Before you go on your next two-wheeled adventure, make sure you're familiar with the ins and outs of bicycle safety. This holds true whether you're riding a traditional bike or an e-bike—one powered by an electric motor in addition to your pedaling. 

Many of the safety recommendations are the same for both types of bikes. Wear a helmet.  Make sure you're visible to motorists (some e-bikes now come with lights). Know how to use your arm to signal turns (left: extend your left arm out to the side; right: extend your right arm or bend your left arm up at a right angle). Don't talk on the phone, text, or listen to music. 

Be sure your e-bike is ready to ride. That starts with checking that the tires are inflated and the brakes are working properly. If the bicycle hasn't been used for a while, take it for a tune-up before you take it for a ride.  And before and after every ride, inspect your bicycle for damage. 

This is also important for e-bike riders. "With the ability to go faster comes the responsibility to know when you should slow down," says Ash Lovell, electric bicycle policy director at People for Bikes, a cyclist advocacy organization.

Know the rules of the road. "When you're riding in the street, even in a protected bike lane, read the signals, pay attention to the lane markings, and check the signage to see where e-bikes are allowed," Lovell says. Signs in those states may specify which types of bikes are allowed on which roads and paths. Check the People for Bikes website (peopleforbikes. org) for more information.

A. Do not ride on the left. 

B. Be aware of your speed. 

C. And if you're an e-bike rider, take notice of the following tips. 

D. Remember to replace batteries on a regular basis. 

E. Ride with the flow of traffic rather than against it. 

F. For an e-bike, also make sure your battery is charged. 

G. Thirty-six states have adopted a classification system for e-bikes. 

Spooky(幽灵般的) season is finally upon us! But it looks a little different to how it did 100 years ago. . . 

Halloween has been around for centuries, as a pagan(异教徒的) holiday in ancient Ireland during which people celebrated and "communicated" with visiting spirits. Initially Halloween was all about mischief, which may sound harmless, but used to have far more negative connotations. Before the 1930s, "trick-or-treating" was associated with groups of young men going door to door to play tricks such as throwing cabbages at houses or stealing garden gates.

Nowadays, trick-or-treaters tend to be children on the hunt for sweets. Going door to door for treats in Ireland was accompanied by the phrase, "Help the Halloween party". It was only in the 1980s that it became standard to hear choruses of "trick or treat", thanks to the classic 1982 film ET. As with many American cultural imports, not everyone was pleased about this development—in fact in 2009, The Telegraph ran the headline, "Halloween: Trick, Treat And A Total Travesty?".

In the 20th century, typical treats included candy apples, jelly beans and candy corn. These days, you are more likely to be met with Haribo Starmix and fun-sized Mars Bars (although if you are old enough to be reading Reader's Digest, you can probably expect to be turned away at the door should you attempt to go trick-or-treating this year). 

The most popular Halloween costumes have also changed in the last hundred years, shifting from cowboys and witches to Marvel superheroes. This year, after a Halloween night spent braving horror films and turning away children desperate for free sweets, you can at least sleep easy at night knowing that things have changed since the 1920s—and you'll probably wake up with your garden gate where you left it!

Back in April, Elon Musk, the world's richest man, made a dramatic attempt at a hostile takeover of Twitter, for a cool $44 billion. That's a lot of money, even for a billionaire tycoon(巨头), and the takeover attempt quickly slid into court battles. But whoever wins (we're not going to know for some time), I think the most interesting part of the story is the more fundamental question: why would Musk even want to buy Twitter in the first place?

If you look at the size of Twitter, its appeal isn't obvious. The company makes a relatively small profit each year, and in terms of the number of users, Twitter is a relative minnow among social media networks. It has around 436 million users every month, which isn't nothing—but is also a long way behind the likes of Facebook (near three billion), Instagram (two billion), and TikTok (one billion). So why does Musk want to spend a considerable slice of his own enormous fortune on a social network that not many people, in the grand scheme of things, actually use?

The answer might be what makes Twitter so interesting: what it lacks in revenue, size or growth potential, it makes up for in a much harder to define way. It carries absolutely enormous cultural power, and has an unrivalled ability to shape the news we read, the content we consume and the culture we live in. 

Miren Behaxeteguy, a 47-year-old from Montpellier, France, is one of the 41 million European adults who suffer from migraine(偏头痛). They can strike several times a week and leave her unable to work normally. Earlier this year, the pain forced her to take prolonged sick leave from her job as a social worker. 

"I hit a wall and decided I had to manage my pain in a different way," says Behaxeteguy, a grandmother. "I'm now focused on being comfortable before and during an    episode. "

As soon as she feels any pain surfacing, she puts on a hat containing ice packs and, on her neck, a grain-filled heat bag. She applies a variety of other prevention and management techniques, from relaxation to Pilates. 

Regular physical activity can prevent and ease aches and pains in multiple ways. It improves your general emotional well-being, triggers the release of pain-relieving chemicals, and boosts blood flow and nutrients to your joints and tissues. "Exercise is important not only because of the ‘use it or lose it' principle, but also because it increases confidence in your ability to do things," says Wittink.

If you're worried about worsening your pain or putting pressure on your joints, try gentle walking or low-impact exercises like tai chi or yoga. And if you've had a recent sports injury or are recovering from a surgery, a physiotherapist can often suggest at-home exercises that will help you to heal or improve your mobility. 

In addition to doing exercises suggested by her physiotherapist and going to Pilates classes, Behaxeteguy does deep breathing exercises with the help of online videos. "It takes five minutes, and I can do them anywhere on my phone. "

And, she puts great stock in the healing power of keeping pets. "Walking my dog helps me exercise and get some air, and my cat's purring(呼噜声) is incredibly calming. That's my personal prescription!"

China is a country well worth visiting. The following tips may make your trip to China pleasant and satisfactory. 

Which cities are preferable for tourists to visit on their first trip to China?

What you see depends on how long you can stay in China. Generally speaking, tourists should first visit cities like Beijing, Shanghai and Xi'an. 

Beijing is a political and cultural centre that offers great scenic attractions like the Forbidden City and the Summer Palace. Besides, foods such as Beijing roast duck and instant-boiled mutton have proved popular with tourists. 

Shanghai, a shopping centre for best buys, is the largest city in China. Tourists will be satisfied with what the city supplies, from various snacks and cakes to handicrafts and textiles. Neighbouring Suzhou and Hangzhou are considered by Chinese to be "paradise on Earth".

Xi'an, the starting point of the ancient Silk Road, was the capital of many dynasties in the Chinese history. The city is rich in tourism resources such as Great Wild Goose Pagoda and the Huaqing Hot Springs. 

When is the best time for the trip?

China is a vast land with great contrasts in landscape and climate. Consequently, tourists may pay a visit anytime. Spring and autumn are supposed to be the best times to tour cities like Beijing, Shanghai and Xi'an. 

If you dislike the cold, you can visit Kunming in south China, which is known for its year-round spring weather. A closer look takes you to the Stone Forest and the Dianchi Lake. If you rarely have a chance to see snow, Harbin is a best choice in January and February. 

What is well worth purchasing in China?

China has won a worldwide reputation for handicrafts, silk, porcelain and textiles, all more reasonably priced and of greater variety than elsewhere in the world. Unique local creations are available in their own cities. If tourists are not able to reach these cities, most of these products can be purchased in the Friendship stores in big cities. 

If you buy antique objects, be sure to get your receipts and an identification seal before you go through the Chinese customs.

Five rules for a healthy life

Thanks to better health care, most people are living healthier and longer lives. It's even thought that in the future more and more people will celebrate their hundredth birthdays. Here are five rules for a healthy life.

⒈Get off the sofa!

Sure, it's comfortable to sit on the sofa and watch TV. But doctors say you should get off the sofa. 要保持健康，你每天至少应走10000步。In the past, people's jobs required more physical effort. They often had to walk for miles every day. When farmers were working, they were keeping fit at the same time. Think about it: Do you get the same amount of exercise today as they did in the past?

⒉Eat healthy food!

It's important to eat food that is fresh and natural, for example, fruit and vegetables. Fast food is not healthy. You should only have it once in a while. Eating too much of the wrong food will harm your health.

⒊Rest while you can!

When we were babies, we slept for much of the night. Teenagers do not need as much sleep as babies, but it's important for you to get about eight hours' sleep a night. At weekends, you've got more time, so use it not just for your friends, but for rest too.

⒋Don't worry. Be happy!

Many people believe that happiness is important for our general health. Sometimes it is not easy to be a teenager because of the difficulties of school, exams or friendships. If you're worried about something, talk to your parents or your teacher.

⒌Say no to smoking!

Yes, you knew I was going to say this! It's so important. Smoking is not cool. It is dangerous. It harms nearly every part of your body. Think about how your family and friends will feel, and think about what it will do to your health.

Zhao Yafu is an old agricultural（农业的）researcher in Jiangsu Province. He spends most of the year working （介词）the fields. 

Born in 1941, Zhao's childhood dream was to become （冠词）news reporter. When he was at college, Zhao saw how hard lives were in the countryside, （连词）he decided to do something to help. He began to teach agricultural science to the farmers in a primary (school) in the village. "The villagers needed someone to help (they) change their minds and learn new techniques（技术）," Zhao said.

Zhao kept on  (encourage) the farmers to use the new techniques and to plant new kinds of rice, which brought in a lot of money. As time went by, more new  (house) and roads were built in the village. And the villagers came to understand that Zhao  (real) wanted to help them. 

Besides working in Jiangsu, Zhao and his team are also  (active) in Western China. Since 2013, they have helped many farmers in Western China become rich. 

"I saw how poor villagers used to be, and I also see how they have (change) over the years. I will continue with my work if my health is not too bad," said Zhao.

Lots of people find it hard to get up in the morning and put the blame on the alarm clock. In fact, the key to easy morning wake-up lies in resting your body clockHere's how to make one. 

● In order to make a change, you need to decide why it's important. Do you want to get up in time to have breakfast with your family, get in some exercise, or just be better prepared for your day？Once you are clear about your reasons, tell your family or roommates about the change you want to make. 

●Rethink mornings. Now that you know why you want to wake up, consider re-arranging your morning activities. If you want time to have breakfast with your family, save some time the night before by setting out clothes, shoes, and bags. That's a quarter-hour more you could be sleeping if you bought a coffee maker with a timer. 

●Keep your sleep/wake schedule on weekends. If you're tired out by Friday night, sleeping in on Saturday could sound wonderful. But compensating on the weekends actually feeds into your sleepiness the following week, a recent study found. 

●Keep a record and evaluate it weekly. Keep track of your efforts and write down how you feel. After you've tried a new method for a week, take a look at your record. If not, take another look at other methods you could try. 

A. Get a sleep specialist. 

B. Find the right motivation. 

C. A better plan for sleep can help. 

D. And consider setting a second alarm. 

E. If the steps you take are working, keep it up. 

F. Stick to your set bedtime and wake-up time, no matter the day. 

G. Reconsider the 15 minutes you spend in line at the café to get coffee. 

Albatross (信天翁) is not a kind of bird. It is a collection of bird families. Some of them have short tails, some have black feet and some others have large bodies and wings. There are at least 12 different kinds of albatrosses, and the largest kind has 1.5-metre-long wings. 

Like other sea birds, albatrosses drink seawater. They mainly live on squids (鱿鱼) and fish, and they sometimes follow ships to eat rubbish. Besides, they may also dive (俯冲) into water to catch their "seafood". One kind of albatross can dive as deep as 12.5 metres. Albatrosses spend most of their lives flying and can reach faraway places. They are also able to stay in air in windy weather for hours. Some large albatrosses have trouble keeping in air when there is no wind, and then they would rest on the water.

Most albatrosses live in the Antarctic and the North Pacific, and you can find them in Shandong, Taiwan and other seaside provinces of China. They give birth to babies by laying eggs. The mother albatross lays one egg every two years. The egg is taken care of by the parents in turn. 

Albatrosses are popular sea birds but their population is small. They are the first class protected birds in China. We should try our best to protect them.
