Why are the lives of plants not well-known to most people?
Although our lives depend on plants for virtually everything that keeps us alive, their lives remain a secret to most of us. The reason is simple — [11B] plants live on a different time-scale from ours. Although not usually obvious in the relatively hyperactive activities of humans, plants are in constant motion as they develop, search for light and nutrients, avoid predators, exploit neighbors, and reproduce.
Time-lapse photography allows us to easily see the movements of plants and clearly demonstrates that plants are living organisms capable of some extraordinary things. [12A] Time-lapse photography is done by capturing a series of images at intervals ranging from seconds to hours apart. When the images are viewed in rapid succession, much like a flip book, the effect is to compress into a short period, the changes that occurred over a relatively long period of time. The movies on this site show a variety of plants living out their dynamic lives. While we especially hope this site provides material that may captivate the interest of budding plant biologists, even the seasoned plant biologists will find interesting material. New movies will be added to the site as we make or obtain them. However, since making time-lapse movies requires considerable patience, time, and some luck, the rate at which new movies will appear is unpredictable. [13D]Other educational materials are also becoming available on the site. In the meantime, we hope you enjoy the material that is available now.
选项
A、Because plants are not important to people.
B、Because plants’ time-scale is different from ours.
C、Because plants are not in constant motion.
D、Because it is impossible for people to know it.
答案
B
解析
文章一开始就明确提到,人们不是十分了解植物生命活动的事实,原因是plants live on adifferent time-scale from ours(植物活动的时间节奏与人类不同)。
