Think about what you like to wear on the weekend.There's a good chance that you like to put on a pair of blue jeans.At any moment，about half of the world's population is wearing jeans.But according to a new study，our love for jeans may be bad for Earth.Denim （牛仔布）might be putting some sea animals in danger.
Every time we wash our jeans，tiny bits of denim will flow out of our washing machines，down into the world's rivers，lakes and oceans.
You might wonder：Isn't denim made of cotton，a natural material？How can it become a danger to nature？Well，in the process of making jeans，denim is treated with many types of man﹣made chemicals.Some improve its durability （耐用性）and feel；others give jeans their blue color.
Scientists studied the Great Lakes in America and the Arctic Ocean in northern Canada.They found denim waste in all of the samples （样本）they had collected.It is feared that the harmful chemicals in denim have spread far and wide.Scientists aren't yet sure how these chemicals might harm animals.
In the study，the scientists also washed jeans to see how many bits of denim each pair would drop per wash.The answer was frightening：About 50，000.Not all of them make their way into the environment.Wastewater treatment plants hold back 83 to 99 percent of them.This may sound pretty good.However，one percent of 50，000 bits are still 500 per wash.Now think about the number of jeans around the world and the times each of them gets washed.As a result，a large amount of denim waste still gets into the environment.
Does this mean we shouldn't wear jeans？Probably not" We need to buy fewer jeans and only wash them when we truly need to do it，" says Sam Athey，one of the scientists. " You don't need to wash your jeans after having worn them only a couple of times. "

Time flies． My summer vacation ended in the blink of an eye， but one thing is still on my mind． From July 25 to 27， I worked as a volunteer at the Wolong China Giant Panda Garden in Sichuan． I experienced the life of being a panda keeper．
My work included cleaning the pandas' home， feeding the pandas and making food for them． The panda I took care of was named Jingke． When I went to feed him， he would stretch（伸出） one of his forefeet out on a shelf that hung on the fence and wait for his food． He would quickly grab the food as soon as I brought it to him． Can you guess what would happened next？ Jingke would lie down and begin to eat． I could hear him crunching（嘎吱作响地咀嚼） on his food and see him twisting his body around like a dancer． It was really cute． This was one of the most interesting things I saw when I worked there．
When I fed Jingke， I touched his fur（毛）． Most people think that panda's fur would be soft． But actually， panda's fur is very hard． I felt like I was touching needles．I looked at his teeth， too﹣ they were sharp and big． No wonder the panda keepers told us that pandas are not only cute， but also dangerous．
I am happy to be so close to the pandas． This experience lets me know that it is no easy to be a panda keeper．

Think of somebody you really admire.You will probably find that their success didn't come easily.As "Father of Hybrid Rice（杂交水稻）"，Yuan Longping got over great difficulties and spent his whole life working to reduce world hunger and helping to feed the country with the largest population.
Wu Mengchao，the "Father of Chinese Hepatobiliary Surgery（肝胆外科）"，focused on saving people's lives for nearly eighty years.He performed more than 16，000 operations during his life.Holding the surgeon' s knife for such a long time deformed his fingers .Wu once said， "It would my greatest happiness if I could work at the operating table until my dying day."
In1969，in order to solve the problem of treating malaria（疟疾），Tu Youyou，pharmacologist （药学家） took on the job as head of a research team.She and her teammates performed different kinds of experiments.However，the results were disappointing.Instead of giving up，they kept trying.Finally，in1972，they made it!In2015，at the age of 85，she received Nobel Prize.
Thomas Edison，the inventor of the light bulb believed that every failure was a step towards success.He once said， "If I find 10，000 ways something won't work，I haven't failed.I am not discouraged，because every wrong try is another step forward.
Sometimes，their success was a surprise，even to themselves.The famous scientist Alexander Fleming said， "When I woke up just after daybreak on 28th September，1928，I certainly didn't plan to revolutionize（变革） all medicine by discovering the world's' first antibiotic（抗生素）.But I guess that was exactly what I did.
Some people only became successful after their deaths.Not like Pablo Picasso who became famous and very rich during his lifetime，the artist Vincent Van Gogh only sold one painting all through his life and that was to a friend.But he kept painting and he painted more than 2，000 artworks in the following ten years.Now his paintings are very popular and they sell for millions of pounds.

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.

Last summer holiday，Aunt Emily took us to a safari park （野生动物园），not far from Liverpool.
I was very happy to go as I had never been to a safari park before.It' s a very interesting park，full of wild animals running freely.
When we got there，we bought our tickets and drove into the park.We were very excited at the thought of going to see the lions.But to get to the lion' s place we had to go through the monkeys' land first.And that was an experience because they climbed all over the car，ate apples and bananas，and threw all kinds of things at us.They seemed very unfriendly.
Anyway，we went on our way to the lions' place where we had to lock ourselves in the car as we knew lions could be dangerous.A lion came up very close to us.The next thing we knew，it was on the bonnet （车盖）.It looked calm but we felt terrified.Aunt Emily，who isn't very brave，started to call for help.The kids started crying.Only my brother，George，stayed cool.I sounded the horn （喇叭） but nobody heard us.
In the end a guard arrived in his car，and the lion just got off our car and started smelling the guard's hand as if nothing was the matter.

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.

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.

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．
