Unit 1 Back to School 课时检测3Grammar and usage（Word练习）- 【新课程学案】新教材2023-2024学年高中英语必修第一册（牛津译林版2020）

1 / 5 UNIT 1 课时检测（三） Grammar and usage Ⅰ.阅读理解 A typical school day in the UK starts around 8：30 a．m.This is often even earlier than elsewhere in the world, with students sitting down to their first lesson at 7：30 a．m.in the US.The average teenager properly needs eight to nine hours' sleep each night, but in fact a lot of teenagers struggle to get this much.A lot of problems happen because our sleep patterns are not fixed, and they change as we grow. So a later school start time could help to solve this problem, by ensuring to get their eight plus hours of sleep and react properly to their body's natural rhythms (规律)．There has been a general change over the past 25 years to shorten the school day.This is not at the cost of teaching time (which has remained constant) but at the cost of natural breaks, which has led to reduced lunch time and lesson breaks. Later start times could help teens' grades and health.This is mainly because it makes the management of children easier.Managing hundreds of children “playing” requires effective staffing.And there is always the fear that behavior worsens during breaks.So the theory goes that having them in class and strictly supervised must be better. But this means that students barely have enough time to absorb what they were doing in maths before suddenly they are forced to study ancient history.And teaching staff also move through from one class to another, with hardly a rest or time to refocus. Clearly rethinking the school day could benefit everyone included.Anyway, it could also lead to better achievement in teenagers and less of a struggle for parents in the mornings. 语篇解读：本文是一篇说明文。文章讲述了上学时间延后的诸多好处，同时也提到了其中存在的一些问题。 1．How many hours do average teenagers need to sleep at least every night?
