Parents should ban electronic media during mealtimes and after bedtime as part of a comprehensive “family media use plan”, according to new recommendations from the American Academy of Pediatrics. “Excessive media use is associated with obesity, poor school performance, aggression and lack of sleep”, said Marjorie Hogan, co-author of the new policy.
    Families should have a no-device rule during meals and after bedtime, the guidelines say. Parents should also set family rules covering the use of the Internet, cell phones, including, perhaps, which sites can be visited, and who can be called. The policy also restated the existing recommendations: Kids should limit the amount of screen time for entertainment to less than two hours per day; children younger than 2 shouldn’t have any TV or Internet exposure. Also, televisions and Internet-accessible devices should be kept out of kids’ bedrooms.
    Doctors say parents need to obey the family rules, too, to model healthy behavior. That, some say, may be the toughest part. “If you go to any restaurant, Family 3.0 is Mom and Dad on their devices and the kids on theirs”, says Donald, a pediatrician(小儿科医师) and an AAP spokesman. “Who is talking to each other?”  
    Children aged from 8 to 18 spent an average of 7 hours and 38 minutes a day consuming media for fun, including TV, music, video games and other content in 2009, according to a 2010 report from the Kaiser Family Foundation. The report was based on a survey of 2002 third through twelfth graders, 702 of whom completed a seven-day media use diary. That was up about an hour and 17 minutes a day from five years earlier. About two-thirds of 8 to 18-year-olds said they had no rules on the amount of time they spent watching TV, playing video games or using the computer, the Kaiser report found.
   Use of mobile devices by young kids has soared. A new report from Common Sense Media, a child-advocacy group based in San Francisco, found that 17% of children 8 and younger use mobile devices daily, up from 8% in 2011.

Garage sales are popular at present，but you need to keep an eye on those things and make  sure that you don't fall prey to bad deal．We’ve brought you a list of items that you should  stay away from at all times at a garage sale.

Item 1：Anything related to safety during sporting activities.

If you are new to adventure sports and want to save money on equipment like helmets，wet suits，climbing gears，etc．，you may go shopping at garage sales．However，remember that buying equipment which has been used takes a lot of risks，because the new buyer is unaware of its possible damage．To be safe，buy new equipment or rent it from stores．

Item 2：Anything related to babies．

Baby care items are certainly expensive and that’s why used goods are useful to most young parents．However，as a responsible parent，you will surely consider this a lot before making a decision．For example，stuffed toys may carry the bacteria，so you need to keep in mind that they may bring a health risk to your children．

Item 3：Anything that you sleep on．

Bedding items are a good place for all kinds of harmful insects．While garage sales may offer some tempting bargains，it is wise to stay away from them．If you really need to buy these，you must check on them thoroughly．

Item 4：Anything that requires a perfect fit．

Shoes tend to take the shape of the wearer’s feet after a while．So even if you see a pair of  shoes that is of the same size as yours，it may not fit you well. It is also recommended that you  should give old clothes a miss．

Garage sales are a lot of fun，as we all know．However，don’t be charmed(迷惑)into  buying something that you are unsure of．And save yourself from being at the receiving end of a  raw deal．(不公平的买卖)

A dog running for the first time in his life thanks to 3D-printed prosthetic(假肢)legs has moved a lot of people． 

Derby was born with disabled front legs．While 3D printers have been used to make  replacement limbs(肢体)for humans，Derby is the first animal to be successfully equipped with 3D—printed prosthetics．

Derrick Campana，who helped create Derby’s new legs with designers at the 3D printing  company 3D Systems，has been an expert in that field for the past decade．He specializes in  the creation and use of corrective braces(矫正支架)and man-made limbs．Campana had  worked only with human patients until about 10 years ago．But when a pet fan brought a dog in  need of a prosthesis to him，he discovered he could apply the same technology that he’d  mastered on people to help animals．He also soon learned there was a market for animal  prosthetics and orthotics(矫正术)that hadn’t really been explored，so Campana founded Animal Ortho Care，one of the first companies to make orthotics and prosthetics specifically for animals．Today，Animal Ortho Care is one of five such companies in the world，seeing between 200 and 300 animal patients each month．

“We were really interested in helping Derby，”said Campana．Though 3D printing  technology．has been available for a while，he explained，some of the materials and tools that  work for making human prosthetics aren’t totally suitable for animals．For example，the  technology used to easily scan(扫描)a person’s leg is not as exact when scanning a leg  covered in fur．For Derby，Campana used a fiberglass cast(a special material)，and scanned  that into the 3D printing system．“In the future．hopefully we can just scan the leg directly．’’  he said．

Now that Derby can run，Campana said he is very excited about the good news．More than  three million people on the Internet have watched the video of Derby running on prosthetics．

 “Made in China” has changed

Many shoppers in the West still prize labels，boasting(吹嘘)a product was made in Italy without knowing that a growing number of Italian products come from factories that are Chinese-owned and staffed．The products which were marked “Made in China” gave the buyer an impression of “low pride and low cost，low technology and development。”The statement used to be true，but now it has changed．  

“Made in China” is becoming a leading part in the world market．China’s garment industry(制衣业)has been investing in producing technology and training for decades，and its  workforce has collectively gotten better at sewing garments．As a result，the quality of Chinese-made clothes is rising fast．It has been home to a highly-skilled，highly-specialized garment industry，one that supplies even some high-end(高端的)labels and offers the best mix of price，speed，and quality．

“If I was to make a basic men’s jean，I’d make that in Pakistan，”said Edward Hertzman，co-owner of the trade publication Sourcing Journal．“If I was going to make a fashionable woman's garment，I would move to China because their skill set is better，their hand is better，their finishing is better，and they can handle that type of fashion．”

Indeed，luxury fashion labels now routinely make things in China．Burberry，Armani，and Prada have a11 produced things there，because they’re still able to get good workmanship at a relatively low price．Even the Japanese brand Visvim，known for its crazy attention to detail，also produces high-end，handmade footwear in China．

Despite the rising wages and costs of doing business in China，companies have not walked away．”China is viewed by people who make buying decisions as unique and hard to copy elsewhere，”says Josh Green，CEO of Panjiva．

32．Which of the following is NOT true about “Made in China”?

A．It used to be associated with poor quality．

B．It has lost its leading status in the world market．

C．Its products are recognized by luxury fashion brands．

D．It reflects China’s investment in producing technology．

33．Edward Hertzman thinks highly of “Made in China’’ in such aspects as______.

①workers’ skills               ②low prices       ③advanced technology          ④a sense of fashion

A．①②③    B．①②④    C．②③④    D．①③④

34．What is the similarity between Prada and Visvim?

A．Both of them are from Japan．             B．Neither of them sells at a low price．

C．They both make products in China．        D．They both produce handmade footwear．

35．What can be learned from Josh Green’s words?

A．Doing business in China costs a lot more now

B．Chinese companies are more creative than others．

C．Foreign producers want to copy China’s success．

D．Rising costs stops the interest of foreign companies．   

Mistakes during presentations

Body language is one of the most important ways to communicate with others． 36  Here are three main body language mistakes you should avoid during presentations．

1．Crossed arms

Crossing your arms might give your audience the impression that you are not enthusiastic about your presentation． 37

Keep your back straight，your head up，and your chest and arms “open’’ when you are delivering a presentation．It will give a message of confidence to the audience and make you an approachable presenter．    

2．Jiggling(抖动的)legs

Moving your legs from side to side indicates that you are uncomfortable and restless.

Try moving in the space around you when you are giving a presentation. It is a powerful way to keep the audience attentive．  38   Move when you need to emphasize(强调)a point.

3．Rolling eyes

Most psychologists think rolling eyes is an indication of lying. To some extent，when you    roll your eyes during presentations，you are telling the audience that you don’t respect them.

Begin your presentation with a smile unless you are delivering horrible news．  39    As a result，they will be more willing to listen to you and more likely to be persuaded.

If you use body language inaccurately，the audience may be easily distracted(分心)from   your presentation or even conflict with your ideas·  40

    A．Great speakers have more than one gesture.

    B．Turning the body away from you is a sign of lying.

    C．But too much movement can make you seem nervous．

    D．Meanwhile，maintain eye contact with various people in the audience．

    E．However，using it properly enables you to convey your message successfully.

    F．It shows resistance and will create a distance between you and your audience.

    G．During presentations，you always use gestures and facial expressions to help explain your point．
