Best Summer Jobs for High School Students
Working during the summer when school is out of session is a great opportunity for teenagers to make money and gain valuable workplace experience.
Restaurant Server
Food and drink service jobs are plentiful. Although average base pay is poor, workers who carts tips can do well for themselves. And some national chains have the resources to pay more Starbucks employees can earn about $12 per how on average, and may qualify for a benefits package that includes health insurance.
Grocery Store Worker
Grocery store jobs are also relatively plentiful. Although most grocery employees don't earn tips, base pay is generally above the federal minimum wage—about $12 per hour. Jobs that require workers to operate heavy machinery are inaccessible to workers under age 18. Grocery store employees typically work in shifts, with part-timers polling four to eight hours at a stretch. Peak shopping hours tend to fall on weekends and early evenings.
Tutor
If you've already taken and done well on standardized tests like the SAT or ACT, you can help these students and earn decent pay as a tutor. Tutor pay varies by specialty, experience, and educational attainment. Tutors who themselves are high school students or recent graduates aren't likely to earn much more than the national average rate of S18 per hour.
Career-Track Intern(实习)
Even if you haven't yet decided what you want your "rear" career to be, high school summers offer the perfect opportunity to test a job you think you'll like. Summer internships are often unpaid, forcing students to consider whether the opportunity is worth the cost. That's likely to come down to the value of the experience and the connections that could land you a higher-paying, career-track job down the road.
Heroes Monica and Bryan Davies had only just trained as couriers (递送员) for the charity Anthony Nolan when the coronavirus broke out. But they were determined to volunteer to deliver stem cells to cancer patients, inspired by their daughter Helen's brave battle with her illness and meeting the selfless stem cell donor who came to her rescue.
Monica, 67, said: "I couldn't bear the thought that other families standing by a hospital bed, being told the transplant couldn't go ahead because the stem cells couldn't get through."
Helen was diagnosed (诊断) with Hodgkins Lymphoma in 2010. The diagnosis was all the more terrifying as a close family friend had lost their teenage son to the disease a decade earlier, but at first the doctors comforted Helen and said she was likely to make a full recovery.
The doctors said Helen's age and fitness worked in her favour. They said she would have six months of treatment and she would be fine. But within months of finishing her treatment, Helen's cough returned and scans revealed a shadow on her chest. Further investigations confirmed the cancer was back.
The doctors used up all treatments except a stem cell transplant from a donor. Thankfully a matching donor was found on the Anthony Nolan stem cell register and Helen had her transplant in March 2014. This time Helen made a good recovery. She wanted to contact her donor, but strict anonymity (匿名) rules prevent patients meeting their donor for two years after the transplant.
As soon as she was allowed, Helen made contact with her donor Ben Potts, from Kent. They quickly became friends and she invited him to her wedding in September 2016.
After that, Monica and Bryan decided to support Anthony Nolan and volunteered to become stem cell couriers when they retired and returned to England.
The couple made three deliveries a week at the peak of the pandemic. They've now covered 15,000 miles. Henny Braund, Anthony Nolan's chief executive said: "Over the last year our volunteer couriers have showed just how committed they are to giving people with blood cancer a second chance of life."
To communicate with others, we, the people, have different languages. But what about other animals and plants? Well, according to a scientist, plants talk to each other using language.
Jim Westwood, a Virginia Tech scientist, made this discovery by looking at the interactions between a parasitic (寄生的) plant called a dodder and two types of host plants, a small flowering plant and a tomato plant. Dodders use a root—like part to enter their host plants and feed on their nutrients.
In previous studies, Westwood had discovered that during this interaction, RNA molecules (分子), which play a crucial role in translating information passed down from DNA, were being passed between the two species.
And recently, Westwood looked into the possibility that a special type of RNA molecules, mRNA or Messenger RNA, were also being exchanged between the parasitic and host plants, mRNA molecules send messages within cells, instructing them on which actions to take and when. Through this exchange, the parasitic plant may be instructing its host to lower its defenses so that the parasitic plant can more easily attack it.
Besides giving us a much deeper insight into the behaviour of plants, this information could help scientists come up with better solutions to fight the parasitic weeds that threaten food crops. Parasitic plants are serious problems for crops that help feed some of the poorest regions in Africa and elsewhere. In addition, it has exciting implications for the design of novel control strategies based on interrupting the mRNA information that the parasite (寄生虫) uses to reprogram the host.
"The beauty of this discovery is that this mRNA could be the Achilles' heel for parasites," Westwood said. "This is all really exciting because there are so many potential implications surrounding this new information. Now that we have found that they are sharing all this information, the next question is, ‘What exactly are they telling each other?'."
The space community is taking the orbital debris (碎片) threat increasingly seriously these days. Multiple satellite "mega-constellations (巨型星座)" are in the works, making space traffic management and space-junk removal more pressing issues than they've ever been.
For instance, SpaceX has already launched more than 1,700 satellites for its Starlink broadband constellation. The company ultimately wants to launch around 30,000 Starlink satellites into orbit. One Web has launched more than half of the satellites for its planned 648-member constellation, which may also grow beyond that initial number as time goes on.
In addition, satellite construction costs continue to fall, allowing more and more people to get satellites up and operate them—including folks with very little experience in the field. This opening of the final frontier is generally a good thing, but it further highlights the need for responsible action when it comes to satellite operation. In 2019, for example, the Space Safety Coalition (SSC) laid out a set of proposed voluntary guidelines designed to control space junk over the coming years.
One recommendation is that all satellites operating above 250 miles be equipped with propulsion(推进) systems, allowing them to get away from possible collisions (碰撞). The SSC also recommends operators who control satellites in low Earth orbit should include in their launch contracts a requirement that rocket upper stages should be got rid of in the atmosphere shortly after liftoff.
More active debris-fighting strategies could also be part of the solution. Removing just a handful of rocket bodies or dead satellites every year could help us keep our space-junk problem under control, according to some studies. And researchers around the world are developing and testing ways to do just that, using nets, harpoons(鱼叉) and other methods.
The space-junk issue is a global one, so governments around the world should have conversations about how to deal with it. Let's hope the talks, the decisions and the tech end up outpacing the problem.
Good health can be defined as physical, mental, and social wellbeing, and as a resource for living a full life. But maintaining good health doesn't happen by accident.
Studies have found that inflammation (炎症) can damage tissue, joints, artery walls, and organs. A healthy diet is rich in fiber, whole grains, fresh fruits and vegetables, good or unsaturated fats, and omega-3 fatty acids. The Mediterranean diet meets all of the criteria for good health, and there is convincing evidence that it is effective at warding off heart attack, stroke, and premature death.
Physical activity is also necessary for good health. There are many benefits to exercising regularly. These include a lower risk of diseases like cancer and diabetes, improved physical function, and a higher quality of life. For example, pregnant women who engage in routine physical activity are less likely to gain a large amount of weight or experience depression after giving birth, elderly people who exercise are at lower risk of being injured during a fall.
Stress can have both direct and indirect effects that undermine physical health and body. Finding ways to reduce stress is another strategy that can help you stay healthy, given the connection between stress and a variety of disorders. Try meditation, mindfulness, yoga, playing on weekends, and taking vacations.
If something happens to your health, a physician you know—and who knows you—is in the best position to help. He or she knows how to deal with everything from helping you through a bout with the flu to back pain and digestion issues, to uncovering serious illnesses like cancer and heart disease.
A. There are many ways to relieve stress.
B. Exercising can also benefit certain groups.
C. Aim for 150 minutes of exercise every week.
D. Have consultations with famous and reliable doctors.
E. These dietary components can turn down inflammation.
F. Establish a good relationship with a primary care physician.
G. It requires work, smart lifestyle choices, and regular checkups.
80-year-old Joao is a great Brazilian classical pianist. At the age of 8, he had already won a contest 1 Bach. He could play 21 notes per second at the 2 of his skills.
However, fortune wasn't 3 to Joao. At 24 years old, he suffered an accident that 4 the nerves in three of his fingers. And at 55, he was struck in the head, leaving him with brain injuries that completely paralyzed (使瘫痪) his 5.
He had to abandon the piano, since he could 6 use his fingers. But paralyzed hands weren't enough to make him 7 his musical career. Joao became a(n) 8 in 2003. He couldn't turn the pages in the score or even swing the stick, so instead, he just committed every score to 9, note by note—almost 5,000 score pages.
Luckily, an engineer who saw him playing live decided to 10 something to help him. After a concert, he 11 Joao with the first model of a pair of special artificial gloves.
After 12 several models, the perfect match was created. The gloves provide the necessary 13 for each finger and can even "tune" to what he plays. After more than 20 years, João could finally 14 with his piano.
João knows that he might never recover his 15 of the past. But he's starting over, and he will keep pushing.
Although picture quality (improve) greatly with the development of flat-screen televisions, sound has taken a dive. The problem is that televisions with slimmed-down screens have insufficient room for decent speakers to be fitted to them, either at the back in the frame (框). Such televisions are usually connected to external sound system, such as a sound bar or a home-cinema system, (make) their audio quality better.
The loudspeakers of early televisions were as big as the screen, but engineers have got good at making speakers smaller and putting them into (tight) spaces. Sony is the first company to develop it calls Acoustic Surface.
Unlike (tradition) ones, this screen gives off the light directly. This means it is able to vibrate (振动) more (flexible). This vibration is invisible to the viewer and does not affect picture quality. One beneficial consequence is that a program's music (broadcast) directly at the viewer instead of from the side. It is also possible to create stereo (立体的) effects by (move) the sound's point of origin across the screen.
Mason followed his mother to the market as usual. It was a thing he enjoyed because the market was such an exciting place. There was always something interesting to see.
That day, Mason caught sight of a middle-aged man with untidy hair and old clothes. He was a beggar. He held out a wooden bowl and passers-by dropped in coins. Mason's mother put a small coin into the bowl as she passed him by. His eyes followed the mother and son as they set off for home.
As Mason and his mother turned into the narrow path that led to their house, he suddenly realized that the beggar was following them. Mason told his mother about it. Alarmed, she quickened her steps and as soon as they got inside their house, she locked it. Mason peered out the window and saw the beggar sitting on the ground near the gate. Why did the beggar follow them? Mason wished he knew.
After a couple of hours, Mason's mother became concerned for the poor beggar. He had not moved from his spot. She gathered up her courage and went to ask the beggar to leave. But the beggar merely looked at her with a gentle smile. Worried that he would fall ill with no food and water, she sent Mason to give him a bowl of rice and vegetables and some tea. The beggar ate and drank. Then he lay down under a tree to sleep.
Mason's mother was at a loss as to what else to do. She was just a poor woman with a young son. Since the beggar refused to leave, she and Mason built a little shelter for him. He seemed content with whatever they gave him.
A week passed and one day, Mason found the beggar gone. Mason and his mother searched for him but he was nowhere to be found. They didn't know what had happened to him.
