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.

In the 1970s, chemist James Lovelock and microbiologist Lynn Margulis developed the Gaia hypothesis（盖亚假说）: all organic and inorganic components on the planet are part of one self-regulating system, working to maintain life on earth. Scientists agree that we need take significant action to control emissions（排放）. But where scientists and popular movements have thus far failed to convince the world to act, it seems that Mother Earth may have succeeded, with the never-before-seen COVID-19.
COVID-19 is estimated to have reduced carbon dioxide emission in China by a quarter. It caused factories to shut down, and slowed construction activities. Recent analysis shows a 70 percent drop in flights in February compared with January. And even getting into a car and going to a restaurant, shopping mall, or concert poses a risk of infection, which means that many people are choosing to stay at home and are consuming less, resulting in a significant reduction of their carbon footprints.
Of course, China and the rest of the world will hope to restart normal production and consumption as soon as the virus is under control. However, some positive measures have already been taken as a result of COVID-19. As the virus is thought to originate from wildlife, Chinese authorities are revising laws and regulations regarding the country's massive wildlife trade in order to prevent future epidemics（流行病）—a win for biodiversity.
The deaths of thousands of people worldwide should also serve as a lasting reminder of the fragility of life. We humans frequently ignore or repress uncomfortable thoughts of death and extinction. We would rather get on with our lives as usual, thinking everything will somehow work out in the end. Only in the face of suffering and death are we forced to view the bigger, longer-term perspective—and this is what is needed in order to react appropriately to climate change. COVID-19 has sent alarm bells ringing throughout the world.

2.What is the second paragraph mainly about?
A.The unexpected benefit of COVID-19.
B.The economic influence of COVID-19.
C.The preventive measures for COVID-19.
D.The possible causes of COVID-19.
3.What does the underlined word "repress" in the last paragraph refer to?
A.Control. B.Hold.
C.Vary. D.Test.
4.What does the writer want to tell us in the text?
A.It's urgent to fight the virus.
B.The virus has caused many deaths.
C.Life is fragile in face of disasters.
D.Action is needed for climate change.
Four Inspiring Movies
Forrest Gump（1992）
Forrest Gump is a simple man with a low IQ but good intentions. This movie follows the fictional story in which the simple man makes his way through some of the more turbulent（动荡的）times from the 1960s through 1980s. This film took home six Oscars, inspired a “Weird Al” song, and proves that a big heart is the most important thing.
It's a Wonderful Life（1946）
No movie list would be complete without a nod to the past. Let's go with this Christmas classic, about a man with serious financial troubles who intends to commit suicide（自杀）by jumping off a bridge. His guardian angel Clarence Odbody stops him and tells him what life would have been like for those close to him had he never been born. Realizing how much he means to others, he rushes back home and all sorts of happy, inspirational, Christmassy things happen.
Dead Poet's Society（1990）
John Keating（Robin Williams）is a high school English literature teacher at a famous all-male boarding school who gets into trouble with the school administration after encouraging his students to challenge authority and think for themselves. It is certainly inspirational, if not also frustratingly sad.
A Beautiful Mind（2001）
This movie tells the story of John Nash（Russell Crowe）, a professor at Princeton, a US university, who revolutionized the field of game theory and fell into madness as a result of paranoid schizophrenia（精神分裂症）.

Most of us have recently experienced quarantine (隔离) to minimize the risk of meeting somebody who may be carrying the virus. It is certain 1. being under quarantine is no fun. However, with our access to food, 2. (deliver) services and the entertainment 3. (offer) by the internet, we're actually very lucky. Let's take a quick look at the history of quarantines.
The idea of quarantining sick people dates 4. ancient times. Yet the word "quarantine" first came into use in the 14th century Europe during the Black Death.

(suspect) to be harboring the plague (瘟疫)，it was sent to 9. offshore quarantine and ordered to wait there for 40 days when those abroad either recovered, or 10. (likely), died. The waiting period gave rise to the term quarantinario, from the Italian word for 40.
