Competition. It’s a simple word, yet a very complex word that covers many angles when it comes to how gasoline prices are determined. It seems so easy to explain, but don’t let that trick you—it’s incredibly difficult to explain and adequately understand.

Say you’re on a Sunday afternoon drive, and notice a gas station near you charging $3.50. Down the road a few miles, that price could easily be 10 or more cents higher or lower. The question is “how” or “why” is that? Think of it this way. Are you more likely to get a better deal on a car if there are two similar car dealers next to each other? Perhaps, because the dealers are too close. Say there is a third similar car dealer miles away. Is he going to be at the same level of competition and sell his cars for the same price as the two dealers next to each other? Likely not. He may charge more or less. Maybe people don't know there are two other dealers down the road. Maybe the dealer is almost outside of the city and the land value isn't as high, so his taxes aren't as high.

These situations do take place at gas stations. And more factors can impact what a station will charge. Timing can greatly impact what price a station charges as well! Many motorists fail to realize that the price a station pays for gasoline changes daily. If one station gets lucky and buys gas on Monday and the cost goes up Tuesday, the station that bought on Monday doesn’t necessarily have to raise prices like the station that bought on Tuesday. Maybe the station that got caught buying for a higher price on Tuesday will pass that higher cost on by raising its gas price.

Perhaps the difference is what brand the station is---branded stations usually pay a slightly higher cost for their gasoline. In return for paying a higher cost, those stations are guaranteed first supply in case of emergency situations. Independent stations don’t pay as much, but aren’t guaranteed supply.

While competition sounds easy to understand, there are always a large number of factors that could influence what one station charges. Keep in mind how many variables there are next time you fill up.

Today’s drivers may feel shocked by the high price of petrol when they drive to the gas station. However, the car industry has the technology to solve the problem. It’s the hybrid car（混合动力汽车）.

What is a hybrid car? Any car that uses two or more sources of power is a hybrid car. Most hybrid cars on the road right now are petrol-electric hybrids. The petrol-electric hybrid car is just what it sounds like — a cross between a petrol-powered car and an electric car.

A gas-powered car has a fuel tank（油箱）, which supplies petrol to the engine. An electric car, on the other hand, has a set of batteries that provides electricity for the car.

To be useful to you or me, a car should be able to run at least 300 miles (483 km) before refueling, be capable of(能够) being refueled quickly and easily and fast enough to keep up with the other traffic on the road.

A petrol car meets these requirements（要求）but produces a large amount of pollution. An electric car, however, produces almost no pollution, but can only go 50 to 100 miles (80 to 161 km) between recharging(充电). And the problem has been that the electric car is very slow and inconvenient to recharge.

A petrol-electric car combines the advantages of the two power sources into one system that uses both gas power and electric power. Some experts believe that the hybrid car is “the next generation of smart cars”. A hybrid car can go up to 50% further than a traditional car can on the same amount of gas! It saves driver’s money on gas and cuts air pollution!

1.What do the underlined words “the problem” in Paragraph 1 refer to?

A．The price of petrol goes up and down.

B．The gas-powered car is sold at a high price.

C．The gas-powered car causes air pollution.

D．The price of petrol keeps going up.

2.How many sources of power do most hybrid cars use?

A．Two.

B．Three.

C．Four.

D．It depends.

3.The author thinks that electric cars _____.

A．are smart vehicles

B．are popular vehicle

C．are not practical

D．are not slow

4.Some experts believe that the hybrid car will have a large market in future because _____.

A．it is just powered by renewable energy

B．it saves money and is eco-friendly

C．it goes further than a traditional car

D．it is safe, cheap and produces no air pollution
