    Most children don't enjoy doing housework. They like playing computer games rather than cleaning the

rooms. But in Australia, Jim and Robert's mother, Mrs Black, has good and proper methods to get their

children to do housework.

    Here is an example.

    "Mum, have you worked out next week's housework? Let Jim and me choose the cards. I can't wait.

It's fun!"

    When Robert shouted out, his mother had already put all the cards on their big table. On the cards, there

are some words like these, "sweep the floor, clean your bedroom, help mum cook, wash vegetables, make

beds, feed the fish, cut the wood, clean the bathroom" and many others. Jim and Robert chose two cards

for each day from Monday to Friday. Then they would hang them on the weekday task board. Jim likes to

clean the bathrooms, so he picked up the card "clean the bathroom", Robert loves to make the bed. so he

picked up his favorite card. Jim again picked up "wash vegetables" and Robert chose "feed the fish". Soon

the two boys were happy to take away all the cards.

    To help the children do housework, their mother thought hard and came up with this idea. Of course, the

parents did the housework on the weekends and left Jim and Robert two days free.
