【正文】 ds want to know about. How do spacemen in a spacesuit eat, drink, and go to the bathroom? Her answer is “the spacesuit is really a small spacecraft with room for food and watercontainers, and a wastecollection system.” To a high school audience, she might satisfy a curiosity that often arises in her prespeech interviews with students who obviously have seen many science fiction movies. “Do spacemen carry weapons in case they encounter enemies in space?” Her answer is No. To scientists, she might provide technical details on such topics as the design of spacesuits that protects spacemen from the deadly temperature extremes of space. Just as elaborate preparation is required for success in space, Higginbotham says that it’s important for speakers to learn as much as possible about their listeners before a speech because every audience is different. 33. What did Joan Higginbotham do before joining in NASA? 34. How does Higginbotham prepare her speech on space walks? 35. What does the high school audience want to know about space travel? Listening Script Compound Dictation: (31’43’’33’55’’) Crime is increasing worldwide. There is every reason to believe the trend will continue through the next few decades. Crime rates have always been high in multicultural industrialized societies such as the United States. But a new phenomenon has appeared on the world scene: rapidly rising crime rates in nations that previously reported few offences. Street crimes such as robbery, rape, murder and auto theft are clearly rising, particularly in Eastern European countries, such as Hungary, and in Western European nations, such as the Untied Kingdom. What is driving this crime explosion? There are no simple answers. Still, there are certain conditions associated with rising crime. Increasing heterogeneity of population, greater cultural pluralism, higher immigration, democratization of governments, changing national borders, greater economic growth and the lack of accepted social ideas of right and wrong. These conditions are increasingly observable around the world. For instance, cultures that were previously isolated and homogenous, such as Japan, Denmark and Greece, are now facing the sort of cultural variety that has been mon in America for most of its history. Multiculturalism can be a rewarding, enriching experience, but it can also lead to a clash of values. Heterogeneity in societies will be the rule in the 21st century, and failure to recognize and plan for such diversity can lead to serious crime problems.
