年轻时取得成就，如果你足够长命，那你最好努力争取在拿奖后的日子中也再争取拿多两三个有影响力的奖，那么就至少能塞一塞世人、后人的刁嘴，让他们至少拿不出证据说你只有一个成就，日后就毫不进取，毫无成就，只有那么一个可怜巴巴的奖。

Each 8031 microcomputer contains a high speed full duplex (means you can simultaneously use the same port for both transmitting and receiving purposes) serial port which is software configurable in 4 basic modes: 8 bit UART; 9 bit UART; Interprocessor Communications link or as shift register I/O expander. For the standard serial communication facility, 8031 can be programmed for UART operations and can be connected with regular personal computers, teletype writers, modem at data rates between 122 bauds and 31 kilobauds.

每8031微机包含高速全双工（意味着你可以同时使用相同的端口都发射和接收的目的）的串口是软件配置在4基本模式： 8位异步； 9位异步；整合通信链路或移我登记/海外扩张为标准的串行通信设备， 8031可以编程为异步操作，可与普通的个人电脑， teletype作家，在现代数据传输率之间的122波特和31 kilobauds 。

Since American Bobtails are very friendly and a bit nosy, they are prone to get into quite a bit of mischief if they are unsupervised and become bored.
