阅读理解     Mosquitos (蚊子)can cause us serious diseases. Until now. we've used different things to keep them away. But none of these ways actually protect us for more than 20 minutes! Now there is a new way to keep mosquitos away from you ever again without using any chemicals at all.     What is it all about?     It's called the Mosquitron—a new mosquito catcher or killer. It's very easy to control and it can protect your home from all the mosquitos!     How does it work?     Instead of trying to keep the mosquitos away, it attracts them, then catches them and finally kills them! Basically, it will attract the mosquitos into the Mosquitron, with a completely harmless UV-PT producing light. Next to the UV-PT light is a powerful reverse (反向的)fan that sucks (吸)the mosquitos through a one-way trapdoor. Once they are trapped in the drying basket« they are dried to death by the fan in 2 minutes.     How much does it cost?     You'd be surprised to find that you can get it right now for just $89. It might seem expensive at first. However, when you compare it with other products which need regular, expensive repair and don't work for more than 10 minutes, it is pretty cheap. In fact, some products using the same UV technology are priced over $250! to buy a mosquitron?     That's very easy.
