2 . Many factors in our life can lead to anxiety and stress. Luckily, there are several simple ways of relieving stress. Most of these steps are responsible for the improvement of your overall health as well.     1     Physical activity leads to a lowering of the overall stress levels and it also improves your quality of life both physically and mentally.

Any physical activity improves the capability of your body to use oxygen and it also leads to better blood flow.     2     Exercise increases the production of endorphins(内啡肽) in the brain. The endorphins are responsible for the “feel good” effect you feel and they also provide you with the much-desired “runner's high”. In simple terms, it is the sense of wellbeing people receive after performing the exercise.

    3     How do you choose the best physical activity for your exercise? There is no need for you to be an outstanding athlete or a long-distance runner to achieve stress relief. For instance, you can perform some aerobic exercise (有氧运动) such as jogging and dancing.     4     Doctors can help you develop an effective and safe exercise routine while taking into account your fitness level and the conditions you are suffering from.

Keep in mind that any kind of exercise will improve your fitness and reduce stress levels. You can also combine the activities till you have found the most enjoyable one. If you do not enjoy going near the water, never take swimming as a form of exercise. If the thoughts of running result in making you anxious, do not choose to train for a 5-kilometer race.     5    

Have you ever wondered how people type Chinese characters? The answer lies in the wonderfully useful phonetic system     1     (call) pinyin. It's the most commonly used system for spelling out the Chinese sounds, and it uses the letters in the Latin alphabet that you are already familiar       2     .

Pinyin is     3     extremely useful tool and should be the foundation of your Chinese learning. Besides, it's not just for Chinese learners like yourself.     4     (actual), all native Chinese speakers know pinyin,     5     is the first thing Chinese children learn at school before learning characters. So even if you don't know Chinese characters, you can type in pinyin and make     6     (you)understood.

Every single sound that exists in Chinese can     7     (display) easily in a pinyin chart. Once you master these 409 sounds along with the tones, you'll have practically mastered the pronunciation of every single word in the Chinese language. We've also created a series of video     8     (lesson)with practice tools that enable you to record yourself and listen back to it to     9     (sure) that your pronunciation matches the examples. Combined with our Tone Pairs practice tool, you now have everything you need     10     (master)pinyin, tones, and Chinese pronunciation.

6 . Wealthy nations need to give as much as ten times current levels of funding to help developing countries adapt to climate change, the United Nations said in a report.

If developing nations can’t adjust to climate change, rich countries will also feel the consequences, says Inger Andersen, executive director of the United Nations Environment Programme (UNEP), which prepared the report. “The idea that you can have a wall around your state and somehow protect yourself is simply unrealistic,” Andersen says. The report comes as world leaders prepare to gather for a climate conference. Organizers hope to make people realize the growing gap between current levels of aid for climate adaptation and what they say is required as climate shocks get worse.

Climate adaptation refers to steps to better protect people against the consequences of climate change— for example, moving communities away from coastlines and other areas. But much of the climate focus from rich countries’ leaders has been on limiting global warming by encouraging countries to burn less coal, oil and gas to reduce the emissions of carbon dioxide and other greenhouse gases.

At the United Nations climate meeting in Glasgow, countries promised to double the amount of funding available for adaptation to developing countries by 2025. But even if nations succeed in that, it’d still be insufficient for the need. Besides, it’s often spent in ways that aren’t likely to be effective over time, the report said. Adaptation efforts tend to be narrow, focus on short-term needs and fail to take future risks into account, it said.

The risk is that countries will soon experience climate shocks to which they simply can’t adapt, Andersen says. Relocation (搬迁), arguably the most extreme and expensive form of adaptation, will soon become vital, according to Andersen. “In most low-lying coastal areas, planned relocation is the last strategy,” Andersen says. “The longer wealthy countries kick this can down the road, the higher the price in human lives.”

7 . Over the decades, computers have affected our lives to an astonishing degree. When the first modern computer was conceptualized and built in the 20th century, it was so large that it took up a whole room. Over time, the technology shrank. First, computers became small enough to sit on a desk and be brought into the home. Then, they were made lightweight and portable, giving us the laptop. Today, most people have something even smaller: a smartphone that can fit into a pocket.

Though that's as compact as most people are used to, computers and technology are getting even tinier! One of the tiniest forms of technology available today is the microbot. A microbot is a very tiny robot -a machine programmable by a computer—that is built to perform specific tasks. You might tend to refer to this as just a small robot, but the size and dimensions of microbots are actually quite precise. A microbot is less than one millimeter in width, approximately the size of the tip of a pencil. In comparison, a small robot, which can be up to 100 centimeters in width, would be absolutely large. If you think that microbots are as small as you can get, think again. Nanobots smaller than one micrometer exist, but these are so small that they aren't visible to the naked eye(肉眼).

Since microbots are so small, they are potentially very cheap. Scientists and engineers working to develop these microbots believe that they could be used to explore environments or areas that are too small or dangerous for people.

Because the computing power of one single microbot isn't that large, microbots could be moved and used in large groups. At the moment, the biggest barrier to the development of these tiny machines is figuring out how to power a robot that can only contain an extremely small battery.

8 . The novel Restart was written by Gordon Korman and published in 2018. The book tells the story of Chase, a middle school student who loses his memory after an accident. At the beginning of the story, Chase gets knocked unconscious when he falls off a roof. When he wakes up, he can remember his name, but he doesn’t remember his past or his identity.

When Chase recovers and returns to school, he begins to learn about his own history through the reactions of the other students. As it turns out, Chase, once a star athlete, used to have fun hurting weaker students. Some people are afraid of him, some are angry with him, and some treat him like a hero. He finds that he doesn’t really like the people who used to be his best friends.

After his accident, Chase also has a different personality. He is no longer mean to other kids. However, everyone expects him to act the same as before. It takes time for the other students to learn to trust this new version of their old classmate. Each chapter is narrated (叙述) by a different character, so we get to hear every side of the story.

Gordon Korman has said that he enjoys writing for junior high school students because this is the age when kids begin to form their own opinions. In Restart, Korman addresses the themes of friendship, making mistakes, and getting a second chance. The novel explores the stories of a former bad guy and his victims, and gives readers a close look at the ways trust can be lost and rebuilt. The big picture comes together in little bits and pieces as each character offers their own details.

Everyone makes mistakes, and sometimes each of us would like to start over. In Restart, Korman shows us how to correct our mistakes and make it up to the people we have hurt.

9 . The road trip is an iconic (标志性的) American family vacation experience. Here are some road trips you can enjoy.

College Tours

If you are mapping out a college tour road trip with your teen, pick a region like the Boston area. There you can visit a mix of options that are large and small, public and private, and a mix of easy-to-get-into and reach-for-the-stars schools. Make the most of your visits by researching hotel stays that give you a taste of campus culture.

Road to Hana

To do this trip right you'll need 10 to 12 hours. The Hana Highway runs along a winding road dotted with 59 (mostly one-way) bridges and there are often a lot of crowds. But patience is rewarded with a large number of Mother Nature's finest offerings. Remember to stop at the roadside stands selling fresh fruit and banana bread.

Mount Washington Auto Road

Little kids get a kick out of the simple pleasures of leaf-looking, making a fall road trip through New Englanda perfect choice for this age. Add a little extra fun for the grown-ups by planning a side trip for this scenic drive in New Hampshire. Less than eight miles long, the road climbs 4, 600 feet above sea level along narrow mountain roads.

Pacific Coast Highway

This one is for you, tired parents. This stretch of Highway I running up and down the California coastline is an incredibly popular road trip for its breathtaking scenery —just the thing to relax your tired selves while your little ones sleep lightly in the back seat. From late October through February, you can also take your kids to the Pismo Beach Monarch Butterfly Grove, where more than 10, 000 of the butterflies migrate (迁徙) each year.

10 . Exploring Jaipur’s Art and Design Scenes

Still home to the royal family of Jaipur, this 300-year-old palace has lost none of its grandeur (壮观). The complex of courtyards, gardens and buildings is a mixture of Rajasthani and Mughal architecture. Among other things, the thoughtfully decorated museum houses an extensive textile (纺织品) collection, featuring rich fabrics as well as a carpet dating back over 400 years.

Anokhi Museum of Hand Printing

Situated in a restored old house, the Anokhi Museum is the perfect introduction to Jaipur’s textile industry. Information boards are excellently written, and the clothing on display is impressive. Don’t miss the on-site shop. Combine a visit with a trip to the UNESCO-listed Amber Fort, a remarkable walled castle that rises above the city and is only a five-minute ride from the museum.

Block Printing Project

Feel creative? A workshop is a great way to get a feel for the printing process. You’ll work alongside local craftsmen (工作), choosing your own blocks and colours. There are scores of companies providing the experience, but consider one of the sessions offered by the Wabisabi Project, which include a field trip and black tea to keep that creative energy flowing.

Jawahar Kala Kendra Centre

Just outside the Old City, Jaipur’s most important cultural centre was built to preserve Rajasthan’s rich heritage and master craftsmanship. Showing a wide range of both traditional and contemporary art, the space houses six galleries, as well as a museum, a library and an open-air theatre with programmes from plays to Indian folk dance. It also hosts its own theatre festival.
