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 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.
1.The main idea of the first paragraph is that ______.
A．plants are important for life B．plants cannot grow without air
C．there are many plants in the world D．we can not live without water
2.Plants can make food from______.
A．flower, water and air B．water, sunlight and air
C．air, water and soil D．air, sun and light
3.What can we infer(推断) from the passage ?
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
4.This passage may be taken from______.
A．a medicine book B．a novel
C．a science magazine D．an experiment report
5.The underlined word “protected” in the third paragraph can be replaced by ______.
A．damaged B．polluted C．prevented D．guarded

All plant cells are capable of taking up water. Even dead ones do to a certain degree. Absorption（吸收）of water by dead cell walls makes wood become larger. In common land plants, the living cells of roots take up most of the water. Land plants without roots do exist, however. Those greenish-yellow lichens（苔藓）you see on rocks in the high mountains have no roots. Half a billion years ago, when water plants started to enter the land, the first land plants did not have roots.
Even among the flowering plants, one finds rootless forms. These flowering plants are “the higher plants” because they evolved（进化）recently and are thus considered higher on the evolutionary scale（进化度）. In the Peruvian desert, there grows one of these rootless higher plants, a bromeliad. It is a relative of the pineapple. Even if this plant had roots, they would be of no use, because where the plant grows, it never rains. The plant gets its water only from the dew（露水）it collects at night, when its leaves cool off. Such rootless plants, of course, can be moved with ease, but they will only grow when they are placed out in the open. If they are placed too near a house, the radiation from the heat of the house prevents the leaves from cooling and so prevents dew from forming, and the plant dies. In the southern United States and in Puerto Rico, one sees bromeliads growing high above the streets on the insulation（绝缘物）of electric wires. These plants get their water from rain, and the only soil they ever come in contact with is the dust that may blow on their leaves.
64．From the passage we know that the evolutionary scale is graded according to _______ .
A. evolutionary
cycles B. heights and depths
C. time D. kinds
65．The “bromeliad” is a plant that _______ .
A．has useless roots B. is a pineapple
C．can grow anywhere D. takes up water through its leaves
66．The most suitable title for this passage is “_______ ”.
A. Absorption of water by plants B. Rootless plants
C. Plants in the desert D. Higher plants

If you want your land to keep fertile, you must try to stop soil from being carried away by water or wind. When soil is taken away by flowing water or blowing winds we call it soil erosion. Ways have been found to stop soil erosion, and this is known as soil conservation. One way of stopping soil erosion is to grow small plants such as grass. These plants are referred to a cover crops, whose roots hold the soil tightly together. The rain water can not wash away the soil. When trees and tall bushes are planted at the edges of an open field, soil erosion by strong winds can not take place. The trees and b
ushes, which act as a
very big and firm wall, protect the open land from the winds. The way to stoop soil erosion on slopes is to build terraces on the slope of hillside and mountainside. When the slope of a hillside is cut into “step”, water carrying soil can not run straight down the terraces, which are used to slow down the speed of the flowing water containing much soil in it. In this way most of the soil in the water is left behind on the terraces, much soil in it.
【小题1】What takes place in soil erosion?
| A．Flood happens to the fertile land |
| B．A large quantity of the soil loses away gradually. |
| C．Terraces are built on the slope of hillside or mountainside. |
| D．Plants are grown to protect the open land |
| A．build terraces | B．build walls | C．plant trees | D．plant tall bushes |
| A．because their roots hold soil tightly |
| B．to stop soil from being blown away by winds. |
| C．Because soil erosion causes terrible damages to crops |
| D．To keep the balance of nature |
tle of the passage?| A．What Causes Soil Erosion |
| B．The Importance of Erosion |
| C．Rain Erosion and Wind Erosion |
| D．Erosion and the Way of Tight against Erosion |

Bamboo is one of the nature’s most surprising plants. Many people call this plant a tree, but it is a kind of grass.
Like other kinds of grass, a bamboo plant may be cut very low to the ground, but it will grow back very quickly. A Japanese scientist recorded one bamboo plant that grew almost 1.5 meters in 24 hours! Bamboo grows almost everywhere in the world except Europe. There are more than 1,000 kinds of bamboo that grow around the world on both mountains and plains(平原).
Not all bamboo looks the same. Some bamboo plants are very thin. They may only grow to be a few centimeters wide while others may grow to more than 30 centimeters across. This plant also comes in different colors, from yellow to black to green.
Many Asian countries have been using bamboo for hundreds of years. They often use bamboo for building new buildings. As a matter of fact, the cables (绳索) that hold up the hanging bridge across the Min River in Sichuan are made of bamboo. The bridge has been in use for more than 1,000 years, and is still holding strong.
In Africa, engineers are teaching poor farmers how to find water using bamboo. These African countries need cheap ways to find water because they have no money, and their fields often die from no rain and no water. It seems that bamboo is one of the best things they can use. Bamboo pipes and drills (钻) can help to make the poor thirsty fields to be watered.
41.How is bamboo like grass?
A. It is thin and easy to cut. B. It grows everywhere.
C. It grows quickly after its cut short. D. It is short and green.
42.The sentence “while others may grow to more than 30 centimeters across.” means “Some other bamboo plants may grow to be very _______.”
A. short B. strong C. thick D. tall
43.From the text we know ______.
A. most people call bamboo plant trees
B. a bamboo plant may grow 4.5 meters in three days
C. the bamboo plant changes its colors when it grows
D. a bridge held by bamboo cable was built thousands of years ago
44.Why did the engineers teach the poor farmers in Africa to make use of bamboo?
A. Because it is cheap. B. Because it is colorful.
C. Because it drills fast. D. Because it is used by Asians.
45.Which of the following is NOT true?
A. There are many different kinds of bamboo with different colors.
B. Cables made of bamboo can last for over a thousand years.
C. Bamboo can be used for buildings, bridges and watering projects(工程).
D. Bamboo plants are able to grow well in any part of the world.
