  小题1:  . Not caring about the money, parents in China often send their children to the best schools or even abroad like England, the US or Australia. They also want their children to take extra-course activities where they will either learn a musical instrument or ballet, or other classes that will give them a head start in life. The Chinese believe that the more expensive an education is, the better it is. So parents will spend an unreasonable amount of money on education.    小题2:  .

Parents can see that their children’s skills vary, skilled in some areas while poor in others.    小题3:  . Teaching a child to cook will improve many of the skills that he will need later in life. Cooking demands patience and time.    小题4:  . A good cook always tries to improve his cooking, so he will learn to work hard and gradually finish his job successfully. His result, a well-cooked dinner, will give him much satisfaction and a lot of self-confidence.
