Question

【題目】 The world's first hydrogen-powered(氫動力) trains have begun running in Germany last month. The new trains will run 100-kilometer trips and can travel up to 140 kilometers an hour.

A French railroad company called Alstom built two hydrogen-powered trains. Teams in Germany and France cooperated on the project, which was supported by the German government. The new train model, called the Coradia iLint, signals the beginning of efforts in Germany and other nations to move away from pollution-producing diesel(柴油) trains.

Compared(與…相比較) with diesel trains, the Coradia iLint is designed to run on non-electrified train lines with low levels of noise. It uses a process that combines hydrogen and oxygen to produce electrical power. If the system produces more energy than the train needs at that time, it can store the extra energy in batteries. The only emissions(排放物)are water and steam.

A single tank of hydrogen can run a Coradia iLint train for about 1,000 kilometers. This is very similar to the distance a diesel-powered train can run on with a single tank.

Hydrogen-powered trains cost more than diesel trains to build. But Alstom officials say the operating costs are much lower. The company plans to provide another 14 Coradia iLint trains by the year 2021. Several other European countries have also expressed interest in developing hydrogen train systems. France has already said it wants its first hydrogen train to be operated by 2022.

【1】What's the topic of the passage?

A. A new kind of train

B. Diesel(柴油) trains

C. Water and steam

D. A French railroad company

【2】Compared with diesel trains, what's the advantage of the Coradia iLint?

A. The Coradia iLint uses electrical power.

B. The Coradia iLint can store the extra energy in batteries.

C. The Coradia iLint is designed to run with low levels of noise.

D. All of the above.

【3】How many Coradia iLint trains in total will the Alstom have by the year 2021?

A. Two B. Fourteen C. Twelve D. Sixteen

【4】According to the passage, we can infer that __________.

A. Alstom is the name of hydrogen-powered(氫動力) train.

B. The project was supported by the French government.

C. A diesel-powered train can run about 1,000 kilometers with a single tank.

D. Only one European country has interest in developing hydrogen train systems.

Answer 1

【答案】

【1】A

【2】D

【3】D

【4】C

【解析】

本文是說明文。短文介紹了上個月研發(fā)的開發(fā)氫動力列車系統(tǒng)的情況。該火車和內(nèi)燃機(jī)車相比具有噪音低，運行高效，污染小的優(yōu)點。同時具有建造費用高的不足。

【1】主旨大意題。根據(jù)本文介紹了開發(fā)氫動力列車系統(tǒng)的情況，可知A new kind of train 一種新型火車是最恰當(dāng)?shù)臉?biāo)題 ，故選A。

【2】細(xì)節(jié)理解題。根據(jù) The Coradia iLint is designed to run on non-electrified train lines with low levels of noise. It uses a process that combines hydrogen and oxygen to produce electrical power. If the system produces more energy than the train needs at that time, it can store the extra energy in batteries. The only emissions are water and steam. Coradia iLint被設(shè)計用于非電氣化列車線路，噪音低。它采用了氫氧結(jié)合產(chǎn)生電能的生產(chǎn)流程。如果系統(tǒng)產(chǎn)生的能量超過了當(dāng)時列車所需的能量，它可以將額外的電能儲存在電池中。這種列車唯一的排放物是水和蒸汽，可知，與柴油火車相比Coradia iLint的優(yōu)點是使用電力，可以將多余的能量儲存在電池中，在低水平噪音運行 ，故選D。

【3】細(xì)節(jié)理解題。根據(jù) A French railroad company called Alstom built the two trains 法國阿爾斯通鐵路公司建造了這兩輛列車和 The company plans to provide another 14 Coradia iLint trains to Lower Saxony by 2021 該公司計劃在2021年前向下薩克森州提供另外14輛Coradia iLint列車，可知， 到2021年阿爾斯通總共將擁有16輛Coradia ilint列車，故選D。

【4】推理判斷題。根據(jù)A single tank of hydrogen can run a Coradia iLint train for about 1,000 kilometers. This is very similar to the distance a diesel-powered train can run on with a single tank.可知，一罐氫可以讓氫動力列車跑差不多一千公里。這和一罐柴油讓一輛柴油驅(qū)動的火車跑1000公里差不多，故選C。
