t think he meant that science is full of unpredictable or unknowable or supernatural forces. I think that he meant a sense of awe, a sense that there are things larger than us, that we do not have all the answers at this moment, and that we can stand right at the boundary between known and unknown. Scientists are happy, of course, when they find answers to questions. But scientists are also happy when they become stuck, when they discover interesting questions that they cannot answer. That is when their imaginations and creativity are set on fire. That is when the greatest progress occurs. 25. As a child, the author was A. cautious B. generous C. curious D. doubtful 26.

s mind. 27. What is the source of pleasure according to the passage? A. Exact prediction.B. Creativity in experiments. C. Rich imagination.D. Exploration of the unknown. 28. Which of the following is the best title of the passage? A. The Power of Mysteries. B. The Characters of Mysteries. C. The Significance of Science. D. The Beauty of Art. C According to scientists, a study of more than

50 plants and animals suggests their ability to adapt to changes in rainfall and temperature will be vastly outpaced by future climate change. Amphibians, reptiles and plants are harmed more easily in particular, according to US researchers. And tropical(热带的)species are at higher risk than those in temperate zones. Some animals might be able to move geographically to deal with rising temperatures, but others live in remote areas where they cannot move, such as in nature reserves or on mountains or islands. Ecologists analyzed how quickly species had changed their climatic niches (the conditions where they can survive) over time, and how these rates compared with that of global warming. They analyzed populations of plants and animals, including insects, amphibians, birds, mammals and reptiles. Rates of change in climatic niches were much slower than rates of projected climate change, by more than 200,000 fold for temperature on average, they said. Overall, our results show that rates of climatic niche change among populations of plants and animals are remarkably slower than projected rates of future climate change, said Tereza Jezkova and John Wiens, of the University of Arizona. Mammals might be better placed to survive than amphibians and reptiles, because they had the ability to regulate their own body temperatures, said Dr. Wiens. Besides, while some species might be able to move to higher latitudes(纬度) to survive, for a lot of organisms, that is not an option. It'

s a double danger of climate change and habitat destruction, he added. 29. What species are likely to suffer most? A. Mammals in temperate regions. B. Reptiles in temperate regions. C. Mammals in tropics. D. Amphibians in tropics. 30. What does the underlined word they in Paragraph

s the main idea of the passage? A. Human beings should find some ways to fight against climate change. B. Many species will be unable to adapt fast enough to survive climate change. C. Climate change will cause great damage. D. Climate change is increasingly terrible. D From the first days of nursery school to the first days of college, parents and children are faced with feelings brought about by separation. Children of all ages may experience some anxiety about managing on their own. Young children are still struggling to control their impulses(冲动)and may need a parent'
