名词性语从句重难点点拨

同位语从句重难点点拨●●同位语从句是疑问句时，应根据语境选用who,when,where,how,whether(不能用if)等词来引导。如：Thequestionwhoisthebestforthejobrequiresconsideration.●分隔式同位语从句：当主句的谓语较短，而同位语从句较长时，为了使句子保持平衡，常把同位语从句后置。如：Anideacametohimthathecouldbuyheradiamondring.●后面常跟同位语从句的词有：doubt,fact,hope,idea,message,news,possibility,promise,question,suggestion,truth,thought,warning,wish

等表示建议、命令的词后的同位语从句中的谓语动词须用(should)+动词原形。如：Hemadethesuggestionthatthemeeting(should)beputoff.●同位语从句和定语从句的区别：①同位语从句和定语从句一般是放在某一名词后面，但同位语从句是对该名词的解释和说明，而定语从句是对该名词的修饰，说明它的性质特征。②Wearegladatthenewsthathewillcomesoon.(同位语从句)Thenews(that)hetoldmewasreallysurpri-sing.(定语从句)③wh-引导词引导同位语从句时，有其本身的疑问含义；引导定语从句时，则没有疑问的意思。如：Ihavenoideawherethemeetingwillbeheld.(同位语从句)HeistheonlyoneoftheseboyswhocanspeakFrench.(定语从句)【练习】选出可以填入空白处的最佳选项。1.Wehavearguedovertheproblem________thereislifeonotherplanets.
