I opened the freezer and put in the cake—a sheet cake with my son's name in red and black frosting—the colors of the University of UGA, where Laughlin, my youngest, would graduate in May.
But now there would be no graduation because of the pandemic (流行病). I had been looking forward to Laughlin's graduation. I'm a UGA graduate, too, but I didn't attend my graduation ceremony because I received an Army commission (任命) as an air defense officer.
“No graduation!” I said, a bit annoyed that my son, finishing coursework at home, didn't seem bothered. “I need to focus on my classes and get a job, Mom,” he said. But Laughlin didn't know what he was missing. Years later, I still regretted skipping my UGA ceremony. I'd been planning the celebrations for Laughlin since January.
Every day the pandemic worsened. Then, one day, Laughlin's diploma arrived in a black-and-red tube by mail. I pulled the cake out of the freezer and served it halfheartedly. Laughlin found a job and moved to Atlanta to live alone.
One fall evening, a student called from the UGA. “Did your son participate in the graduation ceremony last week?” the young man asked. “What ceremony?” I screamed. “The one at the stadium,” the student said. “To make up for the cancellation in spring.”
I dialed the office of the dean of student affairs. “Why wasn't I notified?” “Mrs. Smith, we sent an announcement to your son's school email,” said the woman who took my call.
I called up Laughlin. “Why didn't you call me?” I asked. “Mom, I did hear about the ceremony and I knew you'd make me go, so I didn't say anything. Why would I risk my family's life for a ceremony? You and Dad are in a vulnerable age group. No way would I do that.”
Laughlin's diploma rested beside the phone. I felt tears in my eyes.
4. Why did the author expect her son's graduation ceremony so much?A.To show off her son's excellence. | B.To pay a visit to the university once more. |
C.To deliver a speech at the graduation ceremony. | D.To make up for her own missing graduation ceremony. |
A.Her son would miss a good job. | B.Her son would regret in the future. |
C.Her son would skip the classes. | D.Her son would move to another city. |
A.Humorous and honest. | B.Energetic and courageous. |
C.Independent and caring. | D.Responsible and sensitive. |
A.Mrs. Smith was moved by her son's words. |
B.Mrs. Smith was excited to see Laughlin's diploma at first. |
C.Mrs. Smith abandoned her graduation ceremony sadly. |
D.Mrs. Smith gave up holding the graduation party. |
Many parents of elementary and middle school students are wondering if they should send off their kids with a phone.
“What we know is that there is not a magic age for when to get a child a smartphone, but by age 11, 53% of the kids have their own smartphone,” said Kelly Mendoza, a vice president at Common Sense Media, a nonprofit group focusing on responsible media use. The figure comes from a 2019 survey the organization conducted of more than 1,600 people between the ages of 8 and 18 in the US. “Sixth grade is a big transition for kids, when they start middle school and start to have more independence,” she said.
Even though middle school is a turning point for many parents in making the leap, Ms. Mendoza said age isn’t as important as a child’s maturity. She said parents can assess their children’s phone readiness by asking themselves the following questions: Do they show a sense of responsibility? Are they responsible for their things? Would they be able to resist texting or scrolling in class?
It is also wise to assess whether there are legitimate needs for children to have a smartphone, such as being able to communicate while taking public transportation, or being reminded to take medication.
Many kids start asking for a phone once their friends have one. The requests can start as early as elementary school, but the peer pressure heats up in middle school.
Understanding your children's motivation can help you decide. Do they just want one because they want to fit in? Are they being excluded from social interactions, such as group texts?
Before they power a phone up for the first time, experts say you should talk to them about your expectations for its use, and the consequences for losing or damaging the phone or for violating school rules, which include when and where the phone should be used, where it should be charged up at night, how to treat others on social media and how to report cyberbullying.
8. Which of the following may Kelly Mendoza agree with?A.It doesn't matter when parents get their children a phone. |
B.When to get children a phone depends more on maturity than age. |
C.Parents should give their children a phone when they are eleven. |
D.Middle school students should have a phone of their own. |
A.Flexible. | B.Ambiguous. | C.Reasonable. | D.Adorable. |
A.Children's purpose. | B.The survey's figure. |
C.Parents' expectations. | D.Schools' special rules. |
A.Kids should have higher expectations for the phone uses. |
B.Parents should inform their kids they should use phones properly. |
C.Kids should follow the rules in case they lose or damage their phones. |
D.Parents should guide their kids on how to power a phone up for the first time. |
University of Minnesota Twin Cities College of Science and Engineering researchers have invented a cheaper, safer, and simpler technology that will allow a “stubborn” group of metals and metal oxides to be made into thin films used in many electronics, computer components, and other applications. The researchers applied for a patent for the technology and have already gained interests from industry.
Many metals and their compounds must be made into thin films before they can be used in technological products like electronics. “Stubborn” metals are very difficult to convert into thin films because they require extremely high temperatures (usually more than 2, 000 degrees Celsius) to evaporate (蒸发). Typically, scientists combine these metal films using techniques like sputtering and electron beam evaporation (溅射和电子束蒸发). The latter consists of melting and evaporating metals at high temperatures and allowing a film to form on the top. But, this conventional method is very expensive, uses a lot of energy, and may also be unsafe due to the high voltage used.
Now, University of Minnesota researchers have developed a way to evaporate these metals at significantly lower temperatures, fewer than 200 degrees Celsius instead of several thousands. By designing and adding organic ligands (配体)—combinations of carbon, hydrogen, and oxygen atoms—to the metals, the researchers were able to substantially increase the materials' vapor pressures, making them easier to evaporate at lower temperatures. Not only is their new technique simpler, but it also makes higher quality materials that are easily expanding.
“The ability to make new materials with ease and control is essential to transition into a new era of energy economy,” said Bharat Jalan, the senior author of the study. “There is already a historical link between the innovation (革新) in synthesis science and the development of new technology. Millions of dollars go into making materials for various applications. Now, we've come up with a simpler and cheaper technology that enables better materials with atomic accuracy.”
These metals are used to make many products, from semiconductors for computer applications to display technology. We hope to see renewed interest in the more complex materials which contain these stubborn metals.
