题目内容
8.A low-carbon(低碳)lifestyle has ______ effect on our daily life.People are paying more and more attention to saving ______ these days.( )| A. | the;energies | B. | a;energy | C. | an;energy |
分析 一种低碳的生活方式已经对我们的日常生活产生了影响.现在人们越来越重视节能.
解答 答案:C 此题考查冠词的用法.根据关键部分has ______ effect on 可知这里应该用固定短语have an effect on去完成,意为对…产生影响;effect是以元音音素开头的单词,所以用an;根据 saving ______ 并结合选项可知,因为energy(能源)是不可数名词,所以没有复数形式,仍然用原形,save energy意为"节能".综合起来,故选C.
点评 抓住句中的关键词利用其固定表达确定出冠词;本题还要注意名词的可数与不可数的问题.两者结合选出正确的答案.
