【简答题】
根据短文内容,从短文后的选项中选出能填入空白处的最佳选项,选项中有两多余选项。 Every student has tests when they are at school. But have you ever been so worried about the tests that you can’t fall asleep at night? Have you ever felt sick or had a headache during a test? 小题1: This worry in your mind can make your body feel bad. You may feel angry, frustrated, scared, or afraid --- which can give you a stomachache or a headache. 小题2: Good or normal stress might happen when you are called to answer a question in class or when you have to give a speech. This kind of stress can help you to get things better done. 小题3: But bad stress can happen if the stressful feelings keep going over a long time. You may not feel well if your parents are fighting, if a family member is ill, if you are having problems at school, or if you are going through anything else that makes you upset every day. 小题4: 小题5: That means making good decision about how to spend your time. If you are only dealing with school stuff and have no time to play, you can get stressed. Make sure you keep your SELF in mind: Sleep, Exercise, Leisure and Food. If you take care of yourself and get enough sleep and food, and if you exercise and leave time for fun stuff, you will probably be less stressed out! A.However, there are two different kinds of stress. B.Can you tell a kind of stress from another one? C.The best way to keep stress away is to have a balanced life. D.That kind of stress isn’t going to help you, and it can actually make you sick. E. Since bad stress is harmful for us, you’d better try to change it into good stress. F. If so, then you know what stress is. Stress is what you feel when you are worried or uncomfortable about something. G. For example, you may do a better job on your test if the stress pushes you to prepare well before the test.
