Section Ⅱ　Learning About Language [对应学生用书P8] 表语从句 一、表语从句的概念 在主从复合句中充当表语的从句，叫作表语从句。它常位于系动词之后，用来说明主语的身份或特征。 The good news is that we Chinese are warm and friendly，so you needn't worry too much about Chinese customs. (应用文之推荐信) 好消息是我们中国人热情友好，所以你不必太担心中国的习俗。 The question is whether it's worth trying. 问题是值不值得一试。 The last time we had great fun was when we were visiting the Water Park.我们最后一次开心地游玩是我们参观水上公园的时候。 [即时训练1]　用适当的连接词填空 ①It is important for us to master some basic living skills to prepare us for our future life.That is why I learned how to cook during the May Day holiday.(2023·全国乙卷，书面表达) ②If most of their customers are happy to buy larger quantities，that's what they'll promote.(2024·浙江卷1月，语法填空) ③He failed the exam again. The reason was that he was too careless. 二、表语从句的引导词 The trouble is that she doesn't know how to adapt to the new school. 麻烦的是她不知道如何适应新学校。 The question is whether you can do the work well.问题是你能否做好这项工作。 Every time I listen to the music，it feels as if a picture of a river is spreading before me. 每当我听这首音乐的时候，感觉就像一条河的画面在我面前铺开。 The most important is who will be in charge of the evening party. 最重要的是谁将负责这次晚会。 Sara was caught in a traffic jam this morning. That is why she was late for school. 萨拉今天早上遇到了交通堵塞，那就是她上课迟到的原因。 [即时训练2]　用适当的连接词填空 ①At that moment，what I really understood was how kind he was.(2024·新课标Ⅰ卷，读后续写) ②The truth is that we are lucky enough to have clean water whenever we want. ③You are saying that everyone has already had equal rights，and this is where I disagree. 三、注意事项 1．that与what的区别 that引导表语从句时，是从属连词，在从句中不作成分；what是连接代词，引导表语从句时，在从句中作主语、宾语、表语或定语。 That was what she did this morning on her way to school. 那就是她今天早晨在去学校的路上做过的事。 2．because与why的区别 because引导表语从句时强调原因，why引导表语从句时强调结果。 She often comes late. That's because she has a baby to take care of. 她经常迟到。那是因为她有一个婴儿要照顾。 He always finds fault with me and that's why I get angry with him. 他总是找我的茬。那就是我生他气的原因。 名词reason作主语时，后面的表语从句表示原因时要用that引导，而不用because。 The reason why he was late is that it was raining hard.他来晚了是因为天正在下大雨。 [即时训练3]　用that/what/because/why填空 ①The most pleasant thing of the rainy season is that one can be entirely free from dust.②The question is what we can do to solve this problem once and for all. ③I drove to Zhuhai for the air show last week.This is why I had a few days off. ④My face was red.This was because I was anxious.(2024·新课标Ⅰ卷，读后续写) 3．虚拟语气用于表语从句 (1)在表示建议、劝告、命令等含义的名词后的表语从句中，谓语动词用“should＋动词原形”，should可以省略。 My suggestion is that we(should) have a discussion about this matter instead of just laying it aside.我的建议是我们应当讨论一下这件事，而不应该只是把它放在一边。 (2)as if/as though引导的表语从句常用虚拟语气。用一般过去时表示现在，过去进行时表示现在进行，过去完成时表示过去，could/would/might＋动词原形表示将来。 It looks as if he were ten years younger today. 今天他看起来好像年轻了10岁。 [即时训练4]　用所给词的适当形式填空 ①The doctor's advice is that we(should) take (take) more exercise. ②My proposal is that you(should) arrange (arrange) for your assistant to deal with this matter. ③My suggestion is that you(should) get(get) yourself involved in music activities，such as singing and composing.(应用文之建议信) [对应学生用书P10] Ⅰ.单句语法填空 1．(2025·全国二卷)People get in their minds an idea of what teachers do，but that's not really what it is here. 2．For me，the most important is that I am inspired to become a doctor in the future. 3．You must need support now，which is why I'm writing to provide some advice for you. 4．It doesn't matter where you spend your holiday; what matters is how you spend it. 5．The most exciting moment was when I was given the first prize. 6．What I want to say is that exercise is as useful and important as your study.
