三、阅读理解
Blue whales, the earth's largest animals, call to others of their kind, though exactly what these cries communicate remains a mystery. But these sounds have begun evolving (逐渐演变). Since at least the 1960s, the pitch (音高) of Antarctic blue whales has downshifted. Scientists have theories as to why: all involving humans.
The deepening of their sounds is not unique. Many blue whales around the world have also dropped their pitch. In the study last year that analyzed more than 1 million individual recordings of whale calls, pitch shifts were found across the species, and among populations (种群) that don't necessarily interact with one another. This is to say, whatever has caused the change doesn't seem to have a specific geographic origin.
The underwater noises caused by ocean traffic and at-sea industries might seem likely criminals. However, scientists have identified lowered pitch even across populations of whales that live in seas without major shipping routes.
One possible explanation for the change is the achievements of global conservation efforts. As their populations grow, the whales may have decreased their volume because they are more likely to be communicating over short distances.
Last year's study of whale calls also suggests a threatening reason for the drop in pitch, however. Perhaps whales don't need to be so loud because sound waves travel farther in oceans made acidic by the absorption of carbon dioxide.
Carbon dioxide in the atmosphere, meanwhile, may also indirectly influence whale voices in other ways. A recent study shows that, during the summer, the whales must use their top volume to make themselves heard in the cracking ice — a natural sound increased by unnatural processes, as rising temperatures worsen ice-melt. So the impacts of a warming planet may modulate animal sounds even in remote places.
1.To what extent does whales' pitch drop
A.Across the species. B.In the Antarctic Ocean.
C.Among some populations. D.Within one million individual recordings.
2.What causes the evolving of whales' pitch according to the text
A.Less communication and more threat. B.Protection efforts and acidic sea water.
C.Sharp decrease of whales' populations. D.Underwater noises by ships and industries.
3.What does the underlined word "modulate" mean in the last paragraph
A.Produce. B.Damage. C.Balance. D.Change.
4.What can we infer from the text
A.Man is the soul of nature. B.Man and nature are in one.
C.Nature pardons no mistakes. D.Nature has the final say over man.
四、语法填空
Last night's fall of snow here was not only an event but a magical event because it is the first fall we ①__________(have) here this winter. When I got up this morning, I was excited to find what ②__________ extraordinary change it was just overnight!
The world was a cold place of dead white and pale blues. The light that came through the windows was very strange, and the familiar business ③__________(make) very strange too. Then the sun came out, ④__________ light was flushing the snow with delicate pinks and had changed the dining-room window ⑤__________ a lovely Japanese print. The little plum tree outside, with the faintly flushed snow lining its branches and artfully ⑥__________(dispose) along its trunk, stood in full sunlight.
An hour or two later everything was a cold sparkle of white and blue. The world had completely changed again. The ground extended far, the sky was dim, and all the trees were so many black and threatening ⑦__________(shape). There was indeed something curiously disturbing about the whole prospect.
Now it has changed again. The snow is falling so ⑧__________(heavy) that you can hardly see across the shallow valley. The roofs are thick and the trees are all bending, and the weathercock of the village church, still ⑨__________(see) through the grey loaded air, has become some creature out of Hans Andersen. From my study, I can see the children ⑩__________(flatten) their noses against the window.
答案以及解析
一、
1.答案：innocent
2.答案：enhance
3.答案：bending
4.答案：rhyme
5.答案：church
二、答案：1.early on 2.at the risk of 3.came out 4.broke out 5.talk away 6.woke up 7.is famous for 8.a number of
三、答案：1-4.ABDB
解析：1.考查细节理解。 由第二段中的"In the study last year... don't necessarily interact with one another"可知,去年一项分析了超过一百万条鲸鱼叫声录音的研究发现,音调变化现象遍及整个物种中,也存在于那些之间并没有必要沟通的种群中。故选A。
2.考查细节理解。由第四段中的"One possible explanation... global conservation efforts"和第五段中的"Perhaps whales don't need... by the absorption of carbon dioxide"可知,全球保护行动以及酸性海水是鲸鱼声调变化的两个原因。故选B。
3.考查词义猜测。文章主要讲述了鲸鱼叫声音调改变的几个原因。 最后一段讲了全球变暖导致冰融化同样也是动物声调变化的原因。由此可推断modulate是改变的意思。故选D。
4.考查推理判断。文章讲述了鲸鱼叫声音调改变的几个原因,而所有的原因均与人类有关,不管是人类的保护行动,还是人类活动导致的全球变暖对动物均有影响。因此人类和自然并非是相互独立的,而是相互依存的。故选B。
四、答案：have had; an; was made; whose; into; disposed; shapes; heavily; to be seen; flattening
解析：①考查动词时态。在句型"it is the first/ second/... that..."中,that从句使用现在完成时,故填have had。
②考查冠词。分析句子结构可知,此处为感叹句"what +a(n) + adj. + n. +主语+谓语"。change为名词,表示泛指,且extraordinary的发音以元音音素开头,故填an。
③考查动词的时态、语态。主语the familiar business和谓语make之间是被动关系,且根据句意可知,应使用一般过去时,故填was made。
④考查定语从句。分析句子结构可知,空处引导非限制性定语从句,修饰先行词the sun,故用whose指代先行词,作定语,并和light构成所属关系。
⑤考查介词。change…into... 是固定短语,意为“把……变为……”,故填into。
⑥考查非谓语动词。此处为with复合结构,宾语the faintly flushed snow和动词dispose是逻辑上的动宾关系,故填过去分词表示被动。
⑦考查名词复数。shape在此作可数名词,并根据之前的many可知,应使用名词复数形式shape。
⑧考查副词。修饰动词应用副词,故填heavily。
⑨考查非谓语动词。分析句子结构可知,and后的并列句中,已有谓语has become, still... air应是非谓语结构作定语修饰主语weathercock,且主语和see构成逻辑上的动宾关系,表示将来的动作,故填to be seen。
⑩考查非谓语动词。see sb. doing sth.意为“看到某人正在做某事”,故填现在分词flattening作宾语补足语。
