高三(上)限时练四

热点04 语法填空【命题趋势】在一篇200左右词的短文中留出十个空白，所设空白分有词填空和无词填空二种。

有词填空题考查：时态、语态、形容词或副词的级、非谓语动词和简单构词法。

无词填空考查：代词、冠词、连词、介词和情态动词。

要求考生根据空白所在句的句式结构及句子间的逻辑关系，用适当的词或所给词的适当形式填写，以便使短文准确无误。

本题型主要考查考生在文章中正确使用英语语法知识的能力。

【满分技巧】答题原则：以句子为单位来考虑含有空白的句子。

答不出时，再考虑设空所在句与前句或后句的关系。

A. 有词填空题这类题在一个设空处可填一至三个词，其中考查最多、最难的是用动词的正确形式填空。

这包含对时态、语态、非谓语动词及构词法知识的考查。

首先要确定该空应该使用谓语动词(时态、语态、)还是用非谓语动词。

规律是：每个句子(从第一个词到句号或叹号算作一个句子)都遵循这个等式：谓语数-1=连词数。

其中一个破折号(若后面是句子)、分号、冒号算作一个连词；连接并列成分的连词，承接上文的连词，以及when、if、though与非谓语动词连用时的不计数。

在填含有已给动词的空白时，依据已知的谓语动词和连词的数量所构成的等式来判断。

若左边(前面)再加1等式才成立，需要填谓语动词；若相等，需要填非谓语动词(详见下列《技巧应用》)B. 无词填空题这类题一个空白只许填一个词，其中考查最多、最难的是填从属连词。

判断是否填连词的方法也是根据上述等式(遇到难句、长句、复杂句，才使用)来考虑：即, 若右边(后面)再加1等式才成立, 需要填连词。

考查代词、冠词、连词、介词、形容词或副词的级和情态动词的填空题相对较简单。

将在《技巧应用》或《限时检测》中详述。

【技巧应用】下面以《2019年高考英语卷二》为例来阐述《满分技巧》的实际应用：A. 原题A 90-year-old has been awarded "Woman Of The Year" for 61 (be) Britain's oldest full-time employee —still working 40 hours a week. Now Irene Astbury works from 9am to 5pm daily at the pet shop in Macclesfield, 62 she opened with her late husband Les. Her years of hard work have 63 (final) been acknowledged after a customer nominated (提名) her to be Cheshire's Woman Of The Year.Picking up her“Lifetime Achievement”award, proud Irene 64 (declare) she had no plans 65(retire) from her 36-year-old business. Irene said, "I don't see any reason to give up work. I love coming here and seeing my family and all the friends I 66 (make) over the years. I work not because I have to, 67 because I want to."Granddaughter Gayle Parks, 31 —who works alongside her in the family business —said it remained unknown as to who nominated Irene for the award. She said, "We don't have any idea who put grandma forward. When we got a call 68 (say) she was short-listed, we thought it was 69 joke. But then we got an official letter and we were blown away. We are so proud of her. It's 70 (wonder).”B. 应用【文章大意】本文为记叙文。

题组一 双基练1. [2021·福州高三期末]如图所示，一束光线从折射率为1.5的玻璃内射向空气，在界面上的入射角为45°，下面四个光路图中，正确的是 ( )解析：本题考查全反射条件．光从玻璃射向空气，是从光密介质射向光疏介质，由于玻璃的折射率n ＝1.5，因此发生全反射的临界角sin C ＝1n ＝23<22，所以C <45°，因此图中的光会发生全反射，A 项正确．答案：A2. [2022·福建高三仿真模拟]如图所示，有一束光投射到放在空气中的平行玻璃砖的表面Ⅰ上，下列说法中正确的是 ( )A. 假如在界面Ⅰ上入射角大于临界角，光将不会进入玻璃砖B. 光从界面Ⅱ射出时出射光线可能与最初的入射光线不平行C. 光进入界面Ⅰ后可能不从界面Ⅱ射出D. 不论光从什么角度入射，都能从界面Ⅱ射出解析：发生全反射的必要条件有两个，即光从光密介质射入光疏介质和入射角不小于临界角，本题中光从空气射入界面Ⅰ上时，光是从光疏介质射入光密介质，所以即使入射角大于临界角，光也不会发生全反射现象，光会进入玻璃砖，选项A 错误；由于光的上、下两个界面平行，光从界面Ⅱ射出时出射光线确定会与最初的入射光线平行，选项B 错误；光进入界面Ⅰ后，从玻璃射向界面Ⅱ时的入射角确定小于临界角，光确定会从界面Ⅱ射出，选项C 错误；不论光从什么角度入射，都能从界面Ⅱ射出，选项D 正确．答案：D3. 夜间行车光照在警示标志上后反射回来特殊醒目，主要是由于警示标志是由球形的反射物制成，如图，假设反射物为分布均匀的球形，其折射率为 3.某次灯光照射在该标志上后，经球形物一系列的折射和反射后，出射光线恰与入射光线平行，则第一次的入射角( )A. 30°B. 45°C. 60°D. 15°解析：设入射角为i ，折射角为θ，作出光路图，由于出射光线恰好和入射光线平行，所以i ＝2θ，依据折射定律sin i sin θ＝sin2θsin θ＝3，所以θ＝30°，i ＝2θ＝60°.答案：C4. [2022·江苏南京]如图甲所示，在安静的湖面下有一个点光源S ，它发出的是两种不同颜色的a 光和b光，在水面上形成了一个被照亮的圆形区域，该区域的中间为由ab 两种单色光构成的复色光的圆形区域，周边为环状区域，且为a 光的颜色(图乙为俯视图)．则以下说法中正确的是 ( )A. 水对a 光的折射率比b 光的大B. a 光在水中的传播速度比b 光的大C. a 光的频率比b 光的大D. 在同一装置的杨氏双缝干涉试验中，a 光的干涉条纹比b 光窄解析：依据“周边为环状区域，且为a 光的颜色”知，点光源射向水面的单色光b 在环形区域内边界处发生全反射，而单色光a 在外边界处发生全反射，即水对单色光b 的临界角C 较小，由sin C ＝1n 可确定水对单色光a 的折射率比b 光的小，A 项错误；由折射率公式n ＝cv 知，a 光在水中的传播速度比b 光的大，B 项正确；a 光的频率比b 光的小，C 项错误；a 光的波长比b 光的大，干涉条纹间距与波长成正比，所以在同一装置的杨氏双缝干涉试验中，a 光的干涉条纹比b 光的宽，D 项错误．答案：B5. 如图所示的长直光纤，柱芯为玻璃，外层以折射率较玻璃低的介质包覆．若光线自光纤左端进入，与中心轴的夹角为θ，则下列有关此光线传播方式的叙述正确的是( )A. 不论θ为何值，光线都不会发生全反射B. 不论θ为何值，光线都会发生全反射C. θ够小时，光线才会发生全反射D. θ够大时，光线才会发生全反射解析：发生全反射的条件之一是入射角i 要大于等于临界角C ，即光线传播到光纤侧面时的入射角i 应满。

D．To evaluate musicals.ⅡMost people find sugar hard to resist. Our big brains need lots of energy and sugary foods provide plenty of it. But when calories are too readily available, it is easy to overdo it.There has been no shortage of research on sugar substitutes that trigger a sweet sensation without the calories, but these alternatives also taste slightly bitter for many people. W hat’s more, evidence from animal and human studies has linked some to glucose intolerance and weight gain.One promising alternative is found in the fruit of Synsepalum dulcificum (奇妙果), a plant native to West Africa. These miracle berries don’t taste suga ry themselves, but if you try something sour afterward, it will taste miraculously sweet. In Benin, the fruit is eaten fresh and is mostly used as a sweetener to have with sour foods and drinks. The berry is appreciated by local consumers, especially the kids and people with diabetes who use it as a substitute for synthetic sugar.The chemical, a protein named miraculin, was identified in 1968 and a team in Japan discovered how it works in 2011. At neutral pH, miraculin is an antagonist to our sweet taste receptors, meaning it blocks the taste of sweetness. But in the presence of an acid, miraculin changes shape and is able to activate the receptors.Despite the miracle berry’s promise as a sugar substitute, it is only produced on a smallish scale and isn’t available worldwide. The berries don’t travel well and the plant is slow to grow and mature.To create an alternative source of miraculin, researchers in Japan have genetically engineeredtomatoes to produce the protein, while another team is working on increasing the production of miracle berries in West Africa. Earlier 202X, a team in China published the genome of Synsepalum dulcificum. A Spanish start-up plans to promote sustainable cultivation of the plant in Ghana and market the dried berries as a food supplement.；4．What is special about Synsepalum dulcificum as a sugar alternative?A．It contains many calories itself. B．It makes sour food taste sweet.C．It will gain weight and cause disease. D．It does good to kids and diabetic patients.；5．How do the miracle berries work on sour food?A．By changing the pH of a food. B．By increasing its sugar content.C．By producing shape-variable miraculin. D．By weakening the sweet taste receptors.；6．What does the underlined word “antagonist” probably mean in Paragraph 4?A．Enemy. B．Assistant. C．Factor. D．Receiver.；7．Why are the miracle berries hard to get?A．They are only locally available. B．They cannot be grown elsewhere.C．It is expensive to transport them. D．It takes long to harvest a small amount.二、七选五阅读How to make a successful apology. Have you done something that you feel bad about? Is there a person who you have treated badly?

材料一：中国人说中国话，用汉语写作，可是我们了解自己的语言吗如果不了解，如果我们超越汉语的表达界限说话，会出现怎样的情形呢长期以来，我们总是一厢情愿地设想，西方语言固有的成分，汉语中也一定或明或暗地隐藏着，最害怕被西方人说汉语是一种蒙昧的语言。

冯友兰先生的意见，就代表了这样的立场，他说中国哲学与西方哲学是古今之争。

换句话说，中国哲学之所以“落后于”时代，是因为汉语“落后”;但是，按照这样的逻辑推论，汉语永远不得不落后，除非汉语成为拼音文字。

与其说汉语与拼音文字之间，中国哲学与西方哲学之间，是人类古代语言与现代语言或原始思维与现代思维之争，不如说它们之间仅仅是一种空间上的并列关系，彼此相互外在，互不附属，一点儿也不像。

所谓“先进”与“落后”的断语之所以不中用，是因为这个标准来自西方。

举个例子来说，按照西方语言和语法标准分析汉语，往往就要说外行话，因为这个分析的工具不中用。

“中国言语的构造上主语(subject) 与谓语(predicate) 的分别极不分明，换言之，即可以说好像就没有这个分别。

这是中国言语构造上的最特别处，而其影响则甚大”(张东荪)。

既然汉语几乎就没有主语与谓语的分别，那么当我们硬说有这个分别时，就好像“使中国文法亦穿了一套西服”(张东荪)。

有怎样的害处呢蒙蔽了汉语的特性或者说“面貌”,就像即便穿着笔挺的西装，相貌却还是中国的，无法蒙人。

张东荪先生援引了高本汉所分析的例句：Albert's mother gives him cakes.这个英文句子中哪个词是主语，几乎一望便知，拉丁文和希腊文中的句子，也是如此。

当高本汉认为西方语言是一种进化了的语言时，张东荪却一针见血地指出：“中国言语与外国言语是构造上的不同，无所谓进化与不进化。

The text is about animals’ .A．special training B．great potentialsC．unique jobs D．high intelligenceBAfter being attacked by Hurricane Ida’s 150 mph winds and torrential rains, hundreds of thousands of Gulf Coast residents were left without power and fresh water this week as a 100-degree heat wave settled over the region. Ida smashed into Louisiana as a Category 4 hurricane, ripping off roofs, knocking out transmission lines, flooding roads, and reducing some brick buildings in downtown New Orleans to rubble. At least eight people died in the storm and the toll is expected to rise as emergency workers search wrecked homes and businesses.One of the most powerful hurricanes to ever hit the U.S. mainland, Ida brought a 5 to 12-foot storm surge that covered low-lying communities in southeastern Louisiana. Grand Isle is now “uninhabitable,” said Parish President Cynthia Lee Sheng, with 3 feet of sand covering the entire barrier island and 40 percent of the buildings completely destroyed.The storm caused a citywide blackout in New Orleans, but a Hurricane Katrina-level disaster was avoided there, thanks in part to the $ 14.5 billion spent on new levees, seawalls, and pumps after the 2005 storm. Experts are warning that Ida could worsen the Covid crisis in the Gulf Coast, as residents crowd together in homes and emergency shelters without immediate access to testing or medical care. ICUs in Louisiana, Mississippi, and Alabama hospitals were already near capacity be- fore the storm hit. Nearly 1 million people are still without power across Louisiana, and authorities waned it could be weeks before electricity is restored. “If you have already evacuated,” said Gov. John Bel Edwands, “do not return here.”；10. Which of the following best describes Hurricane Ida?A．Mild. B．Destructive. C．Uncontrollable. D．Impressive.；11. What does the underlined words “the toll” mean in Paragraph 1?A．The death number. B．The heat wave.C．The wind speed. D．The citywide blackout.；12. What is one of the reasons for Grand Isle to be uninhabitable?A．The entire island is covered with sand. B．It is one of the low-lying communities.C．The residents there can't wait to leave. D．Over half of its buildings were in ruins.；13. What can be inferred about the attitude of Gov. John Bel Edwards towards the prospect of Louisiana?A．Ambitious B．Undoubted. C．Indifferent. D．Unconfident.CPangolins (穿山甲) are the most trafficked (非法交易) mammals in the world and are facing extinction. To draw attention to these scaly (有鳞片的), anteater-like animals, a new wildlife documentary, Eye of the Pangolin, is attempting a u nique way to inspire action and conservation. Partnering with the non-profit organization Pangolin. Africa, the documentary was made available on YouTube in May 2019. The intention is to reach communities wherever the Internet is available, especiallyAfri can communities, who live near the animal’s habitats.Over two years, the documentary crew traveled to South Africa, Ghana, Central African Republic and Gabon in search of the four unique species of pangolin, which has never been achieved before. Filmmakers Bruce Young and Johan Vermeulen say that they went into the shoot knowing relatively little about pangolins, but grew to respect and appreciate the animals. Getting close to the creatures over two years was a crash course in these secretive creatures. Johan Vermeulen said, "One thing however that might seem unimportant is that they are actually quite fussy eaters. You would think they would eat any type of ant, but they all prefer a specific type ant."Pangolins are hunted illegally across Africa for their scales, which are used for traditional medicine, and their meat. In April 2019, Singaporean customs officials conducted two separate seizures of 24 tons of pangolin scales, which equals to the death of 69,000 pangolins.Though the documentary focuses less on the trafficking of pangolins, and more on the animals in their natural habitat, the aim of the documentary is to inspire viewers around the world to call for action to end trafficking and protecting these unique creatures.Filmed on location in South Africa, Ghana, Central African Republic, and Gabon, this powerful documentary is the story of two men on a mission to get all four species of African pangolin on camera for the very first time.14. What is the purpose of the documentary?A．To study the situation of pangolins.B．To collect fund to protect pangolins.C．To raise awareness of pangolin protection.D．To propose setting up pangolin reserves.15. What is the meaning of the underlined word “fussy” in paragraph 2?A．Picky. B．Messy.C．Showy. D．Heavy.16. What’s the documentary mainly about?A．The illegal trade of pangolins.B．The medical function of pangolin's scales.C．The life of pangolins in their natural habitats.D．The efforts of Pangolin, Africa to save pangolins.17. Where is the text most likely from?A．A brochure. B．A diary.C．A novel. D．A magazine.三、七选五阅读Ways to Boost Your Emotional Health by Improving Your Confidence Taking care of your emotional health is as important as taking care of your physical body. 18 When you feel good about yourself, it's much easier to cope with life's little ups and downs as well as bigger events.

2019高考英语江苏版精准提分练：限时训练(四)Ⅰ.单项填空1．Traditional exercises like sit-ups,press-ups and pull-ups are great for strengthening the body, you do them properly.A．since B．unlessC．providing D．considering答案 C解析providing是连词,引导条件状语从句,意为“假如……,以……为条件”。

2．—Mom! Jack has broken a cup!—It doesn’t matter.Accidents happen.A．should B．mustC．will D．shall答案 C解析句意为：——妈妈,杰克把杯子打碎了。

——没关系,意外事件是难免的。

该句看起来是考查情态动词,实际上是考查英语谚语的掌握。

accidents will happen天有不测风云,人有旦夕祸福。

3．Home is somebody notices when you are no longer there.A．that B．whenC．how D．where答案 D解析句意为：家就是当你不再住在那儿的时候才会注意到的地方。

where此处引导表语从句,意为“地点,场所”。

4．The mayor, writing the report,turned off the light,closed the door and went directly to his bedroom.A．to finish B．finishedC．finishing D．having finished答案 D解析句意为：写完这份报告之后,市长关了灯和门,径直朝他的卧室走去。

分析句子结构可知,空处应填非谓语动词,且finish与其逻辑主语The mayor之间是主谓关系,再结合题干中的“turned off the light,closed the door and went directly to his bedroom”可知,finish所表示的动作发生在并列的谓语动词所表示的动作之前,故空处应用现在分词的完成式。

答卷时应注意事项１、拿到试卷，要认真仔细的先填好自己的考生信息。

２、拿到试卷不要提笔就写，先大致的浏览一遍，有多少大题，每个大题里有几个小题，有什么题型，哪些容易，哪些难，做到心里有底；３、审题，每个题目都要多读几遍，不仅要读大题，还要读小题，不放过每一个字，遇到暂时弄不懂题意的题目，手指点读，多读几遍题目，就能理解题意了；容易混乱的地方也应该多读几遍，比如从小到大，从左到右这样的题；４、每个题目做完了以后，把自己的手从试卷上完全移开，好好的看看有没有被自己的手臂挡住而遗漏的题；试卷第１页和第２页上下衔接的地方一定要注意，仔细看看有没有遗漏的小题；５、中途遇到真的解决不了的难题，注意安排好时间，先把后面会做的做完，再来重新读题，结合平时课堂上所学的知识，解答难题；一定要镇定，不能因此慌了手脚，影响下面的答题；６、卷面要清洁，字迹要清工整，非常重要；７、做完的试卷要检查，这样可以发现刚才可能留下的错误或是可以检查是否有漏题，检查的时候，用手指点读题目，不要管自己的答案，重新分析题意，所有计算题重新计算，判断题重新判断，填空题重新填空，之后把检查的结果与先前做的结果进行对比分析。

亲爱的小朋友，你们好!经过两个月的学习，你们一定有不小的收获吧，用你的自信和智慧，认真答题，相信你一定会闯关成功。
