Because of this, it can be difficult for scientists to learn about these animals. In order to study black bears, researchers from New Jersey, USA, catch bears and use drugs (毒品) to help them go to sleep. Researchers then work out the size and the weight of the bear, take blood to test for diseases, remove a tooth and take it to the lab to find out its age. From these studies, researchers want to find out how many bears live in New Jersey, how long they live, and how many babies they produce. But in Minnesota, USA, researchers study bears that are completely awake. The bears know the researchers voices and they are not afraid of die research team. With the help of a few grapes to keep the bears busy, researchers can touch them to check their hearts, look at their teeth , and do other jobs. Researchers can also walk or sit with bears for hours and make videos to learn about their everyday lives. In both places, the main purpose is the sameto make sure there is a healthy population of black bears. But the research methods and the kinds of information that researchers, are able to collect are quite different.【小题1】 In the first paragraph, we can learn that North American black bears are _.

But in fact the umbrella was not invented as protection against the rain. Its first use was as a shade (遮蔽) against the sun. Nobody knows who first invented it， but the umbrella was used in very ancient times. Probably the first to use it were the Chinese， back in the eleventh century BC. We know that the umbrella was used in ancient Egypt and Babylon as a sunshade. And there was a strange thing connected with its use : it became a symbol of honor and power(权力). In the Far East in ancient times， the umbrella was allowed to be used only by those in high office or by royal people such as the kings or queens. In Europe， the Greeks were the first to use the umbrella as a sunshade. The umbrella was in common use in ancient Greece， but it is believed that the first people in Europe to use the umbrella as protection against the rain were the ancient Romans. During the middle ages in Europe， the use of the umbrella almost disappeared. Then it appeared again in Italy in the late sixteenth century. And again it became a symbol of power. Umbrellas have not changed much in style during all this time， though they have become much lighter in weight. It wasnt until the twentieth century that the umbrellas for women began to be made in all kinds of colors.【小题1】Ancient people first used umbrellas as _.
