Ex Input:
M: What do you want to do after graduation, Mary? ,F: I like to go into the management. I've applied for several jobs, and already got some offers. ,M: Good for you, Mary. You are always about the most hard-working student in our class and your efforts finally paid off. ,F: It's so nice of you to say so, Lucas. And how about you? ,M: I have to do some more studies to become a lawyer. ,F: Oh, being a lawyer is not easy nowadays. And you have to overcome a lot of difficulties to achieve your ambition. ,M: Definitely. But if our ambitions were so easy to achieve, we would soon get bored. ,F: That's sure. But there's another story. Some people were working really hard yet not succeed. ,M: That is why ambition needs to be realistic. You can't (?) too high. ,F: Sounds reasonable. But according to my understanding, a careful plan in advance places the most important role in achieving success. ,M: You're right. In addition, interest is the best teacher. Like a saying goes, "You can lead a horse to river, but you can't force it to drink." ,F: I can't agree more. My father wanted me to be a surgeon when I choose my major in college. But I'm not interested in any hospital jobs. ,M: A good doctor should be mentally physically strong. ,F: Definitely. I don't think it's possible for me to do the surgeons' work under great pressure, so I will stick to what I'm good at. ,M: How I wish our parents won't push us too much.
(A) F: Yes. But I just chose to follow my heart and go into management. (B) F: Yes. I listened to my father and chose doctor as my major. (C) F: I am really sorry, I did not catch that. Would you slow down, please? (D) F: Yes. I argued so many times with my father about the major and finally chose doctor.
