Driving in Canada is similar to driving in many parts of the United States. Distances and speeds, however, are posted in kilometers per hour and some signs, particularly in Quebec, may only be in French.

    Unless otherwise posted, the maximum (最大限度的) speed limit in Canada is 50km/hr in cities and 80km/hr on highways. On rural highways, the posted speed limit may be 100km/hr. It is illegal to take automobile radar detectors (汽车雷达检测器) into Quebec, Ontario, Manitoba, and the Yukon. Seat belt use is required by law for all passengers, and child car seats must be used by children under 40 pounds. Some provinces require drivers to keep their vehicles' headlights on during the day and some have banned (禁止) driving while using a hand-held cell phone. Motorcycles cannot share a lane (车道), and safety helmets for motorcycle riders and passengers are necessary. Running a red light is a serious crime throughout Canada and drivers are advised to stop before starting when a light turns green.

    Winter travel can be dangerous due to heavy snowfalls and icy conditions. Some roads and bridges are often closed in winter. Snow tires are required in some provinces. Travelers should also be careful about animals while driving at night in rural areas.

    Highway 401, from Detroit to Montreal, is one of the busiest highways in North America. It has been the scene of many deadly traffic accidents due to sudden and severe weather changes, high rates of speed, and heavy truck traffic. Thus drivers should be alert while travelling here.

    A spaceship is flying to the sun in summer 2018! It will be the first-ever to a star and will be one of the biggest achievements space exploration (探险) in human history. The purpose is to study the sun's outer atmosphere and better understand how stars work.

The spaceship, with no man inside, will fly within 4 million miles of the sun's surface - right into the solar atmosphere, where the temperature is over 4,500℃. To protect the spaceship, it is covered with a 12cm-thick coating.

    The spaceship is called Parker Solar Probe and it is named after Eugene Parker, a professor from the University of Chicago. It's the first NASA spaceship to be named after a researcher who is still alive. In 1958, Eugene Parker first created the term “solar wind”-the sun sending out a flow of particles (颗粒) and energy.

    “The spaceship is going where it has never been before. It's very exciting that we'll finally get to know more about the solar wind. I'm sure there will be some surprises. There always are,” said Professor Parker.

    Parker calls it a heroic scientific space adventure, and he means that the spaceship will have to experience high temperatures and sun radiation (辐射). “The spaceship is going to do the hottest and fastest work. I love to call it the coolest hottest work under the sun,” said Scientist Fox Nasa.

    Before the 1830s most newspapers were sold through annual subscriptions in America, usually $8 to S10 a year. Today $8 or $10 seems a small amount of money, but at that time these amounts were forbidding to most citizens. Accordingly, newspapers were read almost only by rich people in politics or the trades. In addition, most newspapers had little in them that would appeal to a mass audience. They were dull and visually forbidding. But the revolution that was taking place in the 1830s would change all that.

    The trend, then, was toward the "penny paper" ­ a term referring to papers made widely available to the public. It meant any inexpensive newspaper; perhaps more importantly it meant newspapers that could be bought in single copies on the street.

      This development did not take place overnight. It had been possible (but not easy) to buy single copies of newspapers before 1830, but this usually meant the reader had to go down to the printer's office to purchase a copy. Street sales were almost unknown. However, within a few years, street sales of newspapers would be commonplace in eastern cities, At first the price of single copies was seldom a penny ­ usually two or three cents was charged ­ and some of the older well-known papers charged five or six cents. But the phrase "penny paper" caught the public's fancy, and soon there would be papers that did indeed sell for only a penny.

    This new trend of newspapers for "the man on the street" did not begin well. Some of the early ventures were immediate failures. Publishers already in business, people who were owners of successful papers, had little desire to change the tradition. It took a few youthful and daring businessmen to get the ball rolling.

    TOKYO, June 8 (Xinhua) -- The Beijing Organizing Committee of the 2022 Olympic and Paralympics Winter Games held a promotion event in the Japanese capital, Tokyo on Saturday to introduce the latest developments in preparation for the Beijing Winter Olympics.

    The promotion event, which used an exhibition wall and the "Charming Beijing" photo exhibition to showcase the preparations of Beijing 2022, was part of "Beijing Week", a series of activities to commemorate the 40th anniversary of the establishment of sister-city relations between Beijing and Tokyo.

    On the exhibition wall with an area of 33 square meters, Beijing 2022 organizers show cased five aspects including the Beijing Winter Olympics vision, Beijing's winter sports tradition, emblem( 2 í) of Beijing 2022, competition planning and the National Speed Skating Oval.

    At the same time, old photos of the Chinese and Japanese ice hockey teams echoed the 40th anniversary of the establishment of sister-city relations between the two cities and the theme of the Beijing Winter Olympics.

    The promotion videos of the Beijing 2022 emblems, as well as other related video clips, drew great interest of the audience.

    The "Charming Beijing" photo exhibition displayed some of the Winter Olympic venues, showing the progress of the preparations for the Beijing Winter Olympics.

    Meanwhile, sand table, VR glasses and the "Beijing Winter Olympics Brochure" are also provided to let the audience visually experience the unique charm of the National Speed Skating Oval and the features of other competition venues.

    Chang Yu Director General of the Media and Communications Department of the Beijing Winter Olympic Organizing Committee, introduced the progress of the preparations 2022 and the vision of cooperation between Beijing 2022 and Tokyo 2020.

    Chang Yu said that the Beijing Winter Olympics Organizing Committee stays committed to with the aim of delivering a hosting the Games in a green, inclusive, open and clean manner, with an aim of delivering a fantastic, extraordinary and excellent Olympic event to the world.

    The Beijing Winter Olympics will open on February 4, 2022, which will feature sports, 15 disciplines and 109 events.

    Picture this: You're searching the Internet and come across a website with interesting articles. Some are news stories. Their goal is to share information. Others only look like news stories. They're actually advertisements, or ads. The goal of an ad is to get you to buy something. How do you, the reader, tell the difference between a news story and an ad?

    Back when I was growing up, it was easier. We got most of our information from newspapers. Big news stories appeared on the front page, and ads were boxed off and clearly labeled. But on the Internet, the two are often presented together. It can be hard to tell which is which.

    That's why the research group I direct conducted a study. My research team showed kids like you the home page of a popular digital magazine. We asked them to tell us what was a news story and what was an ad.

    Most were great at identifying certain types of ads. "It has a coupon (优惠券) code, a big company logo, and the words 'limited time offer'," one student wrote about an ad on the site. So where did kids get stumped (难倒)？

    Some ads seem identical to real news stories. They have headlines and contain information. But they may also include the words "sponsored content". Sponsored means "paid for," and content refers to the information in the story. "Sponsored content" is a way of saying that something is an ad. Most kids in our study, even if they used the Internet often, didn't know this.

    Something sponsored doesn't necessarily mean it's false. It means someone paid money for it to appear. Companies pay so that readers will see their stories, buy their products, and like what the company stands for.

    As a reader, you have a right to know who's behind the information you're consuming. So, look for the phrase sponsored content. (And look carefully. Sometimes, it will be written in tiny letters.) The Internet is a vast sea of information. To use it well, we not only have to know how to swim but also how to avoid the sharks.

On the day the tornado hit, there was no indication severe weather was on its way—the sky was blue and the sun had been out. The first alert my husband, Jimmy, 67, and I, 65, got came around 9 p. m. , from some scrolling text on the TV Jimmy was watching. He ran upstairs to find me in our third-floor bedroom, and we changed the channel from the presidential primary debate I had been watching to our local Pensacola, Florida, station.

No sooner had we found coverage of the tornado than it was on top of us. It was the loudest thing I have ever heard. The bones of the house shook, and the power went out. Pink insulation flew into the room from a trapdoor to the attic, and the wind began to roar through the house.

I didn't know how or if we would make it down the steps. It felt as if there were no floor underneath me as the wind lifted me off my feet. I gripped the banister (栏杆) and tried to move forward, but this intense pressure held me in place.

By the time I reached the closet, the tornado had been over us for about a minute. Jimmy pushed me down to the closet floor, but he couldn't get inside himself because of the wind. I gripped Jimmy's arm. My knees and scalp were full of glass, but in that moment, I felt no pain.

All of a sudden, Jimmy lifted off his feet like people in tornadoes do in the movies. I thought he was gone. And then everything stopped. He landed on his feet. In those first quiet moments, I couldn't believe it was over. Jimmy said he'd go outside to check. "No," I said. "Don't leave me. "

Our neighbor says the storm lasted four minutes. In that time, four of the twelve town houses in our unit were completely destroyed. Of the houses left standing, ours suffered the most damage. Amazingly, none of us were severely injured.
