The idea of being quarantined (隔离)hadn't seemed like a major issue until we all began to realize all of the things that get taken away when school goes. We had taken our "normal" lives for granted and this pandemic (流行病)was proof.1. Throughout our entire educational lives, we students have always jokingly said we wanted school to be cancelled. We didn't realize, however, that all the activities associated with being in school would be taken away too. School has an influence on so much more than we actually think.2.
While in my room, my sixth-grade cousin opened my door and expressed how she didn't want school to be cancelled because it was the only reason she left the house.3. This is when I began to acknowledge the true impact school has even on the youngest of children. As a sixth-grader, her only known duty so far was to go to school, learn, maybe participate in a sport or two, and socialize with others. When eating dinner my uncle shared with us that he has no work until April 15. My other aunt and uncle now had to play a larger role than ever imagined in the education of their children. Without one-on-one interaction with a teacher, it's crucial to ensure that their kids of ages 4 and 7 continue learning. During this school closure, parents and students alike have noticed the direct effect social media has on our reactions.4. Many of these opinions either contribute to hysteria (歇斯底里)or attempt to tell us that we may be overreacting.
5. This pandemic has effects of all different levels of significance, many of which can never be replaced nor made up. The death toll it has worldwide is even more frightening to think about. Everyone is affected in one way or another by this crisis, but let us not forget what school has taught us about ourselves as a community ... that we are stronger together.
A.Initially, everything seemed to be under control.
B.She explained how she would be bored without school.
C.It has provided us with friend groups, hobbies and passions.
D.Since this didn't affect us at all, we continued about our daily lives.
E.Opinions of all sorts are broadcast regardless of the accuracy they contain.
F.We took for granted the simplicity of walking across a stage with a diploma in our hands.
G.However, the impact the coronavirus has had on the world is a generation-changing event.
When a laptop or smartphone battery starts losing its power, the only options are to buy an expensive replacement or just keep it plugged in all the time. But a woman Mya Le Thai may have found the solution to this problem.
Thai was frustrated that the batteries for her wireless devices degraded (退化) over time, until they failed to charge fully. She did not like having to keep her laptop connected to an electrical outlet to keep it powered on. So, she decided to do something about that problem. At first, she and her team at UC Irvine thought about inventing a new battery. But as they experimented, Thai discovered something that might permit lithium-ion (锂离子) batteries to last forever.
Lithium-ion batteries power most wireless devices. Over time, the batteries lose the ability to hold a charge. Most of these batteries have a lifespan of about 7,000 charging cycles before they die. One of the reasons lithium-ion batteries degrade is their use of nanowires to carry electricity. Nano wires are extremely thin. A human hair is thousands of times thicker, for example. Nano wires are extremely efficient carriers of electricity, which makes them useful in batteries.
But, Thai had a theory — the nanowires might last longer if covered with a gel (凝胶). She and her team tested this theory. “It was a long process and a lot of work,” Thai said. The team tried many coverings for the wires. PMMA, a type of plastic, was one of them. The nanowires were coated with PMMA and cycled through charging 200,000 times. The PMMA-coated nanowires showed no evidence of damage. The results suggest that batteries could last forever without losing charging ability.
Thai hopes to continue her research to understand why this gel works so well and to see if any other gel could create better results and she is enjoying the publicity about her discovery. She said she never expected her research to get media coverage. “It’s kind of cool,” she said. “I’m really glad people are showing interest in my work and not just in the work itself; but also in technology and energy.”

C.The options of batteries for wireless devices D.The reasons for batteries degrading
Sleepiness and boredom lead to yawning (打哈欠), so it has long been believed that the action makes us feel more awake by stretching the muscles surrounding the lungs, or by bringing more oxygen to the blood and the brain. Yet in tests, breathing air with high levels of carbon dioxide or even pure oxygen made no difference to the frequency of yawns.
Another theory, proposed by the French physician Olivier, is that yawning improves the circulation of the fluid (液体) that surrounds the brain. As a result, we can focus better on a task. This might explain why athletes often yawn naturally before they compete.
Recently, though, a new explanation has appeared: Yawning is a way to cool the brain. Experiments led by Gordon Gallup at the University at Albany showed that people yawned far less when their head was cooled by a cold pack compared with holding a heated pack to their forehead The temperature of the brain rises when we are tired, so it is possible that yawning is a way to protect the brain from overheating due to tiredness.
But a strange thing is that when we see another person yawn, we catch it too. In other words, yawning is contagious.
How can we make sense of these different types of yawning? It’s possible that contagious yawning is something different, and might have a social purpose. Steven Palek and his colleagues at the University at Albany say that contagious yawning may be linked to our ability to understand what others want to do. If you are good at reading others’ facial expressions you are more likely to “catch” a yawn. Therefore, lonely people tend to be less affected by yawing, according to research by Atsushi Senju, now at Birkbeck, University of London.
So the simple act of yawning tursout to be surprisingly complex Has this research made you yawn yet?

2.The underlined word “contagious” in Paragraph 4 is closest in meaning to _________.
A.Infectious B.Influential
C. Attractive D.Comfortable
3.How is the passage mainly developed?
A.By making comparisons.
B.By listing different figures.
C.By providing explanations.
D.By telling personal experiences.
Deciding to get her money’s worth out of the wedding dress on which she spent over $1,000, an Australian woman has been wearing her wedding dress, a year after her wedding.
43-year-old Tammy Hall adopted a new lifestyle—anti-consumerism (反消费主义) lifestyle in 2016, after a trip to India opened her eyes to how much we as a society consumed. She decided not to buy any new clothes or footwear for a whole year after she returned home to Adelaide, in Southern Australia, and she managed to make it.
But last year, as her wedding day approached, she faced a dilemma. She wanted to look good on the most important day of her life, but how could she spend a small fortune on the wedding dress she would only wear on that day?
“In the end I decided that if I was going to get a wedding dress, I’d make sure I could get my money’s worth,” Hall tells PA Real Life.
“The first time I wore it after the wedding was to vote in the Australian election in early 2019,” the 43-year-old adds. “Since then, it’s been to all sorts of places. Wearing it on a crowded train was especially funny, but I’ve worn it to do housework, to football games and to the gym.”
Hall says that she has got some strange looks from people, but no irritating comments. It may have something to do with the fact that the dress is not the fanciest, but she believes people are just too reserved to say anything. Anyway, she doesn’t really care, because she knows she has to hit the goal she has set and wearing the dress multiple times is the most reasonable way she could think of to make the most of her wedding dress.
Hall now plans to wear her wedding dress on a trip to Iceland that she and her partner will take nest summer.
1.Why did Tammy Hall adopt a new lifestyle?
A.To adapt herself to Indian life. B.To save money for her next trip.
C.To cut down her consumption. D.To get prepared for her wedding.
2.What did Tammy Hall do to get her money’s worth out of her wedding dress?
A.She brought fun to people with it B.She wore it repeatedly in daily life.
C.She tried to wear it to earn money. D.She got it exchanged again and again
3.What can we infer about Tammy Hall?
A.She has been struggling to make ends meet.
B.She has influenced people’s lifestyle widely.
C.She values her wedding dress less than her trips.
D.She is determined to turn her ideas into practice.
