高考英语冲刺复习考点通关大全：专题01 构词法
专题01 构词法高考英语冲刺复习考点通关大全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。
另附高考复习方法和考前30天冲刺复习方法。
【考点详解】【命题解读】分析近三年年高考卷，仅在语法填空中涉及到构词法中的就有两到三个小题。
可知，近年高考越来越注重对构词法的考查。
通过引导学生掌握构词法，分析词的组成，有助于学生提高词汇的分析能力，扩大词汇量。
此外，利用构词法还有助于记住单词的形、义和词性，避免出现拼写的错误，提高综合能力。
【考点预测】预计2023年高考将侧重考查词性的转换，命题侧重对名词、形容词、副词的转换的考查。
【复习建议】1.掌握派生法、合成法、转化法2.侧重培养通过语境上下文的推理判断词性的能力3.注重词汇积累考点一（派生法）派生法就是由一个词根加上前缀或后缀构成另一个词。
词根是派生词的基础，而词缀起到决定派生词的词汇意义和语法属性的作用。
（一）形容词的后缀和前缀1. 名词+-cial--形容词benefit--beneficial 有益的office--official 官方的face--facial 面部的race--racial 种族的finance--financial 金融的society--social 社会的【典例剖析】(2022全国卷乙卷) l provide ___________ (finance) aid and other benefits for local peoples.【答案】financial【解析】设空处后面有名词aid，充当provide的宾语，故修饰名词应当使用形容词作定语。

八年级英语外研版下册(考点剖析+典题精讲)5
Module 5Problems初中英语考点剖析与典题精讲系列三点剖析单词·典句·考点able adj.能够【巧记提示】table（n.桌子）→able(adj.能干的)【经典例句】They were able to get away from the fire.他们能从大火中逃生。
【考点聚焦】1）派生词：ability n.能力;本领反义词：unable adj.不能的;不会的2）构成短语be able to相当于can,后面接动词原形，表示“能够”。
但是can只有现在和过去(could)两种时态，而be able to还可用于一般现在时态和将来时态。
beat v.打；打败【巧记提示】b+eat(v.吃)【经典例句】He beat all the other players and became the best one.他打败所有其他的队员，成为最棒的一个。
【考点聚焦】1）注意beat的过去式和过去分词分别是：beat; beat2)注意beat和win之间的区别：beat与win作“战胜;打败”讲时，主要区别反映在后面的宾语上。
beat后面的宾语应当是“人”，即比赛或是战斗的对手。
win后面的宾语是“物”即比赛；战斗；战争；奖金；金钱等。
shame n.惋惜的事;遗憾;羞耻【巧记提示】name(n.名字)→shame(n.羞愧)【经典例句】What a shame that it rained today.今天下雨了，真可惜。
【考点聚焦】1）构成句式：It’s a shame...表示“做……真遗憾/羞愧”，注意本句式后面只能接动词不定式或是that从句，不能接动名词。

英语四级语法考点复习：able
形容词able的用法说明：
1.表示“有能力的”、“能干的”，可用作表语或定语。
如：
He is an able manager. 他是位有能力的经理。
He is old but still able. 他虽年老，但仍有很能干。
2.用于be able to do sth(能或会做做某事)。
如：
He is able to speak English. 他会说英语。
Everyone here is able to type. 这儿的每一个人都会打字。
He will be able to get about in a week or two. 再过一两个星期左右他就能走动了。
He studied hard and was able to pass his examinations. 他学习很努力，所以考试及了格。
注：be able to 不仅有多种时态形式(通常不用于进行时或与be going to 连用)，而且还可以与某些情态动词连用(通常不与can 连用)，甚至还可以有非谓语形式。
如：
Since his accident he hasn't been able to leave the house. 自出事之后，他一直未能离开家。
You might be able to persuade him. 你也许能够说服他。
I hope to be able to do the work. 我希望能干得了这项工作。
I regret not being able to help her. 我很遗憾未能帮助她。
3.able 的比较级和最高级通常是abler和ablest，也可以是more able和most able，有时还可用betterable和best able.如：
You are better able to do it than I (am). 你比我更有能力做这件事。
She's the person best able to cope. 她是个最能妥善处理问题的人。
4.若要加强语气，其前除可very，quite，perfectly等修饰外，有时还可用well修饰。
如：

若受just，only just修饰，则表示“只能”“仅能”。
如：

5.able的反义词是unable(不能的，不会的)，不是disable，后者是动词，其意为“使残废”“使无能力”。
比较：
They were unable to reach a decision. 他们没法做出决定。
Now that he was disabled, his house had become a prison to him. 因为他残废了，他的房子就成了他的牢笼。
