from the pump so much that she had it delivered to her house every day． 5．(教材P3)The truth was that the water from the Broad Street pump had been infected by waste． 6．That's why we've given you the letter． Ⅱ．根据以上例句填空。 1．句1中系动词became后接 形容词 作表语；句2、3、4、5中作表语的是 从句 。 2．句2、3、4、5中的连接词 that 在句中起连接作用，没有含义。 3．句6中引导 表语从句 的连词有一定的含义，意为“ 为什么 ”。 在主从复合句中充当表语的从句称为表语从句。它常位于系动词之后，用来说明主语是什么或怎么样。 一、表语从句的引导词 (一)从属连词that/whether引导的表语从句 that和whether在表语从句中不作任何成分，不可省略，that无实义，但whether仍保留“是否”的意义。 ►My suggestion is that we should tell him． 我的建议是我们应该告诉他。 ►The question remains whether they will be able to help us．问题是他们是否会帮助我们。 [提示] if不能引导表语从句。 [即时训练1]——用适当的连接词填空 (1)(2024·1月浙江)The most obvious advantage of online learning is that you can study anywhere and anytime． (2)(2023·1月浙江)The only thing I don't like is that my mom wants to know every part of my life． (3)What he wants to know is whether we can finish our work by tomorrow morning． (二)连接代词引导的表语从句 连接代词what(ever), which(ever), who(ever), whom(ever), whose等引导表语从句时，本身有意义，除了在句中起连接作用外，还在从句中充当主语、宾语、表语、定语等成分。 ►The problem is who should be responsible for the task．问题是谁应该为这项工作负责。 ►Motivation is what you need most to do a good job． 动机是你做好工作最需要的东西。 ►What puzzled me was which book I should choose．使我困惑不解的是我该选哪本书。 [即时训练2]——用适当的连接词填空 (1)This is what my father has taught me—to always face difficulties and hope for the best． (2)The problem is who is really fit for the hard job． (3)The problem is who can take the place of Jim． (三)连接副词引导的表语从句 连接副词when, where, why, how等引导表语从句时，除在句中起连接作用外，在从句中往往作状语(时间、地点、原因、方式)。 ►The last time we had great fun was when we were visiting the Water Park． 我们上一次玩得很开心是游览水上公园的时候。 ►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堵车，那就是她上课迟到的原因。 [即时训练3]——用适当的连接词填空 (1)By boat is the only way to get here, which is how we arrived． (2)Jack fell ill suddenly．This was why he didn't take part in the sports meeting． (3)Go and get your coat．It's where you left it． (四)其他引导词 as if/as though引导的表语从句常置于系动词be, look, seem, sound, become等后面，从句表示的情况发生的可能性比较小时，常用虚拟语气。because引导的表语从句常见于“This/That/It is/was because…”句型中。 ►It sounds as if someone is knocking at the door．听起来好像有人在敲门。 ►The house was in such a mess—it looked as though a bomb had dropped on it． 屋子一片狼藉，就好像有炸弹落在这里过。 ►She didn't pass the exam．That's because she didn't go over his lessons． 她没有通过考试，那是因为她没有复习。 (五)注意事项 1．why和because引导表语从句的区别 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。 2．reason作主语时的表语从句 主语为名词reason时，表语从句中的连接词要用that，而不用because。 ►The reason for such a serious accident is that the driver was too careless and drank too much．这么严重的交通事故是司机太粗心，喝了太多酒造成的。 [即时训练4]——用适当的连接词填空/补全句子 (1)From space, the earth looks blue．This is because about seventy-one percent of its surface is covered by water．
