2.When people think of improving their diet,they often talk about eating more fruits and vegetables.Others want to eat more fish and less red meat,in addition to reducing the amount of food they eat.But,they can improve their diets even more with just a simple addition.American researchers have found that a diet rich in spices can help reduce the harmful effects of eating high fat meals.Pennsylvania State University Associate Professor Shiela West led an investigation of the health effects of a spice-rich diet.Her team knew that a high-fat meal produces high levels of triglycerides(甘油三脂),a kind of fat,in the blood.She said,"If this happens too frequently,or if triglyceride levels are raised too much,your risk of heart disease is increased."
As part of the study,her team prepared meals on two separate days for six men between the ages of 30and 65.The men were overweight,but healthy.The researchers added about 30milliliters of spices to each serving of the test meal,which included chicken curry,Italian herb bread and a cinnamon(肉桂树皮)biscuit.The meal for the control group was the same,but it did not include any spices.
During the experiment,the researchers removed blood from the men every 30minutes for three hours.They found that antioxidant activity(抗氧化活性) in the blood of the men who ate the spicy meal was 13percent higher than it was for the men who did not.In addition,insulin(胰岛素) activity dropped by about 20percent in the men who ate the spicy food.
Shiela West says many scientists think that oxidative stress leads to heart disease.And what exactly is oxidative stress?Think of an apple that has been cut in half and set aside for half an hour or so.The cut side of the apple turns brown.That is a simple explanation of what happens when oxidative stress comes in contact with the inside and outside of our bodies.
Professor West says,"Antioxidants,like spices,may be important in reducing oxidative stress and thus reducing the risk of chronic disease."She adds that the level of spices used in the study provided the same amount of antioxidants found in 150milliliters of red wine or about 38grams of dark chocolate.
66.What does the author advise people to do in their diets?D
A.Eating large amount of food.
B.Eating less fruits and vegetables.

67.What is the function of spices according to the passage?C
A.To help people lose weight.
B.To cure chronic disease.
C.To reduce the risk of heart disease.
D.To cause oxidative stress.
68.What happened to the men who ate the spicy meal according to the experiment?A
A.The antioxidant activity in their blood became increased.
B.The insulin activity in their body became increased.
C.The level of triglyceride in their blood was increased.
D.The oxidative stress in their body was strengthened.
69.What does Professor West show by citing the example of a half apple?B
A.The whole thing can be divided into two parts.
B.It implies oxidative stress is harmful to our health.
C.An apple is the only food that contains antioxidants.
D.We can keep diseases away if we have an apple a day.
分析 本文主要写了富含香料的饮食有助于减少吃高脂肪食物的有害影响,抗氧化剂,如香料,可能是重要的,减少氧化应激,从而减少慢性疾病的风险.
解答 66.D 推理判断题.根据第一段最后一句American researchers have found that a diet rich in spices can help reduce the harmful effects of eating high fat meals.富含香料的饮食有助于减少吃高脂肪食物的有害影响章最后一段Antioxidants,like spices,may be important in reducing oxidative stress and thus reducing the risk of chronic disease抗氧化剂,如香料,可能是重要的,减少氧化应激,从而减少慢性疾病的风险.可以推断出作者认为吃少量有香料的食物.
67.C 推理判断题.根据句子Shiela West says many scientists think that oxidative stress leads to heart disease.可知许多科学家认为氧化应激导致心脏病.根据句子Antioxidants,like spices,may be important in reducing oxidative stress and thus reducing the risk of chronic disease抗氧化剂,如香料,可能是重要的,减少氧化应激,从而减少慢性疾病的风险.由此可以推断出香料的作用可以降低心脏病的发生.所以答案选C.
68.A 细节理解题.根据句子They found that antioxidant activity(抗氧化活性) in the blood of the men who ate the spicy meal was 13percent higher than it was for the men who did not他们发现的抗氧化活性(抗氧化活性)在那些吃辣的食物的人的血液是百分之13高于没有吃的人.所以答案选A.
69.B 细节理解题.根据West says many scientists think that oxidative stress leads to heart disease.what exactly is oxidative stress许多科学家认为氧化应激导致心脏.到底什么是氧化应激?为了证明什么是氧化应激,举了半个苹果的例子,为了说明氧化应激对我们健康有害.所以答案选B.
