It’sthebesthotelthatIknow.2）非限制性定语从句：是先行词的一个附加语，对先行词起进一步说明作用，如果删掉它，主句的意义仍然是清晰的，非限制性定语从句与先行词之间有逗号。如：

Mr.Wang,whoiskind,ispopularwiththestudents.as引导定语从句

as用作关系代词，既可指人，也可指物。在定语从句中可作主语、宾语和表语。它常用在thesame…as…,such…as…,as…as…等句型中，as不能省略。

e.g.Iwillbuythesamebikeasyouhave.

我要买和你一样的自行车。as引导非限制性定语从句时，代表整个主句的内容。从句可放在主句前、主句后或主句中间。意思是“正如,像….一样”，从句动词经常是see,know,mention，imagine,mention,expect,pointout等词.e.g.Asweallknow,Chinahasbecomeaworldfamousnation.我们都知道，中国已成为一个世界闻名的国家。LuXun,asisknowntousall,wasagreatwriter.众所周知，鲁迅是位伟大的作家。as引导定语从句

which也可以引导非限制性定语从句,代表主句的所有内容,但是which从句只能放在主句后。关系代词which与as引导非限制定语从句的区别:☆关系代词which和as都可以引导定语从句用于指代前面整句的内容。☆as引导定语从句既可以放在句首，也可以放在句尾。意思是“正如……”后面的动词多是see,know,expect,say,mention,report,announce等。

Asisknowntoall,Edisoninvitedthetelephone.=Edisoninvitedthetelephone,asisknowntoall☆which引导定语从句,只能放在句尾，意思是“这一点……”。
