Here, sleep experts clear up some of the biggest misunderstandings about sleep they see with their patients, which could weaken your ability to have a night of good sleep.

Myth: {#blank#}1{#/blank#}

    The latest research shows that the right amount of sleep may vary from person to person and should leave you feeling energized the next day. I'm a sleep doctor. Take myself for example. {#blank#}2{#/blank#}.

Myth: Don't fall asleep with the TV on.

    I've cured more people suffering from sleep problems than you can imagine by telling  people it's OK to fall asleep with the TV on. {#blank#}3{#/blank#}Control the watching time so it doesn't affect your sleep later in the night.

Myth: You can catch up on lost sleep on the weekend.

    {#blank#}4{#/blank#} A Harvard study found that even if you sleep for an extra 10 hours on the weekend to make up for only sleeping six hours a night for two weeks, those extra hours won't improve  your reaction times or ability to focus. Plus, sleeping late throws off your biological clock, which can lead to obesity, diabetes, and heart disease.

Myth: Alcohol can help you rest easy.

    {#blank#}5{#/blank#} Alcohol may relax you so you nod off quicker, but studies show you'll wake up more and get less of deep sleep you need to feel rested.

    The World Health Organization, the WHO, says the disease Ebola is spreading in West Africa. The situation frightens both local citizens and travelers.

    There is no vaccine(疫苗) or special treatment. And the fatality(致命) rate is very high. That rate represents the number of people who get sick from Ebola and then die. Ebola can kill up to 90 percent of those infected.

    It is difficult to stop Ebola from spreading. It moves easily from person to person. The disease strikes its victims through direct contact with the blood or other liquid from the body of an infected person. For that reason Ebola patients must be kept away from other people. The bodies of victims still contain the virus days after they die. Local traditions and burial customs also make the sickness hard to control. Doctors say it is important to identify an Ebola case early to prevent others from becoming infected. Patients suffer from high body temperature, bleeding and so on.

    Only a few prevention measures exist. The Centers for Disease Control and Prevention in the US, the CDC, and the WHO suggest staying away from countries with confirmed(被证实的) Ebola cases. People at increased threat include those working in animal research, health care workers and others caring for patients in the community.

    As of July 15, 2014, the WHO says Ebola killed 68 people in Guinea, Liberia, and Sierra Leone, the three countries where the disease has been confirmed. A patient in Ghana was suspected of having Ebola, but tests did not show the sickness. Ghanaian observers say the man has since died from unknown causes. The victim was an American citizen.

    In the past, cases of Ebola have been confirmed in the Republic of the Congo, Democratic Republic of the Congo, Gabon, Sudan, and Uganda.

    Doctors advise careful protective measures if you must go to an area where Ebola exists.

    Wash your hands often. If soap and water are not available, use a hand sanitizer（消毒杀菌剂）—or cleaner —containing at least 60 percent alcohol. Avoid eating monkeys or other wild meat. Stay away from mines and places where bats and other rodents may live.

    If Ebola has been identified directly around you, the CDC and WHO strongly suggest wearing protective clothing. Cover your face and hands. Goggles(护目镜) can help protect the eyes. Try to remove Ebola germs (细菌) with cleaners that fight infection.

    Louise Blanchard Bethune showed early promise in math. But Louise did not go to school. Instead, her father taught her at home until she was 11 years old. She also discovered a skill for planning houses. It developed into a lifelong interest in architecture and a place in history as the first professional female architect in the United States.

    After graduating from high school in 1874, Louise traveled and studied. She hoped to prepare herself to attend the new architecture school at Cornell University. But then Buffalo's leading architectural firm of Richard A. Waite and F.W. Caulkins offered her a job. She knew that architects gained their training from practical experience, not from school. She took the job.

Louise worked there as an assistant, 10 hours a day for five years. She learned —-and mastered—-drawing and architectural design. She also met her husband, Robert A. Bethune. Their new firm, R.A. and LBethune, opened in October 1881.

    Bethune appeared to be the strength of the business. At the turn of the 20th century, the city of Buffalo was rapidly expanding to meet the demands of growing industry. The firm received tasks to build hundreds of structures throughout western New York. The firm designed lots of schools, apartment buildings, department stores, churches and factories.

    Bethune believed that being an architect meant being an artist, a scientist and a business person. She made a point of advocating for women in the profession. She became a member of the Western Association of Architects(WAA) in 1885. In 1888, she was the first woman to join the American Institute of Architects(AIA). Besides, Bethune took a firm stand on equal treatment for women architects. She insisted on equal pay for equal work.

    Bethune left almost no papers or letters, and few people recognize her name today. But her legacy remains in the foothold she established for women in the field of architecture. She started her own firm and enjoyed a successful career.

Following the old saying of "early to bed and early to rise" I used to go to bed at 10 pm and get up early at 6 am to get ready for school. But that day, as it was cloudy, I continued to sleep for long, thinking it to be the early hours of the day.

Suddenly, I heard a loud voice which startled me up and made me sit upright. It was my mother's voice who was knocking and shouting, "Get up honey. It's 6:45 am already! You are getting late for school!" As it was a cloudy day, I hadn't realized that it was almost 7 and continued dozing for long!

But thank fully that day our pick-up person who generally used to come at 6:50 am got late due to the showers and arrived just in the nick of time when I was ready. By the time we reached school it was a quarter to eight and the drizzle from previous night had finally stopped. I entered the classroom fearing the teacher's anger, but saw only a few students had made it to school. Therefore, the principal declared a holiday. "Hurray!" We all cheered in a chorus at the unexpected holiday and decided to walk back home.

    As it had been continuously drizzling since the previous night there was water all over the place and the roads were impassable. Just then, at a distance my sister and I saw little kids playing in knee-deep water in the streets which touched the play button in us. We quickly approached them and merrily jumped and hopped in the pool of water with them. With shoes in our hands we continued parading on the muddy streets. We were thrilled and our hearts were filled with joy at the sight of the green and fresh leaves on the trees; the frogs drew our attention as we tried to catch butterflies.

    We finally reached home busily playing and laughing with mud-spattered uniforms and shoes. We hurriedly changed our outfits, washed up and sat watching TV with a bowl of hot soup! No doubt, I thoroughly enjoyed this day and secretly prayed for many such days in the future! To this day when it pours, the memories of that eventful rainy day bring a smile on my face!

    Tencent announced yesterday that it will limit the daily time for youngsters to play its popular King of Glory game after parents and schools in Shanghai and other areas complained their children had become addicted to playing it.

    From tomorrow, children younger than 12 will only be allowed to play the game for a maximum(最大值) of one hour a day, and after 9 pm, they will be banned from logging into it, said Tencent. Those older than 12 will be able to play a maximum two hours a day.

    The game system will remind players the time they have been playing and young players will be forced to log out when the time is up.

    Tencent claimed these were the strictest measures in China's game industry to prevent addiction and the company expected they would ease parents' anxiety.

    The company also said it had updated its system for parents to keep tabs on their children using its games.

    Since February, parents can receive messages when children log in and spend money on the game after they connect children's game accounts with their mobile phone numbers.

    Now, parents can connect phones, tablets or computers that their children use to play games, so that they can keep an eye on the children even if they have several game accounts, Tencent said.

    Song Zhe, a father of a Shanghai high school student, welcomed the measures but was not sure if they would be sufficiently effective. "I like the system that could lock up the devices as children can register many accounts," he said, "but children are so clever that they can always think out counter measures."

    We spend a great amount of time listening to music. Most college students listen to music at least three or four times a week, and more than 50 percent of them go to at least one concert per year.

    According to new research, we may be born liking music, because human beings are born to find certain combinations of sounds attractive. For example, young children can recognize a familiar Song even when its key is changed. Similarly, they respond with more emotions to their mothers' singing than to their mothers' speech. Careful analysis of mothers' child-directed songs indicates that each mother's songs remain stable from one "performance" to the next, and this may encourage children's engagement with the songs.

    Research with adults suggests that music catches our attention by activating(激活) brain pathways that are most suited to processing music than to processing other kinds of sound. Specifically, music appreciation relies on the auditory cortex(听觉皮层) on the right side of the brain, which is specialized to process sound that characterizes music-in contrast to the left auditory cortex, which processes the stop-and-start bursts of sound that characterize speech.

    Although some Psychologists remain skeptical about whether music may have powerful effects on our thinking, a number of studies have shown that listening to music can increase people's spatial reasoning abilities Furthermore, It is clear that music can greatly influence our emotions. Personally significant music activates areas of the brain associated with pleasure and reward, the same areas that are activated by sex and good food.

    Researchers do not agree about how humans' abilities to process and enjoy music have come into being. Anyway, the next time you enjoy listening to a piece of music, remember that the most complex pieces of audio equipment are the ones between your headphones.
