The goal of earthquake prediction is to give early enough warning. The U.S. Geological Survey conducts and supports research on the likelihood of future earthquakes. Scientists estimate earthquake probabilities in two ways: by studying the history of large earthquakes in a special area and the rate at which strain（拉力）accumulates（积累）in the rock.
Scientists study the past frequency of large earthquakes in order to determine the future likelihood of similar large shocks. For example scientists researched the large earthquakes in the San Francisco Bay region during the 75 years between 1836 and 1911. For the next 68 years, no earthquakes of magnitude (震级) 6 or large occurred in the region. Beginning with a magnitude 6 shock in 1979, the earthquakes in the region increased dramatically; between 1979 and 1989, there were four magnitude 6 or greater earthquakes, including a magnitude 7.1 earthquake. So scientists estimated that the probability of a magnitude 6.8 or larger earthquake occurring during the next 30 years in the region is about 67 percent.
Another way to predict earthquakes is to study how fast strain accumulates. When plate movements build the strain in rocks to a critical level, like pulling a rubber band too tight, the rocks will suddenly break and slip to a new position. Scientists measure how much strain accumulates along a fault (断层) each year, how much time has passed since the last earthquake, and how much strain was released in the last earthquake. This information is used to calculate the time required for the accumulating strain to build to the level that results in an earthquake. This simple model is so complicated that such detailed information about faults is rare. In the United States, only the San Andreas Fault System has adequate records for using this prediction method.
Scientific understanding of earthquakes is of vital importance to the Nation. As the population increases, expanding urban development and construction encroach (侵蚀) upon areas susceptible(易受影响的) to earthquakes. With a greater understanding of the causes and effects of earthquakes, we may be able to reduce damage and loss of life from this destruction.

Probably the hardest part of setting goals is the first step of actually deciding to take action! The first barrier that most people face is the incorrect assumption(假设) that goals are only for business people. The reality is that everyone sets goals mentally throughout the day. There are always occasions where something has to be done at a particular time or in a particular place. Simple examples could be getting up at a certain time in order to be at work, or to meet with a friend for an activity.
The beauty of having goals is the uniqueness of each one to the goal setter. Whether it is personal, financial, or business, they are all specific to that person and their situation.
The most important part is to write them down. Having goals written down gives you power while helping you to focus on this area.
Aim for something that will stretch you while remaining achievable. If you achieve your goal too easily, it is not high enough to make any significant change in your life. On the other hand, if you consistently miss the goals, consider setting them a little lower as you will only get discouraged and probably give up. The aim is to keep you growing and moving into a more satisfactory position.
As you reach the levels that you have set for yourself, always include a small reward at each point. This might only be a small thing in the early days like a meal out or a weekend vacation.
Remember that these changes will not happen overnight and there will be a period of time when nothing seems to be happening. This is why the goals need to be detailed and as specific as possible with a result and benefit.
Allow some time on a daily basis to educate yourself on how to make the necessary adjustments in your life. This could include listening to a CD, or reading a book, etc.
A simple method to start with could be one goal in the main areas of life to be achieved in one month, six months, twelve months or five years. Break that down further into a daily, weekly and monthly system. Stay focused and stick to achieving all that you desire.
1.The main examples in Paragraph 1 tell us that ________.
A. goals are set mostly for important things
B. most people know when it is time to set goals
C. people can set goals to get things done all the time
D. it is necessary to get goals once in a while
2.The charm of having goals is that each goal is ________.
A. important B. achievable C. special D. meaningful
3.A good goal is one that is ________.
A. easy enough for you to feel nice B. high enough yet achievable
C. always in a satisfactory position D. changed again and again

阅读下面的短文，然后按照要求写一篇150词左右的英语短文。
The ultimate （最终的） goal of life is to achieve happiness, and the way to achieve happiness is to wise management. So says The Sims (模拟人生)，an American strategic life-simulation computer game that lets you create, direct, and manage the lives of SimCity’s residents.
Similar to the life of a real person, the game begins with the creation of your simulated（模拟的）people: pick a name and a gender, decide on personality/astrological sign (星座), and then choose a look from a variety of heads, bodies, and skin tones. Each little Sim person has all basic needs (Hunger, Comfort, Fun, etc.) like a human which can be satisfied by interaction with other Sims or purchased objects. Name, gender, and appearance don’t affect gameplay much, but personality determines how your Sim plays with others.
One gameplay goal is to improve your Sim and eventually help him or her achieve happiness. With proper management he or she can climb a career ladder, which nets him or her more money. This allows the purchase of higher quality stuff, which lets you improve your Sim even more. With suitable care, your Sim can have a mate, kids, and a mansion with an indoor pool. Mismanage your new, simulated family, and fights will break out, jobs will be lost, and the house will fall apart.
With The Sims, you can create whatever and whomever you desire. Triumph or tragedy? You name it. In your real life, it is the same case.
