Do you know that November is National Novel Writing Month (NaNoWriMo)? You can find the NaNoWriMo Young Writer's program at ywp.nanowrima.org. It is a challenge（挑战）to write a 50,000-word novel in one month.

    The program began in 1999 in San Francisco with only 21 members. Later year, more than 400,000 took up the challenge. The writers can choose what they want to write about. On November 1st, writers visit the website and start to update（更新）their word count. They can communicate with other writers there as well. All the writers have to stop writing on November 30th.

    It is okay if you have never written a book before. The website provides lesson plans and workbooks for beginners. You can use them to improve writing skills in your novel. Then you can start planning what your novel will be about.

    Are there any books published（出版）from the NaNoWriMo program? Here are a few:

The Night Circus by Erin Morgenstern

Water for Elephants by SaraGruen

Entrychats by Cecile Duquenne

    Are there any young readers who want to join in this program? If you want, we hope you can write the best novel. If you have not heard of NaNoWriMo, but you have a good story in mind, join us!

    There's a new achievement in 3D printing that's beginning to come into focus: food. Recent development has made possible machines that print, cook, and serve foods on a mass scale(大规模地). And the industry isn't stopping there.

    Food production

    With a 3D printer, a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. Not everybody can do that—it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Foodini to "re-create forms and pieces" of food that are "exactly the same", freeing cooks to complete other tasks. In another restaurant, all of the dishes and desserts it serves are 3D-printed, rather than farm to table.

    Nutrition

    Future 3D food printers could make processed food healthier. Hod Lipson, a professor at Columbia University, said, "Food printing could allow consumers(消费者) to print food with customized(定制的) nutritional content, like vitamins. So instead of eating a piece of yesterday's bread from the supermarket, you'd eat something baked just for you on demand."

    Challenges

    Despite recent advancements in 3D food printing, the industry has many challenges to overcome. Currently, most ingredients (烹饪原料) must be changed to a paste（糊状物）before a printer can use them, and the printing process is quite time-consuming, because ingredients interact with each other in very complex ways. On top of that, most of the 3D food printers now are limited to dry ingredients, because meat and milk products may easily go bad. Some experts are doubtful about 3D food printers, believing they are better suited for fast food restaurants than homes and high-end restaurants.

    Most high school students would rather spend their summer vacations far away from the classroom. But Vineet Kosaraju and Nikhil Cheerla are choosing to go back to school, and this time they are the teachers.

    "I think it's really nice that I can help the community by spending just a little bit of time every week helping just a few students here and there try and learn programming," Kosaraju said.

    Friends since they were young boys, Kosaraju and Cheerla always shared a love of computer science. They learned the skills from their parents and school, but recognized that not all children have that chance.

    "Programming isn't taught in that many schools, especially low income (收入) schools, because there isn't that much money to support it," Kosaraju said.

    So he and Cheerla developed "Math and Coding," an after-school program for kids of all ages to learn the basics of computer programming.

    Between applying for college and doing their own homework, the two boys now spend a few hours every week going to different libraries teaching classes that cover everything from building basic games to developing apps.

    The friends started the program a little over a year ago and already, it's spread to more than a dozen libraries across the Bay Area in California. They are even training volunteers to teach these very same classes in other US states and Canada.

    Maryann Mitchell brought her 8-year-old granddaughter, Gabriella, to a class on coding at the Alum Rock Library in San Jose, California.

    "It's a chance for her to learn," Mitchell said. "It's the way of the future, and it's a good way for her to get grounded and be ready for what the future holds."

    "I think the most rewarding thing is having people come up and thank you and say they really learned a lot from this class," Cheerla said. "It doesn't get any better than that."

    Black Friday is the day after Thanksgiving Day and the Friday before Cyber Monday in the United States. It is not a federal holiday, but is a public holiday in some states. Many people take a day of their annual leave on the day after Thanksgiving Day. Some people use this to make trips to see family members or friends who live in other areas or to go on vacation. Others use it to start shopping for the Christmas season. Many organizations also close for the Thanksgiving weekend.

    Shopping for Christmas presents is also popular on Black Friday. Many stores have special offers and lower their prices on some goods, such as toys. Public transit systems may run on their normal schedule or may have changes. Some stores extend their opening hours on Black Friday. There can also be congestion on roads to popular shopping destinations.

    Black Friday is one of the busiest shopping days in the USA. There are two popular theories as to why the day after Thanksgiving Day is called Black Friday. One theory is that the wheels of vehicles in heavy traffic on the day after Thanksgiving Day left many black markings on the road surface, leading to the term Black Friday. The other theory is that the term Black Friday comes from an old way of recording business accounts. Losses were recorded in red ink and profits in black ink. Many businesses, particularly small businesses, started making profits prior to Christmas. Many hoped to start showing a profit, marked in black ink, on the day after Thanksgiving Day.

    The most famous war movies reflect the American public's continuous fascination with World War II and the Vietnam War. Many movies of this kind have been well-received when they were first shown, but few of them have enjoyed lasting fame and popularity. The films on the list of the five most famous war movies still remain fresh and are popular among many people.
