The first automobile was invented more than two hundred years ago. It used steam for power and had wooden wheels. The first automobile may have been simple and primitive, but it was an extremely important invention. The automobile today is the primary means of land transportation. It has produced more changes in our daily life than any other machines.
Almost all gasoline engines work in the same way—with four movements, or strokes, of a piston in a cylinder. The first stroke pulls the fuel mixture (gasoline and air) into the cylinder. The second stroke compresses the fuel mixture. A spark plug produces a spark that ignites the fuel mixture and causes the third stroke. The final stroke removes any waste gases which might remain in the cylinder.
The preceding paragraph explains what happens inside the cylinder to make the piston move. When the piston is pushed down by the explosion in the third stroke, it pushes the connecting rod. This rod rotates the crankshaft. The crankshaft is connected to other parts which turn the wheels. Most cars today have four, six, or eight cylinders.

Our sense of smell, which we normally take for granted, is nowadays being increasingly used for purposes which might surprise us if we aware of them. One area in which smells are created to achieve particular results is marketing. For some time manufacturers have taken advantage of our sense of smell with regard to household goods. Millions of dollars are spent on product research in the hunt for the right smell as it is believed perfume influnences the way consumers perceive a brand. In a survey in the United States, when people were asked what was the most important factor in their choice of detergent (洗衣粉) , smell was rated highly, above ingredients and price.
Now stores are becoming even more direct in their use of smell. The smell of fresh bread in a supermarket tends to encourage people to buy, and people selling their houses are recommended to have coffee being heated when potential buyers arrive. Suddenly smell is becoming big business. One company specializing in the use of smells to attract customers now has many large stores on its own list of customers. They find that when pleasant smells are filtered through a store’s air condition system, people tend to spend longer in the store and buy more.
Reserch shows that smells can increase people’s view of the value of a product. In a test, people looked at the same types of shoes in two rooms--one filled with purified air, the other with a smell of mixed flowers, of the people preferred the shoes in the room with the smell of flowers. In fact, many said they would be prepared to pay up to US$10 more for a pair.
Smells also have other potential uses. Some companies are experimenting with different smells to produce different effects in their workers according to the time of day. For example, early in the morning they might put the smell of lemon in the air conditioning system to wake people up. In the middle of the morning, when the atmosphere tends to become more tense, the smell of wood could be used to calm people down. Before lunchtime the smell of melting butter would encourage people to go to lunch on time . After lunch, when people often begin to lose concentration, the smell of mint (薄荷) would increase their alertness.
In the survey, when selecting detergent, people considered smell ______.

A:not important B:as important as price C:less important than ingredients D:more important than price
