Tulips(郁金香) are the national flower of Iran and Turkey. The European name for the flower is a misuse of the Persian word for turban(头巾), a mistake probably arising in the common Turkish custom of wearing flowers in the folds of the turban. Alternatively, the misuse may have arisen because this eastern flower, when not yet in full bloom, looks like a turban. In Persia, to give a red tulip was to declare your love for someone. The black center of the red tulip was said to represent the lover's heart, burned to a coal by love's passion.

    Originally growing in the Ottoman Empire (present-day Turkey), tulips were imported into Holland in the sixteenth century. When Carolus Clusius wrote the first major book on tulips in 1592, they became so popular that the tulips in his garden were stolen from time to time. As the Dutch Golden Age grew, so did this colorful flower. They were commonly seen in paintings and at festivals. In the mid-seventeenth century, tulips even created the first economics bubble（泡沫经济）, known as “Tulip Mania”. At that time, tulips were so expensive that they were used as money until the market for them crashed.

    Today, Holland is still known for its tulips and other flowers, often sincerely called “the flower shop of the world.” Tulips are planted in great fields of beautiful color, and transform the landscape into a sea of different colors. Tulip festivals are held throughout the country in spring. However, the most well-known tulip festival is organized in the Noordoostpolder, a province in the central Netherlands, each year. Held in the middle of the tulip fields, this flower festival runs from late April to early May. The Dutch people took their love of tulips abroad when they settled, and tulips and tulip festivals are now found in New York and Michigan, where the connection to their Dutch roots is still very strong.

    What makes one person more intelligent than another? What makes one person a genius, like the brilliant Albert Einstein, and another person a fool? Are people born intelligent or stupid, or is intelligence the result of where and how you live?{#blank#}1{#/blank#}

    We know, however, that just being born with a good mind is not enough. In some ways, the mind is like a leg or an arm muscle.{#blank#}2{#/blank#} Mental exercise is particularly important for young children. Many child psychologists think that parents should play with their children more often and give them problems to think about. {#blank#}3{#/blank#}38．__ If, on the other hand, children are left alone a great deal with nothing to do, they are more likely to become dull and unintelligent.

    {#blank#}4{#/blank#} According to some psychologists, if parents are always telling a child that he or she is a fool or an idiot, then the child is more likely to keep doing silly and foolish things. So it is probably better for parents to say very positive things to their children, such as “That was a very clever thing you did.” or “{#blank#}5{#/blank#}”.

A. A healthy body contributes to one's intelligence.

B. Parents should also be careful about what they say to young children.

C. What people want to express is like this.

D. The children are then more likely to grow up bright and intelligent.

E. It needs exercise.

F. You are such a smart child.

G. These are very old questions and the answers to them are still not clear.

    Last summer I got a real taste of Swiss life when I spent six weeks with a host family in the Bernese Alps.

    On arriving in Erlenbach where my host family live,I knew I couldn't have asked for a better setting: it was such a beautiful mountain village.

    And I couldn't have asked for a better host family,either.They made me feel like part of their family,rather than a tourist—I joined in my host family's day-to-day activities,whether helping pick berries in the garden or going to friends' houses.I wasn't only traveling around Europe seeing the major sights,but I lost myself in a different culture.

    While many Swiss cultures are similar to America's,there are lots of differences,too.For example,most Swiss leave their windows open—without screens—all the time.At first I thought all the bugs（虫子）were going to get in and eat me alive,and wondered why they didn't close the windows and turn on the air conditioner.But then I realized there weren't many bugs and I really enjoyed the fresh air.

    Probably my biggest shock was the language.I expected the Swiss to speak German,but they spoke a dialect called Swiss German,which has hardly anything in common with German.At times I was very frustrated（受挫的）because my three years of German did not help,but my bad mood did not last.Anyhow,many people knew English and were extremely willing to speak it.

    Signing up for a cultural exchange was probably the biggest risk I ever took,but it was also the most rewarding. When I left,I promised I would return to Erlenbach.There is more to Switzerland than cheese and watches.

    On Monday, my classmates and I heard that our astronomy teacher's mother had died. We were surprised that he was still teaching in school. My best friend was telling me that the teacher was trying to forget the pain of losing his mother and trying to be strong in the middle of teaching.

    The teacher was such a warm-hearted person and we figured that we should give him a lot of love and good cheer. That night after school, my best friend and I thought about our teacher as well as his beloved mother and then we came up with an idea.

    When we went back to school yesterday, we gave him cheer-up cards which we had taken time to decorate with flowers, hearts and peace signs. As we handed the cards to him, we could both see the light in his eyes. The smiles on his face showed how much he appreciated what we did for him. The whole atmosphere was very warm and loving, and it's hard to express in words.

    This morning, when we both went to see the teacher again, he was so happy, and gave us both a hug. This made us feel that we just might have made his day, and that he was going to be okay.

    With that, I want to remind you to take the time to smile at the ones you love, be extra generous with hugs, kisses, things of that lovely nature! Life is so precious (宝贵的), so let us be happy and enjoy the gift of life.

    Visit the Newseum During "Museum Day"！

    Museum Day is an annual celebration of boundless curiosity hosted by Smithsonian magazine. Participating museums and cultural institutions across the country provide free entry to anyone presenting a Museum Day ticket. The Museum Day ticket provides free admission for two people.

    Here is some information about a popular museum — the Newseum.

    EVENT DETAILS

    Registration: free tickets will be available for the public to download on December 15 via the link: https://www.smithsonianmag. com/museumday/museum-day-2018/.

    Advanced registration is requested so that the museum sites know how many people to expect. If you don't register beforehand you may still be admitted the day of the event, but no guarantee for admission. All are welcome to attend including children and groups.

    Meeting Point #1: From 7:45 – 8:00 some volunteers will be in the Starbucks at 325 7th St NW before walking 2 blocks to the Newseum.

    Meeting Point #2: Outside the Newseum's Pennsylvania Avenue entrance. The Newseum opens at 9:00 am. However, as this is an extremely popular event we highly recommend arriving as early as possible, by 8:15 if you can, to bypass the masses that will show up later in the day.

    Meeting Point #3: Once the museum opens we recommend immediately heading to the 6th floor to avoid the masses since most people start on the 1st floor. On the 6th floor, the Hank Greenspun Terrace, which overlooks Pennsylvania Avenue and the U. S. Capitol, has one of the best views in Washington, DC. After that you can proceed through the museum's exhibits starting on the 6th floor and working our way down. The Newseum is open until 5:00 pm and guests are free to arrive and depart whenever they like.

    Director James Cameron went to new depths for his film-making on Sunday by setting the world record for the deepest ocean dive by a single person.

    This type of extreme research is nothing new to the director. Cameron, 57, is most famous for directing Titanic (1997) and Avantar (2009). During the several years of research for Titanic, he famously traveled to the bottom of the ocean to visit the sunken ship. He also visited the deep sea as research for his fictional 1989 film. The Abyss, which is about a submarine that comes across an alien species. "Most people know me as a film-maker," Cameron said. "But the idea of exploring the ocean has always been the stronger drive in my life."

    Cameron and his team had been preparing for the trip for seven years. On Sunday, Cameron took more than two and a half hours to make the dangerous 6.8-mile journey down to the Trench, an area with near-freezing temperatures, no sunlight, and heavy water pressure. Cameron traveled in a 24-foot-long mini-submarine he helped design, equipped with lights and 3D cameras for filming the adventure. It also had a mechanical arm for collecting samples of soil and deep-sea creatures. Humans had not visited the Mariana Trench since two divers first reached the deep-sea spot in 1960. The divers Don Walsh and Swiss oceanographer Jacques Piccard spent 20 minutes there but could hardly see anything. They took no pictures.

    In his well-equipped submarine, Cameron was able to spend three hours in the Trench, exploring and filming. He plans to use his recordings in a 3D film production for movie theaters and for a National Geographic TV special. "I see this as the beginning," Cameron said. "It's not a one-time deal. This is just the beginning of opening up this new frontier."
