fish，the antarctic cod.for forty years scientists have been curious about that fish.how does it live where most fish would freeze to death？it must have some secret.the antarctic is not a comfortable place to work and research has been slow.now it seems we have an answer.research was begun by cutting holes in the ice and catching the fish.scientists studied the fishs blood and measured its freezing point.the fish were taken from sea water that had a temperature of 1.88 and many tiny pieces of ice floating in it.the blood of the fish did not begin to freeze until its temperature was lowered to2.05.that small difference is enough for the fish to live at the freezing temperature of the icesalt mixture.the scientists next research job was clear：find out what in the fishs blood kept it from freezing.their search led to some really strange thing made up of a protein(蛋白质) never before seen in the blood of a fish.when it was removed，the blood froze at sea water temperature.when it was put back，the blood again had its antifreeze quality and a lowered freezing point.study showed that it is an unusual kind of protein.it has many small sugar molecules(分子) held in special positions within each big protein molecule.because of its sugar content，it is called a glycoprotein.so it has come to be called the antifreeze fish glycoprotein，or afgp.【语篇解读】你了解 the antarctic

drawer：collecttake out everything and put it in a pile.empty the entire drawer，and pile it all on a counter or a table.take everything out，down to the last paper clip.choosepick out only the few things you love and use and those are important to you.just sort through the pile，picking out the really necessary things.be very selective.put the important things you pick out into a separate，smaller pile.eliminatetoss the rest out.you know youll never need those things again.dont be sentimental with this step.either throw everything into a big rubbish bag, or find a new home for some of the items if you think someone might have a use for themdonate them to charity or give them to a friend who would love them.and yes，you have to toss out all the chopsticks.organizeput back the necessary things, neatly, with space around things. clean the drawer out first, of course, and put the very small pile of things you chose back in the drawer, grouping like things together and leaving space around the groups. having space around things makes everything look neater and simpler.thats it.you now have a very nice drawer, with a much less funky smell.this simple method can be applied to every area of your life. my suggestion is to focus on one area at a time，apply the method, and then move to the next area.so, if you just wanted to simplify a couple areas of your life，you could focus on one per week, but if you wanted to simplify your entire life, you would do one area every couple of days until youre done.【语篇解读】本文是说明文。如何使自己的抽屉更整洁，该文章提供了一系列的方法，而这些方法也适用于我们生活的各个方面。5which one is not
