题目解答
答案
### 解析
这道题要求我们找出句子的主要思想。首先,我们需要理解句子的结构和内容。句子提到一项研究,该研究分析了数千名参与者多年的数据,研究结果表明,定期锻炼不仅改善身体健康,还对心理健康有积极影响。
接下来,我们逐一分析每个选项:
- **选项A**:The study analyzed data from many participants.(这项研究分析了大量参与者的数据。)
- 这个选项提到了研究的一部分内容,即分析了大量参与者的数据,但并不是句子的主要思想。
- **选项B**:Regular exercise has multiple benefits.(定期锻炼有多种好处。)
- 这个选项概括了研究的主要发现,即定期锻炼不仅改善身体健康,还对心理健康有积极影响。这与句子的主要思想最为吻合。
- **选项C**:The study lasted for several years.(这项研究持续了多年。)
- 这个选项提到了研究的时间跨度,但并不是句子的主要思想。
- **选项D**:Mental well-being is important.(心理健康很重要。)
- 这个选项虽然提到了心理健康的重要性,但并没有直接反映句子的主要思想,即定期锻炼的多种好处。
### 答案
根据以上分析,句子的主要思想是定期锻炼有多种好处,因此正确答案是 **B. Regular exercise has multiple benefits**。
