2020届河南省高三英语二轮复习讲义第九章并列句和状语从句

第九讲　并列句和状语从句
语法项目(一)
并列句　　　
[考纲解读·定方向]
并列句是高考考查的重点之一，重点考查上下句之间的逻辑关系，尤其在短文改错中考查and，but，or的错用；both...and，either...or，not...but...等固定搭配；while表示对比转折。

如何确定并列句
[思考趋向]
并列连词既可以连接并列的单词或短语，也可以连接并列的分句。语法填空无提示词的考查中，当两个或两个以上的单词、短语之间没有连词，一般是填并列连词。当两个或两个以上的句子之间没有连词时，就需要根据逻辑关系来判定用并列连词还是从句连词。

[典例感悟]
[典例1](北京卷)I am not afraid of tomorrow，______ I have seen yesterday and I love today.
解析：for　[句意：我不惧怕明天，因为我已经看到了昨天并热爱今天。本题考查并列连词。根据语境可知，前后分句为因果关系，故答案为for。]
[典例2](北京卷)He is a shy man, ____________ he is not afraid of anything or anyone.
解析：but/yet　[句意：他是一个腼腆的人，但是他不害怕任何事，也不害怕任何人。根据句意可知前后两个分句为转折关系，故用but/yet。]
[典例3](北京卷)Some animals carry seeds from one place to another，____________plants can spread to new places.
解析：so　[句意：一些动物将种子从一个地方带到另外一个地方，因此植物可以传播到新的地方。设空处前后两个分句之间为因果关系，故填并列连词so。]
[典例4](天津卷)Give me a chance，____________I'll give you a wonderful surprise.
解析：and　[句意：给我一次机会，我会给你一个惊喜。本题考查特殊句式中的“祈使句＋and＋陈述句”句式。故填and。]
　　　并列句解题技法
　
　　结合语境及句子结构，明晰句子之间的逻辑关系
[实例体验]
1．(2020·河北衡水中学调考)She didn't know anything about current TV shows ____________ fashion trends.
解析：or　[句意：她对于当前的电视节目和流动趋势一无所知。or用在表示否定意义的动词后表示“也不，也不是，也没有”的意思。根据本句中表示否定意义的“didn't know”可知设空处填or。]
2．(2020·江西宜春中学一次诊断)As to acute stomachache，there is no need to have an operation；all you need to do is drinking a cup of Chinese herbs，____________ the western way takes more time and money.
解析：while　[句意：对于急性胃痛，没有必要做手术；所有你需要做的就是喝杯中国草药，而西式的方法既费时又费钱。设空处表示对比，故填while。]
3．(2019·山西省重点中学协作体一模)He overcame many difficulties，____________ he was not fortunate enough.
解析：but/yet　[句意：虽然他克服了许多困难，但是他还是不够幸运。两个分句间为转折关系，故填but或yet。]
4．(2019·山东青岛一模)They quickly gave me the gun ____________ asked me if I had heard the tiger.
解析：and　[句意：他们迅速给了我那支枪并问我是否听到过那只老虎的叫声。前后为顺承关系，故用and 连接。]
[重点强化]
熟记并列连词是解题的关键
1．若表示选择，则使用or；
2．若表示转折，则使用but；
3．若表示原因，则使用for；
4．若表示结果，则使用so；
5．若表示对比，则使用while。
He found it increasingly difficult to read，for his eyesight was beginning to fail.由于他的视力开始下降，他发现读书越来越困难了。
I like English while my little sister is fond of art.
我喜欢英语而我的妹妹热爱艺术。
　牢记固定句型结构，培养做题灵敏度
[实例体验]
1．(2020·福建泉州1月质检)In China，the question is not “What shall I have？”____________ “What shall we have？”．Food is ordered to share with others，not just for oneself.
解析：but　[句意：在中国，问题不是“我吃什么？”而是“我们吃什么？”。点餐是为了和别人分享，而不是只为了自己。not...but...为固定搭配，意为“不是……而是……”。]

[重点强化]
熟记固定搭配和固定句式：
1．表示并列或递进关系的有：both...and...，not only...but(also)．..等。
2．表示选择关系的有either...or...，not...but...等；
3．祈使句＋and＋陈述句，and表顺承；

并列连词错用
解题[来源:学科网ZXXK]
攻略
常见的并列连词有：and表示顺承，but表示转折，or表示选择，so表示因果。应根据逻辑关系选择适当的连词。
典
例
1
(2019·福建龙岩2月质检)The final reward was not the number of people who attended it，nor the amount of money we raised，so the theme of the concert.
[分析]　句意：最后的成果不是参加这场音乐会的人数，也不是我们筹集了多少钱，而是这场音乐会的主题。“not...but...”为固定搭配，意为“不是……而是……”。故so改为but。
典
例
2
(2019·江西赣中南五校一模)I am going to tell you the long but rich history of Xi'an.
[分析]　句意：我将告诉你西安漫长且丰富的历史。long与rich不是转折关系，而是并列关系，故将but改为and。
典
例
3
(2019·郑州质量预测)Should I tell him the truth，and should I pay to repair it？I wish for your advice.
[分析]　考查连词。根据语境可知，此处表示逻辑上的选择关系，故用连词or。故and改为or。

并列连词多余或缺失
解题
攻略
although/though和but，because和so不能连用，一般去掉but或so；另外，一个从句只能有一个引导词。或并列句应该加连词。
典
例
1
(2019·河南郑州一中阶段检测Ⅵ)Local people live in old houses，they are very friendly.
[分析]　句意：当地的人们住在旧房子里，他们非常友好。前后两个分句为顺承关系，故在they前加and。
典
例
2
(2019·广东七校联考)Although I was tired，but I really had a good time.
[分析]　although 不能和but连用，能和yet连用。补充：此处也可删除Although，但是语意上没有删除but好。故删除but或but改为yet。

语法项目(二)
状语从句
[考纲解读·定方向]
状语从句主要考查考生对连词词义记忆并熟练运用于解题的能力，尤其是时间状语连词(when，while，as，until，before，since)；条件状语连词(if，unless)；地点状语连词(where，wherever)；结果状语连词(such/so...that)等。



并列句和状语从句的区别
[思考趋向]
并列句是连词连接两个“互不依存的主谓结构”，两者之间是并列关系，而在状语从句中前后两个句子一个是主句，一个是从句，从句是用来修饰主句的。
[典例感悟]
[典例1]①____________ you take the medicine，you will be all right.
②Take this medicine，____________ you will be all right.
解析：①If；②and　[两个题都应该填连词。句①空格处引导条件状语从句表示“如果”，故填If；句②中两个并列分句是顺承关系，故填and。]
[典例2]①____________ money is necessary for a happy life，it can't buy happiness.
②Money is necessary for a happy life，____________ it can't buy happiness.
解析：①Although/Though；②but　[两个题都应该填连词。句①空格所在句子是让步关系，故填Although/Though；句②前后是转折关系，故填but。]

2．(2018·天津卷)Let's not pick these peaches until this weekend so________they get sweet enough to be eaten.
解析：that　[句意：到周末我们再摘这些桃子吧，那样的话它们就变得足够甜能吃了。本题考查状语从句。由设空处后的内容可判断设空处引导目的状语从句，故答案为that，即so that引导目的状语从句。]

31st，JulySunny
It was sunny today and I was in a good mood.Tired of studying or the noise of city life，I came to the ecology park to enjoy scenery and get relaxing in the afternoon.[来源:学§科§网]
While I arrived at the park，what came into its sight were the thick green trees.The air is fresh.In addition，I could clearly see a path around the pond.Lying on the grasses decorated with various flowers，I felt with ease because all that I wanted was peace inside.
Therefore，with time going by quickly，the sun was setting in the west.So I had to return back home.I would never forget such romantic experience，which was really beyond description.
