For years, Mark Hager worked as an at-sea fishery observer, going out on New English fishing boats for days or weeks and keeping detailed records of every fish caught or thrown back. The work could be perilous: on one trip, a boat turned sideways in 20-foot seas, and Hager and the crew put on survival suits in case they had to jump overboard. But the counting was essential to protecting the ecosystem.

In the early 2000s, the fishing industry began fixing video. cameras on boats, so that humans could track the data from ashore. In 2019, Hager and the Gulf of Maine Research Institute launched a company, New England Marine Monitoring, based in. Portland, Maine, to provide technology support for ships using electronic monitoring. His team has to watch hours of video footage (镜头), look for each moment when a fish is discarded (丢弃), and then make a note of the species and the time it was discarded. In ten hours of video, there might be 45 minutes between each case of a discarded fish

When Hager consulted with other scientists, they came up with a new idea. Now Hager and his team are using their notes as training data for an artificial intelligence (AI) algorithm (算法) —programming the AI to scan the video footage and indicate points of interest along the time line for a human to look through. “Instead of ten hours of video, we’ll be able to look at about 100 pictures, which we can do in about 20 minutes.” Hager says.

The result could save time and money, but Hager has a bigger goal. He wants to prove that AI algorithms can be used to count every fish that’s caught and discarded. To be effective, the algorithm will need to be able to identify the total volume of a fish haul (一网鱼的量), count containers of fish, and potentially even count and measure individual fish. Using video monitoring to count a small amount of the total catch is one thing. Using it to count the entire haul on a ship is a huge challenge—one that has never been achieved before.

How would you like it if you are able to go to your local park and pick some tomatoes, potatoes or even bananas for dinner. Sounds too good to be true, right? For residents of Andernach, a German city, it’s not just a Utopian dream — it’s the reality. In 2010, Andernach began its “edible city” project, planting 101 varieties of tomatoes in public green spaces around the city centre. Its 30,000 residents are free to help themselves to whatever grows, as are any other visitors. Every year a new type of plant is introduced. In 2021, 100 types of beans were planted, while 2022 saw the introduction of 20 onion varieties. The town’s motto (座右铭) is, “Picking is encouraged — help yourself!”

It’s a community effort, as local citizens are encouraged to help plant and maintain the gardens. This offers an opportunity to socialize as well as to learn about planting, cultivating and harvesting food. “I often drop by to pick some herbs that I’m missing at home. Everything is easily accessible. There aren’t any fences. You just take what you need. The only thing is you have to be quick once the fruits are ripe or they’ll all be gone!” said a local historian.

Andernach may be the first, but it isn’t the only edible city. It’s part of the Edible Cities Network, an EU-funded project connecting green urban food initiatives around the world. Other edible cities include Carthage in Tunisia, Havana in Cuba and Šempeter-Vrtojba in Slovenia. In February 2022, the first Edible Cities Network Conference took place. Dr. Ina Säumel, director of the Edible Cities Network, called it “a unique opportunity to invite researchers and people involved of Edible City Solutions to the same table and unite theory with practice”.

Ultimately, the Edible Cities Network aims to create “greener, more edible and, above all, more livable cities”. It is a response to the pressures of climate change, and a cause for hope.

【小题1】What is paragraph I mainly about?
A.The development of a German city.
B.The popularity of Andernach’s city design.
C.Approaches of planting vegetables.
D.The green food project in Andernach.
【小题2】How did the local historian feel about the project?
A.Satisfied.B.Ignorant.C.Doubtful.D.Discouraged.
【小题3】What can be inferred from paragraph 3?
A.Edible cities hold meetings on a regular basis.
B.German rural areas will also follow the steps.
C.Asia will join the Edible Cities Network soon.
D.Green urban food is in the upward trend.
【小题4】Which of the following could be the best title for the text?
A.Start a green food campaign nowB.Gain easy access to German food
C.Make your cities edible as wellD.Respond quickly to climate change

Have you ever considered all the English expressions that include words about clothes?   Let’s have a look.

People wear pants to cover the lower part of their bodies. We sometimes say that people who are nervous have ants in their pants. Sometimes, people may get caught with their pants down. They are found doing something they should not be doing. And, in every family, one person takes control. Sometimes a wife tells her husband what to do. Then we say she wears the pants in the family.

Pants usually have pockets to hold things. Money that is likely to be spent quickly can burn a hole in your pocket. Sometimes you need a belt to hold up your pants. If you have less money than usual, you may have to tighten your belt.

I always praise people who can save their money and not spend too much. I really take my hat off to them. Yet, as to my own money, I spend it at the drop of a hat.

Boots are a heavy or strong kind of shoes. People who are too big for their boots think they are more important than they really are. I dislike such people.

My father is an important person. He runs a big company. He wears a suit and tie, and a shirt with sleeves that cover his arms. Some people who do not know him will think he is too serious and never shows his feelings openly. But I know that my father wears his heart on his sleeve.

【小题1】If we say someone has to tighten his belt, we probably mean he_______.
A.has done something wrongB.is short of money
C.has put on the wrong pantsD.used to live a rich life
【小题2】Someone who spends his money at the drop of a hat most probably_______.
A.never wastes his moneyB.earns much money
C.spends more than he earnsD.doesn’t save money
