The Day Mother Cried
Coming home from school that dark winter’s day so long ago, I was filled with anticipation. I had a new issue of my favorite sports magazine under my arm. Dad was at work, my sister was away, and Mother wouldn’t be home from her new job for an hour.
I was shocked into stillness by what I saw . Mother pulled into a tight ball with her face in her hands. She was crying. I had never seen her cry.
I approached cautiously and touched her shoulder. “Mother?” I said. “What’s happened?”
She took a long breath and managed a weak smile. “It’s nothing, really. I’m going to lose this new job. I can’t type fast enough.”
“But you’ve only been there three for days,” I said. “You’ll catch on.” I was repeating a line she had spoken to me a hundred times when I was having trouble learning or doing something important to me. She sobbed in silence .
I felt helpless and out of place. At the age of 16 I still assumed Mother could do anything. To provide enough income for my college two years later, Mother was crazy for ways to save money.
A few months ago, Mother arrived home with an old typewriter. It skipped between certain letters. “That’s all we can afford,” Mother said. “It’s good enough to learn on.” And from that day on, immediately after dinner, Mother would disappear into her sewing room to practice. The slow tap, tap, tap went on some nights until midnight. On Monday, she got a job as a typewriter at a radio station. I was not the least bit surprised but she was excited. But on Tuesday Mother looked drawn. I didn’t care honestly.
My shock and embarrassment at finding Mother in tears on Wednesday showed how little I understood the pressures on her. Sitting beside her on the couch, I began very slowly to understand.
“I guess we all have to fail sometimes,” Mother said quietly. I could sense her pain. I reached out and put my arms around her.
A week later Mother took a job selling dry goods at half the salary the radio station had offered. “It’s a job I can do,” she said simply.

But the evening practice routine on the old green typewriter continued.

3 . Winners of the Broadcom MASTERS
Girls took the top prizes at the Broadcom MASTERS, a science competition for middle school students.
Alaina Gassler
Alaina won the $25,000 Samueli Foundation Prize for the project of reducing blind spots in cars. She was inspired to solve this issue by her mother who didn’t like driving her vehicle because its large A-pillar (A柱) design made her feel in danger. “I started to think about how blind spots were a huge problem in all cars,” said Alaina. So she worked on and solved it.
Sidor Clare
Sidor won the $10,000 Marconi/Samueli Award for Innovation, an honor made by Samueli’s generous donation of his 2012 Marconi Society Prize Award. She developed bricks that could one day be made on Mars, so that humans wouldn’t be required to carry building materials with them in order to build there.
Alexis MacAvoy
Alexis won the $10,000 Robert Wood Johnson Foundation Award for Health Advancement, which recognized the student whose work and performance showed the most promise in health-related fields and demonstrated an understanding of the many social factors that affect health.

5 . When you eagerly dig into a long-awaited dinner, it’s traditionally believed that signals from your stomach to your brain stop you eating so much. However, a research team recently discovered that it’s our sense of taste that immediately pulls us back from eating food overly on a hungry day. Stimulated by the perception of flavor, a set of brain cells become active to quickly curtail food intake.
Previous studies have suggested that the food taste may control how fast we eat, but it’s been impossible to study relevant brain activities during eating because brain cells that control this process are located deep in our brains, making them hard to access or record in an awake animal. New techniques developed by the team allowed for the first-ever imaging and recording of a brainstem structure critical for feeling full, called NTS, in an active mouse.
The new study found that when researchers put food directly into the mouse’s stomach, brain cells called PRLH were activated by signals from the gut (消化道), in line with traditional thinking. However, when they allowed the mice to eat the food as they normally would, those signals from the gut didn’t show up. Instead, the PRLH brain cells switched to a new activity pattern that was entirely controlled by signals from the mouth. “It’s astonishing that these cells were activated by the perception of taste,” said researchers. “It shows that there are other components of the appetite-control system that deserves our attention.”
The PRLH-activated slowdown also makes sense in terms of timing. The taste of food allows PRLH to switch their activity in seconds. In contrast, another group of brain cells, called CGC, takes several minutes to respond to signals from the gut. The good thing is that CGC can hold back hunger for a much longer time. These two sets of brain cells interact to work together: one uses taste to slow down eating, while the other signals that you are full.
Understanding how body signals regulate appetite could improve weight-loss programs for the overweight by making use of interactions between signals from different brain cell sets.

6 . After the death of her nature-loving mother, Margaret Renkl tenderly placed in an antique jar the “soft white hair” left behind in her mother’s hairbrush. Years passed. When it no longer carried the scent (气味) she treasured, Renkl laid the hair across a tree branch in her yard. This act was meant as a direct invitation to the birds in her yard, and it was accepted: A bird used the hair for the nest it was building.
Renkl devotes only a half-page to this story, but it conveys the beautiful interaction of human and other animal lives at the heart of The Comfort of Crows. Starting in winter and continuing through the seasonal round, Renkl brings alive in 52 chapters her love for the animals and plants in her half-acre (半英亩) yard in Tennessee and in nearby parks. Equally moving, she admits her desperation at the human-caused crisis the natural world faces, and her determination not to back off.
Her determination is more than lip service. She cures a neighborhood fox against a skin disease, with the help of a trap, a bit of bacon, and advice from an animal doctor; ensures that leaves from the trees in her yard are not gathered so that insects overwinter and hungry birds can dine there; fills a garden with milkweed in support of monarch butterflies.
With these steps, Renkl refuses to give up in the face of human-caused global warming that is changing our environment and harming other species. In these days of climate crisis, the phenomenon of ecological anxiety is real. In order to seize opportunities to help, many of us do require fuel to restore our spirits. Find that fuel in Renkl’s chapters of The Comfort of Crows. The animals and plants so cherished by Renkl need us now more than ever.
1. What is the central theme of Renkl’s The Comfort of Crows?A.Personal preference towards country life. | B.Fond memories of close family members. |
C.Profound disappointment at climate crisis. | D.Amazing interactions between man and nature. |
A.Renkl’s efforts in protecting animals. | B.Renkl’s service in the neighborhood. |
C.Renkl’s attempts to treat an injured fox. | D.Renkl’s determination to preserve the yard. |
A.Indifferent yet realistic. | B.Concerned yet active. |
C.Pessimistic yet tolerant. | D.Regretful yet hopeful. |
A.To introduce the beauty of rural life. | B.To present the daily routine of Renkl. |
C.To recommend an inspirational book. | D.To provide advice on nature protection. |

10 . There is some truth to the old belief that achy joints are a sign that bad weather is on the way. Research shows a relationship between pain levels and changes in weather, particularly for people who suffer from chronic conditions such as arthritis (关节炎).
A2019 UK study analyzed the daily pain logs of 13,000 residents with arthritis. Using GPS data from participants’ smartphones, the researchers found connections between pain and humidity (湿度), air pressure and wind speed. Participants were more likely to experience pains on stormy, windy days and least likely to do so when conditions were dry and calm.
It’s unclear why changes in weather may influence pain severity for some people and not for others. “Everyone experiences pain differently,” says Sin Bevan, chief science officer at Arthritis Society Canada. “There are a lot of factors that could impact pain tolerance, including sleep, stress and depression.”
“It’s a good idea to track your symptoms and how certain weather conditions may affect your pain levels,” says Bevan. “From there you can manage expectations for what can be done on days when symptoms are worse.”
Not surprisingly, there’s evidence that the weather may also impact your mood. There are multiple reasons for this connection, according to Dr Max Pemberton, a UK-based psychiatrist. “Less sunlight affects your levels of melatonin, a hormone (激素) directly involved in mood regulation.”
Besides, bad weather may contribute to social isolation and loneliness because we can’t go outside and do things we enjoy with friends and family, explains Pemberton.
Once you understand how the weather impacts you physically or mentally, there are strategies you can try. For example, if you’re sensitive to cold and damp weather, a hot bath could provide relief for achy joints. Regular exercise — even if it has to be indoors — is also known to improve mood and is an important part of pain control.
