Don't you just love ice skating every winter? I am sure, that since winter is approaching, your skates are set to come out, just waiting to be used. Impress your friends with your new trick on how to ice-skate backwards with the help of these tips. Skating backwards on ice is a bit difficult but once you master the basic, there' s nothing like it. Follow the steps given below and you will be able to skate backwards in no time.     

Stand Straight

The first thing that you need to do is, stand straight. If you feel that you are falling backwards, then just put your chin up and slightly bend your knees. Don't worry; this happens to all.

Confidence is What You Need

The most important step while learning how to skate backwards, is having enough confidence in yourself and in what you are doing. How can you achieve this? By practice. Just practice rolling backwards down a gentle slope every single day or just by pushing off from a wall or something of that sort. But before you do that, make sure that the place where you are practicing is free from any kind of debris（碎片）because otherwise, you could end up in the hospital due to some accident. While going backwards, just get used to the feeling of moving backwards. One of the important ice skating tips and techniques is that if you feel that you are losing your balance, then scissor (做剪式运动) your skates. Keep practicing this till you are confident about it.

Maintain Speed

Confident now? Great! Now the next step is to maintain your speed. While rolling in a straight line with one skate, with the other try sculling (滑浆), that is, keep pushing yourself backwards with an outwards stroke (滑动). Now bring the skate which you were using to scull, and then again, repeat the same process. Make sure that you put most of your weight on the skate which is moving straight and not the one with which you are sculling. Now, try the same thing using the other foot. Again keep doing this till you are confident enough.

Increase Your Speed Now

Once you are confident that you can scull with either foot, the next thing that you have to do is increase your speed. Try some of your own tricks now. Scull with either foot or with both at the same time.

Scull and Be Aware

While you keep one foot straight, keep sculling with the other. You can do that simultaneously with both feet. Concentrate on what you are doing but don't get so involved that you don't see where you are going. If you are not watching your back, you might just bang against something or someone.

Fifteen percent of US teenagers aged 12 to 17 who own mobile phones have received nude（裸体）or nearly nude images of someone they know, according to a survey released on Tuesday.

Only four percent of mobile phone-owning   1  in that age group have sent sexually suggestive pictures of themselves, a practice known as "sexting,"   2  the Pew Research Center’s Internet & American Life Project.

The Pew survey found that girls and boys were equally as likely to have sent a suggestive picture to   3 person and  4   teenagers were more likely to have engaged in "sexting."

Eight percent of 17-year-olds with mobile phones have sent a sexually provocative（刺激的） image  5   texting and 30 percent have  6    a nude or nearly nude image on their phone.

Only four percent of 12-year-olds have sent suggestive images of   7  .

Amanda Lenhart, a senior research specialist at Pew and the author of the report, said sexually suggestive images have become a   8   of "relationship currency" for teens.

"These images are    9  as a part of or instead of sexual activity, or as a way of starting or  10  a relationship with a significant other," she said. "And they are also passed  11   to friends for their entertainment value, as a joke or for   12  ."

"The desire for risk-taking and sexual exploration during the teenage years   13   with a constant connection via mobile devices creates a 'perfect storm' for sexting," said Lenhart.

"Teenagers have always grappled with issues around sex and   14   , but their coming-of-age mistakes transgressions have never been so easily   15   and stored for others to see," she added.

The survey found that teens with unlimited text messaging plans were more likely to receive "sexts"   16   images of people they know. About 75 percent of mobile phone owning teens have unlimited plans.

Among this group, Pew said 18 percent reporting receiving "sexts"    17   with eight percent of teens on    18   data plans and three percent of teens who pay per message.

According to Pew, 58 percent of 12-year-olds own a mobile phone and 83 percent teens aged 17   19    .

Pew noted that a number of US states are grappling with how to  20   "sexting" among minors and some legislatures(立法机关) have stepped in to consider laws that would downgrade charges from felonies（重罪） to misdemeanors（轻罪）.

Pew conducted telephone interviews with 800 teens aged 12 to 17 and their parents between June 26 and September 24.

Normally a student must attend a certain number of courses in order to graduate, and each course which he attends gives him a credit which he may count towards a degree. In many American universities the total work for a degree consists of thirty-six courses each lasting for one semester. A typical course consists of three classes per week for fifteen weeks; while attending a university a student will probably attend four or five courses during each semester. Normally a student would expect to take four years attending two semesters each year. It is possible to spread the period of work for the degree over a longer period. It is also possible for a student to move between one university and another during his degree course, though this is not in fact done as a regular practice.

???? For every course that he follows a student is given a grade, which is recorded. and the record is available for the student to show to potential employers.? All this imposes(增加)? a constant pressure and stress of work, but in spite of this some students still find time for great activity in student affairs. Elections to positions in student organizations arouse much enthusiasm. The effective work of maintaining discipline is usually performed by students who advise the academic authorities.
