阅读下面短文并回答问题,然后将答案写到题后相应的位置上(请注意问题后面的词数要求).

[1] Learning to save money when you’re young is an important lesson. All good lessons and habits begin early, and saving is a skill that everyone needs. Many people-adults included-do not have a good sense of saving for the long run.

[2] Make sure you save and don’t spend too much, which is a good way to build up wealth. I have put my earnings in a bank. Many teens I know spend all the money they earn so it never has a chance to grow. Young people should realize that their teenage years are a great time to begin saving.

[3] At high school many parents pay for almost everything , so your expenses can be small, If you have a lot , you should have fun with some of the money. But you should also save some so that it will grow. Then you can begin planning for your future.

[4] After high school, college is expensive and then “real” life begins, with expenses such as food and rent. You can hold on to a good percentage of the money you earn as a teen. The earlier      ,the more time the money has to grow. If you are in your thirties without any savings, you will always have to struggle. The earlier you begin saving, the easier it is to create a nest egg.

[5]Later in life it can be hard to start saving because general costs of living are more expensive and you may only have enough to pay your bills. If you want to buy a house and have a family, you need money to start with, which comes from saving.

[6]Saving early will mean you will have to work for fewer years when you are older. It will also allow you to spend time doing the things that you want to do. In addition, it will mean you can live the way you want to without worrying.
