–The classroom is_____ clean_____ it was yesterday.--Sorry, I forgot to clean it. A．as, as B．so, as C．not so, as D．more, than

Answer 1

C

试题分析：as...as意为"和……一样"，表示同级的比较。使用时要注意第一个as为副词，第二个as为连词。其基本结构为：as+ adj./ adv. +as。其否定式为not as/so +adj./ adv. +as。例如： This dictionary is not as/so useful as you think.这本字典不如你想象的那样有用。 根据语境可知此题选择C。 点评：as…as中间一定要用形容词或副词的原级若有修饰成分，如twice, three times, half, a quarter等，则须置于第一个as之前。例如： Your bag is twice as expensive as mine.你的袋子比我的贵一倍。其否定形式第一个as可以变为so。
