Up until a few decades ago, our expectation of the future were largely positive. Science and technology would cure all the ills of humanity, leading to lives of satisfaction and opportunity for all.
Now the utopia (乌托邦) has grown unfashionable, as we have gained deeper appreciation of the range of threats facing us, from natural disasters to deadly flu to climate change. You might even be tempted to assume that human beings have little future to look forward to.
But such negative attitude doesn’t make sense. The fossil record shows that many species have existed for millions of years- so why shouldn’t we? Take broader look at our species’ place in the universe, and it becomes clear that we have an excellent chance of surviving for tens, if not hundreds, of thousands of years.
So what does our deep future hold? Perhaps it may be easier to think about the question in long time periods than about the more immediate future. The potential evolution of today’s technology, and its social consequences, is astonishingly complicated, and it’s’ perhaps best left to science fiction writers and futurologists (未来学家) to explore the many possibilities we can merely imagine. That’s one reason why we have launched Arc, a new publication dedicated to the near future.
But take a longer view and there is a surprising amount that we can say with considerable assurance. As so often, the past holds the key to the future: we have now identified enough of the long-term patterns shaping the history of the planet, and our species, to make evidence-based forecasts about the situations in which our future generations will find themselves.
This makes the negative predictions of our future seem more likely to be temporary and unreliable. To be sure, the future is not all rosy. But we are now knowledgeable enough to reduce many of the risks that threatened the existence of earlier humans, and to prevent the lot of those to come.

Children with attention problems in early childhood were 40% less likely to graduate from high school, says a new study from Duke University.
The study included 386 kindergarteners from schools in the Fast Track Project, a multi-site clinical trial in the U.S. that in 1991 began tracking how children developed across their lives. With this study, researchers examined early academic attention and socio-emotional skills and how each contributed to academic success into young adulthood. They found that early attention skills were the most consistent predictor of academic success, and that likability by peers (同龄人) also had a modest effect on academic performance.
By fifth grade, children with early attention difficulties had lower grades and reading achievement scores than their peers. As fifth-graders, children with early attention problems obtained average reading scores at least 3% lower and grades at least 8% lower than those of their peers. This was after controlling for IQ, socio-economic status and academic skills at school entry.
Although these may not seem like large effects, the impact of early attention problems continued throughout the children’s academic careers. Lower reading achievement scores and grades in fifth grade contributed to reduced grades in middle school, thus contributing to a 40% lower high school graduation rate.
Social acceptance by peers in early childhood also predicted grades in fifth grade. Children not as liked by their first-grade peers had slightly lower grades in fifth grade, while those with higher social acceptance had higher grades.
“This study shows the importance of so-called non-cognitive’ or soft skills in contributing to children’s positive peer relationships, which, in turn contribute to their academic success,” said Kenneth Dodge, director of the Duke Center for Child and Family Policy.
The results highlight the need to develop effective early interventions (干预) to help those with attention problems stay on track academically and for educators to encourage positive peer relationships, the researchers said.
“We’re learning that student success requires a more comprehensive approach, one that includes not only academic skills but also social, self-regulatory and attention skills,” Dodge said. “If we ignore any of these areas, the child’s development struggles. If we attend to these areas, a child’s success may strengthen itself with positive feedback.”

There it was. A test of will power. I’m on a special diet with foods carefully selected for balanced nutrition and caloric value. A piece of cheese cake is not an option. So here was my dilemma: Should I not eat the cheese cake, feel dissatisfied and take out my frustration on the annoyingly skinny physical instructor at the gym? Or should I eat the cheese cake and work off the calories?
The latter seemed like a win-win solution. Not only would I get to enjoy the cheese cake, but I’d get an exercise session. And then it hit me: a delicate plan to use my cheese cake as an exercise incentive. I plated a thin slice of cheese cake and carefully walked it up the stairs and set it on my bedside table with a small fork. I put on my exercise outfit and went downstairs.
The appeal of the cheese cake got stronger so I launched my plan: I would run up and down the stairs and then back up again. My reward: one small bite of cheese cake. If I wanted another, I’d have to run down and up and down and up again. Off I went. Ah, creamy vanilla goodness without guilt. I wanted another bite so I quickly sprinted through another stair climbing run.
Admittedly, it is harder to enjoy the creaminess of the cheese cake when my tongue was dry from over-breathing. I placed a bottle of water next to the cake.
Down and up and down and up again. When I struggled over to the cheese cake, my hand bypassed the plate and went for the water instead. I didn’t want the cake any more. I wanted all this sweat and effort to do more than cancel the calories from cheese cake. I was exhausted and sure the cheese cake tasted fine but just not good enough to make me run up and down the stairs one more time.
My plan worked. Now, any time I felt tempted to indulge in a former favorite, I remembered my stairs trick.

The Grand Canyon (美国大峡谷) is an unfolding mystery. No photograph, however stunning, can do justice to the Grand Canyon. No account, however expressive, can describe it in sufficient detail. To appreciate its marvel, you must see it for yourself. To get you started on your journey, here are several things you’ll want to know before you go.
Crowds
About 6 million people visit the Grand Canyon each year. Fortunately, the park is spread over about 2,000 square miles, so there’s plenty of chance for peace and privacy. There are several ways to avoid the crowds. First, visit the park in spring, fall or winter. Second, avoid the busy South Rim in favor of the more peaceful North Rim. Remember, about 12 people die each year in the Grand Canyon. Causes of death include drowning, falling, overheating and “killfies” — selfie-related deaths.
Internet and cellphone
There is spotty internet and cellphone coverage in the North Rim and South Rim visitor centers and in some of the larger hotels, including El Tovar and Grand Canyon Lodge. But if you venture inside the canyon and wander in places such as Tuweep Campground, assume you’ll be isolated. Always inform a friend or family member about where you’re going and for how long.
Railway
Since the late 1800s, the Grand Canyon railway has carried passengers from Williams, Arizona to the South Rim’s train station. It’s a pleasant ride through Ponderosa pine forests and wide-open grasslands. You won’t see the canyon from the train.
Skywalk
In 2007 the Hualapai tribe (部落) approved the construction of Skywalk, a bridge with a glass walkway sticking out 70 feet into the canyon, at Eagle Point in Grand Canyon West. Tickets start at $69 per person, which includes shuttle bus service and access to Guano Point, Eagle Point and Hualapai Ranch viewpoints.
1.According to the passage, when is the busiest season for the Grand Canyon?
A.Spring. B.Summer.
C.Autumn. D.Winter.
2.Cellphone signals can be picked up in the following places EXCEPT ________
A.Visitor centers. B.El Tover.
C.Grand Canyon Lodge. D.Tuweep Campground.
3.How can you enjoy the view of the Grand Canyon to the fullest?
A.By visiting South Rim when it is hot and sunny.
B.By posting selfies on social media websites while visiting.
C.By taking the pleasant train ride across the canyon.
D.By walking on a glass walkway at Eagle Point.

Dear Tom,
How are you getting on? I don’t think this a good idea to travel a lot and visit as many places possible. Last July Bell pay a visit to Europe. Europe is very beautiful, but his holiday wasn’t very nicely. He visited several country, and was in each of the countries for only three days. He visited a great many of places of interest, and was always in a hurry. When he returned from Europe, he was very tiring. So I suggest you spent your holiday in a different way. You’d better travelled with a friend to one country and visit only one city, that will do good to your body and mind.
