But distance learning means lots of screen time.Research has shown that kids who spend a lot of time on screens are more likely to have various health problems and trouble with re

18、ading and language. Yet in the countries still suffering from the epidemic (流行病)，screens are the only safe way for many young people to learn or socialize. Its difficult for kids and teens to navigate this dilemma.In one 2019 study, Taren Sanders, a health scientist at Australian Catholic University

19、 in North Sydney, looked at how kids spent their screen time. His group then investigated whether the type o screen time made a difference in health and school achievements. The researchers sorted screen time into five types: passive (such as watching a movie) , interactive (such as . playing a vide

20、o game), social, educational or something else.Educational screen time was linked to doing better in school and had no bad health effects. More passive screen time was linked to worse outcomes in health and school achievements, Sanders group found, compared with the other categories. But the impact

21、was quite small. Major problems showed up mainly in kids spending more than eight hours a day on screens.The most serious problem caused by too much screen time is that people usually sit still while they are in front ,o a screen.

22、ving?” asks Guerrero, who studies patterns of diseases. “Extended time sitting and not moving around leads to obesity, diabetes, heart disease and other health issues. So an important question to ask yourself is not how much screen time are you getting, but how active are you?Sanders agrees. Overall

26、ss the influence of screen time.D. To analyse the effect of distance learning.DAt any moment, about half the worlds population is wearing denim （牛仔布）. But few realize tiny bits of denim have been adding up to a surprising amount of pollution in water, as a new study shows.Sam Athey, one of the study

27、s authors, says, “Even though denim is made of a natural material cotton it contains chemicals. Cotton fibers are treated with many types of chemicals, she notes. Some improve its durability and feel. Others give denim its distinctive blue color.Athey and her team washed jeans and found that about 5

28、0,000 microfibers come off from each pair per wash. Not all of those fibers make their way into the environment. Wastewater treatment plants catch about 83 to 99 percent of them. Catching 99 percent may sound pretty good. But one percent of 50,000 is still 500 fibers per wash. And since every pair o

29、f jeans is washed again and again, it still adds up to lots of microfibers entering water environments.Denim microfibers showed up in sediment （沉淀物）from the Great Lakes. More of these fibers polluted a series of shallow lakes in southern Ontario. They even turned up in sediment from the Arctic Ocean

30、 in northern Canada. The team found denim accounted for 12 to 23 percent of microfibers in the sediment. There were other microfibers too. But the team focused on denim because so many people wear jeans.Everyone wears jeans so they could be our largest input of microfibers into our streams and soils

31、,“ Athey says. An easy way to limit that is by washing our jeans less often.” Athey grew up thinking she should wash her jeans after every couple of wearings, but most jean companies recommend washing them no more than once a month “The solution is not that you shouldnt wear jeans, she says. We need

32、 to buy fewer denim clothes and only wash them when they truly need it. ”12. Why are chemicals used to deal with cotton according to the passage?A. To lessen it harm. B. To remove its blue color.C. To make it into denim. D. To prevent fibers from falling.13. What does the underlined word them in Paragraph 3 refer to?A. Chemicals B. Microfibers.C. Jeans. D. Plants.14. What is Paragraph 4 mainly about?A The wide uses of denim.B. The types of water pollution.C. The larg
