Rule2: whether和if都有"______"之意，引导名词性从句。但在以下情况下只能用whether，不能用if：①引导______从句；②引导______从句；③从句位于句首；④后接______；⑤与______连用。 　 ⑥ What we need is more time. ⑦ Who will be our new manager has not been decided. ⑧ Which book you choose is up to you.

It作形式主语的常见句型： ① It + be + 形容词 + that从句（It is certain that...） ② It + be + 名词 + that从句（It is a fact that...） ③ It + be + 过去分词 + that从句（It is said that...） ④ It + 不及物动词 + that从句（It seems that...） 　 2. It作形式宾语的常见结构： 主语 + 谓语 + it + 宾语补足语 + that/wh-从句（I think it important that we should learn English well.） 　 Exercise: 1. ______ is known to all that China is a country with a long history. 2. I think ______ necessary that we should take exercise every day. 3. ______ happened that he was out when I called. 4. We found ______ strange that he didn't say a word at the meeting. 5. ______ is reported that the number of tourists has increased by 20%. 　 Step 5: 名词性从句中的虚拟语气 1. 在表示建议、命令、要求、坚持等动词后的宾语从句中，谓语动词用"(should+)动词原形"。 常见动词：suggest, advise, recommend, demand, require, request, insist, order, command, desire等。 例：The doctor suggested that he (should) take a good rest. 　 2. 在It is + 形容词/名词 + that从句句型中，若形容词为important, necessary, essential, natural, strange等，从句谓语用"(should+)动词原形"。 例：It is necessary that we (should) learn from each other. 　 3. 在suggestion, proposal, order, request, advice等名词后的表语从句和同位语从句中，谓语动词用"(should+)动词原形"。 例：His suggestion is that we (should) put off the meeting. 　 Exercise: 1.

The problem that we are facing is serious. （________） 5. The question whether we should go has not been decided. （________） 　 Step 7: 宾语从句的特殊用法 1. 否定转移：当主句谓语为think, believe, suppose, expect, imagine等表示"认为、相信、猜想"的动词，主语为第一人称且为一般现在时时，从句的否定要转移到主句上。 例：I don't think he is right.（我认为他不对。） 　 2. 时态呼应：当主句为过去时态时，宾语从句要用相应的过去时态（一般过去时、过去进行时、过去将来时、过去完成时）。但如果从句表示的是客观真理、自然现象，则仍用一般现在时。 例：He said that the earth goes around the sun.（客观真理，时态不变） 　 3. 疑问词+不定式结构：宾语从句可以简化为"疑问词+不定式"结构。 例：I don't know what I should do. = I don't know what to do. 　 Exercise: 1. 我认为他不会来。（翻译，注意否定转移） ________________________________________________ 2. He said that he ______ (go) to Beijing the next day. 3. The teacher told us that light ______ (travel) faster than sound. 4. She asked me where she could buy the book.（改为简单句） ________________________________________________ 　 Step 8: what与that的区别 ① That he won the first prize surprised us all. ② What he said at the meeting is important. 　 区别：①that在从句中______（充当/不充当）成分，______（有/没有）实际意义；②what在从句中______（充当/不充当）成分（主语、宾语或表语），意为"______"，相当于"the thing(s) that"；③判断方法：将从句单独拿出来，看是否缺少主语、宾语或表语，缺少则用what，不缺则用that。 　 Exercise: 用that或what填空 1. ______ he needs is a good rest. 2. ______ he will come is certain. 3. I don't know ______ he wants. 4. The truth is ______ he has lied to us. 5. ______ matters most is health. 6. It is a fact ______ English is widely used. 　 Step 9: 名词性从句的语序 名词性从句一律用______语序（陈述语序/疑问语序），即"连接词+主语+谓语"的顺序。 例：I don't know where he lives.（不能说where does he live） 　 Exercise: 改正下列句子中的错误 1. I don't know where does he work. ________________________________________________ 2. What did he say at the meeting is unknown. ________________________________________________ 3. Can you tell me how can I get to the station? ________________________________________________ 4.
