There is a lot of talk these days about how kids should be interested in science. Here's an area of science for everyone, and these cool new books might inspire you to discover your inner scientist. Scaly Spotted Feathered Frilled by Catherine Thimmesh, 58 pages, ages 9-12 Seeing a picture or a model of a dinosaur, do you wonder how anybody knows what they look like? After all, nobody has seen a living dinosaur. This book explains how scientists and artists work together to re-create dinosaurs. As scientific discoveries have been made, the models have changed. Scientific tests may one day expose what a dinosaur's coloring was, but now artists have to use their imagination to determine how these huge creatures looked. Beyond the Solar System by Mary Kay Carson, 128 pages, ages 10-13 This book takes readers back to the beginnings of space exploration--thousands of years ago, when people began star observation--and forward to today's search for planets in distant parts of the Milky Way. Along with history lessons, readers get 21 activities, such as making a black hole and creating a model of Albert Einstein's universe using a T-shirt. The activities are perfect for cold winter days. Ultimate Bugopedia by Darlyne Murawski and Nancy Honovich, 272 pages, ages 7 and older If you're always on the lookout for butterflies, this book is for you. Hundreds of color photos of common and unusual insects fill this hardcover. There are fascinating stories related to the photos. For example, do you know an insect feeds on the tears of Asian cattle? There's a question-and-answer section with an insect scientist and advice on how to help preserve endangered insects. Journey Into the Invisible by Christine Schlitt, 80 pages, ages 9-12 If you use a magnifying glass, you know a leaf looks quite different. This book explains what microscopes do and then shows what happens to things around the house when watched with this amazing scientific tool. The bacteria in your mouth, when magnified 20,000 times, look a bit like swimming pool... From the passage, we can learn that _ . A) butterflies are fond of the tears of Asian cattle B) scientists have discovered the dinosaur's coloring C) microscopes can present you with an amazing world D) man has explored the black hole for thousands of years

Normally a student must attend a certain number of courses in order to graduate, and each course that he attends gives him a credit, which he may count towards a degree. In many American universities the total work for a degree consists of thirty-six courses, each lasting for a term. A typical course consists of three classes per week for fifteen weeks; while attending a university a student will probably attend two terms a year. It is possible to spread a period of work for the degree over a longer period. It is also possible for a student to move between one university and another during his degree course, though this in fact is not done as a regular practice. For every course that he follows a student is given a grade, which is recorded and available for the student to show employers. All this imposes a constant pressure and strain of study, but in spite of this some students still find time for great activities in student affairs. Elections to positions in the student union arouse great interests. Students who are qualified usually perform the effective work of the student union. With the big numbers of students, the operation of the system does involve a certain number of activities. A student who has held one of these positions in the union is much respected and it willbe of benefitto him. Which of the following is unlikely to be inferred from the passage? A) A student can get two degrees from different universities at the same time. B) A student is allowed to study in two specific universities. C) A student may continue to study for degree while working. D) It is possible for a student to take five years to get a degree.

Ques: *Put sunscreen on before going out in the sun. *Take it with you. *Use it -- after a swim. -- every hour or so while playing outdoors. -- if you get sweaty. *Cover up when the sun is overhead -- 10 a.m.--2 p.m.. -- especially at lunch time. *Get your suntan gradually and not too much. *Controlled exposure to sunshine helps avoid skin cancer. Ask your chemist to recommend a suitable sunscreen. Queensland Cancer Fund P. O. Box Spring Hill, QLD.4000 Phone (07) 8397077 Provided for community awareness by the Queensland Cancer This passage is most likely to be _ . A) an article from a student text book B) a direction from a bottle of medicine C) a suggestion from a chemist D) an advertisement from a newspaper
Ans: D
Ques:Ronald Hoffman born in 1937 is Polish-born American organic chemist and Nobel laureate . As a theoretical chemist, Hoffmann studied energy levels in chemical bonds during chemical reactions. He put computers to use to solve his problems and, despite the complexity of his research, was able to explain his theories and discoveries to the non-specialist. For his work he was awarded the 1981 Nobel Prize in chemistry, which he shared with Fukui Kenichi. Born in Poland, Hoffmann settled in New York City as a child and became a United States citizen. He received his undergraduate degree in premedical studies from Columbia College in 1958. He attended Harvard University, where he received his PhD. degree in chemical physics in 1962. He joined the faculty of Cornell University in the mid-1960s and remained there throughout his career. Hoffmann and Nobel laureate chemist Robert Burns Woodward developed rules, based on quantum mechanics, to determine how energy levels in atomic electron orbits influence how a chemical reaction takes place. These simple rules, known as the Woodward-Hoffmann rules, allowed chemists to predict reaction results and was quickly accepted and put to use in a wide variety of situations. Hoffmann later turned his research to a variety of problems related to discovering the molecular structure of inorganic and organometallic compounds. Hoffmann is also known for what is called the Isolobal Analogy, which is yet another discovery linking all areas of chemistry. It is useful in predicting the behavior of new molecules based on the orbit structure of the components used to form them. Aided by computers, Hoffmann was able to _ a vast amount of data to support his ideas. Unlike the scientific papers of many chemists, Hoffmann's publications contain little raw data but instead are filled with diagrams and pictures to explain his results. His drawings of shaded balloons to indicate eigenvectors, a unit used in mathematics, are now the accepted scientific notation for illustrating this value. How did Hoffman make his research popular? A) He applied some computer skills to help explain his ideas. B) He established a special computer system to help. C) He drew some forms explaining his ideas. D) He did series of experiments to prove his ideas.
