Every kid has their own obsessions (着迷的事情). Dolls, dinosaurs, remote controls, cell phones—they might have a toy box with a wide range of playthings to keep them entertained, but there’s a firm favorite they always reach for first.

Researchers call this phenomenon “extremely intense interests (Ells)”, and have found that they start to emerge at around 18 months of age and are evident in around a third of preschool-aged children. For lots of children, this obsession revolves around (围绕) cars. And although the sex divide in the toy world remains, it’s not only little boy who are drawn to all things with wheels. So what’s the big deal about cars, trucks, trains, and buses?

From age 0-2, children are the sensorimotor stage of development. They are learning by absorbing everything through their senses—sight, touch, taste, smell, hear. Toys and real-life objects like cars are very sensorily engaging. Kids can interact with toy cars, trucks, etc. through spinning their wheels, watching them move in a variety of direction, or hearing the sounds they make.

Plus, kids are just naturally drawn to loud, moving objects. They see the lights on the cars, the rolling wheels, the sound of the engine. Kids will always be drawn to flashy and loud things because that is what engages their brain and sensory systems. Another appeal of toy vehicles is that they’re typically small enough to fit in a child’s hand. And because they can put their cars in their pocket or carry them around, they’re easy to get attached to.

Every child is unique in how they engage with toys, and the reasons for their play style may be diverse and complex. However children often interact with materials in similar ways to how their families interact with them. If a child sees a sibling or parents modeling play with a car going fast down a track, they are likely going to interact with the toy that same way. Ultimately, how your kids play with their toy vehicles could be a little window into what excites them.

【推荐1】Fossils discovered in Liaoning province have challenged the theory that the Archaeopteryx is the earliest known bird.

Research of the fossils led by Pascal Godefroit and his team from the Royal Belgian Institute of Natural Sciences revealed that the dinosaur bird Aurornis xui, like the Archaeopteryx, existed nearly 150 million years ago. Godefroit told British-based Daily Mail, “The evolutionary development shows that dinosaur birds were already diversified in northern China during the Middle-Late Jurassic.”

The study, published in the journal Nature, showed that Aurornis xui was 50 cm in length and had tiny teeth used for hunting and defense, similar to other dinosaurs. Godefroit said the results support a “single origin of powered flight”, which suggests that all dinosaurs that became birds took flight around the same time, and eventually lost hunting and defensive features, like teeth, during adaptation.

Hu Dongyu, a professor at Shenyang Normal University, pointed out that fossils of some dinosaurs show that the legs initially had long feathers, which suggests they assisted wings in flight. “But the long feathers on the legs degenerated as the wings became strong enough. This is not the first time that fossil evidence has showed the evolution path from dinosaurs to birds,” said Hu. “The initial question was whether these dinosaur birds existed before the Archaeopteryx, but as we dig deeper into them, the age became irrelevant. And now the bone of contention is whether all these dinosaur birds are dinosaurs or birds.”

One fossil, found in Liaoning in 2009 and studied by scientists led by Xu Xing from the Chinese Academy of Sciences in Beijing, showed that the earliest dinosaur bird was Anchiornis huxleyi, a flying dinosaur that lived 160 million years ago. Another fossil studied by Xu and his colleagues, also believed to be a dinosaur bird, was named Xiaotingia zhengi. “Aurornis xui, Anchiornis huxleyi and Xiaotingia zhengi are similar dinosaur bird fossils,” Hu added. “The earlier research suggested that all dinosaur birds were dinosaurs, not birds. However, recent research suggests the opposite. So there is a long way to go to draw a conclusion.”

1. What is the topic of the text?
A.The origin of birds.B.The adaptability of birds.
C.The time when dinosaurs appeared.D.The reason why dinosaurs died out.
2. In what way was Aurornis xui similar to other dinosaurs?
A.The speed of its flight.B.The force of its defense.
C.The length of its feathers.D.The feature of its teeth.
3. What does the underlined part “the bone of contention” in paragraph 4 mean?
A.The bones of birds.B.The focus of debate.
C.The similarity of theories.D.The conclusion of research.
4. What does Hu think of dinosaur birds?
A.They were dinosaurs.B.They need further study.
C.They could fly like birds.D.They existed before the Archaeopteryx.

【推荐2】Do you suffer from cybersickness?
The rise of mobile phones has been blamed for a number of social ills, but your smart phone may also be making you physically sick as well. Scientists have identified a condition called “cybersickness”, which they say is the digital version of motion sickness. The phenomenon, which affects up to 80 percent of the population who own smart phones or tablets, leads to feelings of sickness and unsteadiness. It is caused by seeing fast motion on a screen, which covers anything from a car chase in a film to scrolling through web pages on your phone.
The more realistic the visual content appears to you, the higher your chances of getting cybersickness are . The condition was identified in a piece in the New York Times in which British and US experts said that it needed solving. Motion sickness leaves sufferers feeling ill because they feel movement in your muscles and your inner ear but do not see it. The mismatch in digital sickness is the opposite—you see movement on the screen but do not feel it. The effect is the same and the symptoms include a headache, wanting to throw up, confusion and the need to sit down. Often cybersickness shows itself in a subtle way and sufferers put it down to stress or eyestrain.
Steven Rauch, a professor of otolaryngology(耳鼻喉科学) at Harvard Medical School, said: “Your sense of balance is different from other senses in that it has lots of inputs. When those inputs don’t agree, that’s when you feel dizziness and sickness. ”
Some studies that have been carried out into cybersickness found that women are more susceptible than men, the New York Times reported. Those who have Type A’ personalities—meaning they are confident and determined—are more likely to suffer from cybersickness as well. Among those who have reported experiencing the condition have been video gamers who spend hours playing fast paced games. Engineers at Oculus VR, the virtual headset manufacturer, have admitted that digital motion sickness is one of their biggest problems.
1. From the text, we know that cybersickness ______.
A.is completely equal to motion sickness
B.affects up to 80% of the population.

2. What’s the difference between motion sickness and digital sickness?
A.Digital sickness means sufferers see movement but do not feel it.
B.Digital sickness means sufferers feel movement but do not see it.
C.Motion sickness means sufferers see movement but do not feel it.
D.Motion sickness means sufferers don’t see or feel movement
3. What does the underlined word “susceptible” in the last paragraph mean?

【推荐3】Human activities are killing wildlife at an alarming rate, with causes ranging from environmental pollution to the built environment. For bird species, nighttime collisions (碰撞) with power lines are driving significant population decline. But now scientists have come up with a clever way to make the lines easier for birds to spot, without being ugly to humans.

Industry and U. S. Fish & Wildlife Service guidelines recommended that electricity companies mark their power lines with plastic attachments to make it more visible, but birds were still dying. Biologists reported that 300 Sandhill cranes (鹤) perished in one month in 2019 from collisions with marked lines at the Rowe Sanctuary ‘in Nebraska, where the cranes stopped over during their annual spring migration. “We need forward-thinking methods to protect not only large birds that are naturally at greater risk from power lines but also millions of smaller birds,” said Anne Lacy of the, International Crane Foundation.

Bird species can see ultraviolet light (紫外线) at night. So James Dwyer, a wildlife biologist at a consulting firm, EDM, had the idea of using near-visible UV light to brighten power lines. EDM’s engineering team and the Dawson Public Power District developed such light systems and installed them on a tower supporting a power line at Rowe Sanctuary. Over a 38-night period, crane collisions decreased by 98 percent when the lights were on, the researchers reported in a study published online in May in Ornithological Applications.

Richard Loughery, director of environmental activities at the Edison Electric Institute, who was not involved in the project, says the new UV system adds an important tool for use in hotspots where endangered bird species nest and feed.

“I don’t want electricity companies to build lines wherever they want because there’s a new tool,” says biologist Robert Harms of the U. S. Fish &. Wildlife Service, who was not involved in the work. But for existing lines, he says, the UV system could be absolutely amazing.

1. Why was the first method abandoned to protect birds?
A.It couldn’t protect birds migration.
B.It couldn’t prevent birds from standing on the plastic attachment.
C.The used material was hard for birds to spot at night.
D.The used material made more birds come to the power line.
2. What does the underlined word “perished” in paragraph 2 mean?
A.Died.B.Appeared.C.Survived.D.Increased.
3. What was the main reason for choosing UV light to protect birds?
A.It was more economical.
B.It was not harmful to birds.
C.It was invisible to people but not to birds at night.
D.It was a new technology tool for protecting birds.
4. What did Robert Harms think of the UV system?
A.Unnecessary.B.Satisfactory.C.Critical.D.Skeptical.
