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 barely 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 commonplace, 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 (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?

With a VISA card in your hand, the world opens up to you. With more than 24 million places across the world accepting VISA, you can use your VISA card instead of cash to pay for your everyday purchases—whether you are shopping at the grocery store, dining at a restaurant, filling your car with petrol or buying the perfect gift on your travels.

It’s impossible to determine how many people would have lost their lives without the contribution of African-American inventor Dr Charles Drew.
Charles Drew was born on June 3, 1904, in Washington, DC. His early interest was in education, but he was also an outstanding athlete. While in college, he was awarded as the man who contributed the most to sports during his four years in school. Drew’s sister Elsie suffered from tuberculosis(肺结核) and died in 1920. Her death influenced his decision to study medicine.
After becoming a doctor and working as a college instructor, Drew went to Columbia University, where he earned his Doctor of Medical Science degree. During this time he became involved in research on blood and blood transfusions.
At Columbia, he wrote a paper on “banked blood”, in which he described a technique he developed for the long-term preservation of blood plasma. Before his discovery, blood could not be stored for more than two days because of the rapid breakdown of red blood cells. Drew had discovered that by separating the plasma from the whole blood and then refrigerating them separately, they could be combined a week later for a blood transfusion. Drew became the first African American to receive a PhD in medical science.
After World War II broke out, Drew was called upon to put his techniques into practice. He was named a project director for the American Red Cross but soon quit his post after the government issued an order that blood taken from white donors should be separated from that of black donors.
On April 1, 1950, after he attended the annual free clinic at the John A. Andrew Memorial Hospital, he and other three physicians decided to drive back home. As he was tired from spending the night before in the operating room, he lost control of his car. Drew was badly injured and was taken to Alamance General Hospital in Burlington, North Carolina. He was pronounced dead half an hour after he first received medical attention. Drew's funeral was held on April 5, 1950, at the Nineteenth Street Baptist Church in Washington, DC.
But contrary to popular thought, he was not refused a blood transfusion by an all-white hospital. He indeed received a transfusion but was beyond the help of the doctors attending to him. As Dr. John Ford, one of the doctors who survived the accident, later explained, “We all received the very best of care. The fact that he was a Black did not in any way limit the care that was given to him.” Over the years, Drew has been considered one of the most honored figures in the medical field.
【小题1】According to the passage, ________ might have contributed to the invention of blood banks.

An order has come that the police should find out where the thief__________.?

A.hides                                             B.was hiding

C.hiding                                            D.is hidden

Last week I went to visit to my former neighbor, Mr. Yang. He and I used to living next to

each other for many years. About half a year ago, an order came which the old building, along

with many other similar ones, were going to be pulled down to make room for a main street.

So I had to move apart. Mr. Yang now lives in the suburbs near a beautiful park. His new

apartment is much big than before. The only problem is that it took quite a long time to get to

the downtown area. Therefore, Mr. Yang doesn’t seem to worry about the long distance. He

says that new subway line is to be built in a few year and he is sure life will be better in

the future.
