4.An Israeli law banning too-skinny models went into effect with the start of 2013.The law,approved last March in Israel,requires models to prove they have maintained a Body Mass Index (BMI) of at least 18.5 for three months before a fashion show.That means a woman who is 5'8"tall can weigh no less than 119 pounds.
"This law is another step in the war against eating disorders,"said physician Adatto."Underweight models,"he explained,"can no longer serve as rold models for innocent young people who copy their false image of being skinny."
But some critics in this country say it is misguided,focusing on weight instead of health.They also say the Israeli ban is bound to fail because of the strong power of the fashion industry."I think it's an approach that isn't going to work."Said eating disorder expert Susan Ice,who worked with an organization wich creates a healthy working environment for models.
But Adatto told the reporter that he began to concern the issue after meeting an aspiring model who looked like she needed to be hospitalized.He said."I realized that only legislation can change the situation.There was no time to waste,so many girls were dieting to death."
However,the efforts to regulate models's weight in Spain and Italy have not resulted in part because of difficulties in determining reliable methods of measuring weight and health."
?Still,folks including Ice say there's no denying that images from Hollywood and the fashion industry can be difficult for young women to deal with."Certainly I don't believe the modeling industry has caused the rise in eating disorders,but it makes it harder,"she says."It's a difficult recovery environment,worshiping thinness as the beauty ideal."

5.See a cellphone cover that you like on Taobao?Forget about placing an order,paying the bill online and waiting for days for it to be delivered to you.In the near future,you'll be able to get it in minutes just by hitting"print"on your computer.You might find it hard to believe that you could actually"print"an object like you would a picture.But it is not that hard to understand how it would work.Just as a traditional printer sprays ink onto paper line by line,modern 3D printers spread material onto a surface layer by layer,from the bottom to the top,gradually building up a shape.Instead of ink,the materials the 3D printer uses are mainly plastic,resin and certain metals.The thinner each layer is-from a millimetre to less than the width of a hair-the smoother and finer the object will be.This may sound like a completely new technology,but the truth is that 3D printing has been around since the late 1980s.Back then,it was barely affordable for most people,so few knew about it.Last year,though,saw a big change in the 3D printing industry-printers became much cheaper.For example,10years ago a desktop 3D printer might have cost£20,000,while now they cost only about£1,000,according to the BBC.Taken out of the factory and introduced to more diverse and common uses,3D printing can create just about anything you can think of-flutes,bikinis,jewelry,aircraft parts and even human organs.In fact,scientists from Cornell University in New York have just made an artificial ear using a 3D printer,according to Science Daily.The fake ear looks and acts exactly like a natural one.However,as 3D printing becomes more common,it may bring about certain problems-such as piracy."Once you can download a coffee maker,or print out a new set of kitchen utensils on your personal 3D printer,who will visit a retail store again?"an expert in 3D printing told Forbes News.Even more frightening,what if anyone in the world could use a 3D printer to print out a fully functioning gun?
8.According to the article,in the future,the 3D printing technology willB.
A.enable people to make better purchases online   
B.change the way we make many products   
C.be applied as widely in our daily life as computers   
D.shorten the time it takes for people to get what they buy online

D.The 3D printer became more affordable for consumers.
10.How is the last paragraph developed?A
A.By giving examples.B.By making comparisons.
