nutrient availability seem to have trumped the benefits of increased carbon dioxide，”said researchers from the national university of singapore.45 percent of the species studied now reach smaller adult sizes than they did in the past.the researchers pointed out that warmer temperatures and changing habitats，caused by climate change，are possible reasons for the shrinking of creatures.“we do not yet know the exact mechanisms(机制)involved，or why some organisms are getting smaller while others are unaffected，”the researchers said.“until we understand more，we could be risking negative consequences that we cant yet quantify.”the change is big in coldblooded animals.only two decades of warmer temperatures are enough to make creatures smaller.an increase of only 1 causes nearly a 10 percent increase in metabolism(新陈代谢)greater use of energy results in tiny tortoises and little lizards.fish are smaller now too.though overfishing has played a part in reducing numbers，experiments show that warmer temperatures also stop fish growing.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，compared 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.语篇导读：研究人员发现，气候变暖会导致地球上许多生物的个头变小。1.what does the text mainly talk about？awhy some species become smaller.bhow climate changes in earths history.cclimate change has many negative effects.dspecies

dlost答案：a解析：词义猜测题。根据画线词所在句中的but可知，画线词所在部分与前面的内容，即大气中二氧化碳的增加将使生物个体变大之间为转折关系，从而可以推测气温、湿度、营养供应等的变化对生物的影响“战胜”了二氧化碳带来的好处。故选a项。3.researchers from the national university of singapore believe that_.athey have found the exact causes for creatures getting smallerbincrease in energy use can lead to creatures getting smallercclimate change has more negative effects on warmblooded animalsdall the animals on the earth have become smaller答案：b解析：细节理解题。依据文章第四段中的“greater use of energy results in tiny tortoises and little lizards”可知，生物体消耗自身的能量越多，其个头就越小。故选b项。4.what does the author feel about the climate

wife”这一倒装结构可知，这里是“so助动词主语”，意为“也是如此”。2.答案：had sunk解析：考查时态。sink这个动作是发生在主句的谓语动词heard之前的，因此用过去完成时表示过去的过去。3.答案：for解析：考查介词。search for为固定搭配，意为“寻找，搜索”。4.答案：daydreaming解析：考查非谓语动词。空处作伴随状语，且与主语he之间是逻辑上的主谓关系，故用daydreaming。5.答案：a解析：考查不定冠词。由语境可知这里表示泛指，要用不定冠词a，a heavy object指“一个重物”。6.答案：excitedly解析：考查副词。修饰动词pulled要用副词，excite是动词，因此要先变为形容词excited，再加ly，变为副词。7.答案：what解析：考查主语从句。空处在此引导主语从句，且在从句中作saw的宾语，故用what。8.答案：there解析：考查there be句型。这里是there be句型，用以表示某处存在某物或某人。9.答案：though解析：考查连词。根据上下文可知，尽管船在不断地下沉，渔夫还是拼命地往船上拉金链，表示“尽管”要用though。10.答案：finally解析：考查副词。分析句子成分可知，空处作状语，因此要用副词形式，故填finally。.短文改错time flies and i wi
