六、任务型阅读。
阅读短文，回答下列问题。
Tourism is causing damage(损坏) to many cultural relics(遗迹). To better protect them，grotto(洞穴) temple workers have been asked to do research and decide how many daily visitors they can safely receive.
Causes of the damage
Tourists' poor behaviour，like dropping litter around，can lead to problems and damage relics.
Over many centuries，the ancient rocks that make up these grottoes slowly corrode(侵蚀) because of the acidic(酸性的) content of air，water and microorganisms(微生物). But when they are open to the public，the corrosion process speeds up.
According to a study by the China University of Geosciences，the carbon dioxide(二氧化碳) that visitors breathe out has made the air more acidic at the Longmen Grottoes. At the Mogao Grottoes in Gansu，researchers found that visitors often bring in microorganisms. Even their body heat can increase the caves' temperature. All of these things can harm the relics inside.
Online tours offer the other choice
To keep a balance between protecting relics and educating the public，some grotto sites have created their own digital(数字化的) museums.
The Mogao Grottoes in Dunhuang，Gansu
If you want to see the beautiful statues and paintings of the Mogao Grottoes，just go to e-dunhuang.com. You can learn all about the stories behind the relics with this "virtual(虚拟的) tour guide".
The Maiji Mountain Grottoes in Tianshui，Gansu
Visit mjssk.cn and you'll not only get travel information about the Maiji Mountain Grottoes but also collect pictures from the site. There are also descriptions of important works of art.
1. Why does grotto rock corrosion speed up?
2. What does mjssk.cn offer to grotto visitors?
3. What do you think of online grotto tours?

解析
【分析】
做这道任务型阅读时，首先可以先通读题干划出每道题的核心关键词，再带着关键词回到原文对应段落定位信息：第1题的关键词是grotto rock corrosion speed up，直接定位到“损坏的原因”板块找对应表述；第2题的关键词是网址mjssk.cn，定位到麦积山石窟的介绍段落提取所有相关服务内容；第3题是开放性问题，结合文中提到的线上游览的优势，结合自身理解合理作答即可，不需要完全拘泥于固定表述，言之有理就符合要求。
【解析】
1. 定位到原文Causes of the damage板块的第二段内容：数世纪来组成石窟的古岩石本就会因空气、水和微生物的酸性成分缓慢侵蚀，但石窟对公众开放后，侵蚀进程就加快了，直接提取对应的原因即可得到答案。
2. 定位到麦积山石窟的线上游览介绍段落，原文明确说明访问mjssk.cn可以获取麦积山石窟的旅游信息、收集景点图片，还能看到重要艺术作品的介绍，将这几部分内容整合就是完整答案。
3. 本题为开放性设问，结合文中提到的线上游览可以平衡文物保护和公众科普的作用，既可以从保护文物的角度肯定它的优势，也可以从游览体验的角度说出它的不足，表述通顺逻辑合理即可。
【答案】
1. Because the grottoes are open to the public.
2. Travel information, pictures from the site and descriptions of important works of art.
3. They help keep relics safe. /They are easy but not as fun. (言之有理即可)
【知识点】
细节信息提取、阅读信息整合、开放性表达
【点评】
本题难度梯度设置合理，前两道题属于原文直接可定位的细节题，重点考察学生快速查找文本信息的能力，第三道开放题引导学生结合文本内容思考文物保护的创新形式，兼顾考察学生的信息理解能力和独立思辨能力，整体难度不高，适合巩固任务型阅读的基础解题技巧。
【难度系数】
