第四部分：阅读理解（共20小题，每题2分，满分40分）

There are three kinds of goals: short-term, medium-range and long-term goals.

Short-range goals are those that usually deal with current activities, which we can apply on a daily basis. Such goals can be achieved in a week or less or two weeks, or possible months. It should be remembered that just as a building is no stronger than its foundation, out long-term goals cannot amount to very munch without the achievement of solid short-term goals. Upon completing our short-term goals, we should date the occasion and then add new short-term goals that will build on those that have been completed.

The intermediate goals are built on the foundation of the short-range goals. They might deal with just one term of school or the entire school year, or they could even extend for several years. Any time you move a step at a time, you should never allow yourself to become discouraged or overwhelmed. As you complete each step, you will enforce the belief in your ability to grow and succeed. And as your list of completion dates grow, your motivation and desire will increase.

Long-range goals may be related to our dreams of the future. They might cover five years or more. Life is not a static thing. We should never allow a long-term goal to limit us or our course of action.
