3 . A new study on 26 chimpanzees (黑猩猩) from zoos around the world found that chimpanzees can recognise family members and long lost friends even after decades of separation.

The participating chimpanzees were given juice while staring at a screen flashing side by side photos of other chimps. One animal from each pair of photos had lived with the group for at least a year, while the other was a stranger. An eye-tracking camera recorded where the participants were looking and for how long. Data showed their eyes rested longer on familiar groupmates, suggesting “rich recognition of each other.”

There is also evidence that they became more intent when shown a picture of a chimpanzee with whom they’d had more positive interactions, compared with conflicting relationships.

In the most impressive case, a 46-year-old chimpanzee named Louise repeatedly demonstrated “intense” attention upon seeing photographs of her sister Loretta and nephew Erin, whom she hadn’t seen in more than 26 years. The team said Louise’s results represent the longest-lasting social memory documented in any non-human animal to date.

“We tend to see ourselves as unique special creatures with incredible intellectual (智力的) capacities that are very different from other animals on earth,” said Laura Simone Lewis, a postdoctoral fellow in Berkeley’s psychology department and lead author of the study. “This study is showing us how similar we are to chimpanzees.” She noted that the findings support the theory that long-term social memory in humans and modern day chimps has come from “our last common ancestor that lived somewhere between 5 to 7 million years ago” who also likely had long-term social memory.

Now that they have definitive evidence that these endangered species possess long-term social memories, researchers have more questions, including whether chimpanzees miss the individuals they’re no longer with, especially their friends and family. “Our study doesn’t determine they are doing this, but it raises questions about the possibility that they may have the ability to do so,” Lewis said.

Tomato Changed My Life

Doing things-without being planned was never my strength.

As a 14-year-old, I would refuse to go for walks around the block with my friends if I was the least bit behind in my schoolwork.

Unlike most teenagers, I lived not in my room, but in an unused kitchen upstairs where I spread my books and papers on a large round table. I spent considerable time there, working continuously for hours, and my mother worried. She would try to lure (引诱) me away. “Come and watch the parade!” she would call from downstairs. “All neighbors are out there!” She thought of all kinds of tricks-the swimming pool, ice cream, stray cats and turtles-to remove me from my -studies, but nothing ever worked.

Later, in college, the pattern continued. The library and my college dorm replaced the unused kitchen at home. When spring came along friends would stop by my dorm or peer into my library room to persuade me to play Frisbee on the lawn. “No, I would almost always say.” I have too much to do.

My college study days were gone, but not my need and love for schedules. My friends and sisters tried to keep me away from my plans, but they were hardly ever successful.

This summer, though, while house sitting for my parents, I was persuaded to change my plans in the most unexpected way. The sight of tomatoes growing in my mother’s garden lured me out of my tightly scheduled world. They drew me with the power of a lover’s gaze. Hundreds of them were turning ripe and red by the minute, decorating the garden like decorations on a Christmas tree.

“If I have time, I’ll make tomato sauce (番茄酱).” I told myself. But my long week in the house by myself was already filled with things to do: writing, and finishing a project that I brought home from the office.

Then, watching the fascinating tomatoes continuously falling to the ground in ever-greater numbers, again I mentally argued about all the things I had planned and needed to do.

7 . 阅读下面短文, 在空白处填入1个适当的单词或括号内单词的正确形式。

The best way     1     (ensure) your good, usable clothing doesn’t become waste is to increase the chances it ends up with someone     2     wants it.

First, don’t wait too long if you choose to donate clothing to an organization, big or small.     3     sooner people donate their unwanted items, the more demand there is     4     them.

Wherever you donate, ensure clothes are clean and dry. If it     5     (damage) or stained, don’t send it to thrift shops (廉价旧货店). They don’t have the capacity to do     6     (repair). Besides, it not only creates a     7     (finance) burden, but defeats the purpose of the charitable action.

Find an organization that focuses on the products you’re looking to give. I Support The Girls, a non-profit, for example, collects and donates millions of     8     (gentle) used bras. Founder Dana Marlowe says they are among the most in-demand but least     9     (donate) products.

You can also deal directly with people     10     (look) to use your clothes. This could be in a yard sale, your local Buy Nothing Project, or a local online giveaway group. It can take time and there’s a carbon cost: shipping is required to get to the buyer, or to the warehouse then to the buyer.

9 . As AI becomes popular, researchers have noticed its influence on the environment. Training an AI system requires huge computing power and electricity, and the resulting CO₂ emissions (排放) are one way AI affects the environment. But its environmental effect is more than its carbon (碳)footprint.

Jesse Dodge, a scientist at the Allen Institute, says, "The influence of Al systems is going to be from their applications, not the cost of training them." David Rolnick, a computer scientist at McGill University, compares AI to a hammer (锤子) “The main effect of a hammer is what is being hammered,” he says, "not what is in the hammer." Just like a hammer which can either destroy things or build a house, Al can hurt or help the environment.

In 2019, ExxonMobil, an oil company, said it would use Microsoft’s app Azure. With the Al technology, it would increase its production and create billions of dollars. This means Microsoft's AI is directly contributing to greenhouse gas emissions. This is not the only AI application that could be environmentally harmful. AI behind the ads that jump out on Instagram or Facebook pages pushes customers to spend more on products like clothes. This in turn causes more emissions through more production and delivery.

But on the other side of the coin, there are AI applications that can help deal with environmental problems, such as the destruction caused by hurricanes. One such application is xView2, a program started by a U. S. organization. It can recognize buildings damaged and people trapped in natural disasters, reducing danger and saving time for rescuers.

AI could be a valuable tool in the fight against climate change—if the Al industry can reduce its harmful climate effects. "Both AI and climate rules have roles to play." Rolnick says. When creating Al rules, he suggests considering its applications, emissions, and other production costs. Further, Dodge adds that those AI professionals should help set up some value systems to limit the technology's use.
