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(不開花的) plants.

Flowering plants can make seeds(種子). 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(陰涼的) 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

 

Answer 1

【答案】

1.D

2.B

3.C

【解析】

試題分析：這篇短文主要講述了指物對于我們的重要性以及它們的繁殖方式.

1.根據(jù)第一段Life could not go on if there were no plants.及下文描述，可知沒有植物，人們就會死亡。故選D。

2.短文最后一段主要介紹了不開花植物通過孢子繁殖，故接下來可能要講述的是，孢子如何長成新的植物。故選B。

3.這篇短文主要介紹了指物的兩種繁殖方式,故有可能出自一本科學雜志,選C,一本科學雜志.

考點：科普類說明文閱讀

點評：本文淺顯易懂，層次分明，學生很容易把握文章中心內容。答題中注意帶著問題閱讀短文，一般就能順利找出答題依據(jù)。對于不能直接找到根據(jù)的問題注意聯(lián)系上下文，根據(jù)短文中心總結出正確答案。
