台湾籍旅美老师今天交给我们的句子是：

And don't set alarms every half-hour, you're not gradually waking yourself up. You're interrupting and restarting your sleep over and over again. I'm guilty of this, so are many of you.
别把闹钟设成每30分钟就响一次，你这样不是把自己慢慢叫醒。你只是一直重复打断又重启你的睡眠状态。我承认我自己也在犯这样的错，跟你们大部分的人一样。

学习重点：

1.alarm 警报
alarm (n.) 警报
alarming (adj.) 惊人的

2.gradually 渐渐地
gradually (adv.) 渐渐地

3.wake 醒来
wake (v.) 醒来
awake (v.) 唤醒

4.interrupt 中断
interrupt (v.) 中断
interruption (n.) 终止

5.guilty 罪恶的
guilty (adj.) 罪恶的
guilt (n.) 罪恶
