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.

It was a cold，rainy day.My mother and I drove to the mountains.It was dangerous to make the two﹣hour journey along the highway in such weather.I didn't want to take the risk.But my mother advised that we go to see something at the top of the mountain.
After ten minutes' driving，we stopped the car and got out.Walking along a path，we turned at a comer.Gradually，the peace and silence of the place began to fill my mind.From the top of the mountain，I saw several fields full of flowers，shining like a carpet （地毯）before us.It looked as if the sun spilled （播洒）gold down the mountain.
A lot of questions came to my mind.Who created such beauty？Why？How？
As we moved on，we saw a sign that read， "Answers to the Questions I Know You Are Asking. "
The first answer was， "One Woman一Two Hands，Two Feet，and Very Little Brain. " The second was， "One at a Time. " The third， "Started in 1971. "
On our way home，I was so shocked by what we had seen. "She changed the world.One bulb （一株）at a time.She started almost 50 years ago.It was probably just the beginning of an idea，but she kept at it. " I said， "Imagine，if I had a dream and worked at it，just a little bit every day，what might I have achieved？"

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!

What are the cultural differences between China and the West？You might be able to find the answer in Cao Siyu's comics （漫画）.
Cao，32，was born in Beijing，but left home at 20 and has studied and lived in the US，the UK，and France for 12 years.Having seen so many cultures，Cao wanted to use her drawing sills to show the differences she has experienced.So she created the cartoon series Tiny Eyes Comics.
"My experience shows that although travel is much easier and faster today，the distance （距离） between cultures hasn't shortened，" Cao said.She hopes to build bridges and break down misunderstandingsbetween different cultures.One of her cartoons shows water forms in different countries.Three glasses of water are shown.The glass of water from the US has ice；the one from France is full of sparkling water （气泡水）；the one from China is steaming （冒热气的）.
Cao also uses her cartoons to show different ways of thinking and social customs.During the COVID﹣19 pandemic，she used her comics to explain why Chinese people prefer to wear masks while western people don't."Her simple pictures have played a big part in reflecting Chinese culture，" Italian magazine Grazia reported.
Many foreign readers say that Cao's comics help them understand China，while Chinese living abroad have felt that they are seen and understood.
She said that this voice has been the biggest motivation （动力） for her to keep creating.

A small cloud moves slowly through the air in a hospital operating room （手术室）.In the room a patient with cancer（癌症），lies on a table.The cloud is all around the patient，covering her body and filling her lungs（肺）.The cloud is not smoke.It is made of millions of nano﹣robots（纳米机器人）.These tiny robots move from cell （细胞） to cell in the patient's body，killing the cancer.
Fighting cancer with nano﹣robots is only an idea today，but scientists say that it could be possible in the future.Using nano﹣robots for good purposes such as fighting the illness or repairing the environment may be the way to many of today's problems.
However，nano﹣robots could be a dangerous risk as well.Because nano﹣robots are so tiny，they will have to work in large teams of many thousands to many millions.For this reason，nano﹣robots will have to be programmed（被编程）to build themselves.Scientists will not have the ability to build millions of nano﹣robots one by one.
This ability to re﹣produce is making some scientists worried.What will happen if something goes wrong in the programming？Quite a lot of crazy nano﹣robots would be far worse than any illness.Some people think that if they get out of control，nano﹣robots could make the Earth gone.
What should be done？Should we continue researching nano﹣robots or should we search for other methods？This is one of the many difficult decisions that we have to make in the future.

You may study differently from your friends，but your study habits are not wrong!
Kelly and Maria are best friends with a lot in common.They love doing things together，such as going to movies and concerts，shopping，or just sitting at a small cafe.Since they take a lot of the same school subjects，they would love to study together，but they find this impossible.Their working styles are so completely different that they can't be in the same room while they are studying!
Kelly would like to study in a clean，open space，while Maria works best with books，papers and other things around her.Kelly prefers to study in a totally silent room，but Maria loves to play music or even have the TV on.Kelly can sit for hours without moving，and often gets all her homework done in one sitting.Maria，however，is always getting up，and says that she thinks best when she's on the move.
You might be asking yourself：which way of studying gets better results？Many people believe that a silent，tidy setting（环境）is the way to go，▲.Some research has even shown that outside noise and untidiness help some people focus（聚焦）their attention，because it makes them form a "wall" in their mind around what they are doing and improves their focus.
So，if you're a student who chooses to study while sitting at a table in a busy shopping center，don't worry about it.If you work in total silence，that's OK，too.Judging from Kelly 's and Maria's study habits，the best way to study is the way that works for you.In their very different ways，both of them do well in school，and both finish their work within the required time as well.

Most viruses can be found and killed by our immune system as soon as they enter our bodies.However，some viruses，for example，the coronavirus，are sneaky.They are difficult to recognize and find.These viruses can cause deadly diseases，like COVID﹣19.Human﹣to﹣human transmission can easily occur，and pandemic will therefore break out.Vaccination is by now a simple，safe and effective way to protect us from the diseases.
▲Vaccines are something that "looks" exactly the same as the viruses，mainly made from the viruses that are weakened or killed.They will not make us really ill.They only stimulate and activate our immune system to work，telling it something harmful is coming in.The immune system will know what the "viruses" look like，and send B cells（lymphocytes）or antibodies to find and kill them.Meanwhile，B cells will remember them for the next kill.A vaccine may also give us passive immunity by providing B cells taken from an animal or a human to play the same role.
Scientists have developed more than 180 vaccines to fight against COVID49.The technical approaches of these vaccines can be a little different，but their aims are the same.
Take the inactivated vaccine as an example.In an inactivated vaccine，the coronaviruses are already killed or made into the ones unable to produce more new viruses.When the immune system "sees" them，it will try to kill them.The question is：without enough these viruses• how can B cells remember them？That's why we need to take the vaccine more than one time.Though this vaccine is safe，it might not be as effective as it is expected to be.
The live﹣attenuated vaccine is different.In this vaccine，the viruses are weakened，but they are alive.They can produce enough new viruses to train the immune system to kill and remember them，so people only need to take the vaccine once.The live﹣attenuated vaccine is considered the most effective，but there is a worry：what might happen once these viruses wake up？
Therefore，although vaccination is by now one of the best ways to protect us from COVID﹣19，it can be better.
（1）The coronavirus can .
| A． |
not be killed |

| A． |
needs taking more than once |
| B． |
is equally safe |
| C． |
contains viruses that are killed |

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!

Have you ever entered a tropical rainforest（热带雨林）？Rainforests make up only a small part of the Earth's surface，about six percent，but there are more kinds of tees than any other area in the whole world.
Tropical rainforests are in Africa，Asia，Central and South America，Australia，and on the Pacific islands.The largest tropical rainforest is the Amazon（亚马逊）Rainforest in South America，which covers 1.2 billion acres，or almost five million square kilometres.The second largest rainforest is in Western Africa.
Rainforests provide us with many things.In fact，the Amazon Rainforest is the "lungs of our planet" because it produces 20%of the world's oxygen （氧气）.One fifth of the world's fresh water is also found in the Amazon Rainforest.Furthermore，one half of the world's species of animals，plants and insects live in the Earth's rainforests.80% of the food we eat first grew in the rainforest.25%of the drugs we take when we are sick are made of plants that grow only in rainforests.Some of these drugs are even used to fight and cure cancer.
There are four different levels of trees in a rainforest.The forest floor is the lowest layer full of animal life and receives the least amount of light.The under storey is the dark，cool environment under the leaves but over the ground.The canopy layer is the upper parts of most of the trees.The emergent layer contains a small number of very tall trees.
These different parts of a rainforest exist together to create an ecosystem for many animals，plants and human beings.

When most people decide to buy food, they go to a grocery store. Grocery stores sell many different kinds of food in just one store. Some grocery stores also sell household goods such as kitchen paper, cleaning things, and diapers （尿布）. A grocery store is a convenient place to shop for the kitchen and others.
Although it is comfortable and relaxing to shop at a grocery store, some people decide to buy their food from other places like farmers' markets. At a farmers' market, local farmers sell the foods they grow to customers. The foods they sell often include fruits, vegetables, and meats. Most of these foods are freshly harvested（收获）with no man-made additions.
There are several ways in which farmers' markets are less convenient than grocery stores. For example, packed foods usually are not sold at farmers' markets. Besides, many farmers do not accept credit（信用）cards or checks （支票）as payment for their goods. What is more, most farmers' markets are only open for business once or twice each week. This makes some people not want to shop at farmers' markets, but others are willing because of the fresh and local food there.
Deciding whether to shop for food at grocery stores or at farmers' markets is a personal choice. This choice reflects a person's values about life and about food. Those who value convenience and（多样）will probably choose to shop at a grocery store. People who value freshness and enjoy supporting local farmers will probably prefer the farmers' markets.
