专题四 第 2 讲 名词性从句 一、核心知识点梳理 名词性从句在句中相当于名词，可充当主语、宾语、表语、同位语，分为主语从句、宾语从句、表语从句、同位语从句四类。 （一）四类名词性从句判定 宾语从句：置于及物动词、形容词后 主语从句：位于谓语动词前；可使用 it 作形式主语 表语从句：位于 be 动词等系动词后 同位语从句：跟在抽象名词后，解释名词完整含义 （二）引导词分类及用法 1.从属连词（不作从句成分，无实义 / 有限词义） that：无词义，不充当成分 whether/if：表 “是否”，不作成分 because、as if/though：分别表示 “因为”“好像” 连接代词（从句内充当主 / 宾 / 表 / 定语） who(ever)、whom(ever)、what(ever)、whose、which(ever) 连接副词（从句内作状语） when(ever)、where、wherever、why、how(ever) 2. 语序规则：名词性从句统一使用陈述语序 疑问句中包含名词性从句时，从句内部不能采用疑问倒装结构。 例： Do you know where will the party be held？（错误） Do you know where the party will be held？（正确） 3. 时态搭配规则 （1）若主句谓语为现在时态（一般现在时、现在进行时、现在完成时），从句可根据动作发生的实际时间灵活选用对应时态。 ① It annoys me that he broke my favourite vase. 他打碎了我心爱的花瓶，这让我十分生气。 ② Do you know when and where he bought the book？ 你清楚他是何时、何地买下这本书的吗？ ③ I have heard that our teacher will come back tomorrow. 我听说老师明天就会回来。 （2）若主句谓语为过去时态，宾语从句通常改用对应的过去类时态；但如果从句内容是客观真理、自然常识，则仍使用一般现在时。 ① I asked her if she would allow me to interview her，and she readily agreed. 我询问她是否同意我进行采访，她爽快地答应了。 ② My teacher said that the sun rises in the east and sets in the west. 老师告诉我们，太阳东升西落。（客观真理，时态不变） 4. that 与 what 的用法区分 that 属于从属连词，引导名词性从句时无实际词义，也不在从句中充当任何句子成分； what 属于连接代词，本身带有含义，必须在从句内充当主语、宾语或表语。 ① I believe that I will succeed if I study hard. 我坚信只要努力学习，我就能够成功。 ② I believe what he said because he is an honest man. 我相信他所说的话，因为他为人诚实。 5. whether 与 if 的选用规则 （1）两者均可通用的场景 ① 引导绝大多数实义动词后接的宾语从句； ② it 作形式主语、主语从句置于句末时，二者都可引导主语从句。 （2）只能用 whether、不可使用 if 的场景 ① 主语从句直接置于句首； ② 引导表语从句、同位语从句； ③ 置于介词之后引导宾语从句； ④ 与 or not 搭配连用； ⑤ 后接不定式 to do 结构； ⑥ discuss、decide 等动词后引出宾语从句。 6. wh 疑问词与 wh-ever 类连接词区别 （1）what、who、which 带有疑问含义，分别表示 “什么”“谁”“哪一个”。 例：Do you know who broke the window? 你知道是谁打碎了窗户吗？ （2）whatever、whoever、whichever 无疑问语气，含义为 “所有…… 的事物”“任何…… 的人”“任意一类事物”，在从句中承担句子成分，等价于 anything that、anyone who。 例：We have been prepared to do whatever it takes to save her life. = We have been prepared to do anything that it takes to save her life. 她对我们至关重要，我们愿意付出一切代价挽救她的生命。 7. that 不能省略的几种情况 （1）that 引导的主语从句放置句首、引导表语从句、引导同位语从句，或是 it 作形式宾语时引导真正宾语从句，that 均不可省略； （2）主句谓语后并列多个宾语从句时，仅第一个从句开头的 that 能够省略，后续从句前的 that 必须保留。 例：She said (that) her ambition was to enter a key university，that she would study hard to make her dream come true，and that she would live up to her parents’ expectations. 她说她的目标是考入重点大学，会刻苦学习圆梦，也不会辜负父母的期许。 8. 同位语从句使用场景 同位语从句紧跟表抽象概念、思想类名词，用来完整解释该名词的具体内容。 常搭配抽象名词：news，idea，fact，promise，conclusion，theory，question，doubt，thought，hope，message，suggestion，word（消息），possibility，decision。 例：At first many people were astonished at the conclusion that the earth was not the centre of the universe. 起初，很多人都难以接受地球并非宇宙中心这一结论。 9. why 与 because 引导表语从句的差异 because 侧重解释事情发生的根源（强调原因）；why 侧重引出某一结果（强调后果）。 ① I had a cold. That was why I didn’t attend school. 我感冒了，所以没能去上学。 ② I didn’t attend school. That was because I had a cold. 我没来上学，是因为我得了感冒。 补充两点固定句式要求： （1）句子主语为 the reason 时，后面的表语从句只能用 that 引导，不能用 because。 例：The reason why she was ill was that she had eaten bad meat. 她生病的根源是吃了变质的肉类。 （2）若 why 引导从句作整个句子的主语，后续表语从句需用 that 衔接。 例：Why we decided to put off the match was that the weather was too terrible. 我们决定推迟比赛，是因为天气状况十分恶劣。 10. as if/though 引导表语从句 as if/though 多用于 look、seem、sound、be 等系动词之后，从句既可以使用陈述语气描述真实情况，也能用虚拟语气描述与现实不符的假想。 ① It sounds as if somebody is knocking at the door. 听声响，好像有人在敲门。（陈述语气，大概率为事实） ② She treats him as if he were a stranger. 她对待他，仿佛对方只是陌生人。（虚拟语气，与事实不符） 11. 同位语从句与定语从句核心区分 同位语从句功能是解释名词的完整内涵；定语从句功能是限定、描绘先行名词的范围与特征。 连接词 that 的作用完全不同： 同位语从句中的 that 仅起连接作用，无词义、不作从句成分，不可省略； 定语从句中的 that 是关系代词，指代前面的先行词，在从句中充当主语、宾语或表语，作宾语时可省略。 ① I had no idea that Brisbane has so many people! （同位语从句，that 不可省略） 我之前完全不知道布里斯班人口这么多。 ② The idea (that) he put forward at the meeting is very reasonable. （定语从句，that 在从句作宾语，可省略） 他在会议上提出的观点十分合理。 二、小试牛刀1 1．People wonder ____________ Qizai
