(连接代词what在从句中作need的宾语)我们需要的是更多的水。Whether we can arrive there on time depends on the traffic. 我们是否能按时到达那里由交通情况而定。When the delayed flight will take off depends much on the weather. 延迟的航班什么时候起飞主要取决于天气状况。Why the man hadnt reported the accident sooner was never clear. 谁都不清楚那个人为什么没更早一点报告那起事故。Who the letter was from is still unknown. 这封信是谁寄的尚不清楚。三、it作形式主语当句子主语过长时，为保持句子平衡，避免头重脚轻，常把主语从句后置，而用形式主语it代替。it作形式主语时常用于以下句型：句型说明It系动词形容词主语从句常用于此句型的形容词有important，(un)likely，possible，necessary，natural，wrong等。It系动词名词主语从句常用于此句型的名词有a fact，an idea，an honour，a wonder，no wonder，a pity等。It系动词过去分词主语从句常用于此句型的过去分词有known，proved，said，decided，suggested，thought等。It不及物动词主语从句常用于此句型的动词有appear，happen，seem，occur，matter等。It is very important that a student (should) learn English well. 学生学好英语很重要。It is suggested that the meeting (should) be put off. 有人建议会议延期召开。It depends on the weather whether they are going shopping today. 他们今天是否去购物还得看天气情况。For example，it can be proved that China has more people than any other country in the world. 举例来说，中国人口比世界上其他任何国家的人口都多，这是可以得到证实的。It is no wonder that your students have made such great progress. 难怪你的学生们进步这么大。考点警示1从句的语序：在任何情况下，主语从句都用陈述语序。Whichever of you gets here first will get the prize. 你们谁第一个到达这里谁就获奖。2主谓一致(1)从句作主语时，主句的谓语一般用单数形式；但what和who引导主语从句时，有时主句谓语的数应与主句中作表语的名词保持一致。When we shall have our sports meeting has not been decided. 我们什么时候开运动会还没有确定。What they need are books. 他们需要的是书。(2)如果由and连接两个或两个以上的主语从句作主语时，谓语动词用复数；由两个或多个连接词引导一个主语从句时，谓语动词用单数。When they will start and where they will go have not been decided yet. 他们什么时候动身以及要去哪里还没定下来。How and why he came to this city is a story of struggle and success. 他如何及为什么来到这个城市是一个充满奋斗和成功的故事。3whether引导的主语从句，如果用了形式主语it，引导词whether可以换成if。如果whether从句在句首或后面有or not时，不能用if替换。Whether genetically­modified food does us harm remains to be seen. It remains to be seen whether/if genetically­modified food does us harm. 转基因食物对我们是否有害有待观察。4引导词that在主语从句中不充当句子成分，也没有含义，不可以省略；what在主语从句中可作主语、宾语、表语或者定语，有具体的含义。What caused the accident was a man lying on the ground. 引起这起事故的是一个躺在地上的男人。That she was at the entrance to the cinema then was a big surprise to me. 她当时在电影院入口处对我来说是一件让我大吃一惊的事。实战演练. 单句语法填空1Every year，_ makes the most beautiful kite will win a prize in the Kite Festival. 2It is often the case _ anything is possible for those who hang on to hope. 3Your support is important to our work. _ you can do helps. 4_we understand things has a lot to do with what we feel. 5_ Li Bai，a great Chinese poet，was born is known to the public，but some wont accept it. 6Exactly _ the potato was introduced into Europe is uncertain，but it was probably around 1565. . 完成句子1_ in his article was unknown to the general readers. 文章中他所提及的内容一般读者不知道。8The villagers have already known _ is rebuilding the bridge. 村民们已经知道我们要做的事是重建这座桥。9It matters little _，but _ is how he lives. 一个人怎么死的不太重要，但更重要的是他是如何活着的。10_ whether the newly formed committees policy can be put into practice. 新组建的委员会的政策是否会付诸实施还有待观察。11_ breaks the window will have to pay for it. 你们当中无论哪一个打破窗户都必须赔偿。基础巩固. 单句语法填空1So_ was not immediately obvious that water was to be fundamental to the development of life. 2It is not known _ he hung up on purpose. 3_ attends the party will have a chance to take a photo with the movie star. 4_ some people regard as a drawback is seen as a plus by many others. 5It doesnt interest me _ you succeed or not. 6_ the meeting will be held hasnt been decided，but perhaps next Wednesday. 7_the Internet provides the latest information is one of its greatest strengths. 8_ the couple managed to accumulate(积累) so much money in such a short time remains a mystery to the public. . 单句写作1英语作为一门国际语言正日益为人们所接受，这是事实。_2那个孩子想要的只是一个新书包。_3你能否成功取决于你努力的程度。_12我们什么时候去野餐还不知道。_13吃绿色蔬菜有助于增强体力，这一点已经得到证实。_14她在会上所说的话对公司的发展非常重要。_收获与作业完成课本同步训练课时跟踪测试二基础巩固. 单句语法填空1So_ was not immediately obvious that water was to be fundamental to the development of life. 2It is not known _ he hung up on purpose. 3_ attends the party will have a chance to take a photo with the movie star. 4_ some people regard as a drawback is seen as a plus by many others. 5It doesnt interest me _ you succeed or not. 6_ the meeting will be held hasnt been decided，but perhaps next Wednesday. 7_the Internet provides the latest information is one of its greatest strengths. 8_ the couple managed to accumulate(积累) so much money in such a short time remains a mystery to the public. . 单句写作1英语作为一门国际语言正日益为人们所接受，这是事实。_2那个孩子想要的只是一个新书包。_3你能否成功取决于你努力的程度。_12我们什么时候去野餐还不知道。_13吃绿色蔬菜有助于增强体力，这一点已经得到证实。_14她在会上所说的话对公司的发展非常重要。_收获与作业完成课本同步训练课时跟踪测试二学科网（北京）股份有限公司
