A lady and her husband stepped off the train in Boston.They walked without an appointment(预约)into the outer office of Harvard’s president.But they were       by his secretary and kept waiting.For hours,the secretary took no notice of them,     that the couple would finally become       and go away.But they didn’t.The secretary finally decided to disturb the president,though unwillingly.
A few minutes later,the president walked towards the couple with a       face.The lady told him,“We had a son that        Harvard for one year.He loved Harvard.He was happy here.But about a year ago,he was accidentally killed.My husband and I would like to       a memorial(纪念物)to him,somewhere on campus.”
The president wasn’t moved .Instead,he was shocked.“Madam,” he said,“we can’t put up a statue for every person who studied at Harvard and     .If we did,this place would look like a cemetory,” “Oh,no,” the lady explained quickly “We don’t want to put up a statue.We would like to give a building to Harvard.”The president rolled his eyes and      at the couple and then exclaimed,“A building! Do you have any idea how much a building costs? We have spent over $7 500 000 on the campus building at Harvard.” For a moment the lady was silent.The president was       ,because he could get rid of them now.Then the lady turned to her husband and said quietly,“Is that all it costs to start a university? Why don’t we just start our own?” Her husband nodded.Since their offer was turned down,Mr.and Mrs.Stanford traveled to California where they founded the University that bears their         ,a memorial to a son that Harvard no longer cared about.
