2-D组成成分是否相同和这个坑到底是火山遗迹还是流星撞击无关 无论成分是否一致 都没法告诉我们怎么区分到底是火山遗址还是流星撞击 但是B如果这个流星撞击的残余是洋流带过来的话 那还是有可能是火山遗址的 （有帮助我们判断是A还是B所以正确）

1. [Strength C2 / Weaken C1] A
C1 pink color<---microorganisms; water <---increase in global warming, an increase that has been occurring for just a few hundred years.
C2 C! is wrong!
P1 ice = insulator, trap heat emanating from the earth ---> water |ice|+++ for thousands of years + P2: ? A
[思路: 一个是排除全球变暖这个原因，另一个排除几百年这个说法]
2. [Evaluation] A ❌ B
P A=remnant of a volcano X； evidence of a meteor impact: meteor fragments&glass droplets&various chemical elements from outer space
C the crater was instead probably formed by a meteor impact. 日常错题搬解析：
F:科学家一直认为A的一个火山又地形是火山遗迹。 但最近对最底下的一层沉 积物分析，发现流星撞击的证据:流星碎片，撞击形成的玻璃滴及可能来自外 太空的各种化学元素
C:说明该坑很可能是陨石撞击形成的 Q: 评价
思路:
该坑是否由陨石撞击形成的 作者假设:该坑物质(证据)是撞击留下的还是其他地方通过海水漂流过来的 方向: 考场上选残余物是否被洋流带到此地的选项
正确答案B: 流星撞击的残余物是否会被洋流带到该地。

1. A
Researchers studying the Greenland ice shelf were shocked to discover the presence of water, colored pink, two miles under the ice --> They concluded that the pink color was probably due to microorganisms -->They also concluded that the water was likely due to a drastic increase in global warming, an increase that has been occurring for just a few hundred years
It is just as possible that the water has accumulated under the ice for thousands of years, since the ice could have acted as a perfect insulator to trap heat emanating from the earth
2.
Evaluation: D
P: recent analysis of one of its lowest (and therefore oldest) layers of sediments found evidence of a meteor impact: meteor fragments, glass droplets of the sort formed during meteor impacts, and various chemical elements that most likely came from outer space
C: crater was instead probably formed by a meteor impact.

B -- 流星撞击的残余物是否会被洋流带到该地。
Yes， 残余被带到这里， 坑还是火山形成的。
No,  残余是由流行撞击而留下的， 坑也是流星撞击形成的。
