The Shirt That Stops People from Slouching
The unique shirt is one of the latest inventions.A Dutch designer designed it for
people who always slouch when they sit at a desk.The shirt works in a simple
way—each time the wearer slouches,the shirt will tighten around the back.Then
the shirt will remind the wearer to sit up straight again.The designer hopes that the
shirt could help people improve their poor postures in the long run.
In my opinion,the shirt is a great invention,because it can help us keep a
good posture and work or study efficiently.It is also helpful to our health.
【点评】范文语言通顺流畅、详略得当、条理清晰地介绍了这款衬衫的
设计者、适用人群、工作原理和设计目标等方面,使读者对该衬衫有一个较

long run,in my opinion等,为文章增添许多文采。

My invention is a flying bike.
It is a special bike with two wheels and two wings. The flying bike can drive
both on the ground and in the air, and it can be used to take photos and people can
talk with it. As a very special bike, it is fast, and it is environmentallyfriendly
because it is driven by solar energy.
This is my flying bike, which is made by myself alone in my spare time. If it is
made real, I will have two improvements. I will suggest the engineer use light
irons of high quality to make the frame, and make the wheels as large as
possible.Thank you very much.
