Unit 4 Global warming Using language课时作业

　　Ⅰ.阅读理解

　　When I was a child growing up in Ohio, the butterflies would sometimes pass through on their way to Mexico. And it was awesome to see football fields full of them－and I wanted to revisit that on a larger scale. I knew I had to go to see the migration(迁徙) in Mexico.

　　But I was on a budget. I didn't want to rent a car in Mexico or take a bus to Valle de Bravo, the starting point for most butterfly adventures, so I called the guys at The Muddy Boot, travel experts in Mexico who can make almost anything happen at a reasonable rate.

　　And so, on January 2, I found myself in The Muddy Boot van (面包车) , being driven for two hours from Mexico City to Valle de Bravo, a lovely town on a volcanic lake which is a central point for the butterfly journeys. I booked a two­night stay at the Hotel Rodavento, an all eco­friendly hotel with individual wooden houses spreading throughout the forest and around a lake.

　　The first sanctuary (保护区) I visited was Piedra Herrada, a popular destination, as it is only 40 minutes away from Valle de Bravo. The climb up is tiring. It is advisable to hire a horse. But the horse cannot take you all the way, and there is some hiking in thin air, so you must be patient, drink a lot of water, and be in reasonably good shape.

　　The walk is more than worth it though. As I struggled to catch my breath, I looked up and lost my breath again. At first glance, the trees had turned into different shapes, but on closer inspection, every inch of them was covered with butterflies.

　　A few flew through the air (Most of them were not warm enough). As the sun rose, they began to come alive. Soon the air was filled with flying butterflies, transforming the forest into something magical and straight out of a fairy tale.
