语法专项突破
考频分析
重庆大学版选择性必修第三册中,Unit 1 Choice and Decision是重点语法模块,考频占语法总量的
15%左右,贯穿试卷核心题型:单项选择(1-2题)、阅读理解(2-3题)、语法填空(1-2题)、书面
表达(核心考察,直接影响篇章逻辑与表达准确性)。在语境理解类题目中,该单元涉及的词汇辨
析、句式结构及逻辑连接往往是解题关键。
考查内容
。名词性从句综合是高中英语语法的重要模块,考频占语法总量的15%左右,主要分布在核心题型
中:阅读理解(长难句分析关键)、完形填空(1-2题)、语法填空(1-2题)、书面表达(复杂句式
构建核心)。在语法填空和书面表达中,连接词的选择、从句语序及时态一致性是考察重点。
知识点一:名词性从句综合
高中对名词性从句综合的考察聚焦三大维度
1.从句类型识别:
·主语从句、宾语从句、表语从句、同位语从句的特征与功能
2.连接词选用:
。that、if/whether、wh-类连接词(what,who,which,when,where,.why,how)的辨析与适用场景
3.语序与时态:
·陈述句语序在从句中的应用
。主句与从句时态的呼应规则
知识点二:非谓语动词
1.动词不定式(t0+动词原形,表目的、将来、未完成)

1.基本用法
。作主语:To learn English well is important..
。作宾语:She wants to buy a new book.
。作目的状语:He went to the library to read.
2.省略o的情况:
。感官动词(see,hear,watch等)后:I saw her dance.
。使役动词(make,let,have等)后:My mother made me clean the room.
3.常见固定搭配:
。want to do,decide to do,try to do,.plan to do,forget to do(忘记去做)
2.动名词(动词+ing,表主动、进行、抽象概念)
1.基本用法
。作主语:Swimming is good for health,
·作宾语:He enjoys listening to music.
●作定语:a reading room
2.常见固定搭配:
enjoy doing,finish doing,practice doing,mind doing,keep doing,be good at doing
3.分词(现在分词doing/过去分词done)
1.现在分词(表主动、进行):
。作定语:a running boy
●作状语:She sat there,reading a newspaper.
2.过去分词(表被动、完成):
。作定语:a broken cup
。作状语:Seen from the top,the city looks beautiful.
3.区别:
·现在分词与逻辑主语是主动关系:The rising sun is beautiful.
。过去分词与逻辑主语是被动关系:The risen sun is warm.
考法精析
考法一:名词性从句的时态与语气规则

A版知识点全解
1.时态一致原则
1.主句为现在/将来时,从句可根据实际情况使用任意时态
例句:
-She says(that)she will visit Paris next month
-I wonder what he did yesterday.
2.主句为过去时,从句通常用过去相关时态
例句:
-He told me that he was watching TV at 8 p.m.
-They didn't know if she had finished the work
3.客观真理/事实不受主句时态影响,仍用一般现在时
例句:
-The teacher said that the earth goes around the sun.
2.虚拟语气的使用场景
1.表达建议、命令、要求等意义的名词性从句
结构:should+动词原形(should可省略)
例句:
-The doctor's suggestion is that he(should)rest for a week.
-We insisted that she (should)attend the meeting.
2.wish后的宾语从句
对现在的虚拟:过去时(be动词用were)
例句:I wish I were as tall as you
对过去的虚拟:had+过去分词
例句:She wishes she had studied harder last term.
对将来的虚拟:would/could+动词原形
例句:We wish the rain would stop tomorrow.
3.否定前移的补充规则
1.仅适用于主句主语为第一人称(I/we)的情况
例句:Idon't think he is right.
2.主句谓语为think/believe/suppose/expect等心理活动动词
反例:Idon't know if he will come.
3.反意疑问句的附加疑问部分需与从句一致
例句:We don't believe she can swim,can she?
4.形式主语/宾语的高级句型拓展

A版知识点全解
1.It+be+过去分词+that从句
例句:It is reported that the population is increasing
2.动词+it+形容词+for/of sb.+todo
例句:I find it easy for him to solve the problem.
She thinks it kind of you to help her.
考法二:连接词that与what的辨析
核心:根据连接词在从句中是否充当成分及是否有实际意义,区分that和what的用法
真题1(语法填空):
-he will come tomorrow is certain.
答案:That
解析:从句he will come tomorrow”结构完整,不缺成分,且无实际意义,需用hat引导主语从句,
that在从句中不充当成分。
真题2(单项选择):
She always thinks ofshe can do more for others.
A that B what C if D whether
答案:B
解析:从句中缺少do的宾语,需用what引导宾语从句,what在从句中作宾语,表示”.的事情”;
that不充当成分,if/whether表示”是否”,均不符合语境。
考法三:名词性从句与非谓语动词的综合应用
核心:辨别名词性从句中连接词的选用规则,结合非谓语动词作主语、宾语或状语的用法,掌握从
句与主句的时态呼应及语序要求
真题1(单项选择):
-he will attend the meeting tomorrow depends on-the project can be finished on time.
A.If;whether B.Whether;if C.Whether;whether D.If;if
答案:C
解析:第一空引导主语从句表示“是否”,只能用whether::第二空作介词on的宾语,同样需用
whether,.if不可用于介词后或引导主语从句。
真题2(语法填空):
It is important_(remember)that_you said just now needs_(check)carefully.
答案:to remember what checking
解析:句中it为形式主语,真正主语是不定式短语to remember:第二空引导主语从句并在从句中
作宾语,用what:第三空need后接动名词表被动含义,即needs checking=needs to be checked.。

解题小妙招
连接词选看成分,不缺成分用that:缺主宾表用wat,是否含义whether佳:if不可引主从,介词
之后也不用。
语序规则要记牢,陈述语序不含糊:疑问词后接主谓,倒装结构需排除。
时态语气综合看,主句时态引从句;主过从过要一致,客观真理用现一;suggest等表建议,宾从虚
拟should加动原;It is necessary that句型,that不可省。
