分析 這篇文章講的是通過Paul Nicklen這個攝影記者在北極拍攝照片時一次偶遇北極熊脫險的經(jīng)歷,揭示了在全球變暖的情況下,北極熊的生存環(huán)境受到了極大威脅,由于浮冰的減少,北極熊很難找到食物,尤其是它們最喜歡的食物海豹.沒有充足的食物,北極熊的數(shù)量在急劇減少,在不久的將來大部分北極熊會從地球上消失.所以保護環(huán)境,阻止全球氣候變暖是拯救北極熊的當(dāng)務(wù)之急.
解答 76.C.主旨大意題.根據(jù)關(guān)鍵句In the future,polar ice will continue to shrink and endanger the bear.Some scientists believe 65percent of the world's polar bears will disappear by 2050.In other word,polar bears are in great danger.及聯(lián)系整篇文章的內(nèi)容主要講了全球變暖對北極熊形成的威脅,故選C.
77.C.細(xì)節(jié)理解題.根據(jù)The polar bear wasn't so lucky.It couldn't get a meal,可知這個北極熊非常不幸運因為它吃不著這頓美餐.故選C.
78.A.細(xì)節(jié)理解題.根據(jù)They stand on the ice wait for the seal to come up for air.可知它們站在冰上等待海豹出來呼吸時發(fā)起攻擊.故選A.
79.B.推理判斷題.根據(jù)He was there to take pictures for National Geographic.可知他在那兒為《國家地理》雜志拍攝照片.所以他可能是一名攝影師.故選B.
80.C.推理判斷題.根據(jù)As Arctic ice melts,polar bears have to swim farther to find ice floes,or large pieces of floating ice.Sometimes,bears have to swim more than 200km to find an ice floe.Some bears cannot swim that far and sadly they drown.等描述可以推斷出由于地球變暖,浮冰消失,北極熊不能很容易的找到食物,故選C.
點評 本題考查健康環(huán)保類閱讀理解.解答此類題,關(guān)鍵是要善于捕捉有關(guān)問題的信息,然后在透徹理解原文的字面意義和題意的基礎(chǔ)上,結(jié)合題目對其進行分析、推理,判斷,從而得出正確的結(jié)論及答案.
