阅读下面一段文字，找出“碳链式反应”过程的三个关键性词语。

科学家在喀斯特地貌的研究中，发现了一个复杂的碳链式反应。当水流从空气中“大口吮吸”二氧化碳并侵蚀石灰岩时，持续不断的吸碳过程就开始了。接着，在岩石表面自由流淌的酸性水流携带着大量碳酸氢根，随着自然界的水循环转辗奔向江河湖海。此时，浮游植物体内的“食物加工厂”在急切地“找米下锅”，它们惊喜地发现，只要分泌一种叫做“碳酸酐酶”的催化剂，对水中的碳酸氢根“略施魔法”，等待加工的“米”——二氧化碳，就唾手可得。最终，光合作用将大量随波逐流的碳转化成有机碳，封存与水生植物体内。

阅读下面的短文，并根据短文后的要求答题（请注意问题后的词数要求。答案写在答卷纸上）

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.

I have been lucky to learn this lesson early because I have had a grass-cutting business since I was 10 years old. Of the money I make I spend about 10 percent and save the other 90.

Making sure you save and don't spend too much 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.

At high school many parents pay for almost everything, so your expenses can be small. If you have a job, 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. When you spend money, you not only lose that money, but also lose the interest you could have earned by saving it.

After high school, college is expensive and then "real" life begins, with expenses such as food and rent. If you can hold onto a good percentage of the money you earn as a teen, going to college and buying a house will be much easier. ________________, 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.

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.

Many say money cannot make you happy, and this is true. But money can help you to lead a secure life.

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 to this, it will mean you can live the way you want to without worrying.
