Every human being has a unique(唯一的，独特的)arrangement of the skin on his fingers and this arrangement is unchangeable. Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children, though nobody knows why this is the case.

The ridge structure on a person’s fingers does not change with growth and is not affected by surface injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new one, which bears a reproduction of the original pattern. It is only when the inner skin is injured that the arrangement will be destroyed. Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take.

Finger-prints can be made very easily with printer’s ink. They can be recorded easily. With special methods, identification(辩认，鉴定)can be achieved successfully within a short time. Because of the simplicity and economy of this system, finger-prints have often been used as a method of solving criminal case. A suspected man may deny a charge but this may be in vain. His finger-prints can prove who he is even if his appearance has been changed by age or accident.

When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect with the naked eye. Special techniques are used to “develop” them. Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained.

Make Up Your Mind to Succeed

Kind-hearted parents have unknowingly left their children defenseless against failure．The generation (age) born between 1980 and 2001 grew up playing sports where scores (marks) and performance (show) were played down because “everyone's winner.” And their report cards sounded more positive than ever before．As a result, Stanford University professor Carol Dweck, PhD, calls them “the overpraised generation.”

Dweck has been studying how people deal with failure for 40 years．Her research has led her to find out two clearly different mind-sets that have a great effect on how we react to it．Here's how they work:

　　A fixed mind-set is grounded in the belief that talent is genetic – you're a born artist, point guard, or numbers person．The fixed mind-set believes it's sure to succeed without much effort and regards failure as personal shame．When things get difficult, it's quick to blame (liability), lie, and even stay away from future difficulties.

　 On the other hand, a growth mind-set believes that no talent is entirely heaven-sent and that effort and learning make everything possible．Because the ego (自尊) isn't on the line as much, the growth mind-set sees failure as a chance rather than shame．When faced with a difficulty, it's quick to rethink, change and try again．In fact, it enjoys this experience.

　　We are all born with growth mind-sets．(Otherwise, we wouldn't be able to live in the world.) But parents, teachers, and instructors often push us into fixed mind-sets by encouraging certain actions and misdirecting praise．Dweck's book, Mind-set: The New Psychology of Success, and online instructional program explain this in depth．But she says there are many little things you can start doing today to make sure that your children, grandchildren and even you are never defeated by failure.

A．doesn't want to work hard

B．cares a lot about personal safety

3.What does the growth mind-set believe?
