单选题 A major part of managing stress is to recognize those situations you can change, and to learn to accept those you can't change. When you can separate those situations that you have control over from those you don't, then you will know when to take action and when to "let go" of problems you can't resolve.
Often pressures from outside sources can cause stress. We have two options: we can either change the demands on us or change the way we think and react to the demands. Sometimes we have to acknowledge that the demands are unreasonable. Then we either accept them or work to change the demands. For example, let's say a teacher gives you homework with a deadline. Given your other obligations (责任，义务), you first think that the task is unreasonable; you think you need more time to complete the assignment. You have two possible choices. You can try to change the demand, e.g. ask the teacher for an extension (延期), or you can accept the situation by changing your perception of it, e.g. by thinking that the assignment is simple. In the latter case, you may need to re-evaluate and change your other obligations. By recognizing that you have a choice--to either change the demands on you or change your perception and reaction to the demands--you will feel that you are in control.
As you read through your list of stressors, identify one or two things in your life that you can change easily and that will make a difference to you. Take action on those couple of things that will have the biggest positive impacts on your life with the least amount of effort. Resolving even a couple of things in your life may bring much relief.
