11次の英文を読んで、あとの問いに答えなさい。 Bamboos belong to the grass family. Tall bamboos in a forest look like trees, but they are actually hollow stems. In the old Japanese story Taketori Monogatari, an old bamboo cutter finds a pretty young child in such a bamboo stem. Bamboos grow amazingly quickly. [ A] Ifyou want to grow bamb0os, you first need to make a small deep hole in the ground. [ B ] At the same time, under the ground, a new stem grows out of the planted bamboo, and moves along quickly horizontally. [C ] In spring and early summer, many bamboo shoots come out of the stem under the ground. [ D1 Those bamboo shoots also grow upward fast and become as high as about 20 meters in a few months. In this way, the number of bamboos becomes very large in a few years. All bamboos in a forest are usually clones of the first one, and they are connected to each other by the stems under the ground. So, when the time comes, all bamboos in a forest start to flower at the same time, make their seeds, and finally die out. This is the natural process for grasses. However, many of us won't have a chance to see any bamboo flowers. That is because many kinds of bamboos flower only once every 60 years or more. 1. 次の問題に英語で答えなさい。 (1) Why do all bamboos in a forest start to flower at the same time? e (Because で始めて) (2) Why will many of us NOT see any bamboo flowers? (Because で始めて) 2. 下の英文を入れる最適な場所はどこか、A~Dの記号で答えなさい。 Tpou When you plant a young bamboo there, it usually grows upward fast. Bryeqebact n or bnos scort ( )odw 2cgica
