[范文1]

Shooting, originated as a means of survival, developed into a sport only in the late 19th century. The sport first appeared in 1896, but none were contested during the 1904 and 1928 Games. The sport returned to the Olympics in 1932. Women were first allowed to compete in the Olympic shooting in 1968. The sport has grown steadily from just three shooting events at the 1896 Olympic Games to 17 today.

[范文2]

It was not until the end of 19th century that shooting, originated as a means of survival, earned its status as a sport. Shooting became an Olympic event officially in 1896. Yet, twice in history (1904,1928) shooting was suspended at the Olympics. It returned to the Games in 1932, and women were first allowed to participate in the competition in 1968. The sport has been growing steadily from 1896‘s three events to today’s seventeen.
