My 2nd english lesson

My teacher has been changed. I don't need translate story. In this lesson, I interpreted Object-Oriented to my partner. I don't prepare before. I said, the cat inherited from animal, and the dog is also inherited from animal. The cat eat fish, and the dog eat bone. The cat has 4 legs and the dog has 4 legs. Sorry, I think, I made a wrong example, they are both 4 legs. I also interpreted how to write Object-Oriented program by C program language.

btw0: msp430反汇编写好了，接下来要实现指令了。

btw0 english version: The disassembler for MSP430 has done. I'll realize instructions next.
