Section Ⅳ　Using language 名词性从句 语法串烧 我的发现 　　What① worries my classmate Mary a lot these days is that② she puts on too much weight and she is frequently ill.She has some doubts whether③ she eats too much fast food high in fat or sugar.Also，with the College Entrance Examination approaching，she becomes more stressful and she can’t sleep well these days.Maybe this is why④ she becomes fatter these days，she thinks.How⑤ she becomes slimmer and healthier has been her main task.So she wants to consult some experts and gain some instructions.But where she could get better suggestions and who⑥ will give her better advice also puzzle her.It is her parents’ suggestion that⑦ she should consult Professor Wang in Zhongshan Hospital.Professor Wang suggests that⑧ she keep a balanced diet first.She should eat vegetables and fruit high in fiber，vitamin and protein.What’s more，if she wants to lose weight，she had better take regular exercise more than half an hour a day.Mary asked Professor Wang when⑨ she should take exercise.Professor Wang advised her to take exercise at 5 o’clock in the afternoon.That is because⑩ she will have more time to do sports.It is with the help of Professor Wang that Mary has become much healthier now. ①⑤⑥为主语从句。 ②④⑩为表语从句。 ⑧⑨为宾语从句。 ③⑦为同位语从句。 ①⑥为连接代词，可以在从句中作主语和宾语。 ④⑤⑨为连接副词，在从句中作状语。 ②③⑦⑧为连接词，在从句中不作句子成分，that没有任何意义，whether有“是否”之意。 一、名词性从句概述 在复合句中起名词作用的从句叫名词性从句，包括主语从句、表语从句、宾语从句和同位语从句。 二、引导名词性从句的连接词 连接词：that，whether/if 连接代词：what，which，who，whom，whose，whatever，whichever，whoever，whomever 连接副词：how，why，when，where，however，whenever，wherever 学生用书第141页 三、名词性从句的基本用法 1．连接词that，whether/if的用法 that引导的名词性从句 that引导名词性从句时本身无意义，只起连接作用，也不在句中作任何成分。它引导的名词性从句结构和意义都完整，往往用于陈述事实。引导主语从句、表语从句和同位语从句时，that不能省略。引导宾语从句时，在口语和非正式文体中，that有时可省略。 that引导主语从句时可用it作形式主语的四大句式：1.It＋be＋形容词＋that从句；2.It＋be＋名词(短语)＋that从句；3.It＋be＋过去分词＋that从句；4.It＋特殊动词或短语＋that从句。 whether与if引导的名词性从句 用whether或if均可的情况 whether可引导各种名词性从句。引导大部分动词后的宾语从句时，两者均可。 it作形式主语，且主语从句在句末时，两者均可引导主语从句。 用whether而不用if的情况 1.主语从句置于句首时；2.引导表语从句和同位语从句时；3.引导介词的宾语从句时；4.引导词与or not连用时；5.引导词后接to do时；6.有些动词如leave，put，discuss，decide等后的宾语从句时。 It is decided that the meeting has been put off till next Monday.(主语从句，不缺成分和语义) 已经决定会议推迟到下周一。 He gave us a suggestion that we should practise speaking English in class.(同位语从句，不缺成分和语义) 他建议我们在课堂上练习说英语。 Tim didn’t know whether/if he could pass the exam. 蒂姆不知道他能否通过考试。 It depends on whether you can do the work well. 那取决于你是否能做好这项工作。 [名师点津]　that引导及物动词后的宾语从句时，可以省略。 2．连接代词和连接副词引导的名词性从句 引导词类别 常见引导词 功能 连接代词 what，which，who，whose，whom，whatever，whichever，whoever，whomever 有词义；在从句中担任成分，作主语、表语、宾语或定语等 连接副词 how，when，where，why，however，whenever，wherever 有词义；在从句中担任成分，作状语 What was most important to her，she told me，was her family.(主语从句，what在从句中作主语) 她告诉我，对她来说最重要的是她的家人。 The employers often give the job to whoever they believe has work experience with a strong sense of duty.(宾语从句，whoever在从句中作主语) 雇主们经常会把工作给他们认为有工作经验并且有强烈责任感的人。 The problem is where we should stay.(表语从句，缺语义，连接词在从句中作状语) 问题是我们应该待在哪里。 They couldn’t understand why I refused it.(宾语从句，缺语义，连接词在从句中作状语) 他们不明白我为什么拒绝这件事。 [名师点津]　单个的主语从句作主语时，谓语动词用单数形式。如果是两个或两个以上的主语从句作主语，谓语动词则用复数形式。 Where and when he was born has not been found. 他出生的地点和时间还没有找到。 学生用书第142页 When the person was murdered and why he was murdered are still unknown. 这个人什么时候被谋杀，为什么被谋杀，现在还不清楚。 ◎巧学活用1——用恰当的连接词填空 (1)The fact that he hadn’t said anything at the meeting surprised us.

(6)She always thinks of how she can work well. 四 、名词性从句的疑难点 1．that与what引导名词性从句的区别 that在从句中不充当句子成分，也没有含义；what可以在从句中作主语、表语、宾语和定语，意思是“什么，什么……的事情，什么样的”。 Our teacher made a request that we (should) be well prepared for the exam. 老师要求我们为考试做好充分准备。 We had to write a paper on how we plan to apply what we would learn in class to our future professions. 我们必须写一篇论文，内容是我们打算如何将课堂上学到的知识应用到未来的职业中。 2．wh-与wh-ever引导名词性从句的区别 连接词what，which，who分别表示“……的东西或事情”、“哪一个”、“谁”，表示疑问含义；而whatever，whichever，whoever分别相当于anything that，any...that，anyone who，意为“无论……”，强调一切情况。 What you choose to wear should be clean. 你选择穿的衣服应该是干净的。 Whatever you choose to wear should be clean. 无论你选择穿什么，都应该是干净的。 3．表示“要求，建议，命令，坚持”的词后跟名词性从句时，从句中的谓语动词用“should＋do”，其中should可以省略 The boss ordered that the task (should) be completed by noon.(宾语从句) 老板命令(我们)在中午之前完成任务。 The doctor’s advice is that I (should) rest more and drink more.(表语从句) 医生建议我多休息、多喝水。 ◎巧学活用2——完成句子 (1)你主张把钱用于建造一座幼儿园是极好的。 Your proposal that the money (should) be used to build a nursery school is admirable.(同位语从句) (2)那就是为什么我请了三天假。 That was why I asked for three days’ leave. (3)任何违反规则的人都必须受到惩罚。 Whoever breaks the rule must be punished. (4)他会告诉我们，我们不在的期间他出了什么事。 He will tell us what happened to him during our absence. 学科网（北京）股份有限公司 $
