Some beaches are perfect for relaxing, while others offer activities like hiking and water sports. Visit these beautiful beaches for an unforgettable vacation.

Cannon Beach

If your perfect beach vacation spot features postcard-worthy scenery and peace, look no further than Cannon Beach. In this Pacific Northwest town, you can even build a fire on the beach to relax beside while watching the sun set. When you need a break from the beach, grab a bike and head downtown to explore its art galleries, shops and restaurants.

Horseshoe Bay Beach

For a one-of-a-kind beach experience, head to Horseshoe Bay Beach on Bermuda’s South Shore. Known for its pink sand, this beach is a popular destination for families looking to play in the calm blue-green waters and build blush-colored sandcastles. Adventure seekers can also take part in the self-guided island bicycle tour or engage in exciting water sports.

Mohegan Bluffs

This beach is famous for its natural beauty. Upon arrival, pause to admire your surroundings and learn about its ties to the native people, their ancient traditions, and connection to the land, adding depth to your beach experience. Then, take the 141 steps down to the sand to sunbathe. After that, climb back up to visit the Southeast Light for an up-close view of its 18th-century lighthouse.

South Beach

This tropical district on Florida’s Atlantic Coast is world-renowned for its powdery white sand. Although technically part of the Miami Beach area, South Beach stands out due to its Art Deco architecture seen in everything from the beachfront lifeguard towers to the high-rise buildings along the famed Ocean Drive.

You are what you think. Whatever you are doing right now is determined by your thinking. All your emotions and desires are influenced by your thinking. The problem is that when you are not aware of your thinking, you have no chance of correcting it if it is poor. When thinking is subconscious, you are in no position to see any problems in it. And, if you don’t see any problems in it, you won’t be motivated to change it. What’s worse, few people realize the powerful role that thinking plays in their lives, so they don’t gain significant command of it. As a result, most people are in many ways victims of their thinking.

Consider your success as a student. The single most significant variable in determining your success as a student is the quality of your thinking. Your instructors will play a role in your learning, but even the best teachers cannot get into your head and learn for you. If you lack the intellectual skills necessary for thinking well through course content, you will not be successful in school.

Here is the key question we are putting to you in this book. If the quality of a person’s thinking is the single most significant determinant of both happiness and success, why not take the time to learn from the best thinkers?

This book will inform you of the tools that the best thinkers use and will illustrate the activities and practice you can use to begin to emulate them, and take control of your destiny as a thinker. Each chapter focuses on a different aspect of these thinking aids, helping you discover the power of your own mind and of your potential to think systematically about your thinking.

This book, as a whole, introduces you to the tools of mind that will help you reason well through various challenges you face. If you take these ideas seriously and practice using them, you can improve the quality of your thinking and ultimately, the quality of your life.

Human history is full of horse stories like guiding cowboys home on foggy nights and taking wounded soldiers through battle zones. Such sensible and highly trained horses made Elina Jatel, a computer scientist and roboticist, think of robots. “A horse that can take a rider home on its own would be the highest level of autonomy,” Jatel says. “You trust them with your life.” She was drawn to learning how such relationships form and if it could help improve human-robot interactions.

For a year, Jatel engaged herself in the horse world. She watched classes in horse training, and she also talked with students, instructors, trainers and horse owners. Along the way, Jatel even learned to ride.

Horses learn signals from their trainers on how to comfortably interact with people. People, too, must learn their part. Riders must learn what a horse wants or feels based on its behavior, and what signals to use to direct horses to perform in desired ways. Jatel found some similarities, here, to working with robots. People must learn how to direct robots to do specific tasks. They also must learn what to do when robots don’t perform as planned. The goal is to program robots that will respond predictably to inputs from people. But like horses, autonomous robots also should be able to respond on their own as conditions change. For example, a self-driving car must stop to avoid hitting something, even if some human mistakenly tells it to keep going.

Trainers and riders work with horses to build respect. Horses show that respect by matching their pace to a human or giving someone who is leading them a safe degree of personal space. Trainers begin their work with a horse by getting them to show signs of respect in basic interactions, Jatel says. Later, trainers will develop more complex interactions. Gradually, a horse’s respect can grow into trust.

But that trust is not given. And there may be a similar limitation with robots. What would it mean for robots and people to respect and trust each other? For now, she adds, this is largely uncharted territory. But she’s looking to build a path.

When we recall a memory, we bring back specific details about it. But we often also experience a vivid feeling of remembering the event. Memory researchers call these processes objective and subjective memory. A new study shows they can function independently and involve different parts of the brain.

“The study distinguishes between how well we remember and how well we think we remember, and shows that decision making depends primarily on the subjective evaluation of memory evidence,” says psychologist Denis Guetta.

The researchers tested objective and subjective memory. After showing volunteers a series of images of common objects, the researchers showed them pairs of images and asked them to determine which of the two they had seen before. They were asked to rate the memory as “recollected” (vivid and detailed), or “familiar” (lacking detail). Some tests showed similar image pairs, others unrelated pairs. This setup measured objective memory based on recognition and subjective memory based on vividness.

The researchers also used fMRI (功能性磁共振成像) to measure brain activity during this task. The results showed higher levels of objective memory with pairs of similar images, but participants claimed vivid memories more with dissimilar pairs. They were more likely to base their decision about whether to keep or clear an image on memory feeling rather than accuracy. For example, a person could have a vivid memory of going to an event with friends. Some of the actual details of that memory might be a bit off, but they may feel it is a vivid memory, so they might decide to go out with the same people again.

The fMRI data showed that objective and subjective memory engaged varied regions of the brain. The regions involved in subjective experiences were also involved in decision making, supporting the connection between the two processes.

“By understanding how our brains give rise to vivid subjective memories and memory decisions, we are moving a step closer to understanding how we learn to evaluate memory evidence to make effective decisions in the future,” says researcher Analiz William.

For most of history, people lived in small groups of up to 150 people. Then villages and small towns developed, offering safety and support through the sharing of resources. As time passed, urban living brought additional advantages such as better jobs, schools and healthcare. Larger towns also gave people more chances to meet and interact. This is important.     16    

Today, over half of the world’s population currently lives in towns and cities. But this has resulted in a strange paradox (悖论). Although social opportunities are one reason people choose to live in large cities, research suggests that city life can be lonely.     17     People from all over the world can join online communities and make virtual friends without leaving their home.

The development of virtual communities can be traced back to the 1860s. Back then, telegraph operators exchanged messages and gradually formed friendships over long distances.     18    

    19     Computers were not very powerful yet, so people could post messages and share news and stories but not music or photos. Still, people loved being able to make friends online and then hang out with them. As technology became more powerful, online communities for fun, education and business emerged, where people could explore a virtual 3D world, have online lessons, and even buy things with virtual money.

These days, there are thousands of virtual communities and that number keeps growing. Many people believe they will become more important.     20     Particularly, they’re concerned that posting personal information online might lead to a loss of privacy. So perhaps the future will be more like the past. People will spend most of their time in real communities.

I vividly remember the day when my husband and I set off on a new journey to Tanzania. He had been ______ a position there as a Civil Engineer. Accompanying him, my aim was to find a job shortly after. As you can imagine, I was very excited, even rather ______, as I’d never been abroad before. So, my first ______ was to get settled in this small town called Dodoma in the middle of Tanzania.

As we got off the train, however, at six in the morning, a lady came rushing along the ______ towards us. Completely out of breath, she said, “We’ve heard you’re from England and our school ______ needs an English teacher — please say you’ll help us.” I felt tired and ______ a shower after the journey. Though shocked by her ______, for some reason or other, I agreed to ______ it!

I washed, changed, had a quick bite to eat and was ______ to the two local teachers and my ______ at 8 o’clock. It felt like being thrown into the deep end, as my teaching timetable began ______ at 8:30! Although I’d hardly had time to get my breath, I never ______ my sudden decision.

Though my entry into this ______ was unexpected, I found joy in teaching those youngsters and gradually became part of the local community in the following years. I’ve been fortunate to ______ lifelong friendships, which has left a lasting ______ on both my students and myself.

More young people are trying their hand at farming the soil. Guo Lan, 29, works in a vegetable greenhouse on his organic farm     36     (locate) in the suburban district of Hefei, East China’s Anhui province. It is the eighth time this summer that Guo has failed to grow vegetables     37    using chemicals. Despite trying various homemade pest solutions, such as plant ash and mixtures of pepper and alcohol, the vegetable     38     (leaf) were still being eaten by insects. “I will not give up     39     (try),” the 29-year-old accountant-turned-farmer says. He is determined to turn his farm into     40     organic one, cultivating fruits and vegetables with the same flavors as those from his childhood memories.

“Growing tasty and healthy food     41     (be) my dream since I was a teenager. I know     42     challenging it can be, but if you take the soil     43     (serious), I believe it will pay off,” Guo says. He adds that farming is not a business that can make quick money, but for him, it has become an uplifting activity that brings back memories of spending time on the farm with     44     (he) parents as a child. Guo’s passion for organic farming and commitment to producing healthy food will surely inspire more young people to explore     45     (sustain) agriculture.
