四级写作常见话题及范文：压力

　　Stress is a common experience. We may feel stress when we are very busy, have important deadlines to meet, or have too little time to finish all of our tasks. Often people experience stress because of problems at work or in social relationships, such as a poor evaluation by a supervisor or an argument with a friend. Some people may be particularly vulnerable to stress in situations involving the threat of failure or personal humiliation. Major life events, such as the death of a loved one, can cause severe stress.

　　Stress can have both positive and negative effects. Stress is a normal, adaptive reaction to threat. It signals danger and prepares us to take defensive action. Fear of things that pose realistic threats motivates us to deal with them or avoid them. Stress also motivates us to achieve and fuels creativity. Although stress may hinder performance on difficult tasks, moderate stress seems to improve motivation and performance on less complex tasks. In personal relationships, stress often leads to less cooperation and more aggression. If not managed appropriately, stress can lead to serious problems.

　　The circumstances that cause stress are called stressors. Stressors vary in severity and duration. For example, the responsibility of caring for a sick parent may be an ongoing source of major stress, whereas getting stuck in a traffic jam may cause mild, short-term stress. Some events, such as the death of a loved one, are stressful for everyone. But in other situations, individuals may respond differently to the same eventwhat is a stressor for one person may not be stressful for another.

　　Stressors can be classified into three general categories: catastrophic events, major life changes, and daily hassles. In addition, simply thinking about unpleasant past events or anticipating unpleasant future events can cause stress for many people.

　　A catastrophe（灾难） is a sudden, often life-threatening calamity or disaster that pushes people to the outer limits of their coping capability. Catastrophes include natural disasterssuch as earthquakes, tornadoes, fires, floods, and hurricanesas well as wars, torture, automobile accidents, violent physical attacks.

　　Major Life Changes（生活变故）: The most stressful events for adults involve major life changes, such as death of a spouse or family member, divorce, imprisonment, losing ones job, and major personal disability or illness. For adolescents, the most stressful events are the death of a parent or a close family member, divorce of their parents, imprisonment of their mother or father, and major personal disability or illness. Sometimes, apparently positive events can have stressful components. For example, a woman who gets a job promotion may receive a higher salary and greater prestige, but she may also feel stress from supervising coworkers who were once peers.

　　Daily Hassles（日常烦心事）: Much of the stress in our lives results from having to deal with daily hassles pertaining to our jobs, personal relationships, and everyday living circumstances. Many people experience the same hassles every day. Examples of daily hassles include living in a noisy neighborhood, commuting to work in heavy traffic, disliking ones fellow workers, worrying about owing money, waiting in a long line, and misplacing or losing things. When taken individually, these hassles may feel like only minor irritants, but cumulatively, over time, they can cause significant stress.

　　Effects of Stress（压力后果）: A person who is stressed typically has anxious thoughts and difficulty concentrating or remembering. Stress can also change outward behaviors.

　　Disease（生病）: Physicians increasingly acknowledge that stress is a contributing factor in a wide variety of health problems. These problems include cardiovascular disorders such as hypertension （high blood pressure） and coronary heart disease （coronary atherosclerosis, or narrowing of the hearts arteries）. Stress also appears to be a risk factor in cancer, chronic pain problems, and many other health disorders.

　　There is substantial evidence that stress suppresses the activity of the immune system, leaving an organism more susceptible to infectious diseases.
