1 . The world has a plastic problem—and it is increasing.
1. Quit using plastic bags. Instead, take your own reusable shopping bag to the store. People use a trillion plastic bags worldwide every year. About 10 percent are used in the United States alone. That’s almost one bag per American per day.
2. Skip the straw. Today, around 8.3 billion plastic straws pollute the world’s beaches.
3. Don’t use plastic bottles. Buy a reusable bottle and fill it with any type of beverage you like.
4. Avoid plastic packaging. Buy bar soap instead of liquid soap in plastic containers. Don’t buy fruit or vegetables in plastic packaging. In the United Kingdom, leaders are calling for supermarkets to have plastic-free areas. They also want to tax plastic take-out containers.
5. Recycle. We can’t recycle all plastic items, but it is possible to recycle most bottles and milk or juice cartons. Today, Norway recycles 97 percent of its plastic bottle.
| A．Likewise, the average Dane uses four plastic bags per day. |
| B．In contrast, the average Dane used four single-use bags per year. |
| C．So when you order a drink, say no to the straw, or bring your own reusable one. |
| D．However, there are still loads of people ignoring the seriousness of it. |
| E．Scientists are working to find a long-term solution by making plastic more biodegradable (可降解的). |
| F．Some cities, like Bundanoon in Australia and San Francisco in the U.S. have completely or partially banned bottled water. |
| G．How? Machines at most supermarkets take the bottles and give a refund (退款) of up to 2.5 kroner (32 cents) per bottle. |
2 . You’ve heard that plastic is polluting the oceans — between 4.8 and 12.7 million tonnes enter ocean ecosystems every year. But does one plastic straw or cup really make a difference? Artist Benjamin Von Wong wants you to know that it does. He builds massive sculptures out of plastic garbage, forcing viewers to re-examine their relationship to single-use plastic products.
At the beginning of the year, the artist built a piece called “Strawpocalypse,” a pair of 10-foot-tall plastic waves, frozen mid-crash. Made of 168,000 plastic straws collected from several volunteer beach cleanups, the sculpture made its first appearance at the Estella Place shopping center in Ho Chi Minh City, Vietnam.
Just 9% of global plastic waste is recycled. Plastic straws are by no means the biggest source (来源) of plastic pollution, but they’ve recently come under fire because most people don’t need them to drink with and, because of their small size and weight, they cannot be recycled. Every straw that’s part of Von Wong’s artwork likely came from a drink that someone used for only a few minutes. Once the drink is gone, the straw will take centuries to disappear.
In a piece from 2018, Von Wong wanted to illustrate (说明) a specific statistic: Every 60 seconds, a truckload’s worth of plastic enters the ocean. For this work, titled “Truckload of Plastic,” Von Wong and a group of volunteers collected more than 10,000 pieces of plastic, which were then tied together to look like they’d been dumped (倾倒) from a truck all at once.
Von Wong hopes that his work will also help pressure big companies to reduce their plastic footprint.

| A．To show the difficulty of their recycling. |
| B．To explain why they are useful. |
| C．To voice his views on modern art. |
| D．To find a substitute for them. |
| A．Calming. | B．Disturbing. |
| C．Refreshing. | D．Challenging. |
| A．Artists’ Opinions on Plastic Safety |
| B．Media Interest in Contemporary Art |
| C．Responsibility Demanded of Big Companies |
| D．Ocean Plastics Transformed into Sculptures |
3 . A shark moving around the coastline is normally a worrying sight，but this waterborne drone(无人机)threatens floating rubbish instead of people.
Developed by Dutch company RanMarine, the WasteShark takes nature as its inspiration with its whale shark-like mouth. Responsible for collecting waste, the drone will begin operations in Dubai Marina in November after a year of trials with local partner Ecocoast.
According to RanMarine, the WasteShark is available in both autonomous and remote-controlled models. Measuring just over five feet by three-and-a-half feet(1.5 meters by 1.1 meter)，it can carry up to 352 pounds of rubbish(159.6 kg)and has an operational battery life of 16 hours.
By 2016 there were approximately 150 million tons of plastic in the world's oceans. One paper from December 2014 estimated that over a quarter of a million tons of ocean plastic pollution was afloat.
"WasteShark also has the abilities to gather air and water quality data, remove chemicals out of the water such as oil，and heavy metals，and scan the seabed to read its depth and outlines，"said Oliver Cunningham, one of the co-founders of RanMarine. "Fitted with a collision-avoidance system, the drone uses laser imaging detection and ranging technology to detect an object in its path and stop or back up if the object approaches."
"Our drones are designed to move through a water system, whether it's around the perimeter(周边) or through the city itself. The drones are that last line of defense between the city and the open ocean," added Cunningham. "WasteSharks are operating in Dubai, South Africa and the Netherlands and cost $ 17,000 for the remote-controlled model and just under $ 23,000 for the autonomous model."
Dubai-based operator Ecocoast has two WasteShark drones. Co-founder Dana Liparts says they will clean waterfronts for clients including hotels and environmental authorities and that Ecocoast' intention is to have the collected rubbish recycled or upcycled. However, Liparts argues that cleaning waterways doesn't have a one-size-fits-all solution and requires a combination of new technology, preventative measures and changing people's attitudes towards littering.

4 . Scientists believe that one of our most important means of knowing what is going on around us is the sense of sound. We are warned of danger by sounds. Sounds serve to please us in music. Sound has a waste product, too, in the form of noise. Noise has been called unwanted sound. Noise is growing and it may get much worse before it gets any better.
In order to know how noise affects people and animals, scientists have been studying for several years. They are surprised by what they have learned. Peace and quiet are becoming harder to find. Noise pollution is a threat that should be looked at carefully.
Sounds is measured in units called decibels (分贝). At a level of 140 decibels people feel pain in their ears.
Trucks , buses , motorcycles, airplanes, boats, factories---all these things make noise. They trouble not only our ears, but minds and bodies as well.
There is a saying that it is so noisy that you can’t hear yourself think. Doctors who study noise believe that we must sometimes hear ourselves think. If we don’t, we may have headaches, other aches and pains, or even worse mental problems.
Noise adds more tension (紧张) to a society that has already faced enough stress.
