一、The Study of Chemistry 托福红Delta听力原文:
Chemistry is sometimes called the central science.This isn’t surprising,since most of the processes going on around us involve chemical changes.Here are just a few of them:A plant grows by changing simple substances into more complex substances.The steel in a car rusts.
Eggs,sugar,flour,and baking powder are mixed and baked into a cake.Emissions from a power plant cause the formation of acid rain.
Chemistry is the science that deals with the materials of the universe and the changes these materials go through.Chemistry is at the heart of our efforts to create new materials to make our lives better—for example,to produce new sources of energy.Chemists work on a lot of different things.Some examine the fundamental particles of matter.Others are looking for molecules in space.Still others are looking for ways to control the diseases that threaten our food supply or us.
But whatever the work,all chemists need certain skills.When my former students come back to visit me,they all say the same thing.They say that what’s essential in their success is an understanding of the fundamentals,the ability to solve problems,and the ability to communicate.
Some people think education is just storing information in the brain.A lot of students just want to memorize lists of facts and then sort of spit it all out on tests.Of course,storing facts in the brain is important.The language of chemistry is unfamiliar at first,and you do have to memorize a lot of terms and definitions.You have to learn the vocabulary before you can communicate.Memorizing facts is important,but it’s just the beginning of education.Don’t stop there.Don’t be afraid to do some thinking of your own,and don’t be afraid to trust yourself to figure things out.Analytical thinking is the center of education.
Chemistry courses have a reputation for being difficult.
This isn’t surprising,since chemical systems are,well,complicated.Don’t expect to understand everything right away.Just remember that even experienced chemists don’t understand everything at first.It’s not a disaster to make a mistake,but it could be,if you don’t learn from your mistake.
To solve a typical chemistry problem,you have to go through the given information and decide what information is really important.If you can’t do one of the homework problems,don’t just look up the answer in the back of the book.That’s not how you learn.You’ll learn more if you go hack and review the relevant material,and then try the problem again.Don’t be afraid to struggle with it.If you do struggle with the problems,then find a classmate to work with,and struggle together.Actually,this is kind of a good way to learn about how scientists work together,trying one thing and then another until they come up with a solution.
It takes time to learn chemistry.You might not understand everything at first,and you might not be able to do the problems the first time you try.You might feel frustrated when you make a mistake.Just keep working—and learning from your mistakes—and you’ll make steady progress.
二、The Study of Chemistry 托福红Delta听力中文翻译:
化学有时被称为中心科学。这并不奇怪,因为我们周围发生的大多数过程都涉及化学变化。这里只是其中的几个:植物是通过把简单的物质变成更复杂的物质来生长的。汽车里的钢材生锈了。
鸡蛋、糖、面粉和发酵粉混合并烘焙成蛋糕。发电厂的排放物会导致酸雨的形成。
化学是一门研究宇宙物质及其变化的科学。化学是我们努力创造新材料以改善生活的核心,例如,生产新能源。化学家研究很多不同的东西。一些研究物质的基本粒子。其他人则在太空中寻找分子。还有一些人正在寻找控制威胁我们粮食供应或我们的疾病的方法。
但无论做什么工作,所有化学家都需要一定的技能。当我以前的学生回来拜访我时,他们都说了同样的话。他们说,他们成功的关键是了解基本原理、解决问题的能力和沟通能力。
有些人认为教育只是在大脑中储存信息。很多学生只是想记住一系列的事实,然后在考试中把它们全吐出来。当然,将事实储存在大脑中很重要。化学语言一开始并不熟悉,你必须记住很多术语和定义。在交流之前,你必须先学习词汇。记住事实很重要,但这只是教育的开始。不要就此止步。不要害怕自己思考,也不要害怕相信自己能解决问题。分析思维是教育的中心。
化学课程以难学著称。
这并不奇怪,因为化学系统很复杂。不要指望马上就能理解一切。只要记住,即使是有经验的化学家也不是一开始就什么都懂。犯错误不是灾难,但如果你不从错误中吸取教训,就有可能是灾难。
要解决一个典型的化学问题,你必须仔细阅读给定的信息,并确定哪些信息真正重要。如果你不能做一道家庭作业题,不要只在书的后面查答案。这不是你学习的方式。如果你去黑客和审查相关材料,然后再试一次,你会学到更多。不要害怕与之斗争。如果你确实在与这些问题作斗争,那么就找一个同学一起工作,一起奋斗。事实上,这是一种了解科学家如何合作的好方法,尝试一件事,然后再尝试另一件事,直到找到解决方案。
学习化学需要时间。您可能一开始并不了解所有内容,并且可能无法在第一次尝试时解决这些问题。当你犯错时,你可能会感到沮丧。只要坚持工作,从错误中吸取教训,你就会稳步进步。
