一个英文句子中的一部分我不理解……………………………………
During the race,Keino was so focused on competing against American ace Jim that,in retrospect,"without watching a video,I would not know what happened at the finish."
请问：句中的that在这里是干什么用的（请具体说明）?引号引起来的部分是Keino说的话吗?
原文在这里：
Kipchoge Keino is a modest man,and it takes some prodding to get the great Kenyan runner to recall how he felt on Oct ,20,1968-when he won his first gold medal,in the 1,500meters in Mexico City.The day hadn't start out well ,Keino was suffering from stomach pains that later turned out to be a severe gallbladder infection.His doctors advised against running ; he ignored them.During the race,Keino was so focused on competing against American ace Jim Ryun that ,in retrospect ,"without watching a video ,i wouldn't know what happened at the finish ."He does remember what happened next ." I can an honor lap.i ran it to celebrate and to let my body recover .i felt overcome by the excitement ." It was not the only memorable event in his life that day.Back home ,his wife ,Phyllis ,gave birth to their third daughter ,named Milka Olympia Chelagat in celebration of her father's victory .
Keino went on to win a silver medal in the 5,000 meters in Mexico City and a gold and a silver four years later in Munich .He then become Kenya's Olympic running coach from 1976 to 1986,futhering his nation's dominance in distance events.Kenyan runners have captured 32 Olympic track medals since 1964 and won the last six consecutive Boston Marathons.This summer ,Keino will be in Atlanta as chief of the 120-athlete Kenyan delegation ,wich could include his son Martin ,23,a former NCAA5,000-meter champion at the University of Arizona,hoping to qualify for the 1,500 meters.
But Keino's athletic accomplishments are not the only reason he is a hero in the town of Eldoret in northwestern Kenya.Thirty years ago,Keino and his wife-who now have seven children of their own - began taking orphans into their home .Their house became so crowded that they raised funds to build a dormitory and a dining hall on a nearby farm Keino owns.Income to support the facility comes from the farm,his sports shop and fees he has received from the Kenyan government over the years.Today ,73 children and youny adults-aged 2 to 22-live on the farm." i think i have been lucky," Keino says."Now what is important is how i use what i have to help others."
如果是so……that……句型的话，that后面应该接从句，既然是接从句，那就应该是间接引语呀，难道真的也可以是直接引语吗？

其实句子主干就是Keino was so focused that …….只不过focus 后面接了介词on +competing against American ace Jim.其实这个句子整体结构不难,你应该见过类似的.比如,I was so surprised that I jumped from the chair.
