Unit 22 课时跟踪练(三) Lesson 2 & Lesson 3 - Prereading

　　Ⅰ.阅读理解

　　A

　　When I was little, I'd see tons of bats flying around streetlights at night in my neighborhood in upstate New York.

　　By the time I turned 7, I noticed something strange: All the bats in my neighborhood had vanished,_and I wondered why. Later I learned what had happened to my town's bats. A disease called "white nose syndrome (白鼻综合症)" had killed 93 percent of New York State's bats (and about 6 million bats across the country)! I was shocked. I asked the bat biologist what I could do to help, and she said, "Tell others what's been happening. Help people understand that bats are important to our environment and need to be protected."

　　I thought I must teach people about bats. My first step? The library, where I eventually checked out every book on bats they had. Next, I started a Facebook page called Buddies for Bats and posted any photos, facts, and videos that I could find. Then I wrote a letter to the host of an environmental program on my local radio station, asking if they'd do a show on bats. (They did！)

　　But I still wanted to find a way to educate people face to face. I managed to make a presentation to a school. I also used tools to describe how bats help farmers (and protect our food supply) by eating crop­damaging insects.

　　I practiced my presentation until it shone like a polished stone. It went over so well that other teachers started requesting me. Over the past three years, I've talked in front of everyone from 5­year­olds to senior citizens! The more I present, the more I notice that I am changing minds. I have watched people go from dismissing bats as "disgusting (令人厌恶的)" to truly understanding them and advocating their protection.

　　Right now, I'm thinking of becoming a marine biologist (海洋生物学家) someday. As long as I'm helping animals, I'll be happy.
