高中英语语法：名词性从句核心考点全解+专项训练 一、知识链接（四大类名词性从句及常用引导词） · 名词性从句的定义 1. 核心概念：当一个句子由名词或代词充当的成分（如主语、宾语、表语、同位语）变成一个句子时，这个句子就称为名词性从句。 2. 具体分类（请用横线画出从句，用着重号标记引导词）： (1) 主语从句（句子的主语由从句充当） What you need is more practice. Whether they agree to the plan doesn’t matter much. It is surprising that she passed the difficult exam. (2) 宾语从句（句子的宾语由从句充当） I hope (that) you can join us tomorrow. She didn't know what she should do next. We are all worried about how he is going to handle the situation. (3) 表语从句（句子的表语由从句充当） The truth is that he never received the letter. The key point is whether we have enough funds. It seems as if it’s going to snow. (4) 同位语从句（句子的同位语由从句充当） We heard the news that our company had won the award. The fact that he didn’t say anything made everyone nervous. · 名词性从句的常见引导词 引导名词性从句的词语主要有三类： (1) 从属连词：___________(无实义，引导确定事实)；___________(表“是否”，引导未定事实)； (2) 连接代词：___________(谁/...的人)；___________(谁的)；___________(...东西)； ___________(哪一个)；___________(无论谁)；___________(无论什么)； (3) 连接副词：_________(何时)；_________(何地)；_________(为何)；_________(如何)； 二、宾语从句 1. 语序：宾语从句必须使用陈述语序，即“_________________”的顺序。 （误）Do you know where is the station?（正）Do you know where the station is? 2. 时态呼应：当主句使用一般现在时，宾语从句的时态不受限；当主句使用与过去有关的时态时，宾语从句的时态必须使用过去有关的时态（即___________，___________和___________）。 I still remember clearly how Mr. Fish ___________(emphasize) the key point last week. He mentioned that he __________(be) such a huge fan of this popular singer from a young age. When I called her, she explained that she ___________(attend) an important online conference. She promised us that she ___________(send) us a detailed report about her findings next week. My teacher told us yesterday that the sun _______(rise) in the east and _______(set) in the west. 3. 宾语从句并列情况：一般情况下，动词后的宾语从句引导词that可以省略；但如果出现了多个并列的宾语从句，从第二个宾语从句起引导词不可省略。 I know (that) you are busy right now and __________ you have no time to talk to me. 4. if与whether的使用：一般情况下，两个引导词可以替换；但特殊情况下只用whether。 (1) 与or或or not连用：I wonder whether he will come or not. (2) 在介词后：It depends on whether we have enough time. (3) 在to do前：She didn’t know whether to laugh or cry. (4) 位于句首时：Whether it is true remains a question. 三、表语从句 1. 定义：在系动词后充当表语的从句，称为表语从句。它位于系动词之后，说明主语的身份、性质、特征或状态。 The fact is that we have lost the game./The question is whether we can finish it on time. 2. 常见系动词： (1) 状态保持类：remain (仍然是), keep (保持), stay (保持), stand (处于某种状态)等 The question remains whether we can secure enough funding for the project. The agreement stands that both parties will share the profit equally. (2) 感官类：look (看起来); sound (听起来); feel (感觉起来，摸起来); smell (闻起来); taste (尝起来); seem (似乎); appear (显得，看上去)等 It sounds as if you are not entirely convinced by this plan. The situation appears that we have no other choice but to postpone the event. (3) 状态转变类：become (变成); get (变得); grow (逐渐变得); turn (变成); go (变为); come (变为); fall (陷入某种状态); prove (证明是); end up (最终...); turn out (最终...)等 The biggest challenge for him became how he could balance his work and family life. His theory proved that even the most complex problems could have a simple solution. 3. 特有引导词： It looks as if/as though it is going to rain. He was late this morning and that was because his car broke down on the way to our company. He fell ill and that was why he didn’t come to school today. 四、同位语从句 1. 定义：对一个抽象名词进行解释、说明的从句，称为同位语从句。它与被解释的名词是同位关系。 The news that our team had won made us happy./I have no idea when he will return. 2. 常见名词：fact (事实)，truth (真相)，news (消息)，reality (现实)；idea (想法)；thought (想法，念头)；belief (信念)；opinion (观点)；view (看法)；understanding (理解)；conclusion (结论)；hope (希望)；promise (承诺)；wish (愿望)；fear (恐惧)；question (问题)；problem (问题，难题)；doubt (怀疑)；answer (答案)；solution (解决方案)；suggestion (建议)；advice (建议)；demand (要求)；requirement (要求)；order (命令)；request (请求)；proposal (提议)等。 She held the firm belief that honesty is always the best policy. The boss agreed with the suggestion that we should shorten the meeting time. 3. 与定语从句的区别： 同位语从句：The news that he will come back is true. 定语从句：The news (that) he told me is true. 五、基础巩固训练：单句语法填空、标注句子中出现的名词性从句。 1. ____________ the famous actor will attend the charity event to be held next week has become the hottest topic in the town. 2.

Last Monday when class began, I asked my students how they had spent their weekend with great interest. A boy told me that he had his wisdom teeth pulled out, and then a girl said that she had gone shopping with her friends... I listened with great interest, because it seemed that everyone had had a fulfilling weekend. 篇章 2 After this terrible argument, I calmed down and rethought what happened. What surprised me most was that our quarrel broke out quickly over trivial things. I realized that I had been too selfish to see things from his perspective, and this awareness made me reflect on my behavior. The fact that he still cared about our friendship gave me a little hope. We agreed that meeting in person and having an honest conversation was the most effective way to resolve our issues. 篇章 3 I used to think that my parents were too strict and didn’t understand me. However, I realized that what they had done all along was out of love when I failed an important exam. When I was sick with a high fever, I saw how much they cared about me, staying up all night to ensure I was comfortable. What moved me most was that they still gave me firm support even though I made mistakes repeatedly. Now, I understand that their strictness was meant to guide me onto the right path and prepare me for life's challenges. 篇章 4 The idea that we could survive in the wilderness with limited supplies seemed impossible at first, especially when we got lost during a hiking trip. It was obvious that as students, we lacked rich experience in wild survival. However, we soon realized that cooperation was the key to overcoming these challenges. We were lucky that the knowledge we had gained from books and the spirit of teamwork worked well. The fact that we managed to find a stream and catch some fish gave us the strength and hope. 第 页 共 3 页 学科网（北京）股份有限公司 $
