    Researchers say getting a good night's sleep is probably the best tool for memory and learning. But short periods of sleep may help our brains work better, says a recent study on napping. And taking a nap  may also help old adults fight off age-related memory loss.

    CDC, an American scientific organization, found that 50 to 70 million Americans have chronic(长期的)sleep disorders. So, someone who naps as a way of paying off a sleep debt may not experience the same improvements from napping as a well-rested person would. Also, that only children, the very old, sick or  lazy people nap is not an uncommon opinion.

    Researchers recently looked at information provided by nearly 3,000 Chinese adults, aged 65 years or older, to learn if napping after a mid-day meal had any effect on the mental performance of the subjects.

    First, they asked the people if they napped and for how long. Then, based on their answers, researchers put them into four groups: non-nappers (0 min), short nappers (≦30 min), moderate nappers (30-90 min), and extended nappers (≧90 min).  Nearly 60% of the people said they did take a nap after lunch and that   their naps lasted anywhere from 30 to 90 minutes. Most of the subjects said they napped for about an hour.

    The study found that people who took an hour-long nap did much better on mental tests than those      who did not nap. The hour-long nappers also did better on the tests than those who napped for shorter and longer periods. In this study, it seemed that the most effective nap lasted for about an hour, but not much longer.

    Yet Doctor Michael Twery notes that an hour long nap may be too long for young, healthy adults. 30 minutes is enough to remove the pressure to sleep and will help us feel more awake.

    Today, I had the good fortune to join the students from East Silver Spring Elementary School in Maryland as they walked and biked to school in celebration of International Walk to School Day. I want to thank Principal Morrow and the entire ESS community for welcoming me so enthusiastically.

    Walk to School Day is a great opportunity for me to spend time with parents, kids, and teachers and to present our Safe Routes to School program and the First Lady Michelle Obama's Let's Move initiative(倡议).

    As a father, grandfather and former schoolteacher, I know how important it is that we provide students with safe choice to get to school while promoting exercise and healthy lifestyles. That's why I've embraced the Safe Routes to School program so wholeheartedly since I became Secretary of Transportation.

    You know, we're looking at an increasingly sedentary(久坐的)generation of children. One out of every three kids in America is now overweight. And I admire the First Lady's effort to end this within a generation. Safe Routes to School is a natural partner for Let's Move. For more than 10 years, Safe Routes to School has been making it easier for students to walk and bike from home to school. And ESS, where I walked today, is one of the earliest schools to participate.

    We know this program has been enormously effective because of the steady increase in the number of kids walking or biking to school. And as we made our way down the street this morning I was reminded yet again of this program's extraordinary work.

    Look, walking and biking to school is good for students' health. It's good for the environment. And it's good for the entire community's quality of life.

Everybody wins when kids take Safe Routes to School.

    As most people know, in the last few years, sandstorms have swept across many cities and areas of North China, polluting the air and disturbing daily lives of human beings. People look dirty and suffer many kinds of illnesses, such as breath difficulty. The sandstorm is such a serious problem that it has not only weakened the industrial and agricultural development of our country but also caused a lot of trouble to the living conditions of the Chinese people.

    Therefore, effective measures should be taken as soon as possible to stop its happening. So how should we deal with the frightening sandstorms?

    Some experts offer practical advice as follows: For one thing, more money ought to be put into tree planting and forest protection in order to keep more water on the Earth. For another, government of all countries should make laws on environment protection. For example, banning the use of throw-away chopsticks and punishing illegal tree cutting. Scientists should also study and find ways to lower the grade of its destruction and to improve the environment. As for some schools, education about sandstorms should be spread properly and timely to make more and more people attach great importance to this problem.

    How people look forward to sunny days with soft wind touching their faces now and forever! The golden days can come back so long as we try our best to protect the natural environment from today on. And the fact is that what I expect is not just a dream. There are some sweet fruits from the early efforts.

    Hadi Partovi, founder of Code.org believes every student should learn the basics of computer science just like they do math, physics, or biology, regardless of what they want to do in the future. The expert says knowledge about the subject is important to understand how the world around us works and compares it to learning about photosynthesis(光合作用), even though not every student is going to be a botanist. To spark students' interest, he created the “Hour of Code,” which introduces the world of computing to anyone, from ages 14 to 104, in a fun, interactive manner. Observed annually during Computer Science Week, the event now draws tens of millions of kids from over 180 countries.

    The “Hour of Code”, which can be scheduled anytime during Computer Science Week, begins with an introductory video on computer science. Participants can then select from hundreds of fun assignments that are sorted by both grade level and coding experience. Though each project is designed to last just sixty minutes, beginners can deal with as many challenges as they desire.

    To help introduce computer science in classrooms on a more regular basis, Code.org has also developed a catalog of online courses that can be incorporated(纳入)in a school's regular curriculum. Since the nonprofit began offering the courses in 2013, over 704, 000 teachers have signed up to teach introductory computer science to over 22 million students worldwide.

    Thanks to the efforts of the pioneer, about 40 percent of US schools now offer computer science as a subject. The numbers are even higher—an impressive 70 percent—if after-school offerings such as robotics clubs are included. Even more encouraging, eight years ago, just 19, 390 students took an Advanced Placement Computer Science exam. By the spring of 2017, the number had jumped 415 percent to 99, 868.

    Long Beach, a 28-mile stretch of beach, lies in southwestern Washington, and it is generally called Long Beach Peninsula (半岛). Communities there take you back to old days of a simple and slow-paced life style. Here, visitors can relax and enjoy the good of total rest.

    Bird Watching

    There are different kinds of birds in Long Beach. It is best if you observe them from a distance and do not try to frighten them. The Southwest Loop Trail Map can be gotten through the Long Beach Peninsula Visitors Bureau Office by calling 1-800-451-2542.

    Horses

    A popular activity in Long Beach is horseback riding. Two businesses in the city of Long Beach offer guided horseback tours along the beach: Back Country Wilderness Outfitters and Skipper's Equestrian Center. You may also bring your own horse. Among the adventures offered with horses is a wagon (四轮马车) ride along the beach, a carriage ride through Sea view or Long Beach, a back country (偏远乡村) packing trip, or a sunset ride by horseback on the beach.

    Camping

    RV (娱乐车) and tent camping aren't allowed on the beach, but there are private camp­ grounds and RV parks in the area, as well as Cape Disappointment State Park. Camp fires are allowed within 100 feet of the beach, but must be away from the dry grass.

    Swimming and Other Activities

    Swimming is allowed, but you must be careful. The waters are very cold and dangerous. Surfing is advised only for experienced surfers. Beach driving is allowed at certain spots on the beach. The speed limit is 25 mph. Building sand castles, digging sand to find something, bicycle riding, and flying kites are also popular activities in the area.

    You can find right hotels easily in the area. Enjoy your trip to Long Beach, Washington!
