When you think of the Arctic, you imagine an icy land of pure white snow. Others imagine it as the last really clean place left on Earth. We have polluted the deepest oceans with plastic trash, 1.
German scientists have recently found microplastics in Arctic snow. 2.Sadly, the scientists found 1,800 pieces of microplastic per liter of snow.
How is plastic pollution reaching the Arctic? According to scientists. "It's apparent that the majority of the microplastics in the snow comes from the air." They fall off plastic objects and are moved by the wind, just like dust. 3.Finding these plastics in Arctic snow means that we may breathe them in. An even higher amount of microplastic was found in the snow around cities.
The high concentrations found in snow samples suggest microplastics, which contain rubber or chemicals used in synthetic fabrics（混合纤维）, may cause significant air pollution.
4.Scientists cannot answer this question for now, according to the world Health Organization. We do know that our bodies cannot take in "large" pieces of microplastics. However, if the plastics are small enough, they can find ways into our bodies and stay there for a long time. What's more, earlier studies have shown that microplastics may contribute to lung cancer risk, heightening the need to further assess the risks of taking them in, the study said.
Microplastics have also been found in rivers and oceans around the world. Previous research has found that they flow over long distances and into our oceans, damaging ecosystems along the way.5.The waste water then flows into rivers and out to sea, where they are eaten by sea animals. If people then eat these animals, it means that we're eating the plastic as well.
A.Are they bad for us?
B.and now it's the Arctic's turn.
C.so we should take action to protect the world.
D.They mix with ice in the air and fall to the ground as snow.
E.Microplastics are pieces of plastic smaller than 5 millimeters.
F.They start in our water when we wash clothes with plastic fibers.
G.Is plastic pollution doing great damage to our global economy?
A butterfly's wings can have many jobs besides keeping the insect in the air. They may be called on to attract mates, to warn potential enemies to stay away, to do other animals or even to provide disguise（伪装）.
All of these roles, though, depend on their colouration—which is unchanging. This plays into the idea that butterfly wings are dead tissue, like a bird's feathers or a mammal's hair. In fact, that is not true. For example, in some species males' wings harbour special cells that release chemicals which attract females.
Nanfang Yu, a physicist at Columbia University, in New York, has been looking into the matter. One of his interests is the optical（光学的）properties of biological materials. That has led him to study butterfly wings in more detail. And, in cooperation with Naomi Pierce, a butterfly specialist at Harvard University, he has now shown, in a paper published this week in Nature Communications, that butterfly wings are, indeed, very much alive.
Initially, Dr Yu and Dr Pierce wanted to know how the insects keep their body temperatures up without their wings overheating.
Unlike birds and mammals, butterflies do not produce enough internal heat to metabolize（新陈代谢）. Instead, they rely on outside heat sources—usually the sun—to bring their bodies up to speed. But their wings, being thin protein membranes（膜）, have a limited thermal capacity. Those wings can therefore overheat quickly if the insects are exposed to the sunlight too long, or, oppositely, can cool down too rapidly if they are flying through cold air.
In their experiments, the two researchers used a laser（激光）to heat up spots on the wings of dozens of butterfly species. When the temperature of the area under the laser reached 40℃ or so, the insects responded within seconds by doing things that stopped their wings heating up further. These actions included a butterfly turning around to minimize its exposure to the laser, beating its wings or simply walking away.
1.What's Dr Yu's discovery about butterfly wings?
A.They contain dead tissue.
B.They are too thin to store heat.
C.They have different functions.
D.They react quickly to high heat.
2.Which of the following is True according to the text?
A.Butterflies metabolize completely with its internal heat.
B.Chemicals from butterfly wings help drive away threats.
C.The color of butterfly's wings keeps fixed.
D.The researchers achieved big in optical properties.
3.How can a butterfly stop its wings overheating?
A.By providing heat itself.
B.By flying through cold air.
C.By removing the source of heat.
D.By adjusting their heating surface.
4.What's the best title for the text?
A.A Research into Butterfly Wings
B.The Jobs of Butterfly Wings
C.Butterfly Wings: Dead or Alive
D.Butterfly Wings Temperature Changes
Screen time increases by 300 percent between the ages of 1 and 3 according to a recent study. In a perfect world, parents would always choose outdoor time over screen time. But for many parents, decreasing screen time isn't as simple as it sounds. That's because screens are increasingly used as an entertainment and distraction（分心）tool for kids which parents think is necessary due to a lack of quality childcare.
The United States government defines affordable childcare as care costing no more than 7 percent of a family's total income, yet more than 40 percent of families say they set aside more than 15 percent of their total income for it, according to a 2019 survey published by Care. com.
Affordable childcare in America is a dream. “Screen time is used as a last substitute for childcare for many families,” says licensed child therapist（治疗师）Katie Lear. “Particularly for parents who work from home, it can be hard to justify hiring a caregiver or paying for daycare. And yet children need to be able to keep themselves occupied during important work calls. Turning on the TV can buy the parent some valuable time during what can be a very tiring day."
If affordable childcare wasn't just a daydream, if the system we have wasn't dependent on two incomes, if parents could actually afford not to work 50+ hours a week, if childcare centers could afford to pay their workers a desirable wage, then maybe, we'd see screen time decrease instead of increase. We know our kids should be interacting with something other than You Tube videos and flash games for hours a week. But before we fix our broken system and before affordable, quality childcare becomes a reality, parents and caregivers are going to do whatever they can to make it, and that includes using screens as passive childcare.
1.Why do parents allow their children to spend much time on screens?
A.To please their children.
B.To make up the lack of quality childcare.
C.To attract kids' attention to classes online.
D.To help children learn about necessary technology.
2.What do the statistics in Paragraph 2 indicate?
A.Childcare workers have high income.
B.Childcare centers are popular in America.
C.Childcare is a heavy burden for parents.
D.Childcare is supported by local government.
3.Why is Lear mentioned in the text?
A.To uncover the reason for screen time as childcare.
B.To prove the advantages of adopting c-products.
C.To present the ways of parents' improving childcare.
D.To explain the benefits of hiring a caregiver.
4.What's the key in reducing children's screen time?
A.Enough company time. B.High income in the family.
C.Turning off the TV. D.Hiring a caregiver.
