Most penguins died after a huge iceberg grounded near their habitat in Antarctica，forcing them to make a long way to find food, scientists say in a newly published study. The B09B iceberg, measuring about 100 square kilometers, grounded in Commonwealth Bay in East Antarctica in December 2010, the researchers from Australia and New Zealand wrote in the “Antarctic Science” journal.

The Adelie penguin population at the bay’s Cape Denison was measured to be about 160,000 in February 2011 but by December 2013 it had decreased to about 10,000, they said. The iceberg’s grounding meant the penguins had to walk more than 60 kilometers to find food, preventing their breeding attempts, said the researchers from the University of New South Wales’ ( UNSW) Climate Change Research Centre and New Zealand’s West Penguin Trust.

“The Cape Denison population could disappear completely within 20 years unless B09B relocates or the fast ice within the bay breaks out,”they wrote in the research published in. Fast ice is sea ice which forms and stays along the coast. During their survey in December 2013 , the researchers said “hundreds of abandoned eggs were noted, and the freeze-dried dead bodies of previous season’s little penguins lay everywhere on the ground.”

“It’s strangely silent,”UNSW’s Chris Turney , who led the 2013 exploration , told the“Sydney Morning Herald Friday”.“The ones that we saw at Cape Denison were terribly low-spirited , almost unaware of your existence . The ones that are surviving are clearly struggling. They can hardly survive themselves , let alone give birth to the next generation. We saw lots of dead birds on the ground.”

In contrast, penguins living on the eastern edge of the bay just 8 kilometers from the fast ice edge were full of vigour, the scientists said. The researchers said the study had important influence on the wider East Antarctic if the current situation of increasing sea ice continued. Sea ice around Antarctica is increasing, in contrast to the Arctic where global warming is causing ice to melt and icebergs to decrease. Scientists believe the growth in Antarctic sea ice is likely to be driven by changes in wind and local conditions before long.

1. What’s the main reason why the Adelie penguin population decreased?

A. Many Adelie penguins died from the cold weather in Antanctic.

B. They didn’t have enough time to give birth to and raise babies.

C. The iceberg’s grounding killed a number of Adelie penguins.

D. Adelie penguins lost their habitats so they couldn’t breed.

2.Which statement is correct according to the passage ?

A. The life of penguins in Cape Denison was very hard.

B. Penguins in Cape Denison were afraid of humans .

C. The sea ice in Antarctica is decreasing faster than before.

D. Human activities caused much damage to Cape Denison.

3. What does the underlined word “vigour”in the last paragraph mean ?

A. Trouble. B. Food. C. Energy. D. Joy.

4. What’s the main idea of the passage ?

A. Global warming caused penguins’ death.

B. Iceberg harmed penguins’ life.

C. Penguins need more habitats.

D. Antarctic extreme weather caused penguins’ death.

You ________ give me a lift. I want to walk home for exercise.

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, the cosmetics firm is partnering with a French bio-printing company called Poietis, which has developed a form of laser(激光) 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 made out of the cell-based "bio ink" one layer at a time. The printing process involves bouncing a pulsing laser 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 follicleB. biological matter

C. nozzleD. 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.
