Homework 假定你是李华，你校英文报“Teens”栏目正在策划一期“青少年健康”的专题。请你根据学校近期对学生睡眠情况的调查结果（图表），以“A Wake-up Call for Insufficient Sleep”为题，写一篇短文投稿，内容包括： 1.图表反映的问题；2.你的看法。 注意： 1.词数80左右； 2.可适当增加细节，以使行文连贯。 A wake-up call for insufficient sleep __________________________________________________________________________________________________________________________________________________________________________________________ Homework A wake-up call for insufficient sleep A recent school survey on sleep presents a disturbing picture. As the data shows, 45% of the students sleep less than 6 hours daily, and 40% get only 6 to 7 hours. Merely 15% enjoy the recommended 8 to 10 hours of rest. Clearly, insufficient sleep has become a serious issue among teenagers. In my opinion, this situation calls for immediate action. First, schools, teachers and students should make joint efforts to create a healthier balance between study and rest. Second, students must manage time wisely and avoid using phones late at night. Most importantly, everyone needs to realize that sleep is as vital as studying for our health and academic performance. Let’s wake up to this crisis and prioritize our rest starting tonight. Homework 二选一 假如你是李华，你的美国朋友Philip写信告诉你，由于父母工作变动，他转学去了一所寄宿学校（boarding school）， 但是他对寝室生活不太适应，所以常常失眠，因此他很痛苦。请你给他回一封信，内容包括： 1. 安抚他的情绪；2. 提供两条关于促进睡眠的建议。 注意： 1.词数80左右； 2.可适当增加细节，以使行文连贯。 Dear Philip, _______________________________________________________________Yours Li Hua Dear Philip, I’m sorry that you are having sleep problems since you transferred to this boarding school. The first few days, if not weeks, of living on campus can be really challenging. But there’re still ways to change the situation. For example, make sure that all the curtains have been drawn before you sleep, which effectively creates a safe and peaceful feeling. And making yourself tired both physically and mentally in the daytime can also help you fall fast asleep. What else do you want after a long day of hard work and hard play, but a good night’s sleep, anyway? I hope these two tips can work wonders on you as they once did on me. Just try and take care of yourself! Yours Li Hua Homework Thank you for your listening Lavf58.46.101 $
