题目内容
15.When one'sconcentration(concentrate) is slipping,he may have a hard time writing or reading.分析 当一个人的注意力不集中时,他可能会很难去进行阅读或写作.
解答 答案:concentration
此处用在名词的所有格one's之后,在从句中作主语,意为:一个人的注意力,故用动词concentrate的名词形式;由于concentration在本句中表达的是抽象概念,因此它是不可数名词;故填concentration
点评 本题考查了名词的用法;做本题时,首先根据句意及空缺处在句中的位置,确定此处单词的词性;其次在确定了应填名词之后,还要考虑到名词的单复数;另外,本题还考查到了构词法的知识,因此在学习过程中,应注意总结构词方面的一些规律.
