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.

Governments around the world are pushing for an end to plastic straws （吸管） and bags.More and more businesses are turning to paper products as a choice.Paper is considered by many to be better than plastic.However，it，too，is harmful to the environment.
Firstly，paper bags and straws are made from trees.Trees，as you know，can reduce （减少） carbon dioxide （二氧化碳） levels in the atmosphere. Theycan slow down climate （气候） change.An increase in the use of paper bags can cause more acts of cutting down trees.
Secondly，products made from paper require more energy and water.About 10 percent more energy and four times as much water is used to produce a paper bag than a plastic one.You might say that we can use recycled paper to save that energy and water.This seems to be a good idea.However，it takes even more energy and water to go through the recycling process than to make a brand new paper bag.Products made from recycled paper are also often short﹣lived.
Thirdly，paper products are heavier than plastic ones.That means they require more oil to transport.Seven trucks are needed to transport two million paper bags，while only one truck is needed to transport the same number of plastic bags.The increased weight also leads to a large amount of waste once the bags are thrown away.
Paper products are actually a lose﹣lose for both the environment and businesses.They are more expensive than plastic products.A paper straw costs about 5 to 12 cents，while a plastic one usually costs only about 2 cents.
The most environment﹣friendly solution is to avoid single﹣use products altogether.Products like glass water bottles and steel straws can be used over and over again.They are much better than either paper products or plastic products.Through increasing the use of these products，you can greatly reduce your throwaway waste and truly make our Earth a greener place!

| A． |
Plastic products. |

When the wizard saw it，he came to Leo.Leo was very happy，though a little disappointed because his lion body had lasted only a short time.
"You are great." said the wizard， "But have you ever seen a lion fighting？No one fights with lions because they know how brave and strong lions are." Yes.Leo had never seen a lion fighting.He suddenly understood that he didn't really turn into a lion and that what really worked was his brave heart.

At the age of twelve，his father sent him to Harrow Public School，which was famous for training English gentlemen.Because he failed the entrance exam，he was placed in the last group of the class with worst grades.He fell behind the others in study.He gave many people the impression of low energy，strangeness ，and lawlessness. Fortunately，he still had a friend，his grandfather.The American of great wealth who had experienced the world said， "Let him go!As long as boys have the chance to show their talents，they are sure to become better." Churchill kept the words of his grandfather in mind，and secretly looked for it in his heart.
Many years later，Churchill was already a successful politician and writer.He worked as a reporter，as Secretary of the Navy，and as Prime Minister （首相） of the United Kingdom.He said， "My grandfather taught me that boys must choose their own path.I don't have special talents and my success is by working hard."

The natural world is colorful with humans，plants and animals showing different colors.
Human skin can be many different colors and it changes.with the sun，our feelings or our health for example.This is because of pigments（色素），which reflect light and make what the eye sees as colors.So，when we feel excited or angry，our heart can send more blood to the face and the pigments in the skin become red.This is why we have the expression that someone. "sees red"when they are angry.
Plants also have pigments.Color is important for them to live on.The bright colors of flowers catch the attention of insects（昆虫），which then carry their pollen（花粉）from one flower to another.Bees can see colors we cannot，and they follow these to the inside of the flower.Without bees visiting flowers in this way，many plants would die out.
Animals also use color for their own need.They protect themselves with different colors so as not to be seen by predators.The snowshoe hare for example，a type of wild rabbit，changes color with seasons for this reason.During summer it is a brown color，and in winter it is white so that it can hide in the snow.However，some animals use color as a warning to make predators stay away.Bright colors such as yellow and red are often used in this way.Nature，however，is very clever，and predators also use colors to attract（吸引）the animals they feed on..
So，we can see that there may be many different reasons and uses for colors in the natural world.Some uses of color in nature remain unknown；but one thing is for sure，color not only makes our planet beautiful but it is also necessary for our planet to live on.

"Have you finished your lesson，George？" said Mr.Prentice to his son，who had laid aside his book and was busy making a large paper kite.
"No，father，"replied George，hanging down his head.
"Why not，my son？"
"Because it is so difficult，father.I am sure that I shall never learn it.Besides，I could not remember it after I had learned it，my memory is so bad."
"If I were to promise you a holiday on the thirtieth of the month after next，do you think you would forget the date？"
"No，I am pretty sure that I should not."
"You are first﹣rate at skating，and flying a kite，and playing at ball and marbles，are you not？"
"Yes，father."
"And yet you cannot learn your lesson!My dear boy，you are deceiving（欺骗） yourself.You can learn as well as anyone，if you will only try."

"One of the dullest boys at a village school，more than thirty years ago，went up to repeat his lesson one morning；and，as usual，did not know it. ‘Go to your seat！' said the teacher angrily.
‘If you don't pay more attention to your lessons，you will never be fit for anything.'
The poor boy stole off to his seat，and bent his eyes again upon his lesson.
‘It is of no use；I cannot learn.' he said in a whisper to a companion who sat near him.
‘You must try hard，'replied the kind﹣hearted boy.
‘I have tried，but it is of no use；I may just as well give up at once.'
‘Try again，Henry！' Whispered his companion，in an earnest and encouraging tone.
These two little words gave him a fresh impulse，and he bent his mind again to his task.
Gradually he began to find the sentences lingering in his memory；and soon，to his surprise and pleasure，the whole lesson was mastered!
"From that day，" continued Mr.Prentice，"there was no boy in the school who learned more rapidly than Henry.From that day till the present hour he has been a student；and he now urges his son George to ‘try again' as he tried. "
"And was it indeed you，father？" asked his son，eagerly looking up into the face of his kind parent.
"Yes，my child.That dull boy was your own father in his early years."
"Then I will try again." said George，in a decided tone；and，flinging aside his half﹣made kite，he turned and re﹣entered the house，and was soon bending in earnest attention over his lesson.
"Well，what success，George？"asked Mr.Prentice，as the family gathered around the tea﹣table.
"I learned the lesson，father！" replied the boy， "I can say every word of it."
"Did you find it hard work？"
"Not so very hard，after I had once made up my mind that I would learn it.Indeed I never stopped to think，as I usually do，but went right on until I had mastered every sentence."
"May you never forget this lesson，my son！" said Mr.Prentice， "You now get the secret of success.It lies in never stopping to think about a task being difficult or tiresome，but in going steadily on，with a fixed determination to succeed."

Have you ever imagined what life will be like in 2060？An international group of forty scientists have made some surprising predictions.They said that in the next forty years，our lives would change beyond our wildest dreams.
Firstly，humans can grow body parts themselves.Dr.Ellen Heber﹣Katz is one of the forty scientists.He says， "People will think it common that sick organs （器官） can be repaired.It's just like the way we fix a car." Damaged parts will be taken away.Scientists could use human cells （细胞） to grow new organs.New technologies like this will also help people to live longer.Within forty years，most people will be able to live up to one hundred years.
Secondly，the scientists have predicted that a machine will be invented to "read" the minds of animals.In 2060，we will be able to "talk" to animals.Scientists say that humans may first "talk" with mammals （哺乳动物） and then other vertebrates （脊椎动物） such as fish.
Our houses might also change beyond our imagination.Dr.Susan Greenfield predicts that when you enter the living room，sensors （传感器） will know you.They will turn on the lights.If you talk to the lights，they will change to the color of your choice.
But what would be the biggest breakthrough （突破） over the next forty years？A number of scientists believe it would be the discovery of aliens.NASA scientist Chris Mckay says， "We may find aliens in space and talk with them." He believes marks of alien life may even be found here on Earth.
Does life in 2060 sound cool to you？Let's wait and see what will really happen then!

Historically，most cars have run on gasoline（汽油），but that may change in the future：cars can also run on other liquid fuels（液体燃料）and electricity.
Gasoline is from oil.The energy in gasoline comes from hydrocarbons（碳氢化合物）.Gasoline provides great power for cars.However，it causes environmental problems，like air pollution and temperature rise.So gasoline can't be the best fuel.
Another choice is electricity.Electricity cars can be as efficient（效能好的）as cars using gasoline，And they produce less pollution.But electric cars themselves are more expensive.Good news is that the cost has been lower and there are more and more places for the cars to get electricity ever since 2010.
The other choices are other liquid fuels.Many of these can be stored in the same places as gasoline，and used in the same cars.They can also be friendly to the environment.
One way to make such fuels is to get CO 2from the air and put it in water.Through chemical reaction，hydrocarbons can be created.However，these fuels take up more space.
Another way is to make such fuels from plants which take in carbon from the air.These fuels are greener in use.But not all of them can be as efficient as gasoline.
For a fuel to be the best，people have to be able to afford it.Unluckily，almost every green technology is more expensive than that of using gasoline.Governments and car producers are doing everything they car to cut down the costs.In the end，the best fuel will be both affordable for car users and green for our planet.

The Youth Climate Summit（气候峰会） a week﹣long festival of climate action for primary and middle schools in the UK，starts on 9 November.It aims to create a fairer，more environmental world and make promises that will help the planet.Climate change is the long﹣term changes in the world's weather patterns that are mostly caused by human activity. "Unlike world leaders， "say the summit's organizers. "young people are refusing to let it drop off the plan. "
Each day has a topic，which includes food and fashion，looking at how humans harm the environment and how to save the planet.Organizations are leading some on line activities.For example，the Marine Conservation Society is hosting meetings on protecting sea fish.Separately，the environmental organization Greenpeace is running a workshop on how to turn worn﹣out clothing into something new and wearable.
The summit will finish on 13 November，when youth ambassadors（大使）wants schools to stop paper waste.Max，another 16﹣year﹣old ambassador wants schools to organize more trips and activities that get students outside to experience the beauty of nature.As part of the summit，hundreds of schools across the country are signing up to the Let's Go Zero activity，aiming to become carbon﹣zero（零碳的）by 2030.
Carbon﹣zero schools are ones that promise to stop emitting carbon in seven areas，including where they get their food and how they use water and recycle their waste.The activity is run by Ashden，a charity working towards climate solutions.Ashden hopes that schools will be able to help each other by sharing ideas and methods.It is also calling on the Government to back the promise.Head over to transform﹣our﹣world.org where you can find out more.

The first emperor of China，Qin Shihuang，completed a huge number of projects during his rule.Between 221 and 210 B.C.，he started the building of the Great Wall.The emperor also ordered the building of a huge army of life﹣sized terracotta soldiers（士兵）.These，he hoped，would protect his tomb after his death.
Lost in Time
The soldiers in Xi'an's terracotta museum are today light brown，but they weren't always.They began as an army of red，blue，yellow，green，white，and purple.Sadly，most of the colors did not last to the present day.After being exposed（暴露）to air during digging，the coating under the paint began to fall off.The paint disappeared in less time than it takes to boil an egg，taking away with it important pieces of history.
New Technology
Now new technology is starting to show the army's true colors.Archeologists（考古学家）have recently discovered an area with more than a hundred soldiers.Many of these still have their painted features，including black hair，pink faces，and black or brown eyes.Chinese and German researchers have developed a chemical liquid（液体）to help save the soldiers' colors.After finding a soldier or another art piece，archeologists put the liquid on it. They then cover it in plastic.
Back to Life
Archeologists are also finding colors in the dirt around the soldiers.It's important not to do anything with the dirt，so the colors won't be lost. "We are treating the dirt as an art piece， "says Rong Bo，the museum's leading archeologist.The next challenge，says Rong Bo，is to find a way to use the colors onto the army﹣again.Once that happens，artists can bring Emperor Qin's army back to its full，bright colors.
