Experts in childhood nutrition aren’t surprised by an investigation this summer that shows 50％of parents who have overweight children don’t realize their children Weigh too much．Many parents deny their children’s weight because they don’t want to have to change their own eating and exercise habits，says Keith Ayoob, a doctor who works with overweight children and their families in New York City．
Parents frequently ask him whether their children have a thyroid(甲状腺)problem, but that’s rarely the case．“1t’s usually a dietary(有关饮食的)and lifestyle issue．It’s very difficult for parents to deal with their own food issues，”Ayoob says．An estimated 25 million children in the USA are overweight, which puts them at risk of developing diabetes(糖尿病), high blood Pressure and other health problems．A Consumer Reports magazine investigation released on July 25，2009 of 3．048 parents who have children aged 5 to 17 found that 91％ say childhood obesity(肥胖)is a problem in the USA．
Only 36％of the parents with heavy children say their family doctors have suggested their children lose weight；the other 64％say the doctors didn’t mention it．“Many parents simply don’t realize their children are overweight．”says Keith Ayoob．“The doctors never told them．Other kids in the class look like their children．and their kids seem pretty healthy．”he says．
He has parents go to the calculator on the Centers for Disease Control and Prevention website to figure out whether their children are too heavy．

Why is it easy for young children to learn language?Part of the answer is that children have so many needs．They have to make their needs known and they are always watching the effect of what they say and trying new ways of getting what they want．Another part of the answer is that children are not, as older people sometimes are, fixed in their ways of living．When they are taken about from one country to another they change easily from one language to another．Older people are more fixed in the ways．They have been hearing and talking one language for a long time．Their ways of hearing and making sounds and of putting words together are like the rails a train goes on．They have been up and down their lines of talk and thought too many times to change them easily．A child is free in his ways．He is more like an airplane or, better, like a bird; he is free to go in any direction he wants．He is free to hear sounds as they are and make them as he hears them．He is free to put new words together in new ways in speaking a new language．

Why Rent Textbooks?
Renting textbooks is a relatively new idea for everyone．Back in the old days, the idea of renting one never existed since the books are affordable or readily available in libraries．But the time has changed and with the changes in educational system and various economic challenges happening across the globe, the price of textbooks increased．
Given such fact, textbook renting is now a new fashion among college students．Research was made to find out if renting helps one save money and time rather than buying new textbooks and realized that it really is．Let's examine carefully further and see why renting books is a cost-effective way to still get to have your textbooks without shelling too much money from your pocket．
Gives value for your money
You don't have to buy all of your textbooks．Those non-major subjects, are better acquired through renting．It saves one money and helps you give out the money you save on some other personal possessions you need in college．
Renting textbooks allows you to save at least 50％ off the standard retail(零售)price for each item．You can tell, with a little research, that renting is a lot cheaper compared to buying used books aside from looking way better than the former．
Saves time
You can save a great deal of time when renting a textbook．Instead of browsing your way for hours trying to look for better deals online, you can simply go to a popular book renting marketplace online and just order away．There is literally no need to skimming for hours and see where you can find a great deal．Often, the rental company gives you prepaid postage slip just to get you going and do the same when you decide to return the book．
This process not only saves you time, it also saves other resources like gas if you decide to go to the nearest bookstore to buy books or spend hours using electricity just to find a good deal．
User Friendly
Aside from being able to save money and time, renting textbooks brings convenience to all users．Imagine trying to scan the virtual bookshelf and checking on comments of previous users and figuring out which ones got bad comments and which had great ones．It could be fun at first but if you are short of time, the process can become annoying．
If you rent books, you will only be needing the book's ISBN number and find it right away．No more time-wasting site search．Type in the ISBN number, order the book, and wait for it to get shipped to your home．
