根据短文内容,判断下列句子是否正确,对的涂(A),错的涂(B)。

Plants are very important living things. Life could not go if there were no plants. This is because plants can produce food from the air, water and sunlight. Animals and man cannot produce food from the air, water and sunlight as plants do. Animals get their food by eating plants or other animals which eat plants. So animals and man need plants in order to live.

If you look carefully at the plants around you, you will find that there are two kinds of plants: flowering plants and non-flowering ones.

Flowering plants can make seeds. The seeds are protected by the fruits. Some fruits have one seed. Some have two, three or four. Some have many. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana.

Most non-flowering plants don’t 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 the seeds. When these spores fall on wet and shady places, they usually grow into new plants.  

1.Plants are very important to life.

2.Both animals and plants can produce food from the air, water and sunlight.

3.Banana is a fruit that does not have seeds.

4.All the flowering plants have many seeds.

5.Spores can grow into new plants wherever they fall.

You can’t see any object unless light from that object gets into your eyes.Some of the things you see give off light of their own。The sun,the stars,a lighted lamp are the examples that can be seen by their own light.But most of the things you see are not giving off light of their own.They are just reflecting(反射)light that falls on them from the sun or some other luminous bodies.The moon,for example,doesn’t give off any light of its own.It is not 1uminous.You see it because sunlight falls on it and some of the sunlight reflects on the earth.So moonlight is only second—hand sunlight.
When you look at a book,it sends some of the light which fails on it to your eyes,and you see the book.If light could be kept out from where you’re so that there would be no light from the book to reflect.Then you couldn’t see the book even with your eyes wide open.Light travels so fast that the time in which it travels from the book you’re reading to your eyes is as short as if there were no time at time.Light reaches us from the moon,which is about 380,000 kilometres away,in only a little more than a second.

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

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