But you need to be quick. And you need to understand a few basic rules about the wind. First, you must ask

21、yourself, “Where is the wind coming from? Is it coming 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. Lets start with the wind blowing from the behind. This means the wind and the boat are going in th

22、e 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.

23、 45 angle to the boat. It needs to be out far enough to catch the wind, but it shouldnt flap (摆动). It shouldnt 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

When you are tacking, you must always keep the sail inside the boat. 45. What should you consider first while sailing? A. Sa

27、ture (文化) the smile is in general an expression of pleasure. Yet it also has other uses. A womans smile at a police officer does not carry the same meaning as the smile she gives to a young child.

For example, many people in Russia smiling at strangers in public to be unusual and even improper. Yet many Americans smile freely at strangers in
