问题     The holidays are a time for eating: pies at Thanksgiving, chocolates for Advent and overflowing gift baskets of cookies and candies through the New Year. If you’re having trouble saying no to the bounty of fat and sugar, give yourself a break: your willpower may be no【S1】______for brain pathways that make overeating—much like drug-taking—feel so good.
    In one study by researchers at the University of Pennsylvania, mice that were fed a high-fat diet during the first 20 weeks of life and had become【S2】______showed significant and lasting changes in brain areas【S3】______in reward—making the brain less responsive to the same fatty foods.

In another study from Concordia University in Montreal, researchers found that hungry rats sought heroin when food was not there.

选项
答案N
解析 动词辨析题。根据本句结构，空格处应该为修饰性成分，因为本句的句子结构已是完整的“主语+谓语+宾语”，in brain areas在句中作状语，其后的成分修饰brain areas，因此需选用形容词或动词的分词形式，结合选项中能和in搭配的形容词或动词的分词形式，只有involved符合句意。involved in有“涉及；包含”的含义，所以involved符合原文意思。
