阅读下面短文,根据所读内容在表格中的空白处填入恰当的单词。

注意:每个空格只填一个单词。

     The Chinese are very generous when it comes to educating their children.Some parents

send their children to the best schools or even abroad to England,the US or Australia,regardless

of how much this costs.Many also want their children to take extra curriculum activities where

they 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

often spend unreasonable amount of money on education.Even poor couples buy a computer

for their son or daughter.

However,what most parents fail to see is that the best education they can give their children is

usually very cheap.Parents can see that their children's skills vary;they will usually be skilled in

some areas while poor in others.What most parents fail to realize though,is that today's children

lack self respect and selfconfidence.

     The problem is that parents are only educating their children on how to take multiple choice

tests and how to study effectively.They are not teaching them the most important skills they need

to be confident,happy and clever.

     Parents can help achieve this by teaching their children practical skills like cooking,sewing and

other housework.

     Teaching a child to cook will improve many of the skills that he will need later in life.Cooking

demands patience and time.It is an enjoyable but difficult experience.A good cook always tries

to improve his cooking,so he will learn to work hard and gradually finish his job successfully.The

result,a well cooked dinner,will give a child a lot of satisfaction and confidence.

     An old machine such as a broken radio or TV set that you give your child as a toy may make

him curious and arouse his interest.If he will spend hours looking at it,and try to mend it;your child

might become an engineer when he grows up.Such activities do more than teach a child to read a

book;but rather they teach them to think,and to use their minds.This is much more important than

learning by reading a book.
