Question

What if we could replace oil with a fuel which produced no pollution and which everybody had equal access to?The good news is that we can, In fact, we are swimming in it—literally.

Hydrogen is one of the building blocks of the universe ,Our own sun is basically ,a big ,dense cloud of the stuff ,And hydrogen can be used to create electricity for power ,heat and light.

The problem is that hydrogen is everywhere and nowhere at the same time , It does not exist as a material on its own ,but is always part of something else, So it has to be separated before it can be used.

Most commercial hydrogen in use now is created from natural gas , As oil will start to run out in around the year 2030.,it makes sense to produce as much hydrogen as possible as soon as we can ,But natural gas supplies will also begin to run out soon after, Another source is needed.

Researchers are now using electricity to make water into hydrogen ,Companies are working on the problem in their own areas ,The first commercial hydrogen ,”fuel cells”for computers and mobile phones have already come on to the market ,Auto companies have also invested over US ＄2billion in the production of hydrogen fuelled cars

Thd nations of a hydrogen fuelled planet would not fight over evergy recourses, There would be a great reduction in pollution ,The only by-product of creating hydrogen is pure drinking water—something that is very scarce in many parts of the world ,But that is not where the good news ends, Once the costs of producing hydrogen have been brought down ,it will possibly provide power for a third of the Earth ‘s population that has no electricity.

And electricity creates wealth, In South A frica over the last decade there has been a large programme of electrification, Thanks to the programme, people do not have to spend their days looking firewood to burn for heat, And with electric light , they can work long into the night.

Some scientists see radical changes in the way the human race co-operates, Hydrogen creates clectricity, and is also created by it. With dual use fuel cells, everyone who consumes energy could also produce it ,Late at night, a man drives home in London and connects his car into the “world-wide hydrogen web”, which it supplies with electricity ,A few hours later, a man in Beijing uses that electricity to power the hydrogen cell in his car, Hydrogen could be the first democratic energy source.

Like all dreams of the future, it seems very far away, But the threat of war and terrorism in the Middle East has made governments and businesses more aware of the need to edn oil dependency and spend more time and money on hydrogen resource, So maybe the threat of war is not a completely bad thing for the future of the human race.

A、To tell us that we produce energy while using hydrogen power

B、To tell us that hydrogen power does not produce pollution

試題分析：本文主要講述的是為了我們的資源可能會枯竭，但是我們可以使用新型的hydrogen能源作為我們的主要資源。文章具體描述了分類hydrogen的困難等

1.C 推理題。根據(jù)本句Some scientists see radical changes in the way the human race co-operates, Hydrogen creates electricity, and is also created by it.可知這里的it就是指前一句里的clectricity指這兩種物質(zhì)Hydrogen和electricity是相互依存的。故C正確。

2.B 推理題。根據(jù)文章第三段The problem is that hydrogen is everywhere and nowhere at the same time , It does not exist as a material on its own ,but is always part of something else, So it has to be separated before it can be used.可知最大的問題是hydrogen并不是單獨存在的，而是和其他的物質(zhì)在一起的。所以要使用hydrogen，首先就是要把hydrogen分離出來。故B正確。

3.A 推理題。根據(jù)文章倒數(shù)第二段1,2行Some scientists see radical changes in the way the human race co-operates, Hydrogen creates clectricity, and is also created by it. With dual use fuel cells, everyone who consumes energy could also produce it可知舉這個例子就是為了告訴我們在分離出hydrogen的時候，我們也需要消耗電能等其他能源。故A正確。

4.D 推理題。根據(jù)文章最后一段Like all dreams of the future, it seems very far away, But the threat of war and terrorism in the Middle East has made governments and businesses more aware of the need to edn oil dependency and spend more time and money on hydrogen resource可知作者對于未來并不是很擔(dān)憂 ，而是有樂觀的觀點。故D正確。

5..B 主旨大意題。本文主要講述的是為了我們的資源可能會枯竭，但是我們可以使用新型的hydrogen能源作為我們的主要資源。文章具體描述了分類hydrogen的困難等。故B正確。
