5 阅读理解。 In 1983, Jackie Joyner took part in the world track and field championships in Helsinki, Finland. Her first chance to be a world champion ended in disaster, however, when she got injured and could not complete the heptathlon (七项全能). Her brother Al was also present, and he too was injured. Al Joyner said to his sister, "lt"s just not our time yet." One year later, both Jackie and Al Joyner joined the U. S. Olympic team. Having recovered from her injuries, Jackie was a favorite to win the heptathlon. Al, on the other hand, was not considered likely to win his event, the triple jump (三级跳). Surprisingly, Jackie won the silver medal in the heptathlon, missing the gold by only 0. 06 seconds in her final event, the 800-meter run. But Al Joyner became the first American in 80 years to win the Olympic triple jump. The tears running down Jackie"s face at the end of the day were not for her hair"s breadth loss (毫厘之间的失败), but rather for the joy at her brother"s success. The brother knew that Jackie would be back to compete another day. In 1985,Jackie Joyner set a U. S. record with a long jump of 23 feet 9 inches. At that time she was under the guidance of Bob Kersee. Their relationship changed after years spent working together as friends, and they got married on January 11,1986. When Al Joyner married an athlete named Florence Griffith, the stage was set for the emergence (出现) of a track and field family of champions. Both the women were coached (指导) by Bob Kersee in preparation for the 1988 Seoul Olympic Games. At the 1988 Olympics, Jackie Joyner-Kersee not only won the gold medal in the heptathlon, but also took the gold medal in the long jump. Florence Griffith Joyner"s performance was also exciting. She won three gold medals at the Olympic Games in the 100,200 and 4×100 meters relay. 1. By saying "It"s just not our time yet", Al wanted to tell Jackie ______. A. to be careful B. not to be nervous C. not to give up D. to stop doing sports 2. From Paragraph 2,we learn people thought that ______. A. Jackie would win the Olympic heptathlon B.
