答案
Week 11 Friday 一、1. B 根据上文“Some plants are as big as tall buildings.”可知，有些植物像高楼一样高大，此处应是对比，说明有些植物很小；选项 B“其他的则像大米一样小”符合语境。故选 B。 2. G 根据上文“Most people can tell the difference between an animal and a plant.”可知，大多数人能说出动物和植物的区别，所以此处应说明能找出区别的原因；选项 G“总的来说，动物可以四处移动，但植物不能”符合语境。故选 G。 3. D 根据上文“But what defines a plant? ...”可知，植物和动物有本质区别，而下文说大多数植物通过开花结果繁殖，所以这里和植物的基本组成部分有关；选项 D“大多数植物都有根、茎和叶”符合语境。故选 D。 4. E 根据下文“For most animals, genes control their growth.”以及后面关于植物生长的描述可知，此段主要讲植物的生长；选项 E“植物是如何生长的呢”符合语境。故选 E。 5. A 上文说基因也控制植物的生长，下文举例说明植物生长环境不同形状不同，所以此处应解释植物的最终形状可能因生长环境的不同而有所差异；选项 A“但是由于它们所生长的地方不同，它们最终的形状可能会有所不同”符合语境。故选 A。 二、1. Plants and animals are both living things with lots of cells. Their growth are controlled by genes. 2. Plants need water, CO₂, and sunlight to make their own food.
