3、 sure they can tell every part of speech, especially subject、object、predictive and appositive.Step3. Explanation (Looking at the screen) (20 minutes)The usage of noun clauses:名词从句包括主语、宾语、表语和同位语等从句。它们可以由下列连词引导：从属连词 that, whether, if；连接代词 who(ever), whom, whose, what(ever), which(ever)；连接副词 when, wher
4、e, why, how, how much / many /long /often 等。 1. 主语从句：在复合句中充当主语的从句叫主语从句，上述引导词除if 外均可引起主语从句。 That he is an honest boy is known to all. What makes her different from others is her strange behaviour.Whatever was said here must be kept secret.- -3主语从句常放在句尾而用 it 作形式主语使句子更加平衡，这时口语中常省略 that, 如上面第一句改成“It is
5、known to all that he is an honest boy”更好。在下列情况下必须把主语从句放在句尾而用 it 作形式主语：1) 主句谓语是被动语态时，如：It is said that he is a good doctor.2) 主句是疑问句或感叹句时，如：Is it true that the film star will come?How wonderful it is that well visit the Great Wall tomorrow.3)主句谓语动词是 appear, turn out, happen, occur, come, strike, foll
6、ow, matter 等 It happened that she had a cold and didnt go with us that day.It turned out that I was wrong.4) 表示说话人的推测或评价，如在 it seems, it may be, it is (un)likely, it is (im)possible, it is a pity, it is a wonder 等结构中，如：It seems that this test is reliable.It is a pity that he should go without tellin
7、g anyone 5) 强调主句的表语时，如：It is a mystery to me how it all happened.It is necessary that you should tell him the truth2. 宾语从句：在复合句中作宾语的从句叫宾语从句，以上连词都可引起宾语从句。 I thought (that) you had read the book.We should learn to tell whether an element is poisonous or not.Do you know who invented this?1) 宾语从句后有宾语补足语
8、时常移至句末，而用 it 做形式宾语放在前面，如：We should make it clear that protecting the environment is everyones duty. 2 ) 宾语从句可作某些介词和某些作表语用的形容词的宾语，如：The resistance of a wire also depends upon what material it is made of.We are sure (that) it will be a success.宾语从句应注意的几个问题： 当一个动词带有两个或两个以上 that 引导的宾语从句时，第一个- -4that 可以省
9、略，但从第二个开始不可以省略。He said (that) he would spend his winter holiday in London this year and that it would be the first time he would spend his holiday alone abroad. 当宾语从句有补语时，要用形式宾语 it 代替，而将宾语从句移至补语后，同时 that 不可省略。We should make it clear that protecting the environment is everyones duty.We find it import
10、ant that one forms a good habit. 在 tell sb. that; order sb.that; remind sb.that; explain to sb. that; whisper to sb. that等结构中 that 不可省。He told me that he was going abroad next month.He whispered to me that the man in blue is a policeman. 在 be+adj.后的宾语从句中，that 可以省略。Im glad (that) Ill see all my fiend
11、s soon.Im sure (that) he will stand on our side. whether 和 if 均能引起宾语从句，但是 if 只能在动词后，在介词后要用 whether。He asked whether/if we could do him a favour.We wondered whether/if he would come or not.-Will you come tomorrow?-Sorry, I really dont know. It depends on whether it is raining (or not). 宾语从句在时态上要求与主句一
12、致（即时态呼应） ，也就是说主句为一般现在时，从句可用任何时态；如从句为一般过去时态，主句应为过去时的某种时态。当然，从句为普遍真理和自然现象者例外.He says that he lives around the corner.He says that he has been here for a long time.He says that he once worked as a cook.He says that he is expecting his fathers telephone.He said that he was learning English for the 2008
13、Beijing Olympic Games.He said that he would go abroad for further information.He said that it does not snow in winter in Australia. 在某些动词后的宾语从句中用虚拟语气，其结构为 should+动词原形，should 可以省略。这些常用动词是：一个坚决要求 insist; 两个命令 order, command; 三个建议 suggest, advise, propose；四个要求 ask, demand, request, require- -5注意：insist
14、 有两个意思“坚决要求”和“坚持认为” ，前者用虚拟语气，而后者用陈述语气（实际时态） ；同样 suggest 也有两个意思“建议”和“表明”或“暗示” ，当“建议”讲时用虚拟语气，否则用陈述语气（实际时态） 。如：He insisted that he should go to the front.(虚拟语气)He insisted that Tom was honest and hardworking.(陈述语气)She suggested that she should answer the phone immediately.(虚拟语气)The smile on her face su
15、ggested that he was satisfied with the result.(陈述语气)述其他动上词后一律用 should+动词原形如 They requested that an immediate answer should be given.He ordered that the troops (should) start at once.3. 表语从句：由 that, as if, wh-等引起的作表语的从句叫做表语从句。 The fact remains that we are behind some developed countries.It seems /app
16、ears as if the problem has been settled.Thats what we should do.4. 同位语从句：idea,fact,rumour,message,news,hope,belief,thought,doubt,proof,evid-ence，promise, probability 等名词后出现的 that 或 wh-引导的从句作同位语，人们称之为同位语从句，同为语从句对所修饰得词起解释说明的作用。They expressed the hope that they would visit China again.There is no doubt
