The food we eat seems to have profound effects on our health.Although science has made enormous steps in making food more fit to eat ,it has, at the same time,made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well,especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is nto a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats,and other food additives,caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this ,penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes,but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration(FDA) has tried repeatedly to control these procedures, the practices continue. The word 'carcinogenic' most nearly means '___'.a.trouble-making b.color-retaining c.money-making d.cancer-causing
共用题干 DepressionEveryone occasionally feels blue or sad.But these feelings are usually short-lived and pass within a couple of days.Depression is a common but serious illness.Major depression prevents a person from functioning normally.It interferes with a person's ability to work,sleep,study,eat,and enjoy once-pleasurable activities.Minor depression is character-ized by having symptoms for 2 weeks or longer that do not meet full criteria for major depression. Without treatment,people with minor depression are at high risk for developing major depressive disorder.The severity,frequency,and duration of symptoms vary depending on the individual and his or her particular illness.They include persistent sad,anxious,feelings of hopelessness,guilt,worth-lessness,or helplessness,loss of interest in activities or hobbies once-pleasurable,fatigue and decreased energy,difficulty in concentrating,remembering details,and making decisions,insomnia, early-morning wakefulness,or excessive sleeping,suicide attempts.Depression also may occur with other serious medical illnesses such as heart disease,stroke, cancer,HI V/AIDS,diabetes,and Parkinson's disease.Depression is related to a combination of genetic,biological,environmental,and psychological factors.Research indicates that depressive illnesses are disorders of the brain.Brain-imaging tech-nologies,such as magnetic resonance imaging(MRI),have shown that the brains of people who have depression look different than those of people without depression.Some types of depression tend to run in families.In addition,trauma,loss of a loved one,a difficult relationship,or any stressful situation may trigger a depressive episode.Biological,life cycle,hormonal,and psychosocial factors that women experience may be related to women's higher depression rate.For example,women are especially vulnerable to developing postpartum depression after giving birth.Besides,during the transition into menopause,some women experience an increased risk for depression.It is still unclear,though,why some women faced with enormous challenges develop depression,while others with similar challenges do not.Some women experience an increased risk for depression when_________.A:feelings of guilt or worthlessnessB:developing postpartum depression after giving birthC:going through a transition into menopauseD:symptoms for 2 weeks that is slightly different from major depressionE:his family member has depression tooF: heart disease,stroke,cancer,HIV/AIDS,diabetes,and Parkinson's disease
