Ａ
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 Oregon State College in 1922. He had chosen to study this 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 substances”. 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 War II, 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 Ｎｕｃｌｅａｒ－Ｔｅｓｔ－Ｂａｎ 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 Prize for Peace.
56. From the first paragraph, we learn that Linus Pauling ______________. A. didn't study hard while in Washington High School B. is the only scientist who has won two Nobel Prizes C. was once badly treated in Washington High School D. chose to study chemical engineering to earn his living
57. Which of the following things did Pauling pay much attention to at first? A. The “behavior” of molecules. B. Physical chemistry. C. Biological chemistry. D. The human body.
58. During World War II, Linus Pauling ___________. A. had to stop his research because of the war
B. made great contributions to the safety of the country C. joined the army to fight for the safety of the country D. took part in researching nuclear bombs
59. Which of the following is legal according to Ｔｈｅ Ｎｕｃｌｅａｒ－Ｔｅｓｔ－Ｂａｎ Ｔｒｅａｔｙ?
A. The use of nuclear weapons.

There is no best way to learn a language, just different ways that suit different people. Some people prefer to “pick up” the language by reading books or magazines, watching films, visiting the country where the target language is spoken, etc. They focus on the meanings of words and don't worry too much about the language forms used. This method often suits children if they find themselves in a foreign country or with foreign friends. However, this approach doesn't suit everyone if your aim is to become good at writing.
Probably the most common way to learn a language is in a classroom with a teacher. The teacher can explain difficult words, give guidance, provide extra motivation and feedback on progress. Unfortunately, some people do not have very pleasant experiences of learning a language in the classroom. Language learning can be great fun. But your writing level will be increased most efficiently this way. Besides learning in a classroom, you can use a personal tutor and arrange a very flexible system of tuition. That means if you are busy at a particular time, you can still arrange to have your language tuition at a time that suits you.
