Boyan Slat, a Dutch inventor is cleaning the world’s most polluted rivers in an effort to save the oceans. He has made it his mission    1    (remove) plastic from the oceans. His organization, The Ocean Cleanup, has successfully started to clean the pollution that has been circling in the Great Pacific Garbage Patch. But millions more tons of plastic enter the oceans every year, almost all of it     2     (flow) from rivers.

Just 10 rivers are responsible for around 90% of all that plastic,     3    a 2017 study from the Helmholtz Centre for Environmental Research. “So     4    we focus on the worst rivers, we believe we can really have the fastest and most cost-effective way to close the tap and prevent more plastic from reaching the oceans in the first place,” Slat said.

The Ocean Cleanup is effectively using floating trash collectors called “Interceptors”. These solar-powered, autonomous systems use the rivers’ currents to guide the trash onto a conveyor belt that carry the waste to     5     (await) bins.

The first interceptor went to work in Jakarta, Indonesia, to pull plastic from a waterway called the Cengkareng drain. A second interceptor began collecting trash flowing down the Klang river in Kuala Lumpur, Malaysia. On the other side of the world,     6    Interceptor has recently started removing river pollution near the mouth of the Rio Ozama in the Dominican Republic.

“    7    the river is polluted, the fish die. Every year there are less fish,” Luis Peguero, a local fisherman, explained. When Peguero is lucky enough to reel in (收线拉起) a catch, it     8    not be safe for his family to eat. “You find stuff in the fish, especially the catfish. Trash, bottle lids, even a shoe. The fish can’t survive this,” said Peguero. To him, the modern trash-collecting catamaran (双体船) is a peculiar but welcome sight.

The Ocean Cleanup is working with the local governments and communities to help retrieve (取回) the plastic the Interceptors collect. “By stopping plastic in rivers, we hope to not only address the big global plastic pollution issue, but also really help make life better for the people    9    live near these problematic rivers,” said Slat.

The Ocean Cleanup’s goal is to tackle the thousand most polluted rivers within 5 years. Soon interceptors     10     (head) to Vietnam, Thailand, Jamaica and Los Angeles County in the United States.

“We are getting out tons of plastic every single day,” Slat said. “We accept that we won’t deliver magic in one go. But we’re doing this, step by step.”

In recent years, climate change has had a great impact on the animals in water or on land. In 2013, a lot of people     1    (shock) by a news photo of a dead polar bear     2    Norway’s Arctic island of Svalbard. Due to the increase in temperature, the polar bear appeared     3    (die) from lack of food.

According to climate     4    (scientist), a key climate process called the “greenhouse effect” has two common meanings: the “natural” greenhouse effect and the “man-made” greenhouse effect. The former refers to the fact     5    heat from the sun enters the atmosphere and warms Earth’s surface. Greenhouse gases in the atmosphere trap some of the heat,     6    (keep) Earth’s climate warm and habitable. However, the latter has become a big problem. When people burn fossil fuels, more heat energy is trapped in the atmosphere and causes Earth’s surface temperature to rise     7    (quick).

The evidence shows that the rise in temperature     8    (lead) to an increase in extreme weather and natural disasters worldwide. It is warned that this warming trend will become     9    (bad) if we do not take appropriate measures.

If you’re one of those people planning to do something helpful in honor of Earth Day, you may be wondering what     1    (exact) you can do. We’ve got 10 great     2    (way) to roll up your sleeves and get to work, whether you have five minutes, five hours     3     want to form habits that will last a lifetime.

Since our cars are some of the     4    (great) sources of pollution in our daily lives, it makes sense to start there. Even if you have     5     short trip to work, driving to and     6     work could still be a major contributor to pollution. For example, a person drives 10 miles each way,     7     means he consumes(消耗)about I gallon of gas for the round trip at least.

But that single gallon of gas sends 20 pounds of carbon dioxide into the air. That’s because 1 gallon of gas     8    (weigh) about 6.3 pounds and that produces 20 pounds of carbon dioxide when     9    (burn).So by not burning that 1 gallon, you’ll keep 20 pounds of green-house gas out of the air.

So how will you get around? Consider     10    (take) the bus or train, working from home for the day, or riding your bike if possible. Then you’ll be getting healthier with the planet.
