Question

To students, learning how to live is ________ important ________ learning how to study.

1. A.
   too; to
2. B.
   so; that
3. C.
   as; as
4. D.
   not only; but also

Answer 1

C
too…to意为“太……而不能”，其本身含有否定意义，而to之后接动词不定式，可见A不对。so…that意为“如此……以致”，that之后接结果状语从句，B也被排除。not only…, but also意为“不但……而且”，它通常接两个名词、形容词、介词短语或动名词，也可以接两个句子。但句中important是形容词做表语，显然两个动名词短语learning how to live和learning how to study做主句的主语和从句的主语，主句的谓语是is important，因此，此题的正确答案为C。
