（二）从句
从句的内容非常庞杂，该专题主要讲解在翻译题可能考察的名词性从句、定语从句、状语从句等。
一、名词性从句
名词从句是指行使名词功能的从句，包括主语从句、宾语从句、表语从句、同位语从句以及补语从句。
1.主语从句——从句作主语
主语从句主要由that, what, whether, how以及其它词引导，还有就是由代词it作形式主语。
That he survived the accident is a miracle.他在这场事故中幸免于难，真是奇迹。
特别提示：尽管that并没有实际含义，但是他起到引导主语从句的功能，在这里不可或缺。
What he enjoys doing is ignored by society as of no value or importance.他喜欢做的事情被社会所忽视，认为毫无价值，无足轻重。
How he managed to finish the job is of interest to us all.他是如何设法完成这项工作的，我们对
此都很感兴趣。
Whether the results will be valuable depends partly on our attitudes towards it.结果是否有价值在部分程度上取决于我们对此的态度。
特别提示：whether引导的主语从句位于句首时，whether不能由if代替。
2.宾语从句——从句作宾语。
The court decisions have ordered that public schools take the necessary steps to provide that education.法院裁决责令公立学校必须采取必要步骤提供这种教育。
I can’t understand why he avoided speaking to me.我不理解他为什么不跟我说话。

【CET-4：2007.12】In my sixties, one change I notice is that _____(我比以前更容易累了)。
参考答案：I am more likely to get tired than before
4.同位语从句——从句作同位语
同位语从句在句中作同位语，对被修饰名词的内容予以解释说明。特点：抽象名词在前，表达具体内容的从句在后。常见的包括：
agreement, assumption(假设), belief, conclusion, decision, determination, discovery, dream, evidence, explanation, fact, guess, hope, idea, knowledge, likelihood, message, mind, news, notion(观念), opinion, possibility, prediction(预言), proposal, proposition(论点，主张), suggestion, rumor, theory, thought, truth
I have no doubt that he will overcome all his difficulties.他会克服一切困难，对此我并不感到怀疑。
二、定语从句
定语从句是修饰限定名词或代词的从句。掌握定语从句的关键在于把握引导词，既用来引导定语从句的词。定语从句的内容比较庞杂，希望同学们在复习时多总结和归纳。

参考答案：the more confused I am
二、强调句
1．It is/was +被强调部分+that/who…
对于这个结构，需要注意以下几点：
①强调句型中的系动词除is和was之外，没有其他形式的变化;
②被强调部分如果是人，可以用who, 也可以用that,其他情况用that（常识性知识，一般不能作为考点）。
③在not…until句型里，如果强调由until所引导的时间状语时，not须跟在until之前，即构成It is not until…that结构。

她不知道如何应对这种严重情况是因为她太缺乏经验了。

they could not cross the river.
