Summer time is a great opportunity for kids to learn how to work and earn a little bit of spending money. If your child needs a summer job, here are a few options to consider:

Lemonade/Cookie Stand

Benefits

    Creates a concept of running a business: Your child will be his own boss, set his own price , and run the show. It's a great introduction to running his own business.

    Limited Start-Up Costs: The things used to make lemonade are cheap, so your child should be able to get back his investment with a handful of sales.

    What Kids Learn About Money: Your child will learn a very valuable lesson about pricing. The price of his lemonade will decide how much he can sell, if he will recover his investment and the amount of profit.

Yard Work

Benefits:

    Repeated Customers: If a homeowner needs help raking (耙地) this year, he'll probably want help again next year. Your child should be able to maintain a regular set of customers after one season.

    Safety: Yard work is generally safer than a lawn-mowing job. Without having to operate machines, your child will be much safer.

    What Kids Learn About Money: Because of the variability (变动) in pay, your child will need to learn how to negotiate(谈判) a fair price with homeowners if they ask.

Lifeguard

Benefits:

    Responsibility: Kids learn a lot about responsibility when lifeguarding. They are within rights to tell whether a certain activity is safe and are allowed to take action as they see fit.

    Exercise: Lifeguards need to be proficient at swimming and must exercise to stay in shape.

    What Kids Learn About Money: To be a lifeguard, one must be certified. Your child may have to pay for lifeguard training, although some employers provide it on-site.

    A new study suggests that people who drank a certain amount of alcohol（酒）had a lower risk of cancer and death than those who drank more or none during a nine-year period. And with each additional drink a week, the risk of cancer and death from any cause increased, the scientists reported.

    However, the study found only an association between alcohol and cancer and death, and did not prove cause and effect, the researches said. What sets the new study apart, said lead study author Andrew Kunzmann, is that previous studies looked at cancer and death separately. “What our study does is combine the two outcomes together and we find that lighter drinking is associated with the lowest risk of cancer or death,” Kunzmann said.

    But Kunzmann noted that the participants（参与者）were all older adults. That means that “we're not really showing what happens in younger people if they drink,” he said. Also, it's difficult to account for other lifestyles that could have affected the results. “These could also influence health. But the results did take into consideration differences in diet, smoking and education among participants,” Kunzmann noted.

    The researchers said that they hope their study sparks conversation about reducing the suggested alcohol intake in countries' guidelines. “We're not telling people what they can or can't do or what they can or can't drink,” Kunzmann said. “We're just trying to give them reliable evidence so that they can make their own informed, healthy decisions.”

    More than 40 percent of the species that help with pollination (植物传粉) are under threat due to the polluted environment. So some researchers have been searching for ways to protect the bees and other crucial pollinators while some engineers have thought perhaps an army of robotic pollinators could keep humans well-supplied in these foods. A team of researchers has recently designed a small drone capable of pollinating flowers. They tested their device on the large, pink flowers of lilies. And it worked.

    Exciting as this success was, it is only the first step. The team has yet to figure out how to apply the concept on the massive scale. Could a fleet of robo-pollinators replace the bees?

    “Although the answer isn't a straightforward no, it would be a challenging leap to go from this one little drone pollinating one large flower to an army of drones spreading across fields of crops,” says Scott Swinton, an agricultural economist at Michigan State University.

    “The successful pollination was fascinating,” Scott Swinton says, “but the device itself might damage the flowers. I wonder how you make sure you're not doing more harm than good to flowers when you have a drone.”

    “Furthermore,” he points out, “a lily is a particularly easy flower for a drone to pollinate. To make this more broadly applicable for smaller and more complex flower structures, the drones would need to be particularly agile.”

    Still, Joshua Campbell, an expert at the University of Florida, says “Pollination systems are extremely complex and will always require insects. There is no substitute for bees.”

    “As for the technology itself, it is a promising new development in existing drone technology,” he added. Yet he still sees some hurdles ahead before drones can be applied on a large scale.

    Your next car could have two seats, three wheels—two in front and one in the back and a top speed of more than 100 miles per hour. Elio Motors plans to make such a tiny car named the Elio. Its two seats sit front and back instead of side by side. The driver is positioned in the center with the passenger directly behind.

    The starting price for the car is just $6,800. It has only one door, on the left side, which cuts a few hundred dollars off the manufacturing costs. Having three wheels also makes it cheaper. It has air conditioning, power windows and door locks and an AM/FM radio. More features can be ordered through Elio's long list of suppliers. Elio will also sell the cars directly through its own stores and not through franchised dealers (特约经销商).

    Paul Elio dreamed as a kid that he would one day own a car company called Elio Motors. In 2008, tired of high gas prices, he started working on a car that burns gas in a more effective way. Equally important to him was creating US manufacturing jobs and making the car inexpensive enough to attract buyers who might otherwise be stuck in their old, unreliable cars. "Whatever matters to you, this can move the needle on it, he said.

    Already, more than 27,000 people have reserved one. Paul hopes to make 250,000 cars a year by 2020. So far, reservation holders are those who will use the Elio as a second or third car for work. Paul Elio believes the car will interest college students as well as used-car drivers who want something newer and more reliable, though.

    Feel nervous on the first day of school? You are not alone! Here is some advice on how to make you feel comfortable.

    Get ready the night before. Plan out what you're going to wear and what you will need for class. Then get a nice, long sleep. There's nothing worse than looking terrible on the first day of school. If you don't want to oversleep, set an alarm on your phone, or alarm clock to wake you up on time.

    Eat a good breakfast. You'd be surprised at how much happier and more focused you'll be after eating a good breakfast. Have a healthy breakfast. A rich breakfast may make you feel lazy and sugar rich foods may affect your ability to stay focused.

    Decide whether to take the bus, walk, or have a ride from your parents. It's your call. If you want something familiar, take a bus ride and sit next to someone you already know. However, if you are really nervous, you can ask your mom or dad to drive you to school, but expect that there will be heavy traffic.

    Smile and be friendly! You want to seem easy to get along with and that you had the best summer. Smile and be friendly. Instead of coming up as a boring person, compliment people. Everyone needs a little confidence and is happy when praised on the first day of school.
