The Study of Chemistry 托福紅Delta聽(tīng)力原文翻譯及問(wèn)題答案，今天中國(guó)教育在線就來(lái)為大家分析這個(gè)問(wèn)題。

一、The Study of Chemistry 托福紅Delta聽(tīng)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(tīng)力中文翻譯：

化學(xué)有時(shí)被稱(chēng)為中心科學(xué)。這并不奇怪，因?yàn)槲覀冎車(chē)l(fā)生的大多數(shù)過(guò)程都涉及化學(xué)變化。這里只是其中的幾個(gè)：植物是通過(guò)把簡(jiǎn)單的物質(zhì)變成更復(fù)雜的物質(zhì)來(lái)生長(zhǎng)的。汽車(chē)?yán)锏匿摬纳P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(huì)導(dǎo)致酸雨的形成。

化學(xué)是一門(mén)研究宇宙物質(zhì)及其變化的科學(xué)?；瘜W(xué)是我們努力創(chuàng)造新材料以改善生活的核心，例如，生產(chǎn)新能源?；瘜W(xué)家研究很多不同的東西。一些研究物質(zhì)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(yīng)或我們的疾病的方法。

但無(wú)論做什么工作，所有化學(xué)家都需要一定的技能。當(dāng)我以前的學(xué)生回來(lái)拜訪我時(shí)，他們都說(shuō)了同樣的話(huà)。他們說(shuō)，他們成功的關(guān)鍵是了解基本原理、解決問(wèn)題的能力和溝通能力。

有些人認(rèn)為教育只是在大腦中儲(chǔ)存信息。很多學(xué)生只是想記住一系列的事實(shí)，然后在考試中把它們?nèi)鲁鰜?lái)。當(dāng)然，將事實(shí)儲(chǔ)存在大腦中很重要?；瘜W(xué)語(yǔ)言一開(kāi)始并不熟悉，你必須記住很多術(shù)語(yǔ)和定義。在交流之前，你必須先學(xué)習(xí)詞匯。記住事實(shí)很重要，但這只是教育的開(kāi)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(wèn)題。分析思維是教育的中心。

化學(xué)課程以難學(xué)著稱(chēng)。

這并不奇怪，因?yàn)榛瘜W(xué)系統(tǒng)很復(fù)雜。不要指望馬上就能理解一切。只要記住，即使是有經(jīng)驗(yàn)的化學(xué)家也不是一開(kāi)始就什么都懂。犯錯(cuò)誤不是災(zāi)難，但如果你不從錯(cuò)誤中吸取教訓(xùn)，就有可能是災(zāi)難。

要解決一個(gè)典型的化學(xué)問(wèn)題，你必須仔細(xì)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(shū)的后面查答案。這不是你學(xué)習(xí)的方式。如果你去黑客和審查相關(guān)材料，然后再試一次，你會(huì)學(xué)到更多。不要害怕與之斗爭(zhēng)。如果你確實(shí)在與這些問(wèn)題作斗爭(zhēng)，那么就找一個(gè)同學(xué)一起工作，一起奮斗。事實(shí)上，這是一種了解科學(xué)家如何合作的好方法，嘗試一件事，然后再?lài)L試另一件事，直到找到解決方案。

學(xué)習(xí)化學(xué)需要時(shí)間。您可能一開(kāi)始并不了解所有內(nèi)容，并且可能無(wú)法在第一次嘗試時(shí)解決這些問(wèn)題。當(dāng)你犯錯(cuò)時(shí)，你可能會(huì)感到沮喪。只要堅(jiān)持工作，從錯(cuò)誤中吸取教訓(xùn)，你就會(huì)穩(wěn)步進(jìn)步。
