3、r imaginations. Instead， they are produced by a machine. These new floating advertisements are called Flogos； the name stands for “floating logos.” Theyre made from a mixture of soapy foam (泡沫) and a lighterthanair gas such as helium，and they can be made into different sizes and shapes depending on
4、the advertisement.,Flogos can last up to an hour if weather conditions are good， and they can fly several kilometers high. Advertisers can rent a Flogo machine for $2，500 a day. The setup is normally performed within 1 to 2 hours， and it will release four Flogos per minute. Advertisers can fill the
5、air with any shape or message they want.,Some people are worried that the Flogos might not be pollutionfree (无污染的). However， the Flogos inventor insists that the soap he uses is natural， and that a Flogo just dissipates (消失) in the air， leaving nothing behind. Though it may be true that Flogos are e
6、nvironmentally friendly， some people believe that the natural clouds in our memory may be replaced by manmade ones. They are afraid that soon there will be nowhere left where their imaginations can float freely.Section_Warming Up & Reading Prereading原文呈现读文清障THE PROBLEM OF THE SNAKESWhen I called up

Can you get rid of them please？” I felt very proud. Here was a c

At the same time I prepared some icecubes.The next morning I got up early before the sun was hot. I placed the frozen
