  参考答案

  61.C)。

此题考查地球温度上升带来的变化。

定位句提到“地球温度每上升l.8华氏度(1摄氏度),那么大西洋中强度可匹敌甚至胜过卡特里娜飓风的飓风数量会增加两倍乃至七倍”,故C)“更多像卡特里娜那样或是更糟糕的飓风”为答案。

  62.D)。

此题考查对飓风形成的区域中海水情况的理解。

定位句提到“从海洋中蒸发到空气中的水分越多,那么飓风的威力就越强,然后会直扑陆地”,故D)“蒸发成水蒸气,使得风暴威力增强”为答案。

  68.B)。

此题考查飓风卡特里娜的细节。

定位句提到“卡特里娜飓风在抵达新奥尔良州之前威力大增,其宏大的破坏力致使200余人丧生,并造成了800亿美元的经济损失”,故答案为B)。

  64.A)。

此题考查局域海面温度的变化对飓风造成的影响。

根据定位句,局域海面温度的变

  化是飓风变化的主要原因,故答案为A)。

  65.B)。

由倒数第二段最后一句和最后一段的第一句可知,全球变暖是由温室气体大量排放引起的,而全球变暖和破坏性风暴频率变高之间存在联系,由此可推知,减少温室气体排放,或可缓解全球变暖的趋势,从而减少破坏性风暴的发生频率,故答案为B)。

  参考答案

  56.A)。

此题考查“自我的一代”“千禧年一代”的区别。

由定位句可知,“自我的一代”与他们的千禧年一代的哥哥姐姐们相比,更愿意持续不断地与他人保持联系,也希望随时能让别人找得到他们。

由此可推断,他们愿意通过高科技手段与他人随时保持联系,因此A)是此题答案。

  57.B)。

此题考查罗森将新的一代命名为“自我的一代”的原因。

该段前两句引述拉里罗森介绍“自我的一代”的话,点明了这代人的特点,即高科技是这代人的典型特征,它也是种心态,这种心态随“小我”而变化,即“个性化”也是鲜明特点,表现为每件事都为“我”而定制,或每件事都被赋予个性化特征。

由此可见,这代人强调个性化的生活,因此B)是此题答案。

  58.D)。

此题考查关于“自我的一代”的论述哪项是正确的。

由该段可知,对这代人而言,便携是关键。

他们离不开无线装备,那些东西可使他们发短信或聊天,可以时刻与他人保持联系。

由此可见。

这一代人离不开无线高科技产品,因此D)是此题答案。

  59.C)。

此题考查科技对“自我的一代”的影响。

由定位句可知,他们本来应该受到干扰,表现应该糟糕.但研究结果说明这些十来岁的孩子比我们通过年龄和大脑发育而做出的预测要有更强的抗干扰能力。

由此可推断,科技并没有对他们的心智开展产生明显的负面影响,因此C)是此题答案。

  60.A)。

由该段可知,由于这代孩子在年幼时便深浸于科技之中,那么教育制度也要随之进展显著改变。

由此可推断,教育制度也应适应这代人,因此A)是此题答案。
