找到可以也许不变而延续地知足这类需要的资本是咱们国度动力宁静的基石,也将是21世纪的首要挑衅之一。这些可替换动力,如生物燃料、风能和太阳能,肯定将会获得投资和成长,并且将在天下动力供应中表演着愈来愈主要的脚色。可是专家指出,即便将一切可替换动力都连系起来,到2050年,也许只能知足天下动力需要的30%摆布。
比方,即便有了大额投资,如《美国苏醒与再投资法案》经由过程的为开辟风能的9300万美圆投资,像风能和生物燃料如许的主要可替换动力却仅占了现今市场份额的l%。
动力和可延续成长方面的专家称,要知足未来的动力需要,能够要依靠于多种处置计划,既包罗传统动力又包罗可替换动力。
谜底及剖析
46.【谜底】H
【剖析】空格前面为唆使代词this,前面为谓语动词will be,由此可知空格中应填双数名词。this是对上文的归纳综合,指的应当是上文提到的生齿增添,故此处应填入与上文increase同义的词,growth合适辞意。
47.【谜底】A
【剖析】按照逗号前面的sustainable可知,此处需填入描述词,与sus.tainable并列配合润色way,且意义与sustainable近似。stable“不变的”与sustainable“可延续的”语义附近,合适语境,故选stable。
48.【谜底】N
【剖析】按照空格前的0ne of the major可揣度此处需填入名词的双数情势。上文提到动力需要不时增添,此空地点段的段末谈及可替换动力也许只能知足天下动力需要的30%摆布,因而可知,要找到充沛的动力是一种“挑衅”,challenges合适辞意。competitions多指人或机构为了某种好处而合作,此处不“掠取动力”这类语境,以是解除。
49.【谜底}o
【剖析】此处需填入副词,润色空格后的动词词组being funded and de—veloped。下文接着说的是可替换动力在天下动力供应中表演愈来愈主要的脚色,由此可揣度帮助成长可替换动力是理所固然的工作,故选certainly。此处填入备选的另外一个副词exactly(切确地,切确地)语义不通。
50.【谜底】D
【剖析】按照a growing可知空格处应填入名词的双数情势。play a…in提醒了此处选role,play a role in是牢固搭配,表现“在…中起感化”。
51.【谜底】M
【剖析】阐发句子布局可知,when指点的时候状语从句省略了主语和be动词,连系句意可知,空格处的单词与alternative energy SourceS是主动干系,故此处应填动词的曩昔分词情势。由句子粗心可揣度,此处所填的词有“合在一路,连系”的意义,故combined(使连系,连系)合适句意。
52.【谜底】c
【剖析】按照空格前的介词with和厥后的名词investment可知,此处需填人描述词,润色investments。下文用such as举例说到9300万美圆,由此可知投资数额是比拟大的,significant“相称数目的”合适辞意。marvelous多表现对事物的诧异和歌颂,意为“极好的;绝妙的”,故可解除。
53.【谜底】G
【剖析】此处需填入分词情势,该分词跟介词in搭配,作$93 million for wind energy development的后置定语。空后内容是一项法案,应当是风能开辟的投资被包罗在法案傍边,included合适句意,be included in表现“被包罗在内的”。
54.【谜底】K
【剖析】此处需填人谓语动词,连系双数情势的主语alternative energy sources和句末的today,可知此处应当是动词真相。comprise和con-sist均有“包罗,构成”之义,但consist需后接介词of能力跟宾语(此处1%是数词作宾语),故选comprise。
55.【谜底】B
【剖析】按照空格前的a lot of可知此处需填入名词的双数情势。The answer to…提醒此处有“处置…的方式”之意,solutions(处置方式,处置手腕)合适语义。
