题目解答
答案
### 问题解析
这道题目要求选择一个合适的短语来填入句子中的空白处。句子的背景是关于在公共授权下,某种数字记录被用作旅行、上学、工作以及进入某些公共场所和其他日常事务的许可。这些记录的结果为旅行控制和差异化响应措施提供了基础,使得在不同地区和不同层次上进行风险识别和针对性控制成为可能。
### 选项分析
- **A. health QR codes**
- 这个选项指的是“健康二维码”。二维码(QR Code)是一种常见的二维条码,可以存储大量信息,通常用于扫描和验证身份、健康状况等。
- **B. health codes**
- 这个选项指的是“健康码”。健康码是一种数字凭证,通常用于表示个人的健康状况,可以是二维码形式,也可以是其他形式的数字记录。
### 选择理由
- **句子结构**:句子中提到“digital travel records”(数字旅行记录),这表明所填入的短语应该是与数字记录相关的。
- **上下文**:句子中提到这些记录被用作旅行、上学、工作等的许可,这与健康码的功能非常吻合。健康码通常用于表示个人的健康状况,以便在疫情期间进行旅行和进入公共场所。
- **具体性**:虽然“health QR codes”(健康二维码)也是正确的,但“health codes”(健康码)更为通用,可以包括二维码和其他形式的数字记录。
### 最终答案
根据以上分析,最合适的选项是 **B. health codes**。
### 完整句子
With authorization from the public, **health codes** and digital travel records have been employed as permits for making trips, going to school or work, and accessing certain public venues, and for other daily errands. The results shown on the codes and records provide a base for travel control and differentiated response measures, which has made risk identification and targeted control possible in different areas and at different levels.
解析
本题考查语境理解和词汇选择能力,需要根据上下文选择最合适的短语填空。关键点在于:
- 语境匹配:句子中提到“digital travel records”(数字旅行记录),表明需要填入与数字记录相关的概念;
- 概念范围:选项A(health QR codes)特指二维码形式,而选项B(health codes)是更通用的表述,包含二维码在内的多种形式;
- 逻辑连贯性:后文提到“codes and records”,若选择B选项,可与后文的“codes”形成自然对应。
选项对比
A. health QR codes
- 特点:强调二维码形式,属于健康码的具体表现形式。
- 问题:若选择此选项,后文“codes”可能重复强调二维码,与“records”搭配略显冗余。
B. health codes
- 特点:指健康码这一整体概念,包含二维码、颜色代码等多种形式。
- 优势:与后文“codes and records”形成逻辑衔接,既包含健康码本身,又与数字记录互补。
关键判断
- 语境需求:句子强调“数字记录”作为许可手段,需选择更通用的表述;
- 逻辑连贯:B选项使“codes”与“records”构成并列关系,表达更完整。
