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.

Gu Fangzhou，a famous medical scientist，was born in June，1926.Gu's family faced a difficult time with the sudden death of his father.He studied hard and finally entered Peking University as a medical student in 1944.After graduation，Gu made the decision to work to help improve public health.
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.
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.

The Arctic is home to over 21，000 kinds of animals and plants.Two thirds of it is the Arctic Ocean.In winter，it is completely covered with sea ice.In summer，nearly 50 percent of the sea is ice.
It's also home to about 4 million people，a group of whom are Inuit.Jim is an Inuit boy.At 6：30 am，he wakes up and gets ready to go to school in his fur coat.It keeps him warm in the freezing weather.Half an hour later，he gets to school on a ski or snowmobile.Some of his friends go by car instead.At 11 ：30 am，it's time for lunch.There's fish and other meat in his lunchbox.He sometimes eats them uncooked.These foods give him enough energy.Besides local food，some people eat Western food.At 5：00 pm，the snow outside makes everything bright，so he wears snow goggles on his way back home，or his eyes may be hurt badly by the strong light.From December to March，the sun never rises.However，it always shines in the sky during the summer.At 10：00 pm，he goes to bed.Sometimes he stays in an ice house called igloo.I looks cold but it's warm inside.Many local people live in houses made of wood.
The Inuit mainly make a living by hunting and fishing.Now，their life is greatly influenced by climate（气候）change.For example，many animals they hunt for food are disappearing.There is less food for the reindeer they keep，too.They face more terrible weather，such as snowstorms.Hunting becomes more dangerous.Hunters may accidentally fall into water if the ice becomes too thin.Actually，the temperature in the Arctic is 18℃ higher than it was 125 years ago.All Arctic ice may disappear during the summer in less than 100 years.

The invention of barcodes（条形码）is based on a very simple idea.We only need to give each product a specific number and print it. （1） We could simply print the number itself.But this can cause problems.For example，an unclearly printed "seven" could look like a "one" to a computer.It's also true for "three" and "eight". （2） We need a better way of printing numbers so that they can be read correctly at high speeds.That's the problem barcodes solve.
Each number in a barcode is shown by seven blocks of the same size. （3） For example，the number "one" is shown in turn by two white stripes（条），two black stripes，two white stripes，and one black stripe.（4）
A barcode includes different parts and each one provides a specific meaning.The first part of a barcode tells you the country where the product was made.For example，690—692 is the barcode for China. （5） .The final part is about the product itself.This is how barcodes work.
A.Then computers can read it directly. B.All information can be shown by barcodes. C.The next part tells you who produced the product. D.And "nine" looks similar to "six" if you turn it upside down. E.Even if you turn it upside down，it isn't similar to any other number. F.These are colored either black or white to show the number zero to nine. |

INTRODUCTION It's hard to believe that I wrote Number the Stars more than twenty years ago.It seems like yesterday that I answered the phone on a snowy January morning and received the news that it had won the 1990 Newbery Medal（美国纽伯瑞儿童文学奖）. I think readers of every age may match themselves with the important persons in the books they love and ask themselves：Would I have done that？What choice would I have made？ And ten﹣the age of Annemarie in Number the Stars﹣is an age when young people are beginning to develop a strong set of personal ethics（道德观；价值观）.They are beginning to realize that the world they live in is not always good and safe. So they follow a story about a ten﹣year﹣old girl who is caught in a dangerous situation，and she must make decisions.Young readers become cheerful when Annemarie takes a deep breath，enters the woods，faces the danger，stands up to the enemy and wins her victory. Today，the book has been published in many countries and translated into many languages.It found its way into the hands and hearts of children who had read about but never experienced war. . . .Books do change lives，I know；and many readers have told me that Number the Stars changed theirs when they were young，that it made them think about both.cruelty（残酷；残忍） and courage.

The Danish friend who first told me the story of her childhood，and who became the Annemarie in my book，is an old woman now.So am I.We both love thinking of the children reading the story today，coming to it for the first time and realizing that once，for a short time and in a small place，a group of prejudice﹣free（不存偏见的）people created a touching story of love.and kindness towards others.

Recently，teenagers face many kinds of problems.Like many of them.I was once troubled with worries and dissatisfaction.Few people could understand my feelings.（1）
"The problem with your generation is that you always expect to be happy，" my mother once said.（2） Shouldn't we try hard to achieve it？
But now I have noticed a change in my thinking.I gradually realize what my mother said was correct.Over these years，many studies have shown that we are crazy about happiness and high personal confidence（3） In fact，we may often be happier when we stop focusing on happiness.
We should also reset our expectations of the future.Don't expect miracles（奇迹），and accept that no matter how hard we try，feelings of failure and unhappiness will appear from time to time.When we feel sad，it's often because we have learned something painful but important.（4） At the same time，we should learn how to deal with them better than trying to make them disappear.
（5） As my mother tried to teach me all those years ago， "Prepare for the worst，hope for the best，and be unsurprised by everything in between."

B.We should keep the stress off ourselves.
