句型公式the fact that………的事实【句式点拨】本句是由that引导的一个同位语从句,用于解释和说明fact的内容。引导词that不能省略。

经常跟同位语从句的名词有fact, news, message, doubt, possibility, idea, reason, belief, hope, thought, promise, suggestion, question等。引导词有:毗连词that, whether;毗连代词who, which, what;毗连副词where, when, why, how等。

[温馨提示] 使用同位语从句要注意以下两点:(1)同位语从句在句中的位置。一般情况下同位语从句跟在某些名词(如news,idea,fact,promise,hope,message等)的后面,用于说明该名词所表达的详细内容。有时同位语从句可以不紧跟在它所说明的名词后,而被此外词语离隔,这在语法上叫作分开式同位语从句。

如:The thought came to her that maybe she had left the door open when she left home.她想起她可能在脱离家时没把门关上。(2)同位语从句的语气。

在suggestion,advice,request,order等意为"建议,要求,下令"的名词后,同位语从句中的谓语动词通常用"should+动词原形"的虚拟语气结构,句中的should可以省略。如:The suggestion came from the chairman that the new rule (should) be adopted.主席提出建议,应采取新规则。【活学活用】(1)I admired the fact that he would talk to students outside the classroom or talk with them on the telephone. 我羡慕他经常在课外与学生谈天或通过电话与学生谈天。

同类表达另有:The advantage/strength of…is that………的优势是……;The disadvantage/drawback of…is that………的不足/缺点是……。【活学活用】(1)The advantage of the emotions is that they lead us astray, and the advantage of science is that it is not emotional.情感的利益就是把我们引入歧途,而科学的利益是不情感用事。

(2)The advantage of smiling is that it can not only make us happy,but also please others.微笑的优势在于它不仅仅让我们兴奋,还能取悦别人。(3)I like fishing. ________________I can take in fresh air in the open air.我喜欢钓鱼。其优势之一就是我可以呼吸户外的新鲜空气。
