1. it 作形式主语的意义：当主语部分相对于谓语部分而言太长时，常把主语部分移到句尾，在主语的位置放上it。
2. it 没有具体的意义，仅用于使句子显得平稳，不头重脚轻。
3. it 作形式主语时常代替三种语法结构：1.________________。
4. it 代替不定式(短语)作形式主语的常见句型：2.________________

辨析：
"It +be+形容词 +for sb. to do sth."与"It+be+形容词 +of sb. to do sth."

My 20-year-old daughter, Allison, living in Philadelphia, sent me a text the other day: "I need socks and shampoo." She was actually asking me to 1 those items for her, but I 2 she was playing a cellphone game. I decide not to be a helicopter 3 , because experience as a mother and professor has taught me how badly that can result.

Another mother checks her son's credit card daily. However, I never do that. My daughters only come to me with 13 things that need my decision, and I think that's because I give them space.
Many parents try to find out if their kids are 14 something from them. But we have to learn to respect boundaries, even when technology is so 15 . So I am going to do my best not to be a helicopter parent.

答案：twenties; where; stood; hosted; sharing; director; to; the; be made; to tell
解析：①句意为：这名来自阿富汗的20多岁的男子通常会沿着亮马河晨跑，开始一天的生活。in one's twenties为固定表达，意为“在某人二十多岁的时候”，故填 twenties。
②句意为：早上的例行锻炼结束后，他会去一个著名的地方一三里屯，他在那里做生意。设空处引导的是定语从句，从句中不缺主语或宾语，先行词place是地方，因此设空处用关系副词where, 在从句中作地点状语。
③句意为：最近艾哈迈德扎伊的日常瞬间被制作成了一个短视频，在之前举办的“爱上北京的100个理由”短视频比赛中脱颖而出。由in the previous activity 可知，句子描述过去的事情，时态用一般过去时，stand与主语that之间为主动关系，故填 stood。
④句意为：该活动由北京市人民政府新闻办公室主办，自2020年起每年举办一届。本句谓语是 has been held, 因此设空处要使用非谓语动词；event 和 host之间是逻辑上的被动关系，因此设空处应用过去分词，故填hosted。
⑤句意为：“‘爱上北京的100个理由’不仅仅是一个短视频比赛，还是一个分享故事的平台。”北京市人民政府新闻办公室主任徐和建说。for是介词，其后跟动名词作宾语，因此设空处填sharing。

⑨句意为：未来将更加努力适应移动化、社会化、视觉化的国际传播趋势，更好地讲述北京的故事。efforts 和make之间是被动关系，因此此处用被动语态，will 是情态动词，因此设空处用动词原形。故填be made。
⑩句意见上一题解析。根据句意，此处表目的，故应用不定式作目的状语。故填 to tell。
