Warmblooded animals arent immune (免除) from the size change caused by climate change.Many birds are now smaller.Red deer are weaker.And polar bears are smaller，pared with historical records. This isnt the first time that has happened in Earths history.55 million years ago，a warming event similar to the current climate change caused bees，spiders and ants to shrink by 50 to 75 percent over several thousand years.That event happened over a longer time than the current climate change. The speed of modern climate change could mean organisms may not respond or adapt quickly enough，especially those with long generation times.So，it is likely that more negative influences of climate change will be shown in the future. 語篇導(dǎo)讀：研究人員發(fā)現(xiàn)，氣候變暖會導(dǎo)致地球上許多生物的個頭變小。 1.What does the text mainly talk about？ A．Why some species bee smaller. B．How climate changes in Earths history. C．Climate change has many negative effects. D．Species are being smaller as climate gets warmer. 答案：D　解析：主旨大意題。通讀全文可知，本文主要介紹了氣候變暖導(dǎo)致許多生物個頭變小這一現(xiàn)象。故選D項。 2.The underlined word“trumped”in Paragraph 1 probably means“________”． A．beaten B．gained C．destroyed D．lost 答案：A　解析：詞義猜測題。根據(jù)畫線詞所在句中的but可知，畫線詞所在部分與前面的內(nèi)容，即大氣中二氧化碳的增加將使生物個體變大之間為轉(zhuǎn)折關(guān)系，從而可以推測氣溫、濕度、營養(yǎng)供應(yīng)等的變化對生物的影響“戰(zhàn)勝”了二氧化碳帶來的好處。故選A項。 3.Researchers from the National University of Singapore believe that________. A．they have found the exact causes for creatures getting smaller B．increase in energy use can lead to creatures getting smaller C．climate change has more negative effects on warmblooded animals D．a(chǎn)ll the animals on the earth have bee smaller 答案：B　解析：細(xì)節(jié)理解題。依據(jù)文章第四段中的“Greater use of energy results in tiny tortoises and little lizards”可知，生物體消耗自身的能量越多，其個頭就越小。故選B項。 4.What does the author feel about the climate change？ A．Worried. B．Optimistic. C．Disappointed. D．Shameful. 答案：A　解析：觀點態(tài)度題。根據(jù)文章最后一句的“So，it is likely that more negative influences of climate change will be shown in the future”可知，作者對氣候變暖這一現(xiàn)象有些擔(dān)憂。 Ⅳ.完形填空 (xx山西太原五中高三測試) Once upon a time in a land far far away，there was a__1__old man who loved everything.
