2、ations 40 years ago.Monarch butterflies have two populations：eastern and western varieties separated by the Rocky Mountains.The populations are very similar in appearance, but western monarch butterflies are generally smaller and darker in color.The two also follow different migration (迁徙) patterns.
3、Eastern monarch butterflies spend winter in Mexico, while western ones gather on central California coasts to wait out the cold.In early spring, the two leave their rest places and begin to travel eastward.By the time the butterflies reach the Central Valley, they breed (繁殖)A butterfly can lay hundr

Just five months earlier he had finished college, where he studied biology and environmental science.As the ship entered nutrientrich Antarctic waters, whales suddenly showed up all around
15、 the ship. That moment on the bridge helped him realize that the ocean looks featureless from the top, but theres so much going on underneath.The second lightbulb moment hit him several months later.

30、fish.GThere are some things that may help slow warming trends and save polar bears.语篇解读：本文是一篇说明文。因为人类活动，北极熊已经失去了大部分的栖息地。文章说明保护北极熊的重要性及措施。1选C根据空后一句可知，空处内容应是有关北极熊失去的东西的。“And”和“also”表明设空处与空后是并列关系。故C项“因为人类活动，它们已经失去了大部分的栖息地”符合语境。2选A根据空后一句及后面的举例可知，任何一个物种的缺失都可能会引起严重的后果。故A项“生态系统高度依赖于它的所有部分”符合语境。3选D根据空前一句及空后
31、内容可知，所有的捕食者都在自己所生存的领域中扮演着重要角色，一旦失去它们，会导致很多问题的出现。故该空承上启下，说明的应是捕食者所扮演的重要角色，故D项“他们能帮助调节和控制其他物种的数量”符合语境。4选F根据空前一句及空后的内容可知，海豹数量的激增会导致鱼类数量的减少，会给人类带来直接影响，F项(人类可能会与海豹竞争食物鱼类)直接承接上文“a direct effect on humans”，并与下文最终影响人类的食物供应和渔业的发展衔接自然。故F项符合语境。5选G根据空后一句可知，本段主要说明的是保护北极熊的措施。故G项“有一些事情可能有助于减缓(气候)变暖的趋势，拯救北极熊”符合语境。空
