[2024烟台蓬莱区中考二模]Teenagers need eight to ten hours of sleep per night. However, in adolescence(青春期), changes to the body's sleep cycle make it difficult for teens to fall asleep early. Many cannot fall asleep until 10:30 p.m. or even later and most of them will feel sleepy if they have to get up too early.
Scientists recommend that both middle and high schools begin no earlier than 8:30 a.m. Later school start times support the natural needs of teenagers and increase their sleeping time.
Here are some other benefits of later school start times:
More time for a healthy breakfast
When running late in the morning, students are likely to go without breakfast. With an empty stomach, one finds it difficult to focus(集中) in class. When they are always in a hurry, students may form unhealthy eating habits.
With extra time before going to school, students can eat a well — balanced breakfast and focus more on learning.
Fewer behavioral(行为的) problems
Teens experience mood changes as a common result of this special period of life. Less sleep may cause worries, stress and unhappiness.
When they get enough sleep, students are calm and peaceful and their moods do not change suddenly. They're less likely to feel worried, unhappy or angry. For parents, children with more sleep are easier to live with.
Better performance(表现) in study
Sleep loss hurts attention, memory and brain development. Students with less sleep have difficulty paying attention in class and are likely to have lower grades. Students with enough sleep can be more energetic during the day and more willing to learn. They are also less likely to fall asleep in class and more able to understand what they learn.
In conclusion, starting school later helps students get a better night's sleep. It improves their chances of eating, behaving and performing better.

技巧点拨
推断作者写作文章的意图时，要综合考虑文章的主旨和文章的体裁。
(1)通常情况下，写作意图题和文章主旨密切相关，我们可以通过文章的首尾段和各段的首尾句来抓住文章的主旨，从而推断出作者写作文章的意图。
(2)作者的写作意图还和文章的体裁紧密相关。①议论文通常是要通过论证使读者接受或赞同某一观点；②说明文通常是为读者提出某种建议、劝告或描述某种现象，从而引起读者的注意；③记叙文一般是通过描述具体事件来告诉读者一个故事或者作者对于某件事情的感受和得到的启示；④应用文一般的目的是进行宣传，从而引起读者的兴趣。
