The main idea of the first paragraph is ______. [br] Which of the following is true?
选项
A、Algae have existed for more than 430 million years.
B、It is impossible that algae might be the earliest plant on land.
C、Plants get food from animals in the oceans.
D、Evolution began after animals appeared on land.
答案
A
解析
这是一道综合性比较强的题日。必须从第一段和第二段综合考虑才能得出正确的答案。第一段中说:Life on land probably began about 430 million years ago(在4亿三千万年前陆地上才开始存在生命)第二段中说:The first plants to exist out of the water were probably certain kinds of algae(离开水中的生活环境的第一种植物可能是某种海藻类植物)通过这两句话我们可以得出结论:(第一个在陆地上存活的生命)海藻是在4亿三千万年前开始存在在陆地上的。而海藻存在于水中的时间肯定更长。所以海藻存在的时间肯定超过了4亿三千万年。所以本题的正确答案是A。
