇分析的能力。
3、需要注意的五个要点:(1) 词性判断(2) 常用搭配(3) 内在逻辑(4) 感情色彩(5) 语法常识二、解题步骤第一步:通读全文通读全文是用较快速度,一行一行地读,目的是把握至少90% 的内容。
选词填空的选项词义互不关联,词性也不同,而且还有干扰项,一定要先了解文章大意,带着文章脉络去找选项。
务必先沉着地把文章读一遍,尤其注意横线前后的位置,为寻找正确选项打下铺垫。
提醒:通读就是根据首段原则以及首末句原则,迅速抓出文章的主题。
判定文章主题对于篇章的整体把握具有很大的积极意义。
第二步:整理选项classify the options我们应该根据词性把选项中的每个单词进行分类归纳标,标出它们的词性。

Australian businessmen Kevin Garcia and Jon Tse spent a year researching a possible __31__ that could serve as a possible raw material for makingpaper. Then Garcia read about a Taiwanese company making commercial paper out of stone and a(n) __32__ struck.A year later, in July 2017, they launched Karst Stone Paper.

Their source is stone waste __33__ from construction sites and other industrial waste dumps.“If you look at the whole process of how paper is traditionally made, it __34__ chopping trees,adding chemicals, using lots of water and then __35__, drying and flattening it into sheets of paper, “ said Garcia. "It contributes to high carbon emissand deforestation. ”In 2019, Garcia estimates Karst paper production has helped save 540 large timber trees.(成材木)from being deforested, 83,100 liters (21,953 gallons) of water from being used and 25,500 kilograms (56,218 pounds) of carbon dioxide from being __36__.“We collect disposed limestoneH 灰石)from wherever we can find it, wash it, and grind it into fine powder, “ he said.

Stephen Hawking was definitely one of them.Hawking was a theoretical physicist whose early work on black holes __31__ how scientists think about the nature of the universe. Lawrence Krauss, a theoretical physicist from Arizona State University and a friend and colleague of Hawking's, says that at a young age. Hawking __32__ something “trulyremarkable "Kr auss says before Hawking , physicists thought that the large gravity of a black hole __33__ everything in and nothing could escape. But by combining quantum mechanics 量子力学)and the theory of relativity, Hawking showed something and changed everything about the way we think about gravity. Krauss says Hawking pointed outa(n) __34__ problem in the way physicists understand our world - a problem that Krauss says has yet to be resolved.But his fame wasn ' t just a(n) __35__ of his research. Hawking, who had a rare disease that made it impossible for him to move or speak, was also a popular public 36 and best-selling author. When he came to scientific conferencesthe audience focused their attention on him. And it wasn ' t just the scientists but the general public as well who showed great __37__ for him. His popular book about his work, A Brief History of Time, was a best-seller. But he agreed that that book was probably the least-read, most-bought book ever. This showed Hawking's sense of humor.That senseof humor, along with his fame, __38__ Hawking to appear on TheSimpsons several times as well as on a number of other popular shows.Toward the end of his life, Hawking s disease left hi imlOlmost .It look anenormous __39__ for Hawking to communicate, using the tiny movements he could make to control a computer. It ' s tempting to say that Hawking achieved his fame inspite of his __40__ challenges.虹口Cigarettes aren t good for us. But how exactly do cigarettes harm us? Letsat what happens as their ingredients make their way through our bodies, and how we benefit(31)when we finally give up smoking.Inside the airways and lungs, smoke increases the (32)of infections as well as long - lasting diseases.It does this by damaging the tiny hair - like tissues which keep the airways clean. That ' s one of the reasons smoking can lead to oxygen loss and (33)of breath.Within about 10 seconds, the bloodstream carries a stimulant called nicotine to the brain, creating the (34)sensations which make smoking highly addictive. Nicotine and other chemicals from the cigarette, at the same time, cause tightness of blood tubes, restricting blood flow. These effects on blood tubes lead to (35) of blood tube walls, increasing the possibility of heart attacks and strokes.Many of the chemicals inside cigarettes can activate dangerous (36)in the body' D NA that make cancers form. In fact, about one of every three cancer deaths in the United States is caused by smoking. And it ' not just lung cancer. Smoking can cause cancer in multiple tissues and organs, as well as damaged eyesight and (37)bones. It makes it harder for women to get pregnant. And in men, it can cause long-term damages of body functions.But for those who quit smoking, there s a huge positive upside with almost (38) and long-lasting physical benefits. A day after ceasing, heart attack risk begins to decreaseas blood pressure and heart rates (39). Lungs become healthier after about one month, with less coughing. After ten years, the chances ofdeveloping fatal lung cancer go down by 50%, probably because the body s ability to repair DNA is once again restored.There' no point pretending this is all easy to achieve. Quitting can lead to anxiety and depression. But fortunately, such effects are usually (40). Advice and support groups and moderate intensity exercise also help smokers stay cigarette - free. That' good news, since quitting puts you and your body on the path back to health.徐汇In the past few years, scientists have found microplastics in our soil, tap water, bottled water, beer and even in the air we breatheAnd there ' s growing concern aboutthe 31 health risks they pose to humans.The new analysis in the UK have discovered microplastics widely ________ 32across all 10 lakes and rivers sampled. More than 1,000 small pieces of plastic per litre were found in the River Tame, which was 33 last year as the most polluted place tested worldwide. Even in relatively remote places such as the Falls of Dochart and Loch Lomond in Scotland, two or three pieces per litre were found.Microplastics are not a 34 kind of plastic, but rather any type of small pieces of plastic that is less than 5 mm in length according to the U.S. National Oceanic and Atmospheric Administration. They may 35 from a variety of sources, including cosmetics, clothing, and industrial processes.Humans are known to 36 the tiny plastic particles through food and water, but the possible health effects on people and ecosystems have yet to be determined. One study, in Singapore, has found that microplastics can 37 harmful microbes (微生物).Research by the National University of Singapore found more than 400 types of bacteria on 275 pieces of microplastic collected from local beaches.They included insects that cause gastroenteritis!(胃炎)and wound 38 in humans.“Microplasticsare being found 39 everywhere but we do not know the harm they could be doing, " said Christian Dunn at Bangers UniWales, who led the work. “It nos use looking back in 20 years time and saying: ' Ifonly we' d realized just how bad it was. ' We need to be monitoring our waters now and we need to think, as a country and a world, how we can be reducing our 40 on plastic. ”松江31-40 DGJHI KCFEA 崇明31-40 DFAJC H1BGE 徐汇31-40GAKHI DECBF黄浦31- 40 BEGKA JHCFD虹口31-40 GCIAE BKFJH。

Complete the following passage by using the words in the box. Each word can only be used once. Note that there is one word more than you need.Internet use appears to cause a decline in psychological well-being, according to research at Carnegie Mellon University. Even people who spent just a few hour’s a week on the Internet experienced more ___41_ and loneliness than those who __42__ on less frequently, the two-year study showed. And it wasn’t that people who were already feeling bad spent more time on the Internet, but that using the Net ___43___ appeared to cause the bad feelings.Researchers are puzzling over the results, which were completely __44__ to their expectations. They expected that the Net would prove __45__ healthier than television, since the Net allows users to choose their information and to communicate with others.The fact that Internet use reduces time __46__ for family and friends may account for the drop in well-being, researchers hypothesized. Faceless, bodiless “__47__” communication may be less psychologically satisfying than actual conversation, and the relationships formed through it may be shallower. Another possibility is that __48__ to the wider world via the Net makes users less satisfied with their lives.“But it’s important to remember this is not about the technology; it’s about how it’s used,” says psychologist Chirstine Riley of Intel, one of the study’s __49__. “ It really points to the need for considering social factors in terms of how you __50__ applications and services for technology.”Recently, British universtiy researchers said that a computer programme can help Asian students to deal with ___41_ English accents which are difficult to understand. This is good news for students who get ___42___ by different English accents.Computer scientists at Nottingham University said that some Asian students in Britian find it difficult to understand the range of different English accents. Among native English speakers, many different accents ___43___. Some accents are easily __44____ by certain characteristics. But more variations can be difficult to understand.Difficulties can be eperiencec in the process of differentiating sounds at the end of spoken English words, like rope versus robe, and at the start, like tin versus thin. This can make __45____ speech difficult to follow, as misunderstanding a single word can potentially change the whole ___46___ of a sentence. It would be useful to have something that would make it easier for foreign students to understand different English accents.The researchers’ Spoken English Discrimination (SED) training programme can train Chinese speakers in how to ___47___ differences in speech sounds in difficult conditions, such as accented speech or in situations in which there are a number of sounds in the background, a university release reported.“Our findings have shown that SED training programme really does have a significant __48____ on enabling Asian students to differentiate between sounds,”reseacher, Nicola Pitchford said. “There is a __49____ potential for SED. There has already been interest in theprogramme, from government organizations, through to a major Chinese mobile phone company who os interested in developing it into an educational phone ___50___.”twentieth anniversary of Earth Day. The purpose of the holiday, which we celebrate every year on that __41____, is to help people learn how to protect the planet Earth. People around the world celebrate Earth Day because they worry about the planet. Many __42____ of animal life are desappearing from the earth. Carelessness and accidents in many countires have cauaed problems that are harmful to the environment. Air and water pollution, oil spills, and poisonous waste are some of the __43____ problems.In fact, protecting the earth is truly a worldwide __44____. An accident in a nuclear power plant in one country can create a radioactive cloud that goes ___45___ around the world. Factory smoke in onecountry can cause acid rain in another. One country’s oil tanker can __46____ oil that floats to the shores of another. It is eas to see how our protecting the environment has become an international issue.So, in order to begin the difficult job of saving the earth, people around the world did special things on Earth Day, 1990. In Japan, divers ___47___ garbage from the sea. In Nepal, climbers picked up trash on Mount Everst. Students marched in support of Earth Day in Hong Kong, and people grew ___48___ plants in the Phillippines. In the United States, children planted trees. Native Americans told stories about the creation of the earth, artists ___49___ pictures on walls next to highways, and musicians gave __50____ to support the work of environmental groups. Almost everyone everywhere stopped for a moment to think about how we can protect the earth.many ways. Many in-home jobs that used to be done ______ by women-ranging from family shopping to preparing meals to doing ______ work-still need to be done by someone. Husbands and children now do some of these jobs, a ______ that hs changed the target market for many products. Or a working woman may face a crushing “poverty of time” and look for help elsewhere, creating opportunities for producers of frozen meals, child-care ceters, dry cleaners, financial services, and the like.Although there is still a big wage ______ between men and women, the income working women ______ gives them new independence and buying power. For example, women now ______ aobut half of all cars. Not long ago, many car dealers ______ women shoopers by ignoring them or suggesting that they come back with their husbands. Now car companies have realized that women are ______ customers. It’s interesting that some leading Japanese car dealers were the first to ______ pay attention to women customers. In Japan, fewer women have jobs or buy cars –the Japanese society is still very much male-oriented. Perhaps it was the ______ contrast with Japanese society that prompted American firms to pay more attention to womenbuyers.Reading is one of the important skills in English learning. Its purpose is to enlarge their vocabulary and familiarize themselves with background __41____ about English and to cultivate students’ careful observation and their logic thinking. What is more, it is to __42____ students’comprehension. I have tried to train my students in the following ways: skimming and scanning, author’s viewpoint, __43____ of the passage, structure of paragraphs, students’anticipation, punctuation and summarizing. Before starting to read a passage in detail, I __44____ ask the students to take a moment to preview the passage. Read quickly, without pausting to ___45___ the details. This is called skim reading. The students ask them to have these in mind: for which the passage was __46____, what type of passage it is, what the purpose and attitude of the __47____ is and what the style of the article is.After having skimmed the passage, the students can study the passage in more detail, reading more slowly and ___48___ and looking for specific information that the questions are concerned with. This is called scanning. When students do the scanning, I ask them to read without any sound, to notice only the key words and not to pay too much __49____ to the new words but to pay the sense group and the main meaning of the sentence. Especially pay attention to the first __50____ and the last sentence of the paragraph.It can be risky to generalize about the literature of any culture or group. For amlost any statement that is made, exceptions can be found. Nevertheless, literary __41____ is all about generalizations. Here are some that are made about Asian-American literature.All Asian-American writers can be placed into one of two groups, those who emigrated to the United States and those who were born here but of immigrant families. They represent a ___42___ and diverse range of countries, from Japan and the Philippines in the east to Iran and Turkey in the west.Some of the topics that first-generation writers deal with are __43____ to all immigrant people: the difficult ___44___ to a new land, a loneliness for home, and an uncertainty about the new culture. So you might find tales of a Vietnamese immigrant’s horrific departure after the ___45___ of Saigon or the struggle against prejudice (偏见) __46____ in a book like Carlos Bulosan’s autobiographical America Is in the Heart.Family values can be a source of much rich literature. All Asian-American groups carried __48___ customs and practices with them, and sometimes these were looked on with ___47___ by their new countrymen. They certainly were a cause of misunderstanding and sometimes contention between immigrants and their American-born children. Books like Jade Snow Wong’s Fifth Chinese Daughter make this clear.More, perhaps, than some other groups, Asian Americans have been __49____ with language: how it sets them apart from others, the importance of mastering American English. In as essaycalled “Mother Tongue”, for example, writer Amy Tan discusses how her mother’s less-than-perfect English __50____ her own life and her views of herself.after local users complained about them not __41____ the tradition of standing in line.Southern Vectis Bus Company, which operates buses on the Isle of Wight, off England’s south ___42___, said it was to contact local language schools following several __43____ about the behavior of young students over the summer vacation.“On the Isle of Wight we get lots of foreign language students __44____ with families,” said operations manager March Morgan Huws.“In their ___45___, they do not queue for buses where they live and there is a scrum (相互拥挤) every time a bus turns up, while in British culture there is a nice __46____ queue.”“We have had quite a few complaints from __47____ who queue up in an orderly fashion then all those foreign students push past them.”“We will work with the language schools to provide some __48____ on the etiquette of queuing. We won’t be arching the students up and down showing them how to queue, we will just leave it up to the group leader to pass on the information.”Orderly queuing –as seen during the recent Northern Rock banking crisis –is seen as a ___49___ British tradition. One social anthropologist believes Brotons are even ___50___ of forming one-person queue at bus stop.Unfortunately, a controversial political democracy is little that can be done in a cowboy outdated. Inefficient and bankrupt health care focused, comprehensive manner likely to make a real difference must be __41____. There are simply too many moving parts and special interests. However, a gradual change is under way. Insurance __42____ with health care organizations accountable and the integrated system is clinically effective. So hospitals and health centers will ensure ___43___ compensation. Expect to develop these new systems in the private sector as well.Pressures from the government to the implementation of the electronic medical records are __44____ essential for the development of data-driven systems, not only for financial __45____, but also for the quality of performance and results and receive data accounting for performance in the management of patient care. With the coming of more reliable and more __46____ to evidence-based medicine, what ___47___ and what does not, and we will go to largely ___48___ access to an experience in health care. Results are examined, __49____ and treated. The development is based on the system of accountability in the delivery of the most effective care and the most reasonable price. This is only possible id hospitals and health care providers concentrate on the supplying of health services. Look at the rise and progress of compensation of healthcare __50____ fully integrated into the world and see the decay and death for the costs of medical services.when you are going to the cleaners, your credit card when you are shopping…Such absent-mindedness may be __41__ to you; now British and German scientists are developing memory glasses that record everything the __42__ sees.The glasses can play back memories later to help the wearer remember things they have forgotten such as where they left their keys. And the glasses also __43_ the user to “label” items so that information can be used later on. The wearer could walk around an office or a factory identifying certain __44__ by pointing at them. Objects indicated are then given a __45__ label on a screen inside the glasses that the user then fills in.It could be used in ___46_ plants by mechanics looking to identify machine parts or by electricians wiring a __47_ device.A spokesman for the project said: “ A car mechanic for __48__ could find at a glance where a part on a certain car model is so that it can be identified and repaired. For the motorist the system could ___49_ accident black spots or dangers on the road.”In other cases the glasses could be worn by people going on a guided tour, __50__ points of interest or by people looking at panorams where all the sites could be identified.。
