Linus Pauling，the only person who has won two undivided Nobel Prizes，was born in Portland，Oregon. He attended Washington High School but because of an unimportant detail he did not receive his diploma until 1962，long after he had received his Bachelor’s degree in chemical engineering from Orgon State College in 1922. He had chosen to study his major because he could get a good job with it.
He won the Nobel Prize for Chemistry in 1954 for his research into the nature of the chemical bond and its application to the explanation of the structure of complex substance. His interest in the “behavior” of molecules(分子) led him from physical chemistry to biological chemistry，especially of the human body. He began with proteins and their main parts，the amino acids(氨基酸)，which are called the“building blocks of life”．In 1950，he constructed the first satisfactory model of a protein molecule，a discovery very important to the understanding of the living cell.
During World WarⅡ，Pauling was a member of the Research Board for National Security，for which he was awarded the Presidential Medal of Merit in 1948. However，the use of the atomic bomb near the end of the war turned Pauling in a new direction. Having long worked on the structure of molecules，he took an immediate interest in the deadly effects of nuclear fallout on human molecular structures.
From then on，Pauling protested the production of the hydrogen bomb and supported the prevention of the spread of nuclear weapons. Through his efforts，The NuclearTestBan Treaty，declaring all nuclear tests to be illegal except underground ones，came into effect on October 10,1963，the same day Linus Pauling was awarded the Nobel Peace.

Returning from a trip overseas, I sensed that something was wrong between Keith, one of my two sons, and me. So I asked him, “Keith, have I done anything that really 41 your feelings?”

“And you didn’t do it?” I asked.
“No, I didn’t. I was just searching for my gift.”
My heart sank. I felt 54 . I hugged Keith and asked him to 55 me. His honesty made me think of my other son, Kevin. Maybe I’d hurt his feelings, too. I went to ask him the 56 question. Kevin answered as immediately as his 57 , “Last Christmas you promised us a special toy, but you forget about it.”
58 Christmas had passed, I took my two sons to the store that day and bought them what I had promised. The 59 thing wasn’t the toy. The problem was that I’d made a promise too 60 and didn’t keep it as their mother.
