As many scientific surveys said, sleep takes up one - third (改：one-third) of a person's life. Getting enough sleep can help cells fix our body. It's very clear that sleep is important to us.（段评：本段作为开头,点明了睡眠的重要性,观点明确！但在表达方面可以更加丰富: 1. 词汇选择:'fix'在此处不够准确,修改版使用了'heal'(课标范围内词汇),更符合'修复身体'的语境。 2. 句式单调:原文多为简单句,修改版使用了'which'引导的限制性定语从句(初中课标范围内),使表达更流畅。 3. 逻辑连接:添加了'As many scientific surveys show'替代'As many scientific surveys said',更符合客观事实的表达习惯。修改版：As many scientific surveys show,sleep takes up one-third of a person's life. Getting enough sleep can help cells heal our body,which makes it clear that sleep is important to us.）

I used to have sleeping problems about a year ago. I usually woke up at night and was hard to fall asleep (改：found it hard to fall asleep) again. Nightmares also bothered me.（段评：本段描述了过去的睡眠问题,内容具体！但存在语法错误: 1. 主谓不一致:'was hard to fall asleep'应改为'found it hard to fall asleep',原句缺少主语。 2. 时态一致:'used to have'与'usually woke up'时态一致,但'was hard'结构错误,修改后更符合英语表达习惯。修改版：I used to have sleeping problems about a year ago. I usually woke up at night and found it hard to fall asleep again. Nightmares also bothered me.）

To solve these terrible problems, I started to make some changes. For example, I avoided listening to music before sleeping. And I did more exercise. What's more, drinking less coffee but more milk improved this problem too. It was very glad to me (改：I was very glad) that the measures had solved my problems.（段评：本段讲述了解决睡眠问题的方法,逻辑清晰！但存在语法错误和表达问题: 1. 主谓不一致:'It was very glad to me'应改为'I was very glad',原句主语错误。 2. 词汇重复:'improved this problem'表达不够准确,修改为'helped improve my sleep'更自然。 3. 逻辑连接:添加了'First'、'Second'等连接词,使步骤更清晰。修改版：To solve these terrible problems,I started to make some changes.

From my experience, dealing with sleeping problems doesn't only make me more energetic but also make me stronger (改：makes me stronger) . Now I suggest others to sleep (改：suggest that others sleep) more and better. Since sleeping is so significant to us, let's be a sleep keeper.（段评：本段总结了经验并提出建议,升华了主题！但存在语法错误: 1. 主谓不一致:'doesn't only make...but also make'应改为'doesn't only make...but also makes',保持动词形式一致。 2. 词汇选择:'suggest others to sleep'应改为'suggest that others sleep',符合'suggest'的用法(初中课标范围内)。 3. 表达优化:'be a sleep keeper'改为'develop good sleep habits'更具体,符合语境。修改版：From my experience,dealing with sleeping problems doesn't only make me more energetic but also makes me stronger. Now I suggest that others get more and better sleep. Since sleep is so significant to us,let's develop good sleep habits.）
