     Are you unhappy about the shape of your nose? Or do you feel that your ears are too big

or your eyes too small? Yon don't need to despair (绝望) about any of these things any longer.

They can all be put right by a surgeon. Surgeons are doctors who make sick people well by

operating on them. But some surgeons today are really beauty specialists (专家). Their job is

to make ugly or plain people beautiful. This work is called plastic surgery (整形外科). Plastic

surgeons are very popular in some countries. They make a lot of money by selling beauty to men

and women, especially women. Plastic surgery is very expensive. A new nose may cost almost

as much as a new car. Suppose I can afford to pay so much money and want to change my ugly

nose for a more handsome one. I first consult (咨询) a plastic surgeon. First of all, he will ask me

to enter a nursing home. I shall have to spend about three weeks there. The surgeon will give me

an aesthetic (麻醉剂). Then he will operate on my nose to give it the shape I want. He will put a

plaster case over it to keep it in its new shape. I shall have to spend the next week or two anxiously

wondering whether the operation has been successful or not. "Will my nose really look better?" Or

will I look uglier than before? Won't there be scars (疤痕) after the operation? What shall I do if my

 nose is not the shape I wanted? And then the great day will come. The surgeon will take off the

bandages and the plaster, and I shall see my expensive new nose! Will it be worth all the trouble

and expense? Sometimes these operations go wrong, and then the patient comes away looking

worse than before.
