Life on land probably began about 430 million years ago, though it has existed in the water for perhaps as much as 3,000 million years. When we think of the first     1    on land, we     2   think of strange animals coming out of the oceans, but, in fact, no animals could have been living if plants had not been on land first. Plants had to be on land before animals arrived. They    3   the first land animals with the    4   and food necessary, since they ---the plants are the only form of life that is able to get and store    5    .

【解析】

试题分析：本文向我们介绍了世界上的第一批生命是出现在海洋里，紧接着慢慢地在海洋的周围有一些近海的植物，然后出现了陆地上的植物，这样陆地上的植物就为动物的出现提供了生存环境及食物，随之，世界上的森林就多了起来。

 根据Life on land probably began about 430 million years ago,这里提到生命，上下文的呼应，故选J。

 根据but, in fact, no animals could have been living if plants had not been on land first.我们很可能想起陆地上的生命是动物，而实际上不是，故选F。

 这是动词短语supply…with为……提供，植物为第一批的动物提供生存环境和食物，故选I。

 植物为第一批的动物提供生存环境和食物，故选H。

 根据我们的常识，植物是能够得到和储存能量的，故选E。

 藻类之后的第一批植物也是需要接近水，来进行繁殖，故选D。

 根据我们的常识植物发展了它们的根，故选A。

 因为植物需要长高去吸引阳光，故选G。

 是短语be covered with 被……所覆盖，世界上覆盖着森林，故选C。

考点：这是一篇说明文。
