且在定语从句中都可以作主语和宾语。2.as和which引导非限制性定语从句的不同之处在于：(1)as引导的定语从句可置于句首,

而which引导的定语从句不可放在句首。(2)as代表前面的整个主句并在从句中作主语时,

从句中的谓语必须是系动词;

若从句中的谓语为行为动词，则从句中的关系代词只能用which。另外,

as引导非限制性从句,

常带有“正如”的意思。Alicereceivedaninvitationfromherboss,_____cameasasurprise.2.Theweatherturnedouttobeverygood,_____wasmorethanwecouldexpect.3.___isexpected,theEnglandteamwonthefootballmatch.AswhichwhichPractice关系代词：which/who/whom/whose/as关系副词：when/where(非限制性定语从句中不用关系词that；非限制性定语从句中关系词不能省略)非限制性定语从句中通常使用下列关系代词和副词:all/some
