Now, he works for non-profitable organizations and serves as a consultant for energy efficiency. ”可知 C 项正确。由第三段的“ Davis wasn't a born environmentalist. ”可知 A 项“ long-time dream of… ”不正确；由该段 Davis 为环保所作的一切可知他不为自己曾经的决定后悔， B 项不对； D 项中的原因不对。

2. C 。第五段“ … Davis made me know how important it is to be a smart consumer, by supporting organic ( 有机的 ) food and green products instead of only looking at the brands. ”详细说明了什么是“ Shopping with a moral in mind ”，因此 C 项为最佳选项。

2. C 。由第七、八段可知 2000 年前李连杰出演的片子情节比较简单可预测，武打动作使用广泛，但是由于他英文不好，他扮演的角色通常台词不多。由第九段“ Li started to make changes to this problem in 2000. He starred in Hero, exploring a philosophical ( 哲学的 ) story of mercy and courage. In his winning work, The Warlords, Li captures the inner-struggle of an ambitious army general, adding a tragic touch to the whole picture. ”可知， C 项是他 2000 年后改变之后所演角色的特点。故 C 项符合题意。

1. B 。本文主要是讲了空气污染使得芳香减少，从而影响了蜜蜂等昆虫的生活，使它们数量大量减少，因此 B 项为最佳选项。

2. C 。由文章第二节 Bad news for bees? 的第 3-5 段 But he says he hasn't seen bee behavior that suggests trouble with scents. “Over the last couple of summers I don't think the bees in this area were bringing in much less food,” he said. “ It might be that they had to work harder, but it seems like as long as there were bees to collect food they were finding flowers somewhere. ”可知 Jay Evans 认为花的芳香减少对蜜蜂的影响并没有想象中的那么大，故 C 项正确。

3. A 。文章最后三段是 Fuentes 的观点，倒数第三段 But Fuentes fears that the fading smell of flowers may stress insects that are already faced with other threats. 中的 stress 与下文的 exacerbate 在文中意义相近，意思为“加重，使压力更大，使情况更遭”，因此选 A 。

4. D 。由第 7-9 段“ With more pollution in the air, the scent molecules don't remain potent as long and travel shorter distances on the wind... ”可知空气污染影响花香传播的远近，污染越重，传播越近，因此 A 、 C 正确；由文章第二节 Bad news for bees? 的第 2 段“ Scientists trying to find the cause of bee population declines have blamed bacteria, pesticides, and even cellphone radiation. ”可知 B 项也正确； D 项似是而非，文中提到了“ The trend is unpleasant for human noses, but may be life-threatening for bees and butterflies. ”说明花香减少对人类的影响要小于对昆虫，但并没有提到空气污染对谁的影响更大，因此 D 项符合题意。

3. C 。文章最后提到了 “ Santa was alive and well, and we were on his team. ”作者并不是指世界上真有 Santa ，作者的意思是，象他这样冒充圣诞老人给同学悄悄地送圣诞礼物，圣诞老人就在身边，因此 C 项为最佳选项。
