Question

【題目】 Recently, China announced it had achieved success in drilling fire ice or methane hydrate(天然氣水合物,即可燃冰), from the seabed in the Shenhu area of the South China Sea. It produces high amount of energy when it is burned, leaving nothing but dioxide and water.

Many countries, including the United States and Japan, have long been doing research on methane hydrate, but taking it from bottom of the sea has been a common problem they are facing. According to reports, China succeeded in drilling methane hydrate for a number of days continuously and got an average of over 16,000 m daily. It is believed to be a big breakthrough.

Scientists say there is about 21,000 trillion (萬億 ) m of methane hydrate in the world. If we can use it, it can meet the world's energy need for 1,000 years. However, it is too early to say a new energy source (來源 ) has been found because we are still facing two main challenges ——environmental risk and economic (經(jīng)濟(jì)的) cost. When methane hydrate is taken from the seabed, it may go into the air easily. That's very bad for the environment because methane is one of the worst greenhouse gases. Besides, drilling methane hydrate is very expensive as well.

However, China's technology breakthrough is very important because it shows the way researchers across the world should take. It also raises hopes that one day we can drill methane hydrate as a source of energy.

【1】What is Paragraph 1 mainly about?

A.China is producing a large amount of energy from fire ice.

B.China is making good use of fire ice throughout the country.

C.China has already succeeded in drilling fire ice from the seabed.

D.China has turned fire ice from the South China Sea into daily energy.

【2】What's the common problem many countries are facing when doing research on fire ice?

A.How to take it out from the bottom of the sea.

B.How to turn it into useful energy at the lowest cost.

C.How to make it cheap on the future energy market.

D.How to change it into a traditional form of energy.

【3】Why is it too early to say a new energy source has been found?

A.Because it's too difficult to find the place where the fire ice lies and how to drill it.

B.Because it's not easy for fire ice to go into the air and be good for the environment.

C.Because it’s quite impossible for fire ice to take the place of other sources of energy.

D.Because it's expensive to drill fire ice and it may do great harm to the environment.

【4】Where can we probably read the article?

A.In a storybook.B.In a newspaper.

C.In a travel guide.D.In an advertisement.

Answer 1

【答案】

【1】C

【2】A

【3】D

【4】B

【解析】

本文講述了最近，中國宣布在中國南海深湖地區(qū)的海底成功開采了可燃冰。它燃燒時產(chǎn)生大量的能量，只留下二氧化碳和水。但是并不能大量開采，因為開采可燃冰費用高，還可能造成環(huán)境污染。

【1】段落大意題。根據(jù)“Recently, China announced it had achieved success in drilling fire ice or methane hydrate, from the seabed in the Shenhu area of the South China Sea.”可知第一段主要告訴我們，中國宣布在中國南海深湖地區(qū)的海底開采可燃冰成功，故選C。

【2】細(xì)節(jié)理解題。根據(jù)“Many countries, including the United States and Japan, have long been doing research on methane hydrate, but taking it from bottom of the sea has been a common problem they are facing. ”可知包括美國和日本在內(nèi)的許多國家長期以來一直在研究開采可燃冰，但從海底提取可燃冰一直是他們面臨的一個共同問題，故選A。

【3】推理判斷題。根據(jù)“However, it is too early to say a new energy source has been found because we are still facing two main challenges ——environmental risk and economic cost.”可知然而，現(xiàn)在說我們已經(jīng)找到了新能源還為時過早，因為我們?nèi)匀幻媾R兩大挑戰(zhàn)——環(huán)境風(fēng)險和經(jīng)濟(jì)成本，結(jié)合后面的展開論述可知，開采可燃冰費用高，還可能造成環(huán)境污染，故選D。

【4】推理判斷題。根據(jù)文章內(nèi)容可能是在報紙上看到的關(guān)于新能源的相關(guān)報道，故選B。
