考研英语中出现的主语从句，通常以It 作形式主语置于句首，而that引导的真正的主语从句置于句末。下面就以真题为例句，解析这种句型的阅读技巧。

　　1. Is it true that the American intellectual is rejected and considered of no account in his society? (2006年翻译上下文)

　　这是一般疑问句，用it作形式主语，that 引导的从句是真正的主语，从句中用and并列谓语，且都用被动语态。整句可以翻译为：在他们所在的社会中，美国知识分子遭到拒绝，并且不受重视，这是真的吗?

　　2.Surely it should be obvious to the dimmest executive that trust, that most valuable of economic assets, is easily destroyed and hugely expensive to restore—and that few things are more likely to destroy trust than a company letting sensitive personal data get into the wrong hands. (2007年Text4)

　　整个句子是It作形式主语，that引导的并列主语从句，中间加入逻辑主语to the dimmest executive。并列主语从句1中，that用作代词，指代前文中的trust;并列主语从句2中，使用了比较结构——few A形容词比较级B than C， 意为“没有A”比C更B”。整句可理解为：确实，对最迟钝的管理人员来说，应该显而易见的是：信任是经济财产中最有价值的部分，它很容易遭到破坏，并且恢复起来代价昂贵;没有什么事情比一家公司让敏感的个人数据落入坏人之手更可能破坏信任。

　　3. And it is imagined by many that the operations of the common mind can be by no means compared with these processes, and that they have to be acquired by a sort of special training.(1993年翻译74题)

　　整个句子是it 作形式主语，两个that从句并列，作为真正的主语。可理解为：“许多人认为，普通人的思维活动根本无法与科学家的思维过程相比，并认为这些思维过程必须经过某种专门训练才能获得。”
