It took a long time for the effective use of natural gas ______.A.making | B.being made | C.to make | D.to be made |
|
答案
D |
解析
试题分析:句意,能够有效地使用天然气,将花费很长的时间。分析句子结构,这里需要不定式作定语,“natural gas”与“to make”之间是被动关系,所以应该使用不定式的一般式的被动形式。 点评:不定式、动名词、现在分词、过去分词作定语的区别:不定式作定语往往表示未发生的动作或通常发生的动作,一般放在被修饰词后面;动名词作定语往往表示某种用途,一般放在被修饰词的前面;现在分词作定语表示主动、正在进行的动作,过去分词作定语表示被动或完成意义。 |
