25、定语从句不能放在句首。意义不同：as引导非限制性定语从句时，还可译为“正如一样；就如一样”，而which不能；as引导的非限制性定语从句表示说话的依据、态度、解释或评论等，常用于as we all know(as it is known to us all),as is said(reported,mentioned,etc.),as it is等。which引导的非限制性定语从句表示某事的状态或结果。逻辑关系不同：当主、从句在意义上构成因果关系时，常用which代替as。如：Helen was much kinder to her youngest son than to the other

27、ptly she sat down,only to be scooped up by her laughing,shouting sister,Luna.她突然坐了下来，结果被爱吵闹的妹妹露娜一把抱了起来。句型公式 only to do/to be done 不料，结果却【句式点拨】句中only to do 是不定式作结果状语，意为“不料，结果却”，表示出乎意料或令人失望的结果。【相关拓展】不定式、现在分词作“结果”状语的区别：不定式作结果状语时，表示其动作发生在谓语动词之后，往往表示未曾预料到的或令人不快的事情，不定式前常加only；另外，还用于“tooto,enough to,never

28、to,so/suchas to”等固定结构中。现在分词作结果状语时，表示伴随谓语动词的发生而产生的自然结果(同时发生)，有时在前面加上thus，谓语动词与现在分词的动作是因果关系。【活学活用】(1)I hurried to the post office only to find it closed.我匆匆地赶去邮局，却发现它已经关门了。(2)They reached the company out of breath only _ they were fired.他们上气不接下气地赶到公司，不料却被告知他们被开除了。(3)He has migrated to Australia,thus _

29、 his family in Hong Kong.他移民澳洲，留下他的家人在香港。to be toldleaving(4)2012四川卷 Tom took a taxi to the airport,only _ his plane high up in the sky.Afinding Bto findCbeing found Dto have found解析 B 考查非谓语动词。句意：汤姆乘的士赶到机场，却发现他要乘坐的飞机已经飞入高空了。此处only后接动词不定式表示意想不到的结果。故选B。be aware of sth.that+从句意识到；知道 L5我们必须清楚地认识到许多动物正濒临
