| When you first drift off into slumber,
your eyes will roll about a bit, your temperature will drop slightly, your
muscles will relax, and your breathing will become quite regular. Your brain
waves slow down a bit, with the alpha rhythm predominating for the first few
minutes. This is the first stage of sleep. For the next 30 minutes or so, you
will drift down through Stage 2 and Stage 3. The lower your stage of sleep, the
slower your brain waves will be. About 40-60 minutes after you lose
consciousness, you will reach the last stage. Your brain waves will show the
delta rhythm. You may think that you stay at this deep stage all the rest of the
night, but that turns out not to be the case. About 80 minutes after you fall
into slumber, your activity cycle will increase slightly. The delta rhythm will
disappear, to be replaced by the activity pattern of brain A. is one stage B. are two stages C. are six stages D. are four stages [简答题]While you should always keep your options open to compromise, you should also be sure to target exactly what you want in a job.
