标题: 9.2 730 放狗
考前许愿，如果过700就来回馈CD，没想到超出预期了嘿嘿

主要记得RC了

一、加拿大铁路

二、英国Scarlett姐妹，历史学家对17（18？）世纪女性的生活状况有误解，但是姐妹的书信反驳了这一点：即使是婚后，她们也联系密切，分享政治观点，参与彼此的文学创作。
第二段，当时的中层高层女性有一定的政治影响力（非正式的）。

三、很长的一篇。一屏半吧....印度发现了一个A语言，认为和佛教有关，源于B语言。
第二段，这个地方处于各种文化的交流地带，各种语言都对他有影响，所以专家相信，即使现在只有一份文字资料，一定还有别的。
第三段，发现了一份很古老的手抄资料，材质不能保存很久，说明这个文化有专人一直对这些资料进行翻录

四、实验。蝙蝠对一种毒蛾害怕，另一种蛾子模仿它，蝙蝠也害怕。
第二段：实验一、毒蛾B模仿毒蛾A，蝙蝠害怕
实验二、无毒蛾C模仿毒蛾A，蝙蝠害怕
第三段：有两种模仿模式

Moths mimic 'Don't eat me' sounds
BY SUSAN MILIUS

另有一篇新的说tigermoth(一种蛾）unpalatable(味道不好的)to bats。bats会捕食moth，tigermoth通过clicking来提醒幼虫，通过什么方式（生词太多看不懂，猜测是指放出毒素的意思）来躲避bats。而其他种类moth(应该是对bats没有毒）则会模仿这种click来躲避bats，这种现象被称为defensive mimic

Some moths defend themselves from hungry bats by mimicking the sounds of other, bad-tasting moths, according to new tests. This trick represents the first confirmed acoustic example of classic defensive mimicry.

The study's unpalatable moths, members of the tiger moth family, pick up noxious chemicals from plants that they feed on as caterpillars. A bat unwise enough to catch one of these moths typically spits it out fast.

When a bat swoops near, tiger moths make bursts of "click-click-click" sounds. A young bat hearing clicks and then snagging a vile mouthful learns to avoid the moths, according to earlier work by William E. Conner at Wake Forest University in Winston-Salem, N.C.

To see whether other moths could protect themselves by mimicking those clicks, Jesse Barber, also at Wake Forest, raised bats from babyhood in large, netted enclosures where he could control when they first encountered various prey.

第二段就说某个人进行了 2个实验第一个就是将tiger moth从小就喂养然后和10只bat 放一起 5天过后所有moth都可以骗过bat吧这个人又换了一种moth和tigermoth特点一样的发现刚放进去的时候这种moth不能骗过bat 但过段时间大多数都能第二个实验是将另外一种和tigermoth 特点不一样的moth放来和bat一起发现这种moth 是通过模仿对bat有害的或者bat觉得不美味的动物的声音来避免被捕食的

At some point, he included clicking, unpalatable tiger moths among the nightly flying snacks. After 5 nights, all the bats had learned to avoid this species. Then Barber substituted a different tiger moth species. A few bats sampled the newcomers before avoiding them, but the majority avoided them from the outset.

In another experiment, Barber offered milkweed tussock moths to 10 bats. These moths click, but they’re palatable. Three bats discovered that the new moths were edible, but the other seven didn’t catch on.

That means clicking works both a Müllerian mimicry (two unpalatable species benefiting by making similar sounds that predators can learn by catching either one) and Batesian mimicry (edible prey borrowing an “unpalatable” signal), says Barber.
