ring space is this geic tendency to expand wherever possible. Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areas can be identified and prepared for. Without knowledge, we may be pletely destroyed by the danger. With knowledge, we can lessen its effects. Exploration also allows minerals and other potential (潜在的 ) resources to be found. Even if we have no immediate need of them, they will perhaps be useful later. Resources may be more than physical possessions. Knowledge or techniques have been acquired through exploration. The techniques may have medical applications which can improve the length or quality of our lives. We have already benefited from other spinoffs including improvements in earthquake prediction, in satellites for weather forecasting and in munications systems. Even nonstick pans and mirrored sunglasses are byproducts (副产品 ) of technological developments in the space, the chance to save ourselves might not exist. While many resources are spent on what seems a small return, the exploration of space allows creative, brave and intelligent members of our species to focus on what may serve to save us. While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds dangers. The danger exists, but knowledge can help human being to survive. Without the ability to reach out across space, the chance to save ourselves might not exist.

People who are thinking about adopting a dog as a friend for their cats are worried that they will fight. A recent research has found a new recipe of success. According to the study, if the cat is adopted before the dog, and if they are introduced when still young (less than 6 months for cats, a year for dogs), it is highly probable that the two pets will get along swimmingly. Twothirds of the homes interviewed reported a positive relationship between their cat and dog. However, it wasn’t all sweetness and light. Th ere was a reported coldness between the cat and dog in 25% of the homes, while aggression and fighting were observed in 10% of the homes. One reason for this is probably that some of their body signals were just opposite. For example, when a cat turns its head away it signals aggression, while a dog doing the same signals submission. In homes with cats and dogs living peacefully, researchers observed a surprising behaviour. They are learning how to talk each other’s language. It is a surprise that cats can learn how to talk ‘dog’, and dogs can learn how to talk ‘Cat’. What’s interesting is that both cats and dogs have appeared to develop their intelligence. They can learn to read each other’s body signals, suggesting that the two may have more in mon than was preciously suspected. Once familiar with each other’s pres ence and body language, cats and dogs can play together, greet each other nose to nose, and enjoy sleeping together in the sofa. They can easily share the same water bowl and in some cases groom(梳理 ) each other. The significance of this research on cats and dogs may go beyond petsto people who don’t get along, including neighbors, colleagues at work, and even world superpowers. If cats and dogs can learn to get along, surely people have a good chance. 31. The underlined word swimmingly in paragraph1 is closest in meaning to______.
