(·高考北京卷，A)We all know that the cost of heating our homes will continue to be a significant burden on the family budget.Now millions of people are saving on their heating bills with the EP portable heater.With over one million satisfied customers around the world，the new EP heats better and faster，saves more on heating bills，and runs almost silent.
The EP has no exposed heating parts that can cause a fire.The outside of the EP only gets warm to the touch so that it will not burn children or pets.
The EP will not reduce oxygen in the room.With other heaters，you’ll notice that you get sleepy when the heat comes on because they are burning up oxygen.
The advanced EP also heats the room evenly，wall to wall and floor to ceiling.It comfortably covers an area up to 350 square feet.Other heaters heat rooms unevenly with most of the heat concentrated to the center of the room.And they only heat an area a few feet around the heater.With the EP，the temperature will not vary in any part of the room.
The EP comes with a 3year warranty (保修) and a 60day，no questions asked，satisfaction guarantee.If you are not totally satisfied，return it at our expense and your money will be given back to you.
Now we have a special offer for 10 days，during which you can enjoy a half price discount and a free delivery.If you order after that，we reserve the right to either accept or reject order requests at the discounted price.

解析：本文是一篇说明文，属于广告文体，介绍了一种新型的便携式暖风机。与其他的暖风机相比较，它有很多优点，写这篇文章的目的是让读者买他们的产品。
【小题1】解析：选B。主旨大意题。本题考查考生整体把握、提炼信息、概括部总结段落大意的能力。A项“EP暖风机的热量”；B项“EP暖风机的安全”；C项“EP暖风机的外表”；D项“EP暖风机的材料”。由第二段的内容可知，这种暖风机不会引起火灾，不会烫伤孩子和宠物，显然是在讲它的安全性，故正确答案为B项。
【小题2】解析：选A。细节理解题。根据文章第三段第一句话The EP will not reduce oxygen in the room.可知，这种EP暖风机是不会降低室内的氧气含量的，就是说该暖风机不消耗氧气，故正确答案为A项。
【小题3】解析：选D。词义猜测题。由文章第四段可知，此处把EP暖风机与其他的类似产品相比较，这种暖风机能够把墙、门、天花板都加热，不像以前的产品，只加热附近小片区域，因此该词义为“均匀地，平等地”，故D项正确。
【小题4】解析：选A。推理判断题。A项“说服人们买该产品”；B项“建议人们节省加热的钱”；C项“报道便携式暖风机的最新发展”；D项“比较不同品牌暖风机的性能”。根据文章内容可知，本文为广告文体，向大家介绍了一种新型的暖风机，与其他的暖风机相比，它有自己的优点，其目的是让读者买他们的产品，因此A项正确。
