5、e 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. 可以省略,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。,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。,e.g. 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,
6、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, pleased, sad, sure, afraid 等等。 e.g. 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”。 e.g
7、. 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，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。,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. 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、
8、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。,Sandy is chatting online with Millie about room colours.
