Certain plant species won flower if they sense too much light and some plants will only flower if they sense a specific amount of light.某些植物种类如果感觉到了太多光就不开花,而有些只有感觉到了一定程度的光才会开花。
The new bulbs require less than half the electricity consumed by the conventional bulbs currently used to produce the same amount of light.这种新灯泡的耗电量还不到目前用于生产相同亮度的传统灯泡的一半。
