They're life jacket orange, they’re robots and they're capable of sailing the high seas without human intervention.
On Tuesday the National Oceanic and Atmospheric Administration (NOAA) launched a pair of Saildrones(海洋无人机) in Pacific Northwest waters for the first time. Their summer long sailing journey will stretch from Vancouver Island to California. The Saildrone operators will collect data to help set future fishing seasons. The government wants to see whether seagoing. robots can extend fishery surveys now performed by expensive manned ships.
Nora Cohen from NOAA said,“The 23 foot tong seagoing robots can follow a remotely programmed course for up to a year at a time. And they don't require any fuel. We use wind and solar power to drive the sensors.”He added,“It means that we're able to go to places where we don't really want to send people, and go into weather that we really don't want anyone ever to be in, and be able to send back measurements.”
The primary mission is to investigate the species and number of fish in existence and the places where they are. Larry Hufnagle, scientist of NOAA Fisheries in Seattle, said a traditional big NOAA research ship-based survey costs around $25，000 per day. By comparison, one Saildrone runs $2,500 per day.
“It could be a significant saving,”Hufnagle said. “But like anything else, there is a tradeoff in what you get and what you don't get. On the manned ship, we have limited time. It takes a lot of people. We spend a fair amount of money. But there is one thing the Saildrone can't do that humans can: cast a net to catch and positively identify the fish detected below. The Saildrones are going to give us additional data, not replacement data.”
Nora Cohen said Sail Drone, a venture capital-backed company based in Alameda, California, expects to launch a total of 11 of its seagoing robots to survey different water bodies for NOAA this year. The Bering and Arctic seas, coastal California and Gulf of Mexico will be the locations of additional missions.

We're so attached to plastic, but we're careless consumers. Waste plastic is entering our ecosystems and food chains with untold consequences. Cleaning up our polluted world of plastic may seem a noble, but thankless task. However, some people are seeing economic opportunity in the mission.
Plastic Bank, a social enterprise from Canada, is monetizing plastic recycling while empowering those most affected by the waste. It works to prevent waste plastic from entering oceans by encouraging people in developing countries to collect plastic from their communities in exchange for cash, food, clean water or school tuition for their children. After collection, plastic is weighed, sorted, chipped, melted into balls and sold on as“raw material”to be made into everything from bottles for cleaning products to clothing.
“I saw in large quantities; I saw an opportunity,”CEO David Katz told the audience at the Sustainable Brands Oceans conference in Porto, Portugal on November 14.“We reveal the value in this material,”he added.
Plastic Bank was founded in 2013 and launched on the ground operations in 2014 in Haiti, the poorest country in the Western, Hemisphere, where close to 60% of the population live under the poverty line. As result of poor waste disposal and recycling infrastructure (基础设施)，plastic waste enters rivers or is burned and poses the health threats to the local residents.
The company says i has over 2,000 collectors working in the country, with its full- time collectors on average 63% above the poverty line thanks to the income they make from the project. Through its app based payment system, many collectors now have bank accounts for the first time, and are able to ultimately escape ultra poverty.
“Nothing we're doing is against the laws of physics,”said Katz. “All the technology exists for us to solve and save the world. It's only creative thought.”

4.What maybe the best title for the text?

B.Technology finds its way to kick off poverty
C.David Katz speaks at the conference in Porto
D.Plastic Bank is fighting against plastic waste
Christine Reynolds worked at the public library in Yosemite National Park. When the government issued shutdown orders to slow the spread of the coronavirus(冠状病毒), she loaded the back of her car with donated books and began her own mobile library.“I know this may not be conventional, and yet it has worked and I feel of use,”she said.
Across the United States，volunteers are reporting a jump in little free libraries as readers look to pass the time. Made of wood or brick，and placed in front of parks or in the trunk of a car， the libraries have seen their small spaces filled with books.

The time that some people might fill with online services is not an option for me. I turn to books to fill that gap.” said Connor Timpone, who lives east of Yosemite Valley. “Books have been a bright spot for me.”
“The spaces also have transformed into a new purpose. Readers are leaving can goods and other needed items to assists fellow neighbors. The libraries allow neighbors to help one another without getting physically close,” said Greig Metzger, director of the nonprofit Little Free Library.

I am a senior three student and I’m devoted myself to my lessons every day. I dare not waste single minute because I am afraid he will be left behind by others. With much exams to take, I feel nervous. To make matters worse, I have had difficulty in fall asleep since last week. I can’t concentrate myself to the teacher in class, feeling sleepy but tired. Yesterday my parents tell me to have a walk outdoors. “All work and no play makes Jack a dull boy,” they said to me. So I followed their advices. I felt more relaxing after some rest. I have decided to take more exercise from today on.
