One cannot discuss Chinese music without mentioning the guqin，one of the four arts-along with game of go，calligraphy（书法）and painting.It first appeared over 3，000 years ago and stands for China's solo musical instrument tradition.
At first，the guqin had only five strings（弓玄），meaning the five elements（元素）of metal，wood，water，fire and earth.Later，in Zhou Dynasty，King Wen of Zhou added a sixth string for his son.King Wu of Zhou，added a seventh string to encourage his army to fight with the Shang.
Ambiencewas important in playing the guqin.Usually，it was practiced in a quiet setting and never for public performance.Ancient artists enjoyed performing by a stream in the mountains.The sound of the guqin mixed with the echoes（回音）from the mountains，until the musician felt he was at one with nature.Playing it in snow was also an enjoyable activity for ancient artists，who believed the instrument was the purest of its kind in the world.Also，a night with moonlight was considered wonderful for playing the guqin.Wang Wei（701-761），a highly talented man of the Tang Dynasty，liked playing it in a bamboo forest on nights with moonlight most.
Guqin pieces are usually three to eight minutes long，with the longest being Guangling Verse，which is 22 minutes long.Other famous pieces include Plum Blossoms in Three Movements，Wild Geese Landing on the Sandbank and Eighteen Songs of a Nomad Flute.
Nowadays，there are fewer than one thousand well﹣trained guqin players and perhaps no more than fifty living masters.The original number of several thousand pieces has greatly reduced to only one hundred works by today.The guqin and its music was added to the list of the Intangible Cultural Heritage of Humanity（人类非物质文化遗产）in 2003.

Boyan Slat has been dreaming of cleaning up the world's oceans for a long time.
In 2010，he went on a diving （潜水）vacation in Greece and was shocked."I saw more plastic bags than fish in the water，" he said.
From then on，Slat began to pay more attention to ocean pollution.He decided to give up higher education and set up the Ocean Cleanup，a non﹣government organization.Its purpose is to clean up ocean rubbish.He has set up the world's first ocean cleanup system （ 系统）with his team.
Every year，over 8 million tons of plastic end up in our oceans，and it can take up to 500 years to break down.In 2018，the World Economic Forum predicted that the weight of ocean plastic would match that of all the fish in our oceans by 2050.Sea animals easily get caught in plastic.They can't move.They can even die if they eat it.Smaller plastic pieces can also enter the food chain （链）and end up in our bodies.
Slat's plan was to create an environmentally﹣friendly，large system to clear out plastic rubbish from the ocean.
After seven years of tests，on October 2nd，2019，a machine called System 001/B came out.It successfully caught and collected a large amount of plastic rubbish floating in the ocean.

A small cloud moves slowly through the air in a hospital operating room （手术室）.In the room a patient with cancer（癌症），lies on a table.The cloud is all around the patient，covering her body and filling her lungs（肺）.The cloud is not smoke.It is made of millions of nano﹣robots（纳米机器人）.These tiny robots move from cell （细胞） to cell in the patient's body，killing the cancer.
Fighting cancer with nano﹣robots is only an idea today，but scientists say that it could be possible in the future.Using nano﹣robots for good purposes such as fighting the illness or repairing the environment may be the way to many of today's problems.
However，nano﹣robots could be a dangerous risk as well.Because nano﹣robots are so tiny，they will have to work in large teams of many thousands to many millions.For this reason，nano﹣robots will have to be programmed（被编程）to build themselves.Scientists will not have the ability to build millions of nano﹣robots one by one.
This ability to re﹣produce is making some scientists worried.What will happen if something goes wrong in the programming？Quite a lot of crazy nano﹣robots would be far worse than any illness.Some people think that if they get out of control，nano﹣robots could make the Earth gone.
What should be done？Should we continue researching nano﹣robots or should we search for other methods？This is one of the many difficult decisions that we have to make in the future.

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.

In 1955，polio broke out in Nantong，Jiangsu Province.It paralyzed （使瘫痪） 1，680 people，mostly children aged below seven.It spread to neighboring areas and resulted in 466 deaths.Gu was asked to lead polio research in 1957. "At that time the only way to prevent polio was to invent a vaccine （疫苗），" said Gu.
In 1959 Gu succeeded in developing the first polio live vaccine.Later，he developed the "sugar﹣coated pill" vaccine in the early 1960s.It not only tasted better but was more affordable and easier to keep.To test the vaccine，Gu tried the vaccine in person and later his one﹣month﹣old son was vaccinated.This inspired his team to vaccinate their kids.They became the first group of people in China to try a polio vaccine. "If we don't believe in what we produce，how can others believe in it？" said Gu.

In 1987 a small company named Huawei was started in Shenzhen.After more than 30 years of development，the company has now beaten Apple and become the world's second largest maker of smartphones.It has also become the world's supplier （供应者） of 5 G.In China and even in the world，Huawei is a wonder.Although it started producing mobile phones not many years ago，it has become one of the most famous phone companies.
But recently，Huawei faces some difficulties.The US government made a law to stop its sales in America.American officials said Huawei gave information that it collected to the Chinese government.At the same time，the US government planned to stop selling parts and services to Huawei.They believed that Huawei's business would be hurt this way.
"We have never received such a request from the Chinese government and we have never tried to get into other systems to collect information，" Ren Zhengfei，Huawei's president said. "The law would have little effect on our company.Huawei has enough ability to deal with the problems，" Ren added.
In an interview several years ago，Ren Zhengfei said， "I started Huawei with only £4000 at the beginning，but now it has become a 100 billion company.The experience was not as romantic as you imagine."

Everything is made of something.Nothing is made of nothing.
Chemistry is about the smallest things that other bigger things are made of，and what happens when theychange.The word chemistry comes from chemical，which is an example of one type of the very small things that other bigger things are made of.The words you are reading now are made of a dark liquid called ink （墨水），which is written on paper.The paper itself is made out of the chemicals that wood is made out of.Both the ink and the paper were made by different chemical processes.A chemical process is what happens when chemicals come together to make other chemicals，and therefore other things.
Cooking makes chemical changes.Your different ingredients are made of different chemicals，and when you put them together and make them hot and cook them，the chemicals change into new chemicals and the different ingredients make something new.That tomato sauce you're making is made of tomatoes，onions，garlic，salt and pepper.Those ingredients each have their own chemicals and their own flavors，but now with your sauce you've made something different，something that has its own flavor，all the ingredients mixed together，all the chemicals mixed together，something new.
You can smell the chemical changes，too，as they go up into your nose，especially when you forget about your sauce and it doesn't just cook but bums and becomes black and has a really bad flavor.You can't make it better，either，because once chemicals change，they can't be changed back again.

Which country grows the most tea？The answer is India.It grows three times as much as China.Which country drinks the most tea？It's neither China nor Japan.It's Great Britain.
In the wild，tea plants may be 9 meters tall.But a plant grown for market is pruned.Pruning keeps the plant only 0.9 or 1.2 meters tall.This is an easy height for tea picking.Only the two top leaves and bud（芽）of each new shoot are picked.So to make money，tea plantations （种植园） must be huge.
In general，there are two kinds of tea：black tea and green tea.Black tea is fermented （发酵）.In the process，the tea loses nearly all of its healthy parts.Green tea is steamed （蒸） right after the leaves are picked.Green tea keeps its healthy parts.For example，it may prevent heart illness.
How did we get tea bags？The answer：by accident.Tea businessmen used to send samples（样品）in tin（锡）boxes.This was very expensive.One businessman thought of a cheaper way.He sent samples in small silk bags.Customers would open the bag.They would make tea as usual.One customer put the bag into a pot.Then he just poured hot water over it.And the tea bag was born.
Shen Nong was the first to drink tea.He was a Chinese emperor.This was about 2737 B.C.Shen drank several cups of hot water daily.One day something happened.Leaves from a wild tea tree fell into the hot water pot.The next cup was poured.The water was now colored.Shen tasted it.He liked it.He drank it all.Shen was proud of his new drink.He served it to his guests.Word spread.People thought this way：tea is good enough for the Emperor，so it must be good enough for the people.Tea became the drink of China.

Pangolins have small heads and long，broad tails.They are toothless.They have small ears，but their hearing is good.Their sense of smell is well﹣developed，too.But their sight is poor.When they feel frightened，they roll up into a ball to protect themselves. "My favorite thing about the pangolin is the scales （鳞片）it has on its body.They look cool， "Landon said.
