The Father of 3D Printing

About twenty years ago, the surgeons at the Wilford Hull medical center working to separate a pair of conjoined(连体的) twins thought that only one would be able to walk after the operation. After a model of the girls’ bone structure was 【1】 using 3D printing, however, they found a shared upper leg bone to be bigger than expected and split it successfully, 【2】 in both twins being able to walk. Now eighty and still working as chief technology officer of 3D Systems. Chuck Hull is enjoying some minor 【3】 31 years after he first printed a small black eye-wash cup using a new method of manufacturing known as 3D printing.

At the time, he was working for a company that used UV light to put thin layers of plastic coats on tabletops and 【4】. He had an idea that if he could place thousands of thin layers of plastic on top of each other and then cut their shape using light, he would be able to form three dimensional objects. After a year, he 【5】 a system where light was shone into a bottle of photopolymer – a material which changes from liquid to plastic-like solid when light shines on it – and traces the shape of one level of the object. Subsequent layers are then printed until it is 【6】.

After patenting the invention, he set up 3D Systems, 【7】 getting $6m (3.5m) from a Canadian investor. The first 【8】 product came out in 1988 and proved a hit among car manufacturers, in the aerospace sector and for companies designing medical equipment. The possibilities appear endless – from home-printed food and medicine to 【9】 that pictures of objects be able to be taken in shops and then recreated using plans downloaded from the Internet Although deliberate in his responses, there is one moment when the 【10】 spoken Chuck Hull tells of his surprise about what exactly his creation was capable of achieving.

【题目】The fact that she looked like a sensitive, friendly girl didn’t matter. ______, it made me even angrier.

A. If any B. If anything

C. If so D. If not

【题目】Directions: Complete the following passage by using the words in the box. Each word can only be used once. Note that there is one word more than you need.

“Life of Pi” is narrated by an older Pi and takes place in the present as he tells his life story to a writer. Pi begins with how he got his name and how his family owned a zoo, but eventually leads into his family needing to leave India for financial 【1】. The heart of the story lies in Pi as a young man and the time he spent out at sea on a lifeboat with a tiger named Richard Parker, but getting to that point is quite an ordeal（苦难考验）. Pi loses everything and everyone close to him in the blink of an eye and he doesn’t 【2】 on making what feels like an unbreakable bond with a Bengal tiger.

The 【3】 film offers a rather marvelous message about religion as Pi discusses the experimentation with several different religions as a young boy. Even though it seems kind of silly that a boy has 【4】 so many religions at one point in his life, it portrays a/an 【5】 message in a light that doesn’t seem too preachy（说教的）. But the religious aspect is really only a backdrop for being on your own 【6】 to finding who you really are. Feeling so alone for so long and having Pi talk about not being alone and not getting to say goodbye to those he cared about most is one of those things that just hits you really hard.

While witnessing Pi attempt to tame Richard Parker is really 【7】, there are so many unbelievable sights to witness in “Life of Pi”. There’s the whale, the jellyfish, the flying fish, that 【8】 storm, and that seaweed island with all of the meerkats (a kind of monkey). “Life of Pi” never really lets up on being 【9】 breathtaking and amazing from beginning to end.

“Life of Pi” is pleasantly satisfying. With a heartfelt message, beautiful visuals, and stunning camera work. “Life of Pi” is truly a sight to behold and illustrates how 【10】 3D can be to a film that isn’t just a summer hit or blockbuster.

Dear Bill,

I’m glad to receive your letter. Thank you for your caring for the weather or my health. Now I’d like to tell you anything about the smog.

Since last winter, the smog has been occurred a lot of times. It has done great harm to our daily life—a great number people got sick; many traffic accidents happened and quite lots of flights had to be put up. Luckily, people have realized the serious harm causing by the smog and the importance of protecting the environment. People all over the country are taking measure to reduce the smog. As for me, I will go to school by bike or on foot, and I wouldn’t throw the waste anywhere. Beside, I will tell people around to try their best to protect the environment. Would you like to tell me some other good ideas?

Looking forward to receive your reply.
