阅读理解 A typical school day in the UK starts around 8:30 am. This is often even earlier elsewhere in the world, with students sitting down to their first lesson at 7:30 am in the US. The average teenager ideally needs eight to nine hours' sleep each night, but in reality a lot of teenagers struggle to get this much. A lot of the 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 managed 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.

It will add to the teacher's pressure. B . It has always been there for 25 years. C . Parents may support it. D . It benefits the students only. 答案： A D C
