A
In many parts of Africa, communities have electricity service that sometimes does not operate.And many rural (农村的) settlements are cut off from electricity producing centers.Therefore, offgrid (离网) solar power is becoming available to many communities.Offgrid solar energy is energy that is captured from the sun without being connected to a main electricity center.The International Energy Agency says more than 600 million people in Africa have no way to get electricity.New technology, however, could help solve this problem.
Lumos Global is among the companies offering solar energy services in Nigeria.The company's Chief Operating Officer, Nir Marom, says, “You need to put the system on the roof, and put the indoor unit in the home.There is a cable (电缆) to connect them.You don't need to be an electrician or anything like this.The sun charges the electricity, but you need to provide the credit to power the system up, and you do this using your mobile phone.” The price of offgrid solar energy systems has decreased sharply.Today, people can rent solar equipment for less than 50 cents a day.And they can pay for the electricity as they need it.
Senegal opened one of Africa's largest solar factories last year.The company paid for the construction of the solar factory in Senegal.A manager says a solar farm in Senegal can produce twice the amount of electricity that a farm of the same size in Britain or in northern France could produce.The International Energy Agency predicts that almost a billion people in subSaharan Africa will have ongrid electricity by 2040.But the agency says 50 million people will still be offgrid.Investors believe solar power could serve those people while also helping to reduce gases linked to climate change.
语篇解读：本文是一篇说明文。在非洲的许多地方，社区配有电力服务，不过有时候无法运行。并且，发电中心切断了许多村落的电力。幸运的是，新技术——离网太阳能可以解决这一问题。
1．Why is the offgrid solar power popular in Africa?
A．Many people have difficulty in getting electricity.
B．There is no electricity producing centers.
C．It's a fashion among the communities.
D．It's convenient to put the energy into use.
解析：选A 推理判断题。根据第一段可知，在非洲很多地方人们都无法用上电，这使得offgrid solar power在非洲得以流行起来。
2．What does Nir Marom say about the offgrid solar energy system?
A．It's complex to change sunlight into energy.
B．It's simple to put the equipment in place.
C．It's beyond the reach of ordinary people.
D．It's free for people to use the system.
解析：选B 细节理解题。根据文中第二段Nir Marom所说“You don't need to be an electrician or anything like this.”可知，安装太阳能设备非常简单。
3．What can we learn from the last paragraph?
A．The solar energy system in Africa develops faster than that in Europe.
B．Half of the people in Africa have no access to electricity.
C．The usage of solar power is good for the environment.
D．All the people in Africa can use electricity by 2040.
解析：选C 细节理解题。根据最后一段最后一句可知，太阳能的使用不仅可以满足人们需要，还可以减少与气候变化有关的温室气体的排放。即太阳能的使用对环境有益。
4．What may be the best title for the text?
A．This is the best way to get electricity
B．Africa is facing severe energy shortages
C．Solar electricity production grows in Africa
D．Offgrid solar energy is better than ongrid solar energy
解析：选C 标题归纳题。纵观全文，文章主要介绍了太阳能发电在非洲非常流行。
