【句式分析】本句是主从复合句。主句主干是silk fund its way；what 是what 引导的名词性从句，作介词alng 的宾语。1 what 引导的名词性从句（1）what 引导的名词性从句可在句中作主语、宾语、表语和同位语。（2）what 在名词性从句中作主语、宾语、表语和定语。（3）what 有三种意思：什么；……的东西/ 事情等；多么。What made Lucy happy is the appintment with Tm. 让露西高兴的是和汤姆的约会。（what 在主语从句中作主语） The cnsumers believe in the salesman，s they believe what he has prmised. 消费者信任这个推销员，所以他们相信他所承诺的。（what 在宾语从句中作宾语） The street is mre like what it used t be 10 years ag. 这条街更像它10 年前的样子。（what 在宾语从句中作表语） I have n idea what happened t my ladder，which is easy t break. 我不知道我的梯子怎么了，它很容易坏。（what 在同位语从句中作主语）

【句式分析】本句是复合句，as recrded... 是非限制性定语从句，关 系代词as 后面省略了was。2 as 引导非限制性定语从句as 引导非限制性定语从句时的特点： （1）指代整个主句，as 意为“这一点”，也常译为“正如，如同”。（ 2）可位于主句之前、主句中间或主句之后，一般用逗号与主句 隔开。（3）常见搭配： as （is） reprted 正如所报道的as （was） expected 正如所料as is ften the case 事情常常是这样as yu can imagine 你可以想象得到as everyne can see 大家都能看出 as（is） mentined abve 正如上文所提到的as is knwn t all/as we all knw/as everybdy knws 众所周知As expected，her expensive handkerchief was stlen by Tm. 正如预料的那样，她那条昂贵的手帕被汤姆偷走了。［词汇复现］ As is knwn t all，leather shes last lnger than clth shes. 众所周知，皮鞋比布鞋耐穿。［词汇复现］
【误区警示】 （1）which 引导非限制性定语从句修饰整个主句时，只能位于主句 之后；主从句常有因果关系。The black cluds are gathering，which indicates that it is ging t rain sn. 乌云正在聚集，这表明马上就要下雨了。（ 2）非限制性定语从句中，which 后的助动词 be 不可省略，as 后面 的助动词be 可以省略。He felt guilty，as （was） shwn in his wrds. 他感到内疚，这一点从他的话中可以看出来。［词汇复现］
