thatisaninterestingstory．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。2.不可以省略二、何时使用that引导的宾语从句e.g.Hesays(that)heislisteningtotheweatherreport．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。e.g.Ihope(that)hewillbefinesoon．我希望他很快好起来。e.g.Hesays(that)heislist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.Doyouthink(that)

theradioistoonoisy?你认为收音机太吵吗？三、that引导的宾语从句相关的内容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.Hesays(that)theyhavereturned

already.他说他们已经回来了。2.时态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.Hesaid(that)heboughtanewdictionary.他说他买了本新词典。如果主句用一般过去时，从句要用过去时态的某种形式（一般过去时一般现在时
