高中英语从句语法总复习

1、常考知识在复合句中修饰名词或代词的从句叫定语从句。被修饰的名词或代词叫先行词。通过从句的意思判断先行词。引导定语从句的关系代词有who，, whom whose, which , that等和关系副词 where, when, why等。一、非限制性定语从句记：有逗号的从句，连接词一定不用 that 。典型例题They will fly to Washington,they plan to stay for two or three days.A.whereB.thereC.whichD.when二、关系代词 who, whom whose引导的定语从句这类定语从句中，who在从句中用作主语，

2、whom从句中用彳宾语，whose从句中用作定语注意：Whose既可代表人，也可代表物eg： Do you see the house whose windows are all broken?三、关系代词that 和 which 引导的定语从句1、只能用which 的情况（ 1）介词 +which（ 2）非限制性定语从句2、只能用that 的情况（1）先行词为不定代词（all , nothing , much等）（ 2）两个the ：先行词为序数词和最高级（ 3）人和物同时做先行词时（ 4）先行词被the only ， the very 修饰时3、“介词+which/whom”中介词的选择关

4、行词由“明显的地点”转为“地点的模糊化" 。Where不能只理解为表地点，当先行词表示某人 / 物的处境（situation ） ，或某事所发展的阶段，或表达某事的某个方面（ part ，point ）时都可用where 这个关系副词。例词： Place 地点 Case 案例 Situation 形势 Point 点 Top 顶点 Position 地位 Stage 阶段 Occasion 场合 Aspect 方面五、关系代词as， which 的区别As主要用于 as as; the same as；such as等结构中。译为"正如"。as 引导非限制性的定语

5、从句，修饰前面整个句子，而which 均可。eg： The meeting,which was held in the park,was a success.eg： The meeting was a success,as was expected.典型例题（ 1） My friend showed me round the town, was very kind of him.A. whichB. thatC. where D. it（ 2） The Beatles ， many of you are old enough to remember,came from Liverpool.A.

7、用关系副词。3、不完整的（ 1） * 关系代词和关系副词的辨析，判断从句是否完整，完整的连接词一定用关系副词。eg： This is the farm where he works.eg： This is the farm which he visits.*遇至U situation , part , point , place , period 等，般连接词用where。遇至U time , age, day 等，般连接词用when。*介词后一定不加 that ,注意介词的判断。介词 +which/whom （不用who）。关系副词=介词+which（ 2） *非限制性定语从句及有逗号的从句

8、，一定不用that （特别注意先行词为整个句子时）。*which ， that 的一些特殊用法。* 作宾语的关系代词可省略（ 3）定语从句的两个特殊句型*Is this school we visited that year?Is the school we visited that year?Is this the school we visited that year?名词性从句常考知识一、名词性从句的结构和功能总述名词性从句包括主语从句、宾语从句、表语从句、同位语从句。具有名词性功能。名词性从句主要有四种从句结构：以 that 引导的从句；以 whether/if 引导的从句；以特殊疑问
