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 occasion-ally 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 con-sequence will be the death of the plant.

为什么有些植物会生病或死亡?
解释为什么有些植物会生病或死亡这个问题，有很多因素值得考虑。
首先，土壤干燥致使叶子失去水分或枯萎，最终有可能导致植物的死亡。
相反,太多的水分有可能使叶子失去力量，向下垂落，或变黄，有时叶子或茎部变腐坏死。
虽然阳光对植物是非常必要的，但如果阳光过强，土壤就会被烤干，根会被烧死。然而，如果没有阳光，叶子就会长得苍白无力，茎部会变得细嫩单薄。若得不到及时的更正，结果只有死路一条。
