第二节 外刊视野 请认真阅读下面短文，从短文后所给的六个选项中选出五个可以填入空白处的最佳选项。
Scientists are using satellites(人造卫星) to count Antarctic krill(南极磷虾) from space. These tiny creatures are just six centimetres long and look a bit like prawns(明虾), but they are more important. 41.
Scientists need to watch and count krill so they can check the health of the places where these animals live. However, in the Southern Ocean, where they live, there are more than 700 trillion adult Antarctic krill. That's like trying to count all the stars you see at night!
42. Even if we have special cameras and computers to help.
43. They study the colour of sea water from space. The amount of light the ocean absorbs changes depending on how many krill are in it. Dr Cait McCarry, from the University of Strathclyde, said, "We start with sea water. Then we add a krill and take a measurement (测量) of how much light the water takes in. 44. "
By comparing pictures taken by satellites, scientists will be able to guess how many krill live in different ocean areas. 45. This will also show how they're spread across different areas and how climate change and fishing affect them.
(素材选自 *The Week Junior Science + Nature*)
A. So finding ways to count them all is a super hard task.
B. Then we add another krill and take another measurement.
C. They are food for lots of larger sea animals such as whales.
D. Now, scientists are developing a new method for finding krill.
E. Scientists find that more krill in the water make the ocean look darker.
F. This will give them a better idea of total krill numbers in the Southern Ocean.

第Ⅱ卷(非选择题 共60分)
答案：第二节[语篇解读] 本文主要介绍科学家利用卫星从太空监测并统计南极磷虾数量，以此了解其生存状况。
41. C 根据前句“These tiny creatures are just six centimetres long and look a bit like prawns, but they are more important.”可知，后句需要解释为什么重要。选项C“它们是很多大型海洋动物(如鲸鱼)的食物。”符合语境。
42. A 根据前句“That's like trying to count all the stars you see at night!”和后句“Even if we have special cameras and computers to help.”可知，南极磷虾数量极多，数它们就像数夜空中所有星星一样，即使有相机和电脑帮忙也很难。选项A“所以找到数清它们的方法是一项超级困难的任务。”承上启下。
43. D 上段讲数磷虾很难；本段开始讲具体方法：从太空研究海水颜色。选项D“现在，科学家们正在研发一种新方法来寻找磷虾。”作为段落总起句最合适。
44. B 根据前句“We start with sea water. Then we add a krill...”可知，选项B“然后我们再加一只磷虾，再进行一次测量。”与之对应，是实验步骤的顺承。
45. F 根据前句“By comparing pictures taken by satellites, scientists will be able to guess how many krill live in different ocean areas.”可知，选项F中的This指代前句中提到的方法，同时后句与选项F“这将让他们更清楚南大洋磷虾的总数量。”形成并列。
41. C 根据前句“These tiny creatures are just six centimetres long and look a bit like prawns, but they are more important.”可知，后句需要解释为什么重要。选项C“它们是很多大型海洋动物(如鲸鱼)的食物。”符合语境。
