After a 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 enables 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 muscles relax 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, from time to time you will dream. Scientists who study sleep state that when dreaming occurs your eyeballs begin to move 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 recommend breathing very slowly and very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion that counting sheep will put you to sleep.A good title for this passage is _______.

The island Fiji has always been around me in my life. My parents met in Fiji when my father was a teacher as a Peace Corps volunteer and my mother a student. They taught me about its people, culture, foods and religious beliefs.
At the age of two, I made my first trip across the Pacific Ocean to Fiji. My mother and I made that trip unexpectedly because my grandma was ill and longed to see her American granddaughter. Although I have few memories of that first trip, I do remember grandma braiding(编辫子) my hair every day. The brush gliding through my hair is a feeling I will treasure forever because she passed away soon. I returned to America when I was five years old. This time I had a brother, Martin, who was two.
I resisted my third trip to Fiji when I was 15, being a teenager who did not want to spend the summer away from friends. It was this trip, however, that made me realize that Fiji is not just a place to visit but a part of who I am. The smells and sounds and sights came back to me, but the best part was getting to know my relatives.
Vishal was one cousin I quickly bonded with(与…合拍). Born two days before me, I had only known him through pictures before. Though raised oceans apart in different cultures, we talked and laughed about everything from American sports to Fijian dancing. I was able to form close ties with all my cousins, and when I talk about them now, it’s as if I have known them my whole life. Spending time with them helped me understand the traditions and values my mother grew up with. Hospitality (热情) and care and respect for family members are central values in Fijian culture.
I truly enjoyed learning about my roots during this trip. Fuji is just like a second home, and I will never forget the time I have spent there.From the passage, we can learn that ______________________.
A. My Trips to Fiji |
B.Discovering My Fijian Origins |
C.My Understanding of Fijian Culture |
D.My Memories of Fiji |
After their 15-year-old dog Bailey died in 2007, Ron and his wife, Ann, looked for months to find the right new pet. “I love dogs,” says Ron, a worker at a health club in Waukesha, Wisconsin. “I can’t imagine not having one.”
Finally, the couple spotted a young dog at the Humane Society in Milwaukee. His name was Oscar. “He was very attractive,” says Ron, 65. Oscar quickly made himself at home, sleeping on his new owners’ bed at night.
A diabetic(糖尿病人) for 25 years, Ron faithfully took his medicine four times a day and generally had no problems. But on March 17, at about 3 a.m., he got out of bed to use the bathroom. Suddenly, he fell down to the floor. “I must have taken the wrong amount of medicine before I went to sleep, because my blood sugar was dangerously low,” he says.
“Normally, Oscar is very quiet and well-behaved,” says Ron. “But when I hit the floor, he let out sounds like a wild animal.”
“Honestly, it sounded like the dog from hell,” says Ann, who was awakened by the sound.” I didn’t know what the sound was. Then I saw my husband lying on the bathroom floor. He was cold.” She ran for the phone and called an ambulance.
Ron spent several hours in the hospital. By 6:30a.m., he was well enough to go home. “You would never suspect Oscar of any heroism.” says his grateful owner. “He’s a wonderful little guy. We are lucky enough to own him.”
Even before Oscar’s heroic action, the couple had given their pet a new nickname(昵称). “We felt the name Oscar wasn’t good enough,” says Ron, “so sometimes we call him Eduardo”—more suitable, they think, for their dog.What was Ann doing when Ron went to the bathroom?
A.She was sleeping. |
B.She was watching TV. |
C.She was taking care of Oscar. |
D.She was talking with someone on the phone. |
Why did Ron fell onto the floor in the bathroom?
Keeping a busy social life among lots of friends may keep people thinner than spending hours doing some exercises, according to scientists. They say that socialising and meeting with friends help increase levels of brown fat in the body which burns calories(卡路里)to produce heat.
Living in an exciting social environment was found to reduce fat in mice's belly by half over four weeks, even if they ate more. US researchers say that social excitement aids weight loss by turning white fat into brown. White fat stores calories and makes us fatter, while brown burns energy to produce heat. Turning white fat into brown is extremely difficult,normally
requiring long- term stay in cold conditions or exciting part of the body's nervous system.
However, scientists from Ohio State University now think that having a busy social life is an even more effective way of changing white fat into brown. The team came up with their theory by studying the effects of various living environments on mice. Those, who lived alongside a greater number of mice, had more space and toys to excite themselves and then lost far more weight over the course of the study than their “couch potato" fellows.
Study author, Dr Matthew During, whose team's findings appear in the journal Cell Metabolism, said, "I'm still amazed at the degree of fat loss that occurs." Explaining how new technology had threatened face-to-face socialising, he added, "It's not just a sedentary(久坐 的)lifestyle and high calorie foods, but an increasing lack of social activities." Co-author Dr Lei Cao said,"Loneliness is a potential factor for cancer and death; it's equal to cigarette smoking to a certain extent. Social activities are very vital.,,What information can we get from the first two paragraphs?

We can conclude from the text that _______.
A.the fat in mice's belly was reduced because of the relaxing environment |
B.a sedentary lifestyle and high calories foods influence people's social life |

“Whatever”,totally tops most annoying word in the poll(民意测验).So, you know, it is what it is, but Americans are totally annoyed by the use of “whatever,,in conversations. The popular term of indifference(不感兴趣)was found most annoying in conversations by 47 percent of the Americans surveyed in a Marist College poll on Wednesday.
"Whatever" easily beat out “you know," which especially annoyed a quarter of interviewers. The other annoying expressions were "anyway"(at 7 percent), “it is what it is’,(11percent) and “at the end of the day”(2 percent).
"Whatever" is an expression with staying power. It left everyone a deep impression in the song by Nirvana (“oh well, whatever, never mind”)in 1991 and was popularized by the Valley Girls in the film “Clueless”,later that decade. It is still commonly used, often by younger people.
It can be a common argument-ender or a signal of indifference. And it can really be annoying. The poll found '"whatever" to be consistently(始终地)disliked by Americans regardless of their race, sex, age, income or where they live.
“It doesn't surprise me because ‘whatever,is in a special class, probably,,,said Michael Adams, author of “Slang(俚语)~The People's Poetry" and an associate professor of English at Indiana University. "It's a word that 一 and it depends on how a speaker uses it 一 can suggest being not worthy of attention or respect.’,Adams, who didn't take part in the poll and is not annoyed by "whatever," points out that its use is not always negative. “It can also be used in place of other neutral(中性的)phrases that have fallen out of favor, like ‘six of one, half dozen of the other,.” he said. However, he also noted that the negative meaning of the word might explain why “whatever,was judged more annoying than the ever-popular "you know”.Which tops second among the annoying expression according to the passage?'
A.Whatever. | B.You know. | C.Anyway. | D.It is what it is. |
What can we know about the word "whatever"?
A.It became popular because of Nirvana. |
B.It can be commonly used at the beginning of an agreement. |
C.Old people like it while young people don't. |
D.Almost half of the Americans surveyed disliked it. |
In Adams' opinion, the reason why “whatever”,was judged more annoying may be that . _______
A.most of the people don't like it |
B.it can be used in place of other neutral phrases |
C.it carries certain negative meaning sometimes |
D.the poor don't like it |
Which of the following statements is true?
A.Adams is not only a writer but also a professor. |
B.“Whatever” is a signal of concern. |
C.Adams is angry at the word “whatever” |
D."Whatever" will be replaced by "You know”. |
Have you ever heard of Paynes Prairie(大草原)? It is one of the most important natural and historical areas in Florida. Paynes Prairie is located near Gainesville. It is large, 21,000 acres. This protected land is called a reserve, which is managed by the Florida Park Service.
The Paynes Prairie basin was formed when limestone(石灰石)broke down and the ground settled. It is covered by wet prairie plants. There are areas of open water. During brief periods it was flooded enough to be considered a lake. Except for that, the basin has changed little through time.
Man has lived on Paynes Prairie a very long time. He lived there as far back as 10,000 B.C.. At one time, the Seminoles lived there. The prairie is thought to have been named after King Payne, a Seminole chief. During the late 1600s, the largest farm where cattle are fed in Florida was on Paynes.
William Bartram who lived 200 years ago visited Paynes Praire in 1774. Bartram was the first person who described nature through personal experiences as well as scientific observations. At that time he called Paynes Prairie the “great Alachua Savannah". Most of the animal life, which Bartram described, is still here. A large number of animals live here in winter. The variety of animals is increased by the presence of pine flat woods, wetlands and ponds.
The Paynes Prairie Reserve State Park is open all year round. The Florida Park Service works hard so that the park will appear as it did in the past. It offers many opportunities for entertainment. In the park you can camp and picnic. You can hike and bike. You can boat and fish. You can ride on horses.
