Djokovic has now equalled the record of Roy Emerson winning six Australian Opens. Djokovic after the match said,“Andy, you are a great champion and friend. I'm sure you'll have more opportunities to fight for this trophy”.Murray congratulated Djokovic, saying “I feel like I've been here before. Congratulations, Novak. Six Australian Opens is an incredible feat (业绩).The last year has been incredible. Good job.” He also left a message for his wife Kim Sears,“I'll be on the next flight home.” The couple is expecting a baby.
Yesterday, Jamie Murray, Andy Murray's elder brother, won the Australian Open Men's doubles with Bruno Soares. Andy Murray was there in the audience, recording his brother's speech, to which Jamie said,“Andy, you should be in bed!”
People love cellphones, which is why nine in ten Americans own one. But does heavy use of cellphones pose a risk of cancer? This question has caused controversy for many years. A new study in rats now augments those concerns. Its data linked long-term, intense exposure to radiation from cellphones with an increased risk of cancer in the heart or brain. The results have yet to be confirmed, the authors note.
Indeed, although the rat study found a link between cellphone radiation and cancer, it offers no clues to why such a link might exist, notes Jonathan Samet. He teaches preventative medicine and directs the Institute for Global Health at the University of Southern California in Los Angeles. Still, he calls the new study's findings “significant”.They could lead to studies researching how cellphone radiation might cause cancer, he says.
Phone signals are relayed between cell towers and cellphones via radio waves. This radio frequency—or RF—radiation is a type known as non-ionizing (非电离的).Unlike X-rays, non-ionizing radiation does not deposit enough energy into cells to release electrons from atoms or molecules, producing ions. So it tends to be far less harmful than ionizing radiation, such as X-rays. But that does not mean radio waves might not cause harm.
In very large doses (量) this radiation will heat the body and cause tissue damage. But it's not yet known what much lower RF levels might do, such as those from cellphone use. Five years ago, the World Health Organization's International Agency for Research on Cancer, or IARC, concluded that cellphone use “is possibly carcinogenic (致癌的)”.
Its conclusion was based on what little research data was available at that time. But notice that IARC was not certain. It said only that phone use might “possibly” cause cancer. So scientists at the National Toxicology Program, or NTP, investigated further.
Teens naturally ask parents for money for material things and entertainment. But as the need becomes more frequent, why not get a job so you can earn your own money? Working for your own money will give you a sense of accomplishment and the satisfaction of a job well done.
Babysitting is a suitable job for teens. They are best suited as a mother's helper while the mother is working in another part of the house. Babysitting is not a job for girls alone. Boy babysitters are popular with families of boys. Parents rely on friends and neighbors' recommendations. Word of mouth is your best form of advertising.
Pet-sitting involves caring for people's pets while the owners are on vacation or away for the day. A pet-sitter will be responsible for giving fresh food and water, walking dogs and cleaning out cat litter boxes. Although the pet-sitter does not spend the night, he is there often enough to bring in the mail, water plants and take the garbage out. Create a flyer with your name, prices and references, and pass it out to the families in your neighborhood.
Yard work can be a seasonal job. Spring cleanup is needed for flower beds and preparing the yard for summer. Summer is the busiest time for yard work with lawn mowing (割草坪),edging and trimming(修剪) bushes. Fall is the time for sweeping leaves and planting seeds for spring. If you live in a northern climate, there may be snow that needs shoveling.
Odd jobs can mean a variety of things, including painting, washing the pet, weeding the garden, cleaning out the basement, or helping to serve dinner at a party. Doing odd jobs may be a good match for someone with a busy schedule. Most odd jobs only take a few hours to complete.

Lots of people find it hard to get up in the morning, and put the blame on the alarm clock. In fact, the key to easy morning wake-up lies in resetting your body clock. Here's how to make one.
● In order to make a change, you need to decide why it's important. Do you want to get up in time to have breakfast with your family, get in some exercise, or just be better prepared for your day? Once you are clear about your reasons, tell your family or roommates about the change you want to make.
●Rethink mornings. Now that you know why you want to wake up, consider re-arranging your morning activities. If you want time to have breakfast with your family, save some time the night before by setting out clothes, shoes, and bags. That's a quarter-hour more you could be sleeping if you bought a coffee maker with a timer.
●Keep your sleep/wake schedule on weekends. If you're tired out by Friday night, sleeping in on Saturday could sound wonderful. But compensating on the weekends actually feeds into your sleepiness the following week, a recent study found.
●Keep a record and evaluate it weekly. Keep track of your efforts and write down how you feel. After you've tried a new method for a week, take a look at your record. If not, take another look at other methods you could try.
A. Get a sleep specialist.
B. Find the right motivation.
C. A better plan for sleep can help.
D. And consider setting a second alarm.
E. If the steps you take are working, keep it up.
F. Stick to your set bedtime and wake-up time, no matter the day.
G. Reconsider the 15 minutes you spend in line at the cafe to get coffee.
Last December, just a week before Christmas, I went to a local KMart store to pick up my layaway (预付定金购物).Upon reaching the counter, I 1the clerk my layaway receipts and told her I was there to pay off the balance and take the 2home with me. She grabbed my receipts, and kept messing with the computer 3something was wrong. I felt a little uneasy. I was4 her to tell me my layaway had been misplaced or something of the sort.
5, after about ten minutes, she said,"Oh, that's why I can't find it in our 6. You should have 7a phone call a few days ago that your layaway was paid off by a(n) 8 Santa."I couldn't believe what I was hearing! This kind of story only happens in the 9.Why was my family 10 to receive such a blessing?
Immediately I asked the cashier if there was a 11 that I could leave something for the Santa 12 his random act of kindness, but she said that the individual wanted to 13 completely unknown. It definitely 14 my heart. However, I felt kind of 15. I kept thinking that perhaps some family out there was not going to have a Christmas because they really couldn't 16 to pick up their layaway.
I decided to pay it17, so I used the money I had for the balance on my account to purchase some 18 and on my way out, I gladly 19 them off inside a huge toy donation box. Since I had received such a nice, heart warming gesture from someone, I wanted to keep the 20 going. And it felt nice to receive and to be able to give right back.
One day, I was walking in the street when I noticed a woman (come) up to me with a nervous smile and said,“Sir, can you help a person out? I haven't eaten for almost two days.” I handed (she) a few quarters and watched her walk away.
That area was so poor and (rule) by drugs and crimes. I walked to the corner and stopped by the door of the ATM machine. Then I (walk) inside and made sure that no one came in behind me.
I put my card into the machine and deposited my money with a sigh of relief.60. I turned to leave, I saw a wallet sitting on another machine. I had a look at it. The name on the license was one I could not pronounce, but whoever he was, he was going to get into a panic over a wallet his identification in it being lost in this city.
I put it in my pocket and went home. In my apartment, I checked the online phone book (find) out whether there was someone who matched the name on the cards in the wallet, but without luck. I picked up the bank card and had thought. Because I wanted to help the guy, I called his bank. But the girl over the phone said they could not give out any personal information about their clients. So I left my contact information with her and asked her to tell the (own) to contact me. Two days later, a very (thank) gentleman appeared at my office and I gave him back his wallet.
According to most people, after a long period of studying or working, we need to have a rest to refresh ourselves. However, that may not be the case. According to a recent report, you don't need the break as much as you may think that makes you feel less tired.
Scientists have long assumed that willpower is a limited resource, which is why you feel the need to have a rest, have a snack and then get back to the task when you are feeling better. They argue that the only way it restores willpower is by rest, food or entertainment.
But psychologists have challenged this theory, saying weak willpower is all in your head. They have found that people's belief in willpower determines how long and how well they'll be able to work on tough mental exercise.“If you think of willpower as something that is not really used up, you can go on and on,” said Professor Veronika Job.
The researchers designed four experiments to test students' belief in willpower. After a tiring task, those who believed, or were led to believe that willpower is a limited resource, performed worse on standard concentration tests than those who thought of willpower as something they had more control over. They also found that leading up to the final exam week, students who believed the limited resource theory ate junk food 24 percent more often than those who believed they had more control in resisting the temptation.
Mr. Job said,“The theory that willpower is a limited resource is interesting. Belief in willpower as a non-limited resource makes people stronger in their ability to work through challenges.”
The findings can help people who are battling against temptation. Willpower isn't driven by a biologically-based process as much as we used to think. The belief in it is what influences your behaviors.
