Dear Bob,

I¡¯m glad to have received your E-mail and thank you for your concern about my preparations for the coming College Entrance Examination.

Dear Bob,

I¡¯m glad to have received your E-mail and thank you for your concern about my preparations for the coming College Entrance Examination. I have made great progress in all my subjects and become increasingly skillful at answering the questions. There are, however, still some problems with my studies. All my subjects, for example, are just above the average and none of them ranks top in my class. Confident but a little worried, I¡¯m now busy with my studies from morning till night, making use of every minute to learn more. In the months ahead, I will, on the one hand, try to improve efficiency and do more exercises to have a better insight into the questions. On the other hand, I will try to keep calm and confident, making sure that I¡¯m always at my best for every exam. I believe I will succeed in the College Entrance Examination. (127 words)

Sincerely

Lihua.

After I made it to the city center, I started to feel it might be easy for a foreigner to deal with the great size of Beijing. With growing confidence, I decided to take the subway to the hotel, not realizing that the network didn¡¯t go that far. Impressed with the cleanliness of the station, I bought a ticket and boarded the first train that came along.

After a few minutes I asked in English of course a young man seated next to me where I should get off closest to the Friendship Hotel. Wearing a smart business suit and tie, he would surely speak English, wouldn¡¯t he? Unfortunately, he couldn¡¯t understand me but seemed very friendly. I showed him the room card with all the information of the Friendship Hotel in Chinese characters. He looked at it, and then his eyes moved quickly to the carriage £¨³µÏᣩ subway map. Next, he raised three fingers of his right hand.

In Australia, raising fingers at someone is not usually nice, but this man wasn¡¯t smiling. At the next station he showed me two fingers. Now in Australia, that¡¯s really rude, but I got the message. When we stopped at the third station, he didn¡¯t just point to the door, but got up, took me out of the train, and led me to the top of the stairs, and out onto the street. Then he stopped a taxi and told the driver where to take me.

All this came from a man who couldn¡¯t speak my language, and I couldn¡¯t speak his. I was now speechless, especially when he refused my offer of money. I felt a little embarrassed having even thought he would accept a tip.

This experience made it clear I had to learn some Chinese quickly or my adventures might start turning into bad luck.

Researchers are now using 3D printing to create models of the human heart to help heart specialists. The heart doctors can use the models to better help patients before an operation.

Dr. Bramlet, a children¡¯s heart expert at the University of Illinois College of Medicine, says the 3-D models show information he cannot get any other way.

¡°And so what we¡¯ve done with the printed models? We¡¯ve pulled it out of the screen so that you can actually hold it in your hand and evaluate the anatomy£¨½âÆÊ£©.¡±

A 3-D printer uses images from a digital display to create a physical model of a human heart. Matthew Bramlet says doctors can use the model to understand the anatomy.

Pictures from medical tests like CAT scan or MRI are sent to a 3-D printer to create a heart in a plaster£¨Ê¯¸à£©form. The printer then constructs the heart, thin layer by thin layer. Dr. Bramlet says the model matches the real heart in every detail. ¡°When we¡¯re done with the model and made our decision, we want to be able to go back to the source image and confirm those findings,¡± he says.

Dr. Bramlet has built model hearts for different kinds of heart operations. All of the operations were successful. In his first case, digital images showed only one tiny hole in a baby¡¯s heart. But, the 3-D printed model showed several defects or problems that the baby was born with. Dr. Bramlet says those defects could not be seen easily in the images. The heart surgeon was able to change the type of surgery for the patient based on the 3-D model. He added that 3-D heart models saves time during heart operations.

Kathy Magliato is a heart surgeon at Saint John¡¯s Health Center in Los Angeles. She welcomes the new technology. She says it could help her make better decisions before she operates on the hearts of her patients.

¡°I can then take this very complicated structure before the operation and I can hold it in my hand and plan an operation around what I¡¯m seeing, touching and feeling. That to me is what can potentially change the game in an operation and save lives.¡±

Dr Bramlet continues to research the technology. He is working with the National Institutes of Health to build a 3-D library that includes heart models and images that others can use.
