Read the passage. On a piece of paper, take notes on the main points of the reading passage.

Many species of Asian bamboo have rather unique flowering and seeding cycles. What makes these cycles unique is that all the members of a species tend to flower and then seed at the same time; something else that is unique is that these simultaneous seeding cycles generally occur at rather lengthy intervals of perhaps fifteen to sixty years or more. This means that a particular species of Asian bamboo may not flower and seed for many, many decades and then, when this species does flower and seed, all of its members tend to flower at the same time and then simultaneously set tremendous quantities of seeds before they die so that the seeds can grow into new plants.

One particular species of Chinese bamboo is a rather extreme example of the unique flowering and seeding cycles of Asian bamboo. This species tends to flower and seed less than once a century, and, when it does flower and seed, it does so throughout the world. This special Chinese species is known to have flowered and seeded in the early 1700s and in the mid 1800s and then once again in the late 1960s. Its twentieth century flowering was quite well documented and showed how amazing the species’ flowering and seeding cycle is. Astoundingly, when this species of bamboo flowered and seeded in the late 1960s, it flowered and seeded in widely divergent areas; the flowering and seeding of this species of bamboo was noted in many parts of the world, including northern and southern Asia, North America, South America, and Europe.

(professor)

A particular problem that attracted a lot of attention in the second half of

the twentieth century is how the survival of the giant panda is related to the unusual flowering and seeding cycle of Asian bamboo. The giant

panda still lives in the wild in only a few mountain ranges in the

southwestern part of China because its survival has been threatened both by hunters and by the destruction of the habitat it needs to survive.

What has been noted in the last few decades is that the panda’s survival is also threatened by the flowering and seeding cycles of the bamboo where the pandas live. Here’s what the problem is. Bamboo is the main source of food for the giant panda. However, when there’s a massive flowering and seeding of the bamboo, the bamboo that has just seeded dies, and there’s

a lag of quite a few years before the new young seedlings grow enough to

provide food for the giant panda. When the bamboo where the giant

panda’s living dies, the giant panda needs to move to new areas to find

food. The search for food has led the giant panda into areas that are more settled and more full of danger for the giant panda.

HOW IS THE INFORMATION IN THE LISTENING PASSAGE ABOUT THE GIANT PANDA RELATED TO THE IDEAS IN THE READING PASSAGE ON ASIAN BAMBOO?
