M: Good evening and welcome to Physics Today. [5] Here we interview some of the greatest minds in physics as they help us to understand some of the most complicated theories. Today, I’ m very pleased to welcome Dr. Melissa Phillips, professor of theoretical physics. She’ s here to tell us a little about what it is she studies. Dr. Phillips, you seem to study everything.
W: [6] I guess that would be fair to say I spend most of my time studying the Big Bang Theory and where our universe came from.
M: Can you tell us a little about that?
W: [7] Well, I’ m very interested in why the universe exists at all. That may sound odd, but the fact is at the moment of the Big Bang, both matter and anti-matter were created for a short time, and I mean just a fraction of a second. The whole universe was a super hot soup of radiation filled with these particles. So what baffled scientists for so long is why is there a universe at all?
M: That’ s because matter and anti-matter are basically opposites of each other. They are exactly alike, except that they have opposite electrical charges. So when they collide, they destroy each other?
W: Exactly. So during the first few moments of the Big Bang, the universe was extremely hot and very small. Matter, and the now more exotic anti-matter, would have little space to avoid each other. This means that they should have totally wiped each other out, leaving the universe completely barren.
M: [8] But a recent study seems to point to the fact that when matter and anti-matter were first created, there were slightly more particles of matter, which allowed the universe we all live in to form?
W: Exactly. Because there was slightly more matter, the collisions quickly depleted all the anti-matter and left just enough matter to create stars, planets, and eventually us.
Questions 5 to 8 are based on the conversation you have just heard.
5. What does the man say is Physics Today?
6. What is the woman physicist’s main research area?
7. What is the woman interested in?
8. What seems to be the finding of the recent study?
选项
A、Matter and anti-matter are opposites of each other.
B、Anti-matter allowed humans to come into existence.
C、The universe formed due to a sufficient amount of matter.
D、Anti-matter exists in very high-temperature environments.
答案
C
解析
题干问的是最新研究的发现是什么。对话的后半部分男士说最近的一项研究似乎指出,当物质和反物质第一次被创造出来时,物质更多,因此我们所生活的宇宙才得以形成,故答案为C(宇宙是由足够数量的物质形成的)。A项(物质和反物质是相互对立的)和D项(反物质存在于高温环境)并不是最新研究发现的,故排除。B项(反物质使人类得以生存)与对话内容相悖,故排除。
