I was talking to my friend Sandy about our children. Sandy had recently moved into the neighborhood with her four kids: Jane, Joe, Christopher, and her youngest, eighteen-month-old Kim. She seemed happy to have kids nearby, until she saw our dog, Sam.

Sam, our shiny black dog, loved to play with the kids and protect them. But Sandy had a fear of dogs, and she started to back away as Sam approached. I grabbed Sam's collar and made him sit, trying to ease Sandy's discomfort.

Sandy mentioned that she needed to get her kids ready to go to their grandmother's house. Just then, her door opened and her kids rushed out. Sandy shouted at them to stay away from Sam.

The kids huddled(蜷缩) around their mom, looking at Sam cautiously(谨慎地). Emma, my daughter, showed the kids how to approach a dog slowly and properly. The kids were won over by Sam's friendly nature, but I knew it would take some time for Sandy to change her viewpoint.

After that incident, we made sure that Sam didn't go near our neighbors without me present. One day, when the kids were playing across the street, I noticed the eighteen-month-old baby heading towards a small hill. I saw a car approaching and shouted to everyone to watch the baby. Without hesitation, Sam rushed out the door and ran across the street towards the baby. He ran to the boy in time to gently push the baby away from the oncoming car. The kids cheered, completely unaware of the danger. They thought Sam had come to play.

Within a year, Sam had made friends with all the neighbors. Even Sandy started to warm up to Sam and would occasionally come over to give him a hug.

Are you a fan of outdoor adventures? Do you enjoy scenic views to relax? Look no further, as the following destinations offer all that and more.

Athabasca Falls

Alberta, Canada

Water from the Canadian Rockies flows down into the waterfalls of Jasper National Park, creating a flow with wild energy. The falls are wheelchairs accessible, with a paved path taking admirers to a number of viewpoints. If visitors leave the path, they can explore both the upper and lower regions of the trail.

Akaka Falls Trail

Hakalau, Hawaii

A short half-mile hike is big on sights and low on hard activity. The well-kept ringlike trail guide visitors around to see a number of waterfalls, including the 442-foot main attraction, and beautiful local flora(植物群) among the famous landscape. Though there are no hills to climb, there are a number of stairways to go.

Nugget Falls

Juneau, Alaska

Located in Tongass National Forest about 12 miles from Juneau, the Mendenhall Glacier has produced Nugget Falls, a fan-like waterfall that leads into a lake. A series of short hikes allows for different views of the waterfall and icy surrounds, which are also known for frequent brown bear sightings.

Yosemite Falls

Yosemite Valley, California

Yosemite National Park is one of the oldest national parks in America and home to the fifth tallest waterfall in the world. Hikers can reach it by taking a 1-mile trail from the lodge or the 7.2-mile round-trip Yosemite Falls Trail route. Late spring is best, with the highest water flow. In the winter, the temperatures dip below freezing. A park admission fee applies.

Tom and Jane planned a holiday at the lake, and they decided to take their children, Tim and Sarah, with them. However, Tim and Sarah wanted: to visit Disney World for their holiday or hire a yacht (游艇) in Hawaii. Camping by the lake wasn't even on their list of holiday adventures.

"We can visit some of the islands too, " Jane said. "Your dad and I always wanted to explore the mysterious cabin on Moose Island. "

Mysterious cabin? The children were now far more interested in this lake holiday idea. 

"We might see Big foot, " Tim said.

"Or some unusual species!" Sarah turned to her parents. "We're in. When do we leave?"

The children's excitement quickly disappeared when they arrived at the lake. While their parents were carrying their suitcases inside, Timand Sarah stood on the path and stared at the cabin they'd be staying in for the next week, complaining about the smell around, the dust, and the various small insects.

"We're in nature now, kids. Enjoy the experience! Your dad is building a fire so we can have barbecued fish and potatoes baked in the coals. Isn't that great?"

Sarah choked. "I am not eating food cooked in coals! I want takeaway instead. "

"Me too. " Tim was about to cry. "Holidays are supposed to be fun, Mom. "

"Come on, guys. There's a lot of joy to be found in living a simple life and spending time together as a family. "

"People in the suburbs live a simple life, which is more like being homeless!" Sarah shouted

"Yeah, " Tim added. "How can there not be a single restaurant that delivers here? How do these people survive?"

"They eat coal potatoes!" Sarah laughed. "And fish they kill with their bare hands!"

Sarah ran away, and Tim followed. Jane buried her head in her hands. She realized she had to do something to correct their children's attitude towards simple life. After dinner, she told all about this to Tom, who agreed with Jane. Then they came up with an idea.

Hong Kong actor Tony Leung Chiu-wai received the Golden Lion for Lifetime Achievement  the 80th Venice Film Festival on Sept 2. He made history as the first Chinese actor  (win) the award. 

The news created much (excite) in the film industry and across social media. It reflected the global (recognize) of Hong Kong cinema,  has been an important force in the film world. 

62-year-old actor said he wanted to share the award with all who have helped him during his 40-year acting career. The lifetime award recognizes the actor's rich collection of famous works. Since he became an actor in the early 1980s, Leung (become) famous globally for his performances in director Wong Kar-wai's award-winning films.

Famous director Ang Lee described Leung "a director's dream", (say)Leung can show complicated emotions simply through his eyes. "He can say more in one look than many actors can with a full monologue (独白), " Lee added.

Leung's next film, Silent Friend, will start filming in April 2024. Leung will play a scientist and work with a top film (produce)to show a story across different countries. The world's audience is looking forward to another fresh and touching performance by Leung.

Cruz Genet, 11, and Anthony Skop-ick, 10, couldn't agree. Were the birds out on the ice ducks or geese? So on a 1 January evening last year, the two friends ventured onto the 2 pond near their homes, to get a better look. First they tossed a rock onto the ice to 3 it. Then they stepped on it. 4 the ice would hold their weight, Anthony took a few steps, then…FOOMP. He crashed through the 5 frozen surface. "There was no sound, no crack, " he recalled, "I just fell through instantly". Cruz 6 to help his panicked friend. FOOMP-the pond. 7 him too.

The boys were up to their necks in icy water and quickly losing feeling in their limbs. Any chance of their 8 themselves was slipping away. Cruz was sure he was going to die. Anthony's older sister was nearby and started screaming for help.

John Lavin, a 9  driving nearby on his way home, heard her. He quickly 10 . Seeing the boys, he grabbed a nearby buoy (救生圈), 11  off his shoes, and ran into the slushy (融雪的) water, chopping his way through the ice with his free 12 . 

Lavin made his way to Cruz and Anthony and hauled (拉) them back to land. When in hospital, doctors discovered that their five-minute 13  in the water had lowered their body 14  nearly ten degrees. 

Fortunately, the boys have fully recovered, though they are still a little awestruck by their 15 neighbour. "Just to think, " says Cruz, "If he weren't there, we could have died. "

The Meaning and Power of Smell

Research into smell has never ended and in fact, there are so many interesting findings with regard to this sensation. Everyone knows that smell can cause strong emotional responses. In a survey, people were asked to report how they feel about a particular smell. Commonly, a smell connected with a good experience can please us, while an odour (气味) bonded with a bad memory may disgust us.  Such associations can be so powerful that odours generally labeled unpleasant become agreeable, and those generally considered sweet become disagreeable for particular individuals. 

One respondent believes there is no true emotional bonding without smelling a loved one. Infants recognize their mothers' odours soon after birth. Individuals were able to distinguish by the smell of clothing worn by their partners from similar clothing worn by other people.

Despite its importance to our emotional and sensory lives, smell is probably the most undervalued sense. While our olfactory (嗅觉的) powers are not as fine as those of certain animals, they are remarkably sensitive. 

Odours, unlike colours, can't be named in many languages because the specific vocabulary simply doesn't exist. "It smells like. . . , we have to say when describing an odour, struggling to express our olfactory experience.

 Smells considered offensive in some cultures may be acceptable in others. Therefore, our sense of smell is a means of interacting with the world. The study of the cultural history of smell is indeed an investigation into the essence of human culture. 

A. Odours are also essential signals in social bonding. 

B. Besides, odours are granted different cultural values. 

C Human's perception of smell facilitates the spread of human culture.

D. Our noses can perceive odours present in extremely small quantities. 

E. Nor can odours be recorded: there is no effective way to capture or store them over time. 

F. Some people's preference for a particular odour was influenced by their emotional wellbeing.

G. Yet, many people noted that their olfactory (嗅觉的) preferences were based on emotional associations. 

Despite all the efforts students make to graduate with a science major, research has shown that most college science courses provide students with only a fragmented (碎片化的) understanding of fundamental scientific concepts. The teaching method improves memorization of separate facts, proceeding from one textbook chapter to the next without necessarily making connections between them. 

With that in mind, we developed a series of cross-disciplinary (跨学科的) activities. In our most recent study, we investigated how well college students could use their chemistry knowledge to explain real-world biological phenomena. To begin with, we interviewed 28 college students majoring in sciences or engineering. All had taken both introductory chemistry and biology courses. We asked them to identify connections between the content of these courses and what they believed to be the take-home messages from each course. The students responded with extensive lists of topics, concepts, and skills that they'd learned in class.

Following that, a set of cross-disciplinary activities were designed to guide students in the use of core chemistry ideas and knowledge to help explain real-world biological phenomena. One activity explored the impacts of ocean acidification (酸化) on seashells. Here, the students were asked to use basic chemistry ideas to explain how the increasing level of carbon dioxide in sea water is affecting shell-building marine animals such as corals and oysters. 

Overall, the students felt confident of their chemistry knowledge. However, they had a harder time applying the same chemistry knowledge. The students in our study also reported that these activities helped them see links between the two disciplines that they wouldn't have perceived otherwise. The ability to make these connections is important beyond the classroom as well, because it's the basis of science literacy (素养). So we also came away with evidence that our chemistry students at least would like to have the ability to have a deeper understanding of science and how to apply it.

Today's Brussels sprouts(孢子甘蓝) taste better than you might remember from childhood, and that is because a new variety has replaced the original vegetable. You can thank plant breeders for the change. Modem breeders, armed with new gene-editing technology, are looking to reproduce Brussels sprouts' reinvention.

In the late 1990s, scientists discovered specific chemicals which made Brussels sprouts taste bitter. Plant breeders started growing old seeds, previously abandoned due to poor yields(产量), to look for tastier versions with lower levels of these specific chemicals. Then they crossed these delicious but low-yield plants with high-yield individuals until they found a version that made plenty of tasty sprouts, transforming the vegetable from a bitter pill into a popular dish. 

But other vegetables haven't fared as well. That's because most breeding decisions favor plant traits(特性) that matter to vegetable growers, not vegetable eaters. For instance, disease resistance is probably the major focus these days of most breeding programs because that prevents the farmer from growing the crop. The taste of vegetables is ignored.

People, however, are now becoming interested in prioritizing the taste of vegetables thanks in part to new genetic technology. "There's never been a better time to be a fruit breeder or a vegetable breeder because we have more tools and techniques, " says Susan Brown, an apple breeder at Cornell University.

Some companies are beginning to use those tools to deal with the challenge of developing tastier vegetables. One company, Pairwise, is fighting the same compounds that troubled Brussels sprouts. But this time researchers are improving the flavor of salad greens. 

All vegetable growers hope that more flavorful products on store shelves will convince people to consume the recommended allowances(定量) of fruits and vegetables—and do so better than decades of nutritional guidance have. "Don't waste your time talking about trying to educate people to eat better, "said Harry Klee, a professor who specializes in tomato breeding. "Just give them products that taste better and that they want to eat. "

As I walked into the George Eastman Museum's Dryden Theater, I felt as though I had stepped into a time machine. On the way to the traditional, old-timey box office, tons of vintage movie posters and the theater entrance made me feel like I was on Broadway. As everyone took their seats, an older gentleman who looked like he walked straight out of the 1920s gave the attendees a historical background of the film we were seeing-The Barker.

The film itself, which was released in 1928, is considered a "part-talkie". Before films included synchronized (同步的) sound, films were played with live accompaniment and contained subtitles to add context. With the invention of synchronized sound, films slowly added talking dialogue in scenes throughout the film; these films were considered "part-talkies".

The Barker, which explores the lives of carnival workers, is the talking debut (首次登场) of all of the main cast. The film was revolutionary not only for the technology but also for the actors. My film experience consists of mostly talkies, so when I finished The Barker, I felt like I witnessed something brand new for the first time. 

The experience I had at Dryden Theater was unlike any movie-going experience I had ever had. The music, the film, and the atmosphere itself were completely unique! Since viewing films has gradually been switched to streaming services, especially since the pandemic, this has both increased the accessibility of films and stripped us of reliance on a social experience to watch a movie-one that attending The Barker reminded me of. 

"Barbenheimer", a phenomenon that contrasts the obvious differences in the recently released movies Barbie and Oppenheimer, allowed us to return to the movie-going adventure. Finally, everyone wanted big screens and surround sound rather than the tiny screens in bedrooms. More importantly, we were all able to interact with a piece of content alongside other people. "Barbenheimer" brought back the pastime of going to the cinema-one that I think we should continue to engage in. I say we take a page out of the 1920s playbook and return to the cinema.
