【辨析】deal with与do with
①deal with作“处理”讲时,常与疑问词how连用。
②do with作“处理”讲时,常与疑问词what连用。
But people don't take as much exercise as they used to.但是人们所做的运动不像过去一样多了。
A)as...as...意为“像······一样······”,第一个as是副词,第二个as是连词,常用于同级比较,其否定形式为not as/so...as...。主要用法如下:
①“as+形容词/副词的原级+as”结构可用来表示两者在某方面相同或相近。
eg:This film is as interesting as that one.这部电影和那部电影一样有趣。
②“倍数+as+形容词/副词的原级+as”结构可表示两者间的倍数关系。
eg:He runs twice as fast as I do.他跑得有我两倍快。
B)used to意为“过去(常常)”,其后常接动词原形,含有今昔对比之意。
eg:He used to play basketball after school.他过去常常在放学后打篮球。
【拓展】①used to的否定形式为usedn't to或didn't use to;其疑问形式为Used+主语+to do...?或Did+主语+use to do...?
②be used to doing sth. 意为“习惯于做某事”,指动作过去不常做而现在已习惯做了,强调目前的情况;to为介词,后接名词或动名词。
③be used to do sth. 意为“被用来做某事”,为被动语态。
