I have watched a lot of your shows several times, and [must|should|can|would] be one of your biggest fans. The first time I saw you stick your hand in a nest of poisoning snakes, I [might not|should not|could not|would not] believe my eyes. In fact, some people have come to conclusion that you [ought to|must|need to|have to] be crazy to take risks like that. But they still [shouldn't| ought not to| would not to|are not able to] stop watching! Since your show started, you [can|have been able to|was able to|would have been] make a lot of people interested in nature. I'm one of those people. I am a high school senior, and because of your shows, I might major in zoology in college. I'm allowed to take general courses the first two years, so I [must not|can not|don't have to|am not able to] choose my major yet. One of my problems is that I'm afraid I [won't be able to|won't have to|won't need to|shouldn't] find a job when I graduate. What is your opinion? Will there be a lot of jobs in this field in the next few years? My other problem is that my parents don't want me to work with animals. They haven't actually said, "You [don't have to|are not able to|must not|might not] major in zoology," but they are really worried. What [should|must|have to|can] you tell them? I hope you will be able to find the time to answer this letter.
