It is a convenient, clear water bottle that can either be drunken or eaten. To drink it, you can either peel off the membrane(薄膜) or tear a hole in the membrane with your teeth to pour the water into your mouth. To eat it, you simply put the whole bottle in your mouth. One problem the scientists have run into is how to ship large amounts of Ooho bubbles(水泡) without arriving with a very wet truck. However, they have attempted to package units of individual bubbles together inside a larger and thicker membrane. It is targeting large outdoor events, such as marathons, music festivals, and sporting events, where tons of plastic bottles are used, and frequently left behind as litter. And too much plastic is sure to do harm to the environment, which could account for their purpose of such a new invention.

The team has been working for the past two years to develop the technology and materials needed to produce Ooho; they have recently applied a patent for their new advancements. The price for an individual bubble or a unit of bubbles has not been set yet, but they cost about two cents to create a unit, which is cheaper than plastic bottles. It has appeared at events in London, San Francisco, Boston, at conferences, festivals, and so on.

Ooho is catching many people’s attention and has raised over $ 1 million and gained 1,000 investors in only three days. It is mostly being sold at events at the moment to keep the consumer’s interest while the production machine is getting up and running. It is quickly making a rise,so keep an eye out this year for these bottles of the future.

【题目】 "When I was 16 years old, I was diving in Greece, but I was disappointed because I saw more plastic bags than fish.” These are the words of Boyan Slat, an engineer who designed the world's first ocean plastic cleanup system.

Every year, more than 8 million tons of plastics end up in our oceans, according to the UN Environment Programme. It is predicted that the weight of ocean plastics will match the weight of all the fish in our oceans by 2050. To prevent this from happening, in 2013 Slat created the Ocean Cleanup, an environmental nongovernmental organization, and put his plan for an ocean cleanup device into action.

After years of research and development in the Netherlands, a device called System 001/B successfully started gathering plastics on October 2, 2019. The device uses a 600-meter-long C-shaped tube to gather all the floating rubbish. Unlike other cleanup methods, the system floats freely according to the direction of the waves, which allows waste to flow into and stay within the device. A sea anchor is attached to either end. This slows down the system as it floats through the water and allows the faster-moving rubbish, carried by the waves, to flow into its mouth. System 001/B can also collect waste below the surface using a 3-meter-deep skirt（挡板）attached to the end. After being gathered, the trash will be dragged back to shore by boat and recycled.

Right now, the system operates in the Great Pacific Garbage Patch, an area that is 3 times the size of France. Once operational, the Ocean Cleanup expects a full fleet to be able to clear 50% of the Great Pacific Garbage Patch in 5 years.

"It remains to be seen whether this dream will become a reality, but it is undeniable that humanity must work together to reduce our plastic use and repair the damage our waste has caused," Slat said. "We are starting to see a young generation that gets it and is excited about a sustainable （可持续的）future, but the question still comes down to: Are we going fast enough, and how much damage will have been done before we get there?"

【1】The underlined word “match” in Paragraph 2 probably means “_________”.

A.compareB.equal

C.measureD.cover

【2】Why did Boyan Slat create the Ocean Cleanup?

A.To collect ocean plastic waste.

B.To help to invent System 001/B.

C.To protect the living environment of fish.

D.To do research on the ocean environment.

【3】What can we know about System 001/B?

A.It can collect and recycle garbage at the same time.

B.It can only gather ocean waste which floats on the water.

C.It aims to clear up the Great Pacific Garbage Patch in five years.

D.It is an ocean-cleaning device which has already been put to use.

【4】What does Slat want to tell us according to the last paragraph?

A.Young generations care less about the environment.

B.The future ecology of the oceans is deeply worrying.

C.People should work hard to decrease plastic pollution.

D.It's quite difficult to repair the damage to the environment.
