　　主餐一道：泛听练习
以下段落是摘自新闻里的一些重要信息,并不是一个段落的听写。空内信息可在本新闻中全部找到,大家可以根据这些信息复述新闻。
一、泛听建议：
1、完整听一遍，掌握大意。
2、继续听，特别注意关键信息。遇到相似的词，写下来。
3、复述新闻。
Honda is recalling more than 180,000 vehicles in the U.S. because of _1_ problems. The recall involves certain models built between 2004 and 2006, including two Acura models and Honda Pilot. The Japanese carmaker says mis-wired electronics can cause the cars to brake unexpectedly. No crashes _2_ as a result of the defect.
由于刹车系统存在隐患，本田将从美国召回超过18万辆车。此次将召回2004年至2006年生产的特定车型，包括两款“讴歌”车型及“本田Pilot ”。日本汽车制造商本田表示，由于电子零件安装不当，车辆可能发生突然制动的情况。目前还没有因该故障造成的伤亡报告。
The population of Monarch¹ butterflies is falling to record lows. NPR's Scott Neuman reports some scientists suspect genetically³ modified crops could be a factor.
黑脉金斑蝶的数量降至历史最低点。据NPR新闻的斯科特·纽曼报道，一些科学家认为转基因作物可能是其中一个影响因素。
The butterflies seen each spring and summer in many parts of the U.S., spend their winters in central Mexico, where they cover vast stretches of forest. But over the last several years, scientists in Mexico _3_ a disturbing trend. The wintering butterflies that used to cover up to 50 square acres on their annual migration⁴, now occupy fewer than 3 acres of forest. Scientists think logging in the Monarch,Mexican habitat, has something to do it. But they also point to the heavy use of genetically modified corn and soy beans in the U.S. midwest. The gene² crops _4_ to resist herbicides and that's _5_ farmers to wipe out milkweed, which is the main food source for Monarches. Scott Neuman, NPRNews, Washington.
每年春夏，在美国的许多地方都可以看到黑脉金斑蝶，它们在墨西哥中部度过冬季时遍布大片森林。但是最近几年，墨西哥的科学家发现了令人担心的趋势。每年迁徙时，过冬的黑脉金斑蝶会占据50平方英亩的森林，可是现在它们只占了不到3英亩。科学家认为这与墨西哥自然环境的砍伐现象有关。但是他们也提到了美国中西部地区大量种植的转基因玉米和大豆。基因作物可以抵抗除草剂，这样农民就可以用除草剂除掉马利筋，而马利筋是黑脉金斑蝶最主要的食物来源。NPR新闻，斯科特·纽曼华盛顿报道。
