With the world’ s population estimated to grow from six to nine billion by 2050, researchers, businesses and governments are already dealing with the impact, this increase will have on everything from food and water to infrastructure (基础设施) and jobs. Underling all this【C1】______ will be the demand for energy, which is expected to double over the next 40 years.
Finding the resources to meet this demand in a【C2】______ , sustainable way is the cornerstone (基石) of our nation’ s energy security, and will be one of the major【C3】______ of the 21st century. Alternative forms of energy-bio-fuels, wind and solar, to name a few—are【C4】______ being funded and developed, and will play a growing【C5】______ in the world’s energy supply. But experts say that even when【C6】______ , alternative energy sources will likely meet only about 30% of the world’ s energy needs by 2049.
For example, even with【C7】______ investments, such as the $ 93 million for wind energy development【C8】______ in the American Recovery and Reinvestment Act, important alternative energy sources such as wind and bio fuels【C9】______ only about 1% of the market today.
Energy and sustainability experts say the answer to our future energy needs will likely come from a lot of【C10】______ —both traditional and alternative.
[A] stable [B] solutions
[C] significant [D] role
[E] progress [F] marvelous
[G] included [H] growth
[I] exactly [J] consist
[K] comprise [L] competitions
[M] combined [N] challenges [O] certainly
【C7】
选项
答案
C
解析
根据空格前的介词with和其后的名词investment可知,此处需填入形容词,修饰investments。下文用such as举例说到9300万美元,由此可知投资数额是比较大的,significant“相当数量的”符合文意。marvelous多表示对事物的惊奇和赞美,意为“极好的;绝妙的”,故可排除。
