单选题Read the following text. Choose the best word(s) for each numbered blank and
mark A, B, C or D. Besides climate change,
developing countries like China need to deal with energy {{U}} {{U}}
1 {{/U}} {{/U}}and environmental issues: the development of sources of
clean energy needs to be {{U}} {{U}} 2 {{/U}} {{/U}}line with
their interests. Clean energy has been given greater prominence than ever
before; it is seen as a new industrial {{U}} {{U}} 3 {{/U}}
{{/U}}and {{U}} {{U}} 4 {{/U}} {{/U}}of economic growth for the
new century. The time for clean energy has come. In China,
clean energy is moving ahead at full speed. Take wind power as an example: by
the end of last year, China had {{U}} {{U}} 5 {{/U}} {{/U}}wind
power generating capacity of 12.21 GW, making China the largest wind power
generator in Asia and fourth in the world. But according to the research,
one-third of wind power capacity is running {{U}} {{U}} 6
{{/U}} {{/U}}due to an inability to get the power to the national {{U}}
{{U}} 7 {{/U}} {{/U}}. India-like China—relies
{{U}} {{U}} 8 {{/U}} {{/U}}on coal for its energy needs. This
will only change if the funds and technology to develop clean energy, such as
wind and nuclear power, are {{U}} {{U}} 9 {{/U}} {{/U}}. India
will not choose clean energy {{U}} {{U}} 10 {{/U}} {{/U}}.
Nuclear power is currently the most {{U}} {{U}} 11 {{/U}}
{{/U}}of clean energy sources. {{U}} {{U}} 12 {{/U}} {{/U}}, if it
is to be {{U}} {{U}} 13 {{/U}} {{/U}}on a large scale by
developing nations, technological advances will be needed to make it competitive

{{/U}}developed countries, developing countries have more {{U}} {{U}}
15 {{/U}} {{/U}}choices when it comes to energy structure. Promoting
economic growth requires {{U}} {{U}} 16 {{/U}} {{/U}}energy—and
coal, the cheapest and most {{U}} {{U}} 17 {{/U}} {{/U}}source
of energy for many countries—is the {{U}} {{U}} 18 {{/U}}
{{/U}}choice. Cheap coal means cheap electricity and a competitive economy. Rising
electricity prices would cause public {{U}} {{U}} 19 {{/U}}

【答案解析】[解析] be on line“在运转”、“在线的，上网的”；be in line with“与…保持一致”；be with line with没有这种用法；along the line“在某一环节”。本句中“be in line with their interests”的意思是“和他们自身的利益相符合”。所以，本题选择B。
单选题
A.revolution
B.evolution
C.advance
D.development
【正确答案】
A
【答案解析】[解析] revolution“革命”、“大变革”；evolution“进化、演变”；advance“进步、进展”；development“发展”。由上一句“Clean energy has been given greater prominence than ever before (各国将清洁能源发展提上了前所未有的高度)”以及下半句“...of economic growth for the new century(新世纪的经济增长)”可推知，清洁能源不仅仅是新的产业发展，而是一轮产业革命，它将推动经济增长。所以，本题选择A。
单选题
A.resource
B.reason
C.root
D.source
【正确答案】
D
【答案解析】[解析] resource“资源、资料”；reason“原因”，表示“…的原因”时，用介词for，比如，She gave no reasons for her decision.她没有对她的决定做出任何解释。root主要指一个问题的根源、起因，比如。What lies at the root of his troubles is a sense of insecurity.他的一切忧虑源于一种不安全感。source“起源、源头、根源、原因”。本句的意思是清洁能源成为新世界经济增长的源头，选项A，B和C均不适合。所以，本题选择D。
【答案解析】[解析] provident“精打细算的、未雨绸缪的”；providential“及时的、适时的”；providing“如果、假如”；provide“提供、供应”。本句“This will only change if the funds and technology to develop clean energy, such as wind taxi nuclear power, are provided.”的意思是“只有为印度提供资金和技术，发展风能、核能等新能源，这种情况才能有所改变。”选项A，B和C均不适合。所以，本题选择D。
单选题
A.by itself
B.on its own
C.voluntarily
D.automatically
【正确答案】
B
【答案解析】[解析] by itself“自动、单独”；on its own“独立地”；voluntarily“自愿地”；automatically“自动地”。由上文“This will only change if the funds and technology to develop clean energy, such as wind and nuclear power, are provided.(让印度改变以煤为主的能源结构，唯一途径是为印度提供资金和技术，发展风能、核能等新能源。)”可推断出下文的意思是“印度不会独立地走上清洁能源之路。”所以，本题选择B。
单选题
A.cheapest
B.expensive
C.competitive
D.advanced
【正确答案】
C
【答案解析】[解析] cheapest“最便宜的”；expensive“最贵的”；competitive“最具有竞争力的”；advanced“先进的”。选项A，B和D在文章中均没有体现。由下句的“technological advances will be needed to make it competitive with coal.(通过进步技术使利用核能可以与煤炭竞争。)”可推知，在清洁能源中，核电是最有竞争力的，只是在与煤炭竞争时，还需要进步技术的帮助。所以，本题选择C。
