Today，by carefully choosing dog parents，humans have created many different kinds of dog Each kind has its own look and talents and its own role within human society.Here are three examples of "a dog's life" in the human world.
Today，many hospitals let specially trained dogs in to bring love and cheer to patients.Shaynee is a therapy（治疗）dog.She visits children who are in hospital.Dogs like Shaynee help patients feel calm and at peace which can be hard in a busy hospital.They help both children and adults stay strong during long hospital stays，and，some suggest，even help them get better.
Today some beagles（小猎犬）work in airports for the government They are part of the program called he Beagle Brigade.A beagle is good or the work because of its powerful nose，and ability to follow smells.The Beagle Brigade's job is to smell everything that comes into the country.They make officers notice illegal（非法的）fruits.vegetables，and other foods in luggage or in mail.The beagles do the job far better than any human could.
While some dogs are working hard others are free to spend their days resting and playing Across the world，many pet dogs are treated like children.Many have their own rooms and all the things a dog could want Some even have their own clothes.Many of these pets spend their days playing，learning to follow or even going to classes.Their owners give them the best，and enjoy doing so.
Whether as workers or objects of affection（钟情）dogs have become helpful to humans in many ways.There are plenty of advantages for the dog，too.Many kinds of wild dogs have nearly disappeared from the Earth.However，the domestic dog's special place as "man's best friend" has allowed it to survive （存活）in a human world.

British adventurer（冒险家） Alastair Humphreys had ridden his bike around the world，walked cross India，and rowed （划船）from Africa to South America.In 2011，however，Humphreys had some of the biggest adventurers of his life﹣and he never even left the United Kingdom.
For a year，Humphreys went on microadventures ﹣ small，low﹣cost trips close to home.Why did he do this？ "I started to think that it was possible to have an adventure anywhere." He explains.For his first trip，he went hiking with a friend around the M25﹣a 188﹣kilometre road that goes all the way around London.Other adventures included swimming in the River Thames，sleeping outside on a hill，and going on a mountain biking trip.Humphreys learned something important from his microadventures：We find adventures when we try something new.

Ever wondered why your virtual（虚拟的）home helper doesn't understand your questions？Or why your navigation app took you on the side street instead of the highway？In a study published April 21st in the journal Science，Italian researchers，Arianna Pipitone and Antonio Chella，designed a robot that "thinks out loud".
To explore how inner speech might influence a robot's actions，the researchers built a robot called Pepper that speaks to itself.It has the ability to reason and think.They then asked people to set the dinner table with Pepper according to etiquette（礼仪）rules.In one experiment，the user asked Pepper to lay the napkin at the wrong place，going against the rules.Pepper started asking itself a series of self﹣directed questions and concluded that the user might be mistaken.To be sure，Pepper confirmed the user's order，which led to further inner speech.
"Ehm，this situation troubles me.I would never break the rules，but I can't make the user unhappy，so I'm doing what he wants，" Pepper said to itself，laying the napkin where it was required to be.Through Pepper's inner voice，the user can learn Pepper was facing a difficult situation and solved it by prioritizingthe user's order.
Comparing Pepper's actions with and without inner speech，Pipitone and Chella discovered the robot had a higher task﹣completion rate when having self﹣dialogue.
However，some people find the robot spends more time completing tasks when it talks to itself.The robot's inner speech is also limited to the knowledge that researchers gave it.Pepper's designers still say their work provides a framework（构架）to further explore how self﹣dialogue can help robots focus，plan，and learn. "In some ways，we are creating a generational（世代的）robot that likes to chat.From navigation apps and the camera on your phone to medical robots in the operation rooms，machines and computers alike can take advantage of this chatty feature，" says Chella.

As a mountain，1，642﹣foot Squaw Peak isn't that impressive.But its views attract many hikers（远足者）.Henry Grant，a college student at Ithaca College，was one of them.
While waiting for his mother one day in August，2019，Grant watched other hikers enjoy the view.One hiker，dressed in pink，was looking over the lip of the cliff（悬崖）with her husband.
When Grant's mother rejoined him，the two continued on their way.Suddenly，he heard something scaring： "Paula!Paula!" a man shouted crazily.Grant turned around quickly.________
Several hikers immediately started looking for her，but their view was screened by trees.Uncertain they could help，Grant and his mother headed down the trail.But when he saw some hikers still searching，he decided to lend a hand.After promising his mother that he would be safe，he went on alone.
After 15 minutes of climbing over large rocks，pushing past bushes，and slipping（滑） down loose earth，Grant found a pink figure.The woman had fallen about 75 feet.Luckily，she was alive.
"Paula!Paula!" Grant shouted.The woman didn't reply.She was badly hurt.Grant called the police to report her location.She kept trying to move，and every time she moved，she slipped a little more.Afraid that in her unclear state of mind she might fall off the rock to her death，Grant climbed on all fours up a tight，narrow path by digging into the earth with his fingers and feet until he reached Paula.
Paula was moaning，almost senseless.Grant gently put her hand in his，trying to keep her mind off the pain by keeping asking her questions： "Where are you from？Do you have kids？" Soon， theywere joined on their perch（歇脚处）by another hiker named Simon.
