• 1）It is well-known that the earth moves around the sun. 众所周知，地球围绕太阳转。 （说明：由连词that引导的主语从句，在大多 数情况下用代词it作形式主语。）
• 2）Whether we will hold a party in the open air tomorrow depends on the weather. 我们 明天是否在户外开晚会要视天气而定。（此时 不能用if引导主语从句，只能用whether。）
• 有时如果主句的谓语动词较短，为保 持句子平衡，避免头重脚轻，同位语 从句也常与要说明的名词分开。例如： Word came that he died yesterday. 消息传来说他昨天死了。
• 说明：当名词doubt用在否定句中时， 其后的同位语从句应用that引导；而用 在肯定句或疑问句中时则可以用其他词 来引导。例如：
• 2．形容词性从句（即定语从句）（复 合句考查的重点）
• 定语从句主要用来修饰它前面的先行词 （名词或代词）的从句，所以又称形容 词从句。根据与先行词的关系，定语从 句可分为限制性定语从句和非限制性定 语从句。定语从句主要考查引导定语从 句的关系代词和关系副词；介词＋引导 词以及非限制性定语从句。对于定语从 句，在历年专业四级英语试题中，相对 集中地考查了非限制性定语从句、关系 代词和关系副词的选用、定语从句中的 一致关系以及"介词+关系代词"等知识点。
• 如： • 1）We heard the news that he had
won the game. 我们听到消息他赢得了 比赛。 试比较：
• 2）We heard the news that he had told her. 我们听到他对她说的消息。 （定语从句）
• 例2中的that从句的作用相当于一个形 容词，其作用是修饰the news；例1中 的that从句的作用相当于一个名词， 是对the news的进一步说明。
• 3）When the sports meet will be held is not decided. 何时举行运动会还没有决定。
• 4）Which car you will choose to buy makes no difference.
•
你决定买哪一辆车都不会有任何区别。
• 考点二：宾语从句：主要考查宾语从句if 与whether的用法区别：
名词性从句
• 名词性从句：即从句在整个句中起名词 作用，分别可以作主语、宾语、表语、 同位语等，所以这类从句包括主语从句、 宾语从句、表语从句和同位语从句。名 词性从句侧重考查考生在一定的语言环 境下对英语从句的语序、从句连接词的 运用以及主从句时态的呼应等知识点的 掌握；
• 考点一：主语从句：主要考查主语从句的引导 词；主句的谓语动词，一般用单数。
• 考点一：引导定语从句的引导词有关系代 词（who, whom, which, that, whose）和 关系副词(as, when, where, why)等。但是 当下列情况出现时，对引导词有特殊要求。
• 1） 当先行词是all, everything, nothing, something, little, much时；当先行词被all, no, some, any, every, a few, a little, much, only, very修饰时；当先行词被序数 词或形容词最高级修饰时，或者先行词既 有人又有物时，定语从句的引导词用that。 例如:
• 同位语从句的特点是由一个抽象名词 +that从句构成，引导词一般是that, 而 且that在从句中不充当任何成分。这些 抽象名词有：news, idea, fact, doubt, evidence, promise, rumor, hope, truth, belief, message等，同位语从句是对抽 象名词进行说明解释。
• 考点三：表语从句：be动词或者系动词 后面跟主语补足语。
• 1）The question is whether the book is worth reading at all.（问题是这本书 是否值得一读。） 2）That is why we don't like it.
• 考点四：同位语从句（专业四级英语考 查的重点）
英语从句专四考点归纳
从句定义
• 所谓从句是指从属于主句的句子，由从属连词 连接。由主句和从句构成的复合句，是英语中 比较复杂的句子结构。从句的种类有很多，但 根据其性质和作用可以分为：名词性从句，形 容词性从句（即定语从句），副词性从句（即 状语从句）三大类。从句构成与用法的考查要 点很多，历来是专业四级英语考试试题的热点 与焦点，专业四级英语考试几乎每年都涉及到 对名词性从句、定语从句以及状语从句的考查， 常将并列连接词、从属连词、关系代词、关系 副词放在同一题干中进行考查，故意设置干扰 项，增加试题难度，以考查考生分析交际语境、 理解句子之间的逻辑关系的能力。
• I never have the doubt that you can look after yourself. 我从没有怀疑过你 可以照看好自己。
• Some people have the doubt how such a little boy can lift so heavy a box. 这 么一个小男孩怎么能举起这么重的盒子， 对此人们表示怀疑。
• 1）whether和if常与or not连用， whether和or not 既可合起来使用，也可 分开使用；if和or not只能分开使用。如： He asked whether (if) they would come or not. 他问他们是否该来。 I don't know whether or not they will come. 我不知道他们来不来。
• 2）whether 引导的宾语从句一般是肯定 句，if 引导的宾语从句可以是肯定if you had enough money. 她问你是否有足够的钱。 I don't care if it doesn't rain.我不 在乎是否下雨。（只能用if)
