七、任务型阅读
Mr. Guo is a teacher from Xi’an. He asked his students to hand in their homework through a QR code (二维码). “We spent an hour or two in class learning how to generate (使产生) the codes, and in the end everything gets easier.” Said Guo, “When students finish the homework, they keep it on WeChat. Then, each student makes his own QR code and gives it to me. So I can check their work anywhere using my computer or telephone.”
The QR codes can be sent to Mr. Guo by email, QQ and WeChat. When Guo scans (扫描) his students' QR codes, their homework appears on his phone. He finds that their homework becomes more creative, with many pictures, music and even videos.
Guo's students like the new way and think it is interesting. “We are living in the information age. Many students like to work with computers, which makes learning more fun.” Said Tingting, a student of Guo's.
“The paper is not easy to keep, but the code is easy to keep and share.” Guo said, “It is worth trying to use new technology in education. Education itself is a kind of creation. I don't want my students to fall behind the times.”
However, some parents are worried. They are afraid that their children will spend too much time on computers and less time communicating with teachers. But in fact, it's unnecessary. Students still need to look up information in books and write it down when they do their homework. They only use the codes when they hand in their work, which doesn't take them too much time. Also for teachers, it allows them to check the students' work at any time. And it's also an easy way to share homework with other students.

5．（2024·山东泰安·二模）学习酸、碱的知识后，小芳构建了物质之间的反应关系图，甲、乙、丙是三种初中常见物质，其中甲为黑色固体，乙、丙为氧化物，如图连线两端的物质均能发生反应。下列说法正确的是
A．甲物质可以通过金属矿石的冶炼获得
B．称生石灰，可用于配制波尔多液
C．若乙物质中有铁元素，乙与稀盐酸反应得到溶液一定呈浅绿色
D．甲与丙反应过程会吸热，甲可以通过化合或置换反应转化为丙
【答案】D
【分析】甲、乙、丙是三种初中常见物质，其中甲为黑色固体，乙、丙为氧化物，甲能和乙、丙反应，乙能和盐酸反应，丙能和氢氧化钙反应，则甲是碳，乙可以是氧化铜、氧化铁等，丙是二氧化碳，代入验证，推论合理。

综合强化
根据1 mol CxHyOz完全燃烧消耗氧气
的量为(x+-) mol知，1 mol C3H6O3
完全燃烧消耗O2为(3+-) mol=3 mol，
同理，1 mol C2H6O和1 mol C2H4完全燃烧消耗O2均为3 mol，所以三者无论以何种比例混合，完全燃烧消耗氧气的物质的量均为3 mol，D正确。
