题目内容

12．This maths problem is _______ that one．（　　）

	A．	so easy as		B．	as difficult as
	C．	much difficult than		D．	less easier than

分析这个数学难题和那个一样难．

解答答案：B 根据This maths problem和that one可知，这是"这个数学难题"和"那个"两者之间的比较，as+形容或副词原级+as，表示"二者一样"，难的原形为difficult．故选B．

点评判断形容词或副词的比较级和最高级，主要是看几者之间的比较．两者之间用比较级，三者或三者以上比较用最高级形式．要掌握一些固定句式：as…as"…一样"；not as/so…as"…不如…"．
