There are three reasons for the significant gap between Serena and Serena. First, Serena and Serena have been in professional tennis for a year. Second, Venus has been sick since 20 10, so Serena has fallen behind a lot; Third, Serena's strength and potential are even stronger.

(A) Serena and Serena entered the professional tennis world with a time difference of one year.

Serena 1995 entered professional tennis, Venus 1994 entered professional tennis. Although Serena entered professional tennis one year later than Venus, she got a better chance. Although Venus entered professional tennis in 1994, tennis still has devil-level people in 1995, and Venus has little room for development. When Serena entered the professional tennis world on 1995, almost all the demons in the professional tennis world were weak or retired, so Serena got a very good opportunity.

(2) Venus began to get sick at 20 10.

The fundamental reason why the gap between sister flowers in tennis is so large is that Venus' strength declined due to illness after 20 10 years. However, David was diagnosed with xerosis at that time, which directly led to the continuous decline of David's strength and fatal mistakes in many games. David had to choose to rest from the tennis court. In the process of Serena's recuperation, Serena ushered in a new peak in her career, won one grand slam after another, and became a legend in professional tennis.

(3) Serena is stronger.

Although the strength gap between tennis sisters is very small, Serena can use this little gap to create a vast sky. In fact, since 20 10, the tennis sisters are no longer at their peak. During Venus' illness, Serena climbed to the top again with great strength. So Serena has her own reasons for great success.
