5、your favourite colour matches your characteristicsIn informal English we often drop that.Step 4 Grammar explanationthat 引导的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。今天，我们就谈谈连接词that引导的宾语从句。请同学们关注以下几点：一、引导词本身的省略与不省略1. 可以省略连词that引导宾语从句，只起连接主、从句的作用，它本身无意义，在口语或非正式文体中常省略。如： He says (that) he is a Young Pioneer. 他

6、说他是个少先队员。2. 不可以省略从句的主语是that时，that不省略。如：We know that that is an interesting story我们知道那是一个有趣的故事。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。如：He says (that) he is listening to the weather report他说他正在听天气预报。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。如：I ho

7、pe (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, pleased, sad, sure, afraid 等等。如：Im afraid (that) he cant come恐怕他不能来了。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”。如：Do you think (that) the radio is too noisy? 你认为收音机太吵吗？2. 时态that引导的宾语从句

8、，主句用一般现在时，从句可以用符合句意要求的任一时态。如：He says (that) they have returned already.他说他们已经回来了。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）。如：He said (that) he bought a new dictionary.他说他买了本新词典。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。如：Our teacher told us that light travels faster than soun

9、d.我们老师告诉我们，光比声音传播得快。Finish Section A1. Talking about room coloursSandy is chatting online with Millie about room colours.

Anyway, we should choose the colour which makes us feel comfortable.whether 或if引导的宾语从句whether和if都可以引导宾语从句

14、，表示“是否”，在口语或间接引语中两者可以互换使用。其语序必须是陈述语序，即“连接词+主语+谓语+其他成分”。如：Ask him whether / if he can come. 问下他是否能来。但在有些情况下，whether和if的用法有一定区别。1. whether引导的从句常可以与连词or或or not直接连用，而if一般不能。如：正：Let me know whether you can come or not. 误：Let me know if you can come or not. 2. 当宾语从句提到句首时，只能用whether引导，而不能用if。如： 正：Whether i

15、t is true or not, I cant tell. 误：If it is true or not, I cant tell. 3. whether可以引导带to的不定式，if则不能。如： 正：I dont know whether to accept or refuse. 误：I dont know if to accept or refuse. 4. whether及其引导的成分可放于介词之后，作介词的宾语，但if不能。如： 正：I worry about whether I hurt her feelings. 误：I worry about if I hurt her feel

16、ings. 5. whether可以引导从句，作主语、表语或同位语，而if不能。如： 正：It was uncertain whether he would come. 误：It was uncertain if he would come.
