（转自临沂师范学院数学系）

world is pretty complicated today compared with what it was forty years ago. And it's
getting more so all the time.
今天的世界与40年前的世界相比复杂多了。而且还会越来越复杂。
We have to have more and more specially trained people.
我们必须拥有越来越多的经过专门训练的人才。
We need math to solve the tough problems of science.
我们需要数学来解答科学上的难题。
We need them to find new ways to conquer disease, to design the machines of industry and the
laborsaving gadgets of the home.
我们需要数学来找到攻克疑难病症的新方法以及设计工业机器和节省家庭劳动的小发明的< br>新思路。
And we need them more and more for the ordinary things of everyday life.
我们还越来越需要数学来得到日常生活中的常用东西。

takes special training to be a good carpenter, or plumber, or car mechanic.
要当一名好的木工、管子工或汽车修理工需经过专门训练。
Jobs in electronics require even greater skills.
电子技术方面的工作需要更多的技能。
We used to think a radio repairman had to have a pretty thorough kind of training.
我们通常认为修理收音机(的人)需全面良好的训练。
But it's even tougher to be a television repairman.
但修理电视机(的人)就更复杂了。

of you are probably thinking,
你们中有些人可能在想：“工程技术人员学习数学是对的.
But suppose I want to be an artist, a druggist, or a nurse. Suppose I want to go in business for
myself. 但是假如我想
当艺术家、药剂师、护士，假如我本人想经商，
What good will math do me?
数学对我有什么帮助呢?” 好，让我们看看吧。

artists today are in what is called applied art.
今天的许多艺术家都是所谓的应用艺术家。
They use their ability in advertising, interior decoration, or some similar job.
他们把能力用在广告、室内装璜或某种类似的工作上。
But people in business who hire the artists for that kind of work say that simple artistic ability is
not enough.
但雇佣艺术家来做上述工作的商界人士说，仅仅有艺术才能是不够的。
There are lots of young people who have that. But not enough of them know anything about
physics, or mechanical things, or math.
许多青年人有艺术才能，但其中懂物理、机械或数学的人不太多。

be a druggist you have to study chemistry.
要成为药剂师你必须学习化学。
You can't learn chemistry without knowing something about algebra.
你不懂代数就学不了化学。
How about a nurse?
要当护士又该如何?
One of the required subjects in a course of nursing is known as materia medica.
培养护士过程中必修课之一是药物学。
In materia medica you'll learn how to figure out doses and prepare medicines.
在药物学课上你会学会怎样计算出药的剂量和配制药。
Algebra is important in doing the figuring.
做这些计算代数是重要的。
Too many student nurses flunk out of the course because their math is weak.
许许多多学护士的学生因为数学底子太差考试不及格而退学。

's the same with many trades.
许多手工艺也是这样。
If you want to be a draftsman, a machinist, a molder, or a patternmaker, you'll need algebra and
geometry and even trigonometry.
如果你想成为手工艺人、缝纫工、造型工或制模工，你需要代数和几何，甚至三角。

if you want to go into business for yourself, you'll need math.
即使你本人想从商，你也需要数学。
Business today, whether it's running a little gas station or a big factory, takes good management.
今天的工商企业，不论是经营一个小的加油站还是管理一座大工厂，都需要良好的管理。

良好的管理要利用数学。

those who are going to keep up the wonderful progress being made in science and
engineering need math more than anyone else does.
那些想继续保持在科学和工程上已取得惊人进步的人比其他人更需要数学。

've read about those wonderful computers that used today.
你已经读过有关今天使用的威力强大的计算机的导报。
These are machines that work by electronics to do all sorts of complicated problems in
mathematics at terrific speeds.
这些计算机是利用电子技术操作的机器，能以惊人的速度解决各种复杂的数学问题。
Maybe you think we should let those machines do our math problem.
也许你会想，我们应让这些机器为我们做数学题。
If you do,you don't understand the way computers work.
如果你这样想了，你就不懂计算机的工作方法了。

10.A computer is not better than the human mind that controls it.
计算机根本不比控制它的人脑强。
Mathematician has to run it.
数学工作者必须操作计算机。
He has to analyze the problem and set it up. 他必须分析并提出问题。
Then he must feed the data into the machine before the machine can solve the problem.
然后，他必须把数据输进计算机之后，计算机才能解决这个问题。
Computers are a big help. They can make calculations faster than a man they can't do our
math for us.
计算机是个大帮手。 它比人算的快。 但它不能为我们解数学题。

's something else you shouldn't forget.
还有些事你不该忘记。
there are lots of times when more math would help you in your everyday affairs.
你在日常事物中需要更多数学帮助的时候太多了。
A famous British mathematician points out that we live surrounded by figures.
一位著名的英国数学家指出，我们生活在被数学包围的环境里。
Think of railway timetables, unemployment insurance, taxes, schedules of working hours, speed
limits, calories,
automobile and truck weights, temperatures, rainfall, miles per gallon, electricity and gas meter
readings, bank
interest, parcel post and freight rates, and so on.
