Underline each verb phrase in the following paragraph. Draw a second line under the helping verb. EX. 1. Have you ever played tennis? [1] Tennis can be traced back to an old French game. [2] Over the years, the rules of the game have remained largely the same. [3] However, the players' equipment has changed greatly. [4] During the twelfth and thirteenth centuries, players would hit the ball with the palms of their hands. [5] The sheepskin ball was filled with sawdust. [6] Later, pieces of wood and gloves were used instead of hands. [7] By the middle of the fifteenth century, strung rackets had been invented. [8] Today, many professional players do not use wooden rackets. [9] Modern racket frames are made from a combination of materials, such as fiberglass, graphite, and metal. [10] Different kinds of stringing have also been tried.
