Tobacco use is one of the main risk factors for a number of stubborn diseases, including cancer, lung diseases and cardiovascular(心血管的)diseases . On World No-Tobacco Day 2022, make your health a priority and quit smoking, second-hand smoke in particular!

World No-Tobacco Day

World No-Tobacco Day is celebrated every year on 31 May. This event, which was launched by the World Health Organization(WHO), has been observed each year since 1989 to raise awareness of the health problems that tobacco use can cause.

What is Second-Hand Smoke?

Second-hand smoke, or environmental tobacco smoke(ETS), occurs when non-smokers breathe in other people's tobacco smoke. The WHO states that second-hand smoke is responsible for 600, 000 premature(早产 的)deaths per year. Children exposed to second-hand smoke are more likely to suffer diseases like asthma, ear infections, pneumonia and bronchitis.

While the consequence of smoking may seem far-off, they should be taken seriously. The WHO states that tobacco use is responsible for more than 6 million deaths every year, which is more than HIV/AIDS, TB and malaria combined.

What are the Health Benefits if I Stop Smoking?

Where Can I Get Help to Stop Smoking?

King Canute couldn't stop the ocean's tide from rolling in — can Africa hold back the desert? That's certainly what the continent is trying to do with its proposed"Great Green Wall", 8, 000km(almost 5, 000 miles)worth of trees that officials hope will stop the advancement of the Sahara Desert, which has been rapidly expanding southward.

The idea was introduced in the 1970s when the once-rich region turned barren(贫瘠的)due to climate change and intensive land use. But it's not a new idea; China has its own desert vegetation project to hold back the Gobi Desert!Thanks to the Chinese plan, the African project aims to plant 100 million hectares of trees by 2030 across the entire Africa. The initiative is a decade in, and around 15% completed, and there have already been benefits for many communities and wildlife. It's bringing life back to the continent's degraded landscapes at an unprecedented scale, providing not only food security and jobs but a reason to stay for the millions who live along its path.

The creators of the wall hope it will bring an urgently needed solution to the threats facing the African continent, creating 10 million jobs in rural areas, as well as preventing 250 million tons of carbon. The initia- tive is Africa-driven, which for those on the continent, is vital, and may hold the key to success. "The Great Green Wall …is about ownership, and that has been the failure of development aid because people were never identified with it, "said Elvis Paul Tangam, African Union Commissioner for the Sahara and Sahel Great Green Wall Initiative. "But this time they identify. This is the very thing of us!"

The wall may seem like a moonshot, but all the best ideas usually are. As Thomas Sankara, former president of Burkina Faso said in 1985, "You cannot carry out fundamental change without a certain degree of madness. The courage to turn your back on the old formulas, the courage to invent the future. "

Well, to pick up where we left off last time. I'm certain that you know all too well the dangers hiding on the World Wide Web. And whether it's for schoolwork, entertainment, or just socializing with friends, the Internet will surely be a major part of your child's life. So, it's important to secure their online stays.

It's not the easiest thing, but keeping open lines of communication is primary. Let them know they can share their online activities with you. Talk to them about their online presence as early as possible, ideally before they begin to use email, social media, or a smartphone. Discuss what they find interesting online and learning from them about popular websites and apps; this will create understanding and allow you to identify potential risks.

Next, monitor without spying. Most kids learn to understand boundaries, like respecting others'personal space, or not opening the cookie jar without asking. Internet use is no different. It's helpful for kids to have ground rules as to which websites they can visit, which apps they can use, and what they can share online. Remind them that if they feel uneasy with anything that occurs online, they need to alert an adult immediately. How you handle your kids'internet usage will depend in large part on their age. There are sites and browsing tools meant for younger kids, such as YouTube Kids, which aims to provide a safe online experience for children. Older kids may be allowed more freedom since they want to network and need to use the internet for information-gathering. But you can set boundaries that feel right for you. Just limit access appropriately.

Allowing your children to make good decisions online teaches them responsibility, shows that you trust

them, and reminds them that rules may be tightened if they disobey them. Stay tuned.

Whether it's a tricky math problem or an unexpected bill, daily life is full of stressful experiences. Previous studies have suggested dogs might pick up on human emotions, possibly through smell, but questions remained over whether they could detect stress and if this could be done through odor(气味).

Clara Wilson is a PhD student at Queen's University Belfast and first author of a new research. He and colleagues report how they first constructed a stand bearing three containers, each lid with a hole. They were able to train four dogs to indicate the container holding a particular breath and sweat sample, even when the line-up included unused gauze(纱布), samples from another person, or samples from the same person taken at a different time of day. Then the team turned to breath and sweat samples collected from 36 people asked to count backwards from 9, 000 in units of 17. The participants reported feeling stressed by the task and, for the 27 who carried it out in the laboratory, their blood pressure and heart rate rose.

The dogs were taught to pick out samples taken just after the task from a line-up that included two containers holding unused gauze. The researchers then tested whether the dogs could do the same when the line-up included unused gauze and samples taken from the same participant just before the task, when they were more relaxed. Each set of samples was shown to a single dog in 20 trials. The results reveal that the dogs chose the"stressed"sample in 675 out of the 720 trials.

"While it is unclear what chemicals the dogs were picking up on, the study has definitively proven that people, when they have a stress response, their odor profile changes, "said Wilson, adding the findings could prove useful when training service dogs, such as those that support people with post-traumatic stress disorder (创伤后应激障碍).

During the process of learning English, we students are bound to run across a variety of difficulties. When I was in senior high school, vocabulary was the biggest headache for me. There were always a sea of new words for me to cope with. Apparently, I couldn't interpret the hidden meaning of a complex sentence, much less a well-written text. Worse still, I couldn't memorize the new words. Hopefully, he offered me some important suggestions, which have helped me out. Here are some practical tips I'd like to share with you.

Read more. Be consistent. As well as improving your vocabulary, you'll also keep updated and backdated, your general knowledge will increase, and you'll be an intelligent, well-rounded person.

 Dive in. Read entries for words you aren't yet familiar with. This requires the ownership of a quality dictionary to make it more interesting, so look for a dictionary that has lengthy explanations on the origins and uses of words, as these will go a long way to help you remember the word and enjoy using your dictionary.

Try to guess the words in context. When you see an unfamiliar word, do not skip over it impatiently. Try to puzzle out its possible meaning in the context of the sentence, then look it up in the dictionary and confirm its definition.

As for memorizing the words, figure out the spelling rules and classify them in chunks.

Learning is endless. To be a lifelong learner definitely requires a lot.  Creating habits to help us learn and use the most accurate words in our language will make it easier to communicate, write, and think.

In ancient times, Chinese ancestors liked to steam or boil food. It was difficult for them to use spoons to get vegetables in the soup. So they (clever)invented chopsticks to pick up food. Development of chopstick has experienced a long history. Chopsticks only became two sticks of the same (long) in the Shang Dynasty(16th- 11th century BC).

As chopsticks feature the coming of civilization to food culture, the invention also (have) many scientific theories:The lever(杠杆)principle of mechanics is applied into practice . The point two sticks crossed is the pivot(支点)of the lever . An interesting experiment shows that many joints and muscles are being exercised you use it. They certainly make you cleverer, (do)they?

Chopsticks are small but they (admire)by many people in the world. Nowadays, chopsticks serve many new functions besides tableware. For example, you can buy a pair as a gift to your friends and rela- tives. In Chinese, it reads kuaizi, (mean)to have sons soon, so a newly-married couple will be very happy to accept it as their wedding gift.

I had been in a bad mood since my new neighbor moved in. I often typed articles on my computer. But no sooner had I become inspired to write than I could hear a girl singing next door.

She always sang this: "However hard the winds blow, you will stray(走失)no more from my company. We watch the meteor shower(流星雨)pouring down together. Your tears drop onto my shoulder. You shall believe that I am brave only for you, my dear. You will see a time of good cheer …"

She didn't sing well, and she was even out of tune, so it was absolute noise pollution for me. Sometimes, when I was just about to write, she started singing. This happened over and over. So how could I keep my spirits up and go on writing?

One day, I sat down in front of the computer and heard the girl singing again. It was too noisy and disturbed my thoughts. I had my husband go to complain about the noise.

Ten minutes later, my husband came back with a sad look, saying:"That girl is only 17, but she has bone cancer. Her mother said that the more painful it is, the louder her daughter sings. The singing helps her reduce her pain. Her poor mother begs our pardon again and again for her daughter interrupting us, "my husband said.

Immediately I was taken aback by his words. I said to my husband:"Please tell her mother that the girl can sing as much as she likes. We don't mind it at all. "

From that day on, I no longer thought the girl was doing anything wrong, and even got used to her singing. I felt it was like sniffing( 闻到)the smell of sunlight and watching the flowers and plants.
