2 . Everyone “talks” with their hands at least sometimes. Some people’s hand-talking, or gesturing (手势) matches their messages well. Other people like to make gestures that can be confusing. And still others don’t use their hands much at all. No matter which group you are in, it’s important to pay attention to your hand gestures while you are communicating. And also remember hand gestures can have cultural meanings.
A few years ago, I was a speaker at a conference in Lisbon, Portugal. It was my first time in Portugal, and I became immediately fond of the special pastries (糕点) that Lisbon and Portugal are known for. One morning I went into a bakery and ordered two of the pastries. I did so by holding up two fingers, similar to the “victory” or “peace” gesture in the United States. The person behind the counter put three pastries in the box. I later learned that the gesture for two would raise thumb and index finger. Even though my thumb wasn’t showing, the person behind the counter thought I was signaling for three.
I was lucky that I didn’t get into more trouble than an extra pastry. Many hand gestures are not universal. Before speaking in a country that you are not familiar with, do some research to find out which gestures might be misunderstood, not understood at all or rude.

3 . The drive to create the new is part of our biological makeup. We build cultures by the hundreds and new stories by the millions.
Through the history of human activities, prior art promotes the creative process. Before 1908, each vehicle was custom built, with different parts assembled in different places and then painstakingly brought together.
However, on closer inspection, Cicoria also turns out to rely on the raw materials around him. He recalls that, after his accident, he developed a strong desire to listen to nineteenth-century piano music. It is difficult to know what the lightning strike did to his brain, but it is clear that he rapidly absorbed these musical products.
We humans are always waiting for the creative lightning to strike.
A.However, creative ideas evolve from existing memories and impressions. |
B.We surround ourselves with things that have never existed before, while pigs and llamas and goldfish do not. |
C.But is there any moment when someone is suddenly struck by an idea that comes from nowhere? |
D.But Henry Ford came up with a critical innovation of streamlining the entire process. |
E.It shares the same structure and progression as other paintings. |
F.No doubt the non-musician surely managed to compose due to the sudden idea flashing through his mind. |
G.His sudden desire to compose may have come from nowhere, but his basic creative process did not. |
4 . Not much trash and almost no plastic actually gets recycled. About a third of U.S. garbage gets recycled, according to the Environmental Protection Agency’s most recent estimate. The rest goes to landfills, which release greenhouse gases into the atmosphere and pollute their surroundings.
To make recycling easier, many U.S. cities don’t ask Americans to separate paper, glass, metal and plastic. They just ask people to put anything recyclable into one bin and let waste plants do the sorting. But waste plants don’t catch everything. AI is now an essential tool for the world’s waste management leaders. Greyparrot, a tech company has already installed more than 100 AI trash spotters in about 50 sorting facilities.
Greyparrot’s device is, basically, a set of visual and infrared (红外线的) cameras hooked up to a computer, which monitors trash as it passes by on a conveyor belt and labels it under 70 categories, from loose bottle caps to books to aluminum cans. Waste plants could connect these AI systems to sorting robots to help them separate trash from something recyclable more accurately. They could also use the AI as a quality control system to measure how well they’re sorting trash from something recyclable. That could help plant managers adjust their production lines to cover more recyclable objects, or cheek that a bundle of recyclable objects is free of pollutants, which would allow them to sell at a higher price.
In the next few years, some recycling companies plan to retrofit (改良) thousands of material-recovery facilities with Al trash-spotting tools. Of these companies, Bollegraaf has built thousands of these facilities, including 340 in North America, accounting for a majority of the recovery plants in the world.
The trash-spotting computers could one day help regulators punish companies that produce tsunamis of non-recyclable packaging because the AI systems are so accurate that they can identify the brands on individual items. Putting the AI tools in thousands of waste plants can raise recycling percentage. If the needle can be moved by even 5 to 10 percent, that would be a phenomenal outcome for greenhouse gas emissions and environmental impact.
