(宾语从句)
Some people believe that colours can influence our moods.(宾语从句)
新课讲解
宾语从句
宾语从句是指一个句子充当宾语，在主句与从句之间有一个引导词。
eg. We know that Mr Green teaches English.
She asked if these answers were right.
宾语从句三要素
引导词（连接词）
语 序
时 态
新课讲解
不同引导词引导的宾语从句
由that引导的宾语从句
由连接代词 who,whom,whose,which，
what 和连接副词 where,how,why,when
（即疑问词）引导的宾语从句
由whether, if 引导的宾语从句
新课讲解
连词that引导宾语从句，它本身无意义，在口语或非正式文体中常省略。
e.g. He says (that) he is a Young Pioneer.
他说他是个少先队员。
一、引导词本身的省略与不省略
1. 一般可以省略
that 引导的宾语从句
2. 不可以省略
从句的主语是that时，that不省略。
e.g. We know that that is an interesting story．
我们知道那是一个有趣的故事。
新课讲解
二、何时使用that引导的宾语从句
that引导的宾语从句，表示陈述一件事，即由陈述句转化而来。
1. 主句的谓语动词是 think, hear, hope, wish, remember, forget, know, say, guess等时，常接that引导的宾语从句。
e.g. I hope (that) he will be fine soon．
我希望他很快好起来。
2. 主句由“连系动词＋形容词”构成的“系表”结构，常接that引导的宾语从句。这类形容词多表示感情，如 happy, glad, sorry, sad, sure, afraid, certain 等等。
e.g. I’m afraid (that) he can’t come．
恐怕他不能来了。
新课讲解
三、that引导的宾语从句相关的内容
1. 语序
不论什么情况下，宾语从句都要用陈述语序，即“主语＋谓语＋其它”。
e.g. Do you think (that) the radio is too noisy 你认为收音机太吵吗？
2. 时态
When the main clause uses the simple present tense or future tense, the object clause still uses the original tense.
宾语从句，主句用一般现在时，从句可以用符合句意要求的任一时态。
e.g. He says (that) they have returned already. 他说他们已经回来了。
新课讲解
一般现在时
一般过去时
现在进行时
过去进行时
一般过去时
过去完成时
现在完成时
过去完成时
一般将来时
过去将来时
When the main clause uses the simple past tense, the tense in the object clause should be changed into the corresponding past tense.
如果主句用一般过去时,从句要用过去时态的某种形式（一般过去时,过去进行时,过去将来时,过去完成时）。
e.g. I saw that she was dancing.
He said that he had seen it .
He said that his father would come back.
新课讲解
[注]如果从句表达的是客观事实、真理、自然现象、名言、警句、格言、谚语等等，尽管主句用一般过去时，从句也要用一般现在时。
e.g. Our teacher told us that light travels faster than sound.
我们老师告诉我们，光比声音传播得快。
