【分析】本题考查现在进行时的相关句式转换,解题思路为:首先确定各句时态为现在进行时(结构:am/is/are + 动词现在分词),再根据不同题型要求调整be动词位置、添加否定词、选择合适疑问词或改写时态标志对应的动词形式。
【解析】1. 现在进行时的否定句需在be动词后加not,is与not缩写为isn't,后接动词现在分词doing,故填isn't doing。
2. 现在进行时的一般疑问句需将be动词are提前,主语the workers用代词they代替,否定回答为No, they aren't,故依次填Are; working; No; they aren't。
3. 画线部分in the park表地点,用疑问词Where提问,后接be动词are,再跟主语和动词现在分词flying,故填Where are; flying。
4. at the moment是现在进行时的标志,需将一般现在时的shares改为现在进行时is sharing,故填is sharing。
5. 画线部分writing a letter表动作,用疑问词What提问,后接be动词is,再跟主语和动词现在分词doing,故填What is; doing。
【答案】1. isn't doing 2. Are; working; No; they aren't 3. Where are; flying 4. is sharing 5. What is; doing
【知识点】现在进行时、英语句式转换、特殊疑问句
【点评】本题聚焦现在进行时的基础用法及句式转换,涵盖否定句、一般疑问句、特殊疑问句改写及时态替换,是初中英语的核心基础考点,需熟练掌握现在进行时的结构规则。
