Article 1 Breakthrough on the study of sunburn---inhibit TRPV4 to protect one from UVB exposure. May help promote protection against it with further study on its potential "side-effects".
Article 2 Sunlight's benefits on health ourweigh its risk of developing skin cancer.
Article 3 Brain game vs. Nature documentaries---> The latter helps enhance language skills better. Brain games may not be that effective at boost mental capacity.

Main idea: On contrary to the common knowledge of a schoolchildren, space rocks may be responsible for these huge extinctions. This promising idea still requires further proof and digging.
Attitude: Neutral
Structure:
>>>Novel discovery on the biggest extinction: There's been four massive extinction in the history. The unknown field of this problem is whether these four extinctions had similar causes, such as space rocks.
>>>Where does this idea come from: The dinosaur extinction at the end of【the Cretaceous period】had one similar case---the one that happened at the end of 【Permain period】. The meteorites of the correct age played a larger part in the species's extinction.
>>>One missing puzzle: WHERE is the space rock that you held responsible? Crater evidences missing.
>>>The time of the event: Dr Tohver and his colleagues thought【the Araguainha crater】was the one. Dr Tohver put the event【within geological spitting distance of the extinction date, which itself has a margin of error of plus or minus 200,000 years】, making the evidence authentic and convincing.
>>>The possible cause other than size: But there's a logical problem with his argument----the size of the crater seems too small for that kind of effect. Again, Dr Tohver found his way to answer the criticism. The sizable amount of the rock that created the essential crater in his argument prove to be【oil shale】, which would then cause an earthquake of magnitude 9.9 , then, the oil and gas would be released. Then comes the global warming and the acute climate change. Everything could be explained.
Meteorite-->crater-->earthquake-->huge amount of oil & gas(methane甲烷,沼气)-->global warming-->climate change
>>>Conclusion: The research still needs further digging to prove its authenticity, of course. If the Dr Tohver succeeds in doing that, he would be solving the greatest puzzle in【palaeontology古生物学】.

1、speed参差不齐,time2读得太尽兴把它当成课本在看了,反反复复地在想究竟肿么个发生顺序= =
基本上属于一感兴趣就忘了时间……明天集中精力放在逻辑链上,加快速度。

3、obstacle的速度丧心病狂了……我好像中间看着看着就思路走偏了哈哈哈哈哈【。写回忆还是要更加精炼。 |
