A few years ago,I became very interested in what it meant {#blank#}7{#/blank#}(pause).I started to notice where pauses show up in my own work and life.For example,I realized when I was writing,a short walk was a(n) {#blank#}8{#/blank#}(effective)way to focus than concentrating harder.The small walk acted as a pause, {#blank#}9{#/blank#}(enable)me to rest,reflect or refresh,appreciate and break a block in my {#blank#}10{#/blank#}(creative).I realized that pause is not nothing!

New discoveries and technological breakthroughs are made every year. Yet, as the information industry moves forward, many people in society are looking back to their roots in terms of the way they eat. A "locavore" movement has emerged in the United States. The movement supports eating foods grown locally and sustainably, rather than prepackaged foods shipped from other parts of the world.

Experts hold that eating local has many merits, and is expected to become a trend featuring sustainability. Erin Barnett is the director of Local Harvest, a company that aims to help connect people to farms in their area. By eating local, she argues, people have a better and more personal understanding of the impact their food consumption has on the rest of the world. "There is a way of connecting the point, where eating locally is an act that raises our awareness of sustainable living," Barnett says.

The United States' agricultural output is one of the highest in the world, says Timothy Beach, a professor of geography and geoscience at the University of Texas in Austin, Texas. "There's just no other place on Earth where the amount of input is so productive," Beach says of American agriculture. "Nobody can cut off the food we need."

However, the US food system is not sustainable because of its dependency on fossil (化石) fuels, says Beach. Equipment used on "extremely productive" farms is quickly consuming Earth's natural resources, particularly oil. Additionally, the production of agricultural supplements (补充剂)，such as fertilizer, uses large amounts of energy.

The world has used close to half of the global oil supply, Beach says, and the second half will be consumed at an even faster rate because of the growing population and economic development. Although many businesses are experimenting with wind, solar, and biofuel, Beach says there's nothing that we see on the horizon that can replace it. "There is no way on Earth we are using fossil fuels sustainably. Then we have to reconsider the impact of eating local," he says.

One teacher had two students. One of them had a positive vision while the other had the 1 one.

One day, the teacher 2 for a park with both the students and while wandering in the garden, they 3 a mango tree from which some ripe and juicy mangoes were 4 . On seeing this, the teacher thought to 5 both of his students. Then, he asked the first one, "My dear child, what do you think of this mango tree?"

The student answered instantly, "Teacher, in spite of people 6 this tree with stones, it gives us sweet and juicy mangoes. It does 7 but still it gives us fruits. I wish all human beings learn this important 8 from the mango tree-to share their 9 even if they have to suffer for this."

After that, the teacher asked the other student the same question. The student 10 answered, "Teacher, this mango tree is no good and will not give mangoes by itself but only when we hit it with stones and 11 . Therefore, we should hit it hard to get sweet mangoes from it. That is the only way to 12 these mangoes. It is also clear from this tree that in order to get good 13 from others, we need to be violent and only when we become violent, then and only then will we get 14 ."

The teacher was delighted with the answer given by the first student because he had an admirable vision and 15 the tree with positive vision.

Intelligence is traditionally viewed as the ability to think and learn. Yet in a complex world, there's another set of cognitive (认知的) skills that might matter more: the ability to rethink. Therefore, my aim in this book is to explore how rethinking happens by seeking out the most convincing evidence and some of the world's most skilled rethinkers.

The first section focuses on opening our own minds. You'll find out why a forward-thinking businessman got trapped in the past, how a Nobel Prize-winning scientist welcomes the joy of being wrong, how the world's best forecasters update their views, and how an Oscar-winning filmmaker has productive fights.

The second section examines how we can encourage other people to think again. You'll learn how an international debate champion wins arguments and an African-American musician persuades people to abandon discrimination (歧视). You'll discover how a special kind of listening helped an officer convince the opposing side to join in peace talks. And if you're a Yankees fan, I'm going to see if I can convince you to root for the Red Sox.

The third section is about how we can create communities of lifelong learners. In social life, a lab that specializes in difficult conversations will cast light on how we can communicate better about debated issues like climate change. In schools, you'll find out how educators teach kids to think again by treating classrooms like museums, and approaching projects like rewriting time-honored textbooks. I close by examining the importance of reconsidering our best-laid plans.

This book is an invitation to let go of knowledge and opinions that are no longer serving you well, and to establish your sense of self in flexibility rather than consistency. If you can master the art of rethinking, I believe you'll be better positioned for success at work and happiness in life. Thinking again can help you generate new solutions to old problems and revisit old solutions to new problems. It's a path to learning more from the people around you and living with fewer regrets.

At the age of 12, I started playing golf when my parents enrolled me in a junior camp at the local public course. From that moment, much of my life has been 1 the game. The aspect of golf that attracted me was the sense of 2 . There's always a chance of making something 3 happen, maybe breaking a personal record or potentially making a hole-in-one. 

When I decided to pursue journalism in college, I had to take a 4 from the game. I'd still go out 5 to play with friends, but for the first time since my teens, I was away from my community. 

My 6 for playing golf reawakened when a friend invited me to the Langston course, which 7 me of the courses where I grew up: a 8 spot for people of all working-class backgrounds, and a far cry from the private golf 9 , in which expensive memberships are a basic 10 . When I get paired up with strangers to play, it's usually more of a 11 crowd. 

Some of the best walks I've taken have been out on the golf course. It's where I 12 with old friends and meet new ones, who 13 me to practice and get better. We share experiences on the golf course that are 14 and laugh about for days after our rounds. 

The sense of community I've regained with golf goes beyond my imagination. My circle only seems to be 15 , and I'm eager to see what the future holds.
