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.

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.
【小题1】What does the course Basic Math mainly cover?

Speaking of Copenhagen, what do you think of? The little Mermaid, the fairy tale writer H.C. Anderson, the COP15 meetings , or a city where people bike even though they have cars.
When landing on Copenhagen Tasstrup Airport, you can see numbers of white propeller generators standing in the blue waterfront. The constant moving paddles are producing renewable energy to the city. During the recent Climate Change Conference, the city was introduced to the world as an example of climate-friendly city. Evidences other than wind power stations were obvious everywhere.
While private cars can be a great source of pollution in other cities, the main form of transport in the capital of Denmark is, however, public transportation. By public transportation, I mean one of very good quality. Buses are usually Volvo and most of the traffic lights are of Siemens. Additionally, buses, metros and intercity-trains (named S-train) are well equipped, constantly maintained, special and good-looking. The seats in the trains are of sofa-designed. Sticky gum or dirty spot rarely appear. Thanks to a small population, it is much easier to maintain the condition of the vehicles. Free wireless internet service is provided in S-trains. Seats are always possible even at rush hours if the passenger is patient enough to look for it. Taking the convenience for granted, Danish people find it hard to imagine how the metro in Tokyo can be as crowded as a “sardin can”. Pets and baby-wagons are allowed in buses, subways and S-trains. All the facilities enable better service to bigger passenger group. It is also notable that the mass transit uses green fuels and electricity.
Cars are common in Copenhagen, but people have an alternative of short distance transport: bikes. Denmark is known as bike-friendly for many reasons, such as flat land, splendid cycle ways, and the Danish fond of motion. But please be aware that riding a bike in Copenhagen is not like biking in Beijing. First of all, it is quite speedy. Many people ride to work every morning. Punctuality is important and they have to ride as fast as possible to be on time. So why not speed up? Not my philosophy. As a result, I am often hastened by impatient riders who unfortunately piled up after me. Second, considering the speed, bike helmets, front and back lights and other necessary accessories are required. Riders need to set a white light in the front of the bike and red light at the back. One may end up with a big fine if not riding with them.
72. In the passage we get to know that _____.
all energy come from wind power stations
different kinds of green energy keep this city running
a lot of electricity is imported from other countries
people in this city use little energy
73. S-trains are a kind of transportation______.
A. which send their passengers from one city to another.
B. which uses wind to run their ways
C. which is the only way for you to go from one city to another.
D. which you are not allowed to take if you take a pet.
74. In the last paragraph what does “Punctuality” mean?
A. Being fit         B. Not being scolded       C. Not being late      D. Speeding
75. In Copenhagen if you ride too slow ,_____
A. you will be fined by police.
B. it means that you need to buy a better bike.
C. you may block the traffic flow.
D. many bike riders will shout at you.

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 is 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 of my chosen camera from 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 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.

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

B. compare the camera he had chosen with the others.

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
