题目内容
18.Our knowledge of the spaceis growing (grow) all the time.分析 我们对太空的知识一直在不断增长.
解答 答案:is growing
联系语境,根据关键词all the time指"一直",强调状态或动作的持续性;结合提示词grow为动词"增长",可知位于主语Our knowledge of the space 的后面应该作句子的谓语;结合题干可知此句是指"我们对太空的知识一直在不断增长",表示现阶段一直进行的动作,所以应用现在进行时来表达;其构成为:am/is/are+现在分词;主语为knowledg(知识)为不可数名词,故用单数is,grow的现在分词为growing.故填写:is growing
点评 此题考查现在进行时的用法.做题时联系前后语境结合关键词准确判断出句子所使用的时态是重点,之后结合相关时态的构成即可做出正确答案.此题注意主语的单复数的确定.
