You may think that sailing is a difficult sport, but it is really not hard to learn it. You do not need to be strong. But you need to be quick. And you need to understand a few basic rules about the wind.
First, you must ask yourself, “Where is the wind ing from? Is it ing from ahead or behind or from the side?” You must think about this all the time on the boat. The wind direction tells you what to do with the sail.
Let’s start with the wind blowing from the behind. This means the wind and the boat are going in the same direction. Then you must always keep the sail outside the boat. It should be at a 90° angle (角度) to the boat. Then it will catch the wind best.
If the wind is blowing from the side, it is blowing across the boat. In this case, you must keep the sail half way outside the boat. It should be at a 45° angle to the boat. It needs to be out far enough to catch the wind, but it shouldn’t flap (摆动). It shouldn’t look like on a flagpole. If it is flapping, it is probably out too far, and the boat will slow down.
Sailing into the wind is not possible. If you try, the sail will flap and the boat will stop. You may want to go in that direction. It is possible, but you can’t go in a straight line. You must go first in one direction and then in another. This is called tacking. When you are tacking, you must always keep the sail inside the boat.

解析：【文章大意】
本文是一篇说明文。文章介绍了帆船运动的一些常识，进行帆船运动必须掌握风向，风向决定着帆船的运动速度。后文分别就顺风行驶、侧风行驶和逆风行驶进行了阐述。
【小题1】根据第二段中的“First, you must ask yourself, “Where is the wind ing from? Is it ing from ahead or behind or from the side?””可知风向是决定帆船最重要因素。
【考点定位】考查细节理解。
【小题2】根据文章中的“you must keep the sail half way outside the boat. It should be at a 45° angle to the boat. It needs to be out far enough to catch the wind, but it shouldn’t flap (摆动).”可知it指代the sail。
【考点定位】考查猜测词义。
【小题3】根据文章最后一段中的“It is possible, but you can’t go in a straight line. You must go first in one direction and then in another. This is called tacking.”所以选D。tack the boat意为：改变船航向。
【考点定位】考查判断推理。
【小题4】帆船运动是普通的一种体育运动，因此，本文很可能从流行杂志中节选。
【考点定位】考查推理判断。
