5、的想象力，使他能对未来世界进行探索，而且还有着惊人的智力，使他搜寻对现在的和过去的各种事物的解释。阿西莫夫的一生从俄罗斯开始，他生于1920年1月2日。其一生在纽约结束，他于1992年4月6日去世，他是因为9年前的一次输血中感染了艾滋病病毒而去世的。When Asimov was three, he moved with his parents and his oneyearold sister to New York City. There his parents bought a candy store which they ran for the next 40 or so years.
6、 At the age of nine, when his mother was pregnant with her third child, Asimov started working parttime in the store. He helped out through his school and university years until 1942, a year after he had gained a masters degree in chemistry. In 1942 he joined the staff of the Philadelphia Navy Yard
7、as a junior chemist and worked there for three years. In 1948 he got his PhD in chemistry. The next year he became a biochemistry teacher at Boston University School of Medicine.

9、亲怀了第三个孩子，他就开始在糖果店里兼职工作了。他读中学和大学的那段时期都在糖果店里工作，一直到1942年，也就是他获得化学硕士学位一年以后他才停止糖果店的工作。1942年他成为费城海军造船厂的一名初级化学师，并在那里工作了3年。1948年他获得化学博士学位。第二年他在波士顿大学的医学院任生化教员。1958年他放弃了教学工作成为专职作家。It was when Asimov was eleven years old that his talent for writing became obvious. He had told a friend two chapters of a story h

12、小说中的两个章节讲给一个朋友听。这个朋友还以为他是在复述某本书上的故事呢。这使阿西莫夫很惊讶，从那以后，他就开始把自己当做一名真正的作家。1939年，阿西莫夫开始在科幻杂志上发表小说，1950年出版了他的第一部小说，1953年出版了他的第一部科学书籍。Throughout his life, Asimov received many awards， both for his science fiction books and his science books. Among his most famous works of science fiction, one for which he w
13、on an award was the Foundation trilogy (19511953), three novels about the death and rebirth of a great empire in a galaxy of the future. It was loosely based on the fall of the Roman Empire but was about the future. These books are famous because Asimov invented a theoreticalframework which was desi
14、gned to show how ideas and thinking may develop in the future. He is also well known for his collection of short stories, I, Robot (1950), in which he developed a set of three “laws” for robots. For example, the first law states that a robot must not injure human beings or allow them to be injured.
15、Some of his ideas about robots later influenced other writers and even scientists researching into artificial intelligence.Asimov was married twice. He married his first wife in 1942 and had a son and a daughter. Their marriage lasted 31 years. Soon after his divorce in 1973, Asimov married again bu

62、 Wednesday in the JournaloftheAmericanHeartAssociation.One was a lowfat diet that included lots of fruits, lowfat milky products, and small amounts of red meat.

One diet included a daily serving of one avocado, and the other diet had the same amount of fat from other sources.At the end of
64、 the study, the researchers found that the avocado diet led to a big, noticeable drop in LDL compared with the other two diets. LDL is the bad kind of cholesterol (胆固醇), which is found in your blood. Too much LDL in your body may cause heart disease.“I was surprised to see the added advantage of the

70、。由Penny所说的“I was surprised to see the added advantage of the avocado”可知，对于鳄梨的特殊功效她感到非常惊喜，故选B项。4What does the underlined word “caveat” probably mean?AJoke. BChoice.CPity. DWarning.解析：选D词义猜测题。由该词后面的“When its served up with chips, the calories can add up”可知，同时食用鳄梨酱和薯片的话，热量会增高，不利于健康。作者在此提出了警告，故选D项。.语法填空
