When the Berlin Wall came down in 1989, Leonard Bernstein gave a concert in Berlin, including Beethoven's Ode to Joy, with the word "Joy" changed to "Freedom" in the lyrics sung．The orchestra（管弦乐队）were drawn from both East and West Germany, as well as the United Kingdom, France, the Soviet Union, and the United States．

Freedom was in the air and it was not just for people． The wall between East and West Germany had also kept a large population of wild pigs within the eastern forests of Brandenburg．The wall's falling down made it easier for the big pigs—a very big one can weigh over 300 pounds—to leave the woodlands and walk into the town． Warm winters and easy access to food have helped the population increase． Now about 10,000 wild pigs walk around Berlin．

The nature of the beast has added to the boom（兴旺）．"The pigs are intelligent," says Marc Franusch, a spokesman for the Berlin forestry department． "They learn to use the neighborhoods．They get used to people, dogs, and traffic．"  

The wild pigs tend to travel in small groups and have been found searching rubbish and gardens, feeding their piglets（小猪）in the shadow of parked cars, and crossing busy roads．On average, the animals are involved in one traffic accident every day． And despite the fact that it's illegal, some Berliners have been known to give the pigs food．

Though wild pigs are protected under German law, the city's forestry department is permitted to kill 2,000 of the creatures every year, targeting mostly young adult animals in forests surrounding Berlin． Pigs within city limits are only shot if they make an immediate threat．No humans have yet been seriously wounded by them, but local dogs have been the victims of their tusks． "The forestry department is not aiming to get rid of the pigs," explains Franusch, "but we do have to reduce dangerous situations．"

1.The concert in the first paragraph is given to          ．

A．celebrate Bernstein's success              B．remind people of fighting for rights

C．show the artists' delight of life              D．express people's joy for freedom

3.From the text we can know that          ．

A．in Berlin people can never kill any wild pig

B．it is against law to offer food to wild pigs

C．wild pigs each weigh more than three hundred pounds

D．traffic accidents are mainly caused by wild pigs in Berlin

4.The article mainly talks about           ．

A．why wild pigs in Berlin enjoy so much freedom

B．when wild pigs were united in Berlin

C．how wild pigs are living in Berlin

D．what damage wild pigs have done to Berliners

See a cell phone 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 (喷) ink onto paper line by line, modern 3-D 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 3-D printer uses are mainly plastic, resin (树脂)and certain metals. The thinner each layer is --- from a millimeter 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 3-D printing has been around since the late 1980s. Back then, it was hardly affordable for most people, so few knew about it.

Last year, though, saw a big change in the 3-D printing industry--- printers became much cheaper. For example, 10 years ago a desktop 3-D printer might have cost £20,000 (200,000 yuan), 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, 3-D printing can create just about anything you can think of ---flutes (笛子), 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 3-D printer, according to Science Daily. The fake ear looks and acts exactly like a natural one.

However, as 3-D printing becomes more common, it may bring about certain problems --- such as piracy(盗版). "Once you can download a coffee maker, or print out a new set of kitchen utensils (餐具) on your personal 3-D printer, who will visit a retail (零售的) store again?" an expert in 3-D printing told Forbes News. Even more frightening, what if anyone in the world could use a 3-D printer to print out a fully functioning gun?

1.According to the article, in the future, the 3-D printing technology will ___.

A．enable people to make better purchases online

B．be applied as widely in our daily lives as computers

C．change the way we make many products

D．shorten the time it takes for people to get what they buy online

2.What was the big event happening in the 3-D printing industry last year?

A．The 3-D printing technology was taken out ofthe factory.

B．The 3-D printer became more affordable forconsumers.

C．The 3-D printer was used for medical treatmentfor the first time.

D．3-D printing technology began to be used invarious fields.

3.How is the last paragraph developed?

A．By analyzing a cause and an effect.          B．By making comparisons.

C．By giving examples.                      D．By presenting research findings.

4.What is the best title of the passage?

A．Printing out everything                   B．Technology in the future

C．Online shopping disappearing              D．Great demand for 3-D printers

Over the years, Americans have become used to salt．Most people have no idea how much salt they consume-on average, about 9 to 12 gram per person per day, according to the American Heart Association．That's twice the amount recommended by the government．

A new study last week showed eating even a little less salt could greatly help the heart．The scientists said the results would be thirteen percent fewer heart attacks, eight percent fewer strokes（中风）, four percent fewer deaths and eleven percent fewer new cases of heart disease．

Researchers also found that the benefits would be greatest for African Americans and women．As a group, African Americans tend to have higher blood pressure than the general population, and "many studies suggest that they may be more sensitive to salt," says Dr.Kirsten Bibbins-Domingo, an epidemiologist（流行病学家）at the University of California, San Francisco．Her analysis found that a reduction of 3 gram of salt per day would reduce heart attacks 8% on average; among African Americans, that rate would drop 10%．A similar result was found in women, whose stroke risk dropped 8% with a 3-g reduction in salt intake; in men, the risk fell 5%．

They and public health professionals in the United States are interested in a national campaign to persuade people to eat less salt．

However, other scientists say such a campaign is an experiment with the health of millions of people．

Michael Alderman, a high blood pressure expert and professor at Albert Einstein College of Medicine in New York, says that eating less salt results in lower blood pressure．But he says studies have not clearly shown that lowering salt means fewer heart attacks or strokes．

“Salt has other biological effects． Calling for reductions in the national diet could have good effects, as well as harmful results． There is not enough evidence either way,”said Michael Alderman．
