【答案】Ladies and gentlemen，
If I could invent something new，I'd invent a device that could put people to sleep immediately and would have no side effects，whose name is Sleeping-helper.The proper amount of sleep is important for our concentration，mental health，and physical health.
Getting enough sleep is a vital human need.For one thing，without sleep our concentration is strongly affected.Mental health is also affected by lack of sleep.They lose their tempers easily and over-react to situations.
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 important part of how you respond to your situation.I think this device would be very helpful to all of us.
Thank you very much for your listening.
