疑难解析
1. Should I assume the other students don't know much, and give them a kind of general introduction, or should I try and make them share my fascination with a particular aspect？我应该假设其他人不怎么了解（纳米技术领域）而大致介绍一下，还是应该和大家分享一下我对某一个领域的迷恋呢？本句中fascination一词字面含义为“迷恋”，考生可理解为Russ对某一领域的喜爱。
2. While it can be good to include slides, you could end up spending too long looking for suitable ones. You might find it better to leave them out.尽管有幻灯片挺好的，但你有可能花太多时间在寻找合适的内容上。你可能会发现还是不要的好。leave...out指“排除”。
3.That would be fine if you had an hour or two for the presentation, but you might find that you can't do anything with the answers you get， and it simply eats into the short time that＇s available.如果你的演讲有一两个小时还可以，但你可能会发现听众的回答没什么意义，而且会消耗本来就不多的时间。eat into表示“消耗”，等同于use up.
4.Let's say it was better in some respects than in others. With regard to the structure, I felt that you ended rather abruptly， without rounding it off.一些方面肯定比另一些方面好。关于结构，我觉得结尾有点仓促，没有圃满结束。考生需掌握短语round off。
5. And you kept scratching your head, so I found myself wondering when you were next going to do that,instead of listening to what you were saying！你总是挠头，所以我发现我一直在关注你什么时候会再挠，而不是去听你的内容！本句中 when you were next going to do that 也可以表达为when you were going to do that next，语义相同。
