Every year billions of pounds are spent on hair loss treatment. If we succeed in curing hair loss with 3D printed hair follicles (毛囊), it will be a huge revolution.
L’Oreal (欧莱雅), the cosmetics firm is partnering with a French bio-printing company called Poietis, which has developed a form of laser printing for cell-based objects. Poietis’ technique begins with the creation of a digital map that determines where living cells and other tissue components should be placed to create the desired biological structure. This involves how the cells are expected to grow over time. The file based on the digital map is then turned into instructions for the printing equipment, so that it can lay down tiny droplets (小滴) made out of the cell-based "bio ink" one layer at a time. The printing process involves bouncing (使反弹) a pulsing laser (脉冲激光器) off a mirror and through a lens, so that when it hits a ribbon (色带) containing the bio ink, a droplet of the matter falls into place. About 10,000 of these micro-droplets are created every second.
It typically takes about 10 minutes to print a piece of skin 1cm wide by 0.5mm thick. However, since hair follicles are complex and consist of 15 different cells in a structure, they may take longer.
Poietis is not the only company working on bio-printing, but most others use another way, which involves pushing a bio-ink through a nozzle (喷嘴), rather than lasers to build their tissue. Poietis suggests its technique puts less stress on the biological matter, meaning there is less risk of causing it damage.
Alopecia UK — a charity that provides support and advice about hair loss — has mixed feelings about the development. “It is encouraging to know that companies such as L’Oreal are investing in technology that may help those with hair loss in the future,” said spokeswoman Amy Johnson.
“However, we would suggest it’s still very early to be getting excited about what this potentially could mean for those with medical hair loss. At this point it is unclear as to whether this technology could benefit those with all types of hair loss.”
“Also, if this new technology does lead to a treatment option, given the high costs of existing hair transplant procedures, how many people will be able to realistically afford any new technological advances that may become available? As with any other research and development into processes that may be able to help those with hair loss, we watch with great interest.”
1.What does Paragraph 2 mainly tell us?
A.How the printing process is carried out.
B.Where the living cells should be placed.
C.How long the cells are expected to grow.
D.What the printing equipment is made up of.
2.What does the underlined word “it” in Paragraph 4 refer to?
A.hair follicle B.biological matter
C.nozzle D.bio-ink
3.The passage implies that the new technology may ______.
A.meet some practical challenges
B.help people with hair loss at present
C.offer solutions to all problems of hair loss
D.cost a large sum of money to transplant hair
4.What is Amy Johnson’s attitude towards the new technology?
A.Disapproving. B.Optimistic.
C.Cautious. D.Negative.

Dash of Hope
"Dash" is a symbol which represents every day we've spent alive on earth. Therefore, how you spend your "dash" is important.
Recently I 36 about a little girl named Hope. After learning more about her life, I couldn't help but feel it was not by 37 , nor happenstance（意外事件）, that she had been named "Hope". The strong feeling of sympathy and generosity 38 in her young heart made a lasting impression on me and countless others. 39 I never had the opportunity to meet her, I wish I had. It seems as though she was wise beyond her tender years and very, very special.
Hope was a twelve-year-old girl who was 40 a "wish" in early December 2010 by the "Make-A-Wish" Foundation after being 41 that she had a rare type of bone cancer. However, when she found out that more than 150 42 in her area were waiting for their wishes to be achieved , she unselfishly used her wish to 43 that those children have their wishes granted. She also asked that it be done 44 January 16, 2011. Unfortunately, however, the organization informed her that her 45 request could not be granted as the funds were simply 46 . They calculated that they would need to raise more than one 47 dollars in thirty days in order to grant her wish. 48 , but not discouraged, she turned her disappointment into an enthusiasm that inspired caring 49 to take up helping grant the wishes of the other children, and eventually 50 as well. Newspaper columnists and reporters for radio and TV stations 51 the story of this caring young girl who had 52 the hearts of so many and as word spread, the community was challenged. Committees were fanned and schools, corporations and various organizations assisted in 53 money to help make Hope's dream come true.
Her efforts were not in vain as they continue to help others, not only 54 , but spiritually and emotionally as well. At the gathering to celebrate her life, "A Celebration of Hope" on January 16, 2011 , the 55 was made that they had indeed received donations totaling more than one million dollars. Her wish had been granted!
