For a long time, the traditional method of identifying liars was to watch their body language, including facial expressions.

    What if the person appears to be nervous? Is the person unable to look me in the eye? Is he or she look around the room? What about other nervous movements, such as fidgeting（坐立不安）or shifting from side to side? Many people—from parents to police officers and airport security personnel—depend on this method. But does a person's body and face reveal the truth? Not according to a new study.

    Talking, it seems, is the best way to smoke out a liar. That is what researchers in the United Kingdom found out recently. Their investigation took place at one place where lying can get you into big trouble—an airport.

    The researchers asked volunteers to pretend they were real passengers and then lie to airport security agents. Some of the agents used spoke conversation-based methods to question these make-believe passengers. Others depended instead on the person's body language, like lack of eye contact and showing signs of nervousness. The agents talking with the passengers were 20 times more likely to catch the liars. The study found that these conversation-based techniques can help you recognize when a person is lying to you. Like many methods, this conversation method has a name. It is called Controlled Cognitive Engagement or CCE, for short.

    The British government partly financed this study. The American Psychological (APA) published the findings. Body language cannot be trusted. Using body language and facial expressions to catch someone in a lie is really hard. And it only works, seemingly, by chance.

    Thomas Ormerod is the head of the School of Psychology at the University of Sussex in England. On the APA website, he reported that the “suspicious-signs method”—or using body language—“almost completely fails” in finding lies.

    Here are some of the smartest animals in the world.

Pigs

    Pigs are actually very smart animals. Pigs are one of the cleanest if they are given a choice. If you provide them with enough space, they will make sure they separate their dining area from their living space. Studies have also shown that they can actually be good at video games. To get food, they will follow other pigs and then steal it from right under their noses. The victimized(受害的)pigs will then come out wiser from this. They will change their behavior next time to prevent other pigs from stealing from them.

Crows

    They are smart and creative, with the highest IQ among all birds. Crows have been known to throw nuts and shells on a road so that cars will drive over and open them. They also have the ability to make knives to cut leaves and grass.

Elephants

    They have extremely large brains, even bigger than humans'. They bury(埋葬)their dead families and friends properly, the only other animal to do this besides humans. They also know which leaves are medicinal and will eat specific plants depending on the sickness they are feeling. They also have the ability to recognize themselves in the mirror.

Bottlenose Dolphins

    They actually have the ability to watch television on the their own because of their ability to process acoustic and visual(视觉和听觉)information at the same time. They can also recognize themselves in the mirror, which they use to inspect their own bodies. Their comprehension skills are very high. Studies have shown that they even have the ability to choose the “I don't know” option during difficult tests.

    Even now, almost a year after their astonishing act of group heroism, the dozens of people who risked their lives to save two boys from drowning in Panama City Beach, are still remembered.

    The story began on July 8, 2017. Members of the Ursrey family, eight in total, were enjoying an evening together at the beach. As the sun sank lower on the horizon（地平线）, the two boys—Noah, 11, and Stephen, 8—took their skateboards and walked into the waves without the grown-ups noticing. When the boys were about 70 yards from shore, they realized that the ocean pulled them out to sea. After trying and failing to paddle（涉水）back, they started waving and screaming for help. But the lifeguards had clocked out for the evening.

    The boys had been struggling for several minutes when Brittany and Tabatha Monroe, a married couple from Georgia, wandered by. They didn't see the boys at first, but they heard them.

    They jumped into the water and easily reached the brothers, who were still in fairly shallow water. The woman reassured the frightened boys and seized their skateboards, telling them they would be safe and then discovered that they, too, were now in a world of trouble. They couldn't get back to shore and could barely and only occasionally hit the sandy bottom with their feet. After a few minutes, it was clear to the woman that they were all trapped in a terrible whirlpool.

    Then scores of tourists were walking to them, hand in hand, forming a line. Soon the first person held the woman's hand. In turn, her husband and the two boys joined her. The long line moved slowly until they were back to the safety of the beach.

    The rescuers call it the Human Chain. But it was the deeply “human” aspect of the rescuers' cooperation（合作）that made it so astonishing and successful.

Planning Your Family Trip

    Plan ahead to make your family trip run smoothly. Family vacations are cherished memories. Keeping children entertained on the road or during a flight, however, can be challenging. The best way to cut down on anxiety? Plan ahead.

    Avoid giving children snacks that contain sugar and caffeine. Sweet treats keep them happy and quiet for five minutes, as it fills them with unusable energy that will turn into crankiness (偏执) when the sugar wears off. Bring fun, small snacks like flavored baked chips, apple sauce, raisins, and granola bars—and top it off with a little protein like cheese sticks to keep the blood sugar levels nice and steady.

    Bring plenty of plastic or paper bags. This is the perfect time to put those spare bags around the house to use. Store them in your purse or pocket, as well as in the car. This is a quick solution for garbage, diaper wrapping or motion sickness.

    Avoid extra costs on bulk items you will need during the trip. When flying, purchase bulk items like diapers, formula, and wipes at your destination. In the past, it was convenient and free to check these items. Now, each checked luggage item costs $25 or more on average. When driving, do the opposite; take your bulk items to avoid extra trips to the store when you arrive, which can help you avoid impulse travel purchases.

    Bring a full change of clothing for each child. Keep these items within fairly easy reach. When a spill or mess happens, this will help parents avoid unexpected (and unbudgeted) clothing purchases.

    Travel planning can help make family vacations what they are supposed to be: Fun! What are some of your favorite strategies for saving time and stress while traveling with children?
