　　为什么一些植物会生病甚至死亡(Why Some Plants Become Sickly or Die)

　　There are a variety of factors to be considered when explaining plants become sickly or die. First of all, dryness in the soil causes the leaves to loose freshness, or wilt, and may result in death of the plant.

　　On the other hand, too much water may result in the leaves loosing their strength and drooping, or in their becoming yellow, and occasionally in the rotting of the leaves and stems.

　　While sunshine is necessary for plants, if it is too strong,the soil may be baked and the roots killed. However, if there is no light, the leaves will become pale and the stems thin, and if not corrected, the consequence will be the death of the plant.
