在复合句中, 作主语的从句称为主语从句。一、主语从句的引导词及其在句中的功能（一）连接词that和whether1. that引导主语从句, 在从句中不充当任何成分, 仅起连接作用, 但不能省略。2. whether引导主语从句, 在从句中不充当任何成分, 起连接作用, 但有自己的意义, 不可省略。
注意：that、whether引导的主语从句既可放在句首, 也可放在句尾（放句尾时前面需用it作形式主语）。例如：1.That she culd cme t help us made us very the big earthquake had killed many peple frightened peple all ver the we g by train r by bat makes n difference.4. It is still unknwn whether the plan will be carried ut.
（二）连接代词wh, whse, whm, what, which, whichever, whever, whmever, whatever
二、主语从句与形式主语it英语中, 常常可以用it作形式主语, 而把主语从句放在后面。常见的用it作形式主语的主语从句结构：
三、主语从句的注意事项（一）从句的语序在任何情况下, 主语从句都用陈述句语序。1.Whichever f yu gets here first will get the he succeeded is still a puzzle.（二）主谓一致1. 从句作主语时, 后面的谓语动词一般用单数形式; 但what引导的主语从句, 后面的谓语动词应与作表语的名词在数上保持一致。
2. 如果由and连接两个或两个以上的主语从句作主语时, 谓语动词用复数形式; 由两个或多个连接词引导一个主语从句时, 谓语动词用单数形式。例如：1. What they need are bks.2. What they need is lve.3. When they will start and where they will g have nt been decided yet.4. When and where the meeting will be held has nt been decided.

【命题立意】词义猜测题。【解题思路】本题题干意为：第一段中的词组“mney with n strings attached”是什么意思？该词组是整个文章的核心信息。文章讲述Tyler Bridges在洛杉矶的Unin Statin放了一块公告牌, 上面钉着一些钞票, 并写着“留下你所能捐赠的, 拿走你所需要的”。因此C项（无条件提供的钱）符合题意。

3. Why did Bridges carry ut the prject?( )A. T d a test n peple’s mrals.B. T raise mney fr his cmpany.C. T earn himself a gd reputatin.D. T prmte kindness and sympathy.
[解析] 【命题立意】推理判断题。【解题思路】根据第四段的Bridges said the nly gal was t shw genersity and sympathy. （Bridges说, 唯一的目的是展示慷慨和同情。）可知, 他开展这项研究的目的是宣传善良和同情心, 故D项正确。
