[自我归纳] (1)所有例句中的黑体部分都位于系动词be后，作表语，故都是表语从句，这些表语从句在词性上相当于一个名词。 (2)例1由从属连词 that 引导；例2由连接代词 who 引导；例3由从属连词 whether 引导；例4由连接副词 why 引导；例5由连接代词 what 引导。 表语从句放在连系动词之后，充当复合句中的表语。表语从句就是指一个句子作为表语，说明主语是什么或者怎么样。 一般结构为“主语＋系动词＋表语从句”。可接表语从句的连系动词有be，look，remain，seem等。 1．从属连词that引导的表语从句 从属连词that的用法：①无意义　②不充当成分 ③不可省略 The reason for his absence is that he hasn't been informed. 他缺席的原因是他没接到通知。 My suggestion is that we should tell him. 我的建议是我们应该告诉他。 2．从属连词 whether 引导的表语从句 The point is whether we should lend him the money. 关键在于我们是否应该借钱给他。 [名师指津]　if 不能引导表语从句。 3．连接代词和连接副词引导的表语从句 The problem is who is really fit for the hard job. 问题是谁才真正适合做这份艰苦的工作。 This is what I am interested in. 这就是我所感兴趣的。 That's where I first met her. 那就是我第一次遇见她的地方。 4．because，as if/though 等引导的表语从句 It's just because he doesn't know her. 这仅仅是因为他不认识她。 Now it seems as though she had known Millie for years. 现在好像她认识米莉已有好多年了似的。 It sounds as if someone is knocking at the door. 听起来好像有人在敲门。 5．why和because引导的表语从句的区别 That's why... 意为“那是……的原因”，强调结果 That's because... 意为“那是因为……”，强调原因 I didn't phone her，and that's why she got angry with me.(强调“没打电话”这一结果) 我没有给她打电话。那就是她对我生气的原因。 I didn't phone her，and that's because I got angry with her.(强调“生气”这一原因) 我没有给她打电话。那是因为我生她的气了。 [名师指津]　reason 作主语时，后面的表语从句表示原因时要用that引导，不宜用because。 6．表语从句中的虚拟语气 在表语从句中，表示间接的命令、要求、请求、建议、决定等，主句中的主语通常是advice，suggestion，proposal，request，order，idea等，从句谓语形式是“should＋动词原形(should可以省略)”。 My advice is that you (should) practise speaking English as often as possible. 我的建议是你应该尽可能经常地练习说英语。 Usage要点拾遗 sort out 理顺，整理；把……安排好；解决；从……区分出来；分类 [教材P34]　However，his work proved difficult，because sorting out all the available resources and checking facts of historical materials required painstaking efforts. 然而，他的工作是困难的，因为整理所有可用的资源和核实历史资料的事实需要艰辛的努力。 (1)sort out...from...把……从……中挑选出来/辨别出来 sort sth.(into sth.)把……分类 (2)sort of有几分；有点(作副词修饰形容词和动词) all sorts of...各种各样的…… a sort of某种的，一种 (1)—You look uneasy；is there anything wrong? —I feel sort of cold. ——你看上去不舒服，有什么事吗？ ——我感到有点冷。 (2)Please sort out these books in the alphabetical order. 请把这些书按字母顺序整理一下。 [即学即用]　单句语法填空 ①After supper，we would play all sorts of card games in the sitting room. ②She sort of pretends that she doesn't really care. 写出下列句中sort out的汉语意思 ③My father helped sort out a dispute today.解决 ④Please sort out what you want and throw away the rest.挑选出 ⑤The child was sorting out the bricks into different colors.把……分类 1．He got caught in the heavy traffic.That was why he was late. 2．Energy is what makes things work. 3．We didn't set out；it was because we wanted to wait until our mother came back. 4．The most pleasant thing of the rainy season is that one can be entirely free from dust. 5．A ship in harbor is safe，but that's not what ships are built for. 6．The trouble is that I can't find my way. 7．What he wants to know is whether we can finish our work by tomorrow morning. 8．The reason why I was sad was that he didn't understand me. 9．That is what we are looking forward to. 10．This is where the waters of Amazon flow out into the sea. 1．Jane is no longer what she was ten years ago. 简再也不是十年前的那个样子了。 2．I read about your reform of the school English newspaper，and that's why I'm writing to voice my opinion． 我获悉了你对英语校报的改革方案，那就是为什么我写信发表我自己观点的原因。 3．The question is whether they will be able to help us． 问题是他们是否能帮我们。 4．That was because he didn't understand me． 那是因为他没有理解我。 5．The fact is that our team has won the game． 事实就是我们队已经赢得了比赛。 学科网（北京）股份有限公司 $$
