【常见错误展示】
下列各句均有一处错误，请改正并 分析错误的原因。 1. Light travels faster than sound is common knowledge. That that 虽无词义但引导主语从句
位于句首时不能省略。
2. Whether she’s coming or not If doesn’t matter much. if, whether 都可表示“是否”, 但 if不能引导位于主句之前的主语从 句，它可以引导位于主句之后带 有形式主语it的主语从句。

【观察总结】 通过分析上面例句，同学们可能会发 现上面第5句中的主语从句似乎比较隐蔽。 其实，这也是主语从句的一种呈现方式， 即：当一个句子主语过长时，可以用it作 形式主语，而把真正的主语或主语从句后 移至句子末尾，以保持句子的平衡。注意 观察下列例句中的划线部分：
It is not clear how the accident happened. It is not hard to understand why he did so at that time. It is a pity that you should have made such a careless mistake. It is reported that more than thirty deaths were caused in the accident.
2. That Jay Zhou will come to my city excites everybody. That Jay Zhou will 该句中主语从句是 _________________ come to my city ______________，引导词为 _____。 that 3. Whether we will travel abroad or not has not been decided. 该句中主语从句是 _________________ Whether we will __________________，引导词为 travel abroad or not whether _________。
3. It + 特殊动词 + that 从句 It seems / appears ... that ... 似乎…… It happened (to sb.) that ... （某人）碰巧…… 4. It + be + 过去分词 + 主语从句 It is said / reported / believed / suggested / known / proved that ...
将will置于trees之后。主语从句要用 陈述句语序。
5. NoWhoever matter who breaks the rule will be punished.
引导让步状语从句时二者可互换，但 引导名词性从句时只能用whoever。
6. When and where the meeting will be held still remain a question. remain
在“It is requested / ordered / suggested + that从句”中，从句要用虚拟语气，即谓 语用“should + 动词原形”，should可省
从A、B、C、D四个选项中，选出可 以填入空白处的最佳选项。 1. It is still under discussion _____ the old bus station should be replaced with a modern hotel or not. (重庆2011) A. whether B. when C. which D. where
主语从句表示单一概念时，谓语要用 单数形式。
7. What were your problems a year have ago has now become mine.
has 要改为 have。主语从句表示复数 概念时，谓语要用复数形式。
8. It was requested that everyone made (should) make a speech at the meeting.
3. That the professor said is of great What importance.
that 引导主语从句时无词义。What the professor said表示“教授所说的”。
4. Where will the trees be planted has not been decided.
不难看出，虽然上面例句中都用it作 形式主语，但句子结构却不尽相同。 现将常见的由it作形式主语的句型总 结如下： 1. It is + n. + that 从句 2. It is + adj. + that 从句，常见此类形容 词有：important, necessary, clear, certain, natural, strange, obvious, likely, impossible, possible 等。
【巩固练习】 用 what 或 that 填空。 (1) _____ he told us this morning was What just a lie. (2) _____ is important to us is enough What time. that (3) It worries my mom _____ she is beginning to get a little fat. (4) _____ we can’t get seems better than What what _____ we have.
3. 其它引导词 连接代词who, which, whom, whose有 各自的具体意义，起连接作用，同时在 从句中充当主语、宾语、表语、定语等； whoever, whatever, whichever在意义上 更为强调，常译为“无论……”；连接副 词when, where, why, how等也有各自的 意义，起连接作用，句在复合句中作句子的主语。 引导主语从句的词有从属连词that, whether, if；连接代词who, whoever, whom, what, whatever, whose, which；
连接副词when, where, how, why等。
【例句呈现】
2. whether 与 if 引导主语从句 如果主语从句置于句首，不能用if 引导，此时，需用whether。但如果用 it作形式主语，而把主语从句放在句末 时，也可以用if引导。
【巩固练习】 用 whether 或 if 填空。 whether / if (1) It doesn’t matter ___________ he will come or not. Whether (2) ________ we’ll go camping tomorrow depends on the weather. (3) It was doubtful ___________ Tom whether / if really saw Sharon. (4) ________ Tom really saw Sharon was Whether doubtful.
2. The villagers have already known

Nie Haisheng, commander of the crew, made a show of crossing his legs into a meditation (沉思) sitting posture in the air，which only a martial art (武术)master could do in the movies but was impossible for real people on earth. “Thanks to the weightless condition, we are all masters，” Wang joked.Then, she introduced the special scale on board of the orbiter, which was designed on basis of the Newton's second law of motion, or measuring the mass of an object through the net force and the acceleration.The lesson was aimed at making space more popular, as well as inspiring enthusiasm for the universe and science, according to Zhou Jianping, designer－in－chief of China's manned space program, who added that the lesson would also accumulate experience for similar larger activities.1．What's the best title for the passage?A．Chinese astronaut gives the first space lectureB．Students watch Shenzhou－Ⅹ spacecraftC．What the conditions are like in spaceD．Ordinary people act like martial art masters2．The lecture given in space is intended for ________.A．students from BeijingB．students from special areasC．students all over the countryD．students interested in the space module3．From the passage we can know that ________.A．special training makes the astronauts stay in the air like martial art mastersB．astronauts are experiencing weightless conditions when in spaceC．astronauts are showing to the students how they study and live in spaceD．the Newton's second law of motion proves to be wrong in space4．Why does astronaut Wang Yaping give the lecture in space?A．To show us what weightless conditions are like.B．To give a further explanation of weightlessness.C ．To show it is not easy to stay in space at present.D ．To make more of us interested in space science.答案与解析：本文是记叙文。
