【解析】

本文是一篇说明文，介绍了一些关于森林的知识。

【1】句意：森林像一块绿色的地毯覆盖着地球。

根据句子结构可知，空格处应填入动词作谓语，只有B选项covered“覆盖”为动词过去式，符合句子结构，故选B。

【2】句意：这不难发现，因为那片古老森林的一部分仍然屹立不倒。

根据句子结构可知，空格处应填入形容词作定语，修饰名词forest，将C、E选项都带入句中可知C选项ancient“古老的”更为符合句意，故选C。

【3】句意：但对有些树来说，长高并不容易，因为只有很少的阳光照射到它们身上。

结合前文All the trees are very tall. The young trees are up to 60 feet high可知，本句说的也与树的高度有关，故句意应为“但对有些树来说，长高并不容易，因为只有很少的阳光照射到它们身上”，E选项taller“更高的”符合句意，故选E。

【4】句意：在这片树木繁茂的森林里，不仅有丰富的植物生命，还有丰富的动物生命。

not only ... but (also) ...为固定搭配，意为“不仅……而且……”，符合句意，故选D。
