Sleepwalking（梦游） is when your child gets out of bed and walks around as if he 's awake，but he's actually asleep.Sleepwalking doesn't hurt your child，and it usually disappears when the kid grows up.
Sleepwalking happens during deep sleep.Your child might get out of bed and walk around as if he's awake，but he won't respondnormally to you or anything around him.This may make you upset.But try not to worry﹣your child is OK.
In fact，sleepwalking is quite common.7% to 15% of children sleepwalk，and it doesn't usually mean that there's anything wrong with them.Children aged 4 to 12 are more likely to sleepwalk.Both boys and girls sleepwalk.
Sleepwalking often happens in the first few hours of the night.When it happens，your child 's mind is asleep.However，his body is awake at the same time.
Sleepwalking usually has something to do with age and development.However，some things can increase your child's sleepwalking.For example：
●Bad habits that cause poor sleep
●Fever or some other illnesses
●A family history of sleepwalking
●Medical conditions that cause poor sleep
If your child is sleepwalking at least once every night，it's best to see a doctor.Also see a doctor if your child's sleepwalking is influencing the sleep of other family members，or if you're worried your child might hurt himself while sleepwalking.

Vicuna，a small town in the north of Chile，is a great place for watching stars all year round.Although it is near the sea，the cold，wet air from the coast does not bring clouds.Instead，dry winds from the desert keep the clouds away at night.In fact，the sky is so clear in Vicuna that it is possible to see many stars that can be seen only with advanced（先进的）instruments in other parts of the world.
In Vicuna，distant（遥远的）star systems such as Magellanic Clouds can be seen without the help of an instrument.That is why the town was chosen as the home of a number of sky observatories（天文台）.One of them，the Mamalluca，is quite different from the typical observatories used by scientists.This observatory was built for tourists who like to look at the stars.During the year，Vicuna's hotels accommodatethousands of tourists who come from all over the world to see the night sky as they have only seen it in books.The cloudless sky is clearly a moneymaker for the town，which plans to set up even more observatories.It was recently decided that building observatories would go on for another few years.
At one point，however，the town faced a serious problem.As the town grew，more streetlights were added，making it more and more difficult to see the stars at night.The town saved the night sky by building a new system of lights that lit up the streets without influencing the view of the sky.

As Internet users become more dependent on the Internet to store information，do people remember less？if you know your computer will store information，why do you store it in your own personal memory，your brain？Experts are wondering if the Internet is changing what we remember and how.
In a recent study，Professor Betsy Sparrow made some experiments（实验）.She and her research team wanted to know how the Internet is changing memory.
In the first experiment，they asked two groups of people to put 40 unimportant facts into a computer.The first group of people understood that the computer would store the information.The second group understood that the computer would not store it.Later，the second group remembered the information better.People in the first group knew they could find the information again，so they did not try to remember it.
In the second experiment，the researchers gave people facts to remember，and told them where to find the information on the Internet.The information was in an exact in an exact computer folder（文件夹）.Surprisingly，people later remember where the folder is better than the facts.When people use the Internet，they do not remember the information.However，they remember how to find it.This is called "transitive memory （交互记忆）".
According to Sparrow，we are not becoming people with poor memories as a result of the Internet.Instead，computer users are developing stronger transitive memories；that is，people are learning how to organize a lot of information so that they are able to get it at a later date.This doesn't mean we are becoming either more or less clever，but there is no doubt that the way we use memory is changing.

Eight hundred years ago，a man in southern Turkey invented an amazing clock.It was more than 7 meters high.At is base（基座）was a life﹣size model elephant.Every half hour，something amazing happened.The whole clock came alive Model birds，dragons，and people started to move.
The clock's inventor was an engineer named al﹣Jazari He lived in Turkey.Al﹣Jazari was probably one of the greatest engineers in history.Some historians call him "the father of modern﹣day engineering. "
We know about al﹣Jazari mostly from a book that he wrote._________They include clocks and hand﹣washing machines.The book also has drawings that show how each machine works.
Many everyday things today﹣from toys to car engines（发动机）--still use al﹣Jazari's ideas.Without his machines with moving parts，we might no have modern﹣day robots.
Today，it is still possible to see what al﹣Jazari's elephant cock looked like.A full﹣size working mode is in Dubai's Ibn Battuta Mal.There，every half hour，al﹣Jazari's most amazing invention comes to life once again.
How Does the Elephant Clock Work？
A bowl with a small hole floats（浮）in a water tank（水箱）inside the elephant's body.As the bowl slowly sinks（下沉），it pulls a rope that moves a human figure.His moving pen shows the number of minutes past he hour.
Every half hour，the water bowl becomes full and sinks completely. Thiscauses a ball to fall from the top of the clock.The movement of the ball causes a phoenix to move and make a sound.
The ball then drops out of a falcon's mouth into the mouth of a Chinese dragon.The weight of the ball causes the dragon's head to move down and the dragon's tail pulls the water bowl back up.
Finally，the ball drops out of the dragon's mouth and into a vase.As the ball lands in the vase，the elephant driver moves and makes a sound.The cycle begins again until there are no more ball in the top of the clock.

If your pencil box is broken，the batteries（电池）in your flashlights run out，or you have some leftover food，how will you deal with these things？You will probably throw them all into one rubbish bin.But actually，we need to sort（分类）all the rubbish separately.If you don't sort your rubbish，all of it will go to a special place where it is buried（埋藏）together.As a result，it will take up some fields.Some rubbish will pollute the groundwater.Some rubbish that can be reused will be wasted.
In recent years，some Chinese cities have been working hard on rubbish sorting.
Shanghai has called on all the people living in this city to sort their rubbish into four groups：wet，recyclable，harmful and dry.Wet waste is known as household waste.They are things you don't want but pigs can eat.Paper，metal，glass，plastic and other things that can be reused are recyclable waste.Harmful waste includes thins like medicine，batteries.Finally，any waste that is not wet，recyclable or harmful will go to the "dry waste" bin.
Many other Chinese cities are also using this way to sort their rubbish.For example，Deyang has been sorting its rubbish into the same four groups since several years ago.Students in Deyang have already received waste﹣sorting guidebooks.They have studied these books and known how to sort the rubbish.
China is now improving its waste﹣sorting efforts.There is still a long way to go.But it's never too late to learn how to sort your rubbish rightly.We should take an active part in it.

With her eyes feeling increasingly tired and her vision blurry（视力模糊的），l6﹣year﹣old Tian Ting went to the hospital with her parents in January.She was shocked when she found out that her eyesight dropped from 5.0 to 4.6 in only a term. "A few of my friends have had the same experience lately，" Tian said.
In fact，poor eyesight among Chinese primary and high school students rose from 59.2 percent to 70.6 percent in the first six months of 2020，according to the Ministry of Education.
To protect students' eyesight，the Chinese government has worked out new requirements （要求） for school supplies （供应品） and equipments that will take effect （生效） on March 1，2022.For example，according to the requirements，the size of text in students' textbooks should be no smaller than nine﹣point.Teachers should also try not to use projectors （投影仪） or other multimedia equipments （多媒体设备） that are too bright，Beijing Daily reported.There are also requirements for desks and classroom lights.For example，these lights should give off （散发） as little blue light as possible.
Blue light is bad for our eyes，as it can kill the photoreceptor cells （光感器细胞） we need for vision，according to Harvard Medical School.Many of the electronic devices we use every day，like our phones and computer screens，give off blue light.
Chinese government has also taken other steps to protect students' eyesight in China.In May 2020，the National Health Commission urged schools to make sure that students have at least two hours of outdoor activity a day.

King:I heard a door slam. What's happening? If you made a promise, you must honor it.
Narrator:The princess was angry but obeyed her father. So, the king, the princess, and the frog enjoyed dinner together. It was mutton stew, the cook's specialty.
Frog:I was hungry, but now I'm full. Thank you for dinner. Kindly show me to my bed now.
Narrator:The princess did as she was asked, but the frog looked sad!
Frog:You have welcomed me into your home, but I can tell that you don't want to be my friend.
Narrator:The princess's face went red, for what the frog said was true. She bent down to kiss the frog, but ended up kissing a prince.
Frog:I am a prince who was turned into a frog, and your kiss turned me back. Thank you, dear friend!
Narrator:The prince and princess were wonderful friends from that day on and lived happily ever after.

There are about 1.5 million kinds of living things on Earth，but how many do you see every day？You often see the big colourful animals，like birds，rabbits，and fish.But look more closely.Can you see the small ones，too？Insects（昆虫）make up 80 percent of all the world's living kinds.Look on the ground.Imagine you could look under the ground，too.Many small living things with one cell live there.Life is everywhere around us，in every cubic foot （a foot＝ 12 inches）.
David Littschwager is a photographer who wanted to find out how many living things lived in one cubic foot .So he made a 12﹣inch cube with a green metal frame.And then he put it in five habitats（栖息地）.He chose a tropical rainforest（Costa Rica），a coral reef（Pacific Ocean），the Table Mountain（South Africa），a freshwater river（USA），and a small park（New York）.Three weeks were spent at each place.He watched，counted，and took photos of everything down to I millimeter in size-that crawled（爬）or flew into the cube.
The results were amazing.Liittschwager found both common and rare living things.He discovered many new living kinds，like a strange transparent octopus that is the size of a fingernail!In total，more than a thousand living things were photographed.Liittchwager said the One Cubic Foot experience was like "finding treasure".David Liittschwager also found that the highest biodiversity（生物多样性）in the reef was in the skeleton coral（珊瑚遗骨）.These skeleton coral are suitable for sea living things of all sizes to grow.Although the coral reef had the widest range of biodiversity，all the other habitats were full of life.Even the city park!

"If we don't believe in what we produce，how can others believe in it？" said Gu.
Gradually，the sugar﹣coated polio vaccine was made available in China.It saved millions of people，especially kids，from being disabled.In 2000，the World Health Organization （WHO） announced that China was already a polio﹣free country.
