“Human influenza viruses can survive and be infectious for several days when they are deposited on banknotes,” according to the latest study by Yves Thomas and his colleages in Switzerland. Scientists put different types of flu virus onto Swiss franc notes and found that they could survive from a few hours to more than a week. The results depended on the type of flu virus.
According to the study, Swiss-banknotes are mostly cotton covered by a nonporous resin(无孔树脂). Banknotes from other countries may be composed of different materials, and this could affect viral transmission. “Whether similar results would be obtained with banknotes from other countries and with different characteristics needs to be studied.” the authors wrote. In an interview with Reuters, Thomas said. “Our studies have convinced us that it is possible to catch the flu from banknotes, but the chances are very, very small and there is no cause for concern among the gneral population,” To be sure, many kinds of frequently touched surfaces could temporarily hide the flu virus. Broadly speaking, scientists consider the risk of transmission in this way to be low. Particularly if hand-washing and other hygiene measures are practiced.
Three things must happen for a flu virus to be transmitted from one person to another via money. First, a person who is infected with the flu virus must sneeze or cough onto the banknote. Next, an uninfected person would need to touch the money while the virus si still present. Finally, that person would need to put his hand in his mouth or pick his nose, says Thomas. The best defense against infection: follow public health guidelines and wash your hands frequently.

As a parent you have the responsibility to help your children understand money. But first you will need to understand your own attitude towards money, and make sure to practise what you teach.
Ask yourself what things that cost money are the most important to you. Also ask yourself what financial goals do you have for yourself and your family this year, in five years, and so on?
Take a minute to write down a list. Below are some ideas to get you started. There’s no right or wrong here. This exercise is just to help you grasp what money means to you so that you can help your children understand your values.
◆ Home
◆ Household expenses
◆ Education
◆ Recreation, entertainment
◆ Savings
◆ Charitable contributions
You can start discussing money when your children are as young as three years old. The best time to teach a child anything is when he or she shows an interest. So he prepared to start talking about money when your child starts asking you to buy candy or toys.
Begin by showing how money is exchanged for items or services. Show your children how money works by allowing them to buy something, such as a toy or a book.
Be open and honest, and explain to your children why they can or cannot have certain items. If you must say no to a child’s request to spend money, you might say, “You have enough toy trucks now.” Or, if the request is for multiple items, “You have a choice to make, between this toy and that one.”
You can start explaining the bigger picture once your children understand the basic function of money. Show an older child how money is used to provide for the whole family.

Shelly Nielsen sees students fall asleep in class at least twice a week. “When I see teens asleep in my class, I wonder if I am really that boring”, said Nielsen, a teacher. “I also wonder why they are so tired.” Neilson first tried to wake up sleeping students quietly. If the snoozing (呼噜声) continues, she may call a student’s parents to find out how much sleep the students is getting at night and why.
According to a research, teens need at least nine hours of sleep to function properly during the day. And more than 90 percent of teens say they are sleeping less than that each night.
Forgetting homework, yawning in class, losing concentration --- these are the signs of a sleep-deprived (被剥夺睡眠的)student, said Dr. Carl Lawyer, a specialist. “The big problem is the social demand for homework, video games and friends. Teens don’t understand how important sleep is.”
Rebecca Lucas, another teacher agrees. “Teens are busy,” she said, noting many activities most teens are involved in during the day force them to get home pretty late.” When I see teens sleeping in my class, I feel sad, like they are not sleeping enough,” she said. “I also feel frustrated because I have so much to teach in such a short amount of time and teens sleeping in the class slows me down.”
Not sleeping the needed number of hours can affect your day very much. The effect is on school, work and driving and is very frustrating to teachers when students don’t do their best because of being so tired, Lawyer said.
Al Taylor, a teacher says sleeping is not allowed in his class. “When I see a teen sleeping in my class, I feel bad that they didn’t get enough sleep but they need to correct the issue at home,” Taylor said. “I’ve raised teenage boys myself. Teenagers like to wait to the last minute to do their homework so they often stay up late trying to finish it.”

Everyone knows the story of Benjamin Franklin’s famous kite flight. He was a man of many talents and interests. His natural curiosity about things and the way they work made him try to find ways to make them work better. Although he made important discoveries and advancements, Ben didn’t “invent” electricity. He did, however, invent the lightning rod which protected buildings and ships from lightning damage.
In colonial America, most people warmed their homes by building a fire in a fireplace even though it was kind of dangerous and used a lot of wood. Ben figured that there had to be a better way. His invention of an iron furnace stove allowed people to warm their home less dangerously and with less wood. The furnace stove that he invented is called a Franklin stove. Interestingly, Ben also established the first fire company and the first fire insurance company in order to help people live more safely.
As the postmaster, Ben had to figure out routes for delivering the mail. He went out riding in his carriage to measure the routes and needed a way to keep track of the distance. He invented a simple odometer and attached it to his carriage.
In his old age, Ben retired from business and public service and wanted to spend his time reading and studying. He found, however, that his old age had made it difficult for him to reach books from the high shelves. Even though he had many grandchildren to help him, he invented a tool called a long arm to reach the high books. The long arm was a long wooden pole with a grasping claw at the end.
Later, other famous inventors, like Thomas A. Edison and Alexander Graham Bell, would follow in Ben’s footsteps by trying to find ways to help people live better. Today’s curious thinkers are keeping Ben’s traditions alive by inventing new and improved ways to make things work.
