Directions: Read the following passage. Complete the diagram by using the information from the passage.

Write NO MORE THAN THREE WORDS for each answer.

Rest is critical to life and work and a positive attitude towards rest needs to be maintained, for enough rest is significant to our body and mind while a lack of adequate rest, as well as misleading attitudes to rest, will do great harm to our health.

Rest is vital to our ability to function at our best. Recent news stories report that scientists are learning surprising things about the importance of sleep. There is enough evidence suggesting that rest will refresh us, enabling our body and mind to work efficiently. Besides, rest is important for more than that; it is helpful in setting appropriate goals and deciding what goals to attain first. Those who are caught up in extremely busy lives lack the time to think about what they are doing and to make objective decisions, which blocks the maximization of their potential.  

On the contrary, lack of adequate rest damages brain function, so much so that sleep experts have been able to measure drops in IQ in patients who are short of sleep. Other studies have presented a negative effect on body movements in sleep-wanting subjects. It should not, therefore, be a surprise that the California Highway Patrol has stated that sleep-wanting drivers are as great a threat to road safety as are drunk drivers.

However, rest is widely misunderstood by some people. Instead of sleep, they go to pubs and clubs and claim that this kind of entertaining is rest. For example, what they call social drinking or having a smoke with friends. Nowadays, the economy forces people to drink and gamble for the sake of the circles one moves in. This is what fools claim thoughtlessly that it’s restful. The truth is that rest means not using our labor both physically and mentally, even spiritually.

We need to rest correctly and sufficiently; otherwise, tiredness and illness will occur. Without sufficient rest, good work is impossible.Rest is critical; it is not an end in itself.
