Anyone who commutes(通勤)by car knows that traffic jams are an unavoidable part of life. But humans are not alone in facing potential backups.

Ants also commute—between their nest and sources of food. The survival of their colonies depends on doing this efficiently.

When humans commute, there's a point at which cars become dense(稠密)enough to slow down the flow of traffic, causing jam. Motsch, a mathematician in Arizona State University, and his colleagues wanted to know if ants on the move could also get stuck. So they regulated traffic density by constructing bridges of various widths between a colony of Argentine ants and a source of food. Then they waited and watched. "The goal was to try to find out at what point they are going to have a traffic jam." said Sebastien Motsch.

But it appears that that never happened. They always managed to avoid traffic jam. The flow ants did increase at the beginning as ants started to fill the bridge and then leveled off at high densities. But it never slowed down or stopped, even when the bridge was nearly filled with ants.

The researchers then took a closer look at how the behaviour of individual ants impacted traffic as a whole and they found that when ants sense overcrowding they adjust their speeds and avoid entering high-density areas, which prevents jams. These behaviours may be promoted by pheromones, chemicals that tell other ants where a trail is. The ants also manage to avoid colliding(碰撞)with each other at high densities, which could really slow them down. The study is in the journal eLife.

Can ants help us solve our own traffic problems? Not likely, says Motsch. That's because when it comes to getting from point a to point b as fast as possible, human drivers put their own goals first Individual ants have to be more cooperative in order to feed the colony. But the research could be useful in improving traffic flow for self-driving cars, which can be designed to be less like selfish humans-and more like ants.

(1)、How did the researchers control the traffic density of the commuting ants?
A、By finding out the dense points B、Through closer observation C、By controlling the widths of their path. D、By regulating their numbers
(2)、According to the research, ants can avoid traffic jams mainly because________.
A、they follow a special route B、they level off at high densities C、they never stop or slow down on the way D、they depend on their natural chemicals to adjust their speeds
(3)、What is the best title of the passage?
A、Traffic jams B、Unavoidable? Not for ants C、Survival of an ant colony. D、Difference between human and ants

    The Best Time to Visit These Pricey Destinations

    If you're going to shell out on a vacation, then you might as well do it right. With that in mind, we've asked a few experts for tips on when to visit some of the most expensive places across the globe. Here's what they had to say.

    Botswana

    Hotels in Botswana are second only to Dubai in terms of average cost per person, per night, at around $257. To make the most of your time there, consider an autumn visit, suggests Sarah Faith of Responsible Travel. “The heat peaks in October—this is the best time to go and see wild animals as they gather around in the Okavango Delta”, says Faith. While wildlife viewing is incredible in Botswana, there's much to enjoy away from the wilderness, too.”

    New York City

    New York is the second-most expensive holiday destination overall and the most expensive place to dine out, with an average meal for two costing around $67. Garrett, the CEO of Discover New York, suggests, “October and June have gorgeous weather, so outdoor activities are a good choice, with sailing, in-depth neighborhood walks and biking.” For great value, she advises traveling in January and February, when the city offers tons of indoor activities, from art galleries and Broadway shows to indoor sports events and thousands of dining options.

    Sydney

    With its incredible surfing beaches, dining scene and friendly locals, Sydney is always a favorite of travelers. It's also expensive. Generally, the shoulder seasons (fall and spring in the U.S.) have the most comfortable weather and fewer crowds than the December-to-February high season. But some months have particular appeal, according to Stuart Rigg, Australian travel specialist for Southern Crossings. April, for example, falls into the low season, which means you'll find hotel deals along with weather that's typically “very pleasant,” Rigg says. “Sydney also has some great events during this low season period,” he adds.

    London

    Petulia Melideo, who runs Context's London walking tours, advises booking well in advance for lower hotel rates, and suggests a wintry visit. “November is a great time for London. The weather is still tolerable—and if it gets too chilly, there are plenty of cozy pubs to pop into,” she says. Other good times to visit include June, which means fewer tourists.

    My timing has always been a little off with Elizabeth Strout. I've read and pretty much admired everything she's written, but, for whatever reason, the books of hers I've picked to review have been the good ones, like Amy and Isabelle andThe Burgess Boys, rather than the extraordinary ones, like Olive Kitteridge, which won the 2009 Pulitzer Prize. Anything Is Possible is Strout's latest book and it's gorgeous. Like Olive Kitteridge, Anything Is Possible reads like a novel constructed out of linked stories. In fact, it's hard to know exactly what to call this — a novel or a short story collection. In any case, these stories are animated (栩栩如生) by Strout's signature themes: class humiliation, loneliness, spiritual and, sometimes, reawakening. When Strout is really on her game, as she is here, you feel like you've been carefully lowered into the unquiet depths of quiet lives.

    Strout began working on Anything Is Possible at the same time she was writing her novel My Name Is Lucy Barton, which was published last year. Lucy, a dirt-poor child who grows up to become a celebrated writer, floats in and out of these interlocking stories. Some characters catch a glimpse of her being interviewed on TV; one travels to see her at a bookstore. An older Lucy even appears “in the flesh” in one story when she returns home to the small town in rural Illinois where most of these tales are set to visit her troubled brother; but Anything Is Possible also stands on its own. Indeed, a few of the characters here would be ticked off if they thought their stories depended in any way on that Barton girl. Strout's writerly eye works like a 360 degree camera, so that a character or place that's on the margins of one tale takes center stage in a later one. This technique sounds contrived, but Strout carries it off lightly.

    One of the most powerful stories here is called “Dottie's Bed & Breakfast,” which is an establishment we readers glimpse earlier in the book. Dottie desires to be middle-class and she harbors a grudge (怨恨) against life because she's had to rent out rooms to make a living. Dottie also possesses a sensitive nose for sniffing out the lower-class origins of some of her guests.

    “Shoes always gave you away,” comments a woman in a story called “Cracked” about a houseguest's too-high cork wedges(坡跟鞋). And, in the final story here, called “Gift,” a once-poor man made good says, “The sense of apology did not go away, it was a tiring thing to carry.”

    But, back to Dottie. When an elderly doctor and his wife come to stay at her guesthouse, Dottie bonds over tea with the wife, Shelley, who shares a story about a long-ago social humiliation.

    At breakfast the next morning, however, Shelley obviously regrets that confidence and becomes the Doctor's wife again. She freezes Dottie out and puts her back in her place as the inn-keep.

    There's comic satisfaction in seeing Dottie secretly spitting into the breakfast jam, but the more profound rewards of this story have to do with its recognition of the many varieties of human insecurity — or, as Lucy Barton herself more bluntly puts it, the many ways “people are always looking to feel superior to someone else.”

    Other stories have to do with sexual shame, or with the tragic ways close neighbors or family members misread each other; but I'm making Anything Is Possible sound too grim when, in fact, so many of these stories end in an understated (低调的) gesture of forgiveness. Strout is in that special company of writers like Richard Ford, Stewart O'Nan and Richard Russo, who write simply about ordinary lives and, in so doing, make us readers see the beauty of both their worn and rough surfaces and what lies beneath.

    People You've Never Heard of Who Changed the World

    It is a fact that most people live their lives unremarked by history. Whether by design or by accident, there are some pioneers whose achievements changed the course of history but whose names are unknown to us.

    James Harrison

    James Harrison has saved the lives of over two million people by donating his blood 1,173 times, a Guinness world record. His blood produces a rare antibody (抗体) which cures the otherwise deadly Rhesus disease in unborn children. It has also been used in the development of a medicine anti-D, which will cure the Rhesus disease in children forever.

    Lewis Latimer

    After helping Alexander Graham Bell obtain his patent for the telephone, Lewis Latimer patented a carbon filament (碳灯丝), which allowed light bulbs to burn for hours before burning out, much more useful than that invented by Thomas Edison. Latimer went on to invent many other useful devices, including a device which cooled and cleaned patients' rooms in hospitals.

    Maurice Hilleman

    Not all achievements require bravery and self-sacrifice. Take Maurice Hilleman for example. He found another way to change the world. He developed the mumps vaccine (疫苗) after his daughter got the illness. And he didn't stop there. In total, he has single-handedly developed over 40 vaccines, including eight commonly given to children. His work has saved millions of lives and prevented serious consequences due to the diseases.

    Nils Bohlin

    In 1959 Nils Bohlin patented a revolutionary design that has saved millions of lives-the three-point safety belt. After the initial resistance from drivers who hated being told what to do, and even for their own good, the three-point belt has become a standard feature in new cars around the world.

    "I feel unlikable, lonely and hopeless," said Lisa, a bright teenager from a loving home. "It seems that nobody wants to become my friend. What's wrong with me?"

    Like Lisa, many of us experience loneliness. The truth is that all people, no matter what their age or character — even the most outgoing, wealthy and popular — experience loneliness at least sometimes. It's healthy and natural to want to be around people who care. After all, we've all heard "No man is an island." That's true. We all need others in our lives.

    Solomon, the wisest man who ever lived, explains that if we want friends, we must be friendly and reach out to others. But it has risk. Because we are often afraid of rejection (拒绝), many of us are unwilling to reach out to others. We take a safer way and wait for others to make friends with us. But if we want friends, we've got to get beyond this.

If making friends is your goal as well, you need to consider taking some measures (措施).

    Be willing to take the initiative (主动权). If you see someone whom you would like to know, don't wait for her to make the first move. Get close to her and begin a conversation. Let her know in a non­aggressive (无攻击性的) way that you are interested in being friends with her.

    Reach out to those who are lonely. When you see someone at school sitting alone, go over and talk to her. And don't let popularity decide whom you reach out to. You'll often be surprised at the beautiful qualities behind a shy appearance.

    Ask questions. Start your first conversation by asking this possible friend what she likes to do or asking about her family. Be sure to ask questions that cannot be replied with "yes" or "no". For example, don't ask "Do you have a dog?" Instead, say "So, tell me about your pets." Avoiding asking "yes" or "no" questions makes your possible friend not end your communication with a one­word answer.

    Facebook was running my life.

    But what killed Facebook for me was when I posted a photo, and five minutes later my son asked me how many "likes" it had got. His question was a wake-up call.

    "Likes" are signs of acceptance and approval(赞同). I had forgotten that acceptance and approval need to come from within and had unknowingly set him a bad example.

    Before absorbed in Facebook, I spent a lot more time reading books and magazines. I checked in with friends through texts, emails and phone calls.

    To set a healthier example to my son, I deactivated my Facebook account.

    I'd been in the habit of checking Facebook many times a day, so I had to come up with some new habits. I carried a novel and a crossword puzzle book around with me. I rediscovered knitting. I started taking yoga classes.

    I started to remember a few things. My body is fine just the way it is. I have friends who will help me out when I'm in trouble, and I will help them out. I do my best to be a good mother, and our son is happy and healthy. We are very lucky to be able to afford two vacations a year.

    I stopped looking at the world through my cellphone. I felt completely present in the moment. The break left me feeling better about myself, my family, my home and my life.

    After a few weeks, I returned to Facebook. Now I look at the photos of my friends' kids growing up and treasure how social media allows me to keep in touch with family. I no longer have the desire to post updates often.

    It is not an addiction(上瘾) any more.

    The cost of living in countries like the U.S., Britain, Australia or France has skyrocketed in recent years. However, if you're willing to leave your country and explore life in other areas, there are many countries boasting an extremely cheap and low cost of living. Check out the following countries when planning your next move.

    Ecuador

    Ecuador is similar to the United States in many ways, and as a result has become a popular American getaway. They even use the U.S. Dollar for their currency. In this country, it's cheaper to eat out every day than cook for yourself on a budget in the U.S. You can even buy a property for around $50000 and hire someone to tend to it while you're away

    Mexico

    Although the country is known for its poverty ridden streets, there are many wealthier areas that provide every facility you might need. You can live off a mere $700 to $800 a month in Mexico, and this includes rent for a nice place, facilities, food, and any sightseeing.

    Argentina

    Argentina has been a popular tourist destination for many years. It has great restaurants, a rich history, and many places to explore. Not to mention, it's not very expensive to live here. A decent sized home can cost around $139000, which is relatively cheap in relation to homes in the United States.

    Vietnam

    Vietnam has also become a popular tourist destination in recent years. There are many million dollar luxury homes by the beach, but you can find a modest fiat or small home for around $25000 to $50000 if you search in the right areas.
