And I’m excited to discover that I love them just as much now as I did when I was her 1 . There are a lot of 2 for that. Laura Ingalls Wilder was a 3 write r. She’s simple and always crystal clear, but at the same time, she uses so much detail and has such a great sense of the rhythm of 4 that her writing is beautifully poetic and always a joy to 5 aloud. And the characters, of course, are among the most beautifully drawn characters in literature: the bad-tempered Laura who has such a hard time doing what she’s 6 to do, her perfect sister Mary, her strict but kind parents. 7 the animals in the book come across as 8 characters. No matter how tired I am in the evening, I 9 look forward to getting out Little House and reading a chapter 10 two.Those were the things I 11 about it as a child, and still love now. But as a（n）12 I’ve also come to appreciate how 13 American this book is. It’s the kind of book that makes you think about our heritage（传统）, and makes you 14 to be American. In these books, Laura and her family keep facing 15 and meeting them head-on. When necessary, they pick themselves up and move on to a new place, 16 from the very beginning. They don’t expect anything from 17 , and yet they care about their community and their 18 . You often hear the words “pioneer spirit” used to 19 America’s best values, but after you read Little House that’s not a（n）20 phrase. You, and the child you read it to, understand it in your heart. 1．A．age B．speed C．state D．level2．A．lessons B．examples C．reasons D．results3．A．beautiful B．positive C．difficult D．wonderful4．A．language B．education C．poem D．story5．A．speak B．say C．read D．tell6．A．encouraged B．allowed C．supposed D．ordered7．A．Ever B．Even C．Still D．Yet8．A．important B．strange C．bad D．interesting9．A．sometimes B．always C．never D．seldom10．A．but B．and C．or D．than11．A．understood B．reminded C．loved D．thought12．A．character B．teenager C．individual D．adult13．A．exactly B．specifically C．typically D．especially14．A．brave B．proud C．nervous D．curious15．A．opportunities B．hardships C．comments D．honors16．A．playing B．watching C．growing D．starting17．A．somebody B．nobody C．everybody D．anybody18．A．colleagues B．students C．neighbors D．children19．A．consider B．describe C．introduce D．explain20．A．open B．wrong C．empty D．intelligentⅥ．阅读理解You might think I’d have little in common with a camel, but we do share one useful skill: both of us can go for a very long time without water. Usually I start my day with a cup of tea, and then I might have a glass of water with my lunch and one with dinner, that’s about a liter of liquid in 24 hours. It feels like plenty, but apparently it’s not nearly enough.After years of suffering headaches and poor digestion I spoke to a neurologist about my regular headaches and a nutritionist about my poor digestion, and both told me I should be drinking up to three liters of liquid a day for my body to function at its best. I decided to conduct an experiment. What would happen if I drank the recommended amount every day for a month?The photograph of me taken the day I started this trial demonstrates（展示）perfectly and rather frighteningly what a lack of hydration does to a face. I am 42, but have to admit I look more like 52 in this picture, which is shocking. There are dark shadows under and around my eyes, which makes me look exhausted, a profusion of wrinkles and strange reddish blotches, and my skin lacks any luster（光泽）. It looks dead. Even my lips look shriveled（皱缩的）. This is all classic evidence of poor hydration, apparently.Every system and function in our body depends on water. It flushes toxins from the vital organs, carries nutrients to cells, provides a moist environment for ear, nose and throat tissues, and eliminates waste.Not drinking enough means all these functions become damaged. So I decided to see how I would look and feel if I drank three liters of water every day for 28 days. The results were astonishing.1．Which statement is NOT true according to Paragraph 1?A．The author drinks about a liter of liquid every day.B．The author has something in common with a camel.C．The author actually has plenty of water in her daily life.D．The author thinks she drinks enough water every day.2．The author’s lack of hydration caused the following physical responses EXCEPT________.A．shriveled lipsB．dark shadows around her eyesC．enough luster of her skinD．wrinkles and blotches on her face3．According to the passage, the author most probably tends to tell us________.A．the more water one drinks, the healthier he is B．it’s necessary to follow specialists’ instructions C．drinking water makes ladies look younger D．drinking enough water is key to one’s health 4．What will be probably written in the next paragraph? A．The author had her health greatly improved. B．The author gave up the experiment.C．The author suffered a lot from the experiment. D．The author felt very disappointed at the result.特殊句式和主谓一致＋完形填空＋阅读理解答案Ⅰ．1．Wears2．Are3．Means4．is published; is5．have been chosen6．is7．Are8．Is9．Stands10．is studyingⅡ．1．can the patients be treated properly in this hospital2．did he realize the love we have for our families is important3．Never will I make4．will I speak to him againⅢ．1．When is it that our school will hold the sports meeting?2．It was not until near the end of the letter that she mentioned her own plan.3．It was with the help of the local guide that the mountain climber was rescued.4．Do tell me the truth, or I can’t help you.Ⅳ．1．I2．Happy3．write to you4．they are going abroadⅤ．1~5．ACDAC 6~10．CBDBC 11~15．CDCBB 16~20.DDCBC Ⅵ．1~4．CCDA特殊句式和主谓一致＋完形填空＋阅读理解解析Ⅴ.1．根据空前的“now”及“I did when I was”可知, 随着时间的推移, 作者对这套书的喜爱并没有发生变化, 即像女儿这么大年龄（age）时, 就喜欢这套书.因此.2．根据下文的内容可知, 作者在讲她喜欢这套图书的原因（reasons）.3．从下一句“她的语言简洁清晰, 细节丰满, 语言如诗”可知, Laura Ingalls Wilder是一个出色的作家, 故用wonderful.4．由空前的内容及空后的“her writing is beautifully poetic”来看, 作者介绍的是Wilder写的小说的语言特点. 5．由上文的“rhythm”以及“beautifully poetic”等词可以看出, 她的小说适合于大声读.上文“started reading”也是暗示.6．be supposed to do sth.“应该做某事, 被期望做某事”, 为固定搭配.7．根据上文作者对这部小说的赞美之词可推断, 此处应是说“甚至（Even）连在小说中偶尔出现的动物也变成有趣的角色”.8．参见上题解析.9．依据作者对这部小说的喜爱, 她应是无论多么累, 都总是渴望取出《小木屋》, 读上一章或两章. 10．参见上题解析.11．从下文“still love now”可知答案.12．由上文“to my sevenyearold daughter”可知, 作者现在为成年人.13．作为一个成年人, 作者渐渐地意识到这本书是典型地带有美国特色的书.根据下文中的“our heritage（传统）” “to be American” “America’s best values”可知答案.14．就是这本书使我们想到自己的传统, 并且对作为一位美国人感到非常自豪.proud“自豪”.15．根据文中的“meeting them headon” “from the very beginning”这些正面的词语可知, 在这些书中, 劳拉和她的家庭面临艰难困苦, 但能勇敢地面对.opportunity“机会, 机遇”;hardship“艰难, 困苦”;comment“评论”;honor“荣誉”.16．根据“move on to a new place”可推知, 他们应是重拾精神, 从头再来.17．他们从不渴望在别人身上得到任何东西.anybody“任何人”.18．根据“community”可知, 应选“neighbors”.19．你经常会听到用“开拓精神”这个词来描述美国的最佳价值观.20．读了《小木屋》之后, 你就会知道开拓精神不再是一个空洞的词.empty“空洞的”.Ⅵ.1．细节理解题.根据第一段中的“Usually I start my day with a cup of tea, and then I might have a glass of water with my lunch and one with dinner, that’s about a liter of liquid in 24hours.”可知, 通常作者会早上喝一杯茶, 然后可能中午吃饭的时候喝一杯水, 晚上吃饭的时候再喝一杯水——也就是大约24小时内喝1升水.因此, 作者在每天的生活中喝水并不多.故项.2．细节理解题.根据第三段中的“There are dark shadows under and around my eyes, which makes me look exhausted, a profusion of wrinkles and strange reddish blotches, and my skin lacks any luster（光泽）. It looks dead. Even my lips look shriveled（皱缩的）.”可知项.3．作者意图题.文章作者通过自己听从了医生的建议每天坚持喝足够的水, 并使自己的身体发生了惊人的改变这件事告诉我们, 每天喝足够的水对健康有好处.故项.4．推理判断题.根据最后一段中的“So I decided to see how I would look and feel if I drank three liters of water every day for 28days.The results were astonishing.”可知, 作者决定看看如果她连续28天每天都喝下3升的水, 那么她看上去和感觉会怎样.结果是惊人的.由此可推知接下来讲的应该是她的身体得到了改善.。

高三英语主谓一致试题答案及解析1. The drug used to treat this disease causes bad side effects, some of which ________ deadly. A．is B．areC．was D．were【答案】B【解析】B 考察主谓一致。
Some of which引导非限制性定语从句，在从句中做主语，修饰先行词bad side effects，故从句中使用复数形式，由此排除AC，由主句的时态和语境可知表示客观性，故使用一般现在时。

单数名词分别用each修饰，作并列主语是，谓语动词要用单数，排除B,D；they each作主语时，根据后面的their，可知指的是复数，所以第二空用复数形式。
所以选C。
3. (2013·山东济宁一模)How close parents are to their children ________ a strong influence on the development of the children's characters.A．having B．hadC．has D．have【答案】C【解析】选C考查主谓一致。
句意：父母对他们的孩子们的亲近程度对孩子们的性格培养有很大影响。

2021年高三英语 语法专题主谓一致 Word版含答案
2021年高三英语语法专题主谓一致 Word版含答案在英语句子里，谓语受主语支配，其动词必须和主语在人称和数上保持一致，这就叫主谓一致。
寻其规律，大致可归纳为三个原则，即语法一致、逻辑意义一致和就近一致原则。
一、就近一致原则1．由or，not only...but also...，neither...nor...，either...or...，whether...or...，not...but...等连接两个或两个以上的并列主语时，通常根据就近一致原则，谓语动词要与离它最近的主语在数上保持一致。
Neither his parents nor I am able to persuade him to change his mind.他的父母和我都不能说服他改变主意。
2．here/there引导一个句子而主语又不止一个时，通常根据就近原则，谓语动词要与离它最近的主语在数上保持一致。
Here is a ruler，a few pencils and two copybooks.这里有一把尺子、一些铅笔和两本字帖。
二、意义一致原则1．谓语动词必须用单数的情况(1)表示学科的名词以及works(工厂)，news(消息)等作主语时，虽然本身为复数形式，但表示单数意义时，谓语动词仍用单数。
Politics is his favorite subject.政治是他最爱的科目。
(2)表示某些组织机构的名词、书/报名、国名、地名等作主语时，虽然形式上是复数，但所表示的意义是单数，所以谓语动词用单数。
Do you know when the United Nations was set up?你知道联合国是什么时候建立的吗？2．谓语动词必须用复数的情况表示总称意义的名词，如people，police，public，cattle等作主语时，谓语动词用复数。
The police are searching for the murderer.警察正在搜捕杀人凶手。
高考英语大题满分专题练习：专题9 语法填空(原卷版)
专题9 语法填空（原卷版）距离高考还有一段时间，不少有经验的老师都会提醒考生，愈是临近高考，能否咬紧牙关、学会自我调节，态度是否主动积极，安排是否科学合理，能不能保持良好的心态、以饱满的情绪迎接挑战，其效果往往大不一样。
以下是本人从事10多年教学经验总结出的以下学习资料，希望可以帮助大家提高答题的正确率，希望对你有所帮助，有志者事竟成！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。

（完整版）高考英语专题复习主谓一致（附答案）.doc
（完整版）高考英语专题复习主谓一致（附答案）.doc高考英语专题复习主谓一致（附答案）I.考点分析一、概述主谓一致是指句子成分之间或词语之间在人称、性、数等方面的一致关系。
处理主谓一致一般应遵循以下三条原则：1.语法一致，即在语法形式上取得一致。
例如，主语为单数形式，谓语动词也为单数形式；主语为复数形式，谓语动词也采取复数形式。
a. The number of errors was surprising.b. Julia and her twin sister naturally look a lot alike.2.意义一致，即从意义着眼处理一致关系。
a. The crowd were fighting for their lives. (单形名词主语要求复数谓语动词，下划线部分表示一个整体中的成员 )b. Five minutes is enough. ( 复数名词单数谓语动词，下划线部分表示一个数目)3.邻近原则，即指谓语动词的形式与邻近的名词一致。
a. A man of abilities are needed（.动词 are 不与主语 a man一致，而与其邻近的复形名词a bilities 形式上一致。
二、主谓一致注意要点：1.当名词词组中心词为表示度量、时间等复数名词时，往往可根据意义一致的原则，把这些复数名词看作一个整体，谓语动词采取单数形式。
a. The dollars is not enough.b. Three months passes in no time at all on the ranch.如果明显地指一个个个体，则要根据语法一致地原则，谓语动词用复数形式。
a. There are two sliver dollars in each of the stockings.2.如果名词词组中心词是all, most, half, the last, the rest, the remainder等词组时，其主谓关系一般遵循意义一致的原则：如所指为复数意义，谓语动词用复数形式；如所指为单数意义，则谓语动词用单数形式。
高考英语语法专题复习：主谓一致(含练习题及答案)
高考英语语法专题复习：主谓一致名师箴言：主谓一致指的是句子的谓语动词与其主语在数上必须保持一致。
名师导航：第一关： 1. 语法一致原则的阐述语法一致原则 2. 语法一致原则的用法语法一致原则的阐述：主语和谓语动词之间的一致关系主要表现在“数”的形式上，即用作主语的名词词组中心词和谓语动词在单复数形式上的一致。
如果名词中心词是复数，动词就改用复数形式；如果名词中心词不是复数，而是单数名词或不可数名词，动词便用单数形式。
语法一致原则的用法：1.单数名词、代词、动词不定式短语、动名词短语或从句做主语时，谓语动词一般采用单数形式。
名词做主语：The student is clever.这个学生很聪明。
代词做主语：He is doing the experiment.他正在做实验。
动词不定式做主语：To go to bed early and to rise early is a good habit.早睡早起是个好习惯。
动名词做主语：Persuading him to join us seems really hard.劝他加入我们看起来确实困难。
主语从句做主语：Whatever was left was taken away.无论剩下什么都被拿走了。
Whether we will go out for an outing tomorrow depends on the weather.我们明天去不去郊游取决于天气。
警示灯：一个主语从句做主语，谓语动词一般用单数形式。
但若从句谓语或从句后的表语是复数形式，则谓语动词用复数形式。
What they need are books.他们需要的是书。
2.当主语是and, both…and 连接的并列结构时，如果主语指的是两个或两个以上的人或物，谓语动词用复数。
Tom and Jack were close friends.汤姆和杰克是亲密的朋友。
Both rice and wheat are grown by farmers in China.中国的农民既种植大米也种植小麦。
