Question

　　How does a bee tell the others where to find the flowers it has discovered?

　　In the early 1900s, Austrian naturalist Karl von Frisch puzzled over this curious problem. Fascinated with the ways honeybees worked together, Von Frisch began a deep study of their activities when they returned to their home called a hive. Von Frisch discovered that bees express themselves not only by feeling and tasting, but also by dancing. There was a means by which a bee communicated to other bees that it had found food. That was dance!

　　In fact, bees do two kinds of dances to tell other bees of their food discovery. First, there is a circle dance, in which the bee moves in a circle inside the hive. The circle dance is used when the food is not more than ten meters away. The second kind of dance done by the bee is a waggling dance. That is to say, the bee waggles the end of its body as it moves in a straight line, then it turns in a semicircle, runs straight again. The waggling dance is used when the food is more than ten meters away. Meanwhile, in the two dances, other bees gather around and closely follow the dancer. They smell the dancing bee that has found the food. The smell tells them where to find the flower and also what kind of flower to look for. For this really interesting work, Karl von Frisch won a Nobel Prize.

Answer 1

答案：D;C;A
解析：

1．本题考查对文中提供信号的准确理解。由短文第二段中bees express themselves not only by feeling and tasting, but also by dancing可知，答案选D。 　　2．这是一道细节题。短文倒数第二段第二句中the bee moves in a circle inside the hive说明，圆圈舞是蜜蜂找到食物后在蜂房内跳的，目的是为了告诉其他蜜蜂食物所在。 　　3．这是一道正误辨认题。综合短文第二段中Von Frisch began a deep study及There was a means by which a bee communicated to other bees 这两处信息，就可以判断出A项正确。
