Anxiety has now surpassed depression as the most common mental health disease among college students, though depression, too, is on the rise. More than half of students visiting campus clinics cite anxiety as a health concern, according to a recent study of more than 100,000 students nationwide by the Center for Collegiate Mental Health at Penn State. Nearly one in six college students has been diagnosed with or treated for anxiety within the last 12 months, according to the annual national survey by the American College Health Association.

    The causes range widely, experts say, from mounting academic pressure at earlier ages to overprotective parents to engagement with social media. Anxiety has always played a role in the development of a student's life, but now more students experience anxiety so acute that they are seeking professional help. Like many college clinics, the Center for Counseling and Psychological Services at the University of Central Florida (UCF)— one of the country's largest and fastest-growing universities, has seen sharp increases in the number of clients: 15.2 percent over last year alone.

    Anxiety has become characteristic of the current generation of college students, said Dan Jones, the director of Counseling and Psychological Services at Appalachian State University in Boone, N. C. Because of increasingly pressures during high school, he and other experts say, students arrive at college preloaded with stress. Accustomed to extreme parental oversight, many seem unable to govern themselves. And with parents so accessible, students have had less incentive to develop life skills. “They can't tolerate discomfort or having to struggle,” Dr Jones said.

    More often, anxiety is mild and temporary, the indication of a student under the control of a normal developmental issue-learning time management, for example, or how to handle rejection from a sorority. Mild anxiety is often treatable with early, modest interventions. But to care for rising numbers of severely troubled students, many counseling centers have moved to triage protocols (分诊措施). That means that students with less urgent needs may wait several weeks for first appointments.

    Like many college counseling centers, UCF has designed a variety of daily workshops and therapy groups that implicitly and explicitly address anxiety, depression and their triggers. Next fall the center will test a new app for treating anxiety with a seven-module cognitive behavioral program, accessible through a student's phone and augmented with brief videoconferences with a therapist. It also offers semester-long, 90-minute weekly therapy groups, such as “Keeping Calm and in Control”, “Mindfulness for Depression” and “Building Social Confidence” -for students struggling with social anxiety.

    There are 115 distinct (独特的) species of pine trees with 35 native to North America. Pines are defined as evergreens with long, needle-like leaves and are only native to the northern hemisphere. Pine trees are an adaptable and tough species that can survive in many conditions where other plants cannot. The average pine tree is 45 to 60 feet tall, but some are nearly twice as high.

Western White Pine

    The western white pine grows the tallest of any pine tree, reaching up to 110 feet in height. They have blue-green needles arranged in bundles (束) of five and produce a long cone (球果).

Bristlecone Pine

    The bristlecone pine grows slowly, reaching about 20 feet tall. It is one of the oldest species of pine.

Mexican Pine

    The Mexican pine can grow to 50 feet tall, with long, slender needles that drape (下垂) off it like a weeping willow (柳树). Often nicknamed the “willow pine”, it is native to Mexico. Its leaves can droop up to 12 inches long.

Sugar Pine

    The sugar pine is another of the large pine species, such as the bull pine, but it also has the largest cones of any pine species, at 10 to 20 inches long. It grows from Oregon to California and is often used for construction.

Jack Pine

    The jack pine is one of the smallest species of pine with rare leaves. Compared with the pines mentioned above, it doesn't seem to belong in the family. It is considered a member of the scrub-pine family; it prefers sandy soil.

    Retirement (退休) should be time of joy and freedom. However, for some people retirement comes with feelings of depression (沮丧), which makes life difficult for them.

    Retirement is a major life change. Even good changes usually involve some kinds of loss. When you retire, you find yourself lacking whatever working used to provide. That could include, for example, 1. knowing you're working for society, 2. getting admiration from your skills, 3. having “aha” moments when you solve problems, 4. having people to socialize with, and 5. simply having a place to go and a reason to get out of bed every day. For most people, there's a financial loss, too. Also, retirement age is a time when a lot of people have to deal with losing their parents or having serious health problems of their own.

    Because of all these, retirees are more likely to get depressed.

    Depression is very harmful. First, depression can make physical health problems worse. Second, it takes a toll on relationships, because it can make people angry. Third, it's hard to get  much done when you're depressed.

    What can we do to overcome (克服) the feelings of depression? First, do all the things that help depression in general: drink enough water, exercise, talk to friends, have a hobby, laugh, and spend time in nature. If you feel depressed more often than not, it's probably time to talk to a doctor about your feelings. Second, it's important to keep busy and get out of the house when you can. Make specific plans with friends. Take a class Volunteer. Or just make sure you start each day with some kind of goal. Third, try to focus on what you've gained by retiring. Think about what you may have now that you wished you had before you were able to retire. For example, days that are less stressful, a chance to rest and take better care of your body, more time for your family and yourself. To write, to start a hobby and to learn something new are all new possibilities. Finally, tell your story. You've lived a long time and you become an oral historian each time you talk with someone about your experiences. You can also write in a journal or make a video recording of your memories. Telling your stories can help you look back on your life and career with a sense of wholeness and achievements.

    There are countless short videos on YouTube. It's a website for people to post video made by themselves. Many people make a lot of money through doing so. Then, who made the most over the past year?

    YouTube's top-earning celebrity is a 25-year-old video-game-playing young man who shows a strong sense of humor in his videos. He earned $12 million over the past year. Forbes magazine says Sweden's Felix Kjellberg, better known by his handle "PewDiePie", tops its first list of people who have turned short videos into huge piles of cash.

    YouTube stars make money mainly by getting paid to interact with products on their channels and sharing ad revenue(收入) with YouTube. Some also star in movies, write books, go on tour, or sell music. They're a hit with younger audiences and brands trying to reach the next generation of consumers.

    Two acts tied for the second place on Forbes' list, both earning $8.5 million: comedy prankster(搞恶作剧的人) duo Smosh(Ian Hecox and Anthony Padilla) and the Fine Brothers(Benny and Rafi Fine). Dancing violinist Lindsey Stirling ranked fourth with $6 million. Tied for fifth were comedians Rhett and Link(made of Rhett McLaughlin and Charles Lincoln III) and video game commentators(解说员) Olajide Olatunji, known as "KSI," with $4.5 million. Make-up artist Michelle Phan was seventh at $3 million. The No. 8 place was a three-way tie at $2.5 million shared by comedian Lilly Singh, or "Superwoman;" prankster Roman Atwood; and chef Rosanna Pansino.

    Forbes is best known for its list of billionaires and this list marks its first attempt at ranking YouTube stars. It says it measured earnings before management fees and taxes and came up with the figures based on data from online sources such as Nielsen, IMDb and interviews with managers, lawyers, industry insiders and the stars themselves.

    It's pleased to receive gifts from your loved ones. I have received many Christmas gifts over the years. But the best gift I ever received was presented to me by a stranger. I never even knew his name and I only had contact with him for less than 60 seconds. His Christmas present to me changed the way I had thought about people and Christmas.

    It was several years ago when my wife asked me to meet her at the local department store on Black Friday morning. They had advertised a child's bike that she wanted to purchase for our son. We stood with a very large crowd, waiting for the manager to blow the whistle. After a while, the whistle blew. It was like throwing a bucket of fish into a tank of sharks. I told my wife that if we obtained a bike, fine, but if we did not, I was OK with that too.

    As the shelf of bikes began to gradually decrease in size, I saw my polite opportunity to wrap my hands around the corner of one of the boxes. I lifted it off the box and suddenly felt some mild resistance. I looked up to see one of the largest gentlemen I had ever seen in my life. Threat was not the word to describe his presence. He was decorated with numerous belts of metal pointed leather around both arms and even his neck. Tattoos (文身) were an obvious passion of his.

    I started to return anxiously the box but he gently pushed it back in my direction and back into my hands. He then directed it into my shopping cart. He looked at me, smiled, and said, “Merry Christmas.” My wife and I went to the checkout, paid for the bike and went home. All the way home I was thinking that this moment was by far the best Christmas gift I had ever received. The kindness of a stranger that broke all previous views I may have had of stereotypes and prejudices. I will never forget the tenderness of a human heart in a simple act.

    Once upon a time, there was a little boy who wanted to meet the king. He set off, walking towards the king's castle. After many years of walking, the king's castle came into his view. However, as the boy drew closer to the outside of the castle, the guards took notice of him.

    "Get out of here!" commanded the guards.

    Well, the little boy didn't have to be told twice. He turned...and ran right away. All he wanted to do was to tell the king wonderful things, and see all the beautiful things in the king's house. But he couldn't even get near the castle! The boy finally stopped running, sat down and cried.

    A young man happened to be coming down the path at the very moment. He saw the little boy and came up. "What's wrong, young man?" he asked.

    "Sir, I walked and walked just to see the king. But these guards made me frightened. I wanted to tell the king how lovely everything is and just tell the king that I just wanted to see him!"

    The man looked at the little boy thoughtfully. "Look, why don't you try again. Don't lose heart. I'll come with you this time."

    The little boy got up and took the man's hand. The king's guards spotted them.

    "Look, mister, we don't have to do this...I don't want you to get hurt. We can just turn around now."

    The man held the little boy's hand and went on. The boy really thought the man might be crazy until he looked back up at the guards. They were all smiling now. The little boy was surprised.

    "Who are you?" asked the little boy in surprise.

    "Why, I'm the king's son. You can enter the castle and be with the king," said the man.

    The little boy broke into a huge smile.
