Have you ever imagined the life in space？The following will show you the astronauts' daily life.
• Eating in space
If you go camping for more than a week with some friends，you will make sure you have plenty of foods and keep them properly.At the end of your camping trip，you would deal with your rubbish properly before the ride home.
Astronauts almost do the same thing when they go to space.Preparation changes with the food type.Some foods can be eaten in their natural forms，such as chocolate cakes and fruits.Other foods require adding water，such as cheese.Of course，an oven is provided at the space station to heat the food.But there are no fridges，so space food must be kept properly.
• Sleeping in space
After a long day at work，nothing is better than a good night's sleep!Just like on the earth，in space astronauts go to bed at a certain time，then get up and prepare for work again.When going to sleep，they have to attachthemselves，so they don't float （漂浮） around or hit their bodies against something.They usually use sleeping bags located in small crew cabins （乘员舱）.Each crew cabin is just big enough for one person.Generally，astronauts have an eight﹣hour sleep each day when they finish their task.
• Doing sports in space
Exercise is an important part of every astronaut's daily life to prevent muscle loss （肌肉萎缩）.Usually，astronauts exercise two hours every day.Lifting 200 pounds on the earth may be a lot of work.But lifting that same object in space would be much easier.That means the things for exercise need to be specially designed，so astronauts can receive the exercise needed.
Living in space is not just all work and no play.Astronauts have fun，too.They like to look out the window and play with their food.Fun plays an important role in the quality of their life.

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.

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.

Most children are taught the virtue （美德） of honesty from stories.The well﹣known story of Pinocchio teaches the importance of telling the truth.Every time Pinocchio lies，his nose grows longer and longer.Another story is about the boy who"cried wolf." In the end，he loses all his sheep and the trust of his fellow villagers because he tells lies many times.These types of stories show children that "honesty is the best policy." Still，if thisis the case，then why do so many people lie？The fact is that people lie for many reasons.
One reason people lie is to minimize （减少） a mistake.While it is true that everyone does something wrong from time to time，some people do not have the courage to admit their errors （错误） because they are afraid they will be blamed.For example，students might lie to their teachers about unfinished homework.They might say that they left the work at home when，in fact，they did not do the work at all.These students do not want to get in trouble or seem irresponsible，so they make up an excuse﹣ a lie﹣ to save face.
Another reason for lying has to do with self﹣protection.Parents，particularly those with young children，may teach their children to use this type of"protective" lie in certain circumstances （状况）.What should children do if a stranger calls while the parents are out？Many parents teach their children to explain that their mother and father are too busy to come to the phone at that time.In this situation，protective lying can mean greater safety.
People lie for many reasons，both good and bad.Lying to keep the peace or to stay safe can have positive results.However，lying to stay out of trouble can lead to more trouble in the end.Understanding the motives behind the impulse （冲动） to lie might minimize this habit of lying.

Mostly， inventions happen because someone works to solve a problem． Kids are natural inventors．They often create amazing thing from simple ideas．Here are a few examples that might make you wonder，"Why didn't think of that？"
Popsicles
Popsicles were invented by 11﹣year ﹣old Frank Epperson in 1905． He forgot a drink of juice and left it with a stir（搅拌） stick in it outside on a cold night． The next day it was ice． Because of this he couldn't drink it any more， but he could eat it． It tasted good! These ice sticks became popular among kids at school in summer because they were delicious and helped them stay cool．
More than a hundred years later， popsicles are sill one of the best summer treats!
Crayon Holdans
When 11﹣ year﹣ old Cssidss Coldstein needed crayons for a school project，she had a hard time because，there were so many small or broken ones．She found some small clear plastic tubes（管子）at home．Although the tiny tube were usually filled with water to keep flowers fresh， she found that they fit tightly （紧紧地） around the crayons． She was now able to hold them easily．This is how she invented Caryon Holders．
Wristies
When snow gets in kids' gloves and their hands get wet， they feel uncomfortable.10﹣year﹣old Kathryn Gregoary decided to do something about it．She created the wristies as she wanted to keep her wrists（手腕）warm and dry． Wristies are long gloves with no fingers and they are worn under your coat． They help you when you work in the cold because your hands stay warm while you use your fingers． With her parents' help， Kathryn also opened a small shop where she sold her wristie． And she still runsit today．

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.

Can plants talk？Modern research has found something amazing：they do communicate with each other.
It has been known for some time that plants use chemicals to communicate with each other.This happens when a plant gets attacked by insects.The plant gives out chemicals from the leaves that are being eaten.This is like a warning，or a call for help："I'm being attacked!"When another plant gets the chemicals，it starts to give out its own，different chemicals.Some of these chemicals drive insects away.Others attract the wasps （黄蜂；蜜蜂）!The wasps kill the insects that are eating the plants.Scientists hope to learn more about this plant warning system，so that we can use it to grow more crops.
More surprisingly，plants also use sound to communicate.People can't hear these sounds，but plants are making them.Some plants make noises with their roots.Corn and chili plants do this.Some trees make clicking noises when there is not enough water.
Most surprisingly of all，plants have an amazing system of communication that can link nearly every plant in a forest.Scientists call this system the "wood wide web".The wood wide web is linked underground by fungi （霉菌）.It links the roots of different plants to each other.It is in some ways similar to the Internet we use.Using the wood wide web，plants can share information and even food with each other.However，it may lead to bad effects.Plants may use it to steal food from each other，or spread chemicals to attack other plants.Perhaps one day scientists will learn how to create a "firewall" to help prevent these attacks within the wood wide web.
Scientists are learning more every day about the secret ways in which plants talk to each other.Maybe one day we will know enough about plant communication to be able to "talk" with them ourselves.
