Question

阅读下面短文,根据其内容写一篇 60 词左右的内容概要。

For many parents,making sure their children get the right amount of sleep can be stressful.This is especially true during high-pressure times such as exams when students tend to study all night for the next day.Unfortunately,it is often counterproductive(适得其反的)because with fewer hours to sleep,the teen brain doesn't get enough time to lay down what they've studied the night before.

In her groundbreaking book The Teenage Brain,neuroscientist Dr.Frances Jensen explains that bedtime isn't simply a way for the body to relax and recover after working,studying or playing a hard day. It is the glue that allows us not only to recollect our experiences but also to remember everything we've learned that day.Basically the more we learn,the more we need to sleep,which is why a good sleep is of great importance in achieving success at school.

Then how much sleep do teenagers need?There is no magic number for exactly how much sleep teenagers need,but the Austrian Centre for Education in Sleep(ACES)suggests 8 to 10 hours per day for high school adolescents.What happens if they don't get enough sleep?According to ACES,poor sleep will have all sorts of negative effects on teenagers,including rise in blood pressure,mood swings and impatient behaviours.Without adequate sleep the focus and attention drifts making it harder to receive information. The brain can no longer function to deal with information properly and access previously learned information.

So,how can parents help?If you think your child needs more sleep,try making gradual changes to their sleeping habits.Small increases have been shown to be effective in changing sleep patterns.And remember your children are going through a period of their lives when their brains and bodies are going through a lot of changes.Not only is your job to help make changes,it's also to ride the wave with them.It may not be easy,but they will thank you for it eventually.

Answer

Nowadays parents find it hard for their children to get adequate sleep despite its necessity for efficient learning. Generally, more learning requires more sleep to guarantee learning success. Experts suggest teenagers sleep 8 to 10 hours a day so as not to be negatively influenced. Therefore, parents can help children change their sleep patterns progressively through the hard time together.

【解析】

本篇书面表达是概要写作。阅读所给材料可知，文章谈了三个要点：提高学习效率就要保证孩子们的睡眠，因为学习需要更多的睡眠来保证学习的成功；专家建议青少年每天要睡8-10个小时才能不对他们产生不良影响；父母要克服困难帮助孩子们来改变他们的睡眠模式。

1．细读原文。首先要仔细阅读短文，掌握文章主旨和结构，明确各段的大意。应包括原文中的主要事实，略去不必要的细节。弄清要求。概要写作是写全文概要，不是写某一部分的概要，或者就某些问题写出要点。

2．列出原文要点。分析原文的内容和结构，将内容分项扼要表述并注意在结构上的顺序。在此基础上选出与文章主题密切相关的部分。安排好篇幅的比例，概要应同原文保持协调，即用较多的文字写重要内容，用较少的文字写次要内容。

本篇文章要点是：第一段和第二段：睡眠的量会影响学习效率，为什么会影响；第三段：青少年每日需要的睡眠量；第四段：父母有责任帮助孩子们改变他们的睡眼模式。

3．注意要点之间的衔接，要用适当的关联词语贯通全文，切忌只简单地写出一些互不相干的句子，但也不要每两句之间都加关联词语，以免显得生硬。

4．不排斥用原文的某些词句，但不要照搬原文的句子，如果不能完全用自己的话语表达，至少对原文句子做一些同义词替换，如果结构上也能有一些转换会更好。

5．计算词数，看是否符合规定的词数要求。
