四级听力|篇章真题2|健康科普类
今天这篇听力就研究了这个问题！让我们来一“听”究竟吧！✍️ Tips
篇章听力难点不在于单词有多难，而是持续听、抓考点的能力。日常练习建议：
1. 第一遍做题，模拟考场，不暂停；
2. 第二遍对照原文，标记没听懂的句子；
3. 第三遍跟读，熟悉语音连读，积累话题词汇。
Questions 19 to 21 are based on the passage you have just heard.19. A) They have smaller amounts of nutrients than unprocessed diets.
B) Their contribution to calorie consumption is hard to determine.
C) They account for nearly half of the average American diet.
D) Their low price and convenience negatively impact health.
20. A) A strong desire to overeat. B) A lack of nutrients like fiber. C) A higher risk of cancer and obesity. D) A greater intake of sugar and salt.
Highly processed foods—the kinds made with lots of sugar, fat and salt—make up as much as sixty percent of the average American diet. But a new study shows that their low price and convenience come at a cost to health.The study found that when people ate a highly processed diet, they consumed about five hundred more calories per day than they did when they ate a less processed diet. They also gained two pounds over two weeks even though both diets had the same amounts of nutrients like sugar, fat, fiber and salt. It was a shock to find highly processed foods weren’t healthy. Other research has linked them to a higher risk of cancer and obesity. What was unexpected was that sugar, fat and salt didn’t seem to be the cause of these risks. This is the first trial to demonstrates that something about highly processed food made people independent of those nutrients that causes people to overeat. The study also found that when eating a highly processed diet, people ate faster. This could be one reason why they gained more weight. Highly processed food is softer, which makes it easier to chew and swallow.One theory is that if you eat faster, your stomach may not be giving enough time to signal to your brain that you’ve had enough calories and that you’re full. By the time the brain gets that signal, you’ve already overeaten.19. What does a new study show about highly processed foods?20. What are highly processed foods linked to according to other research?21. What do people tend to do when eating highly processed foods?
1. 视听一致 + 同义替换
四级听力篇章，大部分正确选项都可以听到原词（视听一致）；还有一部分是同义替换，比如ate faster = eat more quickly。
⚠️注意：听到原词不等于一定是答案，要核对问题问的是什么，小心 “答非所问” 的干扰项。
2. 预读选项，预判文章主题
拿到题目，快速扫读选项，这篇反复出现processed foods，可以预判文章主题：深加工食品对人体的影响。提前建立话题认知，听的时候更容易跟上节奏。
3. 顺序原则！题目和音频顺序完全对应
篇章听力严格遵守题文同序：第 19 题答案在音频开头，20 题在中间，21 题在后面。听到第 19 题选完，立刻把注意力转移到 20 题选项，不要纠结上一题。
4. 信号词后面是考点
听到下面这些信号词，集中注意力，答案大概率就在后面：
✅转折：but, however
✅举例：for example
✅观点 / 研究：study found, research shows
✅因果：because, reason why
✅递进：also, furthermore
