1 . 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.

2 . Dutch designer Daan Roosegaarde has spent much of his time seeking artistic solutions to our environmental problems.His past projects include a "Smog Free Tower" to clean polluted air and "Gates of Light", which uses the headlamps of passing cars to light up the 60 floodgates of the Afsluitdijk, a major dam in the Netherlands.Now, he is hoping to use his skills to solve a pressing global problem — space junk!
Scientists estimate that there are over 500,000 pieces of space junk.To deal with the problem, Roosegaarde intends to achieve his goal by educating the public about the urgency of the situation and coming up with possible solutions.The project called the Space Waste Lab started in October 2018 with a laser(激光) show in the Netherlands.The unique outdoor artwork of LEDs used real-time tracking information to point at pieces of space junk floating at altitudes of 200 to 20,000 kilometers.The experience was designed to make the public know more about how much space junk there is.
To find a solution, the designer has been thinking with experts.One of the projects being considered is "Shooting Stars", which attempts to reintroduce the trash to the atmosphere in a controlled way.Upon reentry, the waste would burn in the atmosphere like a shooting star.Roosegaarde envisages that if successful, burning space trash could someday replace fireworks at large public events!
In September 2018, the RemoveDEBRIS satellite successfully sent a net to catch a target while orbiting at an altitude of about 300 kilometers.Sometime this year, the spacecraft will send a harpoon that has been designed to remove space trash.At the end of its task, RemoveDEBRIS will release a sail to bring the satellite itself and hopefully some trash back into the atmosphere where it will burn up.

3 . Like colorful corals, they rocked gently in the ocean current. Only these were not beautiful natural reefs grown over centuries. They were plastic bags, stuck to the Aegean Sea floor since a waste site slid into the water eight years ago.
A team of divers and environmentalists pulled thousands of plastic bags from the water near Greece’s Andros Island this month. The workers described what they found as a “gulf full of plastic corals”.
Seas polluted with plastic have become one of the most shocking signs of human damage to the planet. “It was a very scary thing to see, ”said Arabella Ross, a volunteer diver with Aegean Rebreath. The group carries out underwater and coastal clean-ups. “It really shook me and I think it really shook everyone who saw it, ”she added.
The Mediterranean is among the seas with the highest levels of plastic pollution in the world, the World Wildlife Fund (WWF) said in a report in June. Greece produces about 700, 000 tons of plastic waste a year, or about 68 kilos per person. About 11, 500 tons enter its seas every year. Almost 70% of that returns to the Greek coast, one of the longest in the world. The sea pollution off Andros is thought to date back to 2011, when heavy rain caused a waste site to collapse. Most of the waste fell into the sea.
Aegean Rebreath divers removed blue, black and yellow plastic bags caught between reefs and among fish. It was “like the paradise of the Caribbean Sea, where you find coral reefs everywhere of every color. It was the exact same thing, but instead of corals it was bags, ”diver Arabella Ross said.
The team managed to remove only a small part of the plastic waste they found. They also pulled up 300 kilograms of old fishing traps—known as “ghost nets”—from Andros. In a separate operation in June off Salamina, a small island near Athens, they removed two tons.
“If people are wondering where their rubbish ends up, we see it each time we go into the water,” Ross said.

5 . Vitamin B could help lessen the effects of the most dangerous type of air pollution，according to a new study published recently. In the first study of its kind，a team of international researchers looked at the damage caused by one of the pollutants that has the most severe impact on health: PM2.5.
Particulate matter，or PM，is a type of air pollutant consisting of small particles of different sizes. PM2.5 has a diameter of fewer than 2.5 micrometers，about 30 times smaller than a human hair. These particles are so small that they can go into our respiratory system (呼吸系统), resulting in lung and systemic inflammation (炎症) and stress.
The team found that something as simple as a daily vitamin B supplement could potentially reduce the impact of the tiny particles on the human body，although they stressed that the research was in its early stages and the sample size was small.
For this study，10 volunteers were initially exposed to clean air and given a placebo (安慰剂) to check their responses. The group then took another placebo for four weeks before being exposed to heavily polluted air from downtown Toronto，where an estimated 1，000 cars pass every hour. The bad air was delivered to the volunteers through an “oxygen－type” face mask. The experiment was then repeated，with each volunteer taking a vitamin B supplement daily made up of 2.5 mg of folic acid，50 mg of vitamin B6，and 1 mg of vitamin B12. B6 can be found in liver，chicken and nuts，and B12 in fish，meat，eggs，milk and some cereals.
The researchers found that four weeks of vitamin B supplements reduced the damage of PM2.5 exposure by 28%－76%. The results highlight how prevention at an individual level could be used to fight the harmful effects of PM2.5.

6 . If plastic had been invented when the Pilgrims sailed from Plymouth, England, to North America - and their Mayflower had been stocked with bottled water and plastic-wrapped snacks, their plastic waste would likely still be around four centuries later. Atlantic waves and sunlight would have worn all that plastic into tiny bits. And those bits might still be floating around the world’s oceans today, waiting to be eaten by some fish or oyster, and finally perhaps by one of us.
Because plastic wasn’t invented until the late 19th century, and its production only really took off around 1950, we have a mere 9. 2 billion tons of the stuff to deal with. Of that, more than 6. 9 billion tons have become waste. And of that waste, a surprising 6. 3 billion tons never made it to a recycling bin - the figure that shocked the scientists who published the numbers in 2017.
No one knows how much unrecycled plastic waste ends up in the ocean, the earth’s last sink. In 2015, Jenna Jambeck, a University of Georgia engineering professor, caught everyone’s attention with a rough estimate: between 5. 3 million and 14 million tons of plastic waste each year just come from coastal regions.
Meanwhile, ocean plastic is estimated to kill millions of marine( 海 洋 的 )animals every year. Nearly 700 species, including endangered ones, are known to have been affected by it. Some are harmed visibly, stuck by abandoned things made of plastic. Many more are probably harmed invisibly. Marine species of all sizes, from zooplankton to whales, now eat microplastics, the bits smaller than one-fifth of an inch across.
“This isn’t a problem where we don’t know what the solution is,” says Ted Siegler, a Vermont resource economist who has spent more than 25 years working with developing nations on garbage. “We know how to pick up garbage. Anyone can do it. We know how to deal with it. We know how to recycle.” It’s a matter of building the necessary institutions and systems, he says, ideally before the ocean turns into a thin soup of plastic.

Environmental problems are becoming more and more serious all over the world. For example, cars have made the air unhealthy for people to breathe and poisonous gas is given off by factories. Trees on the hills have been cut down and waste water is being poured continuously into rivers. Furthermore, wherever we go today, we can find rubbish carelessly disposed(处理)．
There are different kinds of pollutants, each of which comes from different sources. It is necessary to identify the source of pollution, in order to make a policy to get rid of them. Different products, processes and activities of our industrialized world together form the major source of pollution.
The forms of pollution can be mainly divided into three kinds—solids，liquid and gas. These pollutants have greatly damaged our planet and continue to do so. In fact，pollution is threatening our existence. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even posed a great threat to man’s existence.
We must face the situation that exists and take action to solve our environmental problems. For instance, new laws must be passed to place strict control over industrial pollution; the public must receive the education about the danger of pollution and raise their awareness of protecting the environment and so on.
The earth is our home and we have the duty to take care of it for ourselves and our later generations. Fortunately, more and more people have realized these problems. Measures have been taken to deal with these situations by the government. And laws have been passed to stop pollution, I hope the problems will be solved in the near future and our home will become better and better.

8 . Oil is essential for modern life. About 64 percent of the world’s oil is located in the Middle East, but the heaviest consumers of oil are Europe, America, and Japan. The problem lies in getting the oil from the countries that produce it to the countries that consume it. This is mainly done using oil tankers. Usually the oil is shipped safely and with no problems, but occasionally there is a disaster.
Every year millions of tons of oil are spilled into the ocean. Although this is only a small percentage of the total amount shipped around the world each year, this spilled oil can have terrible effects on ocean life, including the coastlines where the oil washes up onto shore.
One of the worst oil spills in history occurred along the Alaskan coastline in 1989, when the Exxon Valdez tanker got stuck off the coast of Alaska, spilling 42 million liters of oil. Although it wasn’t the largest oil spill, the disaster was terrible because it occurred in such a sensitive natural area. In this spill, the tanker’s captain, who was tired from overwork and drinking alcohol, had gone to take a rest. He gave control of the ship to another sailor, who was unfamiliar with the route. The ship ran onto Bligh Reef. Damaged by the reef, the ship leaked oil out into the ocean. More than 1,600 kilometers of coastline were affected by the oil spill. Many birds and otters died as a result of the oil covering their skin, and many other sea creatures and the animals that fed on them were also severely affected.
1. Which country is NOT among the largest consumers of oil?| A．Japan | B．Iraq |
| C．America | D．Germany |
| A．The birds. | B．The otters. |
| C．The sea creatures. | D．The birds and the otters. |
| A．The oil leak of Alaska is because the captain was unfamiliar with the route. |
| B．Many birds and otters died from eating the spilled oil. |
| C．Alaska spill was the most serious spill of all time. |
| D．Although some oil leak is not serious, it will affect ocean life. |
9 . Clean water is not only important for food production, but necessary for our life. However, large numbers of people in Asia and Sub-Saharan Africa are going without. The World Health Organization reports that almost 4,000 children die each day for dirty water or lack of water.
Agriculture is the primary user of water at 70-85% of fresh water in the world. Industrial uses of water don’t often come to mind, but you may be surprised to know that industry uses 59% of the water supply in developed countries.
Home use takes up only 8% in the world. But as cities grow, the local government has to cut down on water use. Many cities are turning to privatization (私有化) of water as a method of controlling use. The poor are paying as much as a quarter of their monthly income for water in some developing countries.
In 60% of large European cities, groundwater is being used at a faster rate. People are saving water by simply using less and being careful with what they do use. Sometimes it’s as simple as not throwing out water that they could use elsewhere.
In Australia overuse of water has always been a problem. The Australian government has encouraged households and industries to collect rainwater and reuse water from showers. Technology is helping householders for shower and bath water for reuse in toilets or gardens.
The U.S. Environmental Protection Agency has made a water saving program designed to encourage families and businesses to examine their water use and save more water. Good water management has been considered by scientists and the UN as the key to solving the water problem. We can all work together to protect our valuable water in our daily life.

10 . Climate change will increase US wildfires,and the smoky air will cause terrible problems in areas far beyond those burned,reports an environmental group Thursday.
Two-thirds of Americans,or nearly 212 million,lived in states suffering from wildfire smoke three years ago,according to the report by the Natural Resources Defense Council(NRDC).These areas,which had smoke for at least a week,were nearly 50 times greater than those burned directly by fire.
“It affects a much wide area of the United States than people have realized.” says author Kim Knowlton,a Columbia University health professor,adding the smoke can move up to hundreds of miles.She says the smoke contains air pollution and can cause several kinds of diseases.
Texas was hit hardest in 2011,when smoke stayed for at least a week in areas that are home to 25 million people,according to NRDC’s report.Illinois,which recorded no wildfires within its borders, came second with nearly 12 million people affected by smoke that moved in from elsewhere.The other eight states with the most people in touch with smoky air were,in descending order: Florida,Missouri,Georgia,Louisiana,Michigan,Alabama,Oklahoma and Iowa.
Nearly two dozen states had no wildfires within their borders in 2011,but eight of them still had at least one week of smoky air: Illinois,Missouri，Iowa,Kansas,Nebraska,Indiana,Wisconsin and Ohio.
Only 18 states and the District of Columbia had no people in touch with at least a week of smoke that year,although five of them—Alaska,California,Hawaii,Nevada and Utah—had a large area burned by wildfires.
The problem will only get worse.Knowlton says.Scientific research shows climate is causing higher temperatures and health problems.
