But that could change as their fish 3 (supply) move further into the Southern Ocean, where there is only a 4 (hand) of islands to provide a home for the birds.

King penguins require remote islands 5 are not too cold, have no winter sea ice and no fierce animals. If they have to swim more than 435 miles on 6 round trip to hunt for fish, their waiting children can starve to death as their fat reserves become steadily 7 (few). It can take a parent three months 8 (deliver) fish to its young.

【解析】

这是一篇说明文。根据最近的一项调查,超过70%的帝企鹅可能被上升的海洋温度消灭。随着它们赖以生存的鱼类供应进一步进入南大洋,情况可能会发生变化。鱼类种群向南迁徙的影响可能导致企鹅种群大量减少。

1考查被动语态。分析句子可知,设空处和could一起构成句子谓语动词,主语king penguinswipe out之间是被动关系,应用被动语态,又情态动词could后要用动词原形,故填be wiped

2考查副词。句意:然而,很多人都很乐观,因为这些统计数据显示这些企鹅目前还没有濒临灭绝,根据句意可知,上下文是转折关系,故填However

3考查名词的数。分析句子可知,此处应用名词作为句子主语,因为句子为一般现在时,故由谓语动词move判断主语是复数形式,fish supplies“鱼类供给”,故填supplies

4考查名词。句意:但这种情况可能会改变,因为它们的鱼类供应进一步进入南大洋,那里只有少数几个岛屿可以为鸟类提供栖息地。此处考查固定表达a handful of“少数”,handful“一把(的量)”,故填handful

5考查定语从句。分析句子可知,此处是定语从句关系词,先行词islands在从句中充当主语,应用关系代词,故填that/ which

6考查冠词。句意:如果它们寻找鱼类时,一个往返不得不游上超过435英里,它们等待食物的幼鸟就会饿死,因为它们的脂肪储存会变得越来越少。trip是可数名词,结合上下文可知,此处意为“一次往返(的旅行)”,是泛指,应用不定冠词,且round是辅音音素开头,故填a

7考查形容词。分析句子可知,此处应用形容词作为表语,再结合句意可知,此处意为“越来越少”,应用比较级,故填fewer

8考查固定句型。此处考查固定句型it take sb some time to do sth.“做某事花费某人多少时间”,其中it是形式主语,不定式是真正的主语,故填to deliver

9考查时态和语态。分析句子可知,此处是定语从句的谓语动词,主语studypublish之间是被动关系,再由so far判断为现在完成时,故应用现在完成时的被动语态,主语study是第三人称单数,故填has been published

10考查介词。句意:法国斯特拉斯堡大学的科学家们的研究已经发表在《自然气候变化》杂志上,他们警告说,鱼类向南迁徙的影响可能会导致企鹅的大量减少。此处考查固定短语give rise to“引起,导致”,故填to

I was lucky enough to see the flowering desert, a natural scene that 2 (occur) around every five years here in the Atacama Desert.

3 (follow) a particularly large amount of rainfall earlier, a(n) 4(vary) of flowers come into blossom. Bright purple flowers create 5 unbelievably beautiful scene at the base of the surrounding mountains.
