1-0'48 studies proves that bees prefer caffine more and can remember the ordor for 24 hours, further experiments will be made on whether they will ignore their predators to get the caffine
2-1'19 something about the deep channel deep beneath the surface of the earth.
3-1'46
some scientists suggest that lions should be kept in fence to protect them from extinction, their number decreases sharply these years and they often attack cows,but it is very expensive to build a fence for lions
4-1'41 more ways to protect lions are mentioned here, one is to keep them unfence in the park, but it costs more and protect less lions then fencing them, the other way is to keep them in a buffer seperate from human, but it also costs a lot
5-1'34 tropical forests are more robust than expected, it may survive from many bad climate.
obstacle
4'31 women is still in lower position over men in scientific major, they are less supported, they earn less, and they want less children than their male college, though there are a lot of unaffairs to women, but those who loves science will never give up
structure: the passage firstly tells us that there are still a lot of inequalty in the scientific major, then it describes the inequalty in 3 aspects to show where they are.
1.1.14 a research associated with honey bee。 2.1.20 the depth of the channel on the marz is deeper than analysis previous thought。 3.2.25 the number of lions is decreasing and fence is needed to protect lions which costs a lot。it is really a big puzzle to realize protection lions and save money at the same time。recently，researchers suggest a co-author method to resolve both side of the puzzle。 4.忘计时了，悲催 reservation cost less than then fenced。but due to humans pressure，the cost of reservation will not decrease。so it is necessary to find new way to protect lions。 5.2.59 in contrast with previous view，the new report suggests that the tropical forests will not vanish because of the greenhouse。
obstacle-5.35 the article talks about a phenomenon in the science field that consists of only a few women。the resons for the phenomenon are lack of role model， family value and pay gap between men and women。
thx for sharing!!!!辛苦啦! 0.59" honey bee remember the plant through the CN. 1.24" some researches on the recently carved channel system on Mars??(read twice and still find it hard to understand) 2.07" a study suggested that lions should be protected, but the cost of protecting lions is expensive. Packers found a cheaper way. 2.05" fencing the lions cost much less than building a buffer zone or a reservation and it's also better for the lions to be fenced. 2.08" Recently study shows that climate change will not result in the loss of rainforest. Though there are robust rainforests, uncertain remains. 5.10" Gender bias resulted in the less proportion of women scientists.And this maily because women dropped their scientific career early, which is related to the family value and the paymen ineuality.
1 01:20 [173] Researchers find that bees can remeber the plant they previously went by the scent of the plant. This might be the caffine nectar that affects the bees' neuron and brain.
2 01:45 [247] By studying Mar's pictures, scientists find that a carved channel on Mar is much deeper than previously thought. The channel was once formed by lava and there was water flood. It might be the same as Earth's deepest channel.
3 02:30 [358] A study about lions reveals that lions can be most effectively protected by putting fence around their living region. Some scientists question this method, and the projects is very expensive. But other places that have already use fence proved that the number of lions recovered to previously level.
4 02:27 [346] The benefits of fence including help population of lions increase, decrease costs for protecting against illeagal kill, etc. Another sicientists propose to establish buffer zones to segerate humans from lions, but this is not feasible in many situitions. So fence might be required as infrasturcture for reserves in the future.
5 02:10 [376] A study concludes that tropic rain forests will not die out by green gas and global warming. The predication is made by a model created by UK university, but latest study and new data showed the forest will not endure drought and can tolerate such change. Different models have different results.
6 06:03 [967] Main Point: Discuss the reason why women are much less likely to pursue an acdemic life.
Structure: Current situation: much less women have a doctor degree and even less become professionals in engineering and science study -- Analysis: more women give up the idea of pursuing a academic life -- Reasons: family, confliction with chideren bearing; payment gap, women are generally paid less than men in such fields -- Solution: some universities provide policies helping young faculties to take care of family, but there more steps needed to slove this problem
1.1'12'' 2.2'01'' 3.2'16'' 4.1'44 5.2'02'' 6. 6'09'' sexual inequality exists in academic area. Less female can persistantly pursue academic career. Sexism still exists in today's university. To better pursue family value, more female give up their academic career than male. And Female get lower paid. But in recent years, sexual inequality problem are paid attentions and universities are trying to short this gap between male and female.
