注意:词数80—100(文章的开头和结尾已给出,不计入总词数),不得透露学校、姓名等任何个人信息。
Dear David,
Thanks for your interest in my invention. I’m excited to tell you about my “Smart Knowledge Glasses” for the International Youth Tech Exhibition.
They are lightweight glasses with a small camera. The main purpose is to protect your eyes while making learning more fun.

Here's how they work: when you look at an object or a text, the glasses will quickly show related information or facts on a tiny screen.

This means you can see and learn quickly and look up facts anywhere.

To make the glasses even better, I plan to add a voice-controlled feature and improve the camera's accuracy.

What do you think of my invention?



Yours,
Li Hua
