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。

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.

The notebooks cost $10 to $25. Karst ' s products are mainly sold through the company ' s website, but are also stocked in 100stores, __39__ throughout Australia, the United States and the United Kingdom.“ Over 70% of theustomers are US -based, " he said.The hope to have the notebooks in 1,000 stores by the end of the year.

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。

上海高考英语词汇小猫钓鱼解析

上海高考英语词汇小猫钓鱼解析

小猫钓鱼从2008年起,词汇的考查放在了语篇中,着重强调语法和词汇知识在特定情景中的应用(通称小猫钓鱼)。

试卷10道词汇题以10选9的方式分别考察了动词,形容词,名词,副词,还包括现在分词和过去分词的形式。

2014年语法选择取消之后,词汇题增加了一个空,改成了11选10。

通常做题时间不超过12分钟,10分钟之内完成为佳。

1、选词填空的特点1) 文章不会太长(350词左右);一般来说第一句是文章主题句并且不设空;一般每隔10-30个词会有一个空;空与空之间有完整意群。

文章中会挖出十个空,但是给出了十一个单词,让学生选择填空使文章完整,这就是新题型轮廓。

2) 方框中词汇难度不高,文章难度要略低于阅读理解难度。

实际上是将词汇的使用和完形阅读紧密结合的一道题目。

【事实上很多同学词汇关过不了,11个词汇有一半以上不认识,这样肯定无法选出正确答案。

但是如果仅有一两个不认识,掌握了一定的技巧,完全可以做到全对。

】2、选词填空的考点1) 词汇方面以实词为主也就是指名词、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能力。

3) 逻辑方面考察上下文联系3、解题点拨:1) 最关键的是要改变孤立的记忆单词的不良学法,做到词不离句,句不离篇,做到词汇的情景使用。

页脚内容12) 不要孤立的看文章,一定注意句子的上下文衔接和本句的语法结构,因为选一个就少一个,一发而动全身。

3) 要专门记忆些高难词汇,也就是拼写很长词汇,比如:prohibited, withdraw, delicately之类。

4) 要想到这些词汇是不是有些固定用法。

★第一步:略读全文,定中心考生拿到题目以后,由于考查考生对篇章的理解,应该略读整篇文章,确定文章的中心或主要说明的问题。

文章大概在220词--250词左右,用1分钟左右的时间略读即可。

要抓住文章首句,迅速找到文章的主题词或主题。

和完型填空一样,一般文章第一句不设空格,以便让考生知道本文的相关主题词或主题。

2024年上海市高考语文备考之现代文阅读练习题

艰难时世(美)罗恩·拉什①“矮脚鸡下面一只蛋都没有,”埃德娜说,“都连续四天这样了。

”②“兴许是那只老公鸡重新黏上她了。

”雅各布说道。

③“你就继续开玩笑吧,”埃德娜回答说,“可咱们靠卖鸡蛋换得一点儿现金很紧要。

也许关系到你有没有五分钱来浪费在一份报纸上。

”④“可有许多人比咱们还穷呐,”雅各布说。

⑤“咱们仍旧可能会落得像哈特利一样。

”埃德娜回嘴道。

她的视线越过雅各布,落到道路尽头,也就是伐木厂运送圆木留下的土路开始的地方。

“大概是他养的癞皮狗偷走了咱家的鸡蛋。

”⑥“你也不能肯定。

我仍旧觉得,若是狗偷吃鸡蛋的话,会在鸡窝里的稻草上留下些蛋液。

我从没见过哪条狗吃鸡蛋不滴下蛋液的。

我会去察看一下。

”⑦雅各布穿过庭院,进了混凝土建造的鸡舍里。

雅各布拿起矮脚鸡,把它放到地上。

鸡窝里的稻草上,见不到蛋壳碎片,也不见蛋白蛋黄的残液。

⑧雅各布心里明白,这可能是一个长两条腿的窃贼干的,可尽管时世艰难,他也从没听说山坳里的哪个居民会偷东西,尤其是哈特利,山坳里最穷的那个。

此外,鸡舍里放着两打多鸡蛋,谁会仅仅偷去两三个呢?⑨雅各布走出鸡舍的时候,见到哈特利一家从土路上走下来。

他们全家人每周会去布恩两次,每次得走上两英里路,就连他家的小孩也要去,每个人都拿着重重的银禾叶。

哈特利一家瘦骨嶙峋的骨架上,挂着褴褛的衣衫,他们看起来就像是随身携带了全部家当、要转场到另一块麦地的稻草人。

他家的狗跟在后面,和它所追随的主人一样身形憔悴。

原本,只要锯木厂一直经营着,生计便不是大问题,可当锯木厂关门歇业后,哈特利家只能靠一头背部下陷的老迈奶牛来维持生计,除此之外,只剩下银禾叶了,用它可以在杂货店换得几毛钱的杂货。

雅各布从他买的星期日报纸上知道,到处都是经济大萧条。

有些人攀在火车的货车顶上,从一个城镇去往下一个城镇,祈求能得到一份工作。

⑩哈特利一家本来会这样不声不响地走过去,然而,埃德娜突然走到了门廊上。

⑪“你们家的狗,”她对哈特利说道,“是不是爱偷鸡蛋啊?”埃德娜也许并不想用责问的语气说话,但这番话听上去就是气势汹汹。

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.

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.

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.

People around the world celebrate Earth Day because they worry about the planet. Many __42____ of animal life are desappearing from the earth.

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.

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.

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.

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.
