Advertisement can be thought of "as the means of making known in order to buy or sell goods or services". Advertisement aims to increase people's awareness and arouse interest. It tries to inform. and to persuade. The media are all used to spread the message. The press offers a fairly cheap method, and magazines are used to reach special sections of the market. The cinema and commercial radio are useful for local market. Television, although more expensive, can be very effective. Public notices are fairly cheap and more permanent in their power of attraction. Other ways of increasing consumer interest are through exhibitions and trade fairs as well as direct mail advertisement.
There can be no doubt that the growth in advertisement is one of the most striking features of the western world in this century. Many businesses such as those handling frozen foods, liquor, tobacco and medicines have been built up largely by advertisement.
We might ask whether the cost of advertisement is paid for by the producer or by the customer. (19) Since advertisement forms part of the cost of production, which has to be covered by the selling price, it is clear that it is the customer who pays for advertisement. However, if large scale advertisement leads to increased demand, production costs are reduced, and the customer pays less.
It is difficult to measure exactly the influence of advertisement on sales. When the market is growing, advertisement helps to increase demand. When the market is shrinking, advertisement may prevent a bigger fall in sales than would occur without its support. What is clear is that businesses would not pay large sums for advertisement if they were not convinced of its value to them.
Advertisement is often used to______.
A.deceive customers
B.increase production
C.arouse suspicion
D.push the sale

The train clattered over points and passed through a station. Then it began suddenly to slow down, presumably in obedience to a signal. For some minutes it crawled along, then stopped, presently it began to move forward again. At that moment another train, also on a down line, swerved inwards towards them, for a moment with almost alarming effect. For a time the two trains ran parallel, now one gaining a little, now the other. Mrs. McGillicuddy looked from her window through the windows of the parallel carriages. Most of the blinds were down, but occasionally the occupants of the carriages were visible. The other train was not very full and there were many empty carriages. At the moment when the two trains gave the illusion of being stationary, a blind in one of the carriages flew up with a snap. Mrs. McGillicuddy looked into the lighted first-class carriage that was only a few feet away.
Then she drew her breath in with a gasp and half-rose to her feet.
Standing with his back to the window and to her was a man. His hands were round the throat of a woman who faced him, and he was slowly, remorselessly, strangling her. Her eyes were staring from their sockets, her face was purple. As Mrs. McGillicuddy watched, fascinated, the end came; the body went limp and crumpled in the man's hands.
At the same moment, Mrs. McGillicuddy's train slowed down again and the other began to gain speed. It passed forward and a moment or two later it had vanished from sight.
Almost automatically Mrs. McGillicuddy's hand went up to the communication cord then paused, irresolute. After all, what use would it be ringing the cord of the train in which she was traveling? The horror of what she had seen at such close quarters, and the unusual circumstances, made her feel paralysed. Some immediate action was necessary--but what?
The door of her compartment was drawn back and a ticket collector said, "Ticket, please."
When Mrs. McGillicuddy's train passed through a station, it ______.
A.gained speed suddenly
B.kept its usual speed
C.changed its speed
D.stopped immediately
