Scientists are beginning to understand that sitting down for long hours can be very bad for your health. One of the reasons for this is that poor posture (姿势) leads 【小题1】health problems. Here are some suggestions to help improve your posture and your health.

Sitting with poor posture can bring about serious back pain that doesn't go away. Many people believe that they should sit with their backs straight at a 90 degree angle to the floor, 【小题2】scientists have recently discovered that this actually causes more stress on the body. They find that sitting with the back slightly reclined (斜倚) at a 135 degree angle is the 【小题3】(healthy) posture, where the back muscles are relaxed and the spine (脊柱) is at 【小题4】natural resting position.

Many people bend their necks forward to look at a screen or read a book while sitting, 【小题5】develops constant neck pain. The lower neck muscles need to work very hard to support the 【小题6】(weigh) of the head. The bones in the spine can slide forward, 【小题7】 (cause) a great deal of neck pain.【小题8】 (avoid) this problem, you should try to look at the top part of a computer screen when working at a desk. Your elbows should be at the side and your feet should be flat on the floor.

You should also try to 【小题9】(regular) stop work and do some exercises. Put your hands behind your back and bring your chest forward slowly. Take a deep breath and relax. Finally, you can try to buy a special kind of chair that 【小题10】(make)to improve sitting posture.

Sometimes it【小题1】(take) specially designed methods and approaches to let kids learn things which might not naturally come to them. Likewise, the first step in teaching a kid to play football is letting her become familiar【小题2】the ball. Trainers at kid football classes question them“【小题3】(repeat) ” What do we use in football?“ and kids answer ”Feet“.

Next, they should【小题4】(allow) to become confident with the ball. For this, you ask her to keep the ball under one foot and then do it with【小题5】other one. Subsequently, you gently roll it forwards and backwards by supporting the kid’s foot on it. It lets her know that she can control the ball without hands.

Progressing gently, you can start showing the【小题6】(difference) paths the foot can follow to stop and control the ball. You roll the ball towards her and let her control the ball. Followed by this comes the fun part,【小题7】you teach your kid to kick the ball properly. Teach her to kick with the top of the foot with the laces part and not let her get stuck at【小题8】(kick) by the toe-end.

After having her equipped with these basics, you can continue gradually teaching【小题9】(she) dribbling (带球), some trickery and advanced football skills. I takes a lot of【小题10】(patient) and time, but eventually, the joy the kid will find in the sport is worth all of it.

If you make a career choice while you are still in high school, you will save time and money in the long run. Students who do not plan ahead may delay starting college or take extra courses 【小题1】(give) themselves time to make up their 【小题2】(mind). U.S. News and World Reports 【小题3】(say) that the average annual tuition at a four-year college is $ 35,000. If you spend 【小题4】 extra year in school, you may have to take out additional loans or pay extra money to cover the cost.

Choosing a career while you are in high school also gives you time to explore your 【小题5】(choose) industry. If you find a career 【小题6】 sounds interesting, you can follow someone in the field and see what it is 【小题7】(real) like to have that job. You can also apply 【小题8】 a chance to get an informal position related to your desired industry. This will help you build a professional network even before you graduate from high school. Professional contacts are very 【小题9】(value), especially when you are looking for a job in your field. If you do as much as you can to build a network 【小题10】 you are ready for a job, you will be more likely to succeed.
