Perhaps the best way to think of our present situation is to imagine a train coming into a switchyard. All of the switches are set before the train arrives, so that its path is completely determined. Some switches we can see, others we can not. There is no ambiguity if we can see the setting of a switch: we can say with confidence that some possible futures will not materialize and others will. At the unseen switches, however, there is no such certainty. We know the train will take one of the tracks leading out, but we have no idea which one. The unseen switches are the true decision points in the future, and what happens when we arrive at them determines the entire subsequent course of events.
When we think about the future of the universe, we can see our "track" many billions of years into the future, but after that there are decision points to be dealt with and possible fates to consider. The goal of science is to reduce the ambiguity at the decision points and find the true road that will be followed.
According to the passage, it is difficult to be certain about the distant future of the universe because we ______.
A．have too many conflicting theories
B．do not have enough funding to continue our research
C．are not sure how the universe is put together
D．have focused on investigations of the moon and planets
听力原文：M: We seem to be having this conversation over and over again.
W: You're fight.
M: Look, I know how you feel about my smoking. You don't have to tell me every day.
W: I'm sorry. I worry about you.
M: Let's be honest. There's always going to be a reason. After you graduate, it's going to be hard to find a job, then there will be the stress from just starting a job.
M: OK, I get your point. It's just so hard. You don't really understand because you have never smoked.
W: You need some help. Why don't you go to a doctor？
M: You mean a psychiatrist？
W: No, I don't. I mean a general practitioner. Maybe you can get a patch, or some pills, well, I don't know, something to help you with the withdrawal.
M: Really, I believe I can quit on my own. But I'll think about it. I will.
W: All fight. I won't mention it for a week. Then I want to know your decision. Because if you don't get some help, I need to rethink our plans.
M: You mean you'd break our engagement over this？ I can't believe it!
W: I don't know.
What is the main topic of this conversation？
A．The man's graduation.
B．The couple's engagement.
C．The man's smoking.
D．The man's stress.
M: Well, everyone has been talking about having a barbecue down by the river, so why don't you pick up some ham burger and hot dogs？

M: Alright. What else？ Uh, we're gonna need some soft drinks, How about ten of those big 2-liter bottles？
W: Sounds fine, but be sure to buy a variety of drinks.
M: Okay. And what about dessert？
W: Well, maybe we could ask Kathy to make a few cherry pies like she did last time.
M: Well, I wouldn't mind that, but you know, she's been very busy working two jobs, so I'd hate to ask her, and uh... why don't you whip up some of your oatmeal cookies？ Hey, you could even ask, uh... ,what's her name... yeah that new girl, Susan, the one that moved in across the street! I bet she'd be willing to help you! She's a real knockout !
W: Nah, I don't think I could ask her... I don't know her phone number, plus...
[Door bell tings...]
M: Hey, you don't need to. She's at the door!

W: I can't. (22) In fact I need to finish early because I need go to the psychology department to talk to Professor Catherine about a job opening.
M: You mean a job on Campus？
W: Yeah. And it sounds pretty interesting. It involves helping with your study on learning style. You know, about how some people learn best by sight, while others learn best by hearing or touch.
M: Yeah. I know that's an area of special knowledge.
W: Right. In the study she's taking some high school students who aren't doing well in classes and testing them to find out their learning styles. (23) Then tutors, people like me, will work with them presenting material suitable for their particular learning style.
M: That is interesting. Now will you mostly do the testing or the tutoring？
W: Both I hope. I want to be involved from start to finish..
M: Are you getting paid for this？ W: Perhaps, but not much. (24) Anyway it doesn't matter. I just want to have some experience.
M: Yeah. And it'll be nice to help those students too.
W: That's what I thought when I saw the ad. You could do it too. You don't have to be in her classes to work on the study.
M: Really？ Do you have any idea of the schedule？
W: Late afternoon then evening for tutoring. After all the kids are in regular classes until three thirty.
M: Actually that's perfect for me.
W: Then come along. We will save the lab report for later. (25) But we'd better do a good job on our experiment first.
