高考英语语法词汇专项突破：代词考点专题全突破+巩固训练养成良好的答题习惯，是决定高考英语成败的决定性因素之一。
做题前，要认真阅读题目要求、题干和选项，并对答案内容作出合理预测;答题时，切忌跟着感觉走，最好按照题目序号来做，不会的或存在疑问的，要做好标记，要善于发现，找到题目的题眼所在，规范答题，书写工整;答题完毕时，要认真检查，查漏补缺，纠正错误。
总之，在最后的复习阶段，学生们不要加大练习量。
在这个时候，学生要尽快找到适合自己的答题方式，最重要的是以平常心去面对考试。
英语最后的复习要树立信心，考试的时候遇到难题要想“别人也难”，遇到容易的则要想“细心审题”。
越到最后，考生越要回归基础，单词最好再梳理一遍，这样有利于提高阅读理解的效率。
另附高考复习方法和考前30天冲刺复习方法。
[命题热点]代词结构种类很多，有人称代词、反身代词、物主代词、疑问代词、指示代词、连接代词、关系代词、不定式代词、替代词以及it等。
从命题角度看主要考查代词词义的区别，如that/one/it；代词功能的区别，如me, oneself, she, ours；含有代词的固定短语，如make it/give me five; 反身代词的用法，如help oneself, enjoy oneself; 比较中的代词用法；反义疑问句中的代词；不定代词用法；疑问代词与疑问副词辨析。
从历年高考题来看，不定代词和替代词的考查是重点。
试题设置了一定情景干扰，题干句的语法结构十分重要，重点考查考生在语境中灵活运用代词的能力。
考点1 人称代词的主格与宾格_____(I), too. I was a little stressed out about this new store, but now I'm feeling much more confident.详解：Me。
根据答句后面的I看出前面是第一人称单数，再根据单独使用得出用宾格代词代替主格代词，用Me。

高三英语复习教案精选篇1一、指导思想根据英语教学规律，以新课程标准为准绳，以《河南省新课程考试说明》为依据，以巩固和落实基础知识为中心，以培养和读写能力为重点，反对低层次的重复操练，代之以阅读能力培养为主线，突破词汇学习，联系学生的实际情况，充分发挥学生潜能，关注学生非智力因素，调动学生学习积极性，扎扎实实抓好双基，通过综合训练，培养学生运用知识的能力，努力提高学生的综合素质和解题技巧，以适应新课标的高考要求。
二、学情分析1、本届学生18个应届班，学生1100多人，学生英语科底子薄，水平参差不齐。
2、新教材的词汇量大，内容多，相对而言高一、高二的教学课时与兄弟学校相比，不多。
加之，教材推进得比较快(尤其是高二)，部分学生基础知识掌握得不够好，单词遗忘得很多。
3、学生写作训练不够。
高一、高二两年几乎没有写作训练，而写作在高考中占有很大的比例，但这却是我校学生的薄弱环节。
三、复习计划第一阶段：第一轮复习(20__年8月27日—20__年2月下旬)这一阶段为1~8模块的复习。
第一轮复习的宗旨：以本为本，夯实基础，适度提高能力。
第一轮复习教学以抓“双基”为主，完成知识的原始积累，把模块中的语言知识和语法项目进行比较、重组、总结，努力帮助学生输理知识结构，建立知识网络，掌握基本语法规则，打好扎实的语言基础。
复习时应充分发挥学生的主体作用。
精选一轮复习资料，一单元一案，每单元4x5课时，每周一次拓展练习。
注重阅读训练，2—3篇/日;强化书面表达训练，1篇/周(25分钟左右);书面表达常用的词、短语、句子记录背诵。
每天有一定量的词汇要求学生记忆，保证学生早、晚每次10分钟，重复记忆(要背诵的词、短语、句子列在平时的练习中)。
计划至20__年2月下旬结束第一轮复习。

There was nothing but wide-open fields for miles and miles around our rural Minnesota home. We never saw strangers not ever and here on this hot evening was a real live one walking up our driveway.A young man, a slightly-built hitchhiker (搭便车的人) approached our door. He knew there was a storm coming, and he desperately needed shelter. Not wanting to intrude on our home and family, he asked my dad if he could sleep in our basement for the night for protection from the rain. Instead of saying yes, my dad loaded us all up in the 1959 Chevrolet: five kids, my mum, and the man.Our family consisted of three older children whose father had died young and three more children from the union of my mother and father. Our older brother Jerry was in the Navy, on a ship somewhere overseas. Our mum and dad worried about him.We drove him 10 miles to the next town, where Dad bought the man a room for the night along with a hot evening meal. In the car after we dropped off the stranger, I heard my dad say to my mum, “I just hope that if Jerry ever needs anything, this kindness will be returned to him.”Weeks later, Dad told my uncle about the young man. My uncle suggested that perhaps my dad shouldn’t have taken the risk of having a stranger in our car. My dad replied, “You are absolutely right. I should have invited him into our home.”4．What does the underlined phrase “intrude on” in paragraph 2 mean?A．Disturb.B．Scare.C．Embarrass.D．Upset. 5．How did the author’s father help the stranger?A．By providing a bed for him in the basement.B．By letting him stay for the night in the car.C．By taking him to a hotel in another town.D．By cooking a hot evening meal for him.6．What do we know about the author’s family?A．The family had five children in total.B．Jerry was serving in the army in the USA．C．They had no spare room for the hitchhiker.D．Dad wished his elder son to be treated kindly.7．What did the author’s uncle think of his father’s deed?A．Worthwhile.B．Inappropriate.C．Inspiring.D．Unbelievable.Almost all new parents struggle to get enough sleep while caring for their newborns. For some penguin (企鹅) parents, though, periods of sleep are especially short.Researchers recently found that Chinstrap penguins only sleep for about four seconds at a time in order to protect their eggs and newborn chicks. They do this thousands of times throughout the day. The short “microsleeps” total around 11 hours each day. The microsleeps appear to be enough to keep the parents going for many weeks.Niels Rattenborg, a sleep researcher at the Max Planck Institute for Biological Intelligence in Germany, said, “What’s surprising is that the penguins are able to function okay and successfully raise their young.”Chinstrap penguins usually lay their eggs in November in nests made up of small rocks. Mated (交配的) pairs share parenting responsibilities. One parent usually watches the eggs and chicks alone while the other goes off fishing for family meals. Adult penguins don’t face many natural enemies in the mating season. But large birds called brown skuas eat the penguin eggs and small chicks. Other adult penguins may also try to steal the small rocks from the nests, so penguin parents must always be on guard.For the first time, scientists followed the sleeping behavior of Chinstrap penguins. They did this by attaching devices that measure brain waves. They collected data on 14 adults over 11 days on King George Island off the coast of Antarctica.Won Young Lee, a biologist at the Korean Polar Research Institute, thought of the idea for the study when he saw mating penguins often blinking (眨) their eyes and possiblysleeping. But the team needed to record brain waves to confirm the animals were sleeping. “For these penguins, microsleeps have some restorative functions,” he said. He added that they would not survive without it.The researchers didn’t collect sleep data outside the mating season. But they suspect that the penguins may sleep for longer periods at other times of the year.8．What have researchers found about Chinstrap penguins?A．They take turns to take care of the young.B．They sleep for several seconds at a time.C．They rest for 11 hours in a row every day.D．They behave poorly due to lack of sleep.9．What is paragraph 4 mainly about?A．The habitats of the penguins.B．The living habits of the penguins.C．The mating seasons of the penguins.D．The natural enemies of the penguins. 10．Which of the following might Won Young Lee agree with?A．Microsleeps of the penguins matter in their survival.B．It’s difficult to record brain waves of the penguins.C．The penguins may sleep longer than people believe.D．More funds are needed to further study the penguins.11．Where is the text most probably taken from?A．A book review.B．A travel brochure.C．A science journal.D．A chemistry textbook.When people think of word innovators throughout history, male writers likely come to mind. Shakespeare is credited with inventing more than 1,700 words, including “bedroom”, “courtship” and “swagger”. Charles Dickens is said to have first used the words “butterfingers” and “doormat”, and Dr. Seuss reportedly came up with “nerd”.But despite contributions from famous writers, historians say another group has an even greater impact on the development of language: teenage girls. Women lead up to 90 percent of linguistic (语言的) changes, as sociolinguist William Labov observed in the early 2000s. In fact, he wrote, women are often linguistically ahead of men “by a full generation”.Now women are leading the charge online. Though Oxford University Press’2023 word of the year, “rizz”, meaning charm, was coined by a man, several runners-up, including“situationship” and “swiftie” were inspired or first used by women. The term “goblin mode”, which refers to lazy behavior, was Oxford’s 2022 word of the year and appears to have been first used by a woman on Twitter in 2009.It’s often impossible to tell who first used new words. But whether or not young girls invent new phrases, they are more likely to be early adopters of the latest lingo (术语), says University of Toronto linguist Sali Tagliamonte, “They’re pushing changes forward.”There are a handful of possible reasons why girls lead lexical (词汇的) innovation. According to Gretchen McCulloch, author of Because Internet: Understanding the New Rules of Language, women tend to be more socially aware. They have larger social circles and may be exposed to more language diversity. And because women tend to be caregivers, boys usually learn language from their mothers, whereas women and girls learn words from other women.12．Why does the author mention some words coined by male writers?A．To compare male and female writers.B．To introduce some well-known writers.C．To lead in the topic to be talked about.D．To put forward a point to be proved.13．Which of the following words was invented by a male?A．Rizz.B．Situationship.C．Swiftie.D．Goblin mode. 14．Who thinks women’s social awareness contributes to lexical innovation?A．Dr. Seuss.B．William Labov.C．Sali Tagliamonte.D．Gretchen McCulloch.15．What can be a suitable title for the text?A．New Words Are Added to English DictionariesB．Female Teens Take a Lead in Linguistic ChangesC．Women Are More Sensitive to Language DiversityD．New Terms Make Communication More ColorfulHow to Deal with Awkward SilencesWe all know what it’s like when a conversation dies off and you’re left to sit in silence.16 Thankfully, filling these silences isn’t as difficult as it may seem. Read on to learn how to initiate small talk and deal with awkward silences.• Think of topics ahead of time.Before attending a social event, think of a few “go-to” topics to jumpstart a dead conversation. This will help you to fill the silences instead of struggling for words in the moment. Recent news, local events, popular books and television shows are all good fallback options. 17• Ask open-ended questions.Ask questions that have more than one possible answer. 18 They help avoid resulting in short response. For example, instead of asking, “Did you like your high school?”, you could ask, “What did you like about your high school?”• 19As with any good conversation, the biggest key is to listen. If they respond to your question with a short statement such as “Yes”or “No”, that might indicate that they aren’t comfortable talking about a particular subject. Instead, talk about something that you know they're interested in. For example, “I heard you won your football game the other night. I’d love to hear about it.”• Give a compliment (表扬).20 For example, you could say, “I really like your shirt. Where did you get it?” This could move the conversation in another direction while making the other person feel good. Stick to saying nice things if you’re trying to make small talk.A．Keep the conversation flowing.B．It also allows you to spend more time together.C．Listen carefully and respond to their reactions.D．There’s only one word to describe it: awkward.E．This is always a safe bet, as long as it’s appropriate.F．Such questions are likely to get the person talking more.G．However, avoid some subjects that may cause arguments.二、完形填空Growing up on a farm, Tori James spent much of her early years outdoors, building shelters and playing in muddy streams.
