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.
