15．I have been homeschooled my entire life．I do know that I would not be who I am today if I had not been homeschooled．
One of the things I think is so great about homeschooling is that every family is different．Some homeschool parents assign a week's worth of schoolwork on Monday and tell the kids to complete it when they get to it during the week； others sit down with their kids and do school for a certain amount of time each day．It's entirely up to the family．
Another thing that's great is that if I don't understand something，my mom can sit down with me and help me one-on-one until it clicks．Because she only has three students to teach，she has more time to make sure we all understand our work．
Being homeschooled，I don't think that my life lacks anything．I know that I'm getting a good education and，contrary to what many people think，homeschoolers are not necessarily socially deprived （剥夺）．My family belongs to homeschool group，and if we ever want to hang out with other homeschoolers we can．I'm a fourteen-year-old girl with many friends，both boys and girls．
Yes，I'm somewhat different from everyone else---but everyone is unique．If everyone was the same，where would the variety be？I'm different in many ways，but I'm also similar to other teens in many ways，too．I love Katy Perry and the Black Eyed Peas．I like chatting and hanging out with friends，and I like talking on the phone．
I take pride in the fact that I'm homeschooled．I love to be different，and I love to be who I am．Homeschooling is the right thing for me，and if my mom offered me the chance to go to public school I would turn it down immediately．
I am homeschooled，and that is something I am and will continue to be proud of．

19．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（白鼻综合征）"had killed 93percent of New York State's bats （and about 6million 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 stop？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 crop-damaging 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 5-year-olds 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'11be happy．
