There are about 1.5 million kinds of living things on Earth，but how many do you see every day？You often see the big colourful animals，like birds，rabbits，and fish.But look more closely.Can you see the small ones，too？Insects（昆虫）make up 80 percent of all the world's living kinds.Look on the ground.Imagine you could look under the ground，too.Many small living things with one cell live there.Life is everywhere around us，in every cubic foot （a foot＝ 12 inches）.
David Littschwager is a photographer who wanted to find out how many living things lived in one cubic foot .So he made a 12﹣inch cube with a green metal frame.And then he put it in five habitats（栖息地）.He chose a tropical rainforest（Costa Rica），a coral reef（Pacific Ocean），the Table Mountain（South Africa），a freshwater river（USA），and a small park（New York）.Three weeks were spent at each place.He watched，counted，and took photos of everything down to I millimeter in size-that crawled（爬）or flew into the cube.
The results were amazing.Liittschwager found both common and rare living things.He discovered many new living kinds，like a strange transparent octopus that is the size of a fingernail!In total，more than a thousand living things were photographed.Liittchwager said the One Cubic Foot experience was like "finding treasure".David Liittschwager also found that the highest biodiversity（生物多样性）in the reef was in the skeleton coral（珊瑚遗骨）.These skeleton coral are suitable for sea living things of all sizes to grow.Although the coral reef had the widest range of biodiversity，all the other habitats were full of life.Even the city park!

A Story of David Littschwager |
Mobile phones are one of the most useful inventions of the last 50 years， but not everything that is said about them is good． Mobiles are often believed to be the cause of a number of things from poor eyesight and headaches to house fires． There's even one theory that mobile phones should be responsible for the disappearance of bees!
The theory is that the radiation （辐射） given off by mobile phones does great harm to bees， navigation systems （导航系统）． Bees have a built﹣in system a bit like GPS and this helps them find their way back to their hives．But recently， thousands of bees have failed to find their way home． It is believed they are dying far from their hives．
The problem was first noticed by beekeepers in America and is a lot more serious than it at first seems． The important thing about bees is that most of the crops in many countries of the world are pollinated by them． Without bees， the crops can't continue to grow． Many beekeepers in Europe have reported losing between 50 and 70 percent of their bees． Jim Piper， a London beekeeper， said to the reporter， "My business is becoming worse． Twenty nine of my forty hives are now empty．"
Nobody knows for sure whether the theory is true or not， but it's a fact that bees are disappearing in very large numbers． And we can't manage without them．Einstein said that if all our bees disappeared，man would only live for four more years! If the mobile phone theory is correct， we need to do something about it right now﹣before it's too late．

You might not think much about where your garbage goes．But now you might want to know．On July 1，Shanghai introduced a new garbage﹣sorting policy （垃圾分类政策）．People there need to put different kinds of garbage into different bins． Other cities in China will do the same soon．
Garbage sorting is a big problem because there is too much garbage these days．It is bad for our environment．In fact， we can make use of some garbage again． But first， we need to sort it．
For example， if you put an old battery （电池） into the "harmful waste" bin， people can use it to make new batteries． But if you don't， the battery will end up somewhere else．Then， it will pollute the environment．
Garbage sorting and recycling around the world
Germany： There are big machines in supermarkets． You can put bottles in the machines and get money back．

Wild beavers （河狸） are back! Experts say that the wild beaver families are doing well． The beavers are even boosting wildlife and the environment!
Over ten years ago， a family of beavers turned up in a part of the river Otter， in Devon．No one knew exactly where they came from． It was a big surprise一wild beavers hadn't lived in England for around 400 years!
In 2015， the government allowed the beavers to stay there as part of a trial （试验）． They wanted to see if these animals could be reintroduced to the wild．The trial ends in February．Some scientists from the University of Exeter already say the beavers help the wildlife in the area． One scientist called it" an amazing story"．

Beavers aren't the only animals that are being reintroduced to the wild! In 2019， red squirrels were brought back to an area of the Scottish Highlands． Further away， the world's rarest （罕见的）duck， the Madagascar pochard， is making a comeback． It was set free into the wild on the African island in 2019 and is doing well．

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!

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.
Slat and his team are working to improve System 001/B.Their dream is to clear out 90 percent of all the ocean plastic by 2040.

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．
