A
When we're stressed out, many of us turn to junk food for comfort. But a new study says this might not be a positive idea. The study found that eating a lot of fatty foods can change animals' brains in ways that make their anxiety worse.
The person who is responsible for the study, Christopher Lowry, says that we knew junk food could make us put on weight, but we didn't know it could also make us feel more nervous.
In an earlier study, they found the large mice that ate a lot of fat had more signs of brain inflammation(炎症) and acted more nervously. To better understand how a high-fat diet might be connected to anxiety, the researchers put some mice into two groups. Half got a standard diet of about 11% fat for nine weeks, and the others got a high-fat diet of 45% fat. They looked at the mice's gut(肠) health and then gave the mice tests to see how they behaved.
When compared to the control group, the group eating a high-fat diet, not surprisingly, were heavier. They also had fewer types of beneficial bacteria(细菌) in their guts. And they had more of certain things in their brains, which have something to do with stress and anxiety.
▲ Fats from food like fish can be good for our brains. But his research in animals suggests that too much fat, especially at a young age, might make the brain more likely to suffer from anxiety now and later in life.

1. C 细节理解题。根据“They looked at the mice's gut health and then gave the mice tests to see how they behaved.”可知，研究人员测试了老鼠的行为。故选 C。
2. A 图示理解题。根据“When compared to the control group, the group eating a high - fat diet, not surprisingly, were heavier.”可知，摄入脂肪越多，老鼠体重越重，两者呈正相关。故选 A。
3. A 推理判断题。根据“Fats from food like fish can be good for our brains. But his research in animals suggests that too much fat, especially at a young age, might make the brain more likely to suffer from anxiety now and later in life.”可知，像鱼肉等食物中的脂肪对大脑有益，但过多脂肪不好，所以这里是说并非所有脂肪都不好。故选 A。
4. D 主旨大意题。根据“The study found that eating a lot of fatty foods can change animals' brains in ways that make their anxiety worse.”以及全文内容可知，文章主要讲述了吃高脂肪食物可能会增加焦虑感。故选 D。
