Part2 提升能力 五、阅读理解 During the hot summer，we can easily cool off with air conditioners.But how did ancient people cool off without modern technologies？ As early as the Pre-Qin Dynasty，people used natural ice.The emperor of the Zhou Dynasty even set up the “ice administration” which had 80workers to collect and store ice in winter. A cooling tool often used was the “Jian”—a container (容器) filled with ice.By placing wine or fruit inside and closing the lid，drinks would become just as cool as they are in a modern fridge. Common people without the “Jian” turned to wells for help.During the Qin and Han dynasties，families put food baskets down into wells with ropes，using the underground air to cool the food.Well water itself was also the best drink in summer. For personal comfort，common people liked using fans and bamboo mats on their beds.These things could take away heat quickly and help them stay cool while sleeping.The rich and officials had other fancy choices.They preferred sleeping on the porcelain (瓷器) pillows and hanging the soft-mist silk over their beds to keep outdoor heat out. From these cooling practices，it’s clear that ancient people beat the heat with nature-friendly cleverness.They turned summer into an acceptable season using wisdom instead of technology.Aren’t you also amazed by the ancient people’s wisdom for cooling off？ 20.(　　) What can we know about the “ice administration” from the text？ A.It was set up by common people to make ice. B.It had workers for collecting and storing ice. C.It sold ice to the rich and officials. D.It provided ice for people all year round. 21.(　　) What was the “Jian” mainly used for in ancient times？ A.Making ice with its lid. B.Keeping food warm in winter. C.Cooling drinks or fruit with ice inside. D.Getting water from wells. 22.(　　) Which sentence uses “fancy” with the same meaning as the underlined word？ fancy /ˈfænsi/ ①自认为是 ②花哨的 ③昂贵的 ④想象的事物 A.My mum said no to the fancy toy car—I could get a cheaper one instead. B.His dream of becoming a successful man overnight is just a fancy—he never works hard for it. C.My little brother always likes to fancy himself as a superhero. D.She’s over 50 now.Such fancy clothes suit the young，not her anymore. 六、补全对话 根据下面的对话情景，在空白处填入一个适当的句子，使对话的意思连贯、完整。 A：How do you like the science fair？ B：23.____________________________ So many inventions are shown in it.
