The Basics of Math—Made Clear
Basic Math introduces students to the basic concepts of mathematics, as well as the fundamentals of more tricky areas. These 30 fantastic lectures are designed to provide students with an understanding of arithmetic and to prepare them for Algebra(代数) and beyond.
The lessons in Basic Math cover every basic aspect of arithmetic. They also look into exponents(指数), the order of operations, and square roots. In addition to learning how to perform various mathematical operations, students discover why these operations work, how a particular mathematical topic relates to other branches of mathematics, and how these operations can be used practically.
Basic Math starts from the relatively easier concepts and gradually moves on to the more troublesome ones, so as to allow for steady and sure understanding of the material by students. The lectures offer students the chance to “make sense” of mathematical knowledge that may have seemed so frightening. They also help students prepare for college mathematics and overcome their anxiety about this amazing—and completely understandable—field of study.
By the conclusion of the course, students will have improved their understanding of basic math. They will be able to clear away the mystery(神秘性) of mathematics and face their studies with more confidence than they ever imagined. In addition, they will strengthen their ability to accept new and exciting mathematical challenges.
Professor H. Siegel, honored by Kentucky Educational Television as “the best math teacher in America,” is a devoted teacher and has a gift for explaining mathematical concepts in ways that make them seem clear and obvious.

Science。And technology students in China and the US have a1ong way to go before they call develop a deep understanding of scientific reasoning,researchers have found.
As part of a research to compare science education in China and the US,LeiBao,a professor
from the Departmenr of Physics of the Ohio State University, gave 5,760;freshmen in three US and four Chin
ese univeristies two tests to evaluate content knowledge and another to assess scientific reasoning
Though Chinese students did better than their US counterparts in the first two tests that
Emphasized on learning facts,both groups “scored relatively poorly”on the third test,designed to
Assess their ability ot systmatically explore a problem , the results showed.
Lei Bao said that the finding challenges conventional wisdom,which holds that teaching
science facts will improve students’reasoning ability.“Our study shows that ,contrary to what many people would expect,even when students are thoroughly taught the facts,they don’t necessarily develop the reasoning skills they need io succeed.’’IBao said:‘“Because students need both knowledge and reasoning,we need to explore teaching methods that target both.”
‘The current education systems and asessment of China and the US do not emphasize on deep understanding of scientific reasoning in the disciplines of science;technology,engineering and mathematics(STEM),the study concluded.
Bao explained that reasoning is good skill for everyone topossess-not just scientists and
engineers:The general public also need good reasoning skills in order to correctly interpret
scientific findings and think rationally.STEM students need to excael at scientific reasoning in order to handle open-ended real-world tasks in their future careers in science and engineering.
How to boost scientific reasoning?The study suggests that educators must go beyond teaching science facts if they hope to boost students’reasoning ability.Bao points to inquiry-based leaming.where students work in groups,question teachers and design their owu investigations.This teaching technique is growing in popularity worldwide.
67.According to the research,we know that
A.Chinese students and their US counterparts did poorly in the first two tests
B.Chinese students did beaer than their US counterparts in alI the three tests
C.Chinese students did beaer than their US counterparts in the first two tests ‘
D.US students did beaer than their Chinese counterparts in the third test
68.The conventional wisdom holds that.
A.the more facts~tudents are taught,the more reasoning skills they will acquire
B.the general public also need reasoning skills to interpret scientific findings
C.to boost students’reasoning ability,educators must explore teaching methods
D.the current education Systems are harmful to improve students’reasoning ability
69.Based on the study,what will be done to improve students’reasoning ability?
A.To improve teaching techniques. B.To better students’learning conditions.
C.To teach students more science facts. D.To offer students more tests.
70.The underlined phrase“excel at”in Paragraph 6 probably means.

1n 2007.five young people in the American state of Massachusetts developed an idea.The team knew that the world is filled with mobile phones.About eighty percent of all people are said to live within reach ofa wireless telephone signal.
The idea was to use mobile phones and the Internet to connect job seekers with employers.The young people wrote a business plan and formed a company called Assured Labor.
Assured Labor won a development competition at the Massachusetts Institute of Technology
(MIT).Three of the founders were graduate students there.
Assured Labo ris an electronic market place.It has two parts.One is for;the Unied States.That operation was launched in January in Boston.It links pe'ople with employeis offering temporary jobs.
The other arm of the business is for developing markets.That operation is meant to help people get mbfe permanent jobs.A representative is currently building partnerships with universities,and international compaines in Central America.
Assured Labor’s presidenL David Reich,says the companies now place job advertisements on radio or in newspapers.Some even drive around in cars with loudspeakers announcing that jobs are available.He says the companies are interested.in having more modem hiring practices.
Through Assured Labpr,companies will list open positions on the Internet.People who think
they could do the job could reply by text messags or on their cellphones.
This is how the system works in Boston.
The jobs available include house cleaning.dog walking and home repai.People who want their house cleaned,for example,can look online at a list of twenty housekeepers.The list tells what services.they offer,and how much they want to be paid.People need two letters praising their work to get on the list of service providers.
The employer chooses workers they would like jto hire ,The company then sends the workers a text or e-mail message so they can respond quickly to an offer.
After a job is completed,the employer and employee rate each other, The rating is kept for future use.Assured Labor is not charging anyone,right now,but the plan is to have employers pay for the service.

上将该项涂黑。,
On an—airplane,a spacecraft or a man-made satellite,there is usually an installad device called the“biack box ”Made of a special kind of material.it would remain unbroken,even if the entire craft were blown to pieces.The box records some important data,which provide clues as to what changes had occurred before the real thing came along and help to discover the causes of the
disaster.
The black box.Therefore, becomes the last piece of evidence left.More often,it reveal a Schocking fact that many aircrafts met their disasters only beeanse of a simple but fatal mistake
Some hadn’t been supplied with sufficient fuel;others crashed due to a bird flying in their paths.In many cases。the pilot had been tired.In 1986,the famous US space siadttle Challenger exploded
soon after launch, because a screw on it was a bit loose!
An idea thus occurs to me:if a human being was equipped with a similar device,tracking all
the subtle inner Changes that had taken place over time,the results could astonish the world

Do you know about a series of books that say they are“for dummies”?These American self-help books have been translated into more than thirty-nine languages including Chinese,Arabic,Russian,French,German,Greek and Spanish.
“Dummy”is a word for a stupid person.The dummies books are not really for stupid people.
They are designed to show people how to do something they may never have tried before,like painting a house or learning a language.The books all say in a funny way that they are for dummies,such as World History for Dummies,Rabbits for Dummies,Chinese Cooking for Dummies,and Wedding Planning for Dummies.The first such book,DOS for Dummies,was published in 1991.It helped people learn how to use the DOS operating system for computers.Since then,more than one hundred fifty million dummies books have been sold.
The dummies.com website explains the idea behind the books.It says that they show that people can be taught to do anything.First they can make fun of ideas that are difficult to understand.Then they show how the information can be interesting and easy.The publishers(出版商)say that the books do not provide more information than necessary.They give readers just enough information to do what they want.They say that the dummies books give the best and easiest way to do something.And the books use simple and easy language.
There are more than one thousand different dnmmies books.A report in New York Times says that the top-selling dummies books are those that explain technology and personal finance(财经).
The publishers say that the best-selling dummies books are those providing information many people need—like information about diseases,education and cooking.People interested in opera,car repair and wine can also find dummies books to help them.And there are even more dummies books to come.The publishers say that they publish about two hundred new dummies books every year.

A mosquito is an insect that is found all over the world.There are thousands of different kinds of mosquitoes in many different sizes and colors.The female mosquito needs blood from vertebrates (animals that have a spine)to lay eggs and produce more mosquitoes.She has a special part of her mouth that she uses to suck blood,and her saliva(spit)thins the blood so she can drink it.In fact.it’s the mosquito’s saliva that makes the bites itch(痒)!
A person who gets bitten by a mosquito will notice a wheal,which is a bump around the bite.
The wheal will be round,with pink or red around the edge and white in the middle.The wheal will
itch a lot.Soon the wheal will disappear.but the itch will stay.
If you’ve been bitten by a mosquito,wash the bite with soap and water.Put on some calamine lotion to help stop the itching,or an adult can find an anti-itch cream at the drugstore for you.Placing an ice pack on the bite may also help.Tell all adult you’ve been bitten by a mosquito,especially if you live in the eastern United States.But if you develop an allergic reaction and feel dizzy or sick,tell a doctor immediately.He can treat allergic reactions with sole medicine.
The best way to avoid mosquito bites is to wear an insect repellent.Repellents that include one of these ingredients are best:BEET and lemon eucalyptus.Ask a parent to help you apply them.
Since mosquitoes lay their eggs in water,it’s also a good idea to empty out buckets,flower pots,toys and other things in your yard that may have collected water during a rainstorm.And when it’s possible,you’d better wear long-sleeved shirts and long pants to keep mosquitoes away from your skin.
