未来的笔 The Future Pen

I love to collect the pens with all kinds of cartoons. I use pens every day. When I buy the pen that has colorful pictures, I will be very excited. In the future, I want to own a pen,which can change the color and pictures. Then when I use it, I feel like owning the new pen. 
我喜欢收集各种各样的卡通笔。我每天都要用支笔，所以当我买一支有彩色图片的笔时，我会非常兴奋。未来，我想拥有一支可以改变颜色和图片的笔，这样我用笔的时候，就犹如拥有了一支新的笔。
