2021届高考英语语法填空之连词与状语从句
一:知识储备
1.确定填并列连词
无提示词,设空前后是两个并列成分,如两个主谓完整的句子、单词、短语等;而且相并列的成分之间是并列、转折、选择或因果关系,此时需填并列连词。
2.3个技巧要熟用
技巧1关系分析法
分析设空前后两句话的关系,确定用哪个并列连词。
①表并列或顺承关系:用and
②表转折关系:用but
③表选择关系:用or
④表因果关系:用so(因此),for(因为)
⑤表对比关系:用while
技巧2搭配法
①表并列关系:as well as“也”;both...and...“二者都……”;not only...but also...“不但……而且……”。
②表选择关系:either...or...“不是……就是……”;neither...nor...“既不……也不……”;not...but...“不是……而是……”。
技巧3句型法
①祈使句+and/or十陈述句,如表顺承用and,表转折用or。
②when作并列连词的常用句型:
be about to do...when...;be doing...when...;be on the point of doing...when...;had just done...when...;hardly...when...等。
3:确定是状语从句
设空前后两个句子之间含有一定的逻辑关系时,应用状语从句的引导词。
3.2个关键点
(1)重点关注几组引导词用法
让步状语从句though/although,as,even if/though,while,however,whether...or...,whatever,whoever,no matter how/what/which等
①动作同时发生:when,whenever,while,as等。
②动作接连发生:as soon as,the minute,immediately,once等。
③先后发生:before,after等。
④动作的延续:since。
⑤动作的终止或开始:till/until。
二:真题精析
1.I work not because I have to,_but__ because I want to.
解析:考查连词。与前面的not一起构成not...but句型,该句型意为“不是……而是……”。
2.In much of Asia, especially the so-called “rice bowl” cultures of China, Japan,Korea,_and__ Vietnam, food is usually eaten with chopsticks.
解析:句意:在亚洲大部分地区,尤其在中国、日本、韩国和越南的称为“饭碗”文化中,食物经常是用筷子吃的。China,Japan,Korea和Vietnam之间是并列关系,故用and连接。
3.But the river wasn't changed in a few days _or__ even a few months.
解析:句意:但是河流不是几天甚至几个月就改变了的。根据but及句意判断,此处要填一个表示递进含义的词,故用or。or even“甚至”。
4.It was time for her to have a new baby, _and__ it was also time for the young panda to be independent.
解析:句意:是她有一个新宝宝的时候了,也是小熊猫独立的时候了。两个完整的独立的句子应该用连词相连。上下句之间为并列关系,故用and。并列连词可以连接平行的词、短语或句子。
5.One day, the cow was eating grass _when__ it began to rain heavily.
解析:句意:一天,这头奶牛正在吃草,突然下起了大雨。be doing sth...when...是固定结构,意为“正在做某事……这时……”,when是并列连词。意为“这时……”。
6.It asks you to act like water; to be flexible as well _as__ strong.
解析:句意:它要求你表现得像水一样;柔韧又坚强。as well as“以及;和”,是固定短语。用来连接两个并列成分,作用相当于and。
7.Our rooms hadn't been reserved for that week, _but__ for the week after.
解析:句意:我们的房间预订的不是那一周,而是后一周。根据前面的not判断,本空填but,not...but...不是……而是……。
8._Unless__ you can sleep well, you will lose the ability to focus, plan and stay motivated after one or two nights.
解析:考查连词。句意:除非你能睡好,否则一两个晚上之后,你会失去专注、计划的能力和保持积极性。Unless除非,如果不。
9._Although/While/Though__ birds use their feathers for flight, some of their feathers are for other purposes.
解析:句意:尽管鸟类用它们的羽毛来飞行,可是它们的羽毛还有一些其他用处。设空处引导让步状语从句。
10.If you don't understand something, you may research, study, and talk to other people
_until/till__ you figure it out.
解析:句意:如果你不明白某件事情,你可以去调查、研究并与其他人商讨,直到你弄明白为止。设空处引导时间状语从句,表示“直到……为止”,故用until/till。
11.Located _where__ the Belt meets the Road, Jiangsu will contribute more to the Belt and Road construction.
解析:句意:位于“一带”和“一路”的交汇处,江苏将对“一带一路”的建设贡献更多。设空处引导地点状语从句,且在从句中作地点状语,因此用where引导。
12._When/If__ it cried,she rocked it back and forth and gave it little comforting pats.
解析:句意:当熊猫宝宝哭的时候/如果熊猫宝宝哭.猫妈妈会轻摇并轻拍它。根据语境可知用When/if引导时间状语从句,注意在句首,首字母应该大写。
13._Before__ she could react, I gave her a big hug and told her she didn't need to keep it a secret from me.
解析:句意:母亲还未来得及做出反应,我就给了她一个拥抱。根据句意可知该句用Before引导时间状语从句,表“在……之前”。
14.Tom is so independent that he never asks his parents' opinion _unless__ he wants their support.
解析:考查连词。句意:汤姆是如此独立,以至于他从来不征求父母的意见,除非他想得到他们的支持。unless除非。
