China is a vast country where there is a lot (explore). But in the past two years, an increasing number of young Chinese travelers (prefer) to see their country from the sky.

The newest of these not-for-the-weak structures is called Sky Ladder (Tianti in Chinese), (lie) on Mount Qixing in Zhangjiajie Nature Park, in southwestern China's Hunan Province. It measures 551 feet in length and hangs between two cliffs a height of 5,000 feet, according to Chinese state media.

"The feet in this video are (I), and that kid is my son," said He Qian, whose Tianti climbing video has been widely recognized since it was posted online. Her video, she showed her feet on the ladder and then panned (摇动拍摄) over to her nine-year-old son sitting on the ladder calmly, gathered thousands of (like).

The sky-high attraction in Zhangjiajie sees an average of more than 1,200 tourists (day). Yuan Xiaorui, marketing manager of Qixing Adventure, the company that (run) the attraction, said, "The whole process will be accompanied by coaches. Tourists are required to wear helmets, safety belts and hike backpacks. The whole area is regularly checked and any problems (find) would be addressed in a timely manner," Yuan said.

My teacher and I would meet a few times a month to practice2 and go over grammar. During our communication, he also3 details of his life. Gradually, the4 of the first few lessons gave way to more familiarity and comfort. I stopped feeling embarrassed and began to open up about my own5 and my battle with Arabic. "Don't worry; I'm here to6 you. You're hardworking, and I'm sure you'll do well in it," said my teacher. I had7 my students with similar words in my own teaching. It was8 to hear them directed at me. The tables turned.

"You are9 today," my teacher would say when I used rich vocabulary or expressions. When I heard these words, I got a feeling of10. It also surprised me that my confidence could be encouraged by such11 praise. That was when I became aware of how12 I had praised my students, because I thought too much praise made them self-satisfied. But now, I had a change of heart and13 that these brief words can mean a lot. Words14. And now I become more15 when I use them.

Thinking how I would manage my entire day among strangers on campus, I pretended to be sick. Then I had the same feeling when I was planning to travel alone. Exploring a city on my own was a big fear for me but I successfully managed it all and now, I seek out new opportunities and experiences. I love to push myself.

Having grown up and lived all my life in a single place, I had a small set of friends since my school days which continued till my college days. I met a few very interesting people with whom I could feel an instant connect and got some new friends for life.

I totally agree that traveling with family and friends is fun and enjoying. But traveling alone is satisfying too. It's among those few things that you do for yourself and nobody else. During my solo travels I have explored my inner self and have expanded my boundaries which people around me have acknowledged at times.

A. I want to experience more.

B. But all this changed with my first solo trip.

C. I never thought I would travel alone in my life.

D. I was so scared when I went to school first time.

E. Every journey prepares you for the journey of life.

F. The farther you travel, the more independent you become.

G. After all you need to take care of yourself a bit too at times.

For years, public health officials have tried to limit the disease by controlling mosquito populations. "But that approach is short-term," says Anthony James, a professor of biology and genetics at the University of California, Irvine. "because mosquitoes are very tough little insects, and their populations can quickly increase."

Therefore, James and his colleagues want to try a different approach: making mosquitoes themselves into malaria-fighting soldiers, which is completely different from traditional ways of controlling malaria.

To understand how it works, it is helpful to first understand the life cycle of malaria. The malaria pathogen (病原体) is a parasite (寄生虫) that grows inside humans. It's passed through mosquitoes that move from person to person, sucking blood. "If we can make the mosquitoes difficult for the pathogens to survive, we can wipe out the disease," he says. But making mosquitoes unattractive to malaria is an extremely challenging task.

To solve the problem, the team used a gene-editing technique (技术) called CRISPR. They started with genes from mice, whose immune (免疫的) systems can fight human malaria, engineered those genes, and then gave them into the mosquitoes.

It turned out the gene-edited mosquitoes worked very well. They reduced the number of parasites in the mosquitoes before they were passed to a human host.

However, there is a long way to go. James' team are now working on planning a field experiment, which he hopes could be done on an island or another distant location.

But genetically changing wild animals does not sit well with environmentalists. "There's no need to engineer a mosquito," says Dana Perls, senior program manager for the emerging technology program at the non-profit Friends of the Earth. Perls points out that natural ways to reduce malaria appear to be showing promise, as does a new vaccine (疫苗) against the disease. "Why take unnecessary risks and use mosquitoes that can't be controlled once sent into the wild?" she asks.

Grocery store design is a carefully crafted art from both psychological and marketing standpoints, according to Reeves Connelly, who studied architectural design at the Pratt Institute. He explained there is a specific reason why fruit and vegetables are often located at the front of the store, "You'll grab the fruits and vegetables first and then hopefully feel less guilty about buying junk food later on." Meanwhile, essential items such as milk and eggs are placed at the back of the store to ensure customers walk through other aisles with many unhealthy options like snacks and sodas, potentially increasing the likelihood of impulse purchases.

There's also a reason why you often feel lost in local supermarkets. Shockingly, they move things around. Reeves explained, "They are very much aware that these strategies become less effective after you visit the store a few times and get a better sense of where everything is, so they'll regularly move the products to different aisles to con fuse you. The practice is not limited to a specific store but is employed across various retail chains."

"Their little tricks always work on me," one regular shopper admits, "I walk in to get three things and end up spending $300; that's why I hate grocery shopping," he said. On the other hand, some shoppers are proud to declare they have never fallen into the trap. "That's why I always keep a shopping list on me," another shopper shared. "I've started having my groceries delivered. If I have to go to the store, I never grab a trolley. If I can't carry it, I'm not buying it," he added.

Farming, however, was something I experienced later in life, in my teenage years. It's something I instantly connected with, and I feel fortunate that my children have been able to grow up helping out on the farm and spending lots of time with our livestock and pets.

It's so important to get a connection with farming at an early stage. We all eat food, so being familiar with where it comes from and what goes into producing it is a natural thing. If a spark of interest can be ignited early, it can only be a good thing going forward. It's a joy to see the children's faces light up on school visits when they see the photos of animals on our family farm and watch the video of an egg hatching (孵化). Animals have a unique magic all of their own.

Being around animals also teaches children what they can take with them into adulthood. It builds foundations of responsibility, kindness, as well as perseverance and problem solving. We work together as a family a lot on the farm, which builds a strong work ethic and a sense of teamwork — both fantastic life skills.

I'm a firm believer that you don't know what you're going to love until you try it. My hope is that if children from non-rural backgrounds get a taste of what it's like on a farm, then they might discover something they love.
