"Everything happens for the best, "my mother said whenever I faced disappointment, "If you 36 on, something good will happen some day."
Mother was right, as I discovered after graduating from college. I had   37  myself for a sports announcer. So I went to Chicago to knock on the door of every station and was 38  every time. In one station, a kind lady told me that 39  stations wouldn't employ a person without   40 since I had just graduated. "Go out in the town and find a small station that might give you a chance, "she said.
I returned to Dixon, where I had finished my high school education and had  41  in the school football team. My father said that our town had built a store and wanted a man to manage its sports department. The job sounded just 42   for me but I wasn't hired.
My disappointment had 43  as if by design. "Everything happens for the best," Mum  44  me. Dad lent me his car to look for a job. I tried WOC Radio Davenport. The program director told me they had already hired an announcer.  45 I left his office, I asked aloud,"  46 can a fellow get to be a sports announcer if he can't get a job in a radio station?" Suddenly, I heard the director  47  . "Do you know anything about football? " Then he asked me to 48  an imaginary game. It was easy, and I did it without difficulty. The director was 49  and told me I would be broadcasting a game on the   50  Saturday.

The ABO system was discovered by Karl Landsteiner in the early 1900s. He was awarded the Nobel Prize for his achievements. There are four basic types of blood in the ABO system: A, B, AB and O. Everybody is born with one of these four types of blood. We get blood type, just like hair color and height from parents. Because of the substances(物质) contained in each type, the four groups must be transfused carefully, If two different blood types are mixed together, it may put a person into an extremely dangerous situation. Basically, A and B cannot be mixed. A and B cannot receive AB, but AB may receive A or B. In an emergency, type O blood can be given because it is most likely to be accepted by all blood types, so it is often called the universal donor. However, there is still a risk. For the opposite reason, AB is sometimes called the universal receiver. However, because there can be so many reactions in the blood bank of the hospital.
There is a relationship between your blood type and your nationality. Among the Europeans, about 45 percent have type O while 42 percent have type A. The rarest is type AB. Other races have different percentage. For example, some American Indian groups have nearly 100 percent type O out of 100 donors in the world…

He had left his pregnant(怀孕的) wife and his two children  39  at the car and said that he would hitchhike(搭便车) back.
Once I had   40   a can with petrol, I took him back to his car where his two-year-old and four-year-old children were both   41  ,saying that they were cold. Once the car had started, I suggested that he   42   me back.
