预习案（Previewing Case）Activity 1 Read the following materials in 5 minutes.名词性从句在复合句中起名词作用的从句叫做名词性从句。
它包括主语从句、宾语从句、表语从句和同位语从句。
主语从句、表语从句、宾语从句、同位语从句，在整个句子中所起的作用，相当于一个名词。
因此，这四种从句通称为名词性从句。
1. 主语从句作句子主语的从句叫主语从句。
主语从句通常由从属连词that，whether，if和连接代词what，who，which，whatever，whoever以及连接副词how，when，where，why等词引导。
that在句中无词义，只起连接作用；连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。
例如：It is known to us how he became a writer. 我们都知道他是如何成为一名作家的。
Where the English evening will be held has not yet been announced.英语晚会将在哪里举行，还没有宣布。
有时为避免句子头重脚轻，常用形式主语it代替主语从句作形式主语放于句首，而把主语从句置于句末。
主语从句后的谓语动词一般用单数形式。
2. 宾语从句作句子宾语的从句叫宾语从句。
1）. 由连接词that引导的宾语从句由连接词that引导宾语从句时，that在句中不担任任何成分，在口语或非正式的文体中常被省去，但如从句是并列句时,第二个分句前的that不可省。
英语从句语法学习学案+经典习题(含答案)
从句讲解：从句及其特点（学案）从句是指在一个句子中充当一个成分的句子，充当什么成分就叫什么从句，如：充当宾语就叫宾语从句，充当定语成分就叫定语从句。
从以上定义中我们可以得出关于从句的一个最大特点：从句是句子。
从句的共同特点：1.从句都有自己的连接词 2.从句都是陈述语序(陈述语序就是主语在前，谓语在后)1.名词性从句在句子中起名词作用的句子叫名词从句。
名词从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。
引导名词性从句的连接词可分为三类：连接词：that, whether ,if (不充当从句的任何成分)连接代词：what, whatever, who, whoever, whom, whose, which连接副词：when, where, how, why如：That she was chosen made us very happy.宾语从句宾语从句是指在一个句子中充当宾语的句子，如：He said that he wanted to be a teacher when he grew up.宾语从句的特点：①宾语从句有自己的连接词②宾语从句用陈述语序③宾语从句的时态①宾语从句的连接词：宾语从句的连接词包括that、if/whether(是否)、特殊疑问词。
②宾语从句的语序;A.宾语从句的连接词后加陈述语序(主语在前，谓语在后),如：I want to know if he can come tomorrowB.当连接词本身又是宾语从句的主语时，后面直接加谓语动词，如：She asked me who had helped him.③宾语从句的时态，只要记住以下口诀“主现则从任，主过则从过，客观真理一般现”A.主现则从任：主句如果是一般现在时，则从句根据时间状语需要从八种时态中任选一种，如：1.He tells me he likes English very much(一般现在时)B.主过则从过：主句如果是一般过去时，则从句根据时间状语需要从四种带“过”字的时态中任选一种，带“过”字的时态分别是如：一般过去时，过去进行时，过去将来时，过去完成时。

名词性从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。

It’s the third largest state with the largest population in the country. The Indians settled in what we now know as California 15,000 years ago. California used to be ruled by Spain for over two centuries and later became a part of Mexico which had to give it to the US after its failure in the American-Mexican war. That is why today there is still a strong Spanish influence in California. It is in the Gold Rush period that a large number of immigrants from all over the world were attracted to California by the dream of becoming rich. However, what brought most of the Chinese immigrants to California is building the rail network. In the recent decades, California has become home to more people from Asia. We hold the belief that California will become more multicultural in the future.Cloning is an advanced technology with which scientists can create an exact copy of a plant or an animal.
