The second biggest rainforest is the Congo Rainforest in Africa. Everything seems bigger in the rainforest. You can find huge trees and plants with large leaves there. 55
Rainforests have more species(物种) of plants and animals than anywhere else on earth. 56 More than half of the world’s animals live there too.
57 Because of the warm and wet conditions. Most rainforests are along or near the equator(赤道). It never snows and the temperature never drops much below about $20°\mathrm{C}$. Some places get about 2.5 cm of rain or more every day. 58 When plants grow well,animals have lots to eat.

【分析】
本题是阅读句子还原题，解题思路为：先通读短文把握整体内容，再结合空格前后的语境、句子间的逻辑关系，匹配对应选项。步骤如下：1. 分析54空前后内容，确定对应选项；2. 分析55空前后话题，匹配衔接句；3. 分析56空的上下文逻辑，选择补充句；4. 分析57空的设问与答句对应关系；5. 分析58空的因果衔接，确定最后选项。
【解析】
1. 54空：前文提到“存在多个雨林”，后文说明“超过一半的雨林在巴西”，B选项“The biggest rainforest is the Amazon Rainforest.”（最大的雨林是亚马逊雨林），衔接上下文对最大雨林的描述，故54选B；
2. 55空：前文提到“雨林里有巨大的树和大叶子植物”，A选项“The tallest trees may grow as tall as 61 metres.”（最高的树可达61米），延续“树”的话题，补充树的高度信息，故55选A；
3. 56空：前文说明“雨林有最多的动植物物种”，后文提到“超过一半的动物在雨林”，E选项“You might find as many as 300 kinds of trees in a rainforest.”（雨林里能找到多达300种树），补充植物物种的信息，衔接后文的动物内容，故56选E；
4. 57空：后文是because引导的原因句，说明前文应为问句，C选项“Why is there so much life in the rainforest?”（为什么雨林里有这么多生命？），符合“设问+答因”的逻辑，故57选C；
5. 58空：前文提到“雨水多、温度高”，后文说明“植物长得好”，D选项“All the rain and warmth help plants grow.”（所有的雨水和温暖帮助植物生长），衔接“气候条件→植物生长→动物有食物”的因果链，故58选D。
