—A man ____ himself a popular singer. 

—I ____ to visit my grandparents in the country. While you are enjoying yourself on the beach, I ____ on the farm at that time. 

Who has no regrets about things done in the past? Wouldn't it be nice if, somehow, we could go back to change a couple of bad decisions? This sounds like science fiction.

The laws of physics prohibit traveling back in time for many reasons. If we did travel back in time and changed the course of events, we would be altering the course of history. An example often cited is the grandfather's paradox (悖论): If your grandfather died when he was still a high school student, he wouldn't have met your grandmother and your father and you wouldn't exist.

Putting humans or consciousness traveling back in time aside for the moment, is there anything in science even similar? Surprisingly, yes. At the level of quantum particles (量子粒子), there is something called Wheeler's delayed-choice experiments that show that actions in the present can influence the past. The experiments use something called the wave-particle duality (波粒二象性) of light and of matter. The fact that the physical nature of quantum objects is undetermined until it is measured. In other words, this means that a particle of light or of matter can behave either as a wave (spreading out in space) or as a particle (staying together) depending on the measuring devices. Long and ongoing discussions about the nature of quantum physics are still trying to work out what this actually means. Do our minds determine the nature of physical reality?

Should we offer food for thought for the future or the past? Unfortunately, these experiments say very little about how we could interfere with the past in events relevant to the human scale. Better to think carefully about decisions than to try to fix them backwards.

I had a younger sister, Michelle. But as a big brother, I rarely cared for her.

On a Sunday in March when I was 8, Easter(复活节)came. As usual, my sister and I would search for the hidden baskets full of candy and other things prepared for us. On that Easter morning, I got up early.

"Michelle!" I whispered to my sister, who was still sleeping in her bedroom. "Wake up. It's Easter. We have to go and find our baskets." She rolled over in bed and finally got up. "Mom and Dad are still sleeping, "I warned her as we walked out into the kitchen. "If we're quiet, we can find our baskets without waking them up."

It didn't take long for me to find my basket, which had candy, toys, etc. This basket was obviously mine because it contained the latest issue of my favorite magazine. My sister continued searching in every room while I dropped my basket off at the kitchen table and started separating candy into different categories. 20 minutes later, my sister told me, "I can't find it. I looked all over. Can you help me?" I decided to help her not because I felt sorry for her, but because I thought it was fun to find the missing basket.

We started searching through the cabinets(贮藏柜). Later, our parents were awake. Dad headed straight for the bathroom, while Mom walked out to make coffee. "Mom, I've found my basket," I told her. She smiled and asked , "Where's yours, Michelle?"

That's when my six-year-old sister started to cry. "Let's keep looking," Mom said, taking hold of my sister's hand. After searching the living room they went to the closet(贮藏室). There Michelle finally found her basket. But when she picked up her basket, we found everything in it had all been bitten and damaged by mice.

The arched timber lounge bridges (木拱廊桥) built in China nearly 1,000 years ago, still(stand) and still in everyday use, show the true skill of the master craftsmen who first constructed them. The amazing bridges,(suspend) between two banks of rich greenery and built from the wood of the trees surrounding them, are still a(full) functional part of life in Fujian Province and Zhejiang Province.

Of the 100 arched timber lounge bridges in China, the Qianshen Bridge in Shouning County, Fujian Province, which is an impressive 62.7 metres long and 4.9 metres wide, (rebuild) several times since it was built first. Now,remains an iconic image of ancient Chinese construction methods.

The bridges are built completely hand. The woodworking (master) design the bridges with range of arches depending on the surroundings, while the passageways can be various styles, depending on the use of the bridge.

To create arch support, "beam-weaving( 织 梁 )" is used in which three rows of wood formed an arch- supporting system while in the upper layer five shorter rows of wood(joint) and intertwined with upper-arch supports. Wood then connects the whole bridge is placed at the joints between the ends so the bridge becomes a solid whole. Traditional tools such as Lu Ban rulers, sawhorses, axes and chisels are used in the construction of the bridge.

Back in the days when I was just a young student, I was always absent from school events. My grades, though not absolutely good, was above the1 . However, an unexpected incident allowed me to2 life lessons and gradually accept the challenges thrown at me.

One rainy afternoon, an accident happened. A speeding car3 me, leaving me with a broken leg. Lying on my hospital bed, the reality of my situation4 . This unforeseen incident had set me back5 , and I needed to figure out how to achieve my previous6 .

With the help of my parents and teachers, who constantly7 me through the healing process, I managed to transform my8 into a stepping stone. I began to9 the will to push myself beyond my limits. After several months, I returned to school. My teachers had made accommodations for me, which included access to extra classes to10 the lessons I missed. Fueled by a newfound drive,I made every effort to engage in all activities and strived to stay11 in both the academic and extracurricular（课外的） fields.

In the end, my actions bore fruit. Not only did my academic performance improve, but I also developed an ability to adapt to unexpected situations. I realized the importance of being able to12 my fears and overcome them. The incident that I13 viewed as a major discouragement was, in fact, a turning point in my life.

The14 did not happen overnight. It was a15 process, just like adding a new piece to a puzzle every day. But with each piece, I moved one step closer to the bigger picture.

It is common for people to believe that by reading something over and over again they will learn it. However, repetition alone does not ensure learning. According to some reports, this is the most popular way students attempt to learn. However, mere exposure does not necessarily lead to better memory. What matters most is the approach taken when trying to learn the material. Here are some tips for effective learning.

Develop focused attention. Focused attention requires you to keep in mind what is important to your current goal. Attention is a skill; it can be learned. Research indicates various forms of mindfulness, meditation, and other strategies can lead to improved attention.

 All learning and memory formation is heavily dependent on brain health. Various types of exercise are beneficial for brain health. The foundations of brain health include exercise, nutrition, and cultivating positive social interactions.Nutrition recommendations include eating a balanced diet. Social interactions are good for brain health, but only when they are positive interactions.

Space your learning sessions. Memory is best when you spread your studying or training across multiple sessions. One of the key reasons that spaced learning increases memory is that each time you study, you may perceive the material from a different perspective.

A. Focus on brain health.

B. Practice challenging activities.

C. This may come as a surprise to many.

D. The exercise can vary from low to high intensity.

E. Memory reflects the ability to acquire information.

F. Learning is a process which is enhanced when it occurs over time.

G. Whatever you are learning, focused attention is a key requirement.

There are always unforeseen consequences when new technology is introduced. The truth is that the humans' depending on machines is even increasing. I've spent much of my life analyzing through written and spoken words. Now I'm a technologist making use of natural language processing for human good. Given that I work in Artificial Intelligence, I'm realizing something dangerous happening. Machines are destroying the way we communicate.

AI voices allow you to communicate verbally with your phone, they are normalized and yet cold, no matter which accent you tune your Siri or Amazon Alexa into. It's difficult to normalize language to be harmless and neutral because we all interpret meaning differently based on living experiences. Yet this is exactly what we're asking artificial intelligence to do for us on a billion-person scale. Once these rules are regulated by machine, they're inevitably create much bigger problems.

We noticed that there is an active desire to only neutral language in AI-powered tool. AI-powered recommendations let us autocomplete our thoughts in real-time. These functions are now key features in our emails, word processors and browsers. The machines are pushing us into a common tongue, and we accept it as a matter of convenience. You can press and hold the Power button for a second to wake up AI voice. But what's the cost? We are trading uniqueness and precision for convenience. We're also handing the power of acceptable speech to machine-controlled tools, not individuals.

In the physical world, we use words, phrases, tone, rhythm, humor and facial expressions to make us close and affective. We can tell where people were born based on their accents and phrasing. Humans are truly unique, and our communication is dynamic. So we should demand AI systems that promote individuality and uniqueness. The impact of AI voice will depend not just on what they can do, but also on how they make people feel.

Many of us have a secret, internal timeline we're always measuring ourselves against: the ideal age we'd like to get that degree, get married, reach a certain title at work. Our fantasy timetable hasn't evolved much over the years. A 2018 Stanford University study found that all generations agreed around 26 is the right age to get married, 27 the time to buy a house and 28 the moment to start a family.

What if it's not? Struggling to competing with the Boomers(生育高峰出生的人） in the job market and overwhelmed by rising social pressure, many millennial（s 千禧一代）just can't reach the milestones as planned.

Younger generations are increasingly pushing back everything from the age they start a full-time job to when they begin saving for retirement, says Laura Carstensen, director of the Stanford Center on Longevity. There are some downsides to the delay. Give up buying a home and you could miss out on a massive house. Put off saving for retirement and you may face financial insecurity down the line. You body might not be suitable to have babies forever, and it will age.

However, we're also living longer: 30 extra years, on average, over the last century. So, instead of rushing through all the big stuff, only to face a long period of stagnation at the end of our lives, why not spread out the milestones?

Working as a lawyer in Rochester, N.Y., Danielle Ponder would frequently Google, "Did anyone make it after the age of 35?" A gifted singer, she chose a career in law because she wanted the stability of steady work. She tried to make out some time for shows between court dates instead of committing to music full time.

Five days before her 40th birthday, she quit her job, which led to a bestselling solo album, television appearances and sold-out shows. "I don't know if I could make this happen to me at 19," she says.

Leo and Max Ordoñez came roaring into the wooded park and soon they're climbing up towering Douglas firs trees. The twins are joined by Leon Schwarcz, also 6, whose father, Joel, called out encouragement and kept a watchful eye on the young climbers.

Joel Schwarcz had a vision of turning the woods into a home for a treetop adventure park featuring platforms, bridges, and balancing. "My favorite thing is watching people come and look at the trees and go, ‘they maybe feel a little scared , but they'll try it out and go just a little ways up and then come down and just go a little higher and higher each time, seeing people's confidence grow as they are here for the hour and climbing." he said.

Park guests get a safety belt and instructions and soon are to climb up one of four routes: The Brothers, Mount Whitney, Mount Olympus and Mount Rainier. Green bands on the trees mark out 20 feet, reds mark 30 feet and yellows mark 40 feet. Climbers can choose a difficulty level by sticking to certain color holds.

"I live here in Kingston," he said, "and we've got a lot of great outdoor spaces but not a lot of opportunities for people to get out there and try something new without personally having the skill, so I wanted to bring something where people could just come on their own, and we give you the safety belt and instructions and then you're free to play in the park."

Schwarcz recommends that kids at a minimum be 5 years old, but the only set limits for the climbing systems are for weight. He notes that he has hosted both a 3-year-old climber and a 77-year-old climber at the park so far. "It's a great activity for all ages. " he said.

He added, "No matter how high they get, it doesn't really matter if you don't make it to the yellow bands, just seeing people grow has been really the most rewarding part of starting this. It's been super fun."
