cIf you live in a region where winter weather is a regular risk,you are likely used topouring salt on your sidewalks.But how does it work?And how much salt do humans pouronto our planet's surface?The second question is easier to answer:a lot.Salt doesn't directly melt ice,nor does it make snow simply disappear.Instead itmakes water less likely to freeze in a phenomenon called freezing point depression.In thecase of simple rock salt,which is a rawer,less pure version of table salt,each molecule(splits into smaller elements.Normally,when water freezes into ice,its molecules lineup to form a stable,orderly structure.Salt interrupts the process,however,andtemperatures must drop lower to overcome that interruption and for freezing to occur.But if salt needs to interact with liquid water,how does it do anything whentemperatures are stubbornly below freezing,and water should already be in the form ofice?That's where cars help clear their own way by creating friction and,in turn,heat.The frictionallows for the ice that has already frozen to melt a little bit,making it unlikely to freezeBeyond rock salt's ability to clear icy streets,it can also be destructive.Chloride ions(can cause wear and tear on vehicles and facilities.Increasing chloride densities inNorth American lakes could begin to upset local ecology and degrade sources of drinkingwater.Many local governments are looking for alternatives to rock salt.Other salts such asmagnesium chloride and calcium chloride work in the same way as rock salt,and they'reperhaps even more efficient.Some experiments are testing other ice-preventing solutions,including those that contain sugars instead of or in addition to salts.Another approachrelies more heavily on sand,which can mechanically make roads safer.All of thisexperimentation is aimed at ensuring people can travel in any weather condition-aHerculean task when winter brings its worst.28.What's the purpose of the first sentence in Paragraph 2?A.To introduce the topic.B.To give some evidence.C.To define the phenomenon,D.To reveal the misconception.29.How does salt work to disturb the process of freezing?A.By lowering the temperature.B.By melting and splitting itself.C..By lining up to form a solid structure.D.By stopping the formation of the structure.英语试题第6页共12页
