Children's Books: Hawking's fact and fiction
George F. R. Ellis & Ruby
BOOK REVIEWED-George's Secret Key to the Universe
by Lucy & Stephen Hawking
Stephen Hawking's book A Brief History of Time was a huge commercial success. Its achievements in bringing difficult scientific ideas to a wide audience are not so clear. Now the distinguished physicist has teamed up with his daughter Lucy to produce a children's book designed to communicate contemporary physics. Will it capture the attention of young minds and teach them some real science? Or will it be boring and over the heads of the prospective readers?
George's Secret Key to the Universe is an adventure story complete with villains and hero and is illustrated with enjoyable line-drawings. It involves a lost pig, a humorously portrayed intelligent computer, school bullies and a trip through the Solar System. Didactic discussions on aspects of modern physics, such as supernova explosions and black-hole physics are hung on this set-up. There are also fact boxes on physics and astronomy, and some photographs of astronomical phenomena: planets, comets, galaxies and so on. Overall, the book is a serious effort to convey facts and ideas in present day astronomy and astrophysics, within a science-fiction adventure story.
The mixture is great. Children love facts and adventure stories. The combination will catch their interest and keep them occupied for hours. After ten minutes of leafing through the book, my granddaughter Ruby was deeply absorbed and I had to promise to bring it back for her to read after I had completed my review. Like any educational tool, it will succeed for some and not for others. I suppose there should be more of the former.
41. Where do you think this passage is taken?
A. From a news story. B. From a textbook.
C. From a book review. D. From an advertisment.
42. Which of the following books is mainly reviewed in this passage?
A. George's Secret Key to the Universe B. A Brief History of Time
C. The Nature of Space and Time D. Hawking's fact and fiction
43. What is the author’s attitude towards the book being reviewed?
A. It will be less successful. B. It will be more successful.
C. It will be a complete failure. D. It all depends on Ruby
44. The underlined word “leafing” (in the last paragrph) probably means ______.
A. adding leaves to a book B. throwing away a book
C. tearing up a book D. turning pages of a book
B
Exercise, such as walking, can reduce the risk of diabetes (糖尿病) in people whose blood sugar is starting to rise. That outcome was shown in a large study. Despite trying hard, those who dieted and worked out lost very little weight. But they did manage to maintain a regular walking program, and fewer of them went on to develop diabetes.
Exercise also may reduce the risk of heart disease. There seems to be some effect: Most of the heart protection appears to be realized by walking regularly. More intense exercise has been shown to provide only slightly greater benefits.
Active people are much less likely to smoke; they’re thinner and they eat differently than people who are less active. They also tend to be more educated, and education is one of the strongest predictors of good health in general and a longer life. As a result, it is impossible to know with confidence whether exercise prevents heart disease or whether people who are less likely to get heart disease are also more likely to be exercising.
Still, in rigorous studies in which elderly people were assigned either to exercise or maintain their normal routine, the exercisers were less likely to fall, perhaps because they got stronger or developed better balance. Exercise may prevent broken bones—but only indirectly.
