　　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 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 to our expertise 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 that, we reserve the right to either accept or reject order requests at the discounted price.

　　Dear editor，

　　Dear_editor，

　　I'm_writing_to_tell_you_about_the_discussion_we_recently_had_about_whether_it_is_good_or_not_for_families_to_own_cars.

　　With the improvement of people's living conditions, more and more people have their own cars. Some of us think it's good to own a car. Firstly, it's a convenient, fast, and comfortable means of transportation. Secondly, it shows that people are becoming richer, and the country much more stronger. It also makes relative businesses and industries develop faster.

　　Others have different opinions. They think that cars give off waste gas and pollute the environment. Too many cars will have some bad effects, such as more accidents. Besides, overloaded parking cars is another big problem.

　　In my view, people should think carefully before they buy a car.

　　Yours_truly，

　　Li_Hua
