A recent study by Citi Retail Services found that a growing number of people are embracing digital wallets or e-wallets, due in large part to their convenience and ease of use.

    E-wallets have been called the future of real-world payment technology.With major players like Alipay,WeChat and Apple Pay becoming popular,it seems to be a safe bet that a change in consumer payment technology is coming soon.

    CNN reporter Paul Ripley experienced a day in Beijing without his wallet."In China's largest cities, you can definitely survive without carrying a pocket full of cash and credit cards-as long as you've got your smartphone."He paid for breakfast by scanning a QR code on the window of a hole-in-the-wall restaurant.All he had to do was to enter a password and the transaction was complete.

    Unlike the situations in the US and other countries,"China doesn't have a really money-making credit card system, so Chinese people just skipped credit cards and went straight to mobile payments."Gu Yu,co-founder of the new payment app Mileslife,told CNN.He also pointed out the advantages of mobile payments."No coins or bills that can be lost or stolen. electronic receipts, the ease of keeping rack of spending-and of course,no wallet taking up space."he said.

    However, if we want to make e-wallets a mainstream trend a lot of things will have to change over the coming years.Perhaps one of the most important things that need to be changed is how people regard e-wallets.Linda Barrabee,research director for NPD Connected Intelligence, said in a statement."In order to promote on-the-go consumer transactions and commerce, wireless carriers, credit card companies, and e-commerce companies need to make sure the process is convenient,simple,and secure for consumers."

    Astronomy (天文学) is the oldest science known to man. Thousands of years ago man looked at the stars and wondered about heavens(天堂). But the six planets that he could see with his eyes alone limited man.

    The Greeks studied astronomy over 2,000 years ago. They could see the size, color, and brightness of a star. They could see its place in the sky. They watched the stars move as the seasons changed. But the Greeks had no tools to help themselves study the heavens.

    Each new tool added to the field of astronomy helped man reach out into space. Until there were telescopes(望远镜), man did not know much about the moon. He did not know that the planet called Saturn(土星) had rings around it. His sight was so limited that he could not see all the planets. In the early 1700s, people thought there were only six planets. Pluto (冥王星), the last of the nine planets to be discovered was seen until 1930.

    Before the spectroscopes (分光镜), man didn't know what kind of gas was in the sun or other stars, without radio telescopes(射电望远镜), we did not know that radio noise came from far in space.

    Today, astronomy is a growing science. We have learned more in the past fifty years than in the whole history of astronomy.

    Most of us would be traveling for the rest of our lives if traveling abroad were not so expensive. But there is no need for you to cut down on the number of holidays you're having this year. Below are some of the cheapest places to travel to this year.

    Sri Lanka

    Great seafood, beautiful beaches, and amazing jungles await you in Sri Lanka. It is definitely one of the cheaper places to travel to as well. It will be possible for you to live in high-class hotels and resorts for as little as 70 dollars a night! If you don't want to spend that much money, you can find hostels, and smaller hotels for as little as 20 dollars a day. You can just spend the day exploring Anuradhapura or go adventuring in Habarana Lake as well!

    Hungary

    It might be surprising to see Hungary on the list of cheap places to travel to this year. It is located in the most expensive continent on the earth, after all. However, Hungary is the country where you get rooms for as little as 16 Euros, and beer for about 4 Euros each! This is definitely a bargain! You can get a travel card to use the public transport throughout the country, and save quite a few dollars on that as well. Spend a few nights in Budapest or head out to the northern hills where you can hike and swim in the clear lakes!

    Greece

    There was a time when Greece was unbelievably expensive, but due to its recent economic problems, Greece has become quite cheap to travel to. Price of accommodation and food is at an all-time low, so this might definitely be a great time for you to visit! There are some areas of the country that will be expensive like Santorini or Mykonos, but if you just want to explore local Greek culture, you can walk on the streets of Greece, or adventure across the smaller islands around like Kefalonia or Piraeus or Los!

    Tess was eight years old. Her little brother Andrew was very sick and their parents were completely out of money. She heard Daddy say to her tearful Mother, "Only a miracle can save him now."

    Tess took her money and made her way six blocks to Rexall's Drug Store.

    "And what do you want?" the chemist asked in an annoyed tone of voice. "I'm talking to my brother from Chicago whom I haven't seen for ages."

    "Well, I want to talk to you about my brother," Tess answered back in the same annoyed tone. "He's really sick. He has something bad growing inside his head and my Daddy says only a miracle can save him now. So how much does a miracle cost?"

    "We don't sell miracles here, little girl. I'm sorry but I can't help you," the chemist said, softening a little.

    "Listen, I can help you." The chemist's brother was a well-dressed man. He asked Tess, "What kind of miracle does your brother need?"

    "I don't know," Tess replied. "Mommy says he needs an operation. But my Daddy can't pay for it, so I want to use my money."

    "How much do you have?" asked the man from Chicago. "One dollar and eleven cents," Tess answered. "And it's all the money I have, but I can get some more, if I need to."

    "Well, what a coincidence (巧合)," smiled the man. "A dollar and eleven cents － the exact price of a miracle for your little brother. Take me to where you live. Let's see if 1 have the kind of miracle you need."

    That man was Dr. Carlton Armstrong, a surgeon in neurosurgery (神经外科). The operation was completed without charge and it wasn't long until Andrew was home again and doing well．

    Tess smiled. She knew exactly how much a miracle cost… one dollar and eleven cents… plus the faith of a little child.

    Pizza is a pretty universal treat, but where did it start? Here are three things you probably didn't know about pizza.

    1: Pizza's Origins Are Half-Baked.

    The Neapolitans（那不勒斯人）in Italy are proud of saying they invented pizza, but it's probably more accurate to say, they perfected it. The idea of putting toppings on a flatbread and baking it started in the 6th century B. C. But the people of Naples were the first to put tomato on a flatbread in the 16th century. From its start, pizza was a food of the poor, as it was cheap, filling and easy to eat on the run. In Italian, the word “pizza” refers to anything that is made and then pressed flat.

    2: Pizza Margherita Is Not Exactly a Symbol of Italy.

It was said some day in 1889, a local baker named Raffaele Esposito created three pizzas for Queen Margherita when she was on a tour of Italy. The queen loved the version that had tomato, basil and mozzarella cheese— and just happened to match the colors of the Italian flag. So Esposito named the pizza after her.

    But Pizza historian Scott Wiener points out that Italy was unified in name only in 1889 so it was unlikely any Neapolitan baker would want to celebrate “the Northern conquerors.” Further, the letter of gratitude for the pizza from the royal household that Pizzeria Brandi displays appears to be a fake（赝品）and may just have been a marketing plan.

    3: Hawaliian Pizza Invented by a Canadian.

    Sam Panopoulos, from Greece originally moved to Canada at the age of 20. In 1962, he decided to put some ham and pineapple on a pizza at one of his restaurants in Ontario.

    “We just put it on for fun to see how it was going to taste,” he told the BBC in 2017. Panopoulos named it the Hawaiian pizza after the brand of canned pineapple he used. The mix of sweet and savory toppings caught on with a certain part of the pizza-loving public. The inventor died in 2017.

Urban Transportation in Canada

Public transportation & Transit passes

All cities and most major towns in Canada have a public transportation system with one or more modes of transportation（bus, subway, train, etc.）. The bus is the most common form of urban transportation in Canada. To use public transportation, you must purchase a ticket or a transit pass. Transit passes allow you unlimited use of public transportation for a specific period（one month or more）. They are usually cheaper than buying many tickets if you plan to use public transportation often.

Transportation for people with disabilities

Public transportation often has features to assist people with disabilities. In many cities and towns, there are also transportation services available specifically for people with limited mobility, such as specially equipped buses. You can find out about these services in the same way you would learn more about other public transportation options.

Etiquette（礼节）on public transportation

When taking public transportation such as a bus or train, it is important to understand the unspoken rules of conduct in the shared space. Here are a few things to note:

Be polite and respectful to others around you. For example, maintain an appropriate noise level when talking or making a phone call.

If you are carrying a back pack or a large shoulder bag in a crowded public transit vehicle, keep it close to you, preferably at your feet to avoid hitting people with it as you walk by.

Avoid pushing or touching others in order to make more room for yourself. Sometimes public transit can become very crowded, but it is important to keep calm and give others appropriate personal space.

Have your proof（证明）of payment accessible in case you are asked to show it.
