Question

Plants are very important 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(不开花的) plants.

Flowering plants can make seeds(种子). 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(孢子). Spores are very, 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 fall on wet and shady(阴凉的) places, they usually grow into new plants.

1.What fact does the passage lead you to believe?

A. Of all living things, animals are most important.              

B. Spores are seeds.

C. All fruits of flowering plants have seeds.                          

D. Without plants, man will die out.

2.The paragraph following the passage will be about ________.

A. how plants can make food from air                                   

B. how spores grow into new plants

C. why some plants have no seeds                      

D. why non-flowering plants are more important than flowering plants

3.This passage is most likely to be taken from ________.

A. a story book                                            B. a novel

C. a science magazine                                             D. a laboratory report

2.B

3.C

【解析】

试题分析：这篇短文中作者主要介绍了植物在自然社会生活中的重要作用，并且重点介绍了两种不同的植物，即开花的植物和不开花的植物以及各自的特点。

1.细节理解题。根据短文第一段Life could not go on if there were no plants.和Therefore animals and man need plants in order to live. 可知，文章作者意在让我们相信没有植物，人类和动物就无法生存；故选D。

2.推理判断题。根据短文最后一段的最后一句话When these spores fall on wet and shady(阴凉的) places, they usually grow into new plants.可知，文章接下来就应该介绍孢子是如何成长成植物的；故选B。

3.文章来源题。根据短文内容可知，文章介绍的就是植物在社会生活中的重要作用；由此可知应该是来自于科学杂志；故选C。

考点：科普类短文阅读。
