Swedish master medical photographer Lennart Nilsson is a pioneer in medical photography．In association with researchers and with the help of advanced, specially designed equipment, he has documented the inside of man down to the level of a cell with his camera.
Born in Strängnäs, a satellite city of Stockholm, in 1922, Nilsson got his first camera from his father when he was 11 years old．From the early stage, he has been interested in looking at ants and taking photos of them.Throughout the years, he has devoted special attention to capturing the creation of a human being, from conception to birth.
In 2006 when his photo book Life was published in both Swedish and English, he was invited to give a lecture at the Stockholm bookstore．He vividly described to the public how he took the photos so that the development process of the embryo can be understood better．Finally when he was signing his name in the book, I asked him what made him so passionate about working on this, he stopped writing and thought for a second, “I think it is the respect for life,” Nilsson said.
Nilsson began his career as a photographic journalist in the middle of the 1940s and published a number of photo-essays in Swedish and foreign magazines, including "Polar Bear Hunting in Spitzbergen" (1947) and Midwife.
“When I went to the professor to take the embryo photo, I was looking around and then I saw something which was unbelievable, it was a tiny human embryo lies in a very special place, a 10-20 millimeter embryo with hands, arms and eyes, and I got a shock,” Nilsson said.
Nilsson began experimenting with new photographic techniques in the mid-1950s to report on the world of ants and life in the sea．His revealing macro-studies were published in his book on ants, Myror (1959), and in the Life in the Sea (1959), and in Close to Nature (1984)．In the 1960s special designed, very slim endoscopes (内窥镜))made it possible for him to photograph the blood vessels and the cavities (空洞) of the body with the necessary depth of field and, in 1970, he used a scanning electron microscope for the first time, he was also considered the pioneer for three dimension digital pictures of the body organs.
After his photographs of human embryo were published, he was encouraged to continue photographing the origins of human being.
Nilsson is very modest and sincere．At age of nearly 88, he is still cooperating with colleagues in Karolinska Institute where the Nobel Prize in Physiology or Medicine is selected every year.
“He can forget all the other things when he is working and he is still working diligently,” Mrs Nilsson told People’s Daily Online.

Why does the Leaning Tower of Pisa in Italy lean? It leans because of a mistake. It has leaned almost since the day the tower was built.
In 1173, the people of Pisa, Italy, wanted to build a bell tower. They wanted the tower to be the most beautiful bell tower in all of Italy. The city also needed a bell tower because the church did not have one.
However, there was a problem. As soon as the first floor of the building was finished, the tower started to lean. Builders tried to make the building straight again as they added more floors, but they couldn’t figure out how to make it stop leaning.
It took almost 180 years to finish the tower. Since then, the tower has leaned by another millimeter every year. Today, the Leaning Tower has eight floors and is 54.5 meters tall. By 1990, it was leaning by about 4 meters to one side. It was also slowly sinking into the ground. Many people became worried that it would soon fall apart.
In 1998, repair works began on the tower, and by the end of 2001, it had been moved back by 45 centimeters. The tower will still lean, however, so it will need to be repaired again---in another 200 years.

Imagine that the genome (基因组) is a book. The book consists of 23 chapters with thousands of stories made up of paragraphs, words and letters on different levels. There are one billion words in the book, which makes it longer than 5,000 volumes the size of this book, or as long as 800 Bibles. If I read the genome out to you at the rate of one word per second for eight hours a day, it would take me a century. If I wrote out the human genome, one letter per millimeter, my text would be as long as the River Danube. This is an enormous document. A huge volume, a cook book of great length, and it all fits inside the extremely small nucleus (核) of a tiny cell that fits easily upon the head of a pin.
The idea of the genome as a book is not, strictly speaking, even a metaphor (比喻), It is true to a great extent. A book is a piece of digital information, written in one-directional form and defined by a code that translates a small alphabet of letters into a large dictionary of meanings through the order of their groupings. So is a genome. The only complication is that all English books read from left to right, while some parts of the genome read from left to right, and some from right to left, though never both at the same time.
While English books are written in words of different lengths using twenty-six letters. Genomes are written entirely in three-letter words, using only four letters, And instead of being written on flat pages, they are written on long chains of DNA molecules (分子), The genome is a very clever book, because in the right conditions it can both photocopy itself and read itself.

A small group of people around the world have started implanting(移植) microchips to link the body and the computer.
Mr. Donelson and three friends, who had driven 100 miles from their homes in Loekport, New York, to have the implants put in by Dr Jesse Willemaire, whom they had persuaded to do the work, are part of a small group, about 30 people around the world, who have independently put in microchips into their bodies, according to Web-based reports.
At a shop William Donelson was having a four-millimeter-wide needle put into his left hand. “I’m set,” he said with a deep breath. He watched as the needle pierced(刺穿) the fleshy webbing between his thumb and a microchip was set under his skin. At last he would be able to do what he had long imagined; strengthen his body’s powers through technology.
By putting the chip inside—a radio frequency identification device (RFID)—Mr. Donelson would have at his fingertips the same magic that makes safety gates open with a knock of a card, and bridge and tunnel traffic flow smoothly with an E-Zpass. With a wave of his hand he plans to connect with his computer, open doors and unlock his car.
Implanting the chip was relatively simple task but very meaningful to Mr. Doneselson, a 21-year-old computer networking student so interested in the link between technology and the body that he has data-input jacks(数据输入插空) inside his body. They might lead to an imagined future when people can be connected directly into computers. His new chip is enclosed in a glass container no bigger than a piece of rice and has a small memory where he has stored the words “Technology”.
Some doctors have done the piercing in people’s homes, and others have implanted chips in their offices after patients signed forms showing the fact that long-term studies have not been done on their safety. Piercers treat the implants much like any other medical operation steps, instructing people to keep the site dry, and advising them that swelling(肿) and redness should last a week.
69. With a RFID implanted, which of the following will Mr. Donelson be able to do?
Make a safety gate open with a knock of a card.
Make bridge and tunnel traffic flow smoothly with an E-Zpass.
Open doors and unlock his car with a wave of his hand.
Turn his body and brain directly into computers.
70. The underlined word “they” in paragraph 5 refer to “___________”.
A. glass containers                             B. implanted computer chips
C. data input jacks                                    D. computer and net working students
71. Which of the following would be the best title for the passage?
A. High Tech, Under the Skin                     B. A Needle, So Magic
C. Donelson, a Powerful Man                     D. Data-input Jacks, Inside the Body
72. We can conclude from the passage that __________________.
Mr. Donelson has made a large sum of money by the piercing.
the Piercers are people working in the computer field
the piercing has no side effect and it will make people intelligent
the long term effects of these implants are not yet known

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?
