[不定项选择题]共用题干 第三篇

In one sense,an allowance is a child's share of the family income.It can be a good experience that parents can provide for their children.The amount should be what the family can afford.It should be given to the youngsters to do with as they please,but not be used as a tool to win the youngsters' good behaviors.
An allowance is not a bribe.It should be thought of as a learning tool,giving the youngsters firsthand experience in learning how to spend money. It can teach them how to get the best value for what they buy,helping them use their skills in arithmetic.
Many youngsters make mistakes and buy unwisely at first. Some rush out to spend all their money the moment they get it.They forget that once it is spent,there will be no more for several days.From such haste,youngsters can learn how to choose wisely and spend carefully.
Parents need to know when to begin to give an allowance and how much to give.When a youngster starts school,he/she may want it,because his/her friends receive one.A good time for considering it may be when a youngster makes daily requests for ice cream or candy.This will help him/her to see the value of money.
At first a youngster may receive only half an allowance but get it twice a week.This would help someone find a full week too long. She will soon figure out that she can have two candy bars this week,or save for two weeks to buy a toy,learning that she cannot have them both.
A wise parent won't control the child's buying. By making her own mistakes with her own money,the child is more apt to learn from her mistakes.An allowance should not be taken away as punishment for bad behavior,nor as pay for doing household chores（杂务）.
A youngster should be encouraged to be generous,helping her see that money isn't everything. No amount of money can buy friendship.Things such as love and respect do not have a price tag. The amount of an allowance should depend upon_________.
A.what the family can afford
B.what the family can borrow
C.how the parents like
D.how much the family can save
