Plants and Mankind
Botany (植物学), the study of plants, occupies a peculiar position in the history of human knowledge. We don’t know what our Stone Age ancestors knew about plants, but from what we can observe of pre-industrial societies that still exist, a detailed learning of plants and their properties must be extremely ancient. They have always been enormously important to the welfare of people, not only for food, but also for clothing, weapons, tools, dyes, naedicines, shelter, and many other purposes. Tribes living today in the jungle of the Amazon recognize hundreds of plants and know many properties of each. To them botany has no name and is probably not even recognized as a special branch of "knowledge" at all.

[单项选择]Between the eighth and eleventh centuries A.D., the Byzantine Empire staged an almost unparalleled economic and cultural revival, a recovery that is all the more striking because it followed a long period of severe internal decline. By the early eighth century, the empire had lost roughly two-thirds of the territory it had possessed in the year 600, and its remaining area was being raided by Arabs and Bulgarians, who at times threatened to take Constantinople and extinguished the empire altogether. The wealth of the state and its subjects was greatly diminished, and artistic end literary production had virtually ceased. By the early eleventh century, however, the empire had regained almost half of its lost possessions, its new frontiers were secure, and its influence extended far beyond its borders. The economy had recovered, the treasury was full, and art and scholarship had advanced.

[单项选择]Bees are insects. They live all over the world except where it is very cold . Bees do not like ice and snow. They are the only insects that make food that you and I can eat. We eat their honey and also use their wax for making things.
Bees live in a hive. They live in hundreds of little rooms made of wax. It is in these rooms that the queen bee lays her eggs. As each egg hatches out it becomes a larva. This larva lives in a room and is fed by other bees. Every bee does a job without being told. Some make wax, others fan the hive to keep it cool. Then there are the bees that fetch nectar from the flowers. The nectar is turned into honey inside the bee that puts it into room as food for the larva or gives it to another bee. The queen bee is larger than the other bees. There is only one queen in a hive. If other queens are born, they are killed. While she keeps laying eggs, she is looked after by the worker bees.
Bees live in the hive, which is made of wax.
