第三部分 阅读理解
阅读下面短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
While food gives people energy, it can also make people happier. Usually when people are feeling depressed, they go see a psychologist, but food can also lift people’s spirits. Scientific studies show that some foods can help fight against depression. Read on to find out more.
1. Deep sea fish
Studies show that people living by the sea appear much happier than those living inland, partly because the fresh sea air helps them clear their minds and partly because people by the sea eat a lot of deep sea fish. A study by Harvard University points out that the Omega-3 fatty acid contained in deep sea fish functions the same as anti-depression drugs which help calm nerves and increase the amount of serotonin (血清素).
2. Banana
Banana contains a natural chemical compound called alkaloid, which increases people’s confidence. Bananas are also a source of tryptophan (色氨酸) and vitamin B6, both helping the brain to manufacture serotonin.
3. All-wheat bread
Carbohydrates (含碳水化合物的食物) increase the amount of serotonin. Massachusetts Institute of Technology (MIT) researchers say it makes good sense that some people eat desserts and food made with flour as anti-depression drugs.
4. Cherry
Western doctors call cherry a natural aspirin because this fruit contains a material called anthocyanin which can make people happy. Researchers at the University of Michigan point out that eating 20 cherries is more effective than medicines that reduce depression.
5. Pumpkin
Eating pumpkin can help get people into a good mood because it is rich in vitamin B6 and iron, which both transform the sugar stored in the body to glucose (葡萄糖), which fuels the brain.
6. Low fat milk
Studies find that after taking calcium (钙) pills for three months, those women with pre-menstrual syndrome (经期前综合症) have a less stressful time and are less likely to feel nervous or anxious. Milk, yogurt and cheese are a major source of calcium. Low fat or skim milk contains the most calcium.
7. Chicken
After some British psychologists fed their subjects 100 mg of selenium (硒), they found that their subjects all felt happier. Chicken is a major source of selenium.
1. Which part of the body produces serotonin?
A. Blood. B. Stomach. C. Muscle. D. Brain.
2. If you want to increase your confidence, which kind of food had you better eat?
A. Pumpkin. B. Dessert. C. Banana. D. Chicken.
3. What does the underlined word “subjects” in the last paragraph refer to?
A. Areas of knowledge studied in a school.
B. Persons being used in an experiment.
C. The doers of an action.
D. Persons who are under the rule of others.
4. What would be the best title for this passage?
A. How to fight against depression
B. 7 foods used as medicines
C. 7 foods that make people happier
D. A new discovery of depression
