Water is important to all living things but some areas in the world are short of water a lot.So we should try to protect and save water.
A group of students from Zhejiang University have successfully developed an"air hand﹣washing machine".The machine uses an infrared ray induction system （红外线感应系统），which can feel the presenceof our hands.If it feels there are hands，the water with the air will come from the tap.And it has been proven that it is nearly as effective as traditional hand﹣washing.It uses only ten percent of the water that regular hand﹣washing does.The students have even set up a company to introduce the product to the public.
Li Qizhang，a member of the team that developed the machine，told a reporter that a model of their machine had already been placed in a classroom building at the university and it worked very well.
In 2014，a student called Chen Puyang first thought of the idea while he was washing his hands.Washing one's hands uses a lot of water，Chen thought.Would it be possible to replace the water with air？ Others may not give the question a second thought.However，for Chen and Li，who were studying fluid mechanics （流体力学） at the time，this was considered to be an excellent idea.
Soon，Chen，Li and several classmates started on the project.After a year of research，the team cam up with a gravity﹣driven （重力驱动） hand﹣washing machine successfully.

Have you ever bought something and then changed your mind？For Alison Jenson，15，this used to happen several times a week.Alison was a shopaholic.She just couldn't stop shopping and she loved special offers.
Alison's bedroom is full of stuff. "I've been to every shop in Birmingham，I think， "says Alison.She picks up some earrings.The labels are still on them. "These were half price， "she says. "I've never worn them. "Alison's problem wasn't just jewellery.She also bought a lot of clothes，though not many shoes，because they were usually too expensive.She has also bought lots of other small things - like 20 new covers for her phone.She hasn't used any of them.
According to experts，we all feel excited after we buy something new.For shopaholics，it's a little different.Soon after they buy something，they think they've made a mistake and start to feel unhappy.So they buy themselves something else to feel happier.
Psychologists （心理学家）first described the problems of shopaholics in 1915.However，there was very little research on the subject until recently.Now，doctors think thousands of people suffer from the problem，and the situation is getting worse.There are also more teenage shopaholics now，although most young people don't have enough money to go shopping very regularly.
Alison knew she had a problem. "I often bought something every day.Usually it was something small，but I just needed to buy it， "she says. "I spent money that I got for my birthday，and when I was short of cash，I borrowed money from friends or my parents.When I couldn't go shopping，I felt anxious.Then one day，my parents just looked at all the stuff in my room and said，'This is crazy!' I knew theywere right. "I needed some big changes in my life.
Alison now gets help with her problem and feels she has changed.She no longer thinks she's a shopaholic. "When I want to buy something in a shop，I ask myself two questions， "she says. "Do I need it？Can I afford it？The answer to both questions is usually 'no'，so I walk away.It's great!"

Many of us stayed at home in January because of COVID﹣19，but a special mom and her two babies took a trip.They were driven a few miles from a breeding center in northeastern Argentina to a 1.7 million﹣acre nature reserve called Gran Ibera Park.There the three jaguars were released into the wild.
Their release was the first reintroduction of jaguars in that part of Argentina since the species（物种）almost died out there 70 years ago.Scientists hope they can turn things around for this important apex predator，meaning one that is on top of the food chain （链）.Only 200 to 300 jaguars remain in the country.
"That is the highest level of protection that can be given in Argentina，"says Sebastian Di Martino.He's the conservation director for Rewilding Argentina，which is one of the organizations helping to restore jaguar populations.
The jaguars' journey started in 2018 when the park was built in the Ibera Wetlands.Several thousand jaguars once lived there，along with other important species.But the jaguars' fur was valuable，so people hunted them.Then farmers cleared the land they lived on.With the jaguars gone，the ecosystem was out of balance.
"In the absence of this species，ecosystems stop working well and may even collapse，" Di Martino says. "The main prey （猎物） of the jaguar is the capybara and the caiman.They are very abundant because of the absence of the jaguar，which causes imbalances in the ecosystem."
The park was the first step to give jaguars a place to live.Then they needed to breed.A female named Mariua mated with a male jaguar from Brazil.Mariua then gave birth to the two baby jaguars.
It sounds simple，but the reality is more complicated.Di Martino said that jaguars born at breeding centers have to learn how to hunt and must not become used to humans.Otherwise，they will not have success in the wild.
The people who work at the breeding center stay out of sight.They use video cameras to watch the jaguars from several miles away."We provide live prey for them，without them realizing it comes from people，" Di Martino said.
Mariua wears a radio collar so researchers can track her and her babies，Karai and Pord. "So far，so good.She's been hunting capybaras and wild pigs and is raising her babies very well，" Di Martino says.

Resting her phone on a stand and making the light more suitable， 49﹣year﹣old Lyu Min started her livestreaming session﹣her daily job during the COVID﹣19 outbreak．Dressed in a qipao， a traditional Chinese dress， Lyu started the livestreaming session from her workshop at 10 in the morning， sharing the art of making Chinese knots with many handicraft （手工艺） lovers． Lyu， an inheritor （继承人） of the art of making Chinese knots， which is listed as an intangible （非物质） cultural heritage， became a livestreaming host．
"Though the sales of Chinese knots have dropped a lot， I'm still confident that I can get out of the trouble brought by the outbreak． I can make full use of this period to improve my skills and develop this traditional handicraft online，" she said． Lyu is quite new to the world of livestreaming， having bought all the necessary equipment （设备） after following her friends advice． She practises livestreaming every day and records a large number of educational videos． As face﹣to﹣face interaction is still impractical for many， even as the outbreak has been largely brought under control in China， she thinks livestreaming classes can meet more Chinese knot lovers' needs to learn the handicraft．
She has integrated the anti﹣epidemic spirit into her works， expressing the determination （决心） and confidence of the Chinese people to win against the COVID﹣19． "I love Wuhan， where I showed my works in 2019． Chinese knots are popular among many local people， and I made lots of friends there，" Lyu said． She designed a special Chinese knot to express her thanks to the medics who were sent to support Wuhan several months ago．

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.

Marianne Carus，who started Cricket（蟋蟀）magazine in 1973 and served as Editor﹣in﹣Chief（总主编）until 2012，died on March 3 at the age of 92 this year.
Marianne believed that "only the best of the best is good enough for the young. "In Cricket，children would find wonderful stories with beautiful art，and be encouraged by ideas in the humanities and sciences.Marianne looked for stories from around the world to awaken admiration for different peoples and cultures.Most important，Cricket would never talk down to children.
Marianne knew that children were filled with fun，and she wanted Cricket to be，too - "humor from the heart that makes you laugh out loud. "And so she named her literary magazines after a funny group of bugs（虫子），such as Lady bung and Spider.
Over the years，Cricket has been read by millions of children and given many writers and artists their start.Marianne kept a special box of "love letters" to the magazine.She treasured these letters from Cricket readers，including long﹣ago readers.They told her that their interest in reading had begun with Cricket.
▲She considered other names，such as Troubadour or Taliesin，the singers and storytellers of old who traveled from one place to another to share their songs and stories.Then，one night，she was reading Isaac Bashevi Singer's memoir（回忆录）A Day of Pleasure，about his childhood in Warsaw.In it he wrote：There was a stove in Shosha's apartment behind which there lived a cricket.It chirped the nights through all winter long I imagined the cricket was telling a story that would never end. "That's exactly what Marianne wanted her children's magazine to do-to tell stories that would never end!So the name Cricket became her best choice.
Thank you for everything，Marianne.May the stories，and the laughter，never end!

Volunteering your time is a great way to make a difference in your community.And you'll feel good about doing something that helps people or improves the places around you.

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.

Say you're sitting around with some friends playing video games and someone mentions a game that happens to be one of your favorites．"Oh，that game's easy．So not worth the time，"one of your friends says．The others agree．Although you enjoy the game quite a lot，not wanting to argue with them，you go along with the crowd．
You have just experienced what is commonly referred to as peer pressure（同伴压力），also called peer
influence．You will adopt a certain type of behavior，dress，or attitude in order to be accepted as part of a group of your"peers"．As a teen，you are likely to have experienced the effect of peer pressure in a number of different areas．
We are all influenced by our peers at any age．For teens，as school and other activities take you away
from home，you may spend more time with your friends than with your family．As you become more
independent，your peers naturally play a greater role in your life．
According to Dr．Casey from Cornell University，teens are very quick and accurate in making decisions
on their own and in situations where they have time to think．However，when they make decisions in the
heat of the momentor in social situations，their decisions are often influenced by factors like peers．In a
recent study，teen volunteers played a video driving game，either alone or with friends watching．The
researchers discovered that the number of risks teens took more than doubled when their friends were
watching，compared with when they played alone．This shows that teens may find it more difficult to control risky behavior when their friends are around，or in situations where they are extremely angry．
Just as people can influence us to make unwise choices，they can also influence us to make good ones．A teen might join in a volunteer project because his or her friends are doing it，or get good grades because his or her friends think getting good grades is important．In fact，friends often encourage each other to study，or try out for sports．
While we are always influenced by those around us，the decision to act or not is up to us．So when it
comes to decision making，the choice is up to you．

C．Peer pressure does more harm than good to teens．
D．Tees think it challenging to get good grades at school．
