Question

    A small insect is gettinga lot of attention in the United States. The rusty patched bumblebee (大黄蜂) is the first of its species to be declared endangered in the lower 48 states — meaning every state except Alaska and Hawaii. The rusty patched bumblebee is named for a rust-colored line on its back.

The U.S. Fish and Wildlife Service announced this month it was adding the bee to its endangered species list. The insects are "on the brink of extinction, " according to the service. It said the bees were once found in 28 states. But there now are only small populations remaining in 13 states. The government agency will make a plan to help the dying bees recover. The agency said that such a plan might help other insects,like butterflies.

U.S. officials think land owners can take small steps to help the rusty patched bumblebee. They say land owners can be friendlier towards bees by using native plants in their gardens. The insects directly fertilize many kinds of fruit and vegetable crops. And they fertilize grain crops used to feed cattle and milk cows. It costs billions of dollars to duplicate the job the bees do for free. Land owners are also being urged to cut back on their use of pesticide products. The officials also suggest that gardeners leave their plants alone at the end of the summer instead of cutting them. That way, the bees will have a place to live over the winter.

The Fish and Wildlife Service says the rusty patched bumblebee was added to the endangered species list partly because of habitat loss. Other reasons were disease, pesticides and climate change. Officials are worried that other bees will suffer, too. Another species of bees in Hawaii is also endangered.

【解析】

本文是说明文。文章阐明了在美国濒临灭绝的锈迹大黄蜂的情况，以及采取保护措施，并说明了灭绝的原因。

1.细节理解题。根据第一段中的The rusty patched bumblebee (大黄蜂) is the first of its species to be declared endangered in the lower 48 states — meaning every state except Alaska and Hawaii.可知，锈迹大黄蜂是48个州中第一个被宣布濒临灭绝的物种，这意味着除了阿拉斯加和夏威夷以外的每一个州都是如此。由此可知，有48个州宣布锈迹大黄蜂濒临灭绝。故选C。

2.推理判断题。根据第三段中的The officials also suggest that gardeners leave their plants alone at the end of the summer instead of cutting them. That way, the bees will have a place to live over the winter.可知，官员们还建议园丁们在夏末的时候不要去修剪它们，而是让它们自己生长。这样，蜜蜂就有地方过冬了。由此推知，定期剪植物对锈迹大黄蜂是有害的。故选D。

3.推理判断题。根据第三段中的The insects directly fertilize many kinds of fruit and vegetable crops. And they fertilize grain crops used to feed cattle and milk cows. It costs billions of dollars to duplicate the job the bees do for free.可知，这些昆虫直接给许多水果和蔬菜作物施肥，它们还为喂牛和奶牛的谷物施肥，复制蜜蜂这些免费的工作要花费数十亿美元。由此推知，锈迹大黄蜂对土地的主人是有益的。故选C。

4.主旨大意题。根据最后一段第一句The Fish and Wildlife Service says the rusty patched bumblebee was added to the endangered species list partly because of habitat loss.可知，鱼类和野生动物管理局说锈迹大黄蜂被列入濒危物种名单，部分原因是栖息地丧失。由此可知，Bumblebee added to U.S. endangered species list(大黄蜂加入了美国濒危物种名单)适合做本文最佳标题。故选A。
