一、The Study of Chemistry 托福紅Delta聽力原文：

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 托福紅Delta聽力中文翻譯：

化學有時被稱為中心科學。這并不奇怪，因為我們周圍發(fā)生的大多數(shù)過程都涉及化學變化。這里只是其中的幾個：植物是通過把簡單的物質變成更復雜的物質來生長的。汽車里的鋼材生銹了。

雞蛋、糖、面粉和發(fā)酵粉混合并烘焙成蛋糕。發(fā)電廠的排放物會導致酸雨的形成。

化學是一門研究宇宙物質及其變化的科學。化學是我們努力創(chuàng)造新材料以改善生活的核心，例如，生產新能源?；瘜W家研究很多不同的東西。一些研究物質的基本粒子。其他人則在太空中尋找分子。還有一些人正在尋找控制威脅我們糧食供應或我們的疾病的方法。

但無論做什么工作，所有化學家都需要一定的技能。當我以前的學生回來拜訪我時，他們都說了同樣的話。他們說，他們成功的關鍵是了解基本原理、解決問題的能力和溝通能力。

有些人認為教育只是在大腦中儲存信息。很多學生只是想記住一系列的事實，然后在考試中把它們全吐出來。當然，將事實儲存在大腦中很重要?；瘜W語言一開始并不熟悉，你必須記住很多術語和定義。在交流之前，你必須先學習詞匯。記住事實很重要，但這只是教育的開始。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決問題。分析思維是教育的中心。

化學課程以難學著稱。

這并不奇怪，因為化學系統(tǒng)很復雜。不要指望馬上就能理解一切。只要記住，即使是有經驗的化學家也不是一開始就什么都懂。犯錯誤不是災難，但如果你不從錯誤中吸取教訓，就有可能是災難。

要解決一個典型的化學問題，你必須仔細閱讀給定的信息，并確定哪些信息真正重要。如果你不能做一道家庭作業(yè)題，不要只在書的后面查答案。這不是你學習的方式。如果你去黑客和審查相關材料，然后再試一次，你會學到更多。不要害怕與之斗爭。如果你確實在與這些問題作斗爭，那么就找一個同學一起工作，一起奮斗。事實上，這是一種了解科學家如何合作的好方法，嘗試一件事，然后再嘗試另一件事，直到找到解決方案。

學習化學需要時間。您可能一開始并不了解所有內容，并且可能無法在第一次嘗試時解決這些問題。當你犯錯時，你可能會感到沮喪。只要堅持工作，從錯誤中吸取教訓，你就會穩(wěn)步進步。
