Have you ever stayed up late? If so, you know that not getting enough sleep can make you tried and grumpy. Not sleeping enough sleep can also make it harder to think clearly the next day.
Sleep scientists have long known that getting a good night’s sleep is very important. It helps kids be able to do their best during the day.
A recent study shows that sleep helps improve problem-solving skills and creative(创造性的) thinking. For the study, two groups of students answered a math problem. The group that slept for eight hours solved the problem correctly more often than the group that did not get enough sleep.
While you sleep at night, your brain is busy doing its “homework”. It sorts out(整理) al

Who is there among us who hasn’t dreamed of having his or her own small (maybe , several years later , even big )business , and having wonderful freedom , both from a boss and from the time clock ; the freedom to make up our own rules for our work , and our own plans —arranging our own hours of work ? That way work would be both painless and fun. Or, so we imagine.
Well, in fact it isn’t quite as simple as that. Yes , it is true that being the boss has its satisfactions and that you can arrange your working hours freely if you own your own small business . But in those early years of starting your own business, you shouldn’t think of a free day, not to mention flying off for a month’s vacation. It is not unusual for new business owners to work seventy or eighty hours a week , and if there is a day off , that day might need to be devoted to accounting (算账).
But this negative picture doesn’t destroy the beautiful hopes. The possibility of getting something wonderful in return—both material and mental—continues to drive that large number of people who start up small businesses each year in the United States.

Our boat floated on between walls of forest. It was too thick to allow us a view of the land we were passing through, though we knew from the map that our river must from time to time be passing through chains of hills which crossed the jungle plains. Nowhere did we find a place where we could have landed: where the jungle did not actually spread right down into the river, banks of soft mud prevented us form going ashore. In any case, what would we have gained by landing? The country was full of snakes and other dangerous creatures an
d the jungle was so thick that one would be able to advance slowly, cutting one’s way with knives the whole way. So we stayed in the boat, hoping that when we reached the sea, a friendly fisherman would pick us up and take us to civilization.
As for water, there was a choice. We could drink the muddy river water, o
r die of thirst. We drank the water. Men who have just escaped from what appeared to be certain death lost all worries about such small things as diseases caused by dirty water. In fact, none of us suffered from any illness as a result.
One day we passed another village, but fortunately nobody saw us. We did not wish to risk being taken prisoners a second time: we might not be so lucky as to escape in a stolen boat again.
