Question

【題目】 Researchers in Australia have discovered an effective new method to capture the atmospheric carbon dioxide that is damaging our planet and transform it into something solid, making it much easier to store.

Carbon capture isn’t new, but previous methods call for the gas to be compressed into liquid and then injected underground. Widespread usage of that technology has been locked by economic and environmental concerns due to possible leaks. Instead, in a study published in Nature Communications, the group details their sustainable and cost-effective plan for transforming CO2 into coal.

This new process involves a liquid metal catalyst( 催化劑 )that is efficient in conducting electricity. CO2 gas is dissolved in a container with some liquid. Once electricity charge is introduced, the CO2 begins to turn into solid pieces of carbon, which can be collected and stored.

What makes this particularly unique is that the entire process can occur at room temperature. Previous experiments have only shown a gas to solid conversion at extremely high temperature, which made it impossible on a large scale. Now, the researchers are hoping that their work will be used to create even further when it comes to carbon storage.

In an interesting side benefit, the solid carbon also works as an electrode( 焊 條 ), which opens up a world of possibilities. “A side benefit of the process is that the carbon can hold electrical charge, becoming a super battery, so it could potentially be used as a part in future vehicles,” explains Dr. Dorna Estrafilzadeh, a researcher. “The process also produces fuel as a by-product, which could also have industrial applications.”

【1】What can we know about the previous carbon capture methods?

A.People have to inject liquid to the gas.

B.The previous methods can be done easily.

C.The previous methods are not very popular.

D.People have widely accepted previous methods.

【2】What is the special part of the new method?

A.It needs electricity to make the process efficient.

B.It can be done in any kind of container.

C.It doesn’t need extreme temperature.

D.It can produce much solid carbon.

【3】What can we infer from the last paragraph?

A.The method will make fossil oil disappear.

B.The method will influence the future industry.

C.The method will make developed countries more powerful.

D.The method will be used to make new vehicles.

【4】What is the best title for the passage?

A.How to change carbon into CO2.

B.A new carbon capture technology.

C.A new technology to get useful carbon.

D.Australia makes the world cleaner than before.

【3】B

【4】B

【解析】

這是一篇說明文。文章主要介紹了一種新的碳捕獲技術(shù)的原理，優(yōu)點(diǎn)和對未來工業(yè)的影響。

【1】細(xì)節(jié)理解題。根據(jù)文章第二段的Widespread usage of that technology has been locked by economic and environmental concerns due to possible leaks.可知之前技術(shù)的廣泛應(yīng)用受到了經(jīng)濟(jì)和環(huán)境方面的限制。C. The previous methods are not very popular.（以前的技術(shù)沒有廣泛普及）符合以上說法，故選C項(xiàng)。

【2】細(xì)節(jié)理解題。根據(jù)文章第四段的What makes this particularly unique is that the entire process can occur at room temperature.可知新技術(shù)獨(dú)特的地方是整個過程可以在室溫條件下進(jìn)行。C. It doesn’t need extreme temperature.（它不需要極高的溫度）符合以上說法，故選C現(xiàn)。

【3】推理判斷題。根據(jù)文章最后一段的內(nèi)容，尤其是which opens up a world of possibilities； it could potentially be used as a part in future vehicles和 which could also have industrial applications可知這種技術(shù)的產(chǎn)物開辟了很多新的可能，可以被變成超級電池為未來車輛供能，過程中的副產(chǎn)品可以作為燃料應(yīng)用到工業(yè)中，由此推測該技術(shù)會對未來的工業(yè)產(chǎn)生巨大影響。B. The method will influence the future industry.（這種方法將會影響未來的工業(yè)）符合以上說法，故選B項(xiàng)。

【4】主旨大意題。本文是說明文，其主旨一般在首段或者尾段。根據(jù)文章第一段Researchers in Australia have discovered an effective new method to capture the atmospheric carbon dioxide 和下文講述的內(nèi)容可知，本文主要介紹了一種新的碳捕獲方法的原理和優(yōu)點(diǎn)及其影響。B. A new carbon capture technology. （一種新的碳捕獲技術(shù)）可以作為本文標(biāo)題，故選B項(xiàng)。
