A student is learning to speak British English. He wonders: Can I communicate with Americans? Can they understand me? Learners of English often ask: What are the differences between British and American English? How important are these differences?

    Certainly there are some differences between British and American English. There are a few differences in grammar. For example, speakers of British English say “in hospital” and “Have you a pen?” Americans say “in the hospital!” and “Do you have a pen?” Pronunciation is sometimes different. Americans usually sound theirs in words like “bird” and “hurt”. Speakers of British English do not sound theirs in these words. There are differences between British and American English in spelling and vocabulary. For example, “colour” and “honour” are British, “color” and honor” are American.

    These differences in grammar, pronunciation, spelling and vocabulary are not important. However, for the most part, British and American English are the same language.

    What's more exciting than having a fresh hot pizza delivered to your door? How about having it brought to you by a robot? Thanks to Domino's Robotic Unit or DRU, that just became a reality! On March 8, the three-foot tall robot delivered its first pizza to some lucky residents in Brisbane, Australia.

    The fully autonomous DRU is the result of a cooperation between Domino's Pizza Australia and Marathon Robotics.The 450-pound machine that travels at a maximum speed of 12.4 miles an hour can traverse a distance of up to 12 miles and back, before requiring a battery recharge. LIDAR, a laser-based sensor technology similar to the one used in self-driving cars, enables DRU to detect and avoid obstacles, while traditional sensors, much like those used in vacuum robots ensure its path is safe as it heads to its destination.   

    The robot can fit up to ten pizzas and even has a separate cold area to accommodate drink orders.To access their fond, customers have to enter the unique code provided by the company.This is not only ensures that they pick up the right pizza, but also prevents the pies from getting stolen.

    Scientists expert additional DRU's to be ready for service in their various Queensland locations within the next six months. But don't expect these super cute robots to replace humans anytime soon. According to Domino's the DRU still needs extensive testing, which the company believes could take up to two years.

    And then there is also the issue of regulations.The public use of autonomous vehicles is still banned in most countries.But Don Meij, the CEO and Managing Director of Domino's Pizza Australia New Zealand Ltd, is not worried.He is “confident that one day DRU will become an   integral part of the Domino's family.”

    On November 14, 1902, President Theodore Roosevelt was on a hunting trip in Mississippi while trying to settle a line(边界) problem between Mississippi and Louisiana. Being an expert outdoorsman, he liked to hunt large animals.

    However, his hunt was going poorly that days, and he couldn't seem to find anything worthy of firing his gun. His followers, trying to help him, caught a Louisiana black baby bear for the President to shoot, but he refused. The thought of shooting a bear that was tied to a tree did not seem sporting, so he spared the life of the baby bear and set it free.

    A famous political cartoonist for the Washington Star, Mr. Clifford Berryman, drew a cartoon titled. Drawing the Line in Mississippi, which used the story of the President refusing to shoot the bear.

    The cartoon in the Washington Star showed Teddy Roosevelt, gun in hand, with his back turned on a pretty baby bear. Morris Michtom, owner of a Brooklyn toy store, got the idea from the cartoon and make a toy bear. Planning to use it only as a display, he placed the bear in his toy store window, and next to it placed a copy of the cartoon from the newspaper. To Michtom's surprise, he was surrounded by customers eager to buy it. He asked for and received President Roosevelt's permission to use his name for the bears that he and his wife made, and the Teddy Bear was born! Michtom soon made Teddy bears by the thousands. The money from selling Teddy bears made him, in 1903, form the Ideal Toy Company.

    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.

    Central Park

    Explore Central Park, one of the largest city parks in the world and one of the most famous symbols of New York. Let's have a look at its main sights.

    Central Park is New York's largest city park and one of the biggest in the world, with an area of 843 acres (about 3.4km²). This park is home to man-made lakes, waterfalls, grass and wooded areas. You will also find the Central Park Zoo, among other attractions in this greenspace of New York.

    Besides being the city's primary green lungs, Central Park is also a favorite spot for many New Yorkers. It is perfect for sunbathing, going for walks, or doing any outdoor sports. Something that we found curious is seeing so many people running with their babies in prams (婴儿车).

    On Foot or by Bicycle

    To get to know some of the wildest parts of Central Park we suggest walking. However, to get a general feel for the whole park, the best thing to do is hire a bicycle and enjoy the scenery.

    Convincing someone to change their mind is really the process of convincing them to change their tribe (部落). If they abandon their beliefs, they run the risk of losing social ties. You can't expect someone to change their mind if you take away their community too.

    The way to change people's minds is to become friends with them, to combine them into your tribe, to bring them into your circle. Now, they can change their beliefs without the risk of being abandoned socially.

    The British philosopher Alain de Botton suggests that we simply share meals with those who disagree with us: "Sitting down at a table with a group of strangers has the incomparable and odd benefit of making it a little more difficult to hate them without punishment. Prejudice and conflict between groups of people from different nations or races feed off abstraction. However, during a meal, something about handing dishes around, unfolding napkins (餐巾纸) at the same moment, even asking a stranger to pass the salt makes us less likely to hold the belief that the outsiders who wear unusual clothes and speak in distinctive accents deserve to be sent home or attacked. For all the large-scale political solutions which have been proposed to ease racial or cultural conflict, there are few more effective ways to promote tolerance between suspicious neighbours than to force them to eat supper together."

    Perhaps it is not difference, but distance that produces tribalism and unfriendliness. As proximity increases, so does understanding. I am reminded of Abraham Lincoln's quote, "I don't like that man. I must get to know him better." Facts don't change our minds. Friendship does.

    The Japanese writer Haruki Murakami once wrote, "Always remember that to argue, and win, is to break down the reality of the person you are arguing against. It is painful to lose your reality, so be kind, even if you are right."

    When we are in the moment, we can easily forget that the goal is to connect with the other side, cooperate with them, befriend them, and integrate them into our tribe. We are so caught up in winning that we forget about connecting. It's easy to spend your energy labeling people rather than working with them.

    The word "kind (family and relatives)" originated from the word "kin (old fashion of family and relatives)." When you are kind to someone, it means you are treating them like family. This, I think, is a good method for actually changing someone's mind. Develop a friendship. Share a meal. Gift a book. Be kind first, be right later.
