阅读短文,按照题目要求用英语回答问题.
As my kids' summer vacation comes to an end, I find myself wanting to spend every moment with them. This past week I've been feeling guilty every time I schedule something that doesn't involve them, so I haven’t been doing much for myself. But the other day, I had a beauty treatment that I'd scheduled for over a month. I was so looking forward to it when I scheduled it, but as it approached I thought about cancelling it.
As I was leaving home, I told my kids how I was going to miss them and that I would hurry back. My daughter stopped her game, looked up at me and said, ''Oh, Mother, just go. You need to get your mood up again. '' '' Getting your mood up again'' is my daughter's way of telling me to leave home and come back with a better version of myself because it was taking a heavy toll on her too.
In that one sentence, she was telling me that she noticed I’d been running on fumes(烦恼). She was letting me know she could feel my moodiness and irritation that stemmed from not taking the time for me because I was trying to so hard to be present for her and her brothers.
It occurred to me that I'd been neglecting care for myself because I thought my kids should come first. However, in reality, my kids just want me to be happy, even if that happiness means I'm not with them all the time. Our kids would rather have parents who are smiling and feel somewhat rested than spend their days listening to their parents sigh and complain.

Humans once opposed coffee and refrigeration. Here’s why we often hate new stuff.
Humans have a habit of deliberately delaying their own progress. From coffee to mechanical refrigeration to genetically altered food, history is littered with innovations that caused resistance before they become fixtures in everyday life. But the past 600 years of human history help to explain why humans often oppose new technologies and why that pattern of opposition continues to this day. Calestous Juma, a professor of Harvard University, explores this phenomenon in his latest book, Innovation and Its Enemies: Why People Resist New Technologies.
Among Juma’s claims is that people do not fear innovation simply because the technology is new, but because innovation often means losing a piece of their identity or lifestyle, and separating people from nature or their sense of purpose—— two things that are fundamental to the human experience.
Juma identified in his research three key sources of opposition to innovation: those with commercial interests in existing products, those who identify with existing products, and those who might lose power as a result of change. The first group is perhaps the most obvious. Many industries have been disrupted by innovation. Just take a look at the pointless efforts of music publishers to stop the shift to digital music. Some consumers might oppose an innovation because the existing product is deeply rooted in their identity, culture or customs. Britons preferred tea time at home to sitting in a coffee shop, for example. Finally, the emergence of new technologies can also result in a shift in economic and political power, redistributing wealth and influence away from some groups, and toward others. The expansion of tractors （ 拖拉机） and other mechanical equipment reduced the need for farm labor, and the shift in population away from rural areas had significant political implications.
Humans make decisions about new innovations with their instinct rather than evidence. Opponents and enthusiasts of a new technology will often make shocking claims to support their arguments. Sometimes these claims are rooted in fact; other times they are not. People once claimed coffee could make you sterile （不育的）. Juma said beneath those arguments was typically an instinctive fear of new technologies, rather than a reasoned response. “People react intuitively, and they collect the evidence to support what they’re doing,”Juma said. “They see a new product and there is an emotional reaction to that product because it challenges their outlook on the world. This has been the story with almost every new product.”
Historically, technologists have been more concerned with the functionality of the products they create, paying less attention to the implications it may have on society at large, Juma contends. Fortunately, that may be starting to change.

The moon may shine white above us most nights of the year, but how much do we know about Earth’s neighbor and what lies beneath its surface? Scientists are aiming to find out.
On Jan 3, 2019, China’s Change 4 spacecraft landed on the far side of the moon a first for humanity. It released a small probe（探测器）,Yutu 2, or Jade Rabbit 2, which began to search beneath the moon’s surface using Lunar Penetrating Radar（探测雷达）. These radio signals can reach 40 meters underground, three times the depth of the Chang’e 3 lunar probe launched in 2013 for the near side of the moon, China Daily reported.
In a study published in the journal Science Advances, researchers found that the lunar soil’s top layer on the far side of the moon was much thicker than expected ﹣ about 40 meters. Other scientists only expected about 6 millimeters of soil based on NASA observations during the Apollo moon landings, according to The New York Times.
“It’s a fine, dusty, sandy environment, said one of the authors of the study, Elena Pettinelli, a physics and mathematics professor at Rome Tre University, Rome.
Yutu 2 is specifically exploring the Von Karman crater（大坑）,a large hole that’s 180kilometers wide and also the landing site of Chang’e 4. It’s part of an even larger, older crater spanning more than 1,770 kilometers.
“The subsurface at the Chang’e 4 landing site is very complex,” said Li Chunlai, a research professor and deputy director﹣general of National Astronomical Observatories of the Chinese Academy of Sciences. Observations suggest that the subsurface material is totally different than the previous landing site of Chang’e 3, she said.
Radar waves revealed various layers beneath the moon’s surface: grainy（ 颗粒状的）material, boulders（岩石）,and further layers of fine and coarse（粗糙的）particles. This information is helping scientists to gain new understanding of the moon’s history and formation, as well as volcanic activity and lunar impacts.
Yutu 2 is the longest﹣working rover（巡视器）on the moon, but it won’t last forever. China plans to launch the Chang’e 5 probe later this year, Xinhua News Agency reported. The spacecraft is expected to bring pieces of the moon back to Earth for closer study.

During the outbreak of novel coronavirus, cities are locked down and borders are closed. Science, on the contrary, is becoming more open. And this “open science” is already making a difference.
Soon after the epidemic started in China, a research team from Fudan University in Shanghai successfully sequenced（测定序列）the DNA of the virus. But they didn’t keep the information to themselves. Instead, they placed the sequences on GenBank, an open-access data platform, so researchers around the world could download them for free and start studying the virus.
Due to this openness, pharmaceutical（制药的）companies across the globe are now able to work simultaneously to develop a vaccine. “There may be room for multiple different vaccines for different purposes and different age groups,”Amesh Adalja, a senior scholar at the Johns Hopkins University Center for Health Security in the US, told Al Jazeera.“The bigger menu we have of vaccines, the more resilient（有适应力的）well be against coronavirus outbreaks in the future. ”
Major drug companies around the world are also sharing their study results. Remdesivir, a drug originally developed by US company Gilead Sciences to treat Ebola, s found to be promising in fighting against the novel coronavirus. Currently, two trials of the drug are already underway in China, and the results might be available as soon as April, according to The Verge.
This openness in science is going to be even more crucial in the future. With climate change, increasing globalization, and population shifts, epidemics will not go away, and might even become more frequent, Dan Barouch, a Harvard Medical School professor, told Harvard Magazine.
He said, “No one group can do everything. It has to be a coordinated（合作的）approach. But I do think that the world has a greater sense of readiness this time to develop knowledge, drugs, and therapeutics（疗法）very rapidly.
Every epidemic is indeed a crisis, but it can also be a learning opportunity. One redeeming（补偿的）factor of the COVID﹣19 outbreak is that it is helping science adapt for the better.
