C．not so, as

D．more, than

Answer 1

C

試題分析：as...as意為"和……一樣"，表示同級的比較。使用時要注意第一個as為副詞，第二個as為連詞。其基本結構為：as+ adj./ adv. +as。其否定式為not as/so +adj./ adv. +as。例如： This dictionary is not as/so useful as you think.這本字典不如你想象的那樣有用。 根據語境可知此題選擇C。
點評：as…as中間一定要用形容詞或副詞的原級若有修飾成分，如twice, three times, half, a quarter等，則須置于第一個as之前。例如： Your bag is twice as expensive as mine.你的袋子比我的貴一倍。其否定形式第一個as可以變為so。
