54. Why can the habit of eating a plant-based diet lead to better health?
- A. It frees people from any known link to cancer.
- B. It provides all the nutrients for staying healthy.
- C. It helps maintain normal blood pressure and blood sugar.
- D. It reduces various health risks posed by meat consumption.
答案：D
答案句：If meatless meat can help you stick to a plant-based diet, that in itself can lead to better health. Not only has red meat been linked to cancer, but studies show that people who ditch meat have lower blood pressure, lower average blood sugar, and lower cholesterol levels.
参考译文：如果无肉肉能帮助你坚持植物性饮食，这本身就能带来更好的健康。红肉不仅与癌症有关，而且研究表明，戒肉的人血压更低、平均血糖更低、胆固醇水平也更低。
定位线索：题干“Why can the habit of eating a plant-based diet lead to better health”→答案句取自第5段“people who ditch meat have lower blood pressure, lower average blood sugar, and lower cholesterol levels”；文中“ditch meat”对应选项D“reduces various health risks posed by meat consumption”。
解析：答案句说明红肉与癌症相关，戒肉可降低血压、血糖和胆固醇，即减少肉类带来的健康风险，对应选项D。选项A“摆脱任何已知癌症关联”程度过重，选项B“提供所有营养”无中生有，选项C“维持正常血压血糖”只是部分内容，范围缩小。
55. What does the author recommend we eat at the end of the passage?
- A. Naturally produced foods.
- B. Processed protein substitutes.
- C. Red meats like traditional beef.
- D. New generations of alternate meat.
答案：A
答案句：These new generations of alternate meat get all the attention, but don't forget about whole grains and vegetables. Beans are an especially excellent protein substitute. They're nutritious, inexpensive, and far more sustainable than any of the processed meatless substitutes on the market today.
参考译文：新一代替代肉获得了所有关注，但别忘了全谷物和蔬菜。豆类是特别优秀的蛋白质替代品。它们营养丰富、价格低廉，比当今市场上任何加工的无肉替代品都更可持续。
定位线索：题干“What does the author recommend we eat at the end of the passage”→答案句取自末段“don't forget about whole grains and vegetables”和“Beans are an especially excellent protein substitute”；文中“whole grains and vegetables”和“Beans”对应选项A“Naturally produced foods”。
解析：作者在结尾推荐全谷物、蔬菜和豆类，这些是天然食物，对应选项A。选项B“加工蛋白质替代品”、C“红肉”、D“新一代替代肉”均与作者推荐相反，属于答非所问。
