Rules to play Paddleball
Use of Paddle and Ball
A player may not carry a second paddle or a second ball during play, although it is permissible to use both hands on the paddle and to switch the paddle from hand to hand in the course of play.
With regard to ball change, play should continue with the same ball as long as it is in good condition. In tournament matches;
Play should continue with the same ball throughout a set, and the ball should not be changed during the set unless.
The ball becomes clearly defective, such as a crack or split in the ball, or.
If, for any other reason, all four players agree that the ball should be changed during the set. Unless all four agree to the change to a new ball, play should continue with the same ball through the completion of the set.
At the end of a set, play can continue with the same ball; however, if any one player desires a new ball, the ball change is made.
Both yet and already are used with the present perfect tense. Already is usually used in positive sentences. Yet is usually used in questions and negative sentences.
Imagine that you and your friend are going to travel. There are many things to do, and you ask your friend if he has done these things: Have you bought the tickets yet? Have you arranged a taxi yet? Have you reserved the hotel room yet? Have you packed the bags yet?
In all the examples, use yet at the end of the question. Your friend might answer: Yes, I've already bought the tickets. Yes, I've already arranged a taxi. No, I haven't reserved the room yet. No, I haven't packed the bags yet.
Use already in the positive answers, and yet in the negative answers.
There is one time you can use already in questions: it's when something happens earlier than expected. If your son finishes his homework in just 15 minutes, you could ask: "Have you already finished your homework?!" because you were expecting it to take more time.
