Section 4. You will hear a woman talking to a group of first year science graduate students about the developing of science nanotechnology.
第四部分。你將會聽到一位女士對一群科學(xué)系一年級的研究生談?wù)撘豁棸l(fā)展中的科學(xué)——納米技術(shù)。
First, you'll have some time to look at the questions 31 to 40.
在播放錄音之前，你有一些時間閱讀問題31-40。
Now, listen carefully and answer questions 31 to 40.
現(xiàn)在請仔細(xì)聽錄音并回答問題31-40。
Today we're going to look at an important area of science, namely nanotechnology. So what is it?
今天我們要來看看一個重要的科學(xué)領(lǐng)域，也就是納米技術(shù)。納米技術(shù)是什么呢？
Nano means tiny, so it's science and engineering on the scale of atoms and molecules.
納米指的是很小的東西，所以納米技術(shù)是在原子和分子范圍內(nèi)的科學(xué)工程。
The idea is that by controlling and rearranging atoms, you can literally create anything.
想法是這樣的：通過控制和重新排列原子，我們能創(chuàng)造出任何事物。
However, as we'll see, the science of the small has some big implications affecting us in many ways.
可是，如我們將看到的，這項關(guān)于小東西的科學(xué)在很多方面對我們產(chǎn)生了巨大的影響。
There's no doubt that nanotechnology promises so much for civilisation.
毫無疑問納米技術(shù)在文明發(fā)展方面充滿前景。
However, all new technologies have their teething problems.
但是所有的新科技在發(fā)展初期都會出現(xiàn)問題
And with nanotechnology society often gets the wrong idea about its capabilities.
而對于納米技術(shù)，人們經(jīng)常對它的能力產(chǎn)生錯誤的想法。
