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.

    Worldwide, the most people willing to return your mobile phone if you've lost it are to be found in Slovenia, and the fewest in Malaysia. This finding is the result of an interesting study in 32 of the world's largest cities. Altogether, researchers 'lost' 960 new mobile phones. They got back 654 of them，or 68 percent. Prague came in at number eight. There, 23 out of 30 people who were willing to return the mobile phone.

    It wasn't a traditional study. Two researchers carefully chose different places such as areas with high crime(犯罪)and busy downtown shopping areas, to “lose” the phones. When one of the researchers dropped a phone, the other would keep watching from a distance. The honest finders tried their best to find the owner with the help of the address book in the phone. They were told why the study was done and asked why they acted the way they did.

    It was found that the busier the place where the researchers dropped the phone, the greater the chance of it being returned. Another interesting finding was that women were generally more likely than men to return the phone. Researchers also found that most people still have a sense of honesty. “Crime is simply not good behavior (行为), ”said an expert. “People want to trust others, and want to be trusted.”

    Every year gray whales swim a 10,000 miles round-trip, from the cold waters near Alaska, down the coast of North America to the warm waters near Mexico, and back again. It is one of the longest migrations (迁徙) of any mammal (哺乳动物).

    All day, all summer long, in the cold waters near Alaska, gray whales eat and eat.

    Instead of teeth, gray whales have baleen (鲸须) they use to get food from ocean water. They get big mouthfuls of muck (淤泥) from the ocean floor, then push that muck right back out through their baleen. The mucky water flows through, but tiny animals get trapped in the baleen and licked up.

    When the water starts to freeze, the whales begin their long trip south. They swim night and day, without stopping to eat or rest. During the long journey, migrating whales may push their heads out of the water to see where they are.

    Two months later, the whales reach Mexico. Babies are born here in warm, shallow (浅的) waters called lagoons (濒海湖). Ocean lagoons have no food for the adults, but the babies are safer here than in the open seas. All winter the babies grow big and strong.

    In spring first the dads and teenagers leave the lagoons, then the moms with babies. Migrating gray whales swim close to shore, especially moms with babies. The ice is melting up (融化) north, and it's time for the hungry whales to make the long journey back to their summer feeding grounds.

    Author Avi, winner of a Newbery Award, a Scott O'Dell Historical Fiction Award, and several Boston Globe-Horn Book Awards, may have seen his first children's book published in 1970, but that doesn't mean he's lost his talent for connecting with young fans.

    The American writer, born in 1937, agrees that getting involved with his readers is one of the key reasons he keeps writing, and that he's been fortunate enough to hear directly from readers about the impact (影响) his books have had. “I have been touched many times by readers who find some special connection between their lives and something I have written: the Danish girl who read something of mine in Danish, and struggled to communicate that in her poor English; the autistic (自闭症的) boy who somehow found something meaningful about my books that reached his own inner life; the women who have told me how important The True Confessions of Charlotte Doyle was to them when growing up."

    Beyond his fans' questions about the characters he's created, the writer's most commonly heard question may be about his own use of the single name “Avi." “As a young adult, I was a reader of French literature, which has that one name tradition: Moliere, Racine, Anouilh, Gide, and so on," he explains. “Avi was given to me by my twin sister when we were very young children, and it stuck. Then my family discouraged me from taking up writing as a career because they considered my writing poor. By using Avi, I was showing my determination to them."

    Although he believes－and has the awards to show－that his writing skills have improved, writing still doesn't come easily to him, despite having over sixty books to his credit. “I never studied writing in any formal sense. I taught myself to write by reading, and by imitating what I was reading," he says.

    The writing task may be tough, but the payoff is big. “To create, share, and support the gift of reading and literature, is to give young people the gift of many worlds, within and without," Avi states.

    Elephants have impressed us for centuries. They are big, clever, and sociable. But what if someone told you that they may also hold the key to fighting cancer (癌症)?

    People have been wondering why elephants do not develop cancer, even though they have lifespans (寿命) that are similar to humans, living for around 50 to 70 years.

    Now scientists believe they know why. A team at the University of Chicago, US has found that elephants carry a large number of genes that stop tumors (肿瘤) from developing. To be precise, they found 20 copies of an anti­tumor gene called TP53 in elephants. Most other species, including humans, only carry one copy.

    According to the research, which was recently published on the online science network BioRxiv, the extra copies of the gene improved the animal's sensitivity to DNA damage. This lets the cells quickly kill themselves when damaged before they can go on to form deadly tumors.

    “An increased risk of developing cancer has stood in the way of the evolution of large body sizes in many animals，” study author Dr. Vincent Lynch told The Guardian. If every living cell (细胞) has the same chance of becoming cancerous, large creatures with long lifespans like whales and elephants should have a greater risk of developing cancer than humans and mice do. But across species, the risk of cancer does not show a connection with body mass.

    This_phenomenon was found by Oxford University scientist Richard Peto in the 1970s and later named "Peto's paradox". Evolutionary (进化的) biologists believe it results from larger animals using protection that many smaller animals do not. In the elephant's case, the making of TP53 is nature's way of keeping this species alive.

    The study also found that when the same genes were brought to life in mice, they had the same cancer resistance (抵抗) as elephants. This means researchers could use the discovery to develop new treatments that can help stop cancers from spreading or even developing in the first place.

    "Nature has already figured out how to prevent cancer, " said Joshua Schiffman, an oncologist at the School of Medicine, University of Utah, US.

    “It's up to us to learn how different animals tackle (处理) the problem so we can use those strategies to prevent cancer in people.”

    In the US and Britain, the slogan around colleges was "Save water. Shower with a friend." Now, Wuhan University has come up with another system for the campus bathhouse. It charges students for the amount of time in a shower. Before entering the bathhouse, students pay for the amount of time they want in the shower with cash or their student ID card. The clock starts ticking the minute the tape is turned on. It pauses when a button is pressed for soap. An integrated circuit (IC) card reader at each tap shows the time. No money, no water. The benefits of the new system can be seen with the old system, which charged 1 yuan for each person regardless of time in the shower. The university used about 320 tones of water daily under the old system, but only 160 tons now.

    Many students use the new system but opinions on it are divided. Some students say it is bad because bathing had become a sort of race. Many people using it for the first time are not sure how long they need to shower. Some might be embarrassed if their time is up and they're still covered in soap. They have to ask the bathhouse worker to help them buy extra time.

    "It's a flaw in the system that you can not buy extra time on the ID card," said Ren, a freshman in Wuhan University. The university is also considering some students' suggestions that they be allowed to pay after they've finished the shower. Not surprisingly, some are complaining about losing the hour shower. But many students say the move helps them develop a water-saving sense.

    Without the time limits, most students tended to shower for 30 to an hour in the bathhouse.

    Some even used the hot water to wash their clothes. "In my experience, 10-20 minutes is enough," said Dai Zhihua, a third-year student who usually takes 8 minutes.

    A similar system has been installed in other universities. Shanghai Normal University introduced it at its Fengxiang Campus in September. The bathing fee there is 0.2 yuan per minute. One male student responded by setting a record with a two-minute shower.
