On June 15th，2012，millions of people watched as 33yearold Nik Wallenda walked across one of the world's greatest waterfalls on a tightrope（钢丝）．What made the 25－minute walk that was televised live and watched by over 13 million people worldwide even more amazing，is that it was done over the Niagara Falls－An action that had never been attempted before．
Even though Nik was wearing a harness（保护带），a safety measure provided by ABC，the television network that broadcast the event，his action to keep his balance against the strong winds made for some heart－stopping（令人担忧的） moments for the audience．
Nik，however，never slowed down for even one moment．Wearing special shoes made by his mother，he remained totally focused on the job at hand．It was only when he got to the last stretch near Canada's Table Rock that he knelt down on one knee and finally broke into a smile．Waving and blowing kisses to the cheering audience，he knew he had accomplished a great task，which most people had thought impossible．
While he described the whole experience as peaceful and relaxing，Nik said his biggest challenges came from a totally unexpected source－his 40 pound balancing pole．The balancing pole was so heavy that he could hardly carry it on the tightrope．
One would think that now that Nik has realized his lifelong dream he would be ready to hang up his “balancing pole”．However，the adventurer who already has seven Guinness World Records under his belt，is just getting started－Next up? A 5，000－foot tightrope walk across the Grand Canyon．While the one across the Niagara Falls took years of planning because he had to convince the US and Canadian officials，this one should happen in the very near future．That's because，the Florida resident has already been granted（授予） a permit by the Canyon officials．Why did so many people fix their attention on the event?
A．Because it was done by Nik Wallenda．
B．Because nobody had done it there before．
C．Because it was broadcast live by ABC．

What was the greatest difficulty for him to face in Nik view?

One of the most wonderful things about having a positive attitude is that it can touch many people, and it often exists in our everyday life.
Recently, I stopped by a store to get a newspaper and a bottle of drink. The young woman at the check-out counter said, “That’ll be three dollars in all please.” She then glanced down at the paper I was buying and said. “I’m sick and tired of all this negative stuff-on the front pages. I want to read some good news for a change.” She then said, “In fact, I think soemone should just publish a Good News newspaper--- a paper with wonderful, inspirational stories about people over-coming difficulty and doing good things for others. I’d buy one every day!” she then thanked me for coming in and said, “Maybe we’ll get lucky tomorrow; maybe we’ll get some good news.” And she laughed. She made my day.
The following day after my business appointments. I dropped by the same store again to pick up bottled water and a piece of newspaper, but a different young lady was behind the counter. As I checked out I said “Good afternoon” and handed her my money. She said nothing, not a word, not a smile or not a gesture. She just handed me my change and in a negative tone ordered “Next!”
It hit me right between the eyes: Two people, the same age; one made me feel great, and the other, well, made me feel that I had inconvenienced her by showing up.

“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.

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.”
