4 . My sister Alice and I have been trying to get people to stop dropping cigarette butts (烟头) for seven years. One day, we were walking in our hometown and saw hundreds of cigarette butts on the ground. They made the town look so ugly that we decided to start a group to make people stop dropping butts. We called it “No Butts About It”.
At first, we drew pictures with “The Earth is not your ashtray (烟灰缸)” written on them. We put the pictures around our boomtown--in parks, by beaches, and along roads. We wanted to make people understand that dropping butts hurts the environment. Most smokers don’t think that dropping butts hurts the Earth. But it does, and all rubbish does!
Later, we wrote to companies and asked them for money to help us. We used the money to buy ashtrays to give to smokers. We wanted smokers to carry the ashtrays with them so they didn’t have to drop butts.
At the moment, we are trying to get cigarette companies to put an ashtray in each pack of cigarettes. Some companies want to do it. Many people have started to join our group since it began. Today there are 45 other “No Butts About It” groups in America
Now there are even groups in England, Australia, and India! Many newspapers have written about my sister and me over the last seven years. And we have won many prizes for what we have done. But we are not interested in prizes. We just want to make the Earth a better an cleaner place for animals, plants and people.
One day, it will be.

5 . For some people, walking outdoors is a great way to exercise. What may not be so great is seeing the trash(垃圾) all over the ground. Well, some people are doing something about it. They are plogging!(运动+环保).
“Plogging” began in Sweden. The name combine the Swedish words “plocka” which mean picking up litter and the word “jogging” which means running slowly. A Swedish man named Erik Ahlstrom, started the movement in 2016. He says he became concerned about the amount of the trash and litter he saw each day on his way to work. So, he took matters into his own hands. He began picking up the trash.
Plogging, by that term, may have officially begun in Sweden. But many people who exercise outdoors have been doing this for many years. Take Jeff Horowitz,for example. He is a personal trainer in Washington, D.C. He says that he would often pick up the trash while running outside. He even turned it into a game; he would try to pick up the trash without stopping.
Plogging is not only exercise but also community service. As Julie Lawson explains, it can also build closer social connections in a community. Lawson works at Washington, D.C.’s Office of the Clean City. “When the street look bad and it’s dirty, you’re going to feel bad about the community. So if we’re all doing our part and picking the trash up, it’s very easy to help beautify it and build those social connections.”
Plogging can be fun, too. When Dana Allen goes plogging around Washington D.C., she invites her friends. And they make a day of it. “Sometimes we get groups together on a Saturday or Sunday. We go for a run. We pick up some garbage. Then we’ll actually go for brunch after.” Although Allen enjoys plogging, she says she does not do it all the time. When she is training for a serious marathon race, the trash has to wait.
Cities around the world now hold plogging events. The goal is to spread the idea that littering is not acceptable. We hope one day there will not be a need for plogging.

Earthquake rescue robots have experienced their final tests in Beijing. Their designers say with these robots, rescuers will be able to buy more time to save lives during an earthquake.
This robot looking like a helicopter, is called the detector-bot. It’s about 4 meters long, and it took about 4 years to develop the model. Its main functions are to collect information from the air, and send goods of up to 30 kilos to people trapped by an earthquake.
This robot has a high definition 360-degree panoramic camera. It can work day and night and will also be able to send the latest pictures from the quake area.
Dr. Qi Juntong said, “The most important feature of this robot is that it doesn’t need a distant control. We just set the destination information on it, and then it takes off, and lands by itself. It flies as high as 3,000 meters, and as fast as 100 kilometers per hour.”
This robot has a different function — it can change as the environment changes. Its main job is to search for any signal of life in places where human rescuers are unable to go.
As well as a detector that finds victims and detects poisonous gas, a camera is placed in the 40-centimeter-long robot, which can work in the dark.
Another use for the rescuers is the supply-bot. With its 10-meter-long pipe, people who are trapped in the ruins will be able to get supplies including oxygen and liquids.
Experts have said that the robots will enter production, and serve as part of the national earthquake rescue team as soon as next years.

7 . When Alex Lin was 11 years old, he read an alarming article in the newspaper about e-waste. The article said that people were throwing away their e-waste in places it should never go. This was dangerous, the article said, because e-waste contains poisonous chemicals and metals like lead. These harmful substances (物质) can leak into the environment, getting into crops, animals, water supplies — and people.
Alex showed the article to a few of his classmates. They were worried too. But what could they do about this problem with e-waste? How would they even start? “The first thing we did,” Alex says, “was to learn more about the problem.” Alex and his friends spent several weeks gathering information about the chemicals in e-waste and their effects on humans. They learned how to dispose (处理) of e-waste properly and how it could be recycled. “Then,” he says, “we had to find out what the situation was in our town. So we sent out a survey.”
What they found shocked them: Of the people who answered the survey, only one in eight even knew what e-waste was, let alone how to properly dispose of it. Alex and his friends went into action. They advertised in the local newspaper and distributed notices to students, asking residents to bring their unwanted electronics to the school parking lot. The drive lasted two days, and they collected over 21,000 pounds of e-waste.
The next step was to set up an e-waste drop-off center for the town and to find a responsible company to recycle the waste. That was when Alex and his friends learned another scary fact about e-waste — some irresponsible recycling companies don’t break down the e-waste and dispose of it safely themselves. Instead, they ship it overseas to countries such as China and Nigeria, where local environmental laws are not applied. “We checked carefully online to make sure the company we chose didn’t do this,” Alex says.
Because of the work of people like Alex and his team, more and more people are getting the message about safe disposal of e-waste. As Alex says, “Today’s technology should not become tomorrow’s poisonous trash.”

9 . Would you know what to do during a big earthquake? Scientists have some advice for us.
If the ground begins shaking while you are driving stop your car on the roadside and stay in it. If you are in a tall building, don’t use the lift and never jump out of the windows. When you are in a living room, find a strong table or rush into a smaller room like washroom. Then lie down your body. Take care of your head. When you are in a public place, like supermarket or cinema don’t crowding jam (拥挤), or you may fall over and get hurt. Cross your arms to protect yourself . You can also find a place to hide.
After the main shake quickly run out of the dangerous building for there will be small earthquakes. If you are safe, remember not to engage the phone line, keep it free for rescue (援救) using. Don’t go to the hospital if you are not badly hurt, others will really need help. Take part in the rescue action if you can.

10 . A new study by the Zoological Society of London has found that nearly one in five of the world’s 10,000 species of reptiles (爬行动物) are threatened with extinction. The study, which has been printed in the journal Biological Conservation, was carried out by more than 200 experts who assessed the risk of extinction of 1,500 reptiles selected at random from around the globe.
The primary author of the paper, Monika Bohm, explained to the Zoological Society:” Reptiles are often associated with extreme habitats and tough environmental conditions, so it is easy to assume that they will be fine in our changing world. “However, that’s far from the truth:” Many species are very high specialized in terms of habitat use and the climatic conditions they require for day to day functioning, “Bohm said.” This makes them particularly sensitive to environmental changes. “The paper highlights three critically endangered species in its research, including the jungle runner lizard Ameiva vittata, which has only ever been spotted in the Cochabamba region of the Bolivian jungle—an area under threat from the growth of agriculture and logging. The two most recent searches for the species have been unsuccessful. Meanwhile in Haiti, six of the nine species of Anolis lizard in the country risk extinction due to increasing deforestation (毁林).
Also at risk are freshwater turtles, with 50% of all species at risk of extinction from hunting; turtle parts are in high demand as ingredients in traditional medicine. According to the study 30% of freshwater reptile species are also in danger of completely disappearing.
Reptiles have a long evolutionary history: snakes, lizards, crocodiles and tuataras first appeared on earth around 300 million years ago. They are an important part of many ecosystems. ”This is a very important step towards assessing the conservation status of reptiles globally, “Philip Bowles from the IUCN Species Survival Commission said in response to the study.” Tackling the identified habitat loss is key conservation priorities in order to transfer declines in these reptiles.”

| A．Environmental changes cause species variation. |
| B．More trees are being cut down in the Bolivian jungle. |
| C．Reptiles can easily adapt to extreme habitats and climate. |
| D．Species extinction results from tough environment conditions. |
| A．Because local people hunt them for fun. | B．Because their parts have medical value. |
| C．Because they struggle to survive in the wild. | D．Because they can be cooking ingredients. |
| A．To reduce habitat destruction. | B．To increase the harvest of forest trees. |
| C．To assess the current conditions of reptiles. | D．To further the study on the evolutionary history. |
