1.【答案】C

【解析】题干问在美国每天大概需要多少献血者。文章第二句，根据美国红十字会，每天超过40000的献血者被需要。故本题选C，AB均不选。

2.【答案】C

【解析】题干问大概每年有多少人献血？文章第一段最后一句，在美国，每年有9200000人献血。million是百万的意思，故选C，AB不选。

3.【答案】A 题干问根据文章，一些人不愿意献血是因为什么。文章第二段第一句指出出于害怕，有时人们不去捐献。out of...在这里的意思是出于....。A选项they are afraid of the process她们害怕过程，故选A。B it isn't always convenient to schedule a time 安排时间总是不方便的 C they are concerned about their privacy他们担心他们的隐私，BC选项文章没有提及，均不选。

4.【答案】C

5.【答案】A

解析

文章主旨：本文主要介绍献血的重要性和相关流程，强调献血对拯救生命的意义，并说明献血的步骤和频率。
考查要点：

  1. 具体数字提取（如每日献血需求、年献血人数）；
  2. 原因分析（人们不献血的原因）；
  3. 细节对比（献血步骤的排除）；
  4. 时间间隔（献血频率）。
    解题核心：通过定位关键词（如“every single day”“eligible”“process”）快速锁定答案区域，注意单位转换（如“million”）和逻辑关系（如“although...less than”）。

第4题

关键信息：文中步骤为“registering, getting your medical history checked, donating, and having some food”，未提及“eating food before you donate”（选项C）。

第5题
