        熬夜的英語演講稿1

        Do you always work or study until midnight?

        Do you often hang out or spend much time in pubs at late night?

        If you answered yes to either of these questions, you are unfortunately one of the large groups of people who always stay up late. Because of the fierce competition in the society, it seems that everyone has endless work to do and twenty-four hours per day is not enough. Therefore, an increasing number of people stay up late in order to finish the mountainous work. Besides, lots of young people enjoy entertaining at late night. However, many of them are still not aware of the bad effects of staying up late. In fact, it does severe harm to us in three aspects, namely physical health, work efficiency and mental stress.

        In the first place, staying up late badly impacts on our physical health condition. The human adrenal cortex hormone and growth hormone, which are vital substances for human body, only secrete at night. The former secretes before the dawn facilitating the carbohydrate metabolism and protecting the development of muscle function. The latter only secretes after sleeping. It can improve the growth of the young and slow down the aging of the elderly. However, if people often stay up late, the secretion of these two substances will be gravely impacted. Finally, our health condition will be degraded. It can cause a variety of harms to human body. Normally, frequent staying up late will lead to fatigue and degraded immunity. People may easily get sick when the weather gets a little bit colder or hotter. In addition, it can also cause headache. People may feel heavy in the brain and dizzy for a whole day. Besides, the fertility of both male and female will be impacted. For women, it will affect the secretion of female hormones and the quality of ova. It also tends to affect the menstrual cycle. For men, both the quality and quantity of sperm will be impacted. What is more, staying up late can also damage people’s eyesight, skin and memory capacity, and cause black eyes as well.

        Furthermore, it negatively impacts on the work efficiency. On the one hand, owing to the discomfort of your health as mentioned above, you may feel distracted from the work. On the other hand, because of the decrease of the memory capacity, your work efficiency will be lower, which means that you may not complete the things as you want. Assume that you are a university student and you plan to review for your psychology examination next week after tomorrow’s class. Nevertheless, you stayed up late yesterday for some reason. Therefore, you probably be late for tomorrow’s class or even skip it. Thus, you must find other time to compensate for it. Afterwards, when preparing your examination, you may feel headache and cannot concentrate on it, thus having difficulty memorizing and understanding the psychological terms and principles. Therefore, your schedule for reviewing chapter 2 and chapter3 will be changed. You can only review chapter 2 and may not finish chapter 3. However, in order to finish reviewing on time, you are more than likely to stay up late again. Then, you will be in the vicious cycle and your work efficiency will be lower and lower.

        What is also noticeable is that staying up late can bring about mental stress. Since your work efficiency is lower, you probably doubt yourself whether you are a capable person or not. You may think you are not so smart as others and even fear yourself that you can hardly get a good grade in your psychology examination, which makes you feel more anxious and upset. Besides, if you frequently stay up late, you definitely look tired and in low spirits. Therefore, when working on a group project, maybe nobody wants to be in the same group with you, a low-efficient and anxious person. Thus, you will feel separated from others, which possibly makes you more stressed and upset.

        In conclusion, although we have a lot of work to do and various activities to participate in, staying up late is by no means a good choice for us. It badly impacts on our physical health, lowers our work efficiency and makes us stressed and anxious. Faced with too much work, we should make good arrangements in advance and maintain a healthy lifestyle.

        熬夜的英語演講稿2

        With the College Entrance Examinations approaching , the students of Senior Three are focusing much more on studying. Many of them even begin to stay up studying. A heated discussion was held to argue about the advantages and disadvantages of it.

        Some students have their own reasons for studying late into night. Firstly, the quietness in the night will result in better effectiveness. Besides,

        the examinations are only 200 days away so it's high time they made good use of every minute. What’s more, seeing others studying so hard, they will feel anxious if they don’t take action.

        Some others, however, hold the opposite view, saying that a sensible senior student must know how to balance his time between study and leisure. As everyone knows, staying up late will naturally affect the next day's performance in class.

        As far as I’m concerned, different people have different habits. If you can hold it, it’s your own business when to study and when to sleep.

        Many people want to ask, what is the best time for sleep? Do we need to sleep early or late? My opinion is to sleep early. Here is the reason why we should sleep early. First, it will make you more healthy. Sleep late would cause illness, long time not sleeping early will damage your body. Second, many people had said that if you don't get many time to sleep, and you sleep late would make black rim of the eye. That is not healthy also, and it's not beautiful. We should give our body a rest. Sleep is the best way. Well, there are certain time that is best for us to sleep. Sleep early is definitely better than sleep late. Also, we should not keep awake the whole night. You don't feel the damage when you are young, but when you get older, the problem start to appear. Many disease of heart and lung started from not sleep at night. Many youth think it is fun to keep awake or sleep late. But I don't think so. Keep your body healthy. I strongly suggest to sleep early.
