Model Essay(范文)：
If I could invent something new, I’d invent adevice or pill that could put people to sleepimmediately and would have no side effects. The proper amount of sleep is important for ourconcentration, mental health, and physical health.
Getting enough sleep is a vital human need. For one thing, without sleep our concentration isstrongly affected. We’re easily distracted, we can’t remember things, and we don’t noticewhat’s happening around us. For example, a lot of car accidents are caused by tired drivers. When we get enough sleep, our powers of concentration are sharper. We’re more focused onwhat we’re doing. We perform better.
Mental health is also affected by lack of sleep. It’s easy to tell if people don’t get enough sleep. They’re on edge, cranky, and out of sorts. They lose their tempers easily and over-react tosituations. In fact, experiments have shown that lack of sleep over a long period of time cancause a complete mental breakdown. When we get our proper rest, we’re more alert andresponsive. Our outlook is positive, and we’re much easier to get along with.
Our physical health shows the strain of sleeplessness, too. We have less energy, andeverything seems like a major effort. Over a long period of time, we become slow andunresponsive. The wear and tear on the body from lack of sleep can be a very serious healthproblem. Every doctor will tell you that getting enough sleep is a basic factor in maintaininggood health.
Wouldn’t it be great to go to bed every night knowing you’d have no problem getting to sleep, no matter what’s going on in your life? Getting enough sleep is always going to be an importantpart of how you respond to your situation. I think this device would be very helpful to all ofus.
