1 . Types Of Students You Will Meet In College

There are thousands of universities around the world, and each school boasts its own traditions and slogans. Some schools pride themselves on sports, while others emphasize their research facilities. While there are a myriad of differences among each and every school, there will always be these three types of students in class.

The one who sits in the front row

There’s at least one of these people in every single class,whether it’s a required General Education class or an upper division major course. These students always sit in the front row and ask at least five questions every lecture.

They attend all the discussions and office hours, and try to turn in homework at least a week in advance. These are also the people who remind professors about assigned homework and upcoming exams. Nothing bad about being studious, but are they even human?

The one who never studies (but still aces the class)

Standing as probably the most frustrating category of people in this list, these students won’t know about a midterm until two days before. They go to class every once in a while when the class time doesn’t clash with one of their many elaborate social plans, but never pay attention. Somehow, they still ace all their exams and end up with the top grade in the class.

The one who always falls asleep

This person comes to class every day, but somehow never stays awake for more than 20 minutes. You can sometimes hear the occasional snore from a corner of a large lecture hall, or catch their heads nodding like a pendulum near the front of the class if they’re the studious type. But let’s be real here: we’ve all been one of those students at some point.

2 . Do you find yourself looking at your Facebook page or watching YouTube videos instead of getting work done? Are you________your plans for the summer? If you do, you’re not________. Many people do that, including me.

I am in my second year at college. In almost every________, I find it hard to sit still and pay attention. If it’s not________my phone, it’s daydreaming about what my plans are for the weekend. It’s________. I hate it. But I can’t control myself. I pick up my cellphone to________my emails and messages without________it. And I find myself________ news on social media, ________knowing what’s going on around me.

Yes, we live in a digital age where we even use________in the bathroom. Because of using digital devices, our attention span (注意力持续时间) has become much________than before. Yes, that’s true—a recent________made by Microsoft Corporation shows that people now usually________concentration after eight seconds. Interestingly, I usually find it________to study around people who are also studying. I_________can focus more that way.

My________ to students reading this is that when it comes to study, you’d better turn off all digital devices. Our brain________to focus on things that are right in front of us. Removing out distractions altogether, especially________you get a lot of them, seems to be one of the best________of doing better in your work.

There is no easier solution to this; you must turn off digital devices, or you won’t focus. It just takes some________.

3 . A new study reveals that pigeons (鸽子) can tackle some problems just like artificial intelligence, enabling them to solve difficult tasks that might challenge humans. Previous research has theorized that pigeons employ a problem-solving strategy, involving a trial-and- error approach, which is similar to the approach used in AI models but differs from humans’ reliance on selective attention and rule use. To examine it, Brandon Turner, a psychology professor at the Ohio State University, and his colleagues conducted the new study.

In the study, the pigeons were presented with various visual images, including lines of different widths and angles, and different types of rings. The pigeons had to peck (啄) a button on the right or left to indicate the category to which the image belonged. If they got it correct, they received food; if they were wrong, they received nothing. Results showed that, through trial and error, the pigeons improved their accuracy in categorization tasks, increasing their correct choices from about 55% to 95%.

Researchers believed pigeons used associative learning, which is linking two phenomena with each other. For example, it is easy to understand the link. between “water” and “wet”. “Associative learning is frequently assumed to be far too primitive to. explain complex visual categorization like what we saw the pigeons do,” Turner said. But that’s exactly what the researchers found.

The researchers’ AI model tackled the same tasks using just the two simple mechanisms that pigeons were assumed to use: associative learning and error correction. And, like the pigeons, the AI model learned to make the right predictions to significantly increase the number of correct answers. For humans, the challenge when given tasks like those given to pigeons is that they would try to come up with rules that could make the task easier. But in this case, there were no rules, which upsets humans.

What’s interesting, though, is that pigeons use this method of learning that is very similar to AI designed by humans, Turner said. “We celebrate how smart we are that we designed artificial intelligence: at the same time, we regard pigeons as not clever animals,” he said.

4 . For Caribbean box jellyfish (水母), learning is literally a no-brainer.

In a new experiment, these animals learned to spot and avoid obstacles (障碍物) despite having no central brain, researchers report in Current Biology. This is the first evidence that jellyfish can make mental connections between events and change their behavior accordingly. “Maybe learning doesn’t need a very complex nervous system, but rather, learning is an essential part of nerve cells,” says Jan Bielecki, a neuroethologist at Kiel University in Germany. If so, the new finding could help trace how learning evolved in animals.

Bielecki and his colleagues wondered if Caribbean box jellyfish could learn that low-contrast objects, which might at first seem distant, were actually close by. The team put 12 jellyfish into a round tank surrounded by low-contrast, gray and white stripes. A camera filmed the animals’ behavior for about seven minutes.

At first, the jellyfish seemed to interpret the gray stripes as distant roots and swam into the tank wall. But those collisions (碰撞) seemed to lead the jellyfish to treat the gray stripes more like close roots in dirty water, and the animals started avoiding them. The jellies’ average distance from the tank wall increased from about 2.5 centimeters in the first couple of minutes to about 3.6 centimeters in the final couple of minutes. Their average collisions into the wall dropped from 1.8 per minute to 0.78 per minute.

“I found that really amazing,” says Nagayasu Nakanishi, an evolutionary biologist at the University of Arkansas in Fayetteville, who has studied jellyfish nervous systems but was not involved in the new work. “I never thought jellyfish could really learn.”

Neurobiologist Björn Brembs views the results more cautiously, noting the small number of jellyfish tested and the variability in their performance. “I want this to be true, as it would be very cool,” says Brembs. Experiments with more jellyfish could convince him that the animals really do learn.

5 . In our family, the presents we gave one another were almost always homemade. I thought that was the definition of a gift: something you made for someone else. We made all our Christmas gifts: piggy banks from old bottles, and puppets from retired socks. It didn’t seem like a hardship to me; it was something special.

My father loves wild strawberries, so for Father’s Day my mother would almost always make him strawberry cakes. While we kids were responsible for the berries, we each got an old jar and spent the Saturday before the celebration in the fields, filling it as more ended up in our mouths. Finally, we returned home and poured them out on the kitchen table to sort out the bugs. I’m sure we missed some, but Dad never mentioned the extra protein.

In fact, he thought that was the best possible present, or so he had us convinced. It was a gift that could never be bought. As children raised by strawberries, we were probably unaware that the gift of berries was from the fields themselves, not from us. Our gift was time, attention, care and “red” fingers.

Gifts from the earth or from each other establish a particular relationship, a duty of sorts to give, to receive, and to exchange. The field gave to us, we gave to my dad, and we tried to give back to the strawberries. When the berry season was done, the plants would send out its red runners to make new plants. So I would weed out little fields of ground where the runners touched down. Sure enough, tiny little roots would emerge from the runner and by the end of the season there were even more plants, ready to bloom under the next strawberry season. No person taught us this — the strawberries showed us. Because they had given us a gift, an ongoing relationship opened between us.

7 . Automation certainly has its advantages. I am grateful for my cellphone that _______performs services. But I also miss the interactions with people that these devices have _______. The most precious byproduct of these interactions was the unplanned, friendly jokes that often _______.

I recently decided to spend a day _______ all of my goals in a non-digital manner. So I rose early and _______ on my visit. I began by going to the bank. When I entered the hall, I found the _______ was mine: I was the only customer, with three clerks at my _______. After my transaction we chatted for a few minutes, sharing news about children.

Our program offers different courses that help students understand the basic rule of accounting. There are a lot of career choices in accounting, such as investment banking and management consulting.

10 . Let’s say you’re in the far future and you’re looking for evidence of previous civilizations. Where would you look? The first place would be in the rocks. Rocks keep time. Recently, the discovery of rocks made from plastic debris (碎片) in Brazil’s volcanic Trindade Island is sparking alarm. Melted plastic has become twisted with rocks on the island, which researchers say is evidence of humans growing influence over the Earth’s geological cycles.

Plastic rocks have been previously found in various parts of the world. Researchers documented plastiglomerates-rock, sand and other debris fused together by melted plastic-in Hawaii in 2014, for instance. Another human-made and plastic-based rock is pyroplastics. Described in 2019 from the shores of Cornwall in southwest Britain, pyroplastics form from burned plastic waste. In laboratory experiments with white or colored plastic pieces, if burned, the plastic melts and forms a gray or black mass. resembling at first glance a rocky pebble. According to geophysicist Douglas Jerolmack, “all around the world where there’s trash being openly burned in mass quantities, you can imagine there are even larger melted plastic deposits” where plastiglomerate could form.

Plastic pollution making its way into the formation of rocks suggests humans are having an effect on what was previously considered a natural occurrence, said Santos, who along with others is continuing research into plastic pollution on Trindade Island. “This is new and terrifying at the same time, because pollution has reached geology, ”Santos told Reuters. The finding of plastic rocks also suggests, some experts say, that a new geological epoch has begun: The Anthropocene epoch. Regardless of whether this represents a new epoch, Santos said, “the pollution, the garbage in the sea and the plastic dumped incorrectly in the oceans are becoming geological material preserved in the Earth’s geological records.”

The researchers are yet unsure of the environmental impacts of plastic rocks. Burned plastic can contain high concentrations of potentially toxic elements, like lead and chromium, derived from the pigments used to dye the plastic material. Buried in the ground, plastic has the potential to survive millions of years and even enter the geological record.
