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.

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.

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.

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. "It was something that shaped my idea of how people should be treated， "wrote a young woman recently，telling me.about her own fourth﹣grade experience with the book. 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.
