Question

The number of buses, taxis and other vehicles on Kenya’s roads is growing every day. Now, the country’s first electric-powered motorbikes are coming onto the market. The bike is designed to cut down on pollution and aimed at low-income communities. Most motorbikes used in Kenya depend on gasoline, but not this new motorbike.

Three university students developed the new ecotran bike. It catches the sun’s energy, stores it in batteries and uses it to charge (充电) the electric motor. Robert Achoge is one of the student inventors. “Our hope is that by the fifth year, we will be able to cover the whole of Kenya with the electric motorcycle so as to protect the environment and provide affordable transport.”

The students have set up a charging station for the motorbikes in Nairobi. The small battery can run for 70 kilometers when fully charged. Once the power is used up, the motorbike has to return to the station while another charged battery is connected to the bike. The U.S. African Development Foundation (ADF) is helping set up two solar-powered charging stations in the port of Kisumu.

Each ecotran bike costs about $700. One taxi operator says the new motorbike costs less to operate than that running on traditional gasoline. “When it comes to buying gasoline, there’s no need. It’s basically good for various things. As long as you won’t take quite a heavy load (装载), you can go with it anywhere. Otherwise, it may break down halfway. But now people still have a preference to the gas-powered bikes.”

A Nairobi businessman Kennedy Kusimba is selling the ecotran bikes. He hopes they will become popular. “We also know they are more reliable compared to the gas-powered bikes. They are more efficient (效率高的) and they will last longer.”

【解析】

本文是一篇说明文，肯尼亚第一辆电动摩托车就要上市了，文章介绍了这种摩托车的优势及缺点，这种摩托车使用太阳能，非常环保。

1.细节理解题。根据第一段第二句Now, the country’s first electric-powered motorbikes are coming onto the market.可知肯尼亚第一辆电动摩托车就要上市了。故B项正确。

2.细节理解题。根据第二段第二句It catches the sun’s energy, stores it in batteries and uses it to charge (充电) the electric motor.可知这种新型的电动摩托车主要使用太阳能。故C项正确。

3.细节理解题。根据第四段第五句As long as you won’t take quite a heavy load (装载), you can go with it anywhere.可知这种电动摩托车不能装载太重。故A项正确。

4.推理判断题。肯尼亚第一辆电动摩托车就要上市了，本文主要介绍了这种摩托车的优势及缺点，这种摩托车使用太阳能，非常环保。本文不可能是广告、研究计划和商业报告，应该是与发明创造相关的科学杂志的内容。故D项正确。
