Last October, Grandpa Zhang from Henan joined a tour group for older people. The group visited six European countries in 12 days. More than 40 people were in the group with him. He came back to China on November 6th.

During the trip in Paris, Zhang took some photos. He did not use any beauty filters (美妆滤镜) or special angles. He just asked other tourists to take his photos quickly.

After returning to China, Zhang’s photos suddenly became very popular online. People joked the Eiffel Tower looked like a “wire tower” and the Seine River (a famous river in Paris) looked like a “ditch (水沟)”. The topic “Grandpa’s simple photos of Paris” became a hot topic online.

1.1. When did Grandpa Zhang start his trip to Europe?

A In October.

B In November.

C In December.

D In January.

解析：选A。A 细节理解题。文章开篇直接给出关键信息 “Last October, Grandpa Zhang from Henan joined a tour group for older people. The group visited six European countries...”，明确张大爷是在去年十月加入赴欧洲的旅行团，因此出发时间为十月。B 选项（十一月）是他回国的时间，C、D 选项在文中无对应信息，均排除。故选A。

2.2. Who helped take photos for Zhang in Paris?

A His family.

B A tour guide.

C Other tourists.

D A French friend.

解析：选C。C 细节理解题。文章第二段中描述：“He just asked other tourists to take his photos quickly.”，说明张大爷是请其他游客帮他拍照。选项A、B、D在文章中均未提及，因此正确答案为C。

3.3. Why did Zhang’s photos get popular online?

A They used filters and special angles.

B They looked very real and simple.

C They showed famous places clearly.

D They were taken by a professional.

解析：选B。B推理判断题。文章第二段提到张大爷没有使用美妆滤镜或特殊角度，只是快速拍照；第三段指出照片在网上流行后，人们开玩笑说埃菲尔铁塔像“电线塔”、塞纳河像“沟渠”，这暗示照片真实、简单、未加修饰，从而吸引了关注。选项A与文章内容相反；选项C和D在文章中未直接体现，因此通过推理得出正确答案为B。

4.4. What did Grandpa Zhang say about his photos?

A He thinks they are ordinary.

B He knows why they are famous.

C It was raining when he took them.

D He wants to be a photographer.

解析：选C。C 细节理解题。文章最后一句明确提到 “but it rained on the day he took the photos”，这是张大爷提及的与照片相关的内容。A 选项 “他认为照片很普通” 在原文中未直接表述；B 选项与原文 “Zhang said he didn’t know why he became famous.” 矛盾；D 选项 “他想成为摄影师” 属于无中生有，因此 A、B、D 均排除。因此正确答案为C。

5.5. What is the main idea of the text?

A A boring European trip.

B A hot online live talk.

C A rainy day in Paris.

D A grandpa’s popular photos.

解析：选D。D 主旨大意题。文章主要围绕张大爷的欧洲旅行照片展开：他拍了简单真实的照片，这些照片在网上意外走红，并引发了在线直播讨论。全文核心是张大爷的照片变得热门，而不是侧重于旅行本身、直播谈话或天气。选项A、B、C都只是文章中的细节，不能概括全文主旨，因此通过综合推理得出正确答案为D。
