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.

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. |
