精英家教網 > 初中英語 > 題目詳情

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.
【小題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.
【小題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
【小題3】This passage is most likely to be taken from ________.
A.a story bookB.a novel
C.a science magazineD.a laboratory report


【小題1】D
【小題2】B
【小題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.
【小題1】根據第一段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。
【小題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。
【小題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。對于不能直接找到根據的問題注意聯系上下文,根據短文中心總結出正確答案。

根據短文內容及首字母提示,填寫所缺單詞。
How to be a Green One
What does it mean to be green? “Green is more than just a c 76  .It also means taking special steps to protect the e77  --the water, the land , and the air we breathe. Why is green? Plants are green, and w78  them the earth wouldn’t be such a lovely home for human beings(人類). Here’s a four-step guide to be green:
R79  It!
When you use less of something, you do a good thing for the earth. For example, a shorter shower means you use less water and less fuel(燃料) because your house uses fuel to run the water heater(加熱器)that warms up the water.
Reuse It !
Sometimes we’re a little too willing to throw away the w80 and buy new things. Many times, you no l 81  need something, someone else just might need it. For example, if your baby brother grows out of toys, why not give them to a82  family who has a little kid?
Recycle(回收) It!
Recycling has n83 been easier. Many people will pick it up right in front of your house and they will need it. Tell your mum or dad become “Head of Recycling” for your house.
Enjoy It!
It’s true that p84  is a problem, but the earth is still a large and beautiful place for you to go and study. You can start by v85  the beautiful places in you home town. Go for a hike, visit local nature centres and gardens, climb up mountains and so on.
