Matthew Youlden speaks nine languages fluently and understands more than a dozen more. {#blank#}1{#/blank#} When I told Matthew how I've been working hard to only pick up a second language, he had the following advice for me.

    Know why you are doing it

    This might sound easy , but if you don't have a good reason to learn a language, you are less likely to stay interested over the long-run. {#blank#}2{#/blank#} Wanting to get to know a French person in his or her own language is another matter entirely. No matter what your reason is, once you've decided on a language, it's important to carry out .

    {#blank#}3{#/blank#}

    Matthew learned several languages together with his twin brother Michael. They learned their first foreign language, Greek, when they were only eight years old! Even if you can't get a sister or brother to join you on your language adventure, having any kind of partner will push both of you to always try just a little bit harder and stay with it.

    Have fun with it

    {#blank#}4{#/blank#}Think of some fun ways to practice your new language: make a radio play with a friend, draw a comic strip, write a poem, or simply talk to whomever you can. If you can't find a way to have fun with the new language, chances are you aren't following step four.

    Act like a child

    We learn by making mistakes. {#blank#}5{#/blank#}But as adults, mistakes become taboo(禁忌). Think how an adult is more likely to say, “I can't”, rather than, “I haven't learned that yet” (I can't swim, I can't drive, I can't speak Spanish). When it comes to learning a language, admitting that you don't know everything is the key to growth and freedom.

A. Find a partner

B. Leave your comfort place

C. We work in the same office in Berlin.

D. As kids, we are expected to make mistakes.

E. You are learning a language to be able to use it.

F. Using your new language in any way is a creative act.

G. Wanting to impress English-speakers with your French is not a very good reason.

    The Miami Planetarium (天文馆|) opened its doors to the public on November 4, 1966 and has entertained and educated children of all ages about astronomy and the wonders of the night sky ever since. The Planetarium houses a 65-foot diameter domed (圆顶状的) projection screen with 231 seats. At the heart of the Planetarium is a SPITZ “Space Transit Planetarium” star projector (放映机)， which is capable of accurately reproducing the stars and planets as seen from anywhere on Earth at any time during the year. Shows daily except Thanksgiving and Christmas Day. Unlike any other in South Florida, the Planetarium is a unique setting for bringing the stars and planets indoors in animated (动画) live star shows and music-filled laser light shows.

    The Weintraub Observatory (天文台) houses two powerful telescopes. Observatory hours are from 8:00 p.m. to 10:00 p.m. Look though the telescope to view the planets, the four moons of Jupiter, the rings of Saturn and deep sky objects such as galaxies, nebulate and double stars.

    Deposit (定金): A $75 deposit must be received 10 days prior to the visit date to guarantee your visit.

    Cancellation Policy: The museum requires 48 hours advance notice prior to any cancellation or other changes to a reservation. Without prior notification (通告) the original total will be expected upon arrival.

    Payment Policy: The balance of the admission fee is due upon arrival at the museum on your visit day.

    Upon Arrival: The leading teacher should check in at the box office with payment for the correct head count of students, and teachers. Visitors should remain on the bus until a museum interpreters show you around the museum.

Museum Etiquette (规矩): We ask that all groups remain together and orderly. Teachers are asked to help maintain order with their groups. We reserve the right to refuse service to any group or individual not obeying the museum policies.

    Bus Procedures: The museum will provide parking for buses in our parking lot. Upon arrival, bus drivers will be directed by the museum staff to the appropriate places to park. It is recommended that buses remain on the spots throughout the group's entire museum visit.

Preparing Cities for Robot Cars

    The possibility of self-driving robot cars has often seemed like a futurist's dream, years away from materializing in the real world. Well, the future is apparently now. The California Department of Motor Vehicles began giving permits in April for companies to test truly self-driving cars on public roads. The state also cleared the way for companies to sell or rent out self-driving cars, and for companies to operate driverless taxi services. California, it should be noted, isn't leading the way here. Companies have been testing their vehicles in cities across the country. It's hard to predict when driverless cars will be everywhere on our roads. But however long it takes, the technology has the potential to change our transportation systems and our cities, for better or for worse, depending on how the transformation is regulated.

    While much of the debate so far has been focused on the safety of driverless cars(and rightfully so), policymakers also should be talking about how self-driving vehicles can help reduce traffic jams, cut emissions(排放) and offer more convenient, affordable mobility options. The arrival of driverless vehicles is a chance to make sure that those vehicles are environmentally friendly and more shared.

    Do we want to copy — or even worsen — the traffic of today with driverless cars? Imagine a future where most adults own individual self-driving vehicles. They tolerate long, slow journeys to and from work on packed highways because they can work, entertain themselves or sleep on the ride, which encourages urban spread. They take their driverless car to an appointment and set the empty vehicle to circle the building to avoid paying for parking. Instead of walking a few blocks to pick up a child or the dry cleaning, they send the self-driving minibus. The convenience even leads fewer people to take public transport — an unwelcome side effect researchers have already found in ride-hailing(叫车) services.

    A study from the University of California at Davis suggested that replacing petrol-powered private cars worldwide with electric, self-driving and shared systems could reduce carbon emissions from transportation 80% and cut the cost of transportation infrastructure(基础设施) and operations 40% by 2050. Fewer emissions and cheaper travel sound pretty appealing. The first commercially available driverless cars will almost certainly be fielded by ride-hailing services, considering the cost of self-driving technology as well as liability and maintenance issues(责任与维护问题). But driverless car ownership could increase as the prices drop and more people become comfortable with the technology.

    Policymakers should start thinking now about how to make sure the appearance of driverless vehicles doesn't extend the worst aspects of the car-controlled transportation system we have today. The coming technological advancement presents a chance for cities and states to develop transportation systems designed to move more people, and more affordably. The car of the future is coming. We just have to plan for it.

    Emotional Intelligence by Daniel Goleman

    Did you know if your pulse rate rises above 100 bpm, you're considered too emotional to think rationally（理智地）? You probably let feelings cloud your judgment more often than you know. Goleman explains how you can avoid letting your emotions rule you and make better decisions in life.

    Some spiders hunt on the ground, others build webs to trap their food, but the grass water spider catches its prey by running along the surface of the water.

    This special water spider lives on the grassy banks of streams where mosquitoes, damsel flies and other insects come to feed and breed.

    Although it is one of the largest spiders in New Zealand, it has an unusual ability. It doesn't disturb the water as it waits for its meal, and there is barely a ripple(波纹) when it skims(掠过) across the surface at lightning speed to catch its prey.

    Grass water spiders deal swiftly with larger insects like damsel flies by pulling their heads under the water and holding them there until they drown.

    After a meal, the grass water spider spends up to half an hour grooming(修饰) itself. It wipes its eight eyes, brushes its antennae(触角), and takes special care to clean the hairs on its body.

    It is the hairs that trap tiny bubbles(泡沫) of air so that the spider can run down a blade(叶片) of grass and stay underwater for up to an hour when it is frightened. The hairs also keep the spider dry, even underwater.

    It is only when the female spider is caring for the young that she does not hunt on the water. After mating, she produces a large egg sac(囊), which she carries around for five weeks. Once the eggs start to hatch, she attaches the sac to some blades of grass or a thistle. She then tears the sac open and releases the tiny spiders into the nursery web.

Back in April 1939 and armed with $5,000 provided by the Rockefeller Foundation, professor Frank Cyr at Teachers College, Columbia University took a tour of ten states to make the research about school transportation problems. What he found was that many students had no dependable way to get to school and the ones who did often travelled in unsafe buses in the over 100,000 school areas.

Seeing a need to fix this problem, Cyr organised a meeting—one that would change the future of school buses forever. School officials and transportation experts met to set much-needed standards for buses, including those for colour, height and width as well as safety rules that hadn't been set before or that were different in every state.

There were many different bus colours in the US before this meeting; several areas even planned to have red, white and blue buses as a way of encouraging students to love their country. Cyr presented his new choice to education officials, a reported "50 shades( 色度) changing from lemon yellow to deep orange red". The matter was settled quickly. Yellow, or "National School Bus Glossy Yellow", was chosen because it was quite striking, making the school bus easy to be seen. Besides, it made the bold(黑体的), black writing on the side of each bus clear. (The bold, black writing gives information about each school area, telling students which school bus they could take during early morning and late afternoon hours.) Thirty-five states made the changes quickly, and every state took them on

board by 1974.

Being recognised as the "father of the yellow school bus", Frank Cyr has surely influenced your life if you ever rode a school bus or saw that noticeable colour pulling up to your stop on a dusky morning.
