Tea and coffee are two of the most widely consumed drinks in the United States. With popularity and interest in tea continuing to grow in recent years, many consumers have recently considered making the switch from coffee to tea, if they have not done so already. All the buzz surrounding tea and coffee may have you wondering, what are the differences? As it turns out, the differences are many and varied.

In the US, interest in tea ranges from coast to coast with the highest in Hawaii and California but stretching to the eastern states of Vermont and New York. On the other hand, the highest interest in coffee tends to be concentrated more in the north and western regions(地区), with the highest search volumes appearing in the states of Hawaii, Washington and Minnesota.

Differences between tea and coffee also vary in origin and production. All tea comes from the harvested leaves of the Camellia sinensis plant, while there are about 60 different species of coffee

plants. Production of tea is quicker and more efficient: Camellia sinensis plants only need to grow for three years before they are ready to process; coffee plants take up to five years.

Perhaps the most concerning issue consumers have when considering making the switch to tea is the question of caffeine. The good news is, when it comes to tea and caffeine, there is something for everyone. Unlike coffee, which typically only comes in decaffeinated and regular, there are several varieties of tea available, based on caffeine preference.

From herbal teas that are naturally free of caffeine, to high quality green and black teas that offer less than half the caffeine of coffee, to high caffeine teas such as our specially formulated HiCAF® blends that contain slightly more caffeine than a cup of coffee, there is a variety sure to suit your needs. As an added bonus, the lower acidity levels in tea tend to be gentler on the stomach for a more comforting pick-me-up.

So what is the answer, coffee or tea? If you are looking for the most healthful benefit possible, tea is probably the winner. They say a picture is worth a thousand words. If, like many Americans, the rising popularity in tea has your interest piqued, the images below will help to clearly spell out the differences between tea and coffee.

Can eating a chocolate bar every day really prevent age-related memory loss? No. But a new research shows that large amounts of flavones（黄酮）, something found in cocoa, tea and some kinds of vegetables, may improve age-related memory failure.

Dr. Scott Small is a professor of neurology (神经病学) at Columbia University in New York City. He is the lead writer of a research paper describing the effects of cocoa flavones on brain activity. His study involved 37 volunteers aged between 50 and 69. Researchers gave them a high-level flavones drink made from cocoa beans or a low-level flavones drink. For a period of three months, some subjects got 900 milligrams of flavones a day. The others got 10 milligrams of flavones each day. Brain imaging and memory tests were given to each study subject before and after the study. Dr. Small says that the subjects who had the high-level flavones drink showed much improvement on memory tests.

The researchers warn that more work is needed to be done because this study was performed only on a small group. Dr. Joann Manson is the lead researcher of a four-year study involving 18,000 adults. This study will use flavones capsule. The study subjects will be divided into two groups and will take two pills per day . The capsules used will all look the same. But one group’s capsules will contain flavones, while the other group will take capsules made of an inactive substance, or placebo

Dr. Manson says it’s not necessary for people to start eating more chocolate, because a person would have to eat a huge amount of chocolate to get the same level of flavones given to the rest subjects. He adds many manufacturers have planned to remove the flavones from their chocolate products. Similarly, Dr. Manson says a cocoa-based flavones extract may be developed in the future But he says that more studies are needed to see how much flavones is good for our health.

The sharing economy has grown in recent years to include everything from apartmentˈ sharing to car sharing to community tool sharing. Since 2009, a new form of sharing economy has been emerging in neighborhoods throughout the US and around the world-Little Free Library. The libraries are boxes placed in neighborhoods from which residents can withdraw and deposit books. Little Free Libraries come in all shapes and sizes. Some libraries also have themes, focusing on books for children, adults, or tour guides.
In 2009. Tod Bol built the first Little Free Library as a gift to his mother, who was a devoted reader. When he saw the people of his community gathering around it, exchanging conversation as well as books, he knew he wanted to take his simple idea further. "I think Little Free Libraries open the door to conversations we want to have with each other," Bol said. .
Since then, his idea has become a movement, spreading from state to state and country to country. According to Little FreeLibrary.org, there are now 18,000 0f the little structures around the world, located in each of the 50 US states and 70 countries in Europe, Africa and Asia.
The Internet has helped to spread Little Free Libraries. But an Atlantic article says the little, structures serve as a cure for a world of e-reader downloads . The little wooden boxes are refreshingly physical and human. For many people, the sense of discovery is Little Free Librariesˈ main appeal. "A  girl walking home from school might pick up a graphic novel that gets her excited about reading; a man on his way to the bus stop might find a volume of poetry that changes his outlook on life," says the Atlantic article. "Every book is a potential source of inspiration "

In addition to lakes, Canada has a number of beaches as it has a long coastline on its north, east, and west. Travelers from around the world come in large numbers to enjoy sunbath at various beaches.

Niagara Fallslie on the border of Canada and the US. It is now popular for its beauty and is a valuable source of hydroelectric power. Niagara Falls are most attractive during summer season when weather condition is charming and attractive. At the Canadian side, floodlights illuminate(照亮) both sides of the fall for several hours after dark and the whole scene becomes magnificent.

When traveling to Canada, travelers can enjoy doing shopping at Toronto which is considered a leading city. It symbolizes American culture and the spirit of independence. Migrants form European, Latin American, Asian and Caribbean races inhabit the place and make it a plural society. Ottawa, on the other hand, is the capital of Canada and center of political activities.

Vancouveris an enlightening city in Canada which was named after British Captain George Vancouver, who explored the area in the 1790s. The city is a leading industrial place in Canada. Another tourist attraction in Canada is the capital city of British Columbia, Victoria. The city is located on the southern tip of Vancouver Island.

Travel in Canada is being made easy as transportation facilities are of higher standard. Besides, very few people know that Canada is a high-paying country in terms of wages per hour. In addition to a popular tourist destination, Canada is an economic powerhouse of North America, particularly in agriculture products. Canada dairy industry exports milk products around the world.

Nearly two decades after British writer J. K. Rowling introduced the famous boy wizard Harry Potter to the world in 1997, he is still making the news.

  The opening of the Wizarding World of Harry Potter theme park at Universal Studios in Hollywood in Los Angeles, USA, on April 7 brought the boy wizard's magical world to life.

  " It's as close as you ever could be to a film in a theme park," Alan Gilmore, an art director for the new Wizarding World of Hairy Potter, told Entertainment Weekly.

    From the start, visitors are greeted by a copy of the Hogwarts Express, the train that takes Harry Potter and his friends to Hogwarts School of Witchcraft and Wizardry every year.

    After arriving at the school's castle, visitors can jump on the exciting "Harry Potter and the Forbidden Journey" ride and take part in memorable scenes from Harry Potter. These scenes include flying above Hogwarts, taking part in a Quidditch match, escaping a dragon attack and avoiding a close meeting with the Whomping Willow(打人柳）.

    Walking through the park, visitors can enjoy cobblestone streets, narrow alleyways and buildings with chimneys made to look like those in a real English village. "It's all about making it feel like it's been here a thousand years Gilmore told Variety magazine. "And that includes moss(靑苔)and adding some dirt here and there."

    Die-hard fans can also enjoy foods and drinks like chocolate frogs, butter beer and every-flavor beans. And, of course，they can choose their first wands(魔杖). At 11 locations in the theme park, marked with a sign on the ground, visitors can wave their wands and make something magical happen!

  When people want to know about the weather, they usually go to their radios, TVs, newspapers, or to the Internet. However, you can also find many weather signs among wildlife, because of their highly developed senses. Drops in air pressure produce an effect on small animals in many ways. Mice and deer are good weather indicators. People who spend a lot of time outdoors have observed that, before a storm, field mice come out of their holes and run around, Deer leave high ground and come down from the mountains.

      Birds are especially good weather indicators because they also show the effect of a pressure drop in many ways. For example, some birds become irritable (急躁的) and quarrelsome and will fight over a piece of bread. Other birds chirp and sing just before a storm. It seems they know they won’t getanother chance for anhour or two. Birds also seek safe places before a storm. You will sometimes see birds settling in trees or gathering together on a wire close to a building. Pre-storm low pressure makes the air so thin that birds have difficulty flying.

It is unusual to see many birds flying overhead in the summertime, rather than during the periods in the spring or autumn. Watch for other weather signs if you see this. If they fly in the wrong direction, they may be flying ahead of a storm.

      By paying closer attention to some important signs in nature, we can become better prepared for any kind of weather.

The 2016 Oscars, the 88^th Academy Awards, once again thrilled people around the world, including the Chinese, who were excited about Leonardo DiCaprio winning the Best Actor Award.

But the annual carnival also put Chinese filmmakers in an awkward position, as no Chinese film makers ever pocketed a golden trophy(奖杯). The hard truth leaves people wondering when the nation, which is already the second largest film market, will earn a place in the well-known award ceremony’s spotlight.

There are good reasons to be optimistic about such an ambitious outlook.

First, China is one of the fastest growing film markets in the world, attracting abundant capital from home and abroad, which will attract more talented people to get into the industry. Latest statistics showed Chinese cinemas took a record of 6.87 billion yuan (about $ 1.05 billion) in ticket sales in February, with the monthly box office overtaking that of North America for the first time.

The achievement, which may be repeated in the future, has led to thinking that China’s annual box office could go on to surpass(超过) North America as soon as 2017. As capital rushes into the Chinese film industry, fierce competition is expected. The creativity and quality of homegrown movies, two outstanding shortcomings compared with Hollywood productions, will be improved.

Second, Chinese culture and stories have provided a rich source of inspiration for domestic(国内的) productions. For example, the most popular animations in China are the Kung Fu Panda series and Monkey King films. Once they master cutting-edge film technology and improve narration(叙述), Chinese film makers could see their potential released.

Also showing promise is the younger generation of filmmakers, who are born after 1970. With more professional and international training compared with their predecessors(前辈), such as Zhang Yimou, they are equipped to make breakthroughs.

Young directors, who often travel to the United States and Europe for seminars and award ceremonies, are also more familiar with Hollywood productions. This being said, no one can predict the exact year when a homegrown film will surprise the world greatly.

Patience is gold for domestic filmmakers.

   Dr. Paul Kelley, a sleep expert, and his colleagues, including well-known Oxford sleep researcher, Professor Russell Foster, presented an interesting theory at the British Science Festival in Bradford. They said that school days should start at 10:00 and university at 11:00 to better match the biological rhythms of adolescents and young adults.

   Dr. Kelley said most people wake up to alarms because they have to go to work. In fact the body clock of most people between the ages of 10 and 55 is not well suited to rising early. This means insisting on an early start can lead to a lack of sleep, which in turn can affect learning and health. Adolescents in particular are the most affected, which is "a huge society concern".

   Dr. Kelley and his colleagues are leading a project called Teensleep, which is currently looking for 100 schools from around the UK to test the .idea. The Teensleep experiment, which is funded by the Wellcome Trust and the Education Endowment Fund, will randomly divide its 100 schools into four groups. One group of schools will shift (转换) their school days for 14-to 16-year-olds to a 10:00 start. Another group will offer "sleep education" to their students. This involves helping students and staff "realize wise ways of making their sleep good sleep", such as avoiding screen-based activity in the evening. The third group of schools will introduce both a later start and sleep education, while the fourth will make no such changes. The experiment will start in the 2016-17 academic year, and the researchers plan to report their results in 2018.

   Dr. Dijk, a professor of sleep and physiology at the University of Surrey, cautioned that shifting the school day might be of limited use without changing other habits that affect our sleep, especially night-time light exposure. But he will observe the experiment with interest.

By now, we are all aware that social media has had a tremendous influence on our culture, in business, on the world-at-large. Social media websites revolutionized the way people communicate and socialize on the Web. However, aside from seeing your friends’ new baby on Facebook, or reading about Justin Bieber’s latest conflict with the law on Twitter, what are some of the real influences?

Social networks offer the opportunity for people to re-connect with their old friends and acquaintances, make new friends, share ideas and pictures, and many other activities. Users can keep pace with the latest global and local developments, and participate in campaigns and activities of their choice. Professionals use social media sites like LinkedIn to enhance their career and business development. Students can work together with their peers to improve their academic and communication skills.

Unfortunately, there are a few downsides too to social networking. If you are not careful, immoral people can target you for cyber bullying and disturbance on social sites. School children, young girls, and women can fall victim to online attacks which can create tension and suffering. If you are a victim of cyber bullying, do not take it lying down, but try to take appropriate legal action against the attacker.

Many companies have blocked social networks as addicted employees can distract themselves on such sites, instead of focusing on work. In fact, studies show that British companies have lost billions of dollars per year in productivity because of social media addiction among employees.

Also, what you carelessly post on the Net can come back to trouble you. Revealing personal information on social sites can make users vulnerable(易受伤害的)to crimes like identity theft, stalking, etc. Many companies perform a background check on the Web before hiring an employee. If a potential employee has posted something embarrassing on social media, it can greatly affect their chances of getting the job. The same holds true for our relationships too, as our loved ones and friends may get to know if we post something undesirable on social networks.

Social media has its advantages and drawbacks as each coin has two sides. It is up to each user to use social sites wisely to enhance their professional and social life, and exercise caution to ensure they do not fall victim to online dangers.
