  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 49 bacterial infections of the blood, 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.
