If you left your book on the table overnight, you would find the following morning that it was still exactly where you had left it, provided nobody had moved it. If a ball is made to roll on a very smooth surface, it will roll a long distance unless something stops it or changes its direction. This tendency of an object to remain at rest unless something moves it and to continue moving unless something stops it is known as the Law of Inertia.
The following examples show the truth of this law.
a. Put a table-cloth on a table and arrange a pile of books on it. Hold one edge of the table-cloth and pull it quickly. The table-cloth will come off, leaving the pile of books undisturbed.

[不定项选择题]共用题干
Are You Getting Enough Sleep?
What happens if you don't get enough sleep? Randy Gardner,a high school student in the United
States,wanted to find out. He designed an experiment on the effects of sleeplessness for a school science
project. With doctors watching him carefully,Gardner stayed awake for 264 hours and 12 minutes.That's
eleven days and nights without sleep!
What effect did sleeplessness have on Gardner? After 24 hours without sleep,Gardner started having
trouble reading and watching television. The words and pictures were too blurry（模糊）.By the third day,
he was having trouble doing things with
his hands. By the fourth day, Gardner was hallucinating（产生幻
觉）.For example,when he saw a street sign,he thought it was a person.He also imagined he was a famous
football player. Over the next few days, Gardner's speech became so slurred（不清楚）that people couldn't
understand him.He also had trouble remembering things.By the eleventh day, Gardner couldn't pass a
counting test.In the middle of the test he simply stopped counting.He couldn't remember what he
was doing.
When Gardner finally went to bed,he slept for 14 hours and 45 minutes.The second night he slept for
twelve hours,the third night he slept for ten and one-half hours,and by the fourth night,he had returned to
his normal sleep schedule.
Even though Gardner recovered quickly,scientists believe that going without sleep can be dangerous.
They say that people should not repeat Randy's experiment. Tests on white rats have shown how serious
sleeplessness can be. After a few weeks without sleep, the rats started losing their fur（皮毛）.And even
though the rats ate more food than usual,they lost weight.Eventually the rats died.
During your lifetime,you will probably spend 25 years or more sleeping.But why?What is the purpose
of sleep? Surprisingly,scientists don't know for sure.Some scientists think we sleep in order to
replenish（补充）brain cells. Other scientists think that sleep helps the body to grow and to relieve stress.
Whatever the reason,we know that it is important to get enough sleep.
Going without sleep is not dangerous for white rats.
A.Right
B.Wrong
C.Not mentioned
