Dentistsalwaysaskquestionswhenitisimpossibleforyoutoanswer.

这里it是形式主语，真正的主语是toanswer。impossible通常不以人作主语，而以不定式或从句作主语eg:Itisimpossibleforhimtohelpyou.=Itisimpossiblethathewillhelpyou.

1.meanwhileadv.同时meanwhile=atthesametime=inthesametime用法和however一样，不能连接两个句子，但是意思上有承接概念2.系表结构系表结构有两部分构成：连系动词和表语。连系动词分为三类：be动词，感官动词，趋势动词。1)Be动词：am,is,are,was,were2)感观动词：sound,look,keep,taste,feel,smell3)趋势动词：appear,become,grow,get,turn,seem,remain,go

中考考点：并列连词（是用来连接同等的词，词组或分句）常用的有and,but,or,so,for,notonly...butalso...,either...or...,neither...nor...。1、and和or用在祈使句中：and=ifyou...，youll...;or=ifyoudont...，youll...例如：Getupquicklyandyouwillbethereontime.=Ifyougetupquickly,youwillbethereontime.如果你迅速起床，你就可以按时到那。Getupquickly,oryoullbelateforschool.=Ifyoudontgetupquickly,youllbelateforschool.如果你不迅速起床，你就会上学迟到。

2.当either...or...,neither...nor...,notonly...butalso...连接两个主语时，其谓语动词要与靠近的主语一致。Neithershenoryouarewrong.
