Saturday morning. In the supermarket with Mum. We're doing some shopping. Boring! People are walking around. I'm listening to music on my phone.
09:47
Hey, something is happening. A woman is sitting on a chair and she's playing the violin. What's this? It's a flash mob(快闪) in the supermarket!
09:48
Wow. This is fantastic! Now about ten men and women are standing here and they're playing music on violins and trumpets and things.
09:49
I'm looking at the other people in the supermarket. They're surprised like me. But they like the music. They aren't thinking about food now!
09:50
Now four people are singing! They're giving a concert(音乐会), but they aren't wearing special clothes. Why is this happening? I don't know!
09:51
Mum says that the music is Handel's. She isn't shopping now—she's standing with me and we're listening. I'm not bored now!
09:53
Lots of people are taking out their phones and recording the concert. Other people are posting things on the Internet, like me! And a little girl is dancing.
09:55
OK, it's over. All the people here are smiling and talking about the music. All the musicians and singers are leaving. What a great morning!

【分析】
首先通读全文，理清作者记录的超市快闪活动的时间线、人物行为及作者的情感变化。针对各题：20题需定位音乐会的起止时间计算时长；21题需查找原文中人们在音乐会期间的行为，逐一核对选项；22题需梳理作者从开始到结束的情感转变；23题需根据作者的情感变化推断后续可能的行为。
【解析】
20题：根据原文时间，音乐会从09:47开始，到09:55结束，时长为55-47=8分钟，故选C。
21题：原文提到人们的行为：“They like the music”对应①listening and watching；“Lots of people are taking out their phones and recording the concert”对应②recording the concert；“Other people are posting things on the Internet, like me”对应③posting pictures and videos；④writing music未提及，故①②③正确，选D。
22题：作者最初说“We're doing some shopping. Boring!”（无聊），看到快闪时说“They're surprised like me”（惊讶），最后说“What a great morning!”（开心），情感变化为bored→surprised→happy，选A。
23题：作者原本觉得超市购物无聊，因快闪活动变得开心，可推断之后可能喜欢来这里购物，选D。
