Sleep is divided into periods of so-called REM sleep, characterized by rapid eye movements and dreaming, and longer periods of non-REM sleep.
41 kind of sleep is at all well-understood, but REM sleep is
42 to serve some restorative function of the brain. The purpose of non-REM sleep is even more
43 . The new experiments, such as these
44 for the first time at a recent meeting of the Society for Sleep Research in Minneapolis, suggest fascinating explanations
45 of non-REM sleep.
For example, it has long been known that total sleep
46 is 100 percent fatal to rats, yet,
47 examination of the dead bodies, the animals look completely normal. A research has now
48 the mystery of why the animals die. The rats

50 their immune systems-the self-protecting mechanism against diseases-had crashed.

Cloze Test 5 Until recently most historians spoke very critically of the Industrial Revolution. They
41 that in the long run industrialization greatly raised the standard of living for the
42 man. But they insisted that its
43 results during the period from 1750 to 1850 were widespread poverty and misery for the
44 of the English population.
45 contrast, they saw in the preceding hundred years from 1650 to1750, when England was still a
46 agricultural country, a period of great abundance and prosperity.
The view,
47 , is generally thought to be wrong. Specialists
48 history and economics, have
49 two things: that the period from 1650 to 1750 was
50 by great poverty, and that industrialization certainly did not worsen and may have actually improved the conditions for the majority of the populace.
