It is becoming more and more difficult to be sure that the food we eat is not actually harming us. We seem to get one food scare after another. Several of these, recently, have concerned genetically modified (GM,转基因) foods. Although some experts tell us that these foods will do us no harm and that the concern about them is just an excuse,What is people's main concern about GM foods?A. Some of them are not labeled with required informationB. They might pose hazards we don't know yetC. They don't have the same flavor as traditional foodsD.

### **题目原文:**
> It is becoming more and more difficult to be sure that the food we eat is not actually harming us. We seem to get one food scare after another. Several of these, recently, have concerned genetically modified (GM,转基因) foods. Although some experts tell us that these foods will do us no harm and that the concern about them is just an excuse,
然后问:
### **问题:**
> What is people's main concern about GM foods?
选项如下:
A. Some of them are not labeled with required information
B. They might pose hazards we don't know yet
C. They don't have the same flavor as traditional foods
D. The sowing of them will damage the environment

### **分析:**
题干中提到:
- 现在很难确定我们吃的食物不会伤害我们;
- 最近几次食品安全事件都与转基因食品有关;
- 尽管一些专家说这些食品不会伤害我们,人们的担忧只是借口。
从这些信息中可以看出,人们对转基因食品的担忧主要集中在**安全性**方面,尤其是**长期未知的风险**。
再看选项:
- **A** 说的是标签问题,虽然这也是一个担忧点,但题干中没有提到标签;
- **B** 表示“它们可能带来我们还不知道的危害”,这正是题干中提到的“担忧”的核心;
- **C** 是关于味道的,题干中没有提到;
- **D** 是关于环境的,虽然这也是一个可能的担忧,但题干中强调的是“我们吃的食物是否会伤害我们”,即对人体健康的担忧。

### **结论:**
正确答案是:

解析
考查要点:本题主要考查学生对语篇主旨的把握能力,需要结合上下文推断出公众对转基因食品的主要担忧点。
解题核心思路:
- 锁定关键信息:题干中明确提到“尽管专家认为转基因食品无害,但人们的担忧被当作借口”,这表明公众的担忧并非基于已知事实,而是对未知风险的担心。
- 排除干扰项:选项需与语篇中“食品安全性”这一核心主题相关,排除与“标签”“味道”“环境”等非直接相关的选项。
破题关键点:
- 语境暗示:语篇开篇强调“难以确定食物是否安全”,后续提到“转基因食品引发恐慌”,暗示公众的核心担忧是潜在危害。
- 逻辑关系:专家的“无害论”与公众的“担忧”形成对比,说明公众更关注不可预见的风险。
选项分析:
- A. Some of them are not labeled with required information
题干未提及转基因食品的标签问题,属于无关选项。 - B. They might pose hazards we don't know yet
与语篇中“尽管专家认为安全,但公众仍担忧”的逻辑高度契合,直接对应“未知危害”的核心主题。 - C. They don't have the same flavor as traditional foods
题干未涉及食品口味,属于主观臆断。 - D. The sowing of them will damage the environment
虽然环境问题是转基因食品的常见争议点,但题干明确聚焦于“食物是否伤害人类”,而非环境影响。
结论:
通过语境推断和逻辑对比,B选项最能反映公众对转基因食品的主要担忧。
