Engineers have launched a huge garbage collection device to gather plastic material floating in the Pacific Ocean between California and Hawaii.

The plastic makes up what is called the Great Pacific Garbage Patch. It is the world's largest spread of garbage, at twice the size of the state of Texas.

The organization Ocean Cleanup created the collection device, whose founder is Boyan Slat, a 24-year-old inventor from the Netherlands.

Slat was just 16 years old when he was moved to clean up the oceans. Last Saturday, a ship pulling the pipe-shaped floating barrier left San Francisco for the Garbage Patch. The barrier, called the floater, is 600 meters across. Attached to it is a screening skirt that hangs three meters down in the water.

The screen is designed to collect the plastic as it moves through the water. Sea animals can safely swim under the barrier.

The cleanup system also comes with lights powered by the sun, cameras, and other special devices. So the system can communicate its position at all times. That way a support ship can find it every few months to remove the plastic it has collected.

“The free-floating barriers are made to survive extreme weather conditions and damage from continual use. They will stay in the water for twenty years and in that time collect 90 percent of the garbage in the patch,” Slat added.

George Leonard is the chief scientist. He expressed concern about the cleaning project. He said even if plastic garbage can be taken out of the oceans, more continues to enter the water each year. He also raised concern that animals might be captured by the net hung below the surface.

But, Boyan Slat said he did not think that would happen. The system will act as a “big boat that stands still in the water”, with nothing for sea creatures to get caught in.

1. What is the function of the screening skirt in the floater?
A.To gather plastic.B.To catch sea animals.
C.To protect the floater.D.To give the floater power.
2. Where is the Garbage Patch?

文章大意:这是一篇说明文。本文介绍了古巴民间人士为恢复珊瑚礁而采取的修补措施。

【推荐1】A small group of Cuban dive instructors have started a project to grow coral (珊瑚) and replant it. The divers hope to restore part of Cuba’s barrier reef (堡礁). And they are working with limited financial support and using materials recovered from the coast.

Luis is one of the project’s leaders. The 44-year-old fisherman grew up on Cuba’s north coast. He said, “It’s incredible to see the loss of coral in the past 30 years.” He added, “Our dream is to make the parts of the barrier reef that have lost their coral grow again.”

To make that happen, Luis worked with other dive instructors and neighborhood schoolchildren with the support from Cuba’s environmental organizations. They began collecting pieces of coral spread across the ocean floor after large storms three years ago. The pieces were then hung on branches of underwater “trees” made from old plastic pipes and supported by fishing lines recovered from the coast. They were then “replanted” on the coral reef, fixed by nails driven into the rock. In a year, most survive and grow enough to repopulate the part of the barrier reef between 60 to 80 meters in length.

Like many coral reefs around the world, the ones in Cuba are threatened by changing water temperatures, destructive plants and animals, pollution and over-fishing. It is reported that the world has already lost 30 to 50 percent of its coral reefs.

Karine is a French diver who just visited Cuba for the first time. She said the reef looked better than others she had seen on dives elsewhere in the world, including in Africa. “The coral needs to be protected,” she said after two dives on a recent trip to nearby Varadero. She said, “It’s good to see that in Cuba they take care of what they have, and that it is still not too affected by too much tourism.”

1. What can we infer from the recovery of the Cuba’s barrier reef?
A.It is just a new project to start.
B.It is a slow and difficult process.
C.It is mainly carried out by schoolchildren.
D.It is greatly supported by the government.
2. How do the dive instructors fix the pieces of coral on the reef?
A.They are fastened to the rock by fishing lines.
B.They are supported by the trees on the ocean floor.
C.They are placed firmly by nails driven into the rock.
D.They are hung by old plastic pipes collected on the coast.
3. What does the underlined word “destructive” in paragraph 4 mean?
A.Endangered.B.Beneficial.C.Plentiful.D.Harmful.
4. What is Karine’s attitude towards the Cubans’ effort to recover the coral reef?
A.Doubtful.B.Concerned.C.Positive.D.Disappointed.

【推荐2】Recycling



Recyclable items are waste materials that can be processed to make new products. The recycled materials go through an intense process of separating the materials and converting into reusable products. At Waste Control, we offer a suite of on-site and off-site recycling services to meet the needs of our residential and business customers.

ON-SITE RECYCLING SERVICES

At the Waste Control facility, we have Drop-off Recycling and Buy-back Recycling Centers. The drop-off recycling center is a free service and is located next to the Transfer Station Building entrance. The Buy-Back Recycling Center is located on the north end of the facility and is for customers wishing to be reimbursed(报销,偿还) for their recyclable materials at current market rates.

OFF-SITE RECYCLING SERVICES

We also offer many off-site recycling services to meet your needs. We maintain free drop-off recycling sites throughout the community for common recyclable materials and residential waste oil and antifreeze. We also offer off-site residential roadside recycling and business recycling services.

HOURS & DIRECTIONS

Waste Transfer Station, Drop-off Recycling Center, & Buy-back Recycling Center:

7:30 a.m. to 5:30 p.m. – 7 days a week

Business Office:

8:00 a.m. to 5:00 p.m. – Monday through Friday

Holiday Hours:

The Business Office is closed on all major holidays (New Year’s Day, July 4th, Memorial Day, Labor Day, Thanksgiving, and Christmas).

The Transfer Station is open for self-hauled waste, drop-off recycling, and buy-back recycling for limited hours during holidays. The facility is closed Christmas Day, New Year’s Day, and July 4th–if it falls on a weekend. The facility closes at 12 noon on Memorial Day, Labor Day, Thanksgiving, and July 4th–if it falls on a weekday. The facility is open on all other holidays.

Waste collection and roadside recycling services are uninterrupted during holidays, except for Christmas Day and New Years Day. If Christmas Day or New Year’s Day fall on a weekday, there will be no pickup on the holiday and all garbage and recycling services will be moved one day forward from your regularly scheduled pickup for the remainder of the week. For example, if Christmas falls on a Wednesday, customers with regularly scheduled Wednesday service will be picked up on Thursday. Customers with regularly scheduled Thursday service will be picked up on Friday. Customers with regularly scheduled Friday service will be picked up on Saturday.

文章大意:这是一篇说明文。文章主要说明了谷歌利用人工智能软件可以快速定位有害的海星,帮助拯救珊瑚礁。

【推荐3】Artificial intelligence (AI) could help stop one of the biggest dangers to the Great Barrier Reef, amazingly saving huge areas of coral from a harmful starfish. Google has teamed with scientists from the CSIRO to create AI software that could pick out the dangerous starfish, which is one of the natural wonder’s three biggest killers.

The new way, using footage from an underwater camera to recognize starfish outbreaks on the Queensland reef, takes the place of an old method and early results show as well as cutting down man’s work, the new software has the advantage of correctly picking out more of the dangerous life on coral, stopping damaging outbreaks before they occur.

Professor Russ Babcock, an expert with CSIRO, said Google’s AI technology, developed over 18 months, could be trained to find out starfish more easily than the old method developed in the 1970s. “We used to send out divers to count the starfish one by one. Now we just look at the images collected and the program can find 20 at a time,” he said.

Google CEO Sundar Pichai said he was excited about the company’s effort put into the reef project. “We have put a lot of effort into the engineering in Australia and we will continue to do more work around AI there,” he said. “There are other good ideas about the technology and you will see us build on it. Our goal with our AI research teams is to strike partnerships with other groups, like universities and governments, to give its full play.”

Professor Babcock said the AI software, which would be put into use on other reefs worldwide, was not the only solution to the starfish affecting the Great Barrier Reef, but one that could have an wide application.

1. What is the function of Google developing the AI software?
A.To pick out a kind of starfish.B.To kill dangerous fishes.
C.To protect the environment.D.To test a new camera.
2. What advantage does the AI technology have over the old method?
A.It is less likely to break down.B.It can be started more quickly.
C.It costs less for its development.D.It can do the work more easily.
3. What’s Sundar Pichai’s attitude towards the reef project?
A.Doubtful.B.Uncaring.
C.Supportive.D.Disapproving.
4. It can be inferred form the passage that ________?
A.The AI software is the best way to stop starfish outbreak.
B.The AI software can be applied widely.
C.The research teams won’t continue to do more work around the engineering in Australia.
D.The old method used to look at the images collected by an underground camera.
