    If cars had wings，they could fly and that just might happen，beginning in 2011.The company Terrafugia，based in Woburn，Massachusetts，says it plans to deliver its car­plane，the Transition，to customers by the end of 2011.

    “It's the next ‘wow' vehicle，” said Terrafugia vice president Richard Gersh.“Anybody can buy a Ferrari，but as we say，Ferraris don't fly.”

    The car­plane has wings that unfold for flying－a process the company says takes one minute－and fold back up for driving. A runway is still required to take off and land.

    The Transition is being marketed more as a plane that drives than a car that flies，although it is both. The company has been working with FAA to meet aircraft regulations，and with the National Highway Traffic Safety Administration to meet vehicle safety regulations.

    The company is aiming to sell the Transition to private pilots as a more convenient and cheaper way to fly. They say it saves you the trouble from trying to find another mode of transportation to get to and from airports：You drive the car to the airport and then you're good to go. When you land，you fold up the wings and hit the road. There are no expensive parking fees because you don't have to store it at an airport－you park it in the garage at home.

    The car­plane is designed to fly primarily under 10,000 feet. It has a maximum takeoff weight of 1,430 pounds，including fuel and passengers. Terrafugia says the Transition reduces the potential for an accident by allowing pilots to drive under the bad weather instead of flying into marginal(临界的) conditions.

    The Transition's price tag：$194,000.But there may be additional charges for options like a radio，a transponder or a GPS. Another option is a full­plane parachute.

    “If you get into a very awful situation，it is the necessary safety option，” Gersh said.

    So far，the company has more than 70 orders with deposits. “We're working very closely with them，but there are still some remaining steps，” Brown said.

    One Moore Elementary school teacher is showing students the importance of communication through “shout-outs”. Third Grade Moore Elementary teacher Lindsey Winders said a shout-out is a compliment（称赞）that students can say or write down. “Like, 'hey I noticed you doing a really great job solving your math facts yesterday. I wanted to make sure you know that I saw you do that,” Winders said.

    Winders said she makes sure she is giving shout-outs to her students every day. “I might write them a sticky note, or write them a quick little note in their plans. I might just say it to them on their way into the classroom or on their way out of the classroom, but most importantly I try to do it every day,” Winders said.

    In addition to the compliments, Winders has the students greet each other every morning during morning meeting. She will have students give examples to the class of how to communicate in different settings. Third grade student Nayelli Moranchel said she has given at least six shout outs this year. “It makes me happy, because they always write something back,” Moranchel said.

    Recently, Winders took it one step further and wrote a personalized note on each of her students' desk. “In our classroom, sometimes it can be challenging for me to give a compliment or a shout out to each and every one of them in a way that feels equal and valuable at the same time. So I thought what's a better way to be able to do that than leaving a note on their desk that can stay for as long as they want it.” Winders said.

    Winders said it is encouraging when she sees her students copy the act, and give each other compliments without her guidance.

    English is the most widely used language in the history of our planet. One in every seven human beings can speak it. More than half of the world's books and three quarters of international mail are in English. Of all languages, English has the largest vocabulary — perhaps as many as two million words.

    However, let's face it: English is a crazy language. There is no egg in an eggplant, neither pine nor apple in a pineapple and no ham in a hamburger. Sweet-meats are candy, while sweetbreads, which aren't sweet, are meat.

    We take English for granted. But when we explore its paradoes (探索它的矛盾), we find that quicksand can work slowly, boxing rings are square, public bathrooms have no baths in them.

    And why is it that a writer writes, but fingers don't fing, grocers don't groce, and hammers don't ham? If the plural of tooth is teeth, should't the plural of booth be beeth? One goose, two geese — so one moose, two meese?

    How can a slim chance and a fat chance be the same, while a wise man and a wise guy are opposites? How can overlook and oversee be opposites, while quite a lot and quite a few are alike? How can the weather be hot as hell one day and cold as hell the next?

    English was invented by people, not computers, and it reflects the creativity of human beings. That's why, when stars are out, they are visible (能看见的); but when the lights are out, they are invisible. And why, when I wind up my watch, I start it; but when I wind up this essay, I end it.

    Play is vital in every child's development, and for toddlers(蹒跚学步的小孩) the benefits of play especially come to life when they can connect with parents during playtime. To raise awareness and help parents create the time and attention span needed, LEGO and DUPLO launches a "Do not disturb playtime '' campaign. 21 days is what it takes on average to break a habit, so for 21 days the LEGO DUPLO team will not post on social media during "toddler playtime", defined as 5am-8pm.

    With social media being an integrated(不可或缺的) part and creative inspiration to modern family life, it is no surprise that researchers call out digital behavior as a concerning obstacle to quality playtime.

    "While we are hooked on our cell phones, we should think about turning them off when interacting with our young children. Kids learn so much from us and we don't want to get in the way of that. Take language learning for example. When nurturing caregivers talk to their children about what they are interested in, it helps them learn new words and new ways to express themselves. Our research shows that the use of a cell phone in a conversation between parent and child disturbs that child's word learning." advises Roberta Golinkoff, PhD: Professor, University of Delaware.

    Our research shows that parents today understand their significant role in ensuring their kids grow up to be happy, well-rounded, and equipped for the future. At the same time, many worry about not spending enough time with their toddlers. LEGO DUPLO wants to inspire parents to make the small moments memorable.

    "We know parents today feel more time-starved than ever before. Many feel guilty over not spending enough time with their little ones. Through the 'Do not disturb playtime' campaign, we hope to re-assure parents that it's not so much of the amount of time they spend with their kids, but the small meaningful moments they create during play", said Steffen Jensen, LEGO Group Senior Marketing Director.
