单选题 If you want to lose weight, you should not take such food ______.
  • A. as is not really necessary
  • B. as it is not really necessary
  • C. as it was not really necessary
  • D. as was not really necessary


【正确答案】 A
【答案解析】[考点] 考查定语从句。
such…as…表示“像…这样的”，其中的as用作关系代词，引导定语从句，as在定语从句中可以作主语或宾语，排除B、C。因为本句为一般现在时，故本题应该选A。
