The trend of having meals alone. The importance of self-reflection.
The stress from working overtime. The advantage of wireless technology.
(2021·新高考Ⅰ卷)
When the explorers first set foot upon the continent of North America, the skies and lands were alive with an astonishing variety of wildlife.Native Americans had taken care of these precious natural resources wisely.Unfortunately, it took the explorers and the settlers who followed only a few decades to decimate a large part of these resources.Millions of waterfowl (水禽) were killed at the hands of market hunters and a handful of overly ambitious sportsmen.Millions of acres of wetlands were dried to feed and house the ever-increasing populations, greatly reducing waterfowl habitat (栖息地).
In 1934, with the passage of the Migratory Bird Hunting Stamp Act(Act), an increasingly concerned nation took firm action to stop the destruction of migratory (迁徙的) waterfowl and the wetlands so vital to their survival.Under this Act, all waterfowl hunters 16 years of age and over must annually purchase and carry a Federal Duck Stamp.The very first Federal Duck Stamp was designed by J.N.“Ding” Darling, a political cartoonist from Des Moines, Iowa, who at that time was appointed by President Franklin Roosevelt as Director of the Bureau of Biological Survey. Hunters willingly pay the stamp price to ensure the survival of our natural resources.
About 98 cents of every duck stamp dollar goes directly into the Migratory Bird Conservation Fund to purchase wetlands and wildlife habitat for inclusion into the National Wildlife Refuge System—a fact that ensures this land will be protected and available for all generations to come.Since 1934, better than half a billion dollars has gone into that Fund to purchase more than 5 million acres of habitat.Little wonder the Federal Duck Stamp Program has been called one of the most successful conservation programs ever initiated.
5.What was a cause of the waterfowl population decline in North America

Ⅳ：
(1) 。
(2)若仅考虑主反应Ⅰ，一定温度下，向恒压密闭容器中通入一定量丙烷，反应后测得的组分的平衡压强（即组分的物质的量分数×总压）为：、。
①该温度下反应的平衡常数的数值为 。（单位用MPa，保留3位有效数字）
②平衡时丙烷的转化率为 。
(3)对于反应Ⅰ，某课题组研究设计一套丙烷连续催化脱氢装置如图。
①将1 mol丙烷（温度为590 ℃）以恒定的流速依次逐个通过三个相同的装置，画出丙烯的产率随着时间的变化阶段二和阶段三的图像 。（每个阶段反应均未达到平衡）


A.铝热反应
B.Ba(OH),·8H,O和NHCI的混合物溶于水
C.灼热的木炭与CuO反应
D.镁条在CO2中燃烧
【答案】C
【解析】A.铝热反应属于放热反应，故△H<0,故A错误：B.Ba(OH),8H,O与NH,CI
溶于水反应吸收热量，属于吸热反应，但反应过程中元素化合价没有发生变化，不属于氧化
