11 When someone is said to "make a difference," what does this imply?A. The person has no impact on the situationB. The person has an effect on someone or somethingC. The person remains indifferent to the circumstancesD. The person is making a physical change to the environment

本题考查对英语短语“make a difference”含义的理解。解题思路是明确该短语的常见释义，然后将各选项内容与该释义进行对比分析。

• “make a difference”常见的意思是“产生影响；有所作为”。
• 选项A “The person has no impact on the situation” 意思是这个人对情况没有影响，这与“make a difference”的含义完全相反，所以A选项错误。
• 选项B “The person has an effect on someone or something” 表示这个人对某人或某事有影响，这与“make a difference”的核心含义相符，所以B选项正确。
• 选项C “The person remains indifferent to the circumstances” 指这个人对情况漠不关心，“漠不关心”和“产生影响”是不同的概念，所以C选项错误。
• 选项D “The person is making a physical change to the environment” 说的是这个人对环境进行物理上的改变，“make a difference”并不局限于物理上的改变，范围过窄，所以D选项不是最佳答案。
