After a busy day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping makes it possible for your body to prepare itself for the next day.
There are four levels of sleep, each being a little deeper than the one before. As you sleep, your body relaxes little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to the other.
Although your mind slows down, you will dream from time to time. Scientists who study sleep point out that when you are dreaming, your eyeballs begin to move more quickly (although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement.
If you have trouble falling asleep, some people suggest breathing very slowly and very deeply. Other people believe that drinking warm milk will make you drowsy. There is also an old suggestion that counting sheep will put you to sleep.
During REM, _______.
A.you move restlessly | B.you start dreaming |
C.your mind stops working | D.your eyeballs move quickly |
The underlined word “drowsy” in the last paragraph probably means______.
A.lazy | B.sleepy |
C.relaxed | D.pleased |
One of the ways to fall asleep easily is to _______________.
A.breathe slowly and deeply | B.drink cold drinks |
C.get up and run | D.look for some sheep |
Elizabeth Freeman was born about 1742 to African American parents who were slaves. At the age of six months she was acquired, along with her sister, by John Ashley, a wealthy Massachusetts slaveholders. She became known as “Mumbet” or “Mum Bett.”
For nearly 30 years Mumbet served the Ashley family. One day, Ashley’s wife tried to strike Mumbet’s sister with a spade. Mumbet protected her sister and took the blow instead. Furious, she left the house and refused to come back. When the Ashleys tried to make her return, Mumbet consulted a lawyer, Theodore Sedgewick. With his help, Mumbet sued(起诉) for her freedom.
While serving the Ashleys, Mumbet had listened to many discussions of the new Massachusetts constitution. If the constitution said that all people were free and equal, then she thought it should apply to her. Eventually, Mumbet won her freedom---- the first slave in Massachusetts to do so under the new constitution.
Strangely enough, after the trial, the Ashleys asked Mumbet to come back and work for them as a paid employee. She declined and instead went to work for Segdewick. Mumbet died in 1829, but her legacy lived on in her many descendants(后裔). One of her great-grandchildren was W.E.B. Du Bois, one of the founders of the NAACP, and an important writer and spokesperson for African American civil rights.

It was one of those terribly hot days in Baltimore. Needless to say, it was too hot to do anything outside. But it was also scorching in our apartment. This was 1962, and I would not live in a place with an air conditioner for another ten years. So my brother and I decided to leave the apartment to find someplace indoors. He suggested we could see a movie. It was a brilliant plan.
Movie theaters were one of the few places you could sit all day and—most important —sit in air conditioning. In those days, you could buy one ticket and sit through two movies. Then, the theater would show the same two movies again. If you wanted to, you could sit through them twice. Most people did not do that, but the manager at our theater. Mr. Bellow did not mind if you did.
That particular day, my brother and I sat through both movies twice, trying to escape the heat. We bought three bags of popcorn and three sodas each. Then, we sat and watched The Music Man followed by The Man Who Shot Liberty Valance. We’d already seen the second movie once before. It had been at the theater since January, because Mr. Bellow loved anything with John Wayne in it.
We left the theater around 8, just before the evening shows began. But we returned the next day and saw the same two movies again, twice more. And we did it the next day too. Finally, on the fourth day, the heat wave broke.
Still, to this day I can sing half the songs in The Music Man and recite half of John Wayne and Jimmy Stewart’s dialogue from The Man Who Shot Liberty Valance! Those memories are some of the few I have of the heat wave of 1962. They’re really memories of the screen, not memories of my life.In which year did the author first live in a place with an air conditioner?

A.The two movies were really wonderful. |
B.They wanted to avoid the heat outside. |
C.The manager of the theater was friendly. |

One morning, Ann’s neighbor Tracy found a lost dog wandering around the local elementary school. She asked Ann if she could keep an eye on the dog. Ann said that she could watch it only for the day.
Tracy took photos of the dog and printed off 400 FOUND fliers(传单), and put them in mailboxes. Meanwhile, Ann went to the dollar store and bought some pet supplies, warning her two sons not to fall in love with the dog. At the time, Ann’s son Thomas was 10 years old, and Jack, who was recovering from a heart operation, was 21 years old.
Four days later Ann was still looking after the dog, whom they had started to call Riley. When she arrived home from work, the dog threw itself against the screen door and barked madly at her.

Riley ran over to Jack, but as soon as Ann bent over to help him the dog went silent.
“If it hadn’t come to get me, the doctor said Jack would have died,” Ann reported to a local newspaper. At this point, no one had called to claim the dog, so Ann decided to keep it.

Do you sleep well? Some people get off to sleep as soon as the head hits the pillow, but many others are not so lucky.In fact,the lack of quality sleep has become a public health issue around the world.According to the World Association of Sleep Medicine,45 percent of the world’s population suffer from sleep problems.One in eight people don’t sleep well and are easily woken.7.6 percent sleep less than 3 hours each night.Some even can not fall asleep for several days in a row.
As a basic bodily and mental need,sleep is essential for our survival.It helps us to fight diseases,strengthen our memory, perform better in work and school and improve our quality of life.Lack of sleep is known to have a significant negative influence on health,both in the short and long term.Poor sleep has been associated with obesity, weakened immune systems and even some cancers,as well as depression and anxiety.
The World Sleep Day, held on the third Friday of March,is an annual celebration of sleep to lighten the burden of sleep problems through better prevention and management of sleep disorders.
Unhealthy lifestyle may be the first to blame for sleeplessness.More and more people use cellphones and computers in bed,with many staying up until midnight.Modern technology does make our life convenient,but abuse of it ruins our health.Environmental conditions,such as temperature,noise,light,bed comfort also play an important role in one’s ability to get proper sleep.Besides,improper evening diet,like a full or an empty stomach,coffee and alcohol all contribute to sleep problems.Of course,when it comes to causing poor sleep stress from finances,family or work should never be ignored.

American cities are similar to other cities around the world.In every country, cities reflect the values of the culture.American cities are changing,just as American society is changing.
After World War II,the population of most large American cities decreased;however, the population in many Sun Belt cities increased.In the late 1940s and early 1950s,city residents became wealthier.They had more children so they needed more space.They moved out of their apartments in the city to buy their own homes.They bought houses in the suburbs(郊区).
Now things are changing,the children of the people who left the cities in the 1950s are now adults.Many, unlike their parents,want to live in the cities.They continue to move to Sun Belt cities and older ones of the Northeast and Midwest.Many young professionals are moving back into the city.They prefer the city to the suburbs because their jobs are there;or they just enjoy the excitement and possibilities that the city offers.
This population shift(迁移)is bringing problems as well as benefits.Countless poor people must leave their apartments in the city because the owners want to sell the buildings or make apartments for sale instead of for rent.In the 1950s,many poor people did not have enough money to move to the suburbs;now many of these same people do not have enough money to stay in the cities.
