从句 从句按其在主句中的句法功能可分为三类: 即名词性从句、形容词性从句(即定语从句)和副词性从句(即状语从句)。 引导从句的词称作关联句. 一、名词性从句 引导这些名词性从句的关联词包括: 从属连词that, if, whether; 连接代词 who,whoever,whom,whomever,which,whichever,what,whatever,wh ose; 连接副词where, when, why, how。 其中, 从属连词只起连接作用, 在从句中不充当任何句法成分, 而连接代词和连接副词既起连接作用, 在从句中又充当一定的成分. That Owen should have married his cousin is not at all surprising. The fact is that he didn't go to the dinner party. I don't know if he will attend the meeting. Have you heard the news that Mary is going to marry Tom? 你听说玛丽要和汤姆结婚的消息了吗?(that引导同位语从句) [提示]
1. 在含有主语从句的复合句中, 为保持句子平衡, 常用it作形式主语,而将真正的主语从句置于句末. It's well-known that water is indispensable to life.(形式主语) 2. 为保持句子平衡, that引导的宾语从句也常用it代替, 而将真正的宾语从句置于主句句末。这常常出现在主句有形容词或分词作宾语补足语的情况下。 He made it quite clear that he preferred to live here. 3. 从属连词whether和if都作“是否…”解, 但if不可引导主语从句和表语 从句。whether可与or(not)连用, 而if不可以。 I don't know whether (if) she is at home. Whether she comes or not makes no difference. 4. that和what引导名词性从句的区别: that在从句中不充当成分,而what在从句中充当一定的成分, 如主语、表语、宾语等。that可省略, what则不可省。 He always means what he says. She suggested (that) he do it at once. 5. 同位语从句大多由从属连词that引导, 常跟在下列名词后面, 如fact, idea, opinion, news, hope, belief等, that不可省。同位语从句一般用来解释说明这些名词的具体含义和内容。 We are familiar with the idea that all matter consists of atoms. The news that we are invited to the conference is very encouraging.
考点30 地点状语从句 高考频度：★★★★★ 一、where引导的地点状语从句 1.从属连词where表示＂在（或到）……的地方＂。 Where there is a will, there is a way. 有志者事竟成。 Put it where you found it. 把它放在原来的地方。 2. where 在地点状语从句中，除指地点外，还可指处境等。 He said he was happy where he was. 他说他对自己的处境很满意。 It’s your fault that she is where she is. 她今天落到这个地步都怪你。 3. 有时地点状语从句中的某些词可以省略。 Fill in the blanks with the given phrases. Change the form where necessary. 用所给的短语填空，必要的地方可以改变其形式。 Avoid structure of this kind where possible. 只要可能，就要避免这种结构。 4. Half an hour later, Lucy still couldn’t get a taxi _______ the bus had dropped her. A. until B. when C. although D. where 【答案】D 【名师点睛】本题考查定语从句。定语从句是高考重点考查知识之一，分析定语从句需要牢牢抓住两点：第一、找准先行词。第二、看先行词在从句中所作的成分。抓住这两点，再根据句意，从而能够判断出正确的关系词。 2.______ he once felt like giving up, he now has the determination to push further and keep on going.
