She writes____than I.A.more careful B.much careful C.much more carefully D.much carefully
She writes____than I.
A.more careful B.much careful
C.much more carefully D.much carefully

优质解答

选C,因为本句中修饰的是动词writes,所以用副词的比较级,从而排除A,B两个选项,又因为carefully是多音节的副词,所以变成比较级时在原形前面加more,构成比较级,而much又修饰比较级,much more carefully是认真得多的意思,这句话的意思是：她写得比我认真得多.
