2024年高考英语易错题(新高考专用)易错点07动词的时态和语态(4大陷阱)2
易错点07 动词的时态和语态目录01 易错陷阱(4大陷阱)02 举一反三【易错点提醒一】一般现在时、一般过去时和现在完成时易混易错点【易错点提醒二】一般过去时和过去完成时易混易错点【易错点提醒三】现在完成时和过去完成时易混易错点【易错点提醒四】主动语态与被动语态易混易错点03 易错题通关易错陷阱1:一般现在时、一般过去时和现在完成时易混易错点。
【分析】【高考链接】(2023年浙江卷1月)The large siheyuan of these highranking officials and wealthy businessmen often________ (feature)beautifully carved and painted roof beams and pillars(柱子).【答案】featured【解析】考查动词时态。
句意:这些高级官员和有钱商人的高大的四合院,通常以雕刻精美和被粉刷的房顶横梁和柱子为特点。
分析句子结构可知,空格处需要填谓语动词,再结合and后动词时态可知,空格处应用一般过去时。
故填featured。
易错陷阱2:一般过去时和过去完成时易混易错点。
【分析】1.下列动词hope、wish、expect、think、intend、mean、suppose等,用过去完成时表示“原本……(事实上未能……)”。
2.This/It/That was the first/second/third ... time that ...表示“这/那是(某人)第几次做某事”,that从句中要用过去完成时。
3.hardly ... when ...和no sooner ... than ...两个句型中,主句均用过去完成时。
易错陷阱3:现在完成时和过去完成时易混易错点。
【分析】易错陷阱4:主动语态和被动语态易混易错点。
【分析】➢受母语干扰,翻译上下文时混淆被动语态与主动语态。
➢混淆谓语动词被动语态构词be+done与非谓语动词重点过去分词done。
高考语法易错题解析
高考语法易错题解析一、名词性从句名词性从句是高考中常考的知识点,主要考查对从句作用和从句种类的辨析,下面我们就来研究一下名词性从句常见的易错题。
1. It is _____ I want to talk to you about.A. thatB. whatC. howD. why解析:这是一个强调句型,强调句一般以it is/was that开头。

易错点11 氮元素及其化合物-备战2023年高考化学考试易错题(解析版)
易错点11 氮元素及其化合物易错题【01】氮的固定易错题【02】氮的氧化物(1)氮有多种价态的氧化物,如N 2O 、NO 、N 2O 3、NO 2(或N 2O 4)、N 2O 5,其中属于酸性氧化物的是N 2O 3、N 2O 5。
(2)氮的氧化物都有毒,其中NO 2与N 2O 4之间存在平衡:2NON2O4,在阿伏加德罗常数问题中要考虑该平衡的存在;(3)NO 、CO 均能与血红蛋白结合而使人中毒。
易错题【03】硝酸的强氧化性与金属反应稀硝酸与铜反应的化学方程式: 3Cu +8HNO 3(稀)===3Cu(NO 3)2+2NO↑+4H 2O 浓硝酸与铜反应的化学方程式: Cu +4HNO 3(浓)===Cu(NO 3)2+2NO 2↑+2H 2O 与非金属反应浓硝酸与C 反应的化学方程式: C +4HNO 3(浓)=====△CO 2↑+4NO 2↑+2H 2O 与还原性化合物反应 硝酸可氧化Fe 2+、H 2S 、SO 2、Na 2SO 3、HI 等还原性物质。
如稀硝酸与FeSO 4溶液反应的离子方程式: 3Fe 2++4H ++NO -3===3Fe 3++NO↑+2H 2O 3中N 元素显+5价,处于最高价态,因此浓、稀硝酸均具有强氧化性,浓度越大,氧化性越强,其还原产物的价态越高。
②反应过程中,HNO 3的还原产物一般为HNO 3(浓)―→NO 2,HNO 3(稀)―→NO 。
③浓硝酸能使紫色石蕊溶液先变红,后褪色,该反应过程中浓硝酸表现出强酸性和强氧化性。
④常温下,铁、铝遇浓硝酸能发生“钝化”,表面生成致密的氧化膜,并非不发生反应,故浓硝酸可以用铁桶盛放。
易错题【04】实验室制取氨的其他方法方法 化学方程式(或原理) 气体发生装置加热浓氨水 化学方程式为NH 3·H 2O=====△NH 3↑+H 2O浓氨水+NaOH 固体 NaOH 溶于水放热,促使氨水分解。
且OH -浓度的增大有利于NH 3的生成浓氨水+CaO 固体 CaO 与水反应,使溶剂(水)减少;反应放热,促使氨水分解,化学方程式为NH 3·H 2O +CaO==NH 3↑+Ca(OH)2(1)牢记一条转化主线,侧重物质之间转化的条件及产物: N 2――→H 2NH 3――→O 2NO――→O 2NO 2――→H 2O HNO 3――→NH 3NH 4NO 3(2)结合氧化还原反应中“价态转化规律”,认识不同价态含氮物质之间的转化关系:NH 3――→O 2NO――→O 2NO 2――→H 2O HNO 3(3)明确含氮物质的连续氧化关系:N 2――→O 2NO――→O 2NO 2――→H 2O HNO 3易错题【06】(1)N 元素的非金属性强于P 元素,第一电离能大于P 元素,原子半径小于P 原子。

高考绝招:英语高手的易错题典型题宝典五套
高考绝招:英语高手的易错题典型题宝典(一)1.______late in the morning,Bob turned off the alarm clock.A.So as to sleepB.SleepingC.Tosleep D.Having slept解析:本题考查不定式作目的状语的知识。
A项. so as to 和in order to 的区别so as to只用于句子中间,in order to可以用在句子中间也可以用在句子开头,两者都表示目的状语,意思相同,都翻译为:为了……B项. 现在分词的常用法:1.表示主动 2.表示动作正在发生。
根据句意可得,B项错误C项. 动词不定式的用法:1.表示将来 2.表示动作的一次性 3.主动和被动看具体情况,详见后面的题目 4.作目的状语,意思是:为了……。
故C正确D项. Having done 的用法:表示先于谓语动词发生,且和主句的主语为主动关系,可以翻译成已经……。
带入上述句子,意思不同,不成逻辑。
错误答案:C2.What do you think of the reason ______he explained in his last letter______refusing the job?A.why,whyB.that:forwhich C.which;for D.that;because解析:本题考查定语从句和reason 一词的用法。
做从句题目首先要分清句子的主干,把疑问句改成陈述句。
What do you think of the reason( ______he explained in his last letter)______refusing the job? 括号里面的为定语从句,确定好后再分析定语从句中缺少什么成分,对了,从句中缺少expain 的宾语,故可以填which,that 或者省略。
再看后面一空,______refusing the job是与reason 搭配的,正常语序是 the reason ______refusing the job.到这里,很多学生会选择why或者because,再仔细看看便知refusing the job不是谓语动词短语,不能用连词或者疑问副词连接,两者都不对,而是用for,固定短语the reason for….意思为:……的原因答案:C3.We can communicate______people in every part of the world______the Internet.A.which;withB.with;throughC.through;throughD.t hrough;with解析:本题考查固定短语。

The first problem mentioned in the passage is that people _______.A. spend too much time on the InternetB. forget about their studies and workC. become addicted to online gamesD. become addicted to social media【错误选项】B. forget about their studies and work【解析】根据第一段第一句和第二句,我们可以知道,第一个问题是人们花太多时间在互联网上。
备战2024年高考生物易错题(新高考专用)易错点08 遗传物质探索实验中的三个误区(解析版)
易错点08遗传物质探索实验中的“三个”误区目录01易错陷阱(3大陷阱)02举一反三【易错点提醒一】探究实验结论≠DNA是遗传物质【易错点提醒二】放射性异常≠保温时间短【易错点提醒三】原核细胞的遗传物质≠RNA03易错题通关易错陷阱1:探究实验的结论都是DNA是遗传物质【分析】①格里菲思的肺炎链球菌体内转化实验:加热致死的S型细菌中含有某种转化因子,使R型活细菌转化为S型活细菌。
②艾弗里的肺炎链球菌体外转化实验:证明DNA是遗传物质,而蛋白质不是遗传物质。
③噬菌体侵染细菌实验:DNA是噬菌体的遗传物质,不能明确蛋白质是不是遗传物质。
易错陷阱2:放射性异常都是保温时间太短引起的【分析】①32P标记的噬菌体:保温时间过短,部分噬菌体没有侵染到大肠杆菌细胞内,经离心后分布于上清液中;保温时间过长,噬菌体在大肠杆菌内增殖后释放出子代,经离心后分布于上清液中,造成上清液放射性也较高。
②35S标记的噬菌体:搅拌不充分,有少量含35S的噬菌体蛋白质外壳吸附在细菌表面,随细菌离心到沉淀物中。
易错陷阱3:原核细胞(细胞质)的遗传物质是RNA【分析】真核生物与原核生物的遗传物质是DNA,病毒的遗传物质是DNA或RNA,生物界绝大多数生物的遗传物质是DNA,只有极少数生物的遗传物质是RNA。
【易错点提醒一】探究实验结论≠DNA是遗传物质【例1】人们对遗传物质的认知水平随着时代的发展而进步。

1.(2023年新高考Ⅰ卷)阅读下面的文字,完成后面试题。
天是越来越冷了,祥子似乎没觉到。
心中有了一定的主意,眼前便增多了光明;在光明中不会觉得寒冷。
地上初见冰凌,连便道上的土都凝固起来,处处显出干燥,结实,黑土的颜色已微微发些黄,像已把潮气散尽。
特别是在一清早,被大车轧起的土棱上镶着几条霜边,小风尖溜溜的把早霞吹散,露出极高极蓝极爽快的天;祥子愿意早早的拉车跑一趟,凉风飕进他的袖口,使他全身像洗冷水澡似的一哆嗦,一痛快。
有时候起了狂风,把他打得出不来气,①可是他低着头,咬着牙,向前钻,像一条浮着逆水的大鱼;风越大,他的抵抗也越大,似乎是和狂风决一死战。
猛的一股风顶得他透不出气,②闭住口,半天,打出一个嗝,仿佛是在水里扎了一个猛子。
打出这个嗝,他继续往前奔走,往前冲进,没有任何东西能阻止住这个巨人;他全身的筋肉没有一处松懈,像被蚂蚁围攻的绿虫,全身摇动着抵御。

易错点 成语-备战2023年高考语文考试易错题(全国通用)
易错点成语-备战2023年高考语文考试易错题(全国通用)一、选择题(共42 分)1.阅读下面的文字,完成后面的题。
风筝,是中国古人的一项重要发明,放风筝是一种人们喜闻乐见....的传统活动。
早期有关风筝的记载多与传递信息等军事活动有关。
到唐代,风筝开始出现在文人诗歌中。
宋代以后,逐渐演变成一种老少皆宜....的玩具,而清明时节放风筝也成为一项普及的民俗活动。
明代以后,风筝传播到世界各地,并深受各国人民喜爱。
自1984年开始,迄今已经连续举办了36届的山东潍坊国际风筝节,吸引着大批中外风筝专家、爱好者及游人前来观赏和竞技。
早期的风筝制作十分简单,用竹篾做骨架,贴上素绢或白纸,结好线绳,便可放飞了。
随着时间的推移,风筝的制作技艺不断炉火纯青....,风筝于是有了很强的观赏性和艺....,样式也逐渐丰富起来,从动物、植物、器具、文字,到人物、仙佛,不一而足术价值。
有些风筝还安装了声响装置,如著名的“板鹞”风筝,通体安装笛哨,少则数十个,多则成百上千。
放飞时百哨齐鸣,宛若空中交响乐,具有独特的魅力,大大增加了放风筝的趣味性。
文段中加点的词语使用不当的一项是( )A.喜闻乐见B.老少皆宜C.炉火纯青D.不一而足【答案】C【解析】【详解】本题考查学生正确理解和运用成语的能力。
A.喜闻乐见:意思是喜欢听,乐意看。
形容很受欢迎。
此处是说放风筝是一种很受人们欢迎的传统活动。
符合语境。
B.老少皆宜:本义指老人和儿童都适宜,喻指适用的范围非常广。
此处是说风筝逐渐演变成一种适用范围非常广的玩具。
符合语境。
C.炉火纯青:通常用来比喻技艺或学问、修养达到精粹完美的境界,用来形容“风筝的制作技艺”没有问题,但文段中“炉火纯青”前面有个修饰限定语“不断”,而“不断”表示动作行为的不间断,也有“反复进行”的意思,但达到完美的境界并不是一个能够反复进行的动作,所以此处属于用词不当。
D.不一而足:指同类的事物不止一个而是很多,无法列举齐全。
