To be able to motivate oneself, or self-motivate, occurs when a person has the willingness to do something and is internally(内在地) motivated to do it．
Sometimes it’s very difficult to get ourselves moving．The natural tendency is to postpone．Life just seems to get in the way! There is a job to go to, groceries to do, television to watch—whoops! I guess we get pretty good at finding excuses to escape getting started on goals like an exercise routine or reading a new book．The fact is that we are creatures of routine and habit．So what can we do to motivate ourselves to accomplish our goals? 
Here are some tips on how to get moving:
Decide what you want．It’s hard to motivate an aimless mind．Set a goal and decide how you are going to go about it．Then break it down into smaller sections so it’s easier to handle and less overwhelming．（势不可挡）
Keep track of your progress．Keep a log or journal where you can measure how much you have accomplished．Looking at it can also motivate you to keep pushing ahead．
Post motivating pictures or slogans within your sight．It is always inspiring to see pictures of people who have accomplished what you’re going for．It makes it attainable and realistic．Likewise, little slogans like “go for it” or “just do it” can give you the little support you need．    
Sometimes we forget what we set out to do and a little reminder is all we need to be revitalized (激活) and focus on the end result．If you remind yourself to go for the desired promotion, it will re-establish why you are doing what you’re doing．
Make it a habit．Once you have accomplished your objective, e．g．becoming an early riser, keep it up so that it’s second nature to you and you don’t have to think about it anymore．

For years scientist have been worried about the effects of air pollution on the earth’s natural conditions. Some believe the air inside many houses may be more    41    than the air outside. It may be one hundred times worse.
Indoor air pollution can cause a person to feel tired, to    42     eye-pain, headache and other problems. Some pollutants can cause breathing disorders, diseases of blood and even cancer. Most scientists    43    that every modern house has some kind of indoor pollution. People began to    44    the problem in the early 1970s, when it was that builders began making houses and offices which did not waste energy. To do this they built buildings that    45    the flow of air between inside and outside. They also began using man-made building materials. These materials are now known to    46    harmful gases. As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control    47    for building green plants. Scientist do not really know how plants control air pollution. They believe that a plant’s leaves take in the pollutants. In exchange the plant produces oxygen    48    its leaves and through its tiny organizations on its roots. Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square meters of space. Studies of different plants show that each    49    different chemicals. So the most effective way to clean the air is to use different kinds of plants. Having green plants inside your house can make it a prettier and healthier place.
