交作业啦～～～ 这次的话题都很有趣味～

(21-16) Wed
Time1 – 1’19” word[210]
P1: Topic – glacier can protect mountain top.
P2: Mont Blanc is on the boarder of Italy and France. The glacier on MB has changed skiers, climbers, and scientists…
P3: Old opinion – glaciers erode surface and move sediment. New opinion – also protect mountaintops that away from equator. MB grows a certain height every year with the protection of the glacier.

Time2 – 1’33” word[221]
P1: Scientists compare the erosion rates at different summits of Mont Blanc
P2: Erosion rate under the coldest ice is 16 times less than under temperate ice. The fastest erosion rate happens under the weighty ice that melts every year.
P3: Another scientist said that roles of glaciers are different. Not all glaciers protect mountaintop. Glaciers with a wet base is the most erosive.
P4: The roles of glaciers will change as global warming and temperature rise.

Time3 – 忘记记时了。。。 word[337]
P1: Scientists now can grow human livers in a vitro and then transplant them into mice.
P2: This effort can help people replace them organs. But the challenge is to grow a 3D organ.
P3: Scientists first let liver cells grow into a liver bud in a vitro then transplant into mice. It turned out that the liver bud grew into a 3D liver. On mice whose immune system  damaged, the livers grow and function. Promising new approach…

Time 4 – 1’22” word[254]
P1: The study means the developed organ can grow in mammals. Scientists hope to test on primates. Researchers say this is an important progress. The technique can be used on other organs too.  
P2: However the major challenges include the health and safety checks and the developing cell. Because of the challenge, the application on humans will be at least decays away.

Time5 – 1’54” word[299]
1.        The increase in the water content of PMCs may be the result of more rockets sent to the space.
2.        Explain what PMCs are (they are so high that they can catch sunlight).. Some evidences: comparison of data in different timeframes etc.
3.        Explain the phenomenon: more rockets sent to the space bring more water to the upper atmosphere, which is usually dried up by the sunlight.

Time6 – 5’04” word[1005]
1. More people have been attacked by sharks in recent years. A researcher at the University of Sydney gave some suggestions on how to avoid shark attack.
2. He asks himself three what’s questions when going to swim in a ocean:
1) what’s the weather? Stormy whether and cloudy water is no good for swimming. No swimming after 24 hours of a storm, not just the 2nd morning.
2) what’s the swimming environment? Go swimming in a group and stay close to the group. Fishers around with bait is no good.
3) what am I doing? Wear no jewels. Sharks can be curious.  
3. His recommendations to town with shark attack risks.
1) signs – tell ppl ocean is not a swimming pool. Let them know the risk.
2) swimming close to the shore -
3) information – shark attack risks are highest at the water temperature between 64 to 68 F. Let ppl know the water temperature and let them estimate their risk.
4. His rec to a town in Mass.
information, nearby hospitals, etc.

The research suggested glacier can protect mountain top from eroding.
2-1'55
How to testify the experiment assumption and other factors such as global warming might affect the eroding rate.
3-3'14
A experiment about creating liver precursor cells to strength the human's immune system.
4-1'41
A lot of work to do the liver experiment and we might wait for decades years.
5-2'35
The PMC can be observed on the highest latitude and altitude because it's the coldest place on the Earth.

Tha author mainly introduce how to face the shark-bite.
The author clarify his individual position on three What's rules, that is , what's the weather? what's the environment? what am I doing?
And he suggests choose fit temperate, nearly the shore and play in group when you go to the seaside. On earth, the sea is not a pool.  
Moreover, the author advises the government should provide amplify information to the public to remind them the safety in case the shark-bite.
And government should pay attention to the measures after people are attacked by shark.

T1-1’34
Glaciers protect the mountain from erosion and help it gain height.
P1-theory
P2-example (Mont Blanc)
P3-glaciers, typical role VS role in protect mountaintops far from equator (the examples)
P4-the same processes are happening on mountains worldwide (Buo reaffirm)

T2-1’36
P1-study (Cec God)
P2-weighty presence of ice tempers abrasion of the underlying bedrock in nonglaciated ice (finding)
P3-glaciers with a wet base are very erosive (Mar Bra oppose)
P4-glaciers, role could change as temperature s rise with global warming (Buo add)

T3-2’22
T4-1’25
Goal of different experiments is to transplant the cell into humans and let them develop into replacements for diseased or damaged organs. But there are significant hurdles to clear before the technique reaches the clinic.

T5-1’57
An unexpected increase in the water content of PMCs at high attitudes over polar regions may be the result of more rocket launches.

T6-4’
Explain how communities around the world are responding to similar incidents, and what the thousands of Americans can do to reduce their chances of encountering a shark by citing three repots.

Mont Blanc’s been gaining height thanks to its glacier, which protects the mountain from erosion. The same processes are happening on mountains worldwide.

1’33
The erosion speed is far less efficient beneath the coldest ice glacier. But it may not be apply to all the mountains and the role of glaciers could change as temperatures rise with global warming.

2’
By using the iPS, scientists successfully grow human livers in mice.

1’20’’
The contribution of the tech and its hurdles to clear before the technology reaches clinic.
