3. What is tennis?
Tennis is a sport that is practiced in a plain,
rectangular, divided by an intermediate network,
which is called track. It is played between two
players (singles) or between two pairs (doubles)
playing with rackets and balls. You must hit the ball
with the racket to go from side to side of the field
passing over the network.

4. Origin
The Egyptian, Roman, Greek and Perona played similar games of
tennis. The first references about tennis are of
Peralandia, named 'Peter Pears' because initially the people hit
the ball with the pear. Later he began to use rackets. The original
tennis courts played on natural grass. It originated in Europe and
it expanded at first by the English speaking countries, especially
among the upper classes. Today's tennis has become
universal, and is played in almost every country in the world.

5. Rules of the Game
A game of tennis starts with the service of one of the players, who
must hit the ball so that it bounces on the opposite side, that is, if
a player draws from his right, the ball must bounce in the box to
the left of the network. For each point the player has two
opportunities, if the first fails, he has another chance. After both
players must throw the ball alternately from one field to another
in search of his opponent to return the ball before it bounces
twice, if this happens, you get a point.
if you win 4 points , you get a game, and if you win six games you
get a set.

6. Measurements of the track
Tennis is played on a rectangular track. Her measurements
vary depending on the modality in which you play (single or
double).
To measure individual measures 23.78 meters of long and
8.23 meters in width. In doubles, the length is the same and
the width is 10.97 meters. These limits are marked by lines
that are considered part of the track. The net divides the
court into two halves for the opponents. On each side of the
net there are two rectangles, measuring 6.40 meters of long
and 4.11 meters in width, which serve only to determine
whether a goal is valid or not.

7. Ranking
Currently the players are arranged in a kind of ranking called "ticket system"
(Entry Ranking), which add up the points scored by players in the past 52
weeks, which is approximately one year. Therefore, at the end of each week,
are subtracted to each player the points obtained in the same week last year,
and the cattle are added in the current week.
