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．From the basic concrete ideas to the more abstract problems, he is master in making math lectures learner-friendlier and less scary．

　　With a PhD in Mathematics Education from Georgia State University, Dr．Siegel teaches mathematics at Central Arizona College．His courses include various make-up classes and a number of lectures for future primary school teachers．

　　If the course fails to provide complete satisfaction to you, you can easily exchange it for any other course that we offer．Or you can get your money back．

I needed to buy a digital camera, one that was simply good at taking good snaps (快照), maybe occasionally for magazines. Being the cautious type, I fancied a reliable brand. So I went on the net, spent 15 minutes reading product reviews on good websites, wrote down the names of three top recommendations and headed for my nearest big friendly camera store. There in the cupboard was one of the cameras on my list. And it was on special offer. Oh joy. I pointed at it and asked an assistant, “Can I have one of those?” He looked perturbed (不安).“Do you want to try it first?" he said. It didn't quite sound like a question. "Do I need to?" I replied. "There's nothing wrong with it?" This made him look a bit insulted and I started to feel bad. "No, no. But you should try it," he said encouragingly." Compare it with the others. "

     I looked across at the others: shelves of similar cameras placed along the wall, offering a wide range of slightly different prices and discounts, with each company selling a range of models based around the same basic box. With so many models to choose from, it seemed that I would have to spend hours weighing X against Y, always trying to take Z and possibly H into account at the same time. But when I had finished, I would still have only the same two certainties that I had entered the store with: first, soon after I carried my new camera out of the shop, it would be worth half what I paid for it; and second, my wonderful camera would very quickly be replaced by a new model.

     But something in the human soul whispers that you can beat these traps by making the right choice, the clever choice, the wise choice. In the end, I agreed to try the model I had chosen. The assistant seemed a sincere man. So I let him take out my chosen camera from the cupboard, show how it took excellent pictures of my fellow shoppers... and when he started to introduce the special features, I interrupted to ask whether I needed to buy a carry-case and a memory card as well.

      Why do we think that new options (选择) still offer us anything new? Perhaps it is because they offer an opportunity to avoid facing the fact that our real choices in this culture are far more limited than we would like to imagine.

1. The shop assistant insisted that the writer should __ .

     A. try the camera to see if there was anything wrong with it

     B. compare the camera he had chosen with the others

     C. get more information about different companies

     D. trust him and stop asking questions

2. What does the writer mean by "it would be worth half what I paid for it"  (Paragraph 2) ?

     A. He should get a 50% discount.

     B. The price of the camera was unreasonably high.

     C. The quality of the camera was not good.

     D. The camera would soon fall in value.

3. The writer decided to try the model he had chosen because he __ .

     A. knew very little about it

     B. didn't trust the shop assistant

     C. wanted to make sure the one he chose would be the best

     D. had a special interest in taking pictures of his fellow shoppers

4. It can be inferred from the passage that in the writer's opinion, __

     A. people waste too much money on cameras

     B. cameras have become an important part of our daily life

     C. we don't actually need so many choices when buying a product

     D. famous companies care more about profit than quality

China_is_going_green. In order to reduce air pollution and oil­shortages, automobile manufacturers have announced their plans to develop hybrid vehicles (混合燃料汽车) for the Chinese market. Toyota's hybrid car Prius will be ready to drive in China this week. Let's have a look at the new car.

Any vehicle is a hybrid when it combines two or more sources of power. Hybrid cars run off a rechargeable battery and gasoline. Hybrid cars have special engines, which are smaller than traditional gasoline engines. They run at 99 percent of their power when the car is cruising (匀速行驶). A specially designed battery motor provides extra power for running up hills or when extra acceleration is needed.

Step into a Prius, and turn on the engine. The first thing you notice is how much quieter it is than a traditional car. At this point, the car's gasoline engine is dormant (休眠). The electric motor will provide power until the car reaches about 24 km/h. If you stay at a low speed, you are effectively driving an electric car, with no gasoline being used, and no waste gas gives off.

The onboard(车载的) computer makes the decision about when to use a gas engine, when to go electric, and when to use a combination of the two. If you go over 24 km/h, when you step on the gas pedal (油门), you are actually telling the computer how fast you want to go.

The electronic motor recharges automatically using a set of batteries. When driving at high speed, the gasoline engine not only powers the car, but also charges the batteries. Any time you use the brake, the electric motor in the wheels will work like a generator and produce electricity to recharge the batteries. As a consequence, the car's batteries will last for around 200,000 miles.

1.The author writes this passage mainly to________.

A．teach people how to drive a hybrid car

B．introduce a new kind of “green” car

C．show how to save their gasoline when driving a car

D．announce plans to develop hybrid vehicles for China

2.The first sentence probably refers to ________.

A．there will be more and more green land in China

B．China is still young and lacking experience

C．China's new cars are combinations of different green models

D．China has started producing environmentally friendly cars

3.Which of the followings is NOT true?

A．The hybrid cars reduce air pollution and oil­shortages.

B．The car's gasoline engine doesn't work until it reaches about 24 km/h.

C．This kind of car is completely controlled by an onboard computer.

D．A specially designed battery motor provides extra power when needed.

4.What is the most important feature of hybrid cars?

A．They are powered by both a rechargeable battery and gasoline.

B．They are much quieter than traditional cars.

C．They only use 99 percent of their power to run up hills.

D．They have smaller engines than traditional gasoline ones.
