1、高一英语备课组预习学案（5）预习目标：Learn the usage of the new words and phrases in the reading.预习自测：一、分析下列宾语从句中的连词1. I dont doubt (that) you will succeed.2. I dont know whether/if he will come tonight.3. I doubt if /whether you will keep your promise.解析：3个句子中的连词that, whether, if (是否)在名词性从句中只起连接作用，在句中不担任成分,被称为连接词。注意
2、：A. that 本身无意义，在宾语从句中可以省略，但在别的三种名词性从句中不可以省略。B. whether 和if有是否的意义，在宾语从句中二者通常可以互换。但whether 可以用于所有的四种名词性从句,而if 仅可以用于宾语从句。二、名词性从句的语序(1) 名词性从句构成有两种a. That + 陈述句 That light travels in straight lines is known to all.b. 疑问词+句子的剩余成分This is what we are looking for.(2) 疑问词引导的名词性从句要求使用陈述句语序，不能用一般疑问句语序. True or
3、False: How was he successful is still a puzzle. ( )How he was successful is still a puzzle. ( ) Could you tell me where he lives? ( )Could you tell me where does he live? ( )三、名词性从句连接词的选用(1) that 和what 的选用that 和 what 都可引导所有的名词性从句。但是，what除起连接作用外，还在名词性从句中充当成分，可作从句的主语、宾语、或表语。而that在名词性从句中不充当任何成分，只起连接作用。

6、ell.6. The question is _ he should do it.7. The doctor can hardly answer the question_ the old man will recover soon.8. I havent decided _ to go there.四、其它连接代词和副词的使用主要根据名词性从句中的具体意义，正确的选择 who, which, when, where, why, how 等连接词，这些连接词既具有疑问含义，又起连接作用，同时在从句中充当各种成分。1）_ we shall hold our sports meeting is n
7、ot decided. （我们何时举行运动会还没有决定。）2）I dont know _ broke the glass yesterday. （我不知道昨天谁打破了玻璃。）3）I have no idea _ he looks like. （我不知道他长的什么样子。）4）This is _ I left my glasses. （这就是我忘记眼镜的地方。）五、that可省略的情况：单个宾语从句中的that可省略that不可省略的情况：主语从句、表语从句、同位语从句、用it做形式宾语的宾语从句并列的宾语从句中的后几个从句的引导词that不能省略1.

9、及先行词的具体内容。定语从句中that不但起连接作用, 而且在定语从句中充当一个句子成分, 充当从句的宾语成分时可省略。同位语从句对中心词的内容作进一步的解释和说明, 表明中心词的具体内容。引导同位语从句的that在同位语从句中不做任何成分, 只起连接作用, 无具体含义, 且不可省略。1.We expressed the hope that they had expressed.2. We expressed the hope that they would come to China again.3.The information has been announced that more m
10、iddle school graduates will be admitted into university.4. The information that he revealed at the meeting is of great value.七、宾语从句的时态1. 如果主句时态是现在时或将来时,从句谓语可根据句意需要而选用任一种时态。a.他相信他的梦想总有一天会实现的。_ b.请告诉我你昨天这个时候在干什么。_2. 如果主句谓语是过去时,从句谓语动词一般用过去的某种时态,但从句表达的是客观事实、真理、自然规律等时,从句谓语通常用一般现在时。a.他告诉我他正在为考试做准备。 _b.他说他
