TIME1 0:34
The glaciers mostly account for the rising sea lever during the 2000s
TIME2 1:44
Even in frigid areas, the sea life will adapt themselves to climate change(the authro takes an shocked findings as an example then to validate it)
TIME3 1:31
The scientist have found data to justify the prediction that the solar system has a tail, even though they cannot meature its length.
- it talks about how scientists found the tail and what does the tail looks like
TIME4 1:23
The lastest finding has revealed that T hunted for live prey.
- What the scientist assumes before
- how the latest finding found the different conclusion-fossils
- depict the evidence further
TIME5 1:33
There is still disagreements about how T hunted for prey.Some scientists thought there are not differences based on the new found fossils.
time 1: 0:53
sea level rise as the ice sheets themselves contributed during that time.
time2 :1:"49
enterprising delicate creatures called glass sponges showed up with unprecedented speed to stake their claim. The finding suggests that even in frigid places, sea life may adapt rapidly to climate change.
time3 :2:"38
Scientists had always presumed that a tail existed,But this is the first time we have data that tells us about the tail.The IBEX team could not determine the exact length of the tail
time4 : 3'01
there was no hard evidence at the time that the dinosaur actually bit into anything living, and some palaeontologists have proposed that it scavenged for its meals. But now, a team has found definitive evidence that the T. 恐龙 did hunt for live prey.
Glacier melt causes large fraction of sea level rise
Time1: 59'' From 2003 to 2009, 259 billion tons of ice have molten
Sponges boom thanks to Antarctic ice shelf bust
Time2: 2'06'' Even life living under cold water can adapt to climate change rapidly.
The solar system has a tail
Time3: 1'45'' scientists proved the tail of solar system exist by IBEX, but don't know how long it is and how it changes
Tyrannosaurus rex hunted for live prey
Time4: 1'37'' A teeth in a bone fossil proved T. rex hunted of living prey
Time5: 1'25'' but there are still some debates about this issue
Natural defences can sharply limit coastal damage
Time6: 5'55'' As hurricanes increased, researchers studied how coastal habitats help to retard damages created by storms;
They ranked 9 habitats; however, two key missing thing are good quality data on habitats and a rigorous way to assess value of nature

Some scientists do some research find that the melting glaciers cause a large fraction of the ocean levels to increase.
1'37''
A research finds that the number of a creature named sponge has been exploded because the melting of the glaciers. This is a surprise finding because this creature often took many years to mature before.
1'36''
The discovery comes from the IBEX that they used data to show that the solar system does indeed have tails, although they do not know exactly the length of the tail now. The scientists use this tail to map the boudaries.
1'28''
A new finding suggests that the T rex dinosaur not only ate carcasses but also ate lively body as well. Unlike the other finding which cannot tell whether the T rex dinorsaur attacked others are lively or dead, this finding definetely suggests that the T dinosaur attacked the hadrosaurs while it sill alived, because the T' teeth in H's tail was get enclosed by H's own tail's borns.

The wound would likely be made through chasing. But some people also said it is hard to determine and there is no need to put too much emphasis on the T dinosaurs.

Natural defences could protect the people and the property from being damaged from hazards such as hurricans. Scientises have researched which kind of defense is most effective in protecting through creating a model. But there are also something we could do to modify and perfect the effect of the natural defences.
52“ the glacier and ice sheet losses explain large fraction of sea level rise
1'10" the change of marine life diversity
1'23" the solar system was first time found its clover-shape tail 这篇无比茫然。。。太阳系有尾巴，什么是tail。。。
1'50" a new finding that tooth of t.rex is stuck in one dinosaur's tail which implies that t.rex might hunt for live prey
1'23" the research team thought the tooth told everything and other scholars thought this topic wasn't worth so much attention
4'15" 1. tells the importances of natural coastal habitats for costal protection
introduces the study plans to defend coastal
their methods to rank habitats and the use of the studies
科技文读的好慢，不过main idea都很清晰。PPX谢谢！

Sea level rise because of the melting glacier of non-polar ice sheets.

The boom of the glass sponges shows that sea life may adapt rapidly to climate change.

The solar system drags a tail as it moves though the galaxy. Description of the finding data, shape, estimated length.
4-271-1'20''
New finding shows that T.rex did hunt for live prey because T's tooth stuck between vertebrae in the tail of prey.
5-242-1'30
Debate of the T: whether they hunt or scavenging ? there is no sufficient evidence for the conclusion
Obstacle-760-4'54''
=>Natural habitats such as coastal forest, coral reefs and wetlands can protect costline from hazards.
=>Study to show the extent that the coastline be protected by the habitats.
=>Introduce a experience model for ranking the habitats.
=>The author aggree that two things are important for the consideration of following research:good-quality data on habitats and rigorous way to cost-compare engineered and natural protections.
