How to save money to visit Shanghai Disneyland?

    The “happiest place on earth” is a top destination on many families' bucket lists. But taking a vacation to Disney World can be difficult to do on a budget. There are some considerations that you can make to reduce the cost of your Disney World vacation.

1). Buy Souvenirs in Advance

    Disney has influenced practically every industry, which makes it easy to find Disney items anywhere, from Walmart, Target, and your local grocery store to department stores and Amazon. You can save a lot of money by purchasing items before your trip at these less-expensive places than at Disneyland.

2). Make an Autograph Book

    An autograph (亲笔签名)book is seen as a must-have by many Disneyland enthusiasts and is a memory you can take home with you. These books can cost anywhere from $7.95 to $19.95 at the Disney Store and up to $30 for the latest-and-greatest autograph book at Disneyland, such as the park's 60th anniversary edition. Other choices can get the job done for under $5. For example, you can buy a small photo album; cute pads or notebooks.

3). Eat Breakfast Before You Arrive

    Breakfast is almost as pricey as lunch or dinner if you eat inside the Disneyland parks. If you have a hotel with a free breakfast, take advantage of it. If you want to eat out, eat at a local restaurant that is inexpensive or has a kids' menu, such as McDonald's which is close to the park.

    4). Take Advantage of Discounts Offered to Special Groups

    Disney offers a wide variety of discounts, including for military service members, college students, teachers, and youth groups. If you think you might qualify for a special discount or group rate, call the Disneyland Resort to book tickets.

    Old age may not sound exciting.But recent findings offer good news for older people and for people worried about getting older.Researchers found that people become happier and experience less worry after they reach the age of fifty.In fact，they say by the age of eighty­five，people are happier with their life than they were when they were eighteen years old.

    The findings came from a survey of more than three hundred forty thousand adults in the United States.The Gallup Organization questioned them by telephone in 2008.At that time，the people were between the ages of eighteen and eighty­five.The researchers asked questions about emotions like happiness，sadness and worry.They also asked about mental or emotional stress.

    Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study.His team found that levels of stress were highest among adults between the ages of twenty­two and twenty­five.The findings showed that stress levels dropped sharply after people reached their fifties.

    The study also showed that men and women have similar feeling patterns as they grow older.However，women at all ages reported more sadness，stress and worry than men.

    Researchers say they do not know why happiness increases as people get older.One theory is that，as people grow older，they grow more thankful for what they have and have better control of their feelings.They also spend less time thinking about bad experiences.

    Professor Stone says the emotional patterns could be linked to changes in how people see the world，or maybe even changes in brain chemistry.

    The researchers also considered possible influences like having young children，being unemployed or being single.But they found that influences like these did not affect the levels of happiness and well­being related to age.

    A so-called “smart drug” intended to improve people's cognitive (认知的) function to protect the brain from altitude sickness.

    Visiting high-altitude sites for work, spot, religious pilgrimages and military can result in cognitive effects, including memory loss and attention difficulties. There's little you can do to prevent these symptoms except acclimatize -but this takes time and doesn't always work. A drug called oxiracetam might be the answer.

    ShengLi Hu at the Third Military Medical University, Chongqing, China and her colleagues studied the performance of male military personnel at altitude. All lived in towns around 1,800 meters above sea level, During the study, they spent eight days at this altitude and then climbed for three days to reach 4,000 meters, where they stayed for up to a month.

    Twenty participants took oxriacetam three times a day for the first 15 days of the study, while another 20 received no intervention. The man did tests of attention and memory at the start and end of the study and 20 days in, by which time they had been at 4,000 meters for nine days.

    While all the participants experienced a drop in cognitive ability at 4,00 meters, those who took oxiracetam showed a much smaller drop than the control group.

    The team found that at high altitude the brain stem, which plays a critical role in supporting basic living functions, received blood at the expense of areas responsible for more advanced cognitive functions. But in people who took oxiracetam, blood flowing throughout the brain rose, thus offering more oxygen to these areas. This may be how the drug seems to lessen cognitive problems like with low oxygen.

    It isn't yet known whether diverting blood in this way could have negative effects in the long run. "The results are striking and imply that oxiracetam may be beneficial for helping to relieve cognitive ability decline caused by altitude." says Timothy Hales at the University of Dundee, UK.

    Wolves are important animals in the traditions and stories of most Native American tribes. To Native Americans, wolves often represent bravery. The animals also are signs of strength, loyalty, and success at hunting. Other cultures--such as the ancient Celtic and Nordic peoples-also placed high value on wolves.

    However, from the wolves in horror films to the wolves in children's stories, wolves get a bum rap(不公正的惩罚) in both literature and English expressions.

    To begin with, there is the term lone wolf. The lone wolf isn't a bad person. But they like to do things on their own. However, the term can mean something less than desirable. Lone wolf makes you think the person doesn't want to be around people because he or she dislikes them.

    Now, let's move on to the home.

    Parents might criticize their children for wolfing down their food. In other words, the child eats very quickly and without care. And if someone says a child was raised by wolves, that child has bad manners and is behaving like a wild animal. A wolf at the door means someone to whom you owe money is waiting just outside your door.

By the way, there are two popular wolf-related expressions that come from Aesop, the ancient Greek storyteller.

    The first is a wolf in sheep's clothing. A wolf in sheep's clothing describes someone who acts and looks nice on the outside but is bad on the inside.

    Aesop's other wolf fable also involves a shepherd, but not a hardworking one. He is known as the boy who cried wolf. People who cry wolf are not trusted. People are so familiar with this story, you simply have to say cry wolf for them to know what you mean.

    Google previously announced successful tests of machine learning systems designed to assist doctors. In one case, Google reported AI had examined eye diseases with equal accuracy to doctors. Other tests showed that machine learning can be used to study large amounts of patient data to predict future medical events.

    Now the company has published two new studies showing a high level of success in identifying metastatic breast cancer. Metastatic means that cancer has spread from its main area to other parts of the body. Metastatic breast cancer is one of the deadliest, causing about 90 percent of all breast cancer deaths worldwide.

    In metastatic breast cancer patients, the cancer often travels to nearby lymph nodes（淋巴结）. Usually doctors examine lymph node tissue under a microscope to see whether cncer is present Google notes that previous studies have shown that up to one-fourth of metastatic lymph node classifications end up being changed after a second examination. In addition, studies show that small metastatic material can be missed up to 67 percent of the time when examinations happen under extreme time restrictions.

    Google says it created a mathematical algorithm(算法).The algorithm, called Lymph Node Assistant, is trained to find characteristics of tissue affected by metastatic cancer. When the system examined tissue images (图像), it was able to differentiate between metastatic cancer and non-cancer 99 percent of the time. In addition, the Lymph Node

    Assistant is highly effective at finding the positions of the cancers. Some of these positions would be too small for doctors themselves to identify. The research also showed that the algorithm method can reduce the usual time needed to examine the disease by about 50 percent.

    But Google makes clear the Al-based system is not meant to replace the work of medical professionals. Instead, it is designed to reduce the number of false identifications and help doctors work faster and more effectively.
