改錯:(1)The day breaks because the birds are singing.(2)Because the earth is round,why do we not fall off?(3)Because it is raining,we’d better stay here.請寫出分析過程.謝謝!

熱心網友

1) cause-----for,because表示充分必要的理由,回答why的提問,for表示推斷理由,因為鳥叫了不是天亮的必然充分且必要的理由,只是由"鳥叫"推出天可能亮了.(2)Sincetheearthisround,whydowenotfalloff?because--since,既然,由于,since表已知的事實,(3)Since/Asitisraining,we’dbetterstaycause----since/as,同上,as語氣比since弱.
