Can a green machine help the world's poorest kids learn better？Nicholas Negroponte thinks so.He and his team of scientists have invented a new type of computer.As a result，many children who live in poverty （贫穷） will have their own laptop computers!
Negroponte works at a university.He started a group called One Laptop Per Child （OLPC）.The people at OLPC don't work for money.They work to help children learn.OLPC makes computers that don't cost a lot.Then they sell the machines to governments of countries that have many people live in poverty.The governments then give the computes to kids for free.
The XO Laptop computers are made for school﹣aged children in developing nations.Many of these children live in faraway areas and go to schools with classrooms.In order to work，the laptops have to be lasting and student﹣friendly.
The machines have many fun characters like a built﹣in video camera，voice recording，and games.The WiFi lets students share information on the Web and read e﹣books.They also can make music and chat with friends.
Another great character is that it can last for a long time.It can be hand charged and also can be recharged by connecting to a solar panel.Because of these characters the XO laptops make learning fun while helping the environment.
The computers have a colorful name﹣"the green machine".Negroponte thinks they could make a difference in the lives of millions of kids.He says， "Every problem you can think of﹣poverty，peace，the environment﹣is solved with education."
OLPC plans to give out over ten million computers in the next few years.Kids in Thailand，Nigeria，Brazil，and Argentina will get most of them.China and Egypt also want to take part in the program.After that，Negroponte hopes to sell computers to other countries with high poverty.

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. "

②To improve denim's durability and feel.
③To make jeans blue.
| A． |
①② |
| B． |
①③ |
| C． |
②③ |
（3）How many bits of denim might get into the environment every year？
| A． |
Five hundred. |
| B． |
Fifty thousand. |
| C． |
Too many to count. |
（4）What should we do according to Sam Athey's words？
| A． |
We are not supposed to wear jeans. |
| B． |
We need to wash our jeans every day. |
| C． |

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.

When I was very young，people in our village lived by planting fruit trees.My grandmother always took me to the orchard（果园） on the hill.At that time，they had to carry water from the river at the foot of the hill to halfway up the hill.Even though we worked so hard，the production level of fruit was still low because it was short of water there.
One day，two young men led a group of workers to our village.They learned about the difficulties we faced，and later，canals and other projects began to be built in my village， "Who are they？" I asked. "They are good men from our government，" my grandma replied.
Shortly afterwards，I moved to another city for my junior high school.The only reason I ever came back to my hometown was my grandmother.
One day，my family and I made time to return.We were surprised because everything had changed.The canal ran past every orchard so villagers didn't have to go up and down the hill anymore.The river was now so clean that fish swam happily in it.When we arrived home，my grandma took out some fresh pears and apples.She told us that after the water conservation project（水利工程） was completed a policy（政策） was made to encourage more people to increase the fruit production with clean water in the river.
Thank those good men who have devoted themselves to the development of our countryside.

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.

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.
