Question

We must do what we can to protect the plants because plants are very important for living things. Life could not go on if there were no plants. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals get their food by eating plants and other animals. Therefore animals and man need plants in order to live. This is why we find that there are so many plants around us.

If you look carefully at the plants around you, you will find that there are two kinds of plants: flowering plants and non-flowering plants. Flowering plants can make seeds. The seeds are protected by the fruits. Some fruits have one seed, some have two, three or four, and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit. Most non-flowering plants do not grow from seeds. They grow from spores（胚芽）. Spores are very small. Some spores are so small and light that they can float in the air. We may say that spores are quite the same as seeds. When these spores are all on wet and shady places, they usually grow into new plants.

Answer 1

【答案】

 

1.B

2.A

3.D

4.C

5.D

【解析】

1.细节理解题。根据第一段的第三句话：“plants can make food from air,  water and sunlight. ”可知，答案选B。

2.主旨大意题。根据第一段的前两句话可知植物对于生命是很重要的，接着给出了原因，动物不能制造食物，只能吃掉植物或动物，只有植物能够利用空气、阳光和水制造食物，所以答案选A。

3.推理判断题。通读全文可知，植物能够利用空气、阳光和水制造食物，动物不能制造食物，只能吃植物或动物，离开了植物，动物包括人类都要死亡，故选D；文中没有突出动物的重要性，故A是错误的；孢子和种子是两种不同的繁殖方式，故B是错误的；香蕉这种开花植物的果实就没有种子，故C是错误的。

4.推理判断题。本文讲述的是植物的重要性以及繁殖方式，很显然是一篇科普文章，故选C。

5.推断词义题。结合常识可知，有果实的植物种子往往在果实内部，果实起着保护种子的作用。所以protected应是“保护”的意思，有guarded相近。
