Unit 2 長文問題 Ⅱ ミツバチは女社会? 1 (1) Have è you ever experienced a bee sting? If you (2)have, you may not be fond of bees. However, they are very interesting and honeybee society is very similar to (3) Ours. Let's look at some interesting facts about it. 2 Honeybees live together in groups of 20,000-80,000 in a beehive. This group is [call ] a colony and the bees in the hive can be categorized into three types: a single queen, tens of thousands of worker bees and hundreds of drones. Target ①現在完了形 現在完了進行 ② 名詞・冠詞 人称代名詞 ③受け身 queen bee 3 A queen bee's job is to lay eggs all her life. Each day the lays around 2,000 eggs. The average lifespan of a queen is three to four years. Does the queen "rule" the colony? No. Her duty is simply egg- laying. In fact, the queen bee has a smaller brain than a worker bee. 4 The worker bees are the largest population in the hive. They are all female bees but can't lay eggs. A worker bee's life is rather short. They live around 40 days. Their job is to keep the queen bee happy. They do all the work but change jobs as they grow. For about a week after birth, they mainly clean the hive. Sometime between five to sixteen days after birth, they usually take care of the babies and help to build the hive. When they become twelve to eighteen days old, they carry food. After that, they guard the hive entrance. When they are three weeks old, they fly out the hive, pollinate plants and collect food. 5 If you're a drone bee, life is hard. You're [ bear ], live for a month or two, and then die. During that time, you're not a productive member of the hive-you can't collect pollen or help to look after eggs, like worker bees-and you can't even sting anyone. Drone bees live with one thing in mind: mating with a queen. When (7) can, but they die soon after that. (5) they're lucky, they (6) 6 sting 刺すこと、~を刺す be fond of ~を好む honeybee ミツバチ be similar to 「~に似ている beehive ハチの巣 colony コロニー categorize ~を分類する tens of thousands of 何万もの〜 drone 雄バチ lay eggs 卵を産む lifespan Every bee in the hive has a part to play in the survival and success of their kind.
