问题 实验题

为了确定方向,可以把手臂浸入水中,然后向上举起,手臂的哪一面感到凉,风就是从哪一面吹来的。用学过的物理知识对上述现象进行简单解释。

答案

有风的一面蒸发加快,所以感到凉;

①手臂的哪一边凉,说明那一边蒸发快,吸热多.有风的那边空气流动快,蒸发快.

②生活中蒸发吸热的例子很多,比如:喝开水时,向杯子上方吹气,可使开水凉得快一些.雨后天晴,地上变干;湿衣服晒干;从游泳池的水中上来的人为什么感觉比在水中冷等等.

写作题

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.
