【解析】

本文是一篇說明文，介紹了一些關于森林的知識。

【1】句意：森林像一塊綠色的地毯覆蓋著地球。

根據句子結構可知，空格處應填入動詞作謂語，只有B選項covered“覆蓋”為動詞過去式，符合句子結構，故選B。

【2】句意：這不難發(fā)現(xiàn)，因為那片古老森林的一部分仍然屹立不倒。

根據句子結構可知，空格處應填入形容詞作定語，修飾名詞forest，將C、E選項都帶入句中可知C選項ancient“古老的”更為符合句意，故選C。

【3】句意：但對有些樹來說，長高并不容易，因為只有很少的陽光照射到它們身上。

結合前文All the trees are very tall. The young trees are up to 60 feet high可知，本句說的也與樹的高度有關，故句意應為“但對有些樹來說，長高并不容易，因為只有很少的陽光照射到它們身上”，E選項taller“更高的”符合句意，故選E。

【4】句意：在這片樹木繁茂的森林里，不僅有豐富的植物生命，還有豐富的動物生命。

not only ... but (also) ...為固定搭配，意為“不僅……而且……”，符合句意，故選D。
