【正文】 ibrary here. They said their remaining positions were for workstudy students getting financial aid. I’ve never run into that before. Administrator： Well, I guess each school has its own policies. （ 5） Uh, we really don’t have much right now. You might be better waiting until next semester. If you really want something, how are your puter skills? Student： About average I’d say. I helped teach some of the basic puter classes. Northeastern offers for new users, if that helps any？ Administrator： OK, the technology support department needs people to work its helpdesk. It’s basically a customer service job, answering questions, helping people solve their puter problems, give you a chance to develop your people skills. Student： Something every diplomat needs. But is there some problem? I mean why is the job still open? Administrator： （ 4） Well, they have extended hours, from 6am to 2am every day. So they need a large staff. But right now they only need people early mornings, late nights, and weekends. You’d probably end up with a bit of everything rather than a regular spot. On the bright side you’ll probably be able to get some studying done between calls. At least it could be a start and then you can try for better hours next semester. Student： Um, I see why the hours might be a problem. But I guess I can’t afford to be too picky if I want a job. Still maybe we can work something out.. 詞匯： diplomat n. 外交家 helpdesk n. 幫助臺(tái) spot n. 地點(diǎn) picky adj. 挑剔的；吹毛求疵的 題目： 1.

Why does the professor imply about the discovery of a relationship between the sunspot cycle and Earth39。 答案： The copies had both artistic and political functions. 15. Why does the professor mention Roman coins? 解析：意圖推測(cè)題，文中說(shuō)硬幣在國(guó)家中散布，而帝王頭像印在硬幣上，說(shuō)明帝王頭像在國(guó)家散布。s possible participation in a research project 2.

The sale of spoiled food was prohibited. 9. Why does the professor mention the collapse of theRoman Empire? 解析：細(xì)節(jié)題，定位 the collapse of the Roman Empire. 文中說(shuō)羅馬瓦解后直接的貿(mào)易變 成了需要中介人的交易，這之后香料就帶上了一種神秘的色彩，所以它們的起源變得更加神秘。 Look for spices同義替換為 the demand for spices. 答案： They were responding to the demand for spices. 11.

What was the importance of Schwabe39。 答案： To imply that the student might not like the job that is available Lecture 1（學(xué)科分類(lèi) ——天文學(xué)） Narrow： Listen to part of a lecture in an astronomy class. Professor： We are going to start a study of sunspots today, and I think you’ll find it rather interesting. Now I’m going to assume that you know that sunspots, in the most basic terms, are dark spots on the Sun’s surface. That will do for now. The ancient Chinese were the first to record observations of sunspots as early as the year 165. （ 7） When later European astronomers wrote about sunspots, they didn’t believe that the spots were actually on the Sun. That’s because of their belief at the time that the heavenly bodies, the Sun, Moon, Stars, and Plas, were perfect, without any flaws or blemishes. So the opinion was the spots were actually something else, like shadows of plas crossing the Sun’s face. And this was the thinking of European astronomers until the introduction of the telescope, which brings us to our old friend, Galileo. In the early 1600s, based on his observations of sunspots. （ 8） Galileo proposed a new hypothesis. He pointed out that the shape of sunspots, well, the sunspots weren’t circular. If they were shadows of the plas, they would be circular, right? So that was a problem for the prevailing view. And he also noticed that the shape of the sunspots changed as they seemed to move across the Sun’s surface. Maybe a particular sunspot was sort of square, then later it would bee more lopsided, then later something else. So there is another problem with the shadow hypothesis, because the shape of a pla doesn’t change. What Galileo proposed was that sunspots were indeed a feature of the Sun, but he didn’t know what kind of feature. He proposed that they might be clouds in the atmosphere, the solar atmosphere, especially because they seemed to change shape and there was no predicting the changes, at least nothing Galileo could figure out. That random shape changing would be consistent with the spots being clouds. Over the next couple hundred years, a lot of hypotheses were tossed around. The spots were mountains or holes in the solar atmosphere through which the dark surface of the Sun could be seen. Then in 1843, an astronomer named Heinrich Schwabe, made an interesting claim. Schwabe had been watching the Sun every day that it was visible for 17 years, looking for evidence of a new pla. And he started keeping tracks of sunspots, mapping them, so he wouldn’t confuse them with any potential new pla. （ 9） In the end, there was no pla, but there was evidence that the number of sunspots increased and decreased in a pattern, a pattern that began repeating after 10 years, and that was a huge breakthrough. Another astronomer named Wolf kept track of the Sun for an even longer period, 40 years actually. （ 10） So Wolf did 40 years of research, and Schwab
