宾语从句一. 宾语从句的种类宾语从句是一种名词性从句，在句中作及物动词的宾语，或介词的宾语，或形容词的宾语。根据引导宾语从句的不同连词，宾语从句可分为三类。1. 由that引导的宾语从句。That只有语法作用，没有实在的意义，在口语和非正式文体中可以省略。例如：He said (that) he wanted to stay at home.他说他想呆在家里。She doesnt know (that) she is seriously ill.她并不知道她病得很严重。I am sure (that) he will succeed.我很确定他会成功。自创：我知道他正在工作：2. 由连接代词who, whom, whose, what, which和连接副词when, where, why, how引导的宾语从句。这些连接代词和连接副词在宾语从句中充当某个成分。例如：Do you know who (whom) they are waiting for?你知道他们正在等谁吗？He asked whose score was the highest.他问谁的分数是最高的。Can you tell me where the No.3 bus stop is?你能告诉我，3路车站在哪吗？I dont know why the train is late.我不知道为什么火车迟到了。自创：老师问谁的父母还没来学校？3. 由if或whether引导的宾语从句。If和whether在句中的意思是“是否”。例如：I want to know if (whether) he lives there.我想知道他是否住在那里。He asked me whether (if) I could help him.他问我，我是否给他给他提供帮助。自创：他问我小李是否在家？二. 宾语从句的语序宾语从句的语序应为陈述句的语序。例如：I hear (that) physics isnt easy.我听说物理不是那么简单。I think (that) you will like this school .我认为你将会喜欢这个学校Please tell me when well have the meeting.？请告诉我我们什么时间开会？三. 宾语从句的时态1. 如果主句的时态是一般现在时，宾语从句该用什麽时态就用什麽时态。如：I dont think (that) you are right.我不认为你是正确的。Please tell us where he is.请告诉我们他在哪Can you tell me how I can get to the railway station?你能告诉我怎样去火车站吗？2. 如果主句的时态是一般过去时，宾语从句只能用相应的过去时态。例如：He asked what time it was.他问我现在几点了。He told me that he was preparing for the sports meeting.他告诉我他正在为运动会做准备。He asked if you had written to Peter.他问你是否已经写信给彼得了。3. 如果宾语从句所陈述的是客观真理，其时态常用一般现在时。例如：Our teacher said that January is the first month of the year.我们老师说一月是每年的第一个月。We all know that the earth goes around the sun.我们都知道，地球随着太阳转。【中考范例】 1 Miss Green didnt tell us _ in 2009.
