A Jenny is talking to her father about what he did for fun as a child. Complete the conversation with the correct forms of the words in brackets. Add *not* if necessary.
Jenny: Dad, I was just thinking about how different things are now with all our modern technology. What did you do for fun as a child?
Dad: I did very different things from you. It seems like children’s activities (1) (change) quite a bit since I was young. When I was a child, I often ran around outside with my friends until after dark! We loved to catch insects too.
Jenny: Hmm … my friends and I (2) never (catch) insects! We sometimes go to an escape room together, but not very often. In fact, we (3) (do) that for months! Instead, we usually take selfies and share them with each other.
Dad: I guess technology (4) (make) a big difference to the way kids play in recent years. Ever since digital devices became popular, kids (5) (enjoy) spending time indoors. (6)  you ever (wonder) if that’s really a good thing?
Jenny: Well … I (7) never (think) about it before. You’re right—I (8) (spend) much time looking at screens recently. It’s time for me—and my friends—to get outside and enjoy nature around us!

这道题考查现在完成时的综合运用，解题关键是根据时间状语（如since, for months, in recent years, ever, before, recently等）和语境判断时态，同时注意现在完成时的肯定、否定及疑问形式的结构：肯定式为have/has+过去分词，否定式为have/has not+过去分词，一般疑问句需将have/has提前。具体思路如下：
1. 第(1)空：since引导时间状语从句，主句要用现在完成时，主语“children’s activities”是复数，所以用have+过去分词形式。
2. 第(2)空：never是现在完成时的标志词，主语“my friends and I”是复数，用have+过去分词。
3. 第(3)空：“for months”是现在完成时的时间状语，结合语境“我们好几个月没做密室逃脱了”，要用否定形式，主语是we，所以用haven't+过去分词。
4. 第(4)空：“in recent years”是现在完成时标志，主语“technology”是不可数名词，用has+过去分词。
5. 第(5)空：Ever since引导时间状语从句，主句用现在完成时，主语“kids”是复数，用have+过去分词。
6. 第(6)空：ever是现在完成时标志，此处是一般疑问句，主语是you，需将have提前并变为否定形式（结合语境是询问是否曾疑惑），所以用Haven't+主语+过去分词。
7. 第(7)空：before是现在完成时标志，never提示用现在完成时，主语是I，用have+过去分词。
8. 第(8)空：recently是现在完成时标志，主语是I，用have+过去分词。
【解析】
1. 第(1)空：根据“since I was young”这一现在完成时的标志状语，主语“children’s activities”为复数，所以填have changed。
2. 第(2)空：never是现在完成时的标志词，主语“my friends and I”是复数，现在完成时结构为have+过去分词，catch的过去分词是caught，所以填have; caught。
3. 第(3)空：“for months”表示一段时间，是现在完成时的时间状语，结合语境“我们好几个月没做那件事了”，要用否定形式，do的过去分词是done，主语是we，所以填haven't done。
4. 第(4)空：“in recent years”是现在完成时的标志，主语“technology”是不可数名词，现在完成时用has+过去分词，make的过去分词是made，所以填has made。
5. 第(5)空：“Ever since digital devices became popular”引导时间状语从句，主句要用现在完成时，主语“kids”是复数，enjoy的过去分词是enjoyed，所以填have enjoyed。
6. 第(6)空：ever是现在完成时的标志，此处是一般疑问句，主语是you，现在完成时的一般疑问句需将have提前，结合语境是询问“你难道不曾疑惑过吗”，所以用否定式的一般疑问句，填Haven't; wondered。
7. 第(7)空：before是现在完成时的标志词，never提示用现在完成时，主语是I，think的过去分词是thought，所以填have; thought。
8. 第(8)空：recently是现在完成时的标志，主语是I，spend的过去分词是spent，所以填have spent。
【答案】
1. have changed 2. have; caught 3. haven't done 4. has made 5. have enjoyed 6. Haven't; wondered 7. have; thought 8. have spent
【知识点】
1. 现在完成时结构
2. 现在完成时标志词
3. 现在完成时的否定与疑问形式
【点评】
本题围绕“童年娱乐方式对比”的对话语境，全面考查现在完成时的多种应用场景，涵盖肯定、否定、疑问三种形式，需要学生准确识别since、for、ever、recently等现在完成时标志词，并结合语境判断是否需要使用否定形式，对学生的时态运用能力有较好的检测作用。
